[avahi] Service discovery not working...

[snott]

Hello avahi-users,

I installed avahi on my FreeBSD box (without X11 etc tools, Python bindings
only) and by default it publishes a _ssh._tcp service.  Using avahi-0.6.23
from ports

When I run the PythonBrowseExample script from here, modified to find
_ssh._tcp

http://avahi.org/wiki/PythonBrowseExample

(tokyo-cc2 is localhost on 10.151.2.4)

# ./browse-ssh
Found service 'tokyo-cc2' type '_ssh._tcp' domain 'local' 
service resolved
name: tokyo-cc2
address: 10.151.2.4
port: 22

Likewise on the "other" box on 10.151.2.5 - finds itself but not the other

# ./avahi-browse-example 
Found service 'tokyo-cc3' type '_ssh._tcp' domain 'local' 
service resolved
name: tokyo-cc3
address: 10.151.2.5
port: 22

I've verified mDNS packets are being passed around, although I'm not well
versed in the protocol:

# tcpdump ip multicast | grep 10.151.2.5 
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

I also tried the pybonjour python browser with libdns bindings with the same
result.
As you can see, it is finding an iphone on the network somewhere fine, so I
don't think its the switch :)

# python browse_and_resolve.py _ssh._tcp 
Service added; resolving
Resolved service:
  fullname   = tokyo-cc2._ssh._tcp.local.
  hosttarget = tokyo-cc2.local.
  port       = 22

Service added; resolving
Resolved service:
  fullname   = Vonny\032Juliana\226\128\153s\032iPhone._ssh._tcp.local.
  hosttarget = Macintosh-001B63EAFEBB.local.
  port       = 22
Service removed


Any suggestions??? 

Thank you,
Skye
