[AG-TECH] Problems getting Unicast Bridge to run CentOS 5.0

It appears you are using the wrong syntax for the registry peer.

You should be using:

Bridge -p 20200 -u http://www.accessgrid.org/registry/peers.txt -n "<Bridge Name>" -l "<Location>"

	Example syntax:

Bridge -p 20200 -u http://www.accessgrid.org/registry/peers.txt -n "CQU-Bridge" -l "Rockhampton, Queensland, Australia" &

The syntax you are using is http://ag-server/registry/peers.txt, where it should be http://www.accessgrid.org/registry/peers.txt 

Hope this helps.

Hi All, 
I keep getting the following error each time I try to start the Bridge Server. 
I've checked that the hostname is both in DNS and in /etc/hosts, but always get the same error message. Any advice? 
$ Bridge 20200 -u http://ag-server/registry/peers.txt -n "CentOS Bridge" -l "Canberra" 
Traceback (most recent call last):
