I'm going to try this out. Sure looks great! Although, the real space saver would be to have a tiny libopenssl which is the hugh package needed.: ) I am going to try another type of solution (e.g. through restricted ssh access on the DNS server, with only nsupdate command allowed) so I don't have to install nsupdate & libopenssl on the wrt54gl. I'll keep you posted, Cheers, Ghantoos PS: I just added the "subscribe to comment" so you can choose to receive an email when a reply is posted. Thanks for your comment Dean!

It only does public key SIG(0) updates (public keys for all, yay). There's another one I haven't tried: http://ipupdate.sourceforge.net/ which does TSIG. An orthogonal issue is that you can incorporate a hotplug script that will get called when PPP is brought up instead of a cronjob. There's also a slightly more accurate (in my opinion) hereustic for determining the IP: by route instead of "whatever isn't localhost". See the dudders .ipk although it would work for nsupdate too.
