Same subnet?
Switch?
Yes and Yes.
Tried same MACHINE even.
Here's what I send to Matt last week:
Well, I did more testing tonight with a network trace running.
2 machines running media server and another running the client
gtjtp is a IBM Thinkpad 770Z with 2 network interfaces (gtjtp0, gtjtp1) running Win2kPro
ernie is a dual 400mhz PII machine with 2 network interfaces (ernie0, ernie1) running Win2kServer
ralph is the source machine, a dual 1.8ghz P4 XEON with 1 network interface running Win2kServer
I won't bore you with the ethernet, ip and udp headers but here's the exchange when I run "Search..." from ralph.
-->GetMediaServerAddress
<--MediaServer:gtjtp0.peakin.com:80
<--MediaServer:ernie0:80
<--MediaServer:gtjtp0.peakin.com:80
<--MediaServer:ernie0:80
ernie0 and gtjtp0.peakin.com are both valid names and ralph can resolve them to ip addresses (from the hosts file, not dns).
I set up the machines so ernie would only return a host name and gtjtp would return fully qualified domain names to see if there was a difference. There wasn't.
Notice that the 2 messages from each machine came back with the same host name instead a host name for each of the interfaces on the media server machines. Are 2 responses sent because the media server recognizes it's bound to 2 interfaces or because it got 2 broadcast requests, 1 on each interface? Either way, they shouldn't be duplicates.
I get 4 pop up boxes with the "Invalid Media Server Information" message.
Another little tidbit... If I turn on ralph's second interface and run the exact same test, I get 8 popup messages instead of 4. I'm guessing that since the second interface is also getting the multicast responses, MC is seeing double responses. You might want to make the responses unicast directly back to the source instead of multicast.
Finally no combination of machines and/or interfaces get's me by the "Invalid" message. Even if I run both client and server on the same machine with 1 interface and nothing else running on the local network I still get the message.
All machines are running 9.0.85 and show media server version 1.0.135 and using the library manager, I can catalog and connect to all of the media servers with the "m01p://" url.
Hope all this helps...remy
