[ale] Dynamic DNS

[Jay Loden]

I would like to set up dynamic DNS.  I run my own DNS server for jayloden.com 
right now, and what I would like to do is find a way to set up a cron script 
on a couple of cable/dsl machines to, once an hour, fire off a script that 
somehow tells my jayloden.com server where they are and to update the dns 
accordingly.  (I have, for example, my mom's computer hooked in as 
mom.jayloden.com so I can ssh in to fix stuff, etc).

Right now, I use http://freedns.afraid.org 's system.  They have a url that 
you can grab with wget and it auto-updates the dns for the domain, and I just 
have a CNAME pointing to the afraid.org address.  

I would like to script it so I dont need afraid.org in the middle of this. 
Anyone have a suggestion how?  I was thinking that since I've been playing 
with pexpect, I might be able to use it to do some ssh scripting.  I would 
like to avoid a web front-end and do something through ssh or scp, or 
something a  little more secure than making a php/apache setup for this. 
However, all suggestions or ideas are welcome. 

I have total access to all the machines in question, so I can do crontabs, 
etc...anything I need to accomplish this neatly.
