[ubuntu-cloud] Separate CLC.CC servers not seeing nodes.

Mon Mar 28 10:13:51 UTC 2011

Thanks for getting back to me Ahmed,

So, I'm pretty positive they are registered. On my CC in the
registration.log I get this:

2011-03-28 11:06:19+01:00 | 5525 -> Node 192.168.92.43 is already
registered.
2011-03-28 11:06:19+01:00 | 5528 -> Node 192.168.92.41 is already
registered.
2011-03-28 11:06:20+01:00 | 5519 -> euca_conf --register-nodes returned 0

But in the cc.log things don't look right.

Now I've checked and passwd-less login is working for the eucalyptus user.
Is there any other logs I should be checking for clues?
