I'm not sure what it was exactly in 2.1, but `netstat -g' on my 2.1-stable box (from about a week or two ago) says: gary@palmer:~> netstat -g no multicast routing compiled into this system ^^^^^^^ gary@palmer:~> Multicast reception/transmission is enabled by default, but you need to add options MROUTING # Multicast routing to your kernel if you want to route multicast packets between interfaces. Perhaps you were looking for ``netstat -s'' which would (amongst other data) give you: igmp: 0 messages received 0 messages received with too few bytes 0 messages received with bad checksum 0 membership queries received 0 membership queries received with invalid field(s) 0 membership reports received 0 membership reports received with invalid field(s) 0 membership reports received for groups to which we belong 0 membership reports sent (and no, I don't have an MBONE feed :-( ) >A fairly good indication we have something wrong. How do you enable >multicast in 2.1 ? I did not see any config parameters related to multicast ? See above. Hope this helps Gary
