Natural Selection 2 (NS2) is a fantastic game but there aren't enough UK servers, so the limited ones that are available are always full. Here is how you can host your own server.
- A box running Ubuntu 14.04
- 2 GB RAM (preferably more)
- 2 vCPUs (hyperthreading counts)
- CPU threads should be running 3Ghz+ as a rough measurement.
For this tutorial, I am going to be using a 2.5 GB VPS on my AMD FX 8320 server, with access to 2 vCPUs. The rest of the virtual machines running on that box are just static websites so the CPU won't suffer from noisy neighbours. You could also do this in Virtualbox. However, using a cheap $5 VPS is not likely to meet the CPU requirements as those machines have their CPU massively oversold and their processors are aimed at performance-per-watt rather than pure grunt.

Congratulations, you've performed the installation.
If you are hosting this from home, you now need to set up port forwarding on your router to open 27015 and 27016 so that others can join your server when you start it. This varies from router to router, but when using pfSense 2.3, this can be found under Firewall > NAT.
Starting the Server
Now you need to actually start an NS2 server. Below is an example command that you can customize to your needs. The parameters are self-explanatory.
./server_linux32 \ -name \"NS2 Server\" \ -port 27015 \ -webadmin \ -webdomain "192.168.1.1" \ -webuser admin \ -webpassword password \ -webport 8080 \ -map ns2_summit \ -limit 24
webdomain is set to the private/internal IP of the server, and not your properties public IP. If you want your friends to join you, find out your public IP from icanhazip and tell your friends to connect to it by using the command
connect [public ip here] in the NS2 console, which is accessed by hitting the top left key on your keyboard below escape when in the menu screen or in-game.
You can now configure your own NS2 server. Now the hardest bit is to get enough people to join to kick it off as nobody wants to join an empty server. If I can just figure out how to enable bots...
