Is it possible??

Hi
you can use the environment variable TMOUT. You can set it in /etc/profile

for ksh export TMOUT=100 ( per sec. )

and i think in csh is setenv TMOUT=100

hope that i help

Hi Renato,

You may set the variable TMOUT to the desired amount of seconds that you wish to limit, and put such a definition in the /etc/profile.

#vi /etc/profile
and add the following line:

export TMOUT=60

This example for a timeout set to 60 seconds of unactivity.

This works well, however I suggest you make TMOUT readonly otherwise users will modify the value to avoid the timeout. Also TMOUT is in seconds, so you might want it to be a little larger; we user 1800 (30 Minutes).

TMOUT=1800 readonly TMOUT
export TMOUT
