How to server

From QWiki

This page describes how to setup a QuakeWorld server.

The easiest way of running a server is installing nQuakesv package. Get it here.

It includes everything you need to start a server, including:

It is preconfigured, just asks the user simple questions to complete the configuration. Take note on the ports the servers will be running (you must know them to connect to the servers)

Choosing a provider

Game servers can run on any computer that is connected to a network. To host a game server on the internet, renting a VPS in a Datacenter is the most common, effective and cheapest way.
There are VPS offerings in most of the countries in the world. Choosing one with good routing that is good can be a daunting task. Below are some facts and tips for choosing a VPS provider.

  • Rule of thumb: the higher the distance between the server and the client, the higher the ping.
  • Routing is important: the player's ISP AND the VPS Datacenter determine the route that the game packets (information) have to travel to reach the destination. This directly affects the ping. Also, as a rule of thumb, the less hops, the better ping.
  • The ping will be the same regardless of its direction. Host A ping to Host B is the same from Host B to Host A.
  • Well located servers using good routes enable us to play with sub 100ms ping between continents. But nothing can beat the speed of light - distance is key. Routes using submarine cables (when possible) are often better than routes that go through datacenters on land, because of the number of hops.
  • How to test the ping? Some VPS providers have a Looking glass you can use to test latency. Looking Glass is an open source publicly available networking script to check the Host, Ping, Traceroute, MTR, Speed, and Latency of the VPS or Server and Network. Here are some examples:
  • You can test your own ping to a VPS, or test any other ip ping to that VPS. Examples:
    • Test your own ping to the VPS network by placing your own ip in the "ping" textbox.
    • Test some existing QW server ping to the VPS network. This is useful to test if the VPS can be useful for QWfwd proxies. This is how different players can get the best possible ping to a destination server.
    • Test the ping to other VPS (looking glass). The Looking glass also has a test ip, which you can use to ping to. This is useful to check the connection between VPSs, for QWfwd proxies.

Server specifications

In terms of minimum server specifications, it depends on what you plan to run there. But a single core cpu and 1gb of RAM is enough to run a couple of KTX ports, QWfwd and QTV. No need to overpay.

Server maintenance

Antilag

As of 2024, there are updates to antilag feature that have not been merged in the main repositories. If you want to set qw servers with the latest antilag, you got to compile them yourself.

Ciscon has prepared scripts to compile the binaries for KTX and MVDSV. These scripts are included in nQuakesv, but you can also find them here (the nQuake ones).
All you have to do is edit the scripts:

  • MVDSV script: replace in gitrepo qw-group with dusty-qw
  • KTX script: replace in gitrepo qw-group with dusty-qw
  • KTX script: replace in gitbranch master with al-merge-2

And run them. If they run successfully, the server is ready to go with the updated binaries.
Here's the list of dependencies to run them (linux Debian): # apt-get install git qstat make gcc pkg-config cmake curl unzip -y
Here are the links to the Antilag repositories in Github: mvdsv antilag and ktx antilag

Updating server binaries

If you are lazy, the latest precompiled server binaries are here: https://builds.quakeworld.nu/
See Antilag section above.

Updating maps

If using Linux nQuakesv, please run ./update_maps.sh to get the latest maps on your server.

Uploading individual maps

Map files (.bsp files) go into /qw/maps folder. A way to do it fast is the following:

  1. Download file locally
  2. Open terminal (in windows or mac or linux) and use scp to copy the file to the remote location:
scp <file.bsp> <username>@<server>:~/nquakesv/qw/maps

SCP also allows to use SSH keys (-i <path to key file>) and defining a custom port (-P <portno>).
Alternatively, you can use pscp (Putty scp), as it is better adapted to Windows OS.
Example with private key and custom port:

pscp -i "C:\priv.ppk" -P 26789 faust.bsp myusername@myserver.org:/quakeantilag/qw/maps

You can create a script for your servers for doing it faster.

Updating server configs

If using Linux nQuakesv, use the built-in scripts to do so: 

./update_binaries.sh
./update_configs.sh

Advanced

KTX Server Setup

If for some reason you need to upgrade KTX, you'll have to compile it. here's how to do it (using QW-Group's github) 

1. git clone https://github.com/QW-Group/ktx
2. cd ktx
3. cmake .
4. make -j$(nproc)
5. ls -altr (look for qwprogs.so)
6. copy qwprogs.so to ktx/ folder
7. restart the server

When restarting the server, if it outputs a message about failing to load qwprogs.so you'll have to recompile mvdsv also.
If you haven't done it already, you should edit pwd.cfg and change the rcon password. You should also edit portX.cfg and change the sv_serverip to the external (WAN) ip:port of the machine.

MVDSV Setup

Compiling MVDSV (using QW-Group's github): 

1. git clone https://github.com/QW-Group/mvdsv
2. cd mvdsv/build/make/
3. cmake .
4. make -j$(nproc)
5. chmod 755 mvdsv
6. copy mvdsv to your quake/ folder

Then run it. it has several command line parameters, such as -port (to choose port) -game (to choose folder) and +exec (to automatically run a cfg and +set sv_getrealip ). Example mvdsv execution commands: 

./mvdsv -port 27502 -game ctf +set sv_getrealip 1
./mvdsv -port 27500 -game prox +exec qw_server.cfg
./mvdsv -port 27501 -game ktx +exec port1.cfg

Firewall Configuration

iptables -A PREROUTING -t nat -p udp -i eth1 --dport 27500 -j DNAT --to 192.168.0.1:27500

Raspberry Pi server

Raspberry Pi (arm/arm64) binaries for qwfwd, mvdsv, and ktx binaries are available from https://builds.quakeworld.nu
Spike also compiled binaries for FTE, both client and server. Download them from here

Test results on a raspberry 1, 512mb ram:
- with 7 players + 1 spec, cpu usage was around 80% with everyone spamming sng at dm3 outside
- in conclusion it will be enough for 2on2, not sure on a competitive 4on4 match.
- raspberry pi 2 should be enough for 4on4
