SSH Session to DPOD Disconnects Often

The following document is applicable to All-in-One DPOD appliance mode installation only.
In non-appliance installations, the operating system is under the responsibility of the customer, so the following procedure can only be used as an example.
Symptoms
SSH Sessions to DPOD servers disconnect after 5 minutes. This might become an issue when executing long-running system activities via SSH.
Cause
As part of the appliance hardening, a short timeout value (300 seconds) is set for the SSH session.
Resolution
To temporarily disable SSH timeout you may issue the following commands:
sed -i '/^.*ClientAliveInterval.*$/d' /etc/ssh/sshd_config
sed -i '/^.*ClientAliveCountMax.*$/d' /etc/ssh/sshd_config
service sshd restart
Once your long running activity has completed, issue the following commands to reinstate the short timeout settings:
sed -i 's/^.*ClientAliveInterval.*$/#ClientAliveInterval 300/' /etc/ssh/sshd_config
sed -i 's/^.*ClientAliveCountMax.*$/#ClientAliveCountMax 0/' /etc/ssh/sshd_config
service sshd restart
