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 at bridgeserver ~]$ Bridge -nFACYT-UC -lVenezuela
