Is there a list of RFC's on univercd which can be accessed during the lab? I have seen in some lab's reference to RFC in which if you didn't know what they were talking about you were just hosed... and there are way too many RFC's to memorize each one.

Phew. I ran out of memory space long ago. Information I use often eg tcp/udp
ports, out of repeated use, somehow managed to find some memory location
configured for sticky learning. I doubt I will get to configure DHCP
options that often, especially since most dhcp servers give you nice and
friendly (translation english) option names when configuring them :)
Thanks Antonio.
