nmap both locally and via another machine on the lan seems to imply 5353 is
/root> nmap -sU -p5353 10.101.43.10
Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2007-01-03 12:50 WET
Interesting ports on 10.101.43.10:
PORT STATE SERVICE
5353/udp open|filtered unknown

Now we may be getting somewhere. No, it doesn't work:
/root> /usr/local/bin/avahi-resolve -n linux-robert.local
Failed to resolve host name 'linux-robert.local': Timeout reached
> Does "dig -p 5353 @126.96.36.199 yourhost.local" work?

I got the message:
Jan 2 07:05:31 linux-robert avahi-daemon: New relevant interface
eth0.IPv4 for mDNS.
I think multicast is enabled, but if there's somewhere in /proc or something I
can check let me know.

My guess is that since its a service allowing other machines to access a
directory under /home , it lets you know that its been succesfully published
when the desktop comes up. Really I don't need to use kpf - it just seemed
like an easy way to test avahi . My goal here is to get my feet wet for a
linux embedded project using avahi .
