The issue

I secured my server with knockd. So I need to knock on his door (ports) in order to start an ssh-session.

  • The usage
    • first I started a shell script that did the knocking
    • then I had to launch ssh

This was annyoing. There had to be a way to do this in one step. And it is. :-)

The solution

Add this to .ssh/config:

ProxyCommand /bin/bash -c '~/bin/knock.sh; sleep 1; exec nc %h %p'
