#!/bin/sh # # Contributed to the OpenVPN project by # Douglas Keller <doug@voidstar.dyndns.org> # 2002.05.15 # # Modified by # Michel Pereira <michel@michel.eti.br> # 2005.05.16 # To install: # copy this file to /etc/rc.d/rc.openvpn # shell> chmod +x /etc/rc.d/rc.openvpn # shell> mkdir /etc/openvpn # make .conf or .sh files in /etc/openvpn (see below) # Author's Notes: # # I have created an /etc/init.d init script and enhanced openvpn.spec to # automatically register the init script. Once the RPM is installed you # can start and stop OpenVPN with "service openvpn start" and "service # openvpn stop". # # The init script does the following: # # - Starts an openvpn process for each .conf file it finds in # /etc/openvpn. # # - If /etc/openvpn/xxx.sh exists for a xxx.conf file then it executes # it before starting openvpn (useful for doing openvpn --mktun...). # # - In addition to start/stop you can do: # # service openvpn reload - SIGHUP # service openvpn reopen - SIGUSR1 # service openvpn status - SIGUSR2 # # Modifications: # # 2003.05.02 # * Changed == to = for sh compliance (Bishop Clark). # * If condrestart|reload|reopen|status, check that we were # actually started (James Yonan). # * Added lock, piddir, and work variables (James Yonan). # * If start is attempted twice, without an intervening stop, or # if start is attempted when previous start was not properly # shut down, then kill any previously started processes, before # commencing new start operation (James Yonan). # * Do a better job of flagging errors on start, and properly # returning success or failure status to caller (James Yonan). # # 2005.04.04 # * Added openvpn-startup and openvpn-shutdown script calls # (James Yonan). # # 2005.05.16 # * Customized to run on Slackware # (Michel Pereira) # Location of openvpn binary openvpn="" openvpn_locations="/usr/sbin/openvpn /usr/local/sbin/openvpn" for location in $openvpn_locations do if [ -f "$location" ] then openvpn=$location fi done # Lockfile lock="/var/lock/subsys/openvpn" # PID directory piddir="/var/run/openvpn" # Our working directory work=/etc/openvpn # Check that binary exists if !
