Hi Dave,

That's an easy challenge to answer:
 RFC 862 - ECHO Protocol
 RFC 863 - DISCARD Protocol
 RFC 864 - CHARGEN Protocol

Those protocols are not crappy ;-)
But, you can do nasty things with them...

I can quickly identify LOTS of crappy protocols running over
TCP/IP and UDP/IP.

Give me an example of one you think is *not* crappy:-)

The downside is that this can break crappy protocols (or
even normal protocols in the case of a misconfigured firewall).
