Dear ALL, we are not able to receive all multicast packets on an interface, even after setting ALL_MULTI flag on that interface.Ether real doesnot show multicast packets, tcpdump doesnot show multicast packets, iconfig doesn't show tx increments for some specifc multicast ip addresses.We have a simulator which generates IGMP membership request,when we request destined to some addresses(224.0.0.1,224.0.0.4...), then it is responding fine, but for other addresses(224.0.0.23.224.0.0.22...) it is not reponding. please suggest some thing on how to debug this situation. thanks in advance lsreddy. -- _______________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup -- Kernelnewbies: Help each other learn about the Linux kernel.
