[arch-general] avahi problem

[Jochen Maes (Gcool)]

Are you running a firewall on the Arch box (or elsewhere in the
network) through which the avahi traffic has to pass? As I understand
it (various similar issues found through Google), you need to
explicitly allow mulitcast DNS traffic (udp 5353) for this feature to
work.
