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'
