Hello, I am trying to run a script to listen to a multicast feed internally. The script is very basic in that it is just listening, not doing anything with the data just listening. I added some print statements to see the progression of the script and it seems to get hung up on the while loop. I saw this example in CPAN so I figured it should work ok, please take a look and if anyone could give me some hints as to what I might be doing wrong that would be great. Also, the multicast is leaving on a specific port, does that matter, is there anyway I can specify which port to listen on for this mcast traffic? Thanks again, Javier
