Kicking remote users

SpecialAgentR · 05-13-2007, 12:18 AM

Code:

[root@localhost ~]# who
root     tty1         May 11 11:39
rml0520  :0           May  9 09:13
rml0520  pts/1        May 12 13:17 (:0.0)
root     pts/1        May  9 10:02 (192.168.1.4)
root     pts/2        May 10 11:27 (192.168.1.4)

What would be the easiest way to kill both of the root users pts/1 and pts/2 that are connected through the 192 ip addresses? Thanks!

You could use ps or lsof to determine their PIDs and use kill to terminate their terminals.

man kill
man ps
man lsof
kill -l

or you can

Code:

ps aux | grep ssh
pkill [processnumber]

where [processnumber] is the number of the ssh process that the user is using to log into your system.

And if you want to keep a specific user out, as root you can run

Code:

passwd -l [username]

And then they cannot sign back in, because their password is locked. Unlock it with

Code:

passwd -u [username]

logically.
