No kidding. Another pet peeve of roughly the same category: when you enable IPv6, telnet is automatically open to the world (using v6), even if you have disabled v4 telnet with an access-list. The vendor refused to believe this is a problem, so I'm waiting for v6 deployment to get really started before writing bugtraq. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
