Hi. Our Campus is protected by a firewall and proxy that obligates users to authenticate throu the proxy in order to stabilish any conecction to internet. MOreover our network isn't Multicast capable (only unicast).
We had installed an AccessGrid Node using 2.4 AGToolKit with a local bridge server and everything worked just fine. Now we're moving to version 3.0.1 final and we've had many troubles to make it work because our unicast bridge doesn't registrate properly as the new squema in AG3 had change and no local bridge can be implemented. Our questions are: - How can we implement a local Unicast Bridge using AG3? - Can a unicast bridge register to a local service instead the default server (http://www.accessgrid.org/register/peers.txt)? if it is... how can we implement that service? Here is the output of the Bridge when we try to execute it: --------- [accessgrid@bridgeserver ~]$ Bridge -nFACYT-UC -lVenezuela Traceback (most recent call last): File "/usr/bin/Bridge", line 181, in ? main() File "/usr/bin/Bridge", line 176, in main bridgeServer = QuickBridgeServer(name=options.name, location=options.location, listenPort=options.listenPort, qbexec=options.qbexec, portRange=options.portRange, registryUrl=options.registryUrl) File "/usr/bin/Bridge", line 45, in __init__ self._RegisterWithRegistry() File "/usr/bin/Bridge", line 78, in _RegisterWithRegistry self.validSecs = self.registryClient.RegisterBridge(self.bridgeDescription) File "/usr/lib/python2.3/site-packages/AccessGrid/Registry/RegistryClient.py", line 53, in RegisterBridge self._connectToRegistry() File "/usr/lib/python2.3/site-packages/AccessGrid/Registry/RegistryClient.py", line 32, in _connectToRegistry self.registryPeers = self._readPeerList(url=self.url) File "/usr/lib/python2.3/site-packages/AccessGrid/Registry/RegistryClient.py", line 134, in _readPeerList f = opener.open(url) File "/usr/lib/python2.3/urllib.py", line 181, in open return getattr(self, name)(url) File "/usr/lib/python2.3/urllib.py", line 297, in open_http h.endheaders() File "/usr/lib/python2.3/httplib.py", line 712, in endheaders self._send_output() File "/usr/lib/python2.3/httplib.py", line 597, in _send_output self.send(msg) File "/usr/lib/python2.3/httplib.py", line 564, in send self.connect() File "/usr/lib/python2.3/httplib.py", line 548, in connect raise socket.error, msg IOError: [Errno socket error] (110, 'Connection timed out') ----- Thanks in advance!
