#
# A modification of the CS Server startup script, to run the server
# as a non-root user.

# ===========================================
#
# What you need:
#
# Linux
# awk 
# screen
# srcds & cstrike-files OR
# 
# YES, this script works fine with fine with CS 1.6
# 
# How to use:
# 
# Edit the DIR-var to fit your system (just contains the path to the dir that contains hlds_run)
# Edit the PARAMS-var to fit your needs 
# Edit the CS_USER-var to the name of the user that will run the server
#
# How to see the server-console:
#
# Just type in: screen -r srcds (or whatever you set $NAME to)
# More info about screen can be found by typing "man screen"
#
# The easist way is to use this script simple as a start-script for your server
# If you want to use it as a script to start the server at boot-time:
#
# When this is done, copy the file to /etc/rc.d/init.d (or whereever your system stores the
# scripts for starting the services
# Now you can link the script to your runlevel-dir, here's an example for runlevel 3:
# (THIS IS FOR DEBIAN! If you use e.g. Redhat you must change these dirs!!!)
#
# ln -s /etc/init.d/hlds /etc/rc3.d/S90hlds
# ln -s /etc/init.d/hlds /etc/rc6.d/K50hlds
#
# Or use it manualy like: 
# /etc/rc.d/init.d/hlds start 
# /etc/rc.d/init.d/hlds stop 
#
# If you don't want to start the server as root you have to change this:
# add the var CS_USER and uncomment it
# change the lines at the "start-block"
# 
# You must be logged in as this user to re-attach the screen!
#
# DOC by jwm (jwm@counter-strike.de)

# The user that will run the server
CS_USER=source

# Leave this alone.
NAME=srcds

PATH=/bin:/usr/bin:/sbin:/usr/sbin

# DON'T FORGET TO CHANGE THE PATH TO YOUR NEEDS!
DIR=/games/steam/source

# Leave this alone.
DAEMON=srcds_run

# Internet-server:
PARAMS="-game cstrike +map de_dust +maxplayers 16 -autoupdate"

# Leave this alone.
