===== preparations =====
  * Setup of linux: using Fedora 10 beta i386 since it will provide all needed software as packages. Already did all this compiling the software myself, this time will use it off the shelf.
  * make sure the host is resolvable via files: %%echo '10.0.22.19 fed10 fed10.fluxcoil.net' >>/etc/hosts%%
  * setup in a vmware 2.0 virtual machine
  * update to latest versions
