Namecheap dynamic dns Not Updating

Trel

How exactly do you have the Namecheap host setup in the DynDNS settings?

Disable: unchecked
Service: Namecheap
Hostname: @.my.domain.co
MX: <blank>Wildcard: unchecked
Username: <blank>Password:</blank></blank>

I tried on Sunday to change it to having the "wildcard" box checked.
There doesn't seem to be any change.

If your post is not "too old" there should be a "Modify" link on it.

It was too old then. I see a modify link on my newer one. I hate double posting >.>

I also have this issue. So what I did as a workaround is SCP ddclient (http://sourceforge.net/apps/trac/ddclient/) onto my pfsense box. It is a perl script, so no need to have a specific version compiled for freebsd/x86. I then updated the config for namecheap, and it works great :)

Its a hack, but it works.

Trel

I cannot do that sadly. I need to use the built in function for this.

It may be due to how the update URL gets formed when using the "@" record.

Can you try this with an actual hostname under the domain rather than the @ record?

That's not possible with the domain in question. I could try adding one, but I can't until tonight.
(and ultimately it IS the @ record that needs to be updated, so even if this is the issue, I need it to work for the @ records.)

jimp

Yes, I understand that, I'm just trying to make sure it's not a problem with your account in general, but one specific to the @ record handling.

I don't have a free @ record handy that I can tinker with at the moment, but I can try to free one up. All my Namecheap dyndns entries are traditional host.domain.tld format, no @ records.

I'll see if I can make an additional one during my lunch.

jimp

I was able to free up an @ on one of my domains for testing, and it worked for me. No errors, and the @ record updated as expected.

I used the @.domain.tld format and it updated as expected using the dyndns access key for the domain.

Maybe try to re-enable DynDNS for your domain and then use the new auth token they generate when it resets.

Oh, and that was on a 2.1 snapshot from Thursday.

I'm not on a snapshot. I'm using the latest stable.

I pulled up a 2.0.3 VM and tried it there, worked the same, no problems. I even edited the IP in Namecheap's control panel to something bogus, then removed the cached IP from the pfSense VM and made it update again, worked fine.

Does it work if the domain is one deeper, @.sub.domain.com?
(Also, how can I force it to update for testing)
(And you're leaving the username blank, right?)

jimp

Username blank, yes.

You can force an update by removing the cache file from /conf and then saving on the page.

A subdomain is not considered an @ record in their DNS that I'm aware of. It would just be sub.domain.com where sub is just a hostname in that context.

IIRC their DNS does not split that into separate "true" zones that would contain an @ record.

sub.domain.com is what is pointed to namecheap. domain.com is pointed elsewhere.
I need to update @.sub.domain.com for it to accept it.

(I know this setup works as I came from a WRT54GL with Tomato firmware that had no issue updating)

jimp

OK. It's possible that their dyndns API has a problem with that particular setup then. I don't have anything even close to that setup to test.

I'd need to see the exact update URL used by tomato to know what might fix it.

	// +opt +opt +opt
	sprintf(query, "/update?host=%s&domain=%s&password=%s",
		get_option_required("host"), get_option("user") ? : get_option_required("domain"), get_option_required("pass"));

	// +opt
	append_addr_option(query, "&ip=%s");

I took this from Tomato's source.
I'm not well versed in coding, but I'm pretty sure that's where it updates to.
so in my case, it would look like:

update?host=@&domain=sub.domain.com&password=somethingcomplicated

jimp

I think I see where the problem might be, in our code, it assumes for .com (and most others) that the domain part is only domain.tld, so it's probably splitting that into @.sub for the host and domain.com for the domain.

Not sure if there will be any easy way around that, I'll have to dig at it a little.
