Set Idle Timeout Interval for User Logins
SSH allows administrators to set an idle timeout interval. After this interval has passed, the idle user will be
automatically logged out.
Find and edit the following lines in /etc/ssh/sshd_config as follows:
ClientAliveInterval interval
ClientAliveCountMax 0
ClientAliveCountMax 0
The timeout interval is given in seconds. To have a timeout of 5 minutes, set interval to 300.
