DNS isn't responding to nslookup

[alwaysweb]

If I SSH in to any other server and then do:

$ nslookup (to enter interactive mode)

Then

server ns19.alwayswebhosting.com

Then

djcracky.com

(a site hosted on server10)

It comes back with SERVFAIL... Whats wrong?

I checked

/etc/rc.d/init.d/named status and it appears to be running fine with a few PID's.

Thanks for any advice!

grep the /var/log/messages file for the domain name so see why bind had a problem loading the zone.

It wont respond for any domain on the server....

tail of /var/log/messages relating to restart of named:

I only see a few FTP sessions in 'messages' about djcracky.com. Another domain that isn't loading whose DNS has had sufficient time to propagate is: worktime.org


Here's the grep of message for both domains:


May 20 20:22:43 plain PAM_pwdb[23567]: (ftp) session opened for user worktime by (uid=0)
May 20 20:29:45 plain PAM_pwdb[23567]: (ftp) session closed for user worktime

Propagation confirmed by visiting:

and
http://betterwhois.com/bwhois.cgi?domain=worktime.org

Thanks for any help!

P.S.

/etc/named.conf does contain....


zone &djcracky.com& {
type master;
file &/var/named/djcracky.com.db&;
};



and


zone &worktime.org& {
type master;
file &/var/named/worktime.org.db&;
};



and the contents of each of those files respectively are:

The name servers ns19.alwayswebhosting.com and ns20.alwayswebhosting.com have been registered with our registrar and are pinging fine by the server and for me as well:

ns19 - 64.246.43.200
ns20 - 64.246.43.201


We are trying to transition away from ensim (we have 10 servers, 8 with ensim) so i do have experience troubleshooting ensim's quirks... especially related to DNS. This is our 2nd cpanel server, and haven't see this before. Thanks!

I can provide access to the box as necessary. Please consider this 'thread' urgent.

P.S.S.

When adding a site, at the bottom of WWWAct 2.5 output, I get:

&snip&....
DocumentRoot: &/home/rochebug/public_html&
Setting Password
Restarting NameServer
Restarting apache
Ftp Password Files synced
ndc: connect: connection refused


Even though named restarts fine via the GUI and command -line. Help!

 

[alwaysweb]

still investigating further...


By comparing /etc/named.conf from our other functional cpanel server (only difference is this server is set up with its own ns1/ns2.domain.com)

Noticed

include &/etc/rndc.key&;

wasn't included right before the zone definitions. Included that and was able to get:

[email protected] [~]# rndc reload
rndc: reload command successful

and now a named restart says:

....
May 22 07:55:56 plain named[19781]: command channel listening on 127.0.0.1#953

so at least the control panel is there now! I can nslookup then 'server ns19.alwayswebhosting.com' and it responds properly when you query 'aol.com' or 'yahoo.com' but still SERVFAIL 's for any domains set up on its own DNS server.

Help!

Just in case no one ever found a resolution for this I figured I'd help out since i just had the same problem.

If you have the domain on one server, ex. SERVER A. And you have nameservers for the same domain from SERVER A on SERVER B, SERVER A will get dns errors when trying to communicate with SERVER B, whether it be via email etc. However a quick fix is to add on the domain DNS entries on SERVER A the A entries for the nameservers and their respectable ips located on server B. Hope this helps out feel free to email me if you need clarification!
