====== Left 4 Dead 2 server quick start ======

//Note: if using modern Ubuntu or Debian 32-bit, first do: //''sudo apt-get install lib32gcc1''

===== Auto-install script =====
<code=bash>
wget -c http://storefront.steampowered.com/download/hldsupdatetool.bin || exit
chmod +x hldsupdatetool.bin || exit
./hldsupdatetool.bin || exit

test -e go || cat <<EOL > go
export RDTSC_FREQUENCY=2500.000000
cd left4dead2
./srcds_run l4d -autoupdate +hostport 27015 +ip 0.0.0.0 +exec server.cfg
EOL
chmod +x go

mkdir -p left4dead2/left4dead2/cfg
ln -s left4dead2/left4dead2/cfg/server.cfg .
ln -s left4dead2/left4dead2/motd.txt .
ln -s left4dead2/left4dead2/host.txt .

cat <<EOL > server.cfg
hostname "ZOMBONI 9003"
rcon_password "XXXXX"
z_difficulty "advanced"
sv_region 0
sv_gametypes "coop, versus, survival, scavenge"
sv_allow_lobby_connect_only 0

echo './steam -command update -game left4dead2 -dir .' > update
chmod +x update

./update ; ./update


</code>

===== Manual install and config =====

Get steam:
  wget http://storefront.steampowered.com/download/hldsupdatetool.bin
  chmod +x hldsupdatetool.bin
  ./hldsupdatetool.bin

Install:
  ./steam -command update -game left4dead2 -dir .

Three useful files:
  left4dead2/left4dead2/cfg/server.cfg -- Server config (doesn't exist by default)
  left4dead2/left4dead2/motd.txt -- Message of the day (either text, or a URL to a page)
  left4dead2/left4dead2/host.txt -- Banner for the server (a URL to HTML that fills banner-like dimensions)

Launch script:
  export RDTSC_FREQUENCY=2500.000000
  cd left4dead2
  ./srcds_run l4d -autoupdate +hostport 28015 +ip 0.0.0.0 +exec server.cfg

Sample server.cfg (locks the server down to so it can only be requested directly (see below)):
  hostname "ZOMBONI 9003"
  rcon_password "XXXXX"
  z_difficulty "advanced"
  sv_region 0
  sv_gametypes "coop, versus, survival, scavenge"
  sv_allow_lobby_connect_only 0

===== Private server =====
By default, the server will be open to all comers.  The "sv_allow_lobby_connect_only 0" in the server config above prevents this.  To allow YOU to use it, use the "mm_dedicated_force_servers" console command before hitting "go" in the game lobby.  This command supports IP addresses only (no hostnames).  Example:

  mm_dedicated_force_servers 100.102.104.106:27015

To avoid having to type this, you can add a key bind to your game to set it.  Edit "''steamapps\common\left 4 dead 2\left4dead2\cfg\config.cfg''" and add the line:
  bind "F12" "mm_dedicated_force_servers 100.102.104.106:27015"

Then, in game, just hit F12 any time to make the game use your server.

===== Addons =====

Script to update the addons list when new addons are introduced ("remake-addonlist.pl"):
<code=perl>
#!/usr/bin/perl

use strict;

my $addonlist = "left4dead2/left4dead2/addonlist.txt";
my $addondir  = "left4dead2/left4dead2/addons";

rename($addonlist,"$addonlist.old");
open FP, "> $addonlist" or die "$addonlist: $!\n";

print FP <<EOL;
"AddonList"
{
EOL

my $n=0;

print "Writing addon list...\n";
for (glob("$addondir/*.vpk")) {
        s#.*/##;
        print FP qq(  "$_" "1"\n);
        print "- $_\n";
        $n++;
}

print FP "}\n";
close FP;

print "Wrote $n addons.\n";
