assh

assh

概述

一个透明的包装器，为SSH增加了对正则支持，别名，网关，动态主机名， graphviz ， json输出， YAML配置等的支持。

lib–ssh将assh作为代理人；这意味着它与：

• SSH
• SCP
• rsync
• git
• 桌面应用程序取决于lib-ssh或ssh （即，塔，atom.io，SSH隧道经理）

有关具体示例，请参见第三方集成

特征

配置功能

• 正则支持
• 别名gate – > gate.domain.tld
• 网关– >透明的SSH连接链
• 包括：在多个文件中的拆分配置
• 本地命令执行：最后是remoteCommand的逆转
• 模板：相当于主机，但您无法直接连接到模板，非常适合继承
• 继承：从主机或模板中制作主机继承
• 可变扩展：从环境中解析变量
• 智能proxyCommand ：使用netcat和socat作为默认后备时，RAW TCP连接
• 费率限制：配置每主机或全球利率限制
• JSON输出
• GraphViz ：主机的GraphViz重复

使用命令行的网关

assh可以将ProxyCommand与Openssh透明的NetCat功能一起使用，也可以使用扩展配置的痛苦。

使用hostb作为网关连接到hosta 。

    Y-> b
    b-> a

$ ssh hosta/hostb
user@hosta $

相当于ssh -o ProxyCommand=\"ssh hostb nc %h %p\" hosta

使用hosta作为网关连接到hostb ，使用hostc作为网关。

$ ssh hosta/hostb/hostc
user@hosta $

等效于ssh -o ProxyCommand=\"ssh -o ProxyCommand=\'ssh hostc nc %h %p\' hostb nc %h %p\" hosta

使用配置文件中的网关

您可以定义Openssh的“带有NetCat的ProxyCommand”功能，具有简单的语法，更高级的工作流和独特的后备功能。

让我们考虑以下assh .yml文件

 hosts :
  hosta :
    Hostname : 1.2.3.4

  hostb :
    Hostname : 5.6.7.8
    Gateways : hosta

  hostc :
    Hostname : 9.10.11.12
    Gateways : hostb

  hostd :
    Hostname : 13.14.15.16
    GatewayConnectTimeout : 2
    Gateways :
    - direct
    - hosta

• ssh hosta > ssh 1.2.3.4
• ssh hostb b-> ssh -o ProxyCommand=\"ssh hostb nc %h %p\" hosta
• ssh hostc > ssh -o ProxyCommand=\"ssh -o ProxyCommand=\'ssh hostc nc %h %p\' hostb nc %h %p\" hosta
• ssh hostd – >
  • assh将尝试进入ssh 13.14.15.16
  • 然后，在ssh -o ProxyCommand=\"ssh hostd nc %h %p\" hosta
  • 此方法使您可以在可能的情况下具有最佳的性能，但是如果您不在公司之外，请确保您的命令可以正常工作

引擎盖功能下

• 在需要时自动再生~/.ssh/config文件
• 检查父进程确定日志级别（如果使用ssh -vv ， assh将在调试模式下自动运行）
• 自动创建ControlPath目录，因此您可以在ControlPath选项中使用SLASHES ，可以使用ControlMasterMkdir: true配置。

钩子

事件

beforeconnect

在assh试图连接到远程SSH端口之前， BeforeConnect被称为。

注意：每个SSH连接将调用BeforeConnect ；如果您使用多个网关，则将为每个网关调用，直到一个人成功连接。

Golang模板变量的示例：

 // Host: http://god*o*c.org*/moul.io/assh/pkg/config/#Host
{{. Host . Name }}                                  //  localhost
{{. Host . HostName }}                              //  127.0.0.1
{{. Host . Port }}                                  //  22
{{. Host . User }}                                  //  moul
{{. Host . Prototype }}                             //  moul@127.0.0.1:22
{{. Host }}                                       //  {\"HostName\":\"localhost\",\"Port\":22\",\"User\":\"moul\",\"ControlPersist\":\"yes\",...}
{{ printf \"%s:%s\" . Host . HostName . Host . Port }}    //  localhost:22 

连接

一旦assh连接到远程SSH端口， OnConnect就会立即调用。

注意： OnConnect不知道身份验证过程，并且将始终提出。

Golang模板变量的示例：

 // Host: http://god*o*c.org*/moul.io/assh/pkg/config/#Host
{{. Host . Name }}                                  //  localhost
{{. Host . HostName }}                              //  127.0.0.1
{{. Host . Port }}                                  //  22
{{. Host . User }}                                  //  moul
{{. Host . Prototype }}                             //  moul@127.0.0.1:22
{{. Host }}                                       //  {\"HostName\":\"localhost\",\"Port\":22\",\"User\":\"moul\",\"ControlPersist\":\"yes\",...}
{{ printf \"%s:%s\" . Host . HostName . Host . Port }}    //  localhost:22

// Stats: http://godoc.o***rg/moul.io/assh/pkg/commands/#ConnectionStats
{{. Stats . ConnectedAt }}                           //  2016-07-20 11:19:23.467900594 +0200 CEST 

OnConnectError

当assh未能打开新的TCP连接时，请使用OnConnectError 。

Golang模板变量的示例：

 // Host: http://god*o*c.org*/moul.io/assh/pkg/config/#Host
{{. Host . Name }}                                  //  localhost
{{. Host . HostName }}                              //  127.0.0.1
{{. Host . Port }}                                  //  22
{{. Host . User }}                                  //  moul
{{. Host . Prototype }}                             //  moul@127.0.0.1:22
{{. Host }}                                       //  {\"HostName\":\"localhost\",\"Port\":22\",\"User\":\"moul\",\"ControlPersist\":\"yes\",...}
{{ printf \"%s:%s\" . Host . HostName . Host . Port }}    //  localhost:22

// Error
{{. Error }}                                      //  dial tcp: lookup localhost: no such host 

OnDisconnect

当assh插座关闭时， OnDisconnect被称为。

警告：如果关闭SSH连接时看不到通知，则可能配置了ControlMaster ； OnDisconnect与ssh程序没有链接，而是与其插座相关联，即使退出ssh程序也可能会活着。

Golang模板变量的示例：

 // Host: http://god*o*c.org*/moul.io/assh/pkg/config/#Host
{{. Host . Name }}                                  //  localhost
{{. Host . HostName }}                              //  127.0.0.1
{{. Host . Port }}                                  //  22
{{. Host . User }}                                  //  moul
{{. Host . Prototype }}                             //  moul@127.0.0.1:22
{{. Host }}                                       //  {\"HostName\":\"localhost\",\"Port\":22\",\"User\":\"moul\",\"ControlPersist\":\"yes\",...}
{{ printf \"%s:%s\" . Host . HostName . Host . Port }}    //  localhost:22

// Stats: http://godoc.o***rg/moul.io/assh/pkg/commands/#ConnectionStats
{{. Stats . ConnectedAt }}                           //  2016-07-20 11:19:23.467900594 +0200 CEST

{{. Stats . AverageSpeedHuman }}                     //  3.4kb/s 

beforeconfigwrite

在assh重写~/.ssh/config文件之前， BeforeConfigWrite被调用。

Golang模板变量的示例：

{{. SSHConfigPath }}                               // ~/.ssh/config

执行驱动程序

Exec驱动程序使用Golang的模板系统执行shell命令

用法： exec <binary> [args...]

 defaults :
  Hooks :
    OnConnect : exec echo \'{{.Host}}\' | jq .
# executes: `echo \'{\"HostName\":\"localhost\",\"Port\":\"22\",\"User\":\"moul\",\"ControlPersist\":\"yes\",...}\' | jq .
# which results in printing a pretty JSON of the host
# {
#   \"HostName\": \"localhost\",
#   \"Port\": \"22\",
#   \"User\": \"moul\",
#   \"ControlPersist\": \"yes\",
#   ...
# } 

assh@42.am
# send an email with the connection prototype\”>

 defaults :
  Hooks :
    OnConnect : exec echo \'New SSH connection to {{.Host.Prototype}}.\' | mail -s \"SSH connection journal\" m+ assh @42.am
# send an email with the connection prototype 

 defaults :
  Hooks :
    BeforeConfigWrite : exec cp {{.SSHConfigPath}} {{.SSHConfigPath}}.backup
# make a copy of ~/.ssh/config before being rewritten 

 defaults :
  Hooks :
    AfterConfigWrite : \' exec echo \"# date: `date`\" >> {{.SSHConfigPath}} \'
# Append a comment with the compilation date to the generated ~/.ssh/config file 

 defaults :
  Hooks :
  AfterConfigWrite : \' exec cat /path/to/my/provider/generated/.ssh/config >> {{.SSHConfigPath}} \'
# Append another .ssh/config file to the generated .ssh/config file

exec命令正在阻止，计划了一个新的背景任务驱动程序。目前，您可以在这样的背景中运行一份工作：

 defaults :
  Hooks :
    OnConnect :
    - exec sleep 60 &
# execute the `sleep 60` command in background (non-blocking)
# if you quit your ssh connection, the process will continue in background. 

写驱动程序

写驱动程序使用Golang的模板系统来写入数据

用法： write <line:string...>

 defaults :
  Hooks :
    OnConnect :
    - write New SSH connection to {{.Host.Prototype}}.
# writes: \"New SSH connection to moul@127.0.0.1:22.\" on the terminal on connection 

 defaults :
  Hooks :
    OnDisconnect :
    - \" write SSH connection to {{.Host.Name}} closed, {{ .Stats.WrittenBytes }} bytes written in {{ .Stats.ConnectionDuration }} ({{ .Stats.AverageSpeed }}) \"
# writes: SSH connection to localhost closed, 40 bytes written. 

通知驱动程序

通知驱动程序使用Golang的模板系统打开桌面通知。

• Mac OS X ：内置支持
• Linux ：取决于GNOTIFIER
• Windows ：不支持
• BSD ：不支持

用法： notify <line:string...>

 defaults :
  Hooks :
    OnConnect : notify New SSH connection to {{.Host.Prototype}}. 

 defaults :
  Hooks :
    OnDisconnect :
    - \" notify SSH connection to {{.Host.Name}} closed, {{ .Stats.WrittenBytes }} bytes written in {{ .Stats.ConnectionDuration }} ({{ .Stats.AverageSpeed }}) \" 

配置

assh现在管理~/.ssh/config文件，请注意备份~/.ssh/config文件。

~/.ssh/ assh .yml是一个包含：

• 一个hosts字典，包含多个主机定义
• 一个包含全局标志defaults部分

# Log internal information to a file
– exec printf \'{{.}}\’ | jq . >> ~/.ssh/last_connected_host.txt

# Alert me with a Desktop notification
– notify New SSH connection to {{.Host.Prototype}} at {{.Stats.ConnectedAt}}

# Write the host prototype to the terminal stderr
– write New SSH connection to {{.Host.Prototype}}

OnDisconnect:

安装

使用GO获取最新版本（推荐方法）：

go install moul.io/ assh /v2@latest

注意：使用GO1.7或更高版本测试

使用Homebrew（Mac OS X）获取最新发布的版本：

brew install assh

构建最新版本

brew install assh --HEAD

获取发布版本：https：//github.com/moul/assh/releases

使用ASDF-VM安装：

assh
asdf install assh latest
asdf global assh latest\”>

asdf plugin add assh
asdf install assh latest
asdf global assh latest

注册包装器（可选）

要在使用高级模式匹配时提高经验，请在.bashrc / .zshrc / config.fish的末尾添加以下内容：

 alias ssh= \" assh wrapper ssh -- \"

此步骤不是强制性的，但强烈建议。

注意： ssh不了解高级模式；为了绕过这一限制， assh维护已知主机的列表，并使用所有这些已知的已知主机再生~/.ssh/config 。

如果没有包装器，则首次连接到新主机时将过时的~/.ssh/config风险，您需要再次启动该命令。

使用包装器， ssh将始终使用更新的~/.ssh/config文件调用。

入门

1. 备份您的旧~/.ssh/config ： cp ~/.ssh/config ~/.ssh/config.backup
2. 创建一个新的~/.ssh/ assh .yml文件
3. 运行assh config build > ~/.ssh/config以验证您的~/.ssh/ assh .yml文件的语法，并自动构建您的~/.ssh/config文件
4. 你准备好了！
