script for logging off users who are idle

[John Jimenez]

Pat,
Yes if you would not mind, could you e-mail it to jimenez-j@iehp.org?

Hi John,

I don't know scripts to logout users who are idle.
Anyway a possible solution is keepalive parameters.

ndd -h | grep -i keepalive

You will see more details by

ndd -h

Hope this helps you.

Best regards,
Fabio

Thanks for the help, But I will have to find another way. The sessions sitting in the app never go into an idle state even though they are not doing anything.

I do not know the nature of your application but when they run, i.e., not sit idle on the screen, if they accumulate CPU time for the shell they are running under, you can collect this information by the help of ps and awk commands and decide who is idle and who is depending on the accumulated cpu time per process. Just a wild idea.

Well, if you are NOT at a shell prompt (which eliminates the ability to use autologout in tcsh for example), then I suggest a C program that runs as a background system process (daemon), reads the utmp file to get the tty for each user logged into the system, and then do a stat() on the device file to get the last timestamp (indicating activity on the tty). I think this is how the "idle" output of the "w" command is determined. I already have a program written in "C" to "watch" users who log in and out. With some work, it could be adapted to look for idle users, and then kill the session. It has not been tested on HP-UX greater than 11.0 though. Let me know if you are interested. The project spans more than one "C" file though...so I can't really post it here. I could possibly make these additions in my spare time, but I can't guarantee how long it would take for me to finish. :-) I hope that you or someone else can use the info that I provided above to write your own version.
:-) Good luck!

Tom,

I am the Admin here. Max, who is the programmer, is not here today. Would it be to much to ask you to send me what you have already. I am sure that he can modify it accordingly. If so my email adress is Jimenez-J@iehp.org

Thanks again,
John

Hi John try "idled", it is a freeware with C source, your programer can modify and compile it according to your company needs.

John,

I took a quick look at "idled" and it actually seems to do exactly what you need. So take a look. If you have trouble getting it to work or still need me to send you the code that I have (which would need modification to do what you need), let me know. Take care.

Something to Add to Tom Schroll, If I am correct, after you download the source code the default make file is set to be used on SUN OS, you will need to comment that section and uncomment the HP section. after that you can compile and install the software.

Thanks

Try this:

#!/bin/ksh
who -u | cut -c 1-10,38-50 | egrep "[12][0-9]:|old" > /var/tmp/current
for IDLE_USR in `cat /var/tmp/current | awk '{print $3}'`
do
# kill -9 $IDLE_USR
echo $IDLE_USR
done


This will kill any login shell where the user has not typed anything for 10 hours or more.
When you've tried it out and are happy that it is choosing the right processes to kill, remove the comment from the kill line and delete the echo line.
