It happens on every system.  They are all wired but various hardware.   
I can't believe that all those various network cards have driver issues.
Most of them are running Ubuntu 8.04LTS, but the one time I tested  
9.04 it showed similar behaviour.

If it was the switches, which are homogenous, then why would the Macs  
still see Bonjour advertised services?
Or is their software stack different enough that's a red herring?
The Macs always see each other, they only see a linux boxes after that  
box has it's avahi-daemon restarted.

Yes, that is what is happening. Apologies if the previous explanation  
was unclear.


I'll pull out Wireshark when I get a minute and see what I can see.  I  
wish I had a working network to contrast it to.
