Given the importance/need for many of us to statically assign bridge ports, will this functionality be available in AG3?
Can you elaborate this point more? What is currently in AG3 is this: - A Bridge can be run with a particular port range specified. The person running the bridge will have to ensure that these ports are open for udp through their firewall. - A user will see which bridges are available, and can view the hostname and port range used by each. The user can then decide which bridges to use, and pass this information to a network admin to open ports accordingly. Questions this leaves open: - What should the default port range for a bridge be? How about 50000-50200? This would ensure that bridges will, by default, all use the same (relatively) narrow port range. - Is this sufficient for your local networking needs? There may be something additional implied by 'statically assign bridge ports', and I'd like it to be explicit so I can address it. Tom On 4/19/06 11:44 AM, Todd Zimmerman wrote:
Agreed. We've been bridging our entire venueserver for years. We only run into issues when we overlap venueserver and venue configs.

Bridging an entire venue server is supported just fine in my experience. There may be problems if the config specifies an overlapping set by, say, specifying a venue server and individual venues on that server; these should be regarded as mutually exclusive options and, I think, in most practical situations, they are.

So basically I have to manually bridge each room. In my config file I tried to set the entire VenueServer to only use a range of ports, then I entered ports for the rooms I wanted to configure statically. But I still came across that "Address already in use" problem.
For example, I have the VenueServer set to 5000-5200 and 4 Venues to 5202 on up.
I don't specifiy the ports for the venue server overall. Beside I think bridging a whole venue server is not that well supported. You have to specify the ports for each venue seperately. If you refer to the ports of the VenueServer itself, these are configured through the VenueServer configuration. As fas I know through the VenueServer.cfg file, but I didn't succeed in configuring it yet.

I am doing basically the same. I restrict the range of the ports for unicast for a specific venue.
Config-File example:
[https://rusagvideo.rus.uni-stuttgart.de:8000/Venues/000001026deebc1400c0006c...]
type=Venue portMin=50096 portMax=50099
One of the problems rising with this configuration method is that normally AG selects ports on a random pattern put of the range you specified in the config file. Ports for rat and vic are allocated sequentially. So first rat gets assigned 50096 for example. When the port for vic should be determined, it can happen due to the nature of the random allocation that for vic also 50096 is initially selected. This of course leads to a "Address already in use" error. I avoided the problem by patching the AccessGrid files responsible for port allocation to keep a list of ports which are in use and have the allocation algorithm first check if a port the algorithm wants to allocate isn't in use yet. Otherwise you have to restart the bridge server until you don't get the "address already in use" error to be sure you really have video and audio correctly bridged.

Which version of AG software are you using for BridgeServer and VenueServer? Can you post your full bridge cfg file?
AG 2.4. Attached is the config file. Worth noted is that I no longer get those python errors, however, now when I start it, several of the venues aren't bridged because the bridgeserver says the address is already in use
