SSH timeout interval

A user can log in to the server via ssh, and you can set an idle timeout interval to avoid unattended ssh session. Open sshd_config and make sure following values are configured:
ClientAliveInterval 300
ClientAliveCountMax 0


You are setting an idle timeout interval in seconds (300 secs == 5 minutes). After this interval has passed, the idle user will be automatically kicked out (read as logged out).
