Steps to reproduce: I have a simple application that joins a group and listens for multicast traffic. I start 1 instance on group 239.99.99.1 port 9001 and another instance on group 239.99.99.99 port 9001. I then start an application that sends packets to 239.99.99.1 port 9001. BOTH of my receiving process get the packets. This is different than what I see on Win32 and Solaris, where both the group and the port must match to get the packets. I can provide a simple Java app that demonstrates this, send me an email if you want it. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
