Namecheap dynamic dns Not Updating

Trel

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

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.

That implementation looks like it could cause problems with many country tlds such as ".co.uk" or similar as "@.sub.domain.com" has the same separations as "@.domain.co.uk"

No, there is code specifically to handle domain.co.uk, there is a list in the client that knows how many levels deep TLDs go and sets exceptions based on the TLDs offered by Namecheap.

Might have to hack it so if you put in @ for the username and the actual sub.domain.com for the hostname then it would do the right thing… might be a bit before I'd have a chance to take a crack at it, I haven't touched the dyndns code in a while, it's not terribly complex though.

Since the "@" and the no username part only exists for namecheap, I can't imagine it being too difficult to do that with an if statement in general.
Other than the program the other person linked earlier, is there any interim solution I can do in the mean time?

Is curl or wget installed by default? If so I imagine I could temporarily install the cron package and do it that way.

"fetch" is there, curl may or may not be there depending on the packages you have installed.

fetch is capable of grabbing/hitting a page, e.g.:

fetch -o /dev/null http://blah.blah/blah

That would make a page request and ignore the result.

This look good (as I'm not quite familiar with fetch)

/usr/bin/nice -n20 fetch -o /dev/null https://dynamicdns.park-your-domain.com/update?host=@&domain=sub.domain.com&password=<password></password>

Be sure to enclose the URL in quotes, but otherwise, yeah I think it looks OK.

I have same issue. At one point I was able to update domain.net with @.domain.net under hostname but not subdomain.domain.net
Now nothing's updating. IP ADDRESS never updates and stays at 127.0.0.1 . I deleted multiple times everything. Chatted with support but their response is to use different client or manually update ip, how will I know if it will work once IP changes??

My goal was to have unused domain for dynamic DNS.

My register is still godaddy.
If someone has it working with other service please share. I would be willing to transfer my domain there for about 10-15 per year.

I have been using Namecheap ddns for years, had a problem once when their servers went down, but since then all is well.

I use a single subdomain.domainname.com with the subdomain record type set to A (address)

I haven't tried it with the @ hostname setting yet.

I also use the free dyndns service as a backup. I wished the pfsense service would force a connection to their server every few weeks.

Was this ever fixed for Namecheap, or do I still need to use the cron job and fetch?
