Pokign around inside gdb, the src and dest addresses on the packets it is trying to send out look ok to me (src is the ip address on the interface and dst is the mDNS mcast group -- 224.0.0.251). Any idea on how to debug what is happening once the sendmsg system call is made? I would assume sendmsg would get a failure code if there was something wrong with the packet it got sent and it didn't know where to send it, etc.? I even took wireshark and looked at the physical ethernet interface just to make sure it wasn't get sent out on the physical interface untagged and the packets didn't show up at all (either vlan tagged or not). Since none of the previous versions work for me, its possible that this has something to do with my vlan setup, but i'm not not quite sure where to look from here. </pre> </blockquote> <pre wrap=""> Is it possible to try without VLANs on this system? </pre> </blockquote> Yeah, I plan on trying that, I just have to schedule a down time for this since there is other stuff running on the box.  I'll try and get that done tonight. <blockquote cite="mid20061030023908.GB3174@bur.st" type="cite"> <pre wrap=""> Also what does 'netstat -gn' say? does it show it as having jointed the multicast groups on these interfaces? </pre> </blockquote> It definitely joins the mcast group on all of the interfaces.

So far I haven't had much luck with 0.5 since that was before it went into the FreeBSD port system and its looking for some older libs and such that I don't have installed. Is there anything I can look at/debug that would help pinpoint where the problem is? Thanks. Keith Mitchell wrote: No, I never see anything go out even on a browse. The browse just lists things as they are announced by the other system periodically. Trent Lloyd wrote: Hi Keith, Do you see *any* packets sent out by avahi at all? (e.g. if you do a browse do you see packets go out? It's possible there is a problem with the FreeBSD support there has been a few changes etc and unfortunately its hard to track 100% cross platform ability. I would appreciate it if you could go back a few versions and try it, e.g. give 0.6.10, 0.6.5, 0.6.0 and 0.5 a test and let me know the first you have success in (once you find that if you could then edge forward until you find the release that broke it it would be double plus good) Following that I'll see what I can do to try fix it for you.
