[avahi] Avahi not working on SuSE Linux 10.1

[John Calcote]

Trent,

Thanks for the response. I killed mdnsd and then started the avahi daemon as per your instructions (with the --debug option). 

Here's the avahi-daemon console output:

jmc-linux:/home/jcalcote # avahi-daemon --debug

Got SIGINT, quitting.

During this session, I ran avahi-publish-service in another ssh shell:

jcalcote at jmc-linux:~> avahi-publish-service "John's Apache" _http._tcp 80
Established under name 'John's Apache'
<Ctrl-C break after several seconds entered at keyboard>
Got SIGINT, quitting.

While the publish session was running, I ran avahi-browse in yet another ssh shell:

jcalcote at jmc-linux:~> avahi-browse _http._tcp
<Ctrl-C break after several seconds entered at keyboard>
Got SIGINT, quitting.


That's about all. When I follow this same procedure using the Apple tools (mdnsd is the daemon, and dns-sd is the publish browse tool) it just works. I'm sure there's just something I'm not aware of. Does this information help you see what it might be?

Thanks,
John

Hi John,

When you say it works, what utility were you using to browse
for services?

Could you also paste the output of 

avahi-daemon -k (kill running daemon)

then run:
(as root) avahi-daemon --debug

And then attempt to do service discovery/publishing, and send me the log
(via private e-mail if you like rather than to the list)

Cheers,
Trent
