DDmm expects to be invoked - with the name of a game that a user wishes to play. This is done by cre- - ating symbolic links to ddmm, in the directory /_u_s_r/_g_a_m_e_s for all of the - regulated games. The actual binaries for these games should be placed in - a ``hidden'' directory, /_u_s_r/_g_a_m_e_s/_h_i_d_e, that may only be accessed by the - ddmm program. DDmm determines if the requested game is available and, if so, - runs it. The file /_e_t_c/_d_m._c_o_n_f controls the conditions under which games - may be run. - - The file /_e_t_c/_n_o_g_a_m_e_s 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. - -FFIILLEESS - /etc/dm.conf configuration file - /etc/nogames turns off game playing - /usr/games/hide directory of ``real'' binaries - /var/log/games.log game logging file - -SSEEEE AALLSSOO - dm.conf(5) - -BBUUGGSS - Two problems result from ddmm running the games setuid ``games''. First, - all games that allow users to run UNIX commands should carefully set both - the real and effective user id's immediately before executing those com- - mands. Probably more important is that ddmm never be setuid anything but - ``games'' so that compromising a game will result only in the user's - ability to play games at will. Secondly, games which previously had no - reason to run setuid and which accessed user files may have to be modi- - fied. - -HHIISSTTOORRYY - The ddmm command appeared in 4.3BSD-Tahoe. - -BSD Experimental July 23, 1991 2 - - - - - - - - - - - - - - - - - - - - - |
