[cobbler] Replication fails with "connection refused"

Ok, well that wasn't the issue... I've finally pulled my head out and figured this out.  The offending issue is that on line 357 of /usr/lib/python2.6/site-packages/cobbler/action_replicate.py we see this:

self.local = xmlrpclib.Server("http://127.0.0.1/cobbler_api")

Which implies that we're configured to listen on localhost:80 ... which I was not.  I had apache configured to listen ONLY on my external IP.

I'm thinking that this should be changed... perhaps moved into a configuration directive and not hard-coded to localhost.

Thoughts?

Hi there! It seems the server (or a device in the network path) is sending an tcp rst (reset) to the client. Can you please verify this by using a tool like telnet/netcat?

Hi Folks,

I'm having some trouble getting replication going under the latest 2.5 dev release.  I suspect there's something up with my configuration, but I can't seem to find what it is.  I cloned my master cobbler server to a remote site, change the relevant hostname pieces and the new slave server seems to work in itself locally.  But when I attempt to replicate from the master, I get the following.

Can anyone clue me in as to what might be happening?
