Well, I got Dynamic DNS for my box at home (on RoadRunner cable using
DHCP) working.  :)

For those of you who don't recall the thread, I wanted to set up my own
hostname for the box under my own domain (not dyndns.*). I did some
research, and found that TSIG with nslookup was the way to do it.

Basically, all you do is use dnssec-keygen to generate a shared key for
the update, configure your BIND server to allow updates from that key, and
then use the 'nsupdate' command with TSIG on the client to update the IP
address. I just added that to the ifup section of my dhclient-script file.

Really easy and simple. It's fun!

If you guys want more details, let me know.. I'll be happy to share, but
if nobody's interested, I won't bother typing it.  :)
