Hi,
I've got a new default install of CentOS 5.2 on which I am trying to get
Cobbler installed. I can get the service running, but clicking any link
(other than DOCS) on the menu results in a python error message. It
appears that cobbler_api and cobbler_api_rw are being blocked, but I
can't figure out how. SELinux is off, firewall is off. Attempts to
navigate to http://<server>/cobbler_api
<http://%3cserver%3e/cobbler_api> results in Service Temporarily
Unavailable. I've searched Google, but have not found anything that
has helped.
Any troubleshooting help would be greatly appreciated.
Clicking any menu option results in Cobbler web ui displaying:

Can you check /etc/cobbler/settings to see if the following two are set?
xmlrpc_rw_enabled: 1
xmlrpc_rw_port: 25152
Also, check if your configuration is valid, by typing "cobbler check".
If all looks ok, make sure the cobblerd service is running.
Kind regards,

Yes, it all looks good as far as I can tell.

(Replying to my own reply in order to share the solution)
I've found that the cause was my /etc/hosts.
I had:
::1 localhost.localdomain localhost <SERVERNAME>
When I changed it to
127.0.0.1 localhost.localdomain localhost <SERVERNAME>
Cobbler web ui starts working just fine.
It also works with
127.0.0.1 localhost.localdomain localhost <SERVERNAME>
::1 ip6-localhost.localdomain ip6-localhost pi6-<SERVERNAME>
Hope this helps someone.

If you hadn't said "new install", my suspicion would have been that
you've upgraded to this version of Cobbler from a version before 1.0,
before the mod_python infrastructure was introduced, and therefore have
a "cobbler.conf.rpmnew" file hanging around in your Apache
/etc/httpd/conf.d directory. If that was the case, I would have said
copy this file over the non ".rpmnew" one and restart httpd.
I assume you are installing with the latest RPM from EPEL 5 testing? The
latest is 1.2.4. Maybe you installed with --noscripts or something else
weird?
