Off of another message..

I just tested land.c on a cisco 753 router running version 4.0 of the os.
It DID freeze the router when I hit it on port 23.  The router wasn't able
to reach the internal lan or the wan and some lights on the front of the
router were frozen also.  I couldn't ping or telnet to the router, the
only way to restart it is a hard reboot.
