在长城宽带等某些垃圾宽带的网络环境下，通过 ssh 连接某些服务器经常会出现 timeout 的解决方法

ssh socks5 proxy

可在 .ssh/config 中配置以下命令，通过 ssh q 连接服务器。 HostName 为目标服务器 ip， -X 5 为 socks5 代理， localhost:6153 为 socks5 代理地址。

Host q
    HostName 47.240.33.24
    User root
    ProxyCommand            nc -X 5 -x localhost:6153 %h %p

与此方法类似的是，可以配置通过跳板机，在客户端直接访问内网服务器。jumper server 为跳板机，在正常情况下，处于内网环境的 target 服务器无法直接从客户端访问，需经过跳板机访问，此时，则可通过如下配置，在 Terminal 中运行 ssh target 访问跳板机后面的目标服务器。

Host target
    HostName 172.16.6.2
    Port 35000
    User root
    IdentityFile /Users/tonywang/target.key
    ProxyCommand ssh -q -W %h:%p jumperserver

Host jumperserver
    HostName 192.168.1.2
    Port 35000
    IdentityFile /Users/tonywang/js.key
    User root
