|
This morning I noticed one of my ISP's nameservers was going a little bats**t and wasn't resolving names in the neooffice.org domain. This sounds similar to Samwise's problems with anoncvs being unable to resolve its IP.
I changed the nameserver config to better match the registration information on the root servers...the NS config on root domains point to one of my other domains while the nameserver was advertising a different set of name servers. I synced the two so, hopefully, this might resolve the issue (no pun intended).
Let me know if you have any "host not found" problems with either trinity, cvs, anoncvs, www, etc. in the next few days as a result of the new config.

I will check anoncvs as soon as I regain access to my Mac (could be in a few days). |

Well, I tried to get the source from the CVS a few minutes ago, and using anoncvs.neooffice.org didn't work, so I had to use the IP instead (again).
nslookup gives me an error message as usual, but host, which used to find the IP, does not seem to find it anymore. Both nslookup and host can find the IP for trinity.neooffice.org though. |

Works fine for me so I don't think this is a problem on Ed's end. Instead, I suspect that you have a flaky DNS setup or the DNS server that you are using is flaky. DNS, like most of the internet, assumes that all DNS servers throughout the world keep their data in sync. However, in practice I have found that this isn't always the case.

Also do you have a backup DNS server? I found from my ISP that the primary DNS had issues trying to resolve comptuers within my domain (e.g. main domain lookup was fine, but some of the other computers using aliases were goofy) but the secondary DNS had no problems at all finding the servers. So what would happen is the primary DNS would time out and then the secondary DNS would kick in.
One thing that may work is to find a DNS server that seems to be a bit more reliable on that lookup and set it as a backup server.

Also, if anyone is more expert in BIND configuration files than I I wouln't mind having someone take a look over them The problem that I had fixed was to change the nameserver records in BIND to match the nameserver records as they are on the root domains. The thought was that somehow the difference in NS entries was causing DNS servers to fail to resolve the primary DNS IP address for the domain.

Is this question for me ?
Well, I use whichever DNS my ISP assigns me. Whether there is a backup server, I do not know.
Edit : Right now both nslookup and host find the IP for anoncvs. Looks like the issue is on my end then. |

Strange. So is nslookup able to find the IP but the CVSROOT still doesn't resolve? That'd be something I've never seen before

I don't think so. I just didn't bother to try accessing the CVS again, but I'm (almost) sure it would have worked w/out the IP ...
I think Patrick is right, there must be an issue with the DNS setup on my end. |
