UNIX for Dummies Questions & Answers

hi, we can set something such that if the user has been idle for a while, it will auto disconnect. where to do so? thanks

if my guess is right, you are looking for a way to
log off idle users? right

you could write a script to log off idle users

here is a korn shell script that could log off users that is idle for more than 60minutes or 1 hour, this script log off idle user apart from root users and users log on to the console

#!/usr/bin/ksh


who -u | sed -e "s/\./0/" -e "s/://g" |awk '$6 > 60 {print $1" "$2" "$7}' | \
while read -r NAME TER PID



do

if [ "$NAME" = "root" ]
then
echo " Idle root users can not be log off " >/dev/null
else


if [ "$TER" = "console" ]
then
echo "user logged in at the console can not be log off " >/dev/null
else

kill -9 $PID

fi
fi
done

this is terrific!

pls tell me where to put file to and how and when to execute this file.

thank you very much.

then this script must be running all the while?
but in the resource point of view, doesnt it take up resources?
thanks

if this is for solaris you can set the TMOUT variable like this.

# TMOUT=900# export TMOUT

the 900 is in seconds
set this prameter in /etc/profile or in each users home directory in .profile file.

You may want to write your own script - I'm trying to stay objective, but that script is flawed.

First off, those echo statements are being redirected to /dev/null. What's the point?

And it uses kill -9 right away, which is a Bad Thing if your users have anything running or any processes backgrounded. Also, I've seen problems with killing off a user very harshly like that that can mess up their entries in w or who, saying they exist even though they don't. You'll also end up with orphaned processes that way...

One alternative that I've seen is idled:

It's a little cleaner than crashing around in the dark "kill -9"'ing processes automatically.

in solaris, we can do the below

# TMOUT=900# export TMOUT

the 900 is in seconds
set this prameter in /etc/profile or in each users home directory in .profile file.

is there any equivalent in ibm aix or hpux. thanks
