Recompile your kernel with bpf-support (grep in LINT for it and copy that line into your normal kernel-config-file). See the handbook on how to recompile kernels if you're not familair with it. After that, go to /dev and do ./MAKEDEV bpf (or something similair) and you're in! Edwin -- Edwin Groothuis | Interested in MUDs?
