SERVFAIL

Hi,

I have a VPS which runs about 4 sites one of which was actually hosting name serves for other domains (eg: ns1.example.com, ns2.example.com).

Everything was functioning smoothly until 2 days back when VPS was down for couple of hours. Server company informed me it was a kernel bug. Once they informed everything up and running I found that I could not access any of my domains my typing the URL. I use webmin as control panel and I could access webmin as well as root using IP.

When I try host www.example.com it says SERVFAIL

intodns result for hosting domain includes

SOA record No valid SOA record came back! WWW A Record ERROR: I could not get any A records for www.example.info! Missing nameservers reported by your nameservers You should already know that your NS records at your nameservers are missing, so here it is again:

ns1.example.info. ns2.example.info.

BIND DNS file for hosting domain is as follows

$ttl 600

@ IN SOA host.example.info. example.example.net. ( 1315932274 10800 3600 604800 600 )

            NS      ns1.example.info. 
            NS      ns2.example.info.
            NS      example.info.
            NS      host.example.info.

example.info. IN A xxx.xxx.xxx.xxx www.example.info. IN A xxx.xxx.xxx.xxx ftp.example.info. IN A xxx.xxx.xxx.xxx m.example.info. IN A xxx.xxx.xxx.xxx ns1.example.info. IN A xxx.xxx.xxx.xxx ns2.example.info. IN A xxx.xxx.xxx.xxx host.example.info. IN A xxx.xxx.xxx.xxx localhost.example.info. IN A 127.0.0.1 webmail.example.info. IN A xxx.xxx.xxx.xxx admin.example.info. IN A xxx.xxx.xxx.xxx mail.example.info. IN A xxx.xxx.xxx.xxx example.info. IN MX 5 mail.example.info. example.info. IN TXT "v=spf1 a mx a:example.info ip4:xxx.xxx.xxx.xxx ?all"

Any help is highly appreciated.

Thanx

Howdy,

Well, the DNS zone file you have there looks good... intodns.com is complaining about missing SOA, NS, and A records -- but those are all present in your zone file.

So, it doesn't appear that zone file is what intodns.com is seeing.

You may want to start by simply restarting BIND -- maybe something happened that doesn't have your zone file loaded.

You may also want to check the nameservers for your domain, and verify that those do indeed point to your server.

Hi,

I restarted BIND server couple of times. i reinstalled BIND. I have tried rebooting the server too. I haven't changed anything at my domain registrar. In fact I have 4 domains running under 2 domain registrars. All of them having issues. I anyway rechecked domain cpanel settings and everything looks as usual. Any more suggestions pls

Do you see all that DNS information when you look at Server Configuration -> DNS Records? Or are the NS and A records missing when you look there?

Hmm... I'm actually referring to within Virtualmin -- for the Virtual Server that you're having problems with, you should see your DNS records in Server Configuration -> DNS records.
