Replacing old email server with Zimbra

[wildgoosed]

We currently have qmail running on an old FC5 box that I'm in the process of replacing with Zimbra on Ubuntu 8.04.

I'm following this guide... http://howtoforge.com/installing_zim...uite_on_ubuntu

We have 1 Public IP address that we run all of our Internet services off of (behind an IPCOP box)

I've placed this new zimbra server (192.168.1.8) on the nextwork beside our old qmail server (192.168.1.4) and plan to just setup zimbra and change the port forwarding when done so that this whole process is fairly quick and transparent...

My problem is that when I'm about done the installation, I get this following error...

Fri Sep 26 08:19:49 2008 zimbra-ldap is enabled
Fri Sep 26 08:19:49 2008 Initializing ldap...
Fri Sep 26 08:19:49 2008 *** Running as zimbra user: /opt/zimbra/libexec/zmldapinit
IO::Socket::INET: connect: timeout at /opt/zimbra/libexec/zmldapinit line 160.


Can anyone help out?

I think this is a DNS issue. When I run /opt/zimbra/libexec/zmsetup.pl I get the following error...


Operations logged to /tmp/zmsetup.09262008-142825.log
Setting defaults...No results returned for A lookup of localhost
Checked nameservers:
209.202.110.120


DNS ERROR resolving localhost
It is suggested that the hostname be resolveable via DNS
Change hostname [Yes]

What should I have in /etc/hosts?

Like I mentioned above, This server is inside a DMZ behind an IPCOP box (orange network) and is using my ISP's dns servers.

What's in /etc/hosts?
What's the output of

hostname -f

?

/etc/hosts

127.0.0.1       localhost localdomain localhost
192.168.1.8     localhost.localdomain localhost
# 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

hostname -f

localhost

Please use a real hostname instead of localhost.localdomain in the 192.168.1.8 line in /etc/hosts and also in /etc/sysconfig/network (I think that's the correct file). Restart the system afterwards.

This box is behind a IPCOP box in a DMZ and is using my ISP's nameserver.

On the trusted network I'm using IPCOP as my DNS server.

For this mail server in the DMZ what should its hostname be?
