Split DNS and etc/hosts problem, again.

See the examples in the Split DNS article for the correct format.

Soooo, lets start over again.

I have a Red Hat installed on a PC, and i want to use it as a Zimbra server. Are the "Split DNS" configuration all the things I have to do to make it work?

As you can see, I'm a total begginer on this matter. So I appreciatte all your patience.

Yes, the DNS A & MX records plus the hosts file are what needs to be correct.

The following are the things you need to fix:

Code:

zimbraloco.com.         2592000 IN      MX       mail.zimbraloco.com.  
mail.zimbraloco.com.  2592000 IN      A       192.168.1.7

zimbraloco.com.         2592000 IN      NS      ns1.zimbraloco.com.
ns1.zimbraloco.com.  2592000 IN      A       192.168.1.7

Code:

127.0.0.1 localhost.localdomain localhost
192.168.1.7 mail.zimbraloco.com mail

Make those changes and run the 'Verify ...' commands again.

First, I want to Thank you very very much for your infinite patience with rookies like me, he.

I pasted those fixes... but now i cant run "service named start"

Code:

Error in named configuration:
dns_rdata_fromtext: db.server.example.com:12: near 'mail.zimbraloco.com.': not a valid number
zone zimbraloco.com/IN: loading from master file db.server.example.com failed: not a valid number
zone zimbraloco.com/IN: not loaded due to errors.

this is db.server.example.com:

Sorry that was my fault, I can't imagine why I put those number sin there - must be my cop/paste skills have gone downhill.

The records should look like this:

Code:

zimbraloco.com.         IN      MX       mail.zimbraloco.com.  
mail.zimbraloco.com.    IN      A       192.168.1.7

zimbraloco.com.         IN      NS      ns1.zimbraloco.com.
ns1.zimbraloco.com.     IN      A       192.168.1.7

Let's say that I'm either incompetent or just having a bad day. One important piece of information is missing, the priority on the MX record, as follows:

Code:

zimbraloco.com.         IN      MX      20 mail.zimbraloco.com.

Zimbra wont start!

Why is this last error? It has to do with the port conflicts previusly encountered?

Your hosts file is still incorrect, you didn't follow the example I gave you earlier. The format should be as follows:

Code:

127.0.0.1 localhost.localdomain localhost
192.168.0.7 mail.zimbraloco.com mail

You didn't post the contents of your resolv.conf but I also assume that it reflects the correct IP of your DNS server?

[root@mail ~]# cat /etc/resolv.conf 
search zimbraloco.com
nameserver 127.0.0.1

This is my resolv.conf, just as the SplitDNS example.

That's fine but you still need to fix the hosts file.
