Here’s how to keep your SSH timeout alive for a longer period.
Edit /etc/ssh/sshd_config. Adjust interval and count max.
ClientAliveInterval 1200 ClientAliveCountMax 3 |
ClientAliveInterval is set to 1200 and ClientAliveCountMax is set to the default which is 3. This means unresponsive SSH clients will be disconnected after approximately 3600 seconds or 1 hour.
