Jimmy, I was able to multicast with Mike Daley earlier just fine. Something 
must be dropping (rockies?) your sources, etc. closer to you I think.

I'm not able to get your multicast source on that address (233.2.171.245/59966) 
with that vic. I would have to say the problem is in the U.S., at least for 
you, because Mike and I had no problems and I just tested:

Multicast between LSU and NCSA, no problem
Multicast between LSU and westgrid, no problem
Multicast between LSU and APAG, no problem
ARSC, no problem...
Kisti.. No problem...

You have a bridge by chance?

(easy to test this way, setup a multicast source on one machine A, then take 
another machine B and bridge out to people's bridges with machine B and see 
when it breaks, it's a rough guide, but it's easy to do in fact, you can see 
when there are one-way issues this way and which it is).. If you add a source 
on the machine B, you get to test it both ways. Be sure to test locally if you 
can so you know your sources are working on both first... Then.. Bridge out. ;-)

So to test multicast to me, setup multicast sources on A, do bridging on B and 
hit LSU's bridge with the B one. See if you see yourself and your multicast 
sources. If not... No multicast somewhere between us, work yourway backwards 
through the other USA bridges closer to you... Helps if you know the networks, 
I'm not so good at that. This is the other way to vaguely test....

A real network person would do mtraces and stuff (I can't mtrace from inside my 
campus, but could do it on other external routers, I just keep forgetting the 
commands the few times I've done it).

Subject: [AG-TECH] New HD-Vic 1.1 Beta trouble shooting.

If someone could download and install the beta version of HITLab's HD vic 1.1 
and then connect to 233.2.171.246/59966 (Cardiff Venue at Manchester's VS) it 
would help troubleshoot why Cardiff and Utah is unable to see each other's 
stream. We each know that within our perspective countries, the feeds are 
viewable but for some reason, it's not getting across the Atlantic. I don't 
think that it's passing through the Bermuda Triangle. The HIT Lab in NZ was 
able to see it earlier.

You can get the new beta vic at http://www.hitlabnz.org/wiki/Access_Grid_-_HD 
<http://www.hitlabnz.org/wiki/Access_Grid_-_HD>

Thanks in advance.
Jimmy
