i made a pull request here https://github.com/xerxes-at/T6ServerConfigs/pull/5
that allowed me to run the server on linux.
WARNING: this only works on kernel version 4.18.X or below (or a patched and rebuilt wine, but building wine is a real pain), and the console window for the server is pretty much useless.
if you are running headless, take a look at the reply i made to the pull request., or the commented out line near the bottom.
also, cd to the directory before launching the server.
