Howto hack ez-ipupdate / custom dyndns - Page 2

OldNerdGuy · #11 (**permalink**) 03-12-2005, 02:16 AM

I have two items. The first concerns ASL 5.200 and DYNDNS-Custom. I have this hack setup properly, and it was working great until I updated to 5.200. It then started out ok, but DYNDNS has since gone in the toilet. It will not run. When I try and start ez-ipupdate from an SU prompt, it appears we are running a very advanced version of ez-ipupdate...

ez-ipupdate Version 3.0.11b8
Copyright (C) 1998-2001 Angus Mackay.

I checked the ez-ipupdate web site, the latest version posted is 3.011b7. I have taken to doing manual updates of DYNDNS, for now. I would really, really like to have my Custom DNS back again.

Like I said, two points. In tracking this down, I found another Astaro Hacker Site: ASL Hackers FAQ
Check it out

Hello OldNerdGuy,

this is because of the nature of a hack ;-)
After you updated to ASL 5.2 /etc/dyndns.conf was overwritten with the dyndns configuration which is held in the ASL database and can only be seen in the GUI.
Therefore you should take your copy of dyndns.conf (like written in the ASL Hackers FAQ :-) and change it back - after that everything should work like before.

But you are right... the version looks strange compared with the infomartion at ez-ipupdate.com.

I've just been to h-ll and back with this one; glad I found this thread! Who would have suspected that Astaro would have backrev'd this module?

Anyway, here was my solution:

1. Go to http://rpmfind.net/linux/rpm2html/se...ry=ez-ipupdate and grab the latest (ftp://rpmfind.net/linux/SuSE-Linux/i...8-130.i586.rpm) with curl.
2. Run rpm -U ez-ipupdate-3.0.11b8-130.i586.rpm
3. Apply the dyndns-custom hack per 5.x

Hope this helps someone else. I was at my wits' end with this.

PS - Subsequent to the above, I tried picking up 3.0.11b8-142 from http://download.opensuse.org/distrib...8-142.i586.rpm, however, this seems to require libc.so.6 (GLIBC_2.4), so I didn't want to mess with things in case I ended up suffering under the law of unintended consequences... I'm not sure what may have been tightened up with the latest build. I'll have a look in the rpm to find out.

After installing v7 I found that the configuration of dyndns-custom is supposedly possible, but limits you to a single host name to update, so you can't have www.mydomain.com,mail.mydomain.com,mydomain.com updated by the firewall.
I dug deeper into the insides of the firewall and found that astart are now using command line parameters to set all the options for ez-ipupdate and no longer the dynsdns.conf file. It also appears that the dyndns startup script in the scripts directory although still there is not being used. This means that the old method of getting dyndns-custom working is no longer possible. Good one Astaro! If your going to add new functionality surely you would allow ALL options to be set not just the ones you think people might like.

@theRat:
Wouldn't the "Set wildcard record" option do what you need?

Abosultely not. The wildcard setting is only for the standard dyndns service, and does not exist within dyndns-custom.

So I guess your problem is that WebAdmin does not accept your input in the "hostname" field?

theRat · #18 (**permalink**) 03-07-2007, 11:11 AM

That would be it. I'm not sure how ez-ipupdate works when you are using command line parameters, but when you use a conf file you simply create a comma seperated list of all the hostnames. If you try this in webadmin it complains that the input is incorrect.

Hi Folks!

Last time I used ddclient I added it to the ifup scripts so it gets called whenever the interface gets back up. This way you get an update everytime (and only) when necessary. Some distros have ip-up.local scripts for that.
Running ddclient as a cron-job every 5 minutes is also possible of course, but sometimes even having to wait 5 minutes for the update to can be frustrating.

I haven't looked into the scripts, though. So I'm not sure if ddclient can be included.

Just my 2ct...

DiePlage,

That may work but you would have the usual problem of the script being reverted back to the original one every time an up2date was issued. In the case of v7 I think that might be a common occurence since the product appears very flakey at the moment. You do of course have this same issue with the ez-ipupdate hack that we have been using. It would just be nice if Astaro would actually allow you to set all the options of the underlying software they include. It surely isnt that difficult to add a few more options to a form and parse them into config files or scripts.
