"Port Knocking" For Added Security

Jeff writes "The process of Port Knocking is a way to allow only people who know the "secret knock" access to a certain port on a system. For example, if I wanted to connect via SSH to a server, I could build a backdoor on the server that does not directly listen on port 22 (or any port for that matter) until it detects connection attempts to closed ports 1026,1027,1029,1034,1026,1044 and 1035 in that sequence within 5 seconds, then listens on port 22 for a connection within 10 seconds. The web site explains it in some detail, and there is even an experimental perl implementation of it that is available for download. I can't think of any easy ways you could get around a system using this security method - let alone even know that a system is implementing it. Another article on port knocking is here."

    If you ask me, port knockers are all a bunch of fart knockers.

    The Ninnle Linux distro has had this feature for ages - really useful on servers and other scenarios where maximum security is paramount.

    Most, if not all, gays have a hetero mode. Normally they are configured to ignore all persons with genitals other than theirs. But they have a hetero mode where they suck all genitals.

    It is trivial to suck other genitals on the same gay.

    Would this have any relation to fart knocking? Fart knocker.
