RHEL: /etc/ssh/sshd_config "ClientAliveInterval" versus etc/profile "TIMEOUT" and "TMOUT"

Hi!

I would like to understand what is the difference of idle session timeout configured in /etc/ssh/sshd_config using parameter ClientAliveInterval versus the etc/profile TIMEOUT and TMOUT

what happens if i only configure the clientaliveinterval and not the other one, vice versa?

which is more secure, via sshd/config or via etc/profile?

thanks!

See the relevant sections in man sshd_config for details of those options.

Personally, I don't want an ssh session to automatically end for any reason if I can help it.

I've not seen TIMEOUT or TMOUT used for session control, so can't help you there.
