[edit] Server Requirements

The King Arthur's Gold Beta 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.

[edit] Residential Connections

For those hosting on residential internet connections:

  • Make sure that your computer has at least the above specifications.
  • Keep in mind that many ISPs forbid running any kind of server, including a KAG server, they may block certain ports and dynamically assign IP addresses.

[edit] Dedicated Servers

[edit] Software

  • The KAG server can run on almost all OS.
  • To run a KAG server on Linux you must have the latest version of your distro but Debian 6 is supported too (maybe more, to be tested).
  • The recommended operating system is Linux, specifically Ubuntu or Debian.

[edit] Lowest Hardware

  • RAM: At least 128MB
  • CPU: At least 1 core clocked @ 1Ghz

[edit] Recommended Hardware

  • RAM: 512MB
  • CPU: 1 cores clocked @ 2Ghz

[edit] Network

  • Internet Connection speed per player scales with the number of players:
  • Upload to each player: (number of players - 1) * 0.3 kb/s
  • Download from each player: 0.5kb/s

[edit] Ports

  • 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 in UDP.
Description Modifiable? Firewall Tolerant?
50301/udp Used to listen for game connections. yes no
50301/tcp Used to listen for remote admin (tcp rcon) connections. yes no
50328/udp Used to communicate with clients. yes yes
80/tcp Used for autoupdates no yes
443/tcp Used for API (server list, auth, minimaps, etc) server communication no yes

[edit] Installation

[edit] Linux Install

[edit] Basic Install

This guide is written for Debian based distributions.
If your OS is 64-bit start here.
For OS that support multiarch (For Ubuntu it's 12.04 or newer):

  1. Check your foreign architectures:
    sudo dpkg --print-foreign-architectures
  2. If i386 is not present:
    sudo dpkg --add-architecture i386
  3. Update your package list:
    sudo apt-get update
  4. Install 32-bit libraries required for KAG:
    sudo apt-get install libc6:i386 libstdc++6:i386 libglapi-mesa:i386 libgl1-mesa-glx:i386 libxxf86vm1:i386 libxext6:i386 libx11-6:i386 libfreetype6:i386 libgcc1-dbg:i386 libxdamage1:i386 libxfixes3:i386 libx11-xcb1:i386 libxcb-glx0:i386 libxcb-dri2-0:i386 libxcb1:i386  libdrm2:i386 libxdmcp6:i386
For OS that do not support multiarch:
  1. Install 32-bit Libraries:
    sudo apt-get install ia32-libs
If your OS is 32-bit start here.
  1. Download the server:
    wget http://dl.kag2d.com/kagbeta-linux32-dedicated.tar.gz
  2. Next, decompress the archive:
    tar -zxf kagbeta-linux32-dedicated.tar.gz
  3. Change to the new directory:
    cd kagbeta-linux32-dedicated
  4. Allow the server to be executed:
    chmod +x KAGdedi

  5. Run your server:
    ./KAGdedi

[edit] Using Screen

It is recommend to use Screen while hosting (multiple) servers (on a Virtual Server). Basically what screen is can be found here. In simple words screen is a program which lets you create multiple terminal sessions. For example, if you don't want to run all the processes on your main terminal you can easily create a 'screen' and run your server there. After you installed like stated above, stop before ./KAGdedi. This is where you don't run KAG but start the 'screen' and run it there.

  1. First, download screen if you haven't got it:
     sudo apt-get install screen
  2. Now, in you KAG server folder create a new screen:
    screen -S MyScreenName

Note that the -S is a capital s and not a small one (s)!
  1. Now, start your server:
    ./KAGdedi

Some basic screen instructions:
  1. To open a screen, for example when you shut down your terminal and you want to restart your server:
    screen -x MyScreenName

  2. Want to stop your server: Press "ctrl+c" (general Linux command to kill a process).
  3. Want to kill the screen as you don't use/need it anymore, do this in your screen: ctrl+a+k and press Y to confirm.
  4. Want to go out of a screen/detach, do this (in your screen, of course): ctrl+a+d.

[edit] Windows Install

  1. First, download windows KAG at: http://kag2d.com/en/download
  2. Install
  3. Run your server by executing dedicatedserver.bat.

[edit] Port Forwarding

[edit] Router

As said before KAG Servers require various ports to be open for it to run properly. If you are using a router, it most likely has its own firewall. Unfortunately since there are many router manufacturers, its almost impossible for a universal guide that would offer step-by-step instructions on how to set up these 'port forwards'. Please consult your router manufacturer's website for more precise information on how to accomplish this.

[edit] Windows Firewall

If you are running a Windows OS this is most likely active on your computer blocking certain ports . The following steps were done on a Windows 7 computer but other Windows OS should be nearly identical.

  1. Go to Control Panel and open the Security and Security tab.
  2. Click on "Windows Firewall".
  3. Click on "Advanced settings" on the left hand side column.
  4. Right click on the "Inbound Rules" button, in the left hand side column, and select "New Rule..."
  5. Select "Port" and click "Next".
  6. Type in the port you wish to allow (they are found above) and click "Next".
  7. Select "Allow this connection and click "Next"
  8. (Recommended) Select "Domain", "Private" and "Public"
  9. Type in a Name and click "Finish.
  10. Repeat steps 4-9 for all the ports

[edit] Mac Firewall

  1. Download Portmap: http://www.macupdate.com/app/mac/27342/port-map/
  2. Next, decompress the archive. This can be done with many different programs, including PeaZip.
  3. Launch Portmap.
  4. Open the required ports.

[edit] Antivirus Firewall

Like Windows Firewall, if you have an antivirus it most always has a firewall. Unfortunately since there are many antivirus products on the market, its almost impossible for a universal guide that would offer step-by-step instructions on how to set up these 'port forwards'. Please consult your antivirus brand's website for more precise information on how to accomplish this.

[edit] Configuration

The KAG server is configured using text files. Customizing a KAG server installation involves modifying the variables in these files. Most of the key variables, such as player amount, ports used to connect, IP or weather or not guards (see below) can moderate the server are found in the autoconfig.cfg file, stored in KAGServ/autoconfig.cfg

[edit] autoconfig.cfg

Key variables in autoconfig.cfg


sv_gamemode = TDM                                                        # The gamemode launched on start of dedicated server. This is the DIRECTORY name under Base/Rules!

                                                                           game traffic (currently). Set to 0 for automatic detection.

sv_register = 1                                                          # Whether or not to register this server with the master list.  You likely only want this set to 0 if this is a firewalled private server.

sv_preferAF = 0                                                          # Server AF preference for whether clients connect using IPv4 or IPv6. Set to 0 for clients to use whichever performs better when both are available

sv_enableIPv6 = 1                                                        # Whether to use IPv6 globally. Set to 0 to disable IPv6 globally including for API calls (NOT RECOMMENDED!).

sv_port = 50301                                                          # Server communication port, this is where it listens for incoming clients. Remember to open this port in your firewall.

cl_port = 50328                                                          # Client communication port.

sv_password =                                                            # Sets the server password.

sv_rconpassword =                                                        # Sets the server remote console password.

disable_seclevoutput = 1                                                 # If set to 1 then loading seclevs will not print them out.

sv_allow_globals_mods = 1                                                # If set to 1 global KAG moderators and admins can kick/ban players on server.

sv_compression = 1                                                       # Compress network data or not. Disabling compression may improve performance. DO NOT change this while running the server!

sv_maxping = 450                                                         # Max ping allowed on server after which player is kicked. Large ping players will slow down server.

sv_maxping_warnings = 600                                                # Because of ping spikes, warnings are issued if a player has ping over max number.

sv_maxhack_warnings = 25                                                 # Maximum amount of warnings where server thinks player is hacking.

sv_name = KAG Server                                                     # Sets the server name displayed in server browser.

sv_info =                                                                # Sets the server info displayed in server browser.

sv_global_bans = 0                                                       # Determines whether the server uses the KAG accounts global ban data.

u_shownames = 0                                                          # Show team member names above head


[edit] Setting the Server name and description

Setting a name for your server is easy, simply open up KAGServ/autoconfig.cfg and you will find the variables; sv_name and sv_info; to set the name simply enter your desired name after sv_name = %the_name_of_your_server% and for the description (the information in the side panel when selecting a server in game) edit sv_info = %Your_server_description_here%

[edit] Enabling or disabling Global moderation AKA; "Royal Guards"

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 autoconfig.cfg and in your security levels.

The variable used to allow/disallow guards is:

sv_allow_globals_mods = 1                                                # If set to 1 global KAG moderators and admins can kick/ban players on server.

[edit] Setting the server gametype

The variable to set the server gametype is found inside autconfig.cfg

sv_gamemode = TDM                                                        # The gamemode launched on start of dedicated server. This is the DIRECTORY name under Base/Rules!

The variable is the name of the location of of a gamemode file; usually stored in KAGServ/Base/Rules but can be pointed elsewhere, such as ../Mods/my_game_type/. In the example above, we are pointing to KAGserv/Base/Rules/TDM/ so that we load the Team Death Match game type.


[edit] Setting a mapcycle

A mapcycle is essentially a list of maps that your server will put on rotation; you can point to your mapcycle.cfg file using this variable inside your autoconfig.cfg

sv_mapcycle =  Base/Maps/mapcycle.cfg                                                          # The default map cycle loaded on server start...

Example mapcycle.cfg:

# KAG mapcycle;
# used when defined in variable sv_mapcycle - see autoconfig.cfg for details
# loads .PNG, .KAG and .AS files

mapcycle = Maps/WARDraft.png; Maps/Custom.kag; ../Mods/My/mymap_script.as

In this example, every line that beings with # denotes a comment, or a line that will not be read by KAG. Each map is separated by a semi colon ';'. If this option is not set in autoconfig.cfg, then KAG will simply load the ones as part of the rules of the gametype you have chosen to run on your server.

[edit] Day/Night Cycle in gamemodes other than Take the Halls

To enable day and night, simply open up the gamemode.cfg file, located Kagserv/Base/Rules/%your_game_mode_choice%/ and change the variables:

daycycle_speed                     = 0                  # 1 day = X minutes; / 0 no cycle
daycycle_start                     = 0.5        # 0.0 midnight; 0.5 - midday; 1.0 midnight

[edit] Remote Control

<p>A server can be controlled in-game. While connected to the server, press the HOME key to open the console. A full list of available rcon commands can be found here. In order to remote control a server however you must be set as an administrator in the servers configuration files. The system KAG uses for this is found bellow.

You are also able to remotely control your server when you've set sv_tcpr to 1. More info at Remote Administration

[edit] Security Levels

King Arthur's Gold uses a system called 'Security Levels' (or 'seclevs' for short) to manage player access to various features on its servers. There are default, hardcoded levels setup but it is strongly advised that server owners take the time to setup their own specific seclev definitions.

[edit] 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.

The security contents of the file autoconfig.cfg should look something like this:

security_whitelist_active = 0  # Set to 1 to allow only the names in the whitelist or 0 to disallow the names in the blacklist
security_whitelist = ../Security/whitelist.cfg # The file with the whitelist config
security_blacklist = ../Security/blacklist.cfg # The file with the blacklist config
security_ignorelist = ../Security/ignorelist.cfg # The file with the ignorelist config
security_seclevs = ../Security/seclevs.cfg # The file with the seclev config

Note: The whitelist overrides the blacklist if enabled.

[edit] Whitelist

If you are using the whitelist, then at the path specified in whitelist_file you can create a file that looks something like this:

# Whitelist format: name; anothername; yetanothername;
whitelist =
name;
anothername;
yetanothername;

Simply add usernames in this way to allow only those players access to the server.

[edit] Blacklist

If you are using the blacklist, then at the path specified in blacklist_file you can create a file that looks something like this:

# Blacklist format: name; IP; expiration time and date h:m:s:d:M:y; reason;
# IP of 0.0.0.0 means no IP is banned, and the user is just banned by username.
# Blank username means no user is banned for that entry and it's just by IP.
# The time is in C++ struct tm format except for the year, which is human readable. Get relative times from /listbans on the console.
#       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;

Simply add player details in the format described to ban them from the server. Alternatively, just use the ban menus or rcon commands in game to ban users. Note that January is the 0th month

[edit] Managing Instability

As Alpha software, the KAG server in certain builds is very unstable. Build are sometimes crash prone but it varies from release to release due to new features mixed with bug fixes. As such, it is recommended practice to 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.

[edit] Keep-alive Scripts

[edit] Linux/Mac

Trelawney's Keepalive 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/server_autostart.as autoconfig ../autoconfig.cfg; do
        echo "KAG server running"
        sleep 5
done

To use, run the script: ./dedi.sh instead of the usual ./KAGdedi

[edit] Windows

The Beaz's Keepalive 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/server_autostart.as autoconfig ../autoconfig.cfg
 
echo (%time%) WARNING: Server closed or crashed, restarting.
 
goto restart

To make it work on Windows Vista or 7 you need to disable Windows Error Reporting. To do so:

  • Run regedit.exe
  • Modify HKCU\Software\Microsoft\Windows\Windows Error Reporting\DontShowUI entry with value 1

[edit] Daily Server Restarts

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

[edit] Linux/Mac - Cronjob

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

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