===== ssh config =====



==== use sock proxy ====

ssh actually supports sock proxy, just need to update ''ProxyCommand'' property for the host, it utilises ''nc'' to forward ssh connection. 

<file sshconfig ssh_config>
Host xxxx
    User xxxx
    Hostname xxxxx.com
    ProxyCommand=nc -X 5 -x localhost:1080 %h %p
</file>
