Add two features: log_in_vain: log_in_vain turns on logging for packets to ports for which there is no listener. rc.sysctl: A generic way to set sysctl values. It reads /etc/syslog.conf and sets values based on that. No /etc/syslog.conf has been checked in yet, and I've not added this to the makefile yet until I get more feedback.

Make ipfilter, ipnat, ipmon, and ipfs behave more like the old rc. o group them together so they run one right after another o use the NetBSD supplied ipfs script instead of tacking it on to the end of ipnat o Load the ipl module in ipnat and ipfilter, if it's not already loaded o In ipmon and ipnat show a warning if neither ipfilter nor ipnat is enabled or the ipl module is not loaded, and exit Approved by: markm (mentor) (implicit) Tested by: leafy <leafy@leafy.idv.tw> 2003-04-24 08:20:47 +00:00			`# REQUIRE: root`

Luke Mewburn has indicated that they (NetBSD) are not interested in keeping the scripts under rc.d in sync with us. So, begin removal of NetBSD specific stuff (which made our scripts more complicated than necessary), starting with the NetBSD KEYWORD. 2004-01-17 10:16:38 +00:00			`# KEYWORD: FreeBSD`

Fix two typos. Using "-eq" instead of "=" in a [ caused an error when an entry in /etc/sysctl.conf didn't exist. Fixing this exposed a minor typo "exits" vs. "exist". However, there doesn't appear to be any provision to run this with the "lastload" argument, meaning that the error will never appear. 2002-10-25 23:02:54 +00:00			`elif [ "$1" = "last" ]; then`
