Debian as a DDNS Server
I've done some digging around but haven't found exactly what I'm looking
Basically I have a Debian server with a static IP address (and several
domains registered on it).
I also have a system with a dynamic domain on a completely different
What I would like to do is set up the system with the static IP address
to be a DDNS server, ala dyndns.org or similar.
The router on the dynamic ip system can be set up to automatically
notify someone when the ip changes, so that's not a problem.
What do I need on the static IP system to do this? Are there packages
for Debian, or will I need to write my own?
