Hi everyone,

I'm having some problems with multicasting an UDP packet
on FreeBSD 1.6. I'm using C code which is similar
to the attached mtest.c. The problem is that on
Linux and Solaris, I use the following line to join
a the multicast group:
setsockopt(s, IPPROTO_IP, IP_ADD_MEMBERSHIP ...)

However, when this code is run on NetBSD, it doesn't join the multicast
group. The code works for the all-hosts group (224.0.0.1), but not any
other multicast group.

So what's the proper may to join a multicast group in NetBSD 1.6?
Does anyone know of any code in C which does Multicasting that I can have
a look at ?

All help is appreciated!

 Andreas R.
