Thanks for the update Colin, I was unaware that it had changed. I'm wondering if it would be helpful to at least display this in the help files for users looking for the option and / or possibly log it to syslog that the option is now depreciated?
Eg: man: "Keepalive: Depreciated, please see TCPKeepAlive below" syslog: "[OpenSSH] Option KeepAlive is now depreciated, please read the help files and replace this with TCPKeepAlive". -- openssh-server: Manual page sshd_config is missing KeepAlive description https://launchpad.net/bugs/50702 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
