Has anyone managed to get the programs 'wb' and 'sd' (from ftp.ee.lbl.gov)
running on a local multicast network using FreeBSD? Is there a
step-by-step guide on how to get it working?

When I try to run 'sd' all I get is:

IP_ADD_MEMBERSHIP: Can't assign requested address

Although according to 'netstat' it does seem to have added an entry
to the routing table:

224.2.127.255    link#2             UHLW        0        0 

Although output from 'netstat -ns' shows the following:

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

Am I just being stupid? I couldn't see anything I should enable in
the kernel config.

Any help would be appreciated....
