Take a look here:

Documentation can be found here:

Docs on Conga (Luci and Ricci) are here:

http://sources.redhat.com/cluster/conga/

I don't know if this is newer because i made a large way around even
trying to use conga after i spotted that it utilizes turbogears (which
has a huge dependency tree just to get anything out of it).

The FAQs on http://corosync.org/ and http://openais.org/ could help
here. Unfortunately the FAQ entry about firewalls has no content.

Bug?!

A "netstat -tulpen" on a root shell should show the ports that corosync
and openais listening on. They use a single multicast port if i'm not
mistaken.
