I was just looking at that. The weird thing is the following: http://www.freebsd.org/cgi/cvsweb.cgi/src/contrib/ipfilter/tools/ipmon.c?rev=1.4.2.2 #ifndef LOGFAC #define LOGFAC LOG_LOCAL0 #endif In the contrib/ipfilter/Makefile it is set to security, but...freebsd builds with src/sbin/ipf/ipmon and there it is indeed LOG_LOCAL0. So either you could request docfix or Makefile fix. There's probably a reason why it's set hardcoded like that to LOG_LOCAL0. -- Mel Problem with today's modular software: they start with the modules and never get to the software part.
