problem about host lookup.failed

the problem when starting zimbra service
in Fedora 4

Host lookup.failed
------------------------------------
I have changed the host name to mailhost.example.com and added FQDN
before hostname, as described in the quick-start, but it doesn't work.
Have any suggestion?

Welcome to the forums.

Does the host actually point to your internal IP address of the Zimbra server? Do you also have a local DNS server with MX records pointing to the Zimbra server? Were there any problems in the install logs?

I'm not sure about these issues. I didn't install the spell package, for this package was failed to be installed, and there is not other problem when installing.

What has the spell package got to do with a hostname problem? You need to look in the install logs and see if there were any problems. If you are still having problems with hostname resolution you either have a hosts file problem or your DNS set-up is incorrect (or DNS isn't installed).

Thanks for your reply. there is parts of the logs:

Maybe the reason is that I changed the hostname and edited /etc/hosts after the installation. Reinstallation may solve the problem, but is there any other ways? I make use of the zmprov command, however, there is error:

Hi,
You defenetly have a DNS issue. (I like to state the obvious).

So, zimbra can't find it self. can you post your hosts file? I think you said this was on FC4, so do you have IPv6 disabled?

Also, do you host your own DNS? If not, do you have a DNS server on your network that Zimbra can see? I say this because you might be able to work out some split DNS stuff.

Did you install SE Linux, and is it turned on?

Thanks,
john

Re-installation never solves a problem, it only works around it.

Make sure that the host has a valid DNS A and MX record:

To check the A record:

# nslookup mail.exampledomain.com

-you should get the ip address of the zimbra server


To check the MX record:

# nslookup
>set type=MX
>exampledomain.com.

-you should get the ip address of the zimbra server (note the trailing period ".")

I noticed in your post that the server name was set to fedora.xjtuse.edu.cn, however, that doesn't resolve on my end (says invalid domain). Is xjtuse.edu.cn a valid internet domain? My guess is it only existed in your /etc/hosts file.
