Hello.\n\nI'm trying to set multicast routing on linux box running slackware (kernel\n2.4.26). After research i found smscroute - exactly what I was looking for\n- small program to put static multicast routes to kernel.\n\nBasically what I need is to make some traffic multiplication on LAN\ninterfaces (802.1q logical interfaces) to send some multicast video stream\nto them.\nThe smscroute worked excellent on my test systems:\n- slackware\n- debian unstable\nWhen I put some multicast packets on eth0, I could multiplicate this packets\non eth1.2 eth1.3... interfaces by typing:\n\nsmcroute -d\nsmcroute -a eth0 192.168.0.1 220.127.116.11 eth1.2 eth1.3...\n\nafter doing tcpdump -ni eth1.2 I could see multicast packets.\n\nBut it there are same problems on target box (slackware server with 2 intel\ne1000 cards). The test systems and target system have:\n- the same kernel (2.4.26)\n- the same smcroute binary\n- they also have the same number of logical interfaces\n- even the same aliases...\n- only difference is NIC chipset -\non test systems: 8139too, on target system: e1000\n\nOn target system smcroute daemon is running, there are no errors in syslog.\nAlso,\n\ncat /proc/net/ip_mr_cache\ncat /proc/net/ip_mr_vif\n\nshows, that packets are forwarded. But I can't see them via tcpdump.\n\nI don't have aby idea where is the problem. This is driving me nuts, so\nplease, HELP!\n\nI can't change target server, because it is working correct on its main\nfunction - NAT for clients. It is MSI server Pentium4 CPU 2.40GHz.\n\nI found in google, that somebody had similar problem, here is the link:\n[URL]http://tinyurl.com/5tx79[/URL]\nbut the solution with MTU not working (the MTU are the same on all\ninterfaces)\n\nthanks for ANY help\n\nregards.
