SSH reference

To automatically proxy connections from one machine to another automatically, add this to ``~/.ssh/config`:

Host target target.example.com
    ProxyJump proxy.example.com

To proxy connections only temporarily:

ssh -J proxy.example.com target.example.com

To forward a local port to a remote one:

ssh -L <localPort>:127.0.0.1:<remotePort> <remoteHost>
ssh -L <localPort>:<remoteHost>:<remotePort> <proxyHost>
