SSH daemon like widely used Openssh's sshd can send "keep-alive" packets. See its man page for the settings details.
I hope it helps. Personally, I see no reason for considering it as a "securing" way. To do it, I'd better set a shorter rekeying period. It is number of packets to be sent before next re-keying handshake negothiated. Good value is 1000 or about. Another secured way is "public key" based authentication. Local key can be protected with password. As of session timeout, it's good when set to tens minutes or more, not seconds, or it brings more headache than safety. |
