Local DNS issues SERVFAIL for one domain all others work.

[Vernon Brown_4]

I'm running named on a Fedora Core 5 HP Pivilion for speedy DNS on my LAN. The LAN is connected to the Internet through a Linksys router. It is working great for all but one of my local domains. I've been working with that one for several days now and I'm pretty sure the named.conf and the zone file entries are correct. I suspect the problem might be in the DNS cache.

Any suggestions on how I can find out if the problem is coming from the DNS cache?


[code]
Zone file in /etc/named

$TTL 86400
stkusers.com. IN SOA stkusers.com. veb.cabot-biz.com. (
20031208 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)
IN NS cabot-biz.com.
stkusers.com. IN MX 10 cabot-biz.com.
stkusers.com. IN A 66.112.33.128
*.stkusers.com. IN CNAME stkusers.com.



And in the file /etc/named.conf:

zone "stkusers.com" IN {
type master;
file "stkusers.zone";
allow-update { none; };
};
[/code]

Use "rndc dumpdb" to see dns cache. For specific options (zone dump) see man page. Default dump all zones in /var/cache/bind.

Thanks for your response !!

Interesting; the command returns nothing and there is no /var/cache/bind
/var/cache is there but no bind there.
The box is running Fedora Core 5.

From change log for caching-nameserver-7.3-5.FC5 RPM :

- change default locations of dumpdb & stats file to /var/named/data

Ok found the dumped data. Thanks !!

I'll scrub it for clues.

Ivan Thanks; found the problem; the zone file was owned by root and grouped with root. Changed group to named and restarted named.
