How would one kill a login on a machine? If for example I connected remotely and wanted to kill a open login on the machine I logged into. Thanks. -- B. L.

Just kill the user pid.. For example: root@pikachu:~ > w 9:33pm up 7:36, 2 users, load average: 0.40, 0.09, 0.03 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT anderson tty1 - 1:57pm 7:35m 48.61s 0.03s startx anderson pts/2 netuno.anderson. 9:29pm 19.00s 0.12s 0.05s -bash To kill the user logged on pts/2, who is logged as anderson: root@pikachu:~> ps -ax | grep pts The result: 1435 pts/2 S 0:00 login -- anderson So, just type kill -9 1435 Done!

Since the guy you want out is on a tty, you should have used ps -ax | grep tty here.

We don't know that.

...

Would it be the -bash that I'm looking for on 1030?

No, that is bljilek.

...

Why does it give a tty1 for mjilek and pts's for bljilek?

Because mjilek is logged in on the console, and the bljilek is logged in on a pseudo-terminal (x-term or telnet or something).

...

If there is a good place to read up on this kind of stuff where would that be? So I don't bug you all on this little stuff.

I would suggest a generic book on UNIX. Regards Ole Kofoed Hansen okh@post.cybercity.dk ICQ# 25773325 -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

Thank you. I think I've got it now. -- B. L.

Just kill whatever shell they're logging in using. For example, I'm logged into one of my computers (called devena) via telnet. I'm using the bash shell, so using the following (cut) output from 'ps aux', I know that I want to kill pid 3685 to shove off that user on ttyp0. So here I go and kill that login, and you can see that it works because I get thrown off the remote computer (yes, I killed myself...). devena:~ # ps aux USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND root 3684 3.2 10.7 1272 704 ?
