Problem With Who-u Command Output

V.V.KUMAR · #1 (**permalink**) 04-10-2005

I am Using SCo UNIX ver 5 and using korn shell. When I kill a process ID of user login, the process gets killed but the who -u command output shows the login name ,tty, and PID of the killed process along with other active process. The details of the killed process is listed on the who -u output and the idle time is also incremented even though no such process exists.This development took place 2 weeks before. I suspect that some file related to who output is not refreshed. I wish to know what files are altered on killing the process and how to rectify the same?

Are you sure that you are killing the login process of the user? If you are just killing a process run by the user, that does not mean that you are logging the user out.

If you want to kill a user's session, you have to kill the login shell. These can be seen by using the 'ps' command:

Code:

ps -ef | grep -e -sh -e -csh -e -ksh |grep -v grep

Then you can kill the -<shell> processes. Check if this works.

And also, (in solaris) the /var/adm/utmpx file is used by who to check logged in users. If you are using a different os, just check the man page for utmpx (it will be present in almost all of 'em).

or this ... (change "auser" to actual username of user) ...

Code:

kill -9 `ps -ef|awk '/\-.sh/ && /auser/ {print $2}'`
