How can I close an ssh tunnel?

Question

I have opened an ssh tunnel with lucas-MacBook-Pro:~ donbeo$ ssh -D 8080 -f -C -q -N [email protected]

How can I close it now?

Answer 1

Find the ssh tunnel's process id running on a specific port:

ps aux | grep <port number>

and kill the process:

kill -9 <process id>

Answer 2

You can kill the ssh process like others with

kill -9 $PID

You can find ssh session process ID with

pgrep ssh

Answer 3

You have to type

~.

to exit/close the ssh connection. I think

exit

also works.
