Proof-of-concepts for the fake players bug that affects almost all the multiplayer games (and not only them).
Note that disabling the outgoing ICMP packets on the own system is suggested for testing the fake players bug (the Windows firewall already does this by default, so there is nothing to touch)

- Generic TCP Fake Players DoS 0.2.2a (tcpfp)
basic tool which creates multiple simultaneous connections to a specific host and port, something similar to a simple "for(;;) connect();" supports also some options for adapting it to specific types of servers through the sending of custom data (-f option).
it's interesting to notice that various programs which accept TCP connections suffer of some negative effects caused by their stressing through this simple tool.
- Unreal engine basic client and Fake Players DoS 0.2.8 (unrealfp)
interesting project about a basic client for sending custom commands to the servers of almost any game based on Unreal engine 1, 2 and 3:

- Brothers in Arms
- Deus Ex
- Frontline: Fuel of War
- Land of the dead
- Magic: The Gathering - Battlegrounds

- does not work with Klingon Honor Guard and probably other old games while others just crash completely due to their bugged netcode.
- depending by the version of the engine, it can test passworded servers without knowing the keyword.
- with the games based on the Unreal 3 engine and where is possible to use the JOINSPLIT command (Unreal Tournament 3, America's Army 3 and so on), it's enough to specify such command for testing the filling of the entire server slots using only one player: unrealfp -1 -x 2 -s JOINSPLIT 1 64 -l "ui_bink_master?Name=player?team=0?Face=0" 127.0.0.1 7777

this is a fake players proof-of-concept which works with any game that use DirectPlay 8.
that version of DirectPlay is used by various games (DirectX 8/9, the older use DirectPlay 7) which can be easily recognized by the dpnsvr.exe process and/or the UDP port 6073 in listening mode when the server is running.
it uses some files (called join_files) needed for each specific game because, except some of them, many games use some particulars parameters in the join packet which sometimes change even between different game versions.
read the text file inside for all the needed information, details and examples.
