#
|
|
# Usage:
|
|
#
|
|
# If you are running a distribution that has a directory called /etc/rc.d/init.d or one
|
|
# called /etc/init.d or you are running Slackware then simply cd to the directory
|
|
# containing this script and run it.
|
|
#
|
|
# ./install.sh
|
|
#
|
|
# If you don't have either of those directories, you will need to determine where the
|
|
# SysVInit scripts are kept on your system and pass the name of that directory.
|
|
#
|
|
# ./install.sh /etc/rc.d/scripts
|
|
#
|
|
# The default is that the firewall will be started in run levels 2-5 starting at
|
|
# position 15 and stopping at position 90. This is correct RedHat/Mandrake, Debian,
|
|
# Caldera and Corel.
|
|
#
|
|
# If you wish to change that, you can pass -r "<levels startpos stoppos>".
|
|
#
|
|
# Example 1: You wish to start your firewall in runlevels 2 and three, start at position
|
|
# 15 and stop at position 90
|
|
#
|
|
# ./install.sh -r "23 15 90"
|
|
#
|
|
# Example 2: You wish to start your firewall only in run level 3, start at position 5
|
|
# and stop at position 95.
|
|
#
|
|
# ./install.sh -r "3 5 95" /etc/rc.d/scripts
|
|
#
|
|
# For distributions that don't include chkconfig (Slackware, for example), the
|
|
# /etc/rc.d/rc.local file is modified to start the firewall.
