Public bug reported:
I am using Kubuntu 10.10 for multicast data packets. I am sending multicast
data packets from a windows machine which is listened for on my Kubuntu machine.
With wireshark I have confirmed that the packets are reaching the Kubuntu
machine. Also I have confirmed on the windows machine of my membership addition
to the multicast broadcast.
However, my c++ code is blocking on a receive from (recvfrom) function call,
but my code is not receiving the data packets at all.
I tried a lot of settings to get it to work. After a day of looking, I found
that flushing the ip tables, turning of the firewall and making my code listen
on INADDR_ANY, then only does it work, but if we Bind to a particular IP, it
does not work.
I think this is a bug because the code runs on the windows machine as is.
Also, I need to bind to aparticular IP since my LAN card has multiple IPs and I
also have multiple NICs.
Is there a way to make ti work with binding and possibly have this bug
fixed in Ubuntu/Kubuntu?
