Quoting Bill Marquette <bill.marquette@ucsecurity.com> (from Mon, 6 Jul 2009 20:14:02 -0500 (CDT)): > I'm trying to run Avahi in a jail, much the same as Alexander > Leidinger in this email from late last year > http://www.mail-archive.com/freebsd-jail@freebsd.org/msg00587.html. > I couldn't find any replies to that thread and it seems that I'm > running into the same issues - the service announcements make it on > the wire and the other devices in the network see them. So far I have nothing working. I assume that the mcast traffic is not arriving at all IPs. <wild guess>Either because on overly restrictive jail check, and/or just because there's no code which is distributing the traffic to all IPs.</wild guess> It seems kern_jail.c is a place to check if there's some code which handles this. Maybe prison_check_ip[46] if mcast is on top of this, or something new to write if mcast is a different "AF". Again, this is a wild guess, I don't have enough understanding of the network code in the kernel to even make educated guesses about the real reason.
