<B>Subject: </B>[AG-TECH] Bridge Registry Timeout<BR>
<BR>
Hello all,<BR>
<BR>
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). <BR>
<BR>
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.<BR>
<BR>
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:<BR>
<BR>
./Bridge -n "RIT Brooklyn" -l RIT<BR>
<BR>
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:<BR>
<BR>
reached inactivity timeout and have no clients; exiting<BR>
Traceback (most recent call last):<BR>
File "/usr/lib/python2.6/site-packages/AccessGrid3/AccessGrid/AGXMLRPCServer.py", line 63, in run <BR>
self.handle_request()<BR>
File "/usr/lib/python2.6/SocketServer.py", line 262, in handle_request<BR>
fd_sets = select.selectP[self], [], [], timeout)<BR>
error: (4, 'Interrupted system call')<BR>
<BR>
<BR>
However when there are clients connected it every so often just prints out the connection information as follows:<BR>
<BR>
max_unicast_mem is 32<BR>
myhostname=brooklyn<BR>
myhostipaddress=129.21.x.x<BR>
<BR>
using multicast <BR>
ucport [data]=51390 ucport [rtcp]=51391<BR>
mcport [data]=56384 mcport [rtcp]=56385<BR>
making multicast port [0]<BR>
making multicast port [1]<BR>
No bridge.acl file found, no ACL set<BR>
<BR>
If anyone has information that could help me track down where this problem is, it would be a great help.<BR>
<BR>
Thank you in advance,<BR>
