I'm pretty new to this whole mailng list thing, so I hope I picked a
good list to start with.
I'm trying to get a FreeBSD box (2.1.0-SNAP) running some of the MBONE
tools. (sd, vat, nv, etc) It doesn't seem to want to do it, though.
If I look at the ethernet device (ep0) I see
ep0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX> mtu 1500
inet 128.143.71.29 netmask 0xffffff00 broadcast 128.143.71.255
ether 00:20:af:ed:e7:61
No matter what I do, though, I can't get it to say MULTICAST.
Of course, the loopback is multicast, but I don't think that helps.
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
I have an mrouter on my subnet, and I have recompiled the kernel with
the "options MROUTING" in it.
The ep0 device works fine. I can even do point-to-point links with
nv, wb, etc. If I try to run sd or vat, I get:
IP_ADD_MEMBERSHIP: Can't assign requested address
I don't know what that means. Of course, Van Jacobsen isn't going to
give me any source code, so I can't go look up what that means,
either! He won't even write frigging man pages! Grrr. Ok, I feel
better now.
Anyone have any ideas?
Thanks,
Paco
