Hello,
I apologize if this has been addressed else where. I searched the
archive and didn't find the answer. My group is in the process of
upgrading to 3.1 from 2.4. For various political reasons I've been
asked to keep a 2.4 server running for the near future. I've had a
2.3/2.4 Venue/Bridge server operational under RHEL3 for over 3 years now
and am quite comfortable with setting up and maintaining 2.X AG.
We've acquired new hardware for the 3.1 Venue/Bridge setup running
RHEL5 and I wanted to run both the 2.X and 3.X servers on the same box
to make my administrative life easier. Using the docs from:
http://www.vislab.uq.edu.au/research/accessgrid/software/rhel/
I installed all the AG3.1 RPM's (and pre-requirements) as well as the
2.4 compatibility set. I have the new 2.4 Venue Server up and
operational and working fine from 2.X clients, but I can not get the
bridge server to connect to the new Venue Server correctly.
Logs on the new bridge server when it connects to the new venue server show:

The configuration file for the Bridge Server is:
[BridgeServer]
name = RENCI3
location = EUROPA
qbexec = /usr/bin/QuickBridge
portMin = 30000
portMax = 30999
[https://venues3.renci.org:9000/VenueServer]
type = VenueServer
Everything looks correct, the bridge connects to the server, gets all
the Venues, but QuickBridge never starts up. If I point this same
bridge server at my old 2.4 server (under RHEL3), it establishes a
connection, and will serve Unicast just fine, so I don't think its the
bridge server. I already dropped the firewall on both the Venue and
Bridge server just to be sure it wasn't a port issue.
I have 2 things I think it could be:
1) conflict with certificate name. I am using the certificate from my
old server (venues.renci.org) on this test server (venues3.renci.org).
Thinking it might be a naming conflict, I renamed the new server
"venues.renci.org" and that didn't solve the problem, and I see no
complaints in the logs about certificate issues.
2) The newer wxPython (2.8.7.1) and associated pre-requirements for AG
3.1 (downloaded from EPEL) are too new to correctly work with the AG 2.4
setup. I ran into a couple of issues trying to start the 2.4 Client,
problems with wxPython compatability, but nothing on the server side,
and everything else on the 2.4 Venue Server is working fine as far as
Multicast (I can connect from a 2.4 clients and have sessions just
fine), its just the Unicast bridge won't connect and start the
QuickBridge for any of the Venues.
Before I spend the time to rebuild the software stack myself using
older code on RHEL5 (wxPython 2.5.x, etc), I thought I would ask if
anyone has experienced this before, and knows of a quick solution or can
offer a direction for me to look in.
Thanks,
-Brad Viviano
