multicast addr and receiver (portbase) port ?

You really should try with the most recent version of udpcast to check
whether this problem has already been solved over the past 2 years.
Additionally, I would recommend to triple-check the switch'
configuration. From my experience in 99 out of 100 cases there is a
network misconfiguration when experiencing problems with udpcast.
Just my 0,5?.
Thanks for your answer; as I wrote, latest version (20100130) does the
same. This is why I had to look at the code and make this dirty hack.
I'm pretty sure the Dell switch is culprit, but the multicast
configuration looks good, and with the modified version of the sender
multicast and igmp work as expected.
Do you think it is acceptable for the sender to query the multicast
data group itself as the general rule or could it bring some more
problems ? ( the later case would require my patching of the code with
each new release ...). Maybe Alain is the only one who can state
