Hi, I installed FREEBSD 4.3-RELEASE on my machine recently, but I start to wonder if it support multicast for IPv4 by default kernel configuration. I tried mtest on a FREEBSD 2.2.8-RELEASE box (192.168.24.78) and result is as follows: > % mtest > multicast membership test program; enter ? for list of commands > j 224.1.1.1 192.168.24.78 > group joined then I can successfully ping the multicast address (224.1.1.1) from any other machine: > %ping -c 1 224.1.1.1 > PING 224.1.1.1 (224.1.1.1): 56 data bytes > 64 bytes from 192.168.24.78: icmp_seq=0 ttl=255 time=0.438 ms > --- 224.1.1.1 ping statistics --- > 1 packets transmitted, 1 packets received, 0% packet loss > round-trip min/avg/max/stddev = 0.438/0.438/0.438/0.000 ms However, when I did the same on a FREEBSD 4.3-RELEASE one (192.168.24.86): > %mtest > multicast membership test program; enter ? for list of commands > j 224.1.1.1 192.168.24.86 > group joined while at this time any ping to 224.1.1.1 from another machine couldn't get any respond. Do I need to compile a new kernel which support multicast for IPv4, and if so how can I make it? Your advice appreciated.
