1, Edit sshd_config

vi /etc/ssh/sshd_config

2, Edit ClientAliveInterval and ClientAliveCountMax

ClientAliveInterval 600
ClientAliveCountMax 3

this will give you 30 minute idle time (3 x 600 seconds) and you don’t need to reconnect your application (SCP, Putty) every few minutes.

3, Restart sshd:

/etc/init.d/sshd restart
