Hi All

I am new to Linuix an am trying to get a machine up and running to show my boss its good and may be he will pay for some training.

I am getting a dns error when doing ns lookup

** server can't find mydomain.com: SERVFAIL (mydomain used instead of my own in the error)

I am following this document http://wiki.zimbra.com/index.php?tit..._Install_Guide

I am in a nat nework and have setup hosts with my internal nat address and setup the correct forwarders as per the document exactly. I can ping outside domains and can ping mail.mydomain.com and get a correct responce back.

Can anyone help me out here?

Thanks Glenn

Hi,

It looks like an error with the zone file. Take a look at /var/log/messages (or whatever file bind logs are written) to see if you find the error.
If you have followed the howto to the letter, post the output of:
and the zone file (/etc/bind/db.mydomain.com)

Regards

DNS is one of few things where substituting fake domain names for real ones makes it more difficult to diagnose problems. One reason is that we may need to compare the results you get with the results we get using exactlt the same domain. DNS problems often exist entirely outside of what you may be doing. Please do not substitute any domain names in any data or messages.

There are TWO different roles a DNS server can perform. I need to know which role(s) you are attempting to do. One role called "authoritative" is where your server(s) provide DNS information about your domain(s) to the rest of the world. The other role is called "caching" or "resolving" and provide a means for your access to the internet to get DNS information about other domains. Knowing which you are trying to do provides an important perspective. The BIND name server can do both, and is typically configured to do both.

Please post the configuration files exactly as you have set them up right now. The files of interest are "/etc/bind/named.conf" plus each file listed in that file on the lines that begin with "include". Without seeing the config files and the real domain names, the only help I can give at this point is to tell you that your error message means that a domain name is not configured in whatever server the query was directed to.

Thanks all for the advise. I managed to out a : instead of a ; in my db zone file

Many thanks

Glenn
