Killing an SSH Session

chatmasta · 07-02-2005, 05:42 PM

How can I kill somebody's SSH session (as root)? I'm a noob to killall. When I list the processes, there is USR1, USR2, and USR3. But:

Code:

saffron:~# killall USR2
USR2: no process killed

You need the name of the process, but killall is a BAD solution to killing a single ssh login. The best way (if you want to do this) is to use "ps" to find the PID of their root bash session (listed as -bash, usually) and then kill -9ing it.

OK Lets See!!

#ps -aux | grep ssh
then in the left side there will be pid like 4635 or what ever
#kill -9 pid
hope this helps you

It's hard with ps to see who is connected to who..

Try netstat -tanp and locate the ESTABLISHED connection that matches.
The PID to kill is in the right hand column.
Don't use kill -9 if you can avoid it. It doesn't always allow the daemons to clean up temp files, locks etc. Use kill -TERM PID or kill -15 PID

PS will allow you to see the username. I guess it depends on what you want to kill by: the user's id, or the remote host of the connection.

Check who is logged in

Code:

last |grep "logged in"

Check <PID> for this user

Code:

ps -aux | grep ssh | grep pts/

Kill SSH user

Code:

kill -9 <PID>
