In all of Google I found just one of these; on FreeBSD. This machine - rebooted several times in the last 18 months - had never had this (in /var/log/messages) before; and no changes being done to the software, permissions or the machine at all. A simple reboot after power failure.
This is the complete message: Nov 18 12:39:50 mybox pflogd[3586]: Failed to initialize: /dev/bpf0: Permission denied Nov 18 12:39:50 mybox pflogd[3586]: Exiting, init failure OpenBSD 3.7 stable Any hint ? Uwe
