[nsd-users] CNAME from another zone

Hi guys,

I've been using NSD for about a year now and I love it. But I've been
facing something strange for a while now and thought I should share.

I have a mailman server hosting around 40 mailing lists using different domain
names. The thing is, I'd like to use an A record for the primary host name
and use CNAME records for the other domains. Lets say my server was
lists.domain.tld, and I want to have another host name lists.domain2.tld. Having

lists.domain2.tld.      3600    IN CNAME       lists.domain.tld.

Will generate the following error:

CNAME and other data at the same name

I've googled for this error but to no avail. any ideas? BTW both domain.tld
and domain2.tld are hosted on my server.

Thanks,
Mohammad

You have other RR (including double CNAME) with same owner (ie. name
lists) in the zone file for domain2.tld

But being crypting and trying to hide real names doesn't really help
debugging your problem

[nsd-users] CNAME from another zone

Hi,

Thanks for you prompt response.

Well I wasn't being cryptic, I just wrote an example from my mind. DNS as
you know is a public database :). Anyways, here is a complete zone file.

$TTL    86400
@       IN      SOA     ns1.tagidomains.com.    mail.tagidomains.com. (
        2009031001      ;       Serial YYYYMMDDnn
        16384     ;       Refresh
        2048       ;       Retry
        1048576      ;       Expire
        2560)    ;       Minimum
autodiscover.tag-legal.com. 3600    IN A           89.28.217.25
www.tag-legal.com.        3600    IN A           89.28.217.117
demo.tag-legal.com.       3600    IN A           89.28.217.116
tag-legal.com.            3600    IN A           89.28.217.117
lists.tag-legal.com.      3600    IN CNAME       lists.tagorg.com.
lists.tag-legal.com.      3600    IN MX     10   mx1.tagorg.com.
lists.tag-legal.com.      3600    IN MX     10   mx2.tagorg.com.
lists.tag-legal.com.      3600    IN MX     20   mx3.tagorg.com.
tag-legal.com.            3600    IN MX     10   mx2.tagorg.com.
lists.tag-legal.com.      3600    IN MX     20   mx4.tagorg.com.
tag-legal.com.            3600    IN MX     10   mx1.tagorg.com.
tag-legal.com.            3600    IN MX     20   mx4.tagorg.com.
tag-legal.com.            3600    IN MX     20   mx3.tagorg.com.
tag-legal.com.            3600    IN NS          ns3.tagidomains.com.
tag-legal.com.            3600    IN NS          ns1.tagidomains.com.
tag-legal.com.            3600    IN NS          ns2.tagidomains.com.

Where lists.tagorg.com is the primary hostname of my mailman server.

The system consists of a patched version of VegaDNS running on MySQL with a perl
backend that generates all the zone files, then checks them with zonec and
compiles the NSD database.

Thanks again,
Mohammad

You have other RR (including double CNAME) with same owner (ie. name
lists) in the zone file for domain2.tld
