To ensure the SSH session does not time out, you would want to edit the /etc/ssh/sshd_config file to ensure these settings are in place:

ClientAliveInterval 30 TCP
KeepAlive yes
ClientAliveCountMax 99999

After making those changes, please be sure to restart your SSH service using the command:

service sshd restart

If you only want to do it on a per session basis, you could just append this flag to your SSH command:

-o ServerAliveInterval=100

Hope it helps!

Hi,

Shouldn't it instead be

ClientAliveInterval 30
TCPKeepAlive yes
ClientAliveCountMax 99999
