cloudflare rdns problem!!!!

« on: May 12, 2012, 10:17:55 pm »

help i have pas all the test and i have forgot to make a rdns... the next day i was configure dns but i see for the first time this error "Failed to get AAAA from MX or your DOMAIN"
if i do a nslookup i only see the cloudflare default records and i cannot see the ip of my machine(server)...
i thought that it will be a problem but the process did not stuck anywhere.. except now...
it is a known error with cloudflare or is something else...
my domain is mafiasx.com and in this domain is the mail tha i give in the test ....here i have my main site so i cant mess with it..
but i have anather domain (so if i have to move to the he dns system i can only do with outher domain... but i don know how to change the given email..)
any sugestions... thanx..

my domain is mafiasx.com

The domain has two MX records. Only one of them have a AAAA record. However that should not be a problem. If the test did in fact require you to have a AAAA record for every MX, I'd call that a flaw in the test. The problem may have to do with the 24 hour TTL you have chosen for your records. If you tried the test before your records were complete and got something differently cached, then you'll need to wait 24 hours for the cache to expire before you can proceed with the test.

The host which the AAAA record points to is not reachable. There is a routing loop.

traceroute to 2001:5c0:1400:b::d505 (2001:5c0:1400:b::d505), 30 hops max, 80 byte packets

You'll need to fix that as well. Though the error message you got indicates that it never got far enough to notice this. I know the routing loop doesn't appear to be close to the mail server, but I tried to reach that mail server from four different locations and in all four cases I hit the same routing loop. I tested from two different HE tunnel servers, as well as 6to4 from two different ISPs.

And what's up with the subject? There was nothing about RDNS in your post. There is an RDNS problem as well, but you are not using cloudflare for RDNS, you are using gogo6.com. ns1.gogo6.com. returns valid RDNS for your mx, ns2.gogo6.com. returns NXDOMAIN. That sounds like gogo6 has a problem with synchronizing their secondary DNS server. I don't know if the routing loop can be blamed on gogo6 as well. It certainly doesn't give me a good first impression of gogo6. If those problems persists, you should look for another tunnel provider.

I see that forward DNS for your mx is now pointing to an HE tunnel. But the old records with 24h TTL are still cached in some locations, so I will wait until tomorrow before I look much more at it.

The IP was responding on port 25 the first time I tried. But then it started getting flaky, and now I can no longer traceroute to your network.

You don't seem to have RDNS for the new IP yet. The NS records for the IP range point at the HE DNS servers, which reply with NXDOMAIN. I think that is what happens until you start configuring something.

You now have two options. Either you use the HE DNS servers and configure the RDNS records you want through the webinterface. I don't know how that works, since I never used that myself. But I should probably look into it. Or you specify your own DNS servers on the tunnel configuration page, which is what I did because I hadn't realized the other option existed.

Yes, you may have to wait longer, because you moved to a different DNS provider. The records indicating which DNS provider is responsible for your domain have a 48 hour TTL.

Before you started making changes, your forward DNS was the only thing that worked without problems. There wasn't actually any need to move your forward DNS to HE. You could have used cloudflare for forward DNS and HE for RDNS, and everything would have been just fine. But now that you have moved it, you may as well keep it all in one place.

If you don't want to wait for the 48 hour TTL to expire, you can create records at cloudflare identical to those at HE, then those will be used until the NS records expire.

If I had known which DNS server you were using, I could verify if this 48 hour TTL is really the problem you are facing, but you only listed it as unknown.
