Title: Custom Dymanic DNS
Post by: Rob A. on September 12, 2001, 10:30:34 PM

Can someone identify the Dynamic DNS client that is bundled with e-smith?  

I want to customize to work with a non-preconfigured Dynamic DNS provider (dyn.ca who use GNUDip).  Their docs indicate that supported clients are:
ez-ipupdate or a perl script that they provide.

What is the client the e-smith installs?
Ive read through the  dns2go mini how-to...Are there any other references?

Thanks,
Rob A.

The dynamic dns client is a shell script (actually, a group of them) in /sbin/e-smith/dynamic-dns.  I guess the perl script could be installed in place of the custom script, but I'm not sure how well that would work.

Thanks for the quick reply Dan -

I don't have access to an installed, running e-smith box.  Can someone tar up the directory contents and post somewhere?

TIA.

perl is fine. No problem whatsoever.

My only concern with the perl was dealing with the arguments being passed on the command line.  I'm sure it's possible in perl; I just don't have any idea how to do it.

anyone want to spell the "custom dynamic dns config" process/theory out a little more for a newbie?  like Rob A., i'd like to use dyn.ca (GNUDip based); they provide a command line perl file as a linux client. do i just put the body of that file in Dan Brown's script, & replace the shell scripts in in /sbin/e-smith/dynamic-dns?  anyone had any success here?

I've ended up putting my e-smith behind a smoothwall (linux) firewall
(www.smoothwall.org) in the DMZ zone, so I'm doing the dyn.ca
updates with the firewall box, and e-smith set up as server only.
