You can configure any Linux system to automatically log users out after a period of inactivity. Simply login as the root user and create a file called /etc/profile.d/autologout.sh, enter::
# vi /etc/profile.d/autologout.sh Append the following code: TMOUT=300 readonly TMOUT export TMOUT Save and close the file. Set permissions: # chmod +x /etc/profile.d/autologout.sh Above script will implement a 5 minute idle time-out for the default /bin/bash shell. You can also create tcsh version as follows: # vi /etc/profile.d/autologout.csh Append the following code: set -r autologout 5 Save and close the file. Set permissions, enter: # chmod +x /etc/profile.d/autologout.csh Dealing with ssh clients SSH allows administrators to set an idle timeout interval. After this interval has passed, the idle user will be automatically logged out. Open /etc/ssh/sshd config file, enter: # vi /etc/ssh/sshd config Find ClientAliveInterval and set to 300 (5 minutes) as follows: ClientAliveInterval 300 ClientAliveCountMax 0 Save and close the file. Restart sshd: # service sshd restart
