Compile and install it with:

./configure
make
sudo make install

If you want the service to start with you system run:

sudo cp contrib/initscripts/ubavahid /etc/init.d/
sudo update-rc.d ubavahid defaults
sudo /etc/init.d/ubavahid start

If you have ubavahid, ubd and avahi-daemon (installed by most desktop versions of Linux) running on the same machine
you have to add the following line to your /etc/avahi/avahi-daemon.conf in the [publish] section:

publish-addresses=no

This prevents avahi-daemon from announcing the hostname with the newly created ip address.

ubavahid uses syslog to log its actions.
