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.If you need to perform long-running system activities,

Resolution

To temporarily disable SSH timeout you may issue the following commands:

Code Block
languagebash
themeRDark

...

...

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:

Code Block
languagebash
themeRDarktitleEnable SSH timeout
sed -i 's/^.*ClientAliveInterval.*$/#ClientAliveInterval 300/' /etc/ssh/sshd_config
sed -i 's/^.*ClientAliveCountMax.*$/#ClientAliveCountMax 0/' /etc/ssh/sshd_config
service sshd restart
