How to troubleshoot problems...

[aceinc]

I have installed and can run Zimbra client and administration on CentOS 5.2 x86_64.

I have one comment and one problem

The comment, if I goto http://mydomain.com:7071, I get a few square boxes followed by the letter 'P', however if I got https://mydomain:7071 everything works well. This seems odd.

My problem, and I am interested in how to troublshoot as well as the resolution is a big red X next to MTA in the Admin interface server status.

Where can I find log files and other stuff that will tell me what is really going on so I can see what silliness I have done?

You'll find the log files here: Log Files - Zimbra :: Wiki You should also run the following commands to check your DNS & hosts file setup is correct:

cat /etc/hosts
cat /etc/resolv.conf
dig yourdonaim.com mx
dig yourdomain.com any

and post the output (plus log file infor) when you've done your investigating. There are also likely to be threads in the forums that cover your problem, do a search for those. It also helps to know if you're on NE or OSS version of Zimbra and which operating system you're using. Run this command: 'zmcontrol -v' and add the output to your forums profile.

You requested the "log infor" unfortunately I do not know where that lives.

The version stuff;

Release 5.0.8_GA_2462.RHEL5_64_20080709164104 CentOS5_64 FOSS edition

My host file;

# Do not remove the following line, or various programs
# that require network functionality will fail.
# 127.0.0.1 mail.aceworld.com mail localhost.localdomain localhost
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

My resolv.conf;

search aceworld.com
nameserver 66.184.210.75

dig mx;

It lives in the link I've given you above.

This is incorrect, please read the Quick Start Installation Guide for details of how to fix it..

If you're behind a NAT router (i.e. on a private LAN subnet) this is also incorrect, you'll need a Split DNS set-up.

You didn't run the commands I asked, this output is useless. Please search the forums for details on how to set-up Zimbra on CentOS5 and how to resolve the problems you have.

You also appear to have no external DNS records for the domain you have in your resolv.conf file. Is that your real domain name?

[aceinc]

Sorry I missed the link regarding the log files.

I did run each command as you had asked.

cat /etc/hosts
cat /etc/resolv.conf
dig aceworld.com mx
dig aceworld.com any

The name of the computer is mail.aceworld.com.

This computer is not behind a NATted firewall, it is BA naked on the internet.

I will be using this computer to host e-mail for a number of domains the first of which is aceworld.com.

I will look at the log files and see what I can find, as well as the quickstart guide.

There appears to be two problems with your DNS a) if I do a check via a terminal you appear to have no MX record and b) this report shows no domain records at all. You can also check your DNS records here: DNSGoodies.com - DNS tools, WHOIS, Open Relay Test, Reverse DNS, Spam Database Check, traceroute, ping and other utilities.

Bill:

I found my MX record problem, I recently switched DNS from Tru64 unix to Windows, and obviously don't know what I am doing.

The "Pingability" report seemed to say I have a problem, but not what the problem was. I ran the Pingability test on another domain that I have that uses another local mail server (that works fine) and I get the same error as aceworld.

I'm having a bit of trouble reconciling your DNS records that I see from here. Go to the DNS goodies site I gave you earlier and do a DNS query on your domain aceworld.com (it's near the top of the page). Then go to the Traceroute and Ping near the bottom and enter your server FQDN - mail.aceworld.com - they both return the same IP but a different IP from the DNS MX lookup. Those results confirm what I see when I do nslookup & dig for your domain. So, my conclusion is that you either have the wrong IP in your external DNS records or your local DNS has the wrong IP.

I'm also slightly confused (nothing new in that) by the fact that pingability can't find anything about your domain.

[aceinc]

Bill:

The DNS server is a different server than the computer that Zimbra is installed on. That is why there are two IP addresses. The default IP where my web and other stuff is happens to be the DNS server, a windows computer, and Zimbra is on a separate linux box.

The point I was making is that the MX record for your Zimbra server is different than the response (IP address) if you do a traceroute or ping - something is incorrect there. Do the test on the DNS Goodies site rather than using your local DNS server.
