Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-netdev@oss.sgi.com Precedence: bulk Return-Path: X-Orcpt: rfc822;netdev-outgoing Content-Length: 577 Lines: 18 Dear sirs, I'm working on some multicast applications for an university exam. There seems to be a change in the way the linux kernel deals with multicast in multihomed host. All the software I tested (both mine and third parties') does not work if the host is multihomed. The packets seems to go nowhere and are invisible to the command "tcpdump ip multicast" too. This does not happen with kernel 2.2.5, for instance. My question is: is there a change in the kernel multicast code after version 2.2.5? If so, how can I get more information? Thanks in advance, Antonio
