How do I stop my ssh tunnel when it is in the background?

Solution 1:

Find the PID with the ps command and send it a QUIT signal with the kill command.

Find the PID with:

ps -o pid,cmd | grep ssh

Send the QUIT signal with:

kill -QUIT <pid>

Solution 2:

The best solution I found is following to kill all the tunnels:

ps -o pid,cmd|grep "ssh -L"|grep -v grep|awk '{print $1}'|xargs kill

1. Gets id and command of all processes
2. Filter for ssh -L
3. gets the process id and kills it
