So those interested in my remote DNS update CGI (via nsupdate), you can download it from my playground for now. Note that as usualy it comes without any warranty; there might be still security issues in there (but you don’t want to allow arbitrary users to access it anyway…) and so on, you know the drill.

The big plus of that app is that it doesn’t modify zone files, but just loads the current zone via the DNS protocol (zone transfer), and modifications are sent back to your DNS server via DNS, too (nsupdate, just like dhcpd does). That way it works very well remotely, is quite secure and reliable (no parsing of zone files involved, no reloading of your name server).

While it’s MIT-style licensed, I still appreciate improvements such as syntax checks for entered data (nsupdate does a bit, but not much).
