cat ~/.ssh/config

    ProxyCommand ssh -q -W %h:%p fenghong.tech

In addtion . some ssh client do not support -W . you can use this command instead. by the way , window has no nc. so, this is a linux way~

    ProxyCommand  ssh proxyuser@proxy.machine nc %h %p 2> /dev/null

Use socks5 to proxy .

On mac / ubuntu / centos

$ cat ~/.ssh/config 
Host github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa
    ProxyCommand nc -v -X 5 -x 127.0.0.1:1080 %h %p
