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.

Style clean-up: * All variables are now embraced: ${foo} * All comparisons against some value now take the form: [ "${foo}" ? "value" ] where ? is a comparison operator * All empty string tests now take the form: [ -z "${foo}" ] * All non-empty string tests now take the form: [ -n "${foo}" ] Submitted by: jkh 1999-08-25 18:01:45 +02:00			`sysctl -w ${var}`
