Hi,

with a help of Michael, I've investigated this problem down to its rootcause, which appeared to be a misbehabing Avahi daemon.


If in one console the following command is being running:
    avahi-publish -s test _test._tcp 0

The following command running in another console prints nothing:
    avahi-browse -rt _test._tcp

As I'm not very familiar with Avahi troubleshooting, any help or ideasare welcome.
