SSH _MUST_ be configured with an Active Server Alive Maximum Count set to 900 or less.
Setting the Active Server Alive Maximum Count to 900 (second) will log users out after a 15-minute interval of inactivity.
NOTE: /etc/ssh/ssh_config will be automatically modified to its original state following any update or major upgrade to the operating system.
Fix:
/usr/bin/sed -i.bak 's/.*ServerAliveInterval.*/ServerAliveInterval 900/' /etc/ssh/ssh_config
Parameter:
[900]
Technical Mechanism:
/usr/bin/sed -i.bak 's/.*ServerAliveInterval.*/ServerAliveInterval 900/' /etc/ssh/ssh_config
