Linux OSX file sharing

Getting my new Macbook to see my main Linux box turned out to be rather complicated.
I followed this guide to begin with. I just had to change a few names for a Mandriva system:

• the config file is /etc/netatalk/netatalk.conf
• to add directories that can be accessed use /etc/netatalk/AppleVolumes.default

This provided instructions on using howl, but that has been deprecated in favour of the avahi that is installed with Mandriva. The rest of the instructions I used were these, including the creating of

• /etc/avahi/services/afp.services (a file with this name now comes with Mandriva 2009.1)
  

Apple advise that you need to open port 548 on your firewall.
