As part of the appliance hardening, a short timeout value (300 seconds) is set for the SSH session.
If you need to perform long-running system activities, you may issue the following commands:
disable ssh disconnect
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
