He critisises the idea because of an implementation he has found. When done properly, port knocking can add an extra layer of security and significantly improve the overall security of certain systems (the DSL connected private PC). A good implementation is e. g. Doorman <A HREF="http://doorman.sourceforge.net/" title="sourceforge.net">http://doorman.sourceforge.net/</a sourceforge.net> and I can only recommend it to protect your PC. Of course, having it disconnected, locked in a vault is still more secure than using port knocking.
