Checklist to ensure that zeroconf will work: 1) Install Avahi, at least version 0.3 2) compile kdnssd-avahi and install it to replace 'stub' libkdnssd.so provided by kdelibs 3) check /etc/nsswitch.conf and ensure that there is 'mdns' before 'dns' in line starting with 'host:'. It should be something like: host: files mdns dns 4) ensure that avahi-daemon is being started in initscripts 5) for testing: use kpf kicker applet to publish a directory, then open 'zeroconf:/' URL in konqueror. You should be able to see a local webserver with that published dir. For more information go here http://wiki.kde.org/tiki-index.php?page=Zeroconf%20in%20KDE
