My development and testing webserver is used by over 100s of users. These users login from Windows XP, Linux, Mac OS X system via ssh. How do I set or automatically log users out after a period of inactivity under CentOS Linux server to improve server security and save some resources?
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::

# chmod +x /etc/profile.d/autologout.cshDealing 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:
Find ClientAliveInterval and set to 300 (5 minutes) as follows:
# vi /etc/ssh/sshd configFind ClientAliveInterval and set to 300 (5 minutes) as follows:
ClientAliveInterval 300 ClientAliveCountMax 0
Save and close the file. Restart sshd:
# service sshd restart
