Hello all,

My apologies if this has been covered by other people in the past, however I 
have spent considerable time searching the archives for instructions on how to 
fix this issue (or even exactly where it stems from).

Here at RIT I have been working on setting up a Unicast Bridge, however I have 
run into a snag. I have the bridge up and working fine, I consistently have 2 
of our own nodes connected through the bridge at all times that they are up, so 
it works as a bridge already. Our problem is that for about 5 minutes the 
bridge shows up in the registry list as an option for the nodes, but after that 
5 minutes it disappears from the registry list if a registry purge is used, or 
if a node logs into AG after the registry timeout happens it is gone. If the 
bridge is in the list from those 5 minutes, and the list is not purged, that 
node can still connect and disconnect from the bridge server without a problem, 
so it is still up and working.

For details, I am running on Fedora 12, using the Bridge python script that is 
installed with AG3.2 (it has a created date of 2005/12/06 in case it has been 
updated). When running the script I am running it with the following command:


./Bridge -n "RIT Brooklyn" -l RIT


I have been watching the log file that I have been directing all the output to, 
and the beginning I have found an interesting entry, but this is only when 
there are no clients connected:


reached inactivity timeout and have no clients; exiting
Traceback (most recent call last):
  File 
"/usr/lib/python2.6/site-packages/AccessGrid3/AccessGrid/AGXMLRPCServer.py", 
line 63, in run
      self.handle_request()
  File "/usr/lib/python2.6/SocketServer.py", line 262, in handle_request
      fd_sets = select.selectP[self], [], [], timeout)
error: (4, 'Interrupted system call')



However when there are clients connected it every so often just prints out the 
connection information as follows:


max_unicast_mem is 32
myhostname=brooklyn
myhostipaddress=129.21.x.x

using multicast
ucport [data]=51390   ucport [rtcp]=51391
mcport [data]=56384  mcport [rtcp]=56385
making multicast port [0]
making multicast port [1]
No bridge.acl file found, no ACL set


If anyone has information that could help me track down where this problem is, 
it would be a great help.

Thank you in advance,
