What works

TWGS installs successfully into a fresh WINEPREFIX with no winetricks needed. One of the dialog windows during installation may appear misshapen. TWGS has also been tested with PlayOnLinux and found working well.

TWGS is started by running twgs.exe. By default, TWGS is configured to listen on port 23. This will result in an expected error message upon startup:

Error binding player listener (10013)

However, this would only succeed with root privilege (or equivalent), and so this is not alarming. The listening port and other server settings are mainly found via the menu path: Server -> Configure. From there, explore the four tabs.

TWGS works in general and can be used as expected, save for "Autorun" and "Run as service" type features which do not provide their original convenience under WINE.

Confirmed to work: Game initialization (called "Big Bang"), game import and export, external maintenance, gold aliens, alien manager, Tedit, administration via the admin port, gameplay via the standard port, logging, node snooping, extreme game parameters (30,000 sectors, 1000 NPC aliens) and long-term operation.

What does not

A problem exists where only 63 simultaneous connections will be supported, even if the server is licensed for more. The problem is described in Bug 50352 - Maximum sockets per process is set very low.

TWGS will detect on startup if the maximum number of sockets it will be allowed to open is too low. If it will hit that limit before a license limit, an error will be shown, but TWGS will still be usable for up to 63 simultaneous connections.


Regarding the limit of 63 simultaneous connections:

Workaround 1: Do nothing, as the limit is going to be very difficult to reach without connecting to TWGS about 63 times yourself.

Workaround 2: Rebuild WINE with WS_MAX_SOCKETS_PER_PROCESS > 202, per the bug.

What was not tested

After a couple years of operation, very little has been left untested.

Additional Comments

It's generally suggested to install to C:/EIS/TWGS/ instead of under "Program Files" as many 3rd party utilities (which also work under WINE) break when encountering spaces in paths.

A problem has been observed where a game's FERRENGI.DAT grows without bounds, potentially to the point of filling the disk. The game had Gold Aliens enabled, and thus Gold Ferrengi, which means the game does not actually utilize FERRENGI.DAT which belongs to internal Ferrengi only. Nonetheless, some combination of running under WINE and game parameters could cause this problem which causes TWGS to fill this file with zeros. Since the file is not used, symlink it to /dev/null:

FERRENGI.DAT -> /dev/null

The following files may help provide hints with running TradeWars in a server-like manner with the GUI in a VNC session.

The following systemd unit references the "vncserver" service, a part of tigervnc. A persistent Xvnc session begins as the user tw2002, configured by assigning display :2 to user tw2002 in /etc/tigervnc/vncserver.users, then enabling the corresponding vncserver@:2.service. This VNC session can then be connected to.
