ssh

privilege escalation

By enabling pseudo-terminal with -t you can sudo into your root shell immediately.

$ ssh -t ansible@centos8 sudo -i
X11 forwarding request failed on channel 0
[root@centos8 ~]#

Socks Proxy

This will start and stop SOCKS proxies with SSH in a daemon like fashion.

Start a SOCKS proxy session

ssh \
    -f \ # Move ssh into background
    -N \ # Don't execute remote commands
    -M \ # Run ssh in "master" mode. This enables sending multiple commands over one session
    -S ~/.ssh/%C.sock \ # Control Socket for the session
    -D $PORT \ # Port for dynamic Port App Portforwarding aka SOCKS proxy port
    $SSH # SOCKS proxy Host

End the SOCKS proxy session

ssh \
    -S ~/.ssh/%C.sock \ # Control Socket for the session
    -O exit \ # Command send over Control socket
    $SSH # SOCKS proxy Host
