The King Arthur's Gold Server is a relatively lightweight, 32-bit command line application. Freely distributed, this program allows anybody with an internet connection and a computer to host their own King Arthur's Gold server.

Note: There is very little official documentation for the KAG server. As a result, the majority of this document was created from observation, trial and error. Use at your own risk.

Features

All servers are added to the official server list to be seen by anybody who chooses the "Pick a Server" option in-game.
Servers can be remotely controlled in game by anybody with the server's Remote Control (RCON) password.
Servers can be password protected. (This is separate from the RCON password.)

Requirements

Hardware

The hardware requirements for a KAG server are minimal. If a computer can run the full KAG game, it can run the KAG server.

Software

The KAG server can run on Linux, Windows, or Mac. The recommended operating system is Linux, specifically Debian.

Network

The KAG server isn't designed to work on computers without an Internet connection. It is, however, still possible to run it without one.

The KAG server uses three ports:

	Description	Modifiable?	Firewall Tolerant?
50301	Used to listen for connections.	yes	no
50328	Used to communicate with clients.	yes	yes
51308	Used to communicate with the master server.	no	yes

Firewall tolerant means that a typical connection-oriented (SPI) firewall will allow that port through. Depending on the firewall, all ports may need to be forwarded.

The internet connection is typically the bottleneck that determines the number of users a server can support. Hosting more users than a connection can support will cause a high ping time and significant lag.

Hosting on Residential Connections

For those hosting on residential internet connections, keep in mind that many ISPs forbid running any kind of server, including a KAG server. To complicate hosting a server, they may block certain ports and dynamically assign IP addresses.

It is highly unlikely that they would block the ports used by the KAG server. (A local router's firewall is most likely the culprit for connectivity issues when hosting on a residential connection.)
This site displays the IP address of the current visitor. It can be used to determine the currently assigned public IP address.

Installation

Linux

This guide is written for 32-bit Debian Linux. To run on 64-bit Debian Linux, the ia32-libs package must be installed.

First, download the server:

wget http://kag2d.com/en/download/kag_linux.tar.gz

Next, decompress the archive.
```
tar -zxf kag_linux.tar.gz
```
Change to the new directory:
```
cd kag_linux
```
Configure your server.
Run your server:
```
./KAGdedi
```
To connect, either find it in the server list or connect directly using the IPaddress:PortNumber format. (The default port is 50301.) Note that domain names will not work in place of the IP address.

Windows

First, download the server: http://kag2d.com/en/download
Note: The downloads page only lists a linux server. Even though the server is intended to run on Linux, it will run on Windows.
Next, decompress the archive. This can be done with many different programs, including PeaZip.
Open the folder the archive was extracted into.
Configure your server.
Run your server by clicking dedicatedserver.bat.
To connect, either find it in the server list or connect directly using the IPaddress:PortNumber format. (The default port is 50301.) Domain names will not work in place of the IP address.

Mac

Due to their similarities, the installation instructions for Linux should apply for Macs.

Configuration

The KAG server is configured using text files. Customizing a KAG server installation involves modifying the variables in these files. There are two ways to do this: manually and using Maqq's Configuration Tool. Of the two, Maqq's Tool is by far the fastest and easiest method.

One of the most important decisions a server administrator must make is whether or not to allow the Royal Guard to police their server. Please read the opening posts in these threads (In-game moderators (AKA Royal Guard) & The Royal Guard - FAQ & Public Policy) so you can make an informed decision.

If you decide you don't want guards to moderate on your server, please ensure they are turned off in your dedicated_autoconfig.gm file like this:

global sv_allow_globals_mods = 0;

Manual Configuration

Of the many editable configuration files that the KAG server depends upon, most customization is done in the dedicated_autoconfig.gm, dedicated_autostart.gm, mapcycle.cfg, and *-generator.cfg files. These are all in the kagServer/Base/Scripts directory, where kagServer is the directory the server was extracted into.

dedicated_autoconfig.gm

Of the many modifiable variables, these are some of the most important:

global m_width = 600; // Map generator width. Affects RAM usage.
global m_height = 250; // Map generator height. Affects RAM usage.
global m_seed = 0; // Map generator seed. Pick a random number.
global g_kickvote_percent = 33; // Percentage of players needed for a kick vote to pass.
global g_mapvote_percent = 51; // Percentage of team players needed for a map vote to pass.
global g_vote_time = 60; // How long (in seconds) does the voting take place.
global g_kickvote_bantime = 30; // How long (in minutes) is the player banned after a kick vote.
global sv_maxplayers = 16; // Maximum number of players allowed ingame.
global sv_port = 50301; // Server communication port, this is where it listens for incoming clients. Remember to open this port in your firewall.
global sv_password = ``; // Sets the server password.
global sv_rconpassword = ``; // Sets the server remote console password. This is important if you want to have control over your server.
global sv_require_auth = 1; // If set to 1 server checks client authentication via master server.
global sv_gold_only = 0; // If set to 1 only premium account players can join (aka Gold Server).
global sv_allow_globals_mods = 1; // If set to 1 global KAG moderators and admins can kick/ban players on server.
global sv_deltapos_modifier = 1; // Controls the threshold for delta packet updating. Value higher than 1 will reduce bandwidth, lower increase.
global sv_maxping = 450; // Max ping allowed on server after which player is kicked. Large ping players will slow down server.
global sv_maxping_warnings = 200; // Because of ping spikes, warnings are issued if a player has ping over max number.
global sv_maxhack_warnings = 25; // Maximum amount of warnings where server thinks player is hacking.
global sv_alloweditor = 1; // If set to 1 players that have RCON can start map editor on server
global sv_name = `KAG game`; // Sets the server name displayed in server browser.
global sv_info = ``; // Sets the server info displayed in server browser. If you want it multi-line simply move text to new line with enter.

dedicated_autostart.gm

// autostart on dedicated server launch


//set autostartswitch to:
//	0 for CTF 
//	1 for TDM
//	2 for Sandbox
//	3 for Zombies
//	4 for RTDM
//  10 for TEST

global autostartswitch = 0;

newWorld( "" );
switchGameState(0);

startServer();	

if (autostartswitch == 0) //ctf
{
	LoadRules("Rules/CTF/gamemode.cfg");
	LoadMapCycle( "Scripts/mapcycle.cfg" );
	LoadMap( "" );
	print(`Loaded CTF default config`);
}
else if (autostartswitch == 1) //tdm
{
	LoadRules("Rules/TDM/gamemode.cfg");
	LoadMapCycle( "Scripts/mapcycle.cfg" );
	LoadMap( "" );
	print(`Loaded TDM default config`);
}
else if (autostartswitch == 2) //sandbox
{
	LoadRules("Rules/Sandbox/gamemode.cfg");
	LoadMapCycle( "Scripts/mapcycle.cfg" );
	LoadMap( "" );
	print(`Loaded TDM default config`);
}
else if (autostartswitch == 3) //zombies (GOLD ONLY)
{
	LoadRules("Rules/Zombie_Survival/gamemode.cfg");
	LoadMapCycle( "Rules/Zombie_Survival/ZombieMapCycle.cfg" );
	LoadMap( "" );
	
	print(`Loaded zombies default config : server now in GOLD MODE`);
} else if (autostartswitch == 4) //rtdm
{
	LoadRules("Rules/RTDM/gamemode.cfg");
	LoadMapCycle( "Rules/RTDM/RTDMMapCycle.cfg" );
	LoadMap( "" );
	print(`Loaded RTDM default config`);
}else
if (autostartswitch == 10) //test
{
	LoadRules("Rules/TEST/gamemode.cfg");
	LoadMapCycle( "Scripts/mapcycle.cfg" );
	LoadMap( "" );
	print(`Loaded TEST default config`);
}

print(`Config finished loading from Scripts/Server/dedicated_autostart.gm`);

This file is very important. If you want to change rules for your server then you have to edit the global autostartswitch variable.

For an individual Rule there is the the number 10. If you want to make a Zombie Survival Server or any modded Server you need to make your server for Gold users only ( see dedicated_autoconfig.gm)

mapcycle.cfg

#KAG mapcycle;
# put map generator files, png files here, or script files
# eg. mapcycle = Maps/example1.png; Maps/example2.png; Maps/generator_flat.cfg; Maps/swordfight.gm;

mapcycle = Maps/generator_ctf_mountain.cfg;

You must separate paths to files with semicolons. Allowed files are generators, script files and maps in png format.

*-generator.cfg

Generators use "libnoise"-library.

Maqq's Server Configuration Tool

Maqq's command-line interface server configuration tool provides an interactive way of setting up a server:

Download in the root KAG directory (C:\KAG or /kag_linux , in windows and linux respectively).

In Windows, run KAGServer.exe and follow the onscreen instructions.
In linux, make it executable via chmod +x sconfig.py and run with ./sconfig.py . Daemonisation tools applicable to dedicatedserver.sh (screen, tmux, nohup etc) still useable with this program

Reusing Generated Configs

These commands reuse the generated configuration files:[1]

If you're using linux, type this in the console:

./KAGdedi autostart Scripts/custom_autostart.gm autoconfig Scripts/custom_autoconfig.gm

If you're using windows, you should consider using the [GUI version], it lets you save the configuration into a file, but if you want to use the CLI version, type this in the command prompt:

KAG autostart Scripts/custom_autostart.gm autoconfig Scripts/custom_autoconfig.gm

Download Maqq's Server Config Tool

Windows (GUI): http://dl.dropbox.com/u/51067730/kag/KAGServer.exe
Windows (CLI): http://dl.dropbox.com/u/51067730/KAGServer.exe (has python included)
Linux/OSX (CLI-only): http://213.152.176.254/mirror/sconfig.py

Remote Control

A server can be controlled in-game. While connected to the server, press the HOME key to open the console. Typing "/rcon password", where password is the RCON password set by sv_rconpassword, will allow the current user to send commands to the server. These commands must be prefixed by "/rcon". For example, to use the /list command, type. "/rcon /list".

Remote Server Commands

\list - list all commands and variables
\kick [playername] [minutes]
\kickid [id] [minutes]
\kickhost [host] [minutes] - kicks and/or bans host (host number can be found in logs when player joins)
\unbanhost [host] \unban; \unbanhost; \unbanhid commands
\swapid [player id] - swaps the players team
\players
\restartmap
\loadmap [name]
\savemap [name]
\msg [text]
\rcon [password]
addBotX - addBotX( team, class, name ); eg. addBotX( 1, 0, `St. John` );

Blacklisting & Whitelisting

A player blacklists is the list of players who are not allowed to play on a given server. A whitelist is the inverse of a blacklist; if enabled, only those on the whitelist will be allowed to play.

How to Create a Blacklist or Whitelist

Create the following file and save it as securitysetup.cfg in kagServer/Base/Scripts, where kagServer is the path to the kagServer's directory.

# security setup
# set this to 1 to allow only the names in whitelist

	whitelist_active = 0;
	whitelist =  names; go; here; 

#blacklist format: name; IP; expiration time and date h:m:s:d:M:y; reason;
#	IP of 0 means no IP is banned, and the user is just banned by username.
#		Username of 0.0.0.0 means no IP is banned for that entry
#	The time is in C++ struct tm format except for the year, which is human readable.
#		eg: 10:30:0:31:11:2050 is 10:30 AM on the 31st of December 2050AD

	blacklist = name1; 0.0.0.0; 10:30:0:31:11:2050; Banned; 
		name2; 12.34.45.78; 10:30:0:31:11:2050; Banned;

Note: The whitelist overrides the blacklist.

Managing Instability

As Alpha software frequently is, the KAG server is very unstable. Recent builds have been especially prone to crashing whenever left running for more than 24 hours. As such, it is recommended practice run the server in a keepalive script, which will restart it whenever it crashes. (In addition, many people restart their server once a day, during the hours of least usage, to help decrease the risk of a crash while the server is being played upon.)

Trelawney's Keepalive Script for Linux

This script, dedi.sh, will restart the KAG server 5 seconds after it crashes. Download it here.
If retyping/using copy and paste, make sure word wrapping is turned off in you text editor. (In nano, use nano -w dedi.sh .)
Once created, be sure to make the script executable with chmod +x dedi.sh.

#!/bin/bash
echo "Running KAG dedicated server"
echo "TO SET IP/PORT/SLOTS/PASSWORD ADD THESE COMMAND PARAMS: ip 127.0.0.1 port 50213 slots 32 password pass123"
mv KAGdedi.tmp KAGdedi
chmod +x KAGdedi
until ./KAGdedi nolauncher autostart Scripts/dedicated_autostart.gm autoconfig Scripts/dedicated_autoconfig.gm; do
        echo "KAG server running"
        sleep 5
done

To use, run the script: ./dedi.sh

Adapting for Maqq's Configuration Tool

To use a configuration generated by Maqq's Configuration Tool, replace line 6 in the above script with:

./KAGdedi autostart Scripts/custom_autostart.gm autoconfig Scripts/custom_autoconfig.gm

The Beaz's Keepalive Script for Windows

This script, dedi.bat, will restart the KAG server 5 seconds after it crashes. To use, create a text file, paste/type in the script below, and save it as dedi.bat.

@ECHO off
 
:restart
echo (%time%) Server Started - close this window to prevent restart.
 
start /wait KAG.exe nolauncher autostart Scripts/dedicated_autostart.gm autoconfig Scripts/dedicated_autoconfig.gm
 
echo (%time%) WARNING: Server closed or crashed, restarting.
 
goto restart

Adapting for Maqq's Configuration Tool

To use a configuration generated by Maqq's Configuration Tool, replace line 6 in the above script with:

start /wait KAG.exe nolauncher autostart Scripts/custom_autostart.gm autoconfig Scripts/custom_autoconfig.gm

Daily Server Restarts

If a KAG server is running in a keepalive script, a scheduled task/cronjob that kills the server once a day is, effectively, a daily restart because the keepalive script will automatically restart the server.

For Linux - Cronjob

This script will kill all instances of KAGdedi at 3 AM.

Use crontab -e to create a new cronjob. This will open your default text editor.
In the text editor, type:
```
0 3 * * * pkill -1 KAGdedi
```
Close editor. Cronjob installed!
