RHEL-06-000231 - The SSH daemon must set a timeout count on idle sessions.

Information

This ensures a user login will be terminated as soon as the 'ClientAliveCountMax' is reached.

Solution

To ensure the SSH idle timeout occurs precisely when the 'ClientAliveCountMax' is set, edit '/etc/ssh/sshd_config' as follows:

ClientAliveCountMax 0
