Hi Jose,

 

I can join the stream in CT with mcfirst.

 

Received 1316 bytes from 138.237.40.197 after 947.145 ms (ttl/hops 20)

131600 bytes (payload) and 100 packets received in 0.947 seconds

Average rate: 1418.615 kbits of payload per second

Estimated average rate including all headers: 1448.798 kbits per second

I am now sending a VLC UDP stream on 233.73.103.151 port 1234 with VLC version 0.8.6h. Can’t remember if this was a “solid” version, but at least wireshark is reporting the correct TTL=32.

 

Do let me know if you can’t see it.

OK – so I owe dinner and several libations of choice to several people…  J

 

Has anyone noticed that the latest VLC version (1.0.5 and maybe others) appears to set TTL = 1 on UDP streams no matter what you set it to in the GUI? Anyone else out there come across this problem and knows the best workaround? Just did a wireshark on the stream and every frame has ttl=1 even though I set it to 32.

 

Many thanks to all,

 

José Feghali

Scott,

 

Ooops… Operator error, faulty TTL…

 

Could you please try again?  DVTS 233.73.103.152 : 8000

 

Many thanks,

 

José

Colleagues,

 

Looks like we might be getting closer to the problem preventing us sending mcast from here. Could you please see if you can receive the following:

 

DVTS – 233.73.103.152 port 8000

 

Many thanks,
