I was playing these days with Teeworlds (ex Teewars), with both the client and the server software. So I found that the only problem the Ubuntu package has, is the lack of an init script for teewars-server in init.d.

Here’s an example of teeworlds-server init script. Once the installation package also has no predefined path for configuration file, I advice you first to read the values of the variables I used in the script, before installing it.

Happy playing! :)
