NAME

     trek -- trekkie game

SYNOPSIS

     trek [-sf]

DESCRIPTION

     trek is a game of space glory and war.  Below is a summary of commands.  For complete documentation, see Trek by Eric Allman.

     The -s flag makes the game somewhat more efficient if you have a (very) slow terminal.  The -f flag (the default) is for faster terminals.

     The game will ask you what length game you would like.  Valid responses are ``short'', ``medium'', and ``long''.  You may also type
     ``restart'', which restarts a previously saved game.  You will then be prompted for the skill, to which you must respond ``novice'',
     ``fair'', ``good'', ``expert'', ``commodore'', or ``impossible''.	You should normally start out with a novice and work up.

     In general, throughout the game, if you forget what is appropriate the game will tell you what it expects if you just type in a question
     mark.

DM(8)							    BSD System Manager's Manual 						     DM(8)

NAME

     dm -- dungeon master

SYNOPSIS

     ln -s dm game

DESCRIPTION

     dm is a program used to regulate game playing.  dm expects to be invoked with the name of a game that a user wishes to play.  This is done by
     creating symbolic links to dm, in the directory /usr/games for all of the regulated games.  The actual binaries for these games should be
     placed in a ``hidden'' directory, /usr/lib/games/dm, that may only be accessed by the dm program.	dm determines if the requested game is
     available and, if so, runs it.  The file /etc/dm.conf controls the conditions under which games may be run.

     The file /etc/nogames may be used to ``turn off'' game playing.  If the file exists, no game playing is allowed; the contents of the file
     will be displayed to any user requesting a game.

FILES

     /etc/dm.conf	   configuration file
     /etc/nogames	   turns off game playing
     /usr/lib/games/dm	   directory of ``real'' binaries
     /var/games/games.log  game logging file

SEE ALSO

     dm.conf(5)

HISTORY

     The dm command appeared in 4.3BSD-Tahoe.

SECURITY CONSIDERATIONS

     Two issues result from dm running the games setgid ``games''.  First, all games that allow users to run UNIX commands should carefully set
     both the real and effective group ids immediately before executing those commands.  Probably more important is that dm never be setgid any-
     thing but ``games'' so that compromising a game will result only in the user's ability to play games at will.  Secondly, games which previ-
     ously had no reason to run setgid and which accessed user files may have to be modified.
