Alain,
I'm trying to perform a packet capture of the data transmitted by udp-sender using Wireshark and am running into the exact same problem encountered by Lance 8 years ago. (posting listed below.)
What information can I provide to help debug this issue?
Also, can you tell me if the multicast data sent includes a sequence number and does the receiver have the ability to filter out duplicate multicast frames?
Regards,
Chris

I have used the lattest version of udpcast (udpcast-20050226.tar.gz) as well as used ethereal version 0.10.12 and I still get the "Bogus IP header length (0, must be at least 20)" I will continue to try this on different Platforms with different network switches and see what I get.
