Hi, I have a working cobbler installation at work, but I've created a completely now one at home. Unfortunately, it does not work. I installed it by adding the EPEL repo and "yum install cobbler cobbler_web". I removed the cobbler-user from /etc/cobbler/users.digest  and added an "admin" user. When I run "cobbler check", it just says that httpd does not seem to be running and proxying cobbler. httpd is running, but I only get a "503" error-code in the access-log from running cobbler check 192.168.1.19 - - [16/Nov/2011:01:38:09 +0100] "POST /cobbler_api HTTP/1.0" 503 401 "-" "xmlrpclib.py/1.0.1 (by www.pythonware.com)" Is there a way to make it say what is actually wrong beyond a 503? In the cobblers-log, I only get this: Wed Nov 16 01:42:29 2011 - DEBUG | API handle initialized Wed Nov 16 01:42:29 2011 - DEBUG | XMLRPC running on 25151 etc. Incidentally, I can't login to the web-interface with the password I set.
