How do I block the network access completely for a certain program with a blacklist or whitelist, whitelist prefered, with OpenBSD's pf(4)? My pdf reader, music player, video player, vim and much more shouldnt have access to networking at all. I remember it being possible with the Windows firewall program to choose a certain program to be completely networking-less. Is this possible with OpenBSD too? I couldnt find anything in the man pages or in the FAQ regarding this issue.
