feat: 完成 M2 mosh（LAN + tsnet 端到端验证）
- mosh(blinksh/ios C++)+protobuf-lite 交叉编译为 MoshCore.xcframework （CommonCrypto 后端、含 arm64 模拟器 slice；绕 autotools 用 CMake 直编 + 手写 config.h） - tsnet 桥新增 UDP relay（StartMoshRelay：loopback↔tsnet.Dial 逐包搬运） - MoshSession（pipe↔FILE*/pthread/SIGWINCH）+ MoshConnectScanner（TXCore，+4 单测=39） - SSHTerminalModel 编排：SSH 引导 mosh-server→解析 MOSH CONNECT→relay→mosh 接管 - LAN 直连 + mosh-over-tsnet 均端到端验证通过，R1(tsnet UDP 数据报语义) 证伪 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

|

## 仓库结构
|
||||
- `packages/TXCore` — 零依赖纯逻辑：tmux 解析器/layout/`SessionMachine`(会话状态机+退避重连)/`TmuxControlSequence`(DCS 检测)。
|
||||
- `packages/TXTransport` — `SSHSession`(libssh2, 支持外部 fd)/`Transport` 协议；`CSSH`(C shim: 头+modulemap)/`CSSHCore`(binaryTarget)。
|
||||
- `apps/TerminalX/iOS` — `SSHTerminalModel`(连接编排+tsnet+tmux 路由)/`ContentView`/`TmuxController`(tmux 网关)/`TsnetProbe`(M1 自检)。
|
||||
- `vendor/` — 所有非 Swift 依赖本地化：`libghostty-spm`(GhosttyKit)/`MSDisplayLink`/`libssh2`/`mbedtls`/`tsnet-bridge`(Go)。
|
||||
- `artifacts/` — 预编译 xcframework（gitignore）：`CSSHCore`/`TsnetBridge`。
|
||||
- `packages/TXTransport` — `SSHSession`(libssh2, 支持外部 fd)/`MoshSession`(mosh_main 桥)/`Transport` 协议；C shim: `CSSH`+`CSSHCore`(libssh2)、`CMosh`+`MoshCore`(mosh)。
|
||||
- `apps/TerminalX/iOS` — `SSHTerminalModel`(连接编排+tsnet+tmux 路由+mosh 编排)/`ContentView`/`TmuxController`(tmux 网关)/`TsnetProbe`(M1 自检)。
|
||||
- `vendor/` — 所有非 Swift 依赖本地化：`libghostty-spm`(GhosttyKit)/`MSDisplayLink`/`libssh2`/`mbedtls`/`tsnet-bridge`(Go)/`mosh`(blinksh/ios 分支)/`protobuf`(3.21.12)；`build/mosh/`(手写 config.h+CMakeLists)。
|
||||
- `artifacts/` — 预编译 xcframework（**有意提交**，非 gitignore）：`CSSHCore`/`TsnetBridge`/`MoshCore`。
|
||||
|
||||
## 约定 & 坑
|
||||
- **CSSHCore 必须 library-only**（无 Headers/modulemap）；libssh2 的 Swift module 由包内 `CSSH` C target 提供。否则与 GhosttyKit 撞 `include/module.modulemap`。
|
||||
- **CSSHCore/MoshCore 必须 library-only**（无 Headers/modulemap）；Swift module 由包内 `CSSH`/`CMosh` C target 提供。否则与 GhosttyKit 撞 `include/module.modulemap`。
|
||||
- **mosh 构建**：绕过 autotools 用 CMake 直编 `src/*.cc`（手写 `build/mosh/config.h`）；crypto 用 CommonCrypto(`USE_APPLE_COMMON_CRYPTO_AES=1`)；用 `terminaldisplayinit_ios.cc`(无 terminfo)；已 patch 3 处 vendored 源(`::bind` 消歧义 / curses include 包 `#if !IOS_CONTROLLER` / 去 iOS 禁用 `system()`)；protobuf 只需 lite runtime，`.pb.cc` 已 checkin。
|
||||
- **protoc 装不了不是问题**：用源码 CMake 编一个 host protoc 生成 `.pb.cc` 即可（一次性，产物 checkin）。
|
||||
- **一进程一个 Go runtime、只一次 gomobile bind**（全在 `tsnetbridge` 包）。
|
||||
- **Swift `\r\n` 是单个 Character（扩展字形簇）**：判行尾用 `Character.isNewline`，不能 `c != "\r"`（`MoshConnectScanner` 曾踩）。
|
||||
- **Swift6 `SendNonSendable` pass 可能崩溃**（`pthread_create`+`Unmanaged` 上下文+C 入口的组合）：改用 `Foundation.Thread`+线程内 `pthread_self()` 规避（见 `MoshSession`）。
|
||||
- GhosttyKit 的 `InMemoryTerminalSession.receive` 在 surface 未 attach 时**丢弃**写入 → 用 `OutputGate` 缓冲到 `surfaceSize != nil` 再 flush。
|
||||
- tmux `-CC attach` **不推 %window-add** → 必须主动 `list-windows` 枚举。
|
||||
- SourceKit "No such module" 是索引噪声，**以 `swift build`/`xcodebuild` 为准**。

## 7. 下一步建议（按价值）
|
||||
1. **M2 mosh over tsnet**：接 `blinksh/mosh`(libmoshios C++,依赖 protobuf) 交叉编译成 xcframework(参考 `build-cssh.sh` 模式) → 本地 UDP relay(mosh 连 127.0.0.1:N，Go 侧 `tsnet` UDP `ListenPacket`/`Dial` 转发；bridge 加 UDP relay 方法，类比 `DialTCPFD`)。SSH 先起 `mosh-server` 拿 key+port。**需用户提供装了 mosh-server 的 tailnet 主机**做端到端。
|
||||
2. **tmux 多 pane 分屏**：`TmuxLayout` 已能解析布局树 → 把 window 内多 pane 渲染成 SwiftUI 分屏（每 pane 一 surface）。
|
||||
3. **M4 安全**：known_hosts 固定 + SE 密钥。
|
||||
4. **产品化**：主机列表持久化(Keychain)、多标签(非 tmux)、软键盘运维工具栏(GhosttyKit 内建，接线即可)。
|
||||
1. **M2 mosh 打磨**（功能已通，打磨项）：`activateMosh` 写死 80x24 初值（靠首次 resize 纠正）；SSH 会话在 mosh 接管后保持 idle 未关（占一条连接）；`MoshSession.close()` 后 mosh 线程可能滞留（阻塞主循环，见 TODO）；moshiosbridge.cc 顶部 `fwrite("Hello from the Bridge!")` 调试行可清理；`SSHTerminalModel` 里 `NSLog("MOSHDBG …")` 诊断日志可按需保留/删除；mosh-server 引导后远端会累积 detached 会话（`mosh-server new` 每次新建），可考虑复用或清理。**挂起→恢复<3s 门（M3）待专门测**。
|
||||
3. **tmux 多 pane 分屏**：`TmuxLayout` 已能解析布局树 → 把 window 内多 pane 渲染成 SwiftUI 分屏（每 pane 一 surface）。
|
||||
4. **M4 安全**：known_hosts 固定 + SE 密钥。
|
||||
5. **产品化**：主机列表持久化(Keychain)、多标签(非 tmux)、软键盘运维工具栏(GhosttyKit 内建，接线即可)。
|
||||
|
||||
## 8. 测试资源（用户提供，**凭据勿写入仓库/勿硬编码**，每次向用户索取）
|
||||
- 一台局域网 macOS(有 tmux)、一台 tailnet 内 online 的 Ubuntu VM(vohive-vm)、一个 tailnet auth key（ephemeral，可能过期，用户会给新的）。用于直连 SSH / SSH-over-tsnet / tmux / M2 mosh 端到端验证。
|
||||
- 一台局域网 macOS(有 tmux + **mosh-server**，如 MacBook-Air-M1；fish 为默认 shell，`mosh-server` 在 `/opt/homebrew/bin` 且交互 shell PATH 可见)、一台 tailnet 内 online 的 Ubuntu VM(vohive-vm)、一个 tailnet auth key（ephemeral，可能过期，用户会给新的）。用于直连 SSH / SSH-over-tsnet / tmux / M2 mosh 端到端验证。凭据每次向用户即时索取。
|
||||
- tailnet 是 `tail3b5057.ts.net`，已见节点：vohive-vm(linux)、iphone-air、ipad-pro、macbook-air-m1、macbook-air。

GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too, receive
|
||||
or can get the source code. And you must show them these terms so they
|
||||
know their rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software: you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation, either version 3 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program. If not, see <http://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
<program> Copyright (C) <year> <name of author>
|
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, your program's commands
|
||||
might be different; for a GUI interface, you would use an "about box".
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
||||
For more information on this, and how to apply and follow the GNU GPL, see
|
||||
<http://www.gnu.org/licenses/>.
|
||||
|
||||
The GNU General Public License does not permit incorporating your program
|
||||
into proprietary programs. If your program is a subroutine library, you
|
||||
may consider it more useful to permit linking proprietary applications with
|
||||
the library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License. But first, please read
|
||||
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

#iOSClient for Mosh
|
||||
These are a set of small changes to make Mosh compile for iOS as
|
||||
a separate library that can be linked into applications. Please do
|
||||
not use to compile mosh-client or mosh-server. You can use a separate
|
||||
script [Build Mosh](https://github.com/blinksh/build-mosh) and it is
|
||||
currently being used in [Blink](https://github.com/blinksh/blink).
|
||||
|
||||
There are four main changes to the original Mosh code, that we hope to
|
||||
integrate at some point with the main branch:
|
||||
- iOSClient as a new main loop for the library.
|
||||
- Multithread code suppport.
|
||||
- Makefiles support for the iOS version.
|
||||
- Bug fixes (sockets, etc...)
|
||||
|
||||
Original Mosh can be found on [Mosh](https://github.com/mobile-shell/mosh)

Description: Mobile shell that supports roaming and intelligent local echo
|
||||
Mosh is a remote terminal application that supports:
|
||||
- intermittent network connectivity,
|
||||
- roaming to different IP address without dropping the connection, and
|
||||
- intelligent local echo and line editing to reduce the effects
|
||||
of "network lag" on high-latency connections.

Mosh is a remote terminal application that supports:
|
||||
- intermittent network connectivity,
|
||||
- roaming to different IP address without dropping the connection, and
|
||||
- intelligent local echo and line editing to reduce the effects
|
||||
of "network lag" on high-latency connections.

# SYNOPSIS

#
|
||||
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's compiler
|
||||
# or gives an error. (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_LIBRARY(VARIABLE-PREFIX, HEADER-FILE, LIBRARY-FILE,
|
||||
# [ACTION-IF-FOUND], [ACTION-IF-NOT_FOUND])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Provides a generic test for a given library, similar in concept to the
|
||||
# PKG_CHECK_MODULES macro used by pkg-config.
|
||||
#
|
||||
# Most simplest libraries can be checked against simply through the
|
||||
# presence of a header file and a library to link to. This macro allows to
|
||||
# wrap around the test so that it doesn't have to be recreated each time.
|
||||
#
|
||||
# Rather than define --with-$LIBRARY arguments, it uses variables in the
|
||||
# same way that PKG_CHECK_MODULES does. It doesn't, though, use the same
|
||||
# names, since you shouldn't provide a value for LIBS or CFLAGS but rather
|
||||
# for LDFLAGS and CPPFLAGS, to tell the linker and compiler where to find
|
||||
# libraries and headers respectively.
|
||||
#
|
||||
# If the library is find, HAVE_PREFIX is defined, and in all cases
|
||||
# PREFIX_LDFLAGS and PREFIX_CPPFLAGS are substituted.
|
||||
#
|
||||
# Example:
|
||||
#
|
||||
# AX_CHECK_LIBRARY([LIBEVENT], [event.h], [event], [],
|
||||
# [AC_MSG_ERROR([Unable to find libevent])])

# SYNOPSIS

#
|
||||
# AX_WITH_CURSES
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro checks whether a SysV or X/Open-compatible Curses library is
|
||||
# present, along with the associated header file. The NcursesW
|
||||
# (wide-character) library is searched for first, followed by Ncurses,
|
||||
# then the system-default plain Curses. The first library found is the
|
||||
# one returned.
|
||||
#
|
||||
# The following options are understood: --with-ncursesw, --with-ncurses,
|
||||
# --without-ncursesw, --without-ncurses. The "--with" options force the
|
||||
# macro to use that particular library, terminating with an error if not
|
||||
# found. The "--without" options simply skip the check for that library.
|
||||
# The effect on the search pattern is:
|
||||
#
|
||||
# (no options) - NcursesW, Ncurses, Curses
|
||||
# --with-ncurses --with-ncursesw - NcursesW only [*]
|
||||
# --without-ncurses --with-ncursesw - NcursesW only [*]
|
||||
# --with-ncursesw - NcursesW only [*]
|
||||
# --with-ncurses --without-ncursesw - Ncurses only [*]
|
||||
# --with-ncurses - NcursesW, Ncurses [**]
|
||||
# --without-ncurses --without-ncursesw - Curses only
|
||||
# --without-ncursesw - Ncurses, Curses
|
||||
# --without-ncurses - NcursesW, Curses
|
||||
#
|
||||
# [*] If the library is not found, abort the configure script.
|
||||
#
|
||||
# [**] If the second library (Ncurses) is not found, abort configure.
|
||||
#
|
||||
# The following preprocessor symbols may be defined by this macro if the
|
||||
# appropriate conditions are met:
|
||||
#
|
||||
# HAVE_CURSES - if any SysV or X/Open Curses library found
|
||||
# HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions
|
||||
# HAVE_CURSES_COLOR - if library supports color (enhanced functions)
|
||||
# HAVE_CURSES_OBSOLETE - if library supports certain obsolete features
|
||||
# HAVE_NCURSESW - if NcursesW (wide char) library is to be used
|
||||
# HAVE_NCURSES - if the Ncurses library is to be used

# The following output variable is defined by this macro; it is precious
|

# and may be overridden on the ./configure command line:
|
||||
#
|
||||
# CURSES_LIB - library to add to xxx_LDADD
|
||||
#
|
||||
# The library listed in CURSES_LIB is NOT added to LIBS by default. You
|
||||
# need to add CURSES_LIB to the appropriate xxx_LDADD line in your
|
||||
# Makefile.am. For example:
|
||||
#
|
||||
# prog_LDADD = @CURSES_LIB@
|
||||
#
|
||||
# If CURSES_LIB is set on the configure command line (such as by running
|
||||
# "./configure CURSES_LIB=-lmycurses"), then the only header searched for
|
||||
# is <curses.h>. The user may use the CPPFLAGS precious variable to
|
||||
# override the standard #include search path. If the user needs to
|
||||
# specify an alternative path for a library (such as for a non-standard
|
||||
# NcurseW), the user should use the LDFLAGS variable.
|
||||
#
|
||||
# The following shell variables may be defined by this macro:
|
||||
#
|
||||
# ax_cv_curses - set to "yes" if any Curses library found
|
||||
# ax_cv_curses_enhanced - set to "yes" if Enhanced functions present
|
||||
# ax_cv_curses_color - set to "yes" if color functions present
|
||||
# ax_cv_curses_obsolete - set to "yes" if obsolete features present
|
||||
#
|
||||
# ax_cv_ncursesw - set to "yes" if NcursesW library found
|
||||
# ax_cv_ncurses - set to "yes" if Ncurses library found
|
||||
# ax_cv_plaincurses - set to "yes" if plain Curses library found
|
||||
# ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no"
|
||||
#
|
||||
# These variables can be used in your configure.ac to determine the level
|
||||
# of support you need from the Curses library. For example, if you must
|
||||
# have either Ncurses or NcursesW, you could include:
|
||||
#
|
||||
# AX_WITH_CURSES
|
||||
# if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
|
||||
# AX_MSG_ERROR([requires either NcursesW or Ncurses library])
|
||||
# fi
|
||||
#
|
||||
# If any Curses library will do (but one must be present and must support
|
||||
# color), you could use:
|
||||
#
|
||||
# AX_WITH_CURSES
|
||||
# if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then

# AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
|
||||
# fi
|
||||
#
|
||||
# Certain preprocessor symbols and shell variables defined by this macro
|
||||
# can be used to determine various features of the Curses library. In
|
||||
# particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
|
||||
# library found conforms to the traditional SysV and/or X/Open Base Curses
|
||||
# definition. Any working Curses library conforms to this level.
|
||||
#
|
||||
# HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
|
||||
# library supports the X/Open Enhanced Curses definition. In particular,
|
||||
# the wide-character types attr_t, cchar_t and wint_t, the functions
|
||||
# wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
|
||||
# are checked. The Ncurses library does NOT conform to this definition,
|
||||
# although NcursesW does.
|
||||
#
|
||||
# HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
|
||||
# supports color functions and macros such as COLOR_PAIR, A_COLOR,
|
||||
# COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the
|
||||
# X/Open Base Curses definition, but are part of the Enhanced set of
|
||||
# functions. The Ncurses library DOES support these functions, as does
|
||||
# NcursesW.
|
||||
#
|
||||
# HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
|
||||
# library supports certain features present in SysV and BSD Curses but not
|
||||
# defined in the X/Open definition. In particular, the functions
|
||||
# getattrs(), getcurx() and getmaxx() are checked.
|
||||
#
|
||||
# To use the HAVE_xxx_H preprocessor symbols, insert the following into
|
||||
# your system.h (or equivalent) header file:
|
||||
#
|
||||
# #if defined HAVE_NCURSESW_CURSES_H
|
||||
# # include <ncursesw/curses.h>
|
||||
# #elif defined HAVE_NCURSESW_H
|
||||
# # include <ncursesw.h>
|
||||
# #elif defined HAVE_NCURSES_CURSES_H
|
||||
# # include <ncurses/curses.h>
|
||||
# #elif defined HAVE_NCURSES_H
|
||||
# # include <ncurses.h>
|
||||
# #elif defined HAVE_CURSES_H
|
||||
# # include <curses.h>
|
||||
# #else
|
||||
# # error "SysV or X/Open-compatible Curses header file required"
|
||||
# #endif
|
||||
#
|
||||
# For previous users of this macro: you should not need to change anything
|
||||
# in your configure.ac or Makefile.am, as the previous (serial 10)
|
||||
# semantics are still valid. However, you should update your system.h (or
|
||||
# equivalent) header file to the fragment shown above. You are encouraged
|
||||
# also to make use of the extended functionality provided by this version
|
||||
# of AX_WITH_CURSES, as well as in the additional macros
|
||||
# AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.

\f0\fs26 \cf0 GNU GENERAL PUBLIC LICENSE\
|
||||
Version 3, 29 June 2007\
|
||||
\
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>\
|
||||
Everyone is permitted to copy and distribute verbatim copies\
|
||||
of this license document, but changing it is not allowed.\
|
||||
\
|
||||
Preamble\
|
||||
\
|
||||
The GNU General Public License is a free, copyleft license for software and other kinds of works.\
|
||||
\
|
||||
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.\
|
||||
\
|
||||
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.\
|
||||
\
|
||||
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.\
|
||||
\
|
||||
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.\
|
||||
\
|
||||
Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.\
|
||||
\
|
||||
For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.\
|
||||
\
|
||||
Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.\
|
||||
\
|
||||
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.\
|
||||
\
|
||||
The precise terms and conditions for copying, distribution and modification follow.\
|
||||
\
|
||||
TERMS AND CONDITIONS\
|
||||
\
|
||||
0. Definitions.\
|
||||
\
|
||||
"This License" refers to version 3 of the GNU General Public License.\
|
||||
\
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.\
|
||||
\
|
||||
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.\
|
||||
\
|
||||
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.\
|
||||
\
|
||||
A "covered work" means either the unmodified Program or a work based on the Program.\
|
||||
\
|
||||
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.\
|
||||
\
|
||||
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.\
|
||||
\
|
||||
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.\
|
||||
\
|
||||
1. Source Code.\
|
||||
\
|
||||
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.\
|
||||
\
|
||||
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.\
|
||||
\
|
||||
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.\
|
||||
\
|
||||
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.\
|
||||
\
|
||||
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.\
|
||||
\
|
||||
The Corresponding Source for a work in source code form is that same work.\
|
||||
\
|
||||
2. Basic Permissions.\
|
||||
\
|
||||
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.\
|
||||
\
|
||||
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.\
|
||||
\
|
||||
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.\
|
||||
\
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.\
|
||||
\
|
||||
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.\
|
||||
\
|
||||
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.\
|
||||
\
|
||||
4. Conveying Verbatim Copies.\
|
||||
\
|
||||
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.\
|
||||
\
|
||||
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.\
|
||||
\
|
||||
5. Conveying Modified Source Versions.\
|
||||
\
|
||||
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:\
|
||||
\
|
||||
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.\
|
||||
\
|
||||
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".\
|
||||
\
|
||||
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.\
|
||||
\
|
||||
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.\
|
||||
\
|
||||
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.\
|
||||
\
|
||||
6. Conveying Non-Source Forms.\
|
||||
\
|
||||
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:\
|
||||
\
|
||||
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.\
|
||||
\
|
||||
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.\
|
||||
\
|
||||
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.\
|
||||
\
|
||||
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.\
|
||||
\
|
||||
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.\
|
||||
\
|
||||
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.\
|
||||
\
|
||||
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.\
|
||||
\
|
||||
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.\
|
||||
\
|
||||
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).\
|
||||
\
|
||||
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.\
|
||||
\
|
||||
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.\
|
||||
\
|
||||
7. Additional Terms.\
|
||||
\
|
||||
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.\
|
||||
\
|
||||
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.\
|
||||
\
|
||||
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:\
|
||||
\
|
||||
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or\
|
||||
\
|
||||
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or\
|
||||
\
|
||||
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or\
|
||||
\
|
||||
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or\
|
||||
\
|
||||
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or\
|
||||
\
|
||||
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.\
|
||||
\
|
||||
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.\
|
||||
\
|
||||
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.\
|
||||
\
|
||||
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.\
|
||||
\
|
||||
8. Termination.\
|
||||
\
|
||||
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).\
|
||||
\
|
||||
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.\
|
||||
\
|
||||
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.\
|
||||
\
|
||||
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.\
|
||||
\
|
||||
9. Acceptance Not Required for Having Copies.\
|
||||
\
|
||||
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.\
|
||||
\
|
||||
10. Automatic Licensing of Downstream Recipients.\
|
||||
\
|
||||
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.\
|
||||
\
|
||||
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.\
|
||||
\
|
||||
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.\
|
||||
\
|
||||
11. Patents.\
|
||||
\
|
||||
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".\
|
||||
\
|
||||
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.\
|
||||
\
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.\
|
||||
\
|
||||
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.\
|
||||
\
|
||||
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.\
|
||||
\
|
||||
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.\
|
||||
\
|
||||
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.\
|
||||
\
|
||||
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.\
|
||||
\
|
||||
12. No Surrender of Others' Freedom.\
|
||||
\
|
||||
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.\
|
||||
\
|
||||
13. Use with the GNU Affero General Public License.\
|
||||
\
|
||||
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.\
|
||||
\
|
||||
14. Revised Versions of this License.\
|
||||
\
|
||||
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.\
|
||||
\
|
||||
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.\
|
||||
\
|
||||
If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.\
|
||||
\
|
||||
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.\
|
||||
\
|
||||
15. Disclaimer of Warranty.\
|
||||
\
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\
|
||||
\
|
||||
16. Limitation of Liability.\
|
||||
\
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.\
|
||||
\
|
||||
17. Interpretation of Sections 15 and 16.\
|
||||
\
|
||||
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.\

|

END OF TERMS AND CONDITIONS\
|
||||
\
|
||||
How to Apply These Terms to Your New Programs\
|
||||
\
|
||||
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.\
|
||||
\
|
||||
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.\
|
||||
\
|
||||
<one line to give the program's name and a brief idea of what it does.>\
|
||||
Copyright (C) <year> <name of author>\
|
||||
\
|
||||
This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.\
|
||||
\
|
||||
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.\
|
||||
\
|
||||
You should have received a copy of the GNU General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.\
|
||||
\
|
||||
Also add information on how to contact you by electronic and paper mail.\
|
||||
\
|
||||
If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:\
|
||||
\
|
||||
<program> Copyright (C) <year> <name of author> This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.\
|
||||
\
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".\
|
||||
\
|
||||
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see <http://www.gnu.org/licenses/>.\
|
||||
\
|
||||
The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read <http://www.gnu.org/philosophy/why-not-lgpl.html>.}

\f0\b\fs56 \cf0 Mosh: the mobile shell\
|
||||
\pard\pardeftab720\sa300
|
||||
|
||||
\b0\fs28 \cf2 Mosh is a remote terminal application that supports intermittent connectivity, allows roaming, and provides speculative local echo and line editing of user keystrokes.\
|
||||
It aims to support the typical interactive uses of SSH, plus:\
|
||||
\pard\tx220\tx720\pardeftab720\li720\fi-720
|
||||
\ls1\ilvl0\cf2 {\listtext \'95 }Mosh keeps the session alive if the client goes to sleep and wakes up later, or temporarily loses its Internet connection.\
|
||||
{\listtext \'95 }Mosh allows the client and server to "roam" and change IP addresses, while keeping the connection alive. Unlike SSH, Mosh can be used while switching between Wi-Fi networks or from Wi-Fi to cellular data to wired Ethernet.\
|
||||
\pard\tx220\tx720\pardeftab720\li720\fi-720\sa300
|
||||
\ls1\ilvl0\cf2 {\listtext \'95 }The Mosh client runs a predictive model of the server's behavior in the background and tries to guess intelligently how each keystroke will affect the screen state. When it is confident in its predictions, it will show them to the user while waiting for confirmation from the server. Most typing and uses of the left- and right-arrow keys can be echoed immediately.\uc0\u8232 As a result, Mosh is usable on high-latency links, e.g. on a cellular data connection or spotty Wi-Fi. In distinction from previous attempts at local echo modes in other protocols, Mosh works properly with full-screen applications such as emacs, vi, alpine, and irssi, and automatically recovers from occasional prediction errors within an RTT. On high-latency links, Mosh underlines its predictions while they are outstanding and removes the underline when they are confirmed by the server.\
|
||||
\pard\pardeftab720\sa300
|
||||
\cf2 Mosh does not support X forwarding or the non-interactive uses of SSH, including port forwarding.\
|
||||
\pard\pardeftab720\sa200
|
||||
|
||||
\b\fs48 \cf0 Other features\
|
||||
\pard\tx220\tx720\pardeftab720\li720\fi-720
|
||||
\ls2\ilvl0
|
||||
\b0\fs28 \cf2 {\listtext \'95 }Mosh adjusts its frame rate so as not to fill up network queues on slow links, so "Control-C" always works within an RTT to halt a runaway process.\
|
||||
{\listtext \'95 }Mosh warns the user when it has not heard from the server in a while.\
|
||||
{\listtext \'95 }Mosh supports lossy links that lose a significant fraction of their packets.\
|
||||
{\listtext \'95 }Mosh handles some Unicode edge cases better than SSH and existing terminal emulators by themselves, but requires a UTF-8 environment to run.\
|
||||
{\listtext \'95 }Mosh leverages SSH to set up the connection and authenticate users. Mosh does not contain any privileged (root) code.\
|
||||
\
|
||||
\pard\pardeftab720\sa200
|
||||
|
||||
\b\fs48 \cf0 Usage\
|
||||
\pard\pardeftab720\sa300
|
||||
|
||||
\b0\fs28 \cf2 The
|
||||
\f1\fs24 \cb3 mosh-client
|
||||
\f0\fs28 \cb1 binary must be installed on the user's machine, and the
|
||||
\f1\fs24 \cb3 mosh-server
|
||||
\f0\fs28 \cb1 binary on the remote host.\
|
||||
The user runs:\
|
||||
\pard\pardeftab720
|
||||
|
||||
\f1\fs24 \cf2 \cb3 $ mosh [user@]host\
|
||||
\pard\pardeftab720\sa300
|
||||
|
||||
\f0\fs28 \cf2 \cb1 A command may also be specified, for example:\
|
||||
\pard\pardeftab720
|
||||
|
||||
\f1\fs24 \cf2 \cb3 $ mosh host -- screen -r\
|
||||
\pard\pardeftab720\sa300
|
||||
|
||||
\f0\fs28 \cf2 \cb1 If the
|
||||
\f1\fs24 \cb3 mosh-client
|
||||
\f0\fs28 \cb1 or
|
||||
\f1\fs24 \cb3 mosh-server
|
||||
\f0\fs28 \cb1 binaries are installed outside the user's PATH,
|
||||
\f1\fs24 \cb3 mosh
|
||||
\f0\fs28 \cb1 accepts the arguments
|
||||
\f1\fs24 \cb3 --client=PATH
|
||||
\f0\fs28 \cb1 and
|
||||
\f1\fs24 \cb3 --server=PATH
|
||||
\f0\fs28 \cb1 to select alternate locations. More options are documented in the mosh(1) manual page.\
|
||||
Mosh supports 256-color mode as long as the user's own terminal does. Generally this means the
|
||||
\f1\fs24 \cb3 TERM
|
||||
\f0\fs28 \cb1 environment variable must be set to
|
||||
\f1\fs24 \cb3 xterm-256color
|
||||
\f0\fs28 \cb1 or
|
||||
\f1\fs24 \cb3 screen-256color-bce
|
||||
\f0\fs28 \cb1 before running
|
||||
\f1\fs24 \cb3 mosh
|
||||
\f0\fs28 \cb1 .\
|
||||
\pard\pardeftab720\sa200
|
||||
|
||||
\b\fs48 \cf0 How it works\
|
||||
\pard\pardeftab720\sa300
|
||||
|
||||
\b0\fs28 \cf2 The
|
||||
\f1\fs24 \cb3 mosh
|
||||
\f0\fs28 \cb1 program will SSH to
|
||||
\f1\fs24 \cb3 user@host
|
||||
\f0\fs28 \cb1 to establish the connection. SSH may prompt the user for a password or use public-key authentication to log in.\
|
||||
From this point,
|
||||
\f1\fs24 \cb3 mosh
|
||||
\f0\fs28 \cb1 runs the
|
||||
\f1\fs24 \cb3 mosh-server
|
||||
\f0\fs28 \cb1 process (as the user) on the server machine. The server process listens on a high UDP port and sends its port number and an AES-128 secret key back to the client over SSH. The SSH connection is then shut down and the terminal session begins over UDP.\
|
||||
If the client changes IP addresses, the server will begin sending to the client on the new IP address within a few seconds.\
|
||||
To function, Mosh requires UDP datagrams to be passed between client and server. By default,
|
||||
\f1\fs24 \cb3 mosh
|
||||
\f0\fs28 \cb1 uses a port number between 60000 and 61000, but the user can select a particular port with the -p option.\

.SH DESCRIPTION
|
||||
\fBmosh-client\fP is a helper program for the
|
||||
.BR mosh (1)
|
||||
remote terminal application.
|
||||
|
||||
\fBmosh\fP itself is a setup script that establishes an SSH
|
||||
connection, runs the server-side helper \fBmosh-server\fP,
|
||||
and collects the server's port number and session key.
|
||||
|
||||
\fBmosh\fP then executes \fBmosh-client\fP with the server's IP
|
||||
address, port, and session key. \fBmosh-client\fP runs for
|
||||
the lifetime of the connection.
|
||||
|
||||
The 22-byte base64 session key given by \fBmosh-server\fP is supplied
|
||||
in the MOSH_KEY environment variable. This represents a 128-bit AES
|
||||
key that protects the integrity and confidentiality of the session.
|
||||
|
||||
For constructing new setup wrappers for remote execution facilities
|
||||
other than SSH, it may be necessary to invoke \fBmosh-client\fP
|
||||
directly.
|
||||
|
||||
With the \-c option, \fBmosh-client\fP instead prints the number of colors
|
||||
of the terminal given by the TERM environment variable.

.SH DESCRIPTION
|
||||
\fBmosh-server\fP is a helper program for the
|
||||
.BR mosh(1)
|
||||
remote terminal application.
|
||||
|
||||
\fBmosh-server\fP binds to a high UDP port and chooses an encryption
|
||||
key to protect the session. It prints both on standard output,
|
||||
detaches from the terminal, and waits for the \fBmosh-client\fP to
|
||||
establish a connection. It will exit if no client has contacted
|
||||
it within 60 seconds.
|
||||
|
||||
By default, \fBmosh-server\fP binds to a port between 60000 and
|
||||
61000 and executes the user's login shell.
|
||||
|
||||
On platforms with \fButempter\fP, \fBmosh-server\fP maintains an entry
|
||||
in the
|
||||
.BR utmp(5)
|
||||
file to indicate its process ID, whether the session is connected,
|
||||
and the client's current IP address.
|
||||
|
||||
\fBmosh-server\fP exits when the client terminates the connection.
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||

|
||||
command-line options.

|
||||
UDP port number or port-range to bind
|
||||
|
||||
.TP
|
||||
.B \-c \fICOLORS\fP
|
||||
Number of colors to advertise to applications through TERM (e.g. 8, 256)
|
||||
|
||||
.TP
|
||||
.B \-l \fINAME=VALUE\fP
|
||||
Locale-related environment variable to try as part of a fallback
|
||||
environment, if the startup environment does not specify a character
|
||||
set of UTF-8.
|
||||
|
||||
.SH ENVIRONMENT VARIABLES
|
||||
These variables allow server-side configuration of Mosh's behavior.
|
||||
They may be set by administrators in system login/rc files,
|
||||
/etc/login.conf, or similar mechanisms, or users in their shell's
|
||||
login/rc files. \fBmosh-server\fP passes these variables to the login
|
||||
session and shell that it starts, but changing them there will have no
|
||||
effect.
|
||||
|
||||
.TP
|
||||
.B MOSH_SERVER_NETWORK_TMOUT
|
||||
If this variable is set to a positive integer number, it specifies how
|
||||
long (in seconds) \fBmosh-server\fP will wait to receive an update from the
|
||||
client before exiting. Since \fPmosh\fP is very useful for mobile
|
||||
clients with intermittent operation and connectivity, we suggest
|
||||
setting this variable to a high value, such as 604800 (one week) or
|
||||
2592000 (30 days). Otherwise, \fBmosh-server\fP will wait
|
||||
indefinitely for a client to reappear. This variable is somewhat
|
||||
similar to the \fBTMOUT\fP variable found in many Bourne shells.
|
||||
However, it is not a login-session inactivity timeout; it only applies
|
||||
to network connectivity.
|
||||
|
||||
.TP
|
||||
.B MOSH_SERVER_SIGNAL_TMOUT
|
||||
If this variable is set to a positive integer number, it specifies how
|
||||
long (in seconds) \fBmosh-server\fP will ignore SIGUSR1 while waiting
|
||||
to receive an update from the client. Otherwise, \fBSIGUSR1\fP will
|
||||
always terminate \fBmosh-server\fP. Users and administrators may
|
||||
implement scripts to clean up disconnected Mosh sessions. With this
|
||||
variable set, a user or administrator can issue
|
||||
|
||||
.nf
|
||||
$ pkill -SIGUSR1 mosh-server
|
||||
.fi
|
||||
|
||||
to kill disconnected sessions without killing connected login
|
||||
sessions.

.SH DESCRIPTION
|
||||
\fBmosh\fP (mobile shell) is a remote terminal application that
|
||||
supports intermittent connectivity, allows roaming, and provides
|
||||
speculative local echo and line editing of user keystrokes.
|
||||
|
||||
Compared with \fBssh\fP, \fBmosh\fP is more robust \(em its
|
||||
connections stay up across sleeps and changes in the client's IP
|
||||
address \(em and more responsive, because the protocol is tolerant of
|
||||
packet loss and the client can echo most keystrokes immediately,
|
||||
without waiting for a network round-trip.
|
||||
|
||||
\fBmosh\fP uses \fBssh\fP to establish a connection to the remote host
|
||||
and authenticate with existing means (e.g., public-key authentication
|
||||
or a password). \fBmosh\fP executes the unprivileged \fBmosh-server\fP
|
||||
helper program on the server, then closes the SSH connection and
|
||||
starts the \fBmosh-client\fP, which establishes a long-lived datagram
|
||||
connection over UDP.
|
||||
|
||||
To improve responsiveness, \fBmosh\fP runs a predictive model of the
|
||||
server's behavior in the background, trying to guess the effect of
|
||||
each keystroke on the screen. It makes predictions for normal typing,
|
||||
backspace, and the left- and right-arrow keys. When it is confident,
|
||||
\fBmosh\fP displays the predictions without waiting for the
|
||||
server. The predictive model must prove itself anew on each row of the
|
||||
terminal and after each control character, so \fBmosh\fP avoids
|
||||
echoing passwords or non-echoing editor commands.
|
||||
|
||||
By default, \fBmosh\fP shows its predictions only on high-latency
|
||||
connections and to smooth out network glitches. (On longer-latency
|
||||
links, the predicted cells are underlined until confirmed by the
|
||||
server.) Occasional echo mistakes are corrected within a network
|
||||
round-trip and do not cause lasting effect.
|
||||
|
||||
\fBmosh\fP does not support X forwarding or the non-interactive uses
|
||||
of SSH, including port forwarding or sshfs. \fBmosh\fP works through
|
||||
typical client-side network address translators but requires UDP to
|
||||
pass between client and server. By default, \fBmosh\fP uses the ports
|
||||
between 60000 and 61000, but allows the user to request a particular
|
||||
UDP port instead.
|
||||
|
||||
\fBmosh\fP will do its best to arrange a UTF-8 character set locale on
|
||||
the client and server. The client must have locale-related environment
|
||||
variables that specify UTF-8. \fBmosh\fP will pass these client
|
||||
variables to the \fBmosh-server\fP on its command line, but in most
|
||||
cases they will not need to be used. \fBmosh-server\fP first attempts
|
||||
to use its own locale-related environment variables, which come from
|
||||
the system default configuration (sometimes /etc/default/locale) or
|
||||
from having been passed over the SSH connection. But if these
|
||||
variables don't call for the use of UTF-8, \fBmosh-server\fP will
|
||||
apply the locale-related environment variables from the client and try
|
||||
again.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \fIcommand\fP
|
||||
Command to run on remote host. By default, \fBmosh\fP executes a login shell.
|
||||
|
||||
.TP
|
||||
.B \-\-client=\fIPATH\fP
|
||||
path to client helper on local machine (default: "mosh-client")
|
||||
|
||||
.TP
|
||||
.B \-\-server=\fICOMMAND\fP
|
||||
command to run server helper on remote machine (default: "mosh-server")
|
||||
|
||||
The server helper is unprivileged and can be installed in the user's
|
||||
home directory.
|
||||
|
||||
This option can be used to set environment variables for the server by
|
||||
using the
|
||||
.BR env (1)
|
||||
command to wrap the actual server command. See
|
||||
.BR mosh-server (1)
|
||||
for available environment variables.
|
||||
|
||||
.TP
|
||||
.B \-\-ssh=\fICOMMAND\fP
|
||||
OpenSSH command to remotely execute mosh-server on remote machine (default: "ssh")
|
||||
|
||||
An alternate ssh port can be specified with, \fIe.g.\fP, \-\-ssh="ssh \-p 2222".
|
||||
|
||||
.TP
|
||||
.B \-\-predict=\fIWHEN\fP
|
||||
Controls use of speculative local echo. WHEN defaults to `adaptive'
|
||||
(show predictions on slower links and to smooth out network glitches)
|
||||
and can also be `always` or `never'.
|
||||
|
||||
The MOSH_PREDICTION_DISPLAY environment variable controls this setting
|
||||
permanently and can adopt the same three values.
|
||||
|
||||
Even on `always', \fBmosh\fP will only show predictions when it is
|
||||
confident. This generally means a previous prediction on the same row
|
||||
of the terminal has been confirmed by the server, without any
|
||||
intervening control character keystrokes.
|
||||
|
||||
.TP
|

.B \-n
|
||||
Synonym for \-\-predict=never
|
||||
|
||||
.TP
|
||||
.B --family=\fIFAMILY\fP
|
||||
Force the use of a particular address family, which defaults to `inet'
|
||||
(IPv4), and can also be `inet6' (IPv6; requires IO::Socket::IP or
|
||||
IO::Socket::INET6).
|

||||
|
||||
.TP
|
||||
.B \-p \fIPORT\fP[:\fIPORT2\fP], \-\-port=\fIPORT\fP[:\fIPORT2\fP]
|
||||
Use a particular server-side UDP port or port range,
|
||||
for example, if this is the
|
||||
only port that is forwarded through a firewall to the
|
||||
server. Otherwise, \fBmosh\fP will choose a port between 60000 and
|
||||
61000.
|
||||
|
||||
.TP
|
||||
.B \-\-bind\-server={ssh|any|\fIIP\fP}
|
||||
Control the IP address that the \fBmosh-server\fP binds to.
|
||||
|
||||
The default is `ssh', in which case the server will reply from the IP
|
||||
address that the SSH connection came from (as found in the
|
||||
\fBSSH_CONNECTION\fP environment variable). This is useful for
|
||||
multihomed servers.
|
||||
|
||||
With \-\-bind\-server=any, the server will reply on the default interface
|
||||
and will not bind to a particular IP address. This can be useful if
|
||||
the connection is made through \fBsslh\fP or another tool that makes
|
||||
the SSH connection appear to come from localhost.
|
||||
|
||||
With \-\-bind\-server=\fIIP\fP, the server will attempt to bind to the
|
||||
specified IP address.
|
||||
|
||||
.TP
|
||||
.B \-\-no\-init
|
||||
Do not send the \fBsmcup\fP initialization string and \fBrmcup\fP
|
||||
deinitialization string to the client's terminal. On many terminals
|
||||
this disables alternate screen mode.
|
||||
|
||||
.TP
|
||||
.B \-\-local
|
||||
Invoke \fBmosh-server\fP locally, without using \fBssh\fP. This
|
||||
option requires the \fBhost\fP argument to be a local, numeric
|
||||
IPv4/IPv6 address. This option is useful for testing.
|
||||
|
||||
.SH ESCAPE SEQUENCES
|
||||
|
||||
The default escape character used by Mosh is ASCII RS (decimal 30).
|
||||
This is typically typed as \fBCtrl-^\fP or \fBCtrl-Shift-6\fP, on US
|
||||
English keyboards. Users of non-English keyboards may find it
|
||||
difficult or impossible to type the default escape character, and may
|
||||
need to change the escape character. See the description of
|
||||
MOSH_ESCAPE_KEY, below. In this description, the configured escape
|
||||
character is represented as \fBEsc\fP.
|
||||
|
||||
There are two slightly different modes for escape sequences, depending
|
||||
whether the escape character is printable or not.
|
||||
|
||||
If the escape character is a printable character, it must be prefixed
|
||||
with a newline, similar to \fBOpenSSH\fP. To send the escape character
|
||||
itself, type it twice. If the escape character is set to \fB~\fP,
|
||||
\fBmosh\fP will behave much like \fBOpenSSH\fP.
|
||||
|
||||
If the escape character is a non-printable control character, no
|
||||
prefix is used and the escape character is recognized at any time. To
|
||||
send the escape character itself, type the escape character, then its
|
||||
corresponding ASCII character (for \fBCtrl-^\fP you would type \fB^\fP,
|
||||
for \fBCtrl-B\fP you would type \fBB\fP).
|
||||
|
||||
The escape sequence to shut down the connection is
|
||||
\fBEsc .\fP. The sequence \fBEsc Ctrl-Z\fP suspends the client.
|
||||
Any other sequence passes both characters through to the server.
|
||||
|
||||
.SH ENVIRONMENT VARIABLES
|
||||
These variables are not actually interpreted by
|
||||
.BR mosh (1)
|
||||
itself, but are passed through to
|
||||
.BR mosh-server (1).
|
||||
They are described here for ease of use.
|
||||
|
||||
.TP
|
||||
.B MOSH_ESCAPE_KEY
|
||||
When set, this configures the escape character used for local
|
||||
commands. The escape character may be set to any ASCII character in
|
||||
the range 1-127. The variable must be set with a single literal ASCII
|
||||
character. Control characters are set with the actual ASCII
|
||||
control character, not with a printable representation such as "^B".
|
||||
|
||||
.TP
|
||||
.B MOSH_PREDICTION_DISPLAY
|
||||
Controls local echo as described above. The command-line flag
|
||||
overrides this variable.
|
||||
|
||||
.TP
|
||||
.B MOSH_TITLE_NOPREFIX
|
||||
When set, inhibits prepending "[mosh]" to window title.
