hi folks,

i run djbdns at a couple of sites and while it does not have any means
to dynamically update DNS information (that's *not* an advantage of
BIND, just look at their implementation), the datafile makes
programmed edits really simple.

I want to give my users the possibility to change their zone entries
(mainly for dynIP DNS). however, i would like to do so in a very
secure way.

let's say everything works on the server, all i need is a method to
authenticate a user and upon successful authentication, pass the IP
s/he used for the authentication on to a script that takes care of the

There exists a fake POP3 server that does exactly this (it always
serves an empty mailbox), but it's cleartext. I would like at least
SSL, and asymmetric authentication with certificates would be the

i don't really have time to implement this myself, so i am wondering
if you guys know of such a tool. I have considered GPG-signed email,
but that strikes me as a little cumbersome for the task, and it
doesn't guarantee timely changes. I've thought about an SSL website
with a form that also exposes a simple interface via HTTP, and while
i like this approach, i don't think i am capable enough to implement
a CGI securely, at least not with the time I have at hand. is there
already such a system?

any thoughts are greatly appreciated!
