DNS Problem on Ubuntu

[filloweb]

Hi all.

I need to install Zimbra on a DMZ server ( 192.168.1.180 ) with Ubuntu 6.06.2 LTS and FQDN hostname ( /etc/hostname ) "mx.domain.it"
My default gateway ( 192.168.1.254 ) route correctly all port needed.

I haven't a DNS server in my DMZ or LAN but I use a ISP DNS ( 212.97.32.2 )

How can i configure my installation for a full Zimbra install on a server ?

Is right this howto to set-up bind9 on the same server?

In:

"/etc/bind/zones/domain.it.db"

from the example

// replace example.com with your domain name. do not forget the . after the domain name!
// Also, replace ns1 with the name of your DNS server
example.com.      IN      SOA     ns1.example.com. admin.example.com. (
// Do not modify the following lines!
                                                        2006081401
                                                        28800
                                                        3600
                                                        604800
                                                        38400
 )

// Replace the following line as necessary:
// ns1 = DNS Server name
// mta = mail server name
// example.com = domain name
example.com.      IN      NS              ns1.example.com.
example.com.      IN      MX     10       mta.example.com.

// Replace the IP address with the right IP addresses.
www              IN      A       192.168.0.2
mta              IN      A       192.168.0.3
ns1              IN      A       192.168.0.1

I change:
"example.com" with "domain.it"
"ns1.example.com" with "mx.domain.it"
"mta.example.com" with "mx.domain.it"
"mta" with "mx" and ip address 192.168.1.180
"ns1" with "mx" and ip address 192.168.1.180

In

"/etc/bind/zones/rev.1.168.192.in-addr.arpa"

from the example

//replace example.com with yoour domain name, ns1 with your DNS server name.
// The number before IN PTR example.com is the machine address of the DNS server. in my case, it's 1, as my IP address is 192.168.0.1.
@ IN SOA ns1.example.com. admin.example.com. (
                        2006081401;
                        28800; 
                        604800;
                        604800;
                        86400 
)

                     IN    NS     ns1.example.com.
1                    IN    PTR    example.com

I change:

"ns1.example.com" with "mx.domain.it"
"example.com" with "domain.it"

When I install Zimbra there's some errors on the DNS resolution.

Could you help me ???

This appears to be your third post on this subject, I've already answerd this questions once so please don't post duplicates.

You need a Split DNS set-up for mail delivery, follow the instructions on the wiki if you are a Ubuntu user or the other link in the wiki if you're on another o/s.

Ops...
I can't see the other post... The other posts return me an error of SPAM.

Sorry.

What are the error messages you are receiving ?

Would you also please perform these commands on the server where Zimbra is being installed and post the results :-

cat /etc/resolv.conf
cat /etc/hosts
dig @localhost domain.it ns
dig @localhost domain.it mx

Many thanks.

Hi,

thanks a lot for you support.

I've follow the guide Ubuntu 6.06 Server (Dapper Drake) Beginner's Install Guide - Zimbra :: Wiki
and the DNS chapter and I think all work fine.

Here "cat /etc/resolv.conf" output

nameserver 192.168.1.180

Here "cat /etc/hosts"

127.0.0.1       localhost.localdomain   localhost
192.168.1.180   mx.domain.it           mx

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Here "dig @localhost domain.it ns"
