Ok,

Any thought son the mod_python error?
    
        
Cobbler's mod_python component is trying to connect to cobblerd using 
the server value contained in /etc/cobbler/settings.    It's unable to 
do so given the way you have Apache set up.

In a stock Apache configuration, this problem will not exist.

Cobbler's mod_python aspects are required for operation.  It may be as 
simple as changing the server address.



  
      
The "server:" setting in cobbler is the IP of the VLAN interface which 
resolves to eden.manage.potsdam.edu. The same IP has been assigned to 
listen in httpd.conf

>From what I can gather, apache is listening on the ip (port 80, 443) 
of eden.manage.potsdam.edu as well as cobbler.
    

 From scripts/services.py (the mod_python handler from the source checkout)

    # instantiate a CobblerWeb object
    cw = CobblerSvc(
         apache   = apache,
         server   = "http://127.0.0.1:%s/cobbler_api" % http_port
    )


It seems to be unable to connect to 127.0.0.1.

Cobbler's Apache config file (cobbler.conf in /etc/httpd/conf.d) proxies 
these as follows:


ProxyPass /cobbler_api http://localhost:25151/
ProxyPassReverse /cobbler_api http://localhost:25151/

ProxyPass /cobbler_api_rw http://localhost:25152/
ProxyPassReverse /cobbler_api_rw http://localhost:25152/

It may be that "localhost" is the problem and you may want to change it.

There is also a selinux boolean about allowing apache to connect out but 
"cobbler check" will report if that is ever a problem.

I did the same digging ;) looking at cobbler source and settings. Added a "Listen 127.0.0.1:80" to httpd.conf to resolve the issue. This satisfies our requirement to stop apache from glomming onto all bound IP addresses and only respond to cobbler (and other web requests) from a specific VLAN.

Thanks again!

Also,
has anyone ran into the following error when setting up the cobbler 
server to be on 3 VLAN's and restricting apache to Listen to a 
specific IP?
