sshuttle：一个使用ssh的基于VPN的透明代理

sshuttle 允许你通过 ssh 创建一条从你电脑连接到任何远程服务器的 VPN 连接，只要你的服务器支持 python2.3 或则更高的版本。你必须有本机的 root 权限，但是你可以在服务端有普通账户即可。

你可以在一台机器上同时运行多次 sshuttle 来连接到不同的服务器上，这样你就可以同时使用多个 VPN， sshuttle可以转发你子网中所有流量到VPN中。

在Ubuntu中安装sshuttle

在终端中输入下面的命令

1. <span class="pln">sudo apt</span><span class="pun">-</span><span class="kwd">get</span><span class="pln"> install sshuttle</span>

使用 sshuttle

sshuttle 语法

1. <span class="pln">sshuttle </span><span class="pun">[</span><span class="pln">options</span><span class="pun">...]</span><span class="pun">[-</span><span class="pln">r </span><span class="pun">[</span><span class="pln">username@</span><span class="pun">]</span><span class="pln">sshserver</span><span class="pun">[:</span><span class="pln">port</span><span class="pun">]]</span><span class="pun">[</span><span class="pln">subnets</span><span class="pun">]</span>

选项细节

-r, —remote=[username@]sshserver[:port]

远程主机名和可选的用户名，用于连接远程服务器的ssh端口号。比如example.com、testuser@example.com、testuser@example.com:2222或者example.com:2244。

sshuttle 例子

在机器中使用下面的命令：

1. <span class="pln">sudo sshuttle </span><span class="pun">-</span><span class="pln">r username@sshserver </span><span class="lit">0.0</span><span class="pun">.</span><span class="lit">0.0</span><span class="pun">/</span><span class="lit">0</span><span class="pun">-</span><span class="pln">vv</span>

当开始后，sshuttle会创建一个ssh会话到由-r指定的服务器。如果-r被丢了，它会在本地运行客户端和服务端，这个有时会在测试时有用。

连接到远程服务器后，sshuttle会上传它的（python）源码到远程服务器并执行。所以，你就不需要在远程服务器上安装sshuttle，并且客户端和服务器端间不会存在sshuttle版本冲突。
