|
||
|
|
The
|
||
|
|
.Xr dm.conf
|
||
|
|
file
|
||
|
|
is the configuration file for the
|
||
|
|
.Xr \&dm 8
|
||
|
|
program.
|
||
|
|
It consists of lines beginning with one of three keywords, ``badtty'',
|
||
|
|
``game'', and ``time''. All other lines are ignored.
|
||
|
|
.Pp
|
||
|
|
Any tty listed after the keyword ``badtty'' may not have games played on
|
||
|
|
it.
|
||
|
|
Entries consist of two white-space separated fields: the string
|
||
|
|
``badtty'' and the ttyname as returned by
|
||
|
|
.Xr ttyname 3 .
|
||
|
|
For example,
|
||
|
|
to keep the uucp dialout, ``tty19'', from being used for games, the
|
||
|
|
entry would be:
|
||
|
|
.Bd -literal -offset indent
|
||
|
|
badtty /dev/tty19
|
||
|
|
.Ed
|
||
|
|
.Pp
|
||
|
|
Any day/hour combination listed after the keyword ``time'' will disallow
|
||
|
|
games during those hours. Entries consist of four white-space separated
|
||
|
|
fields: the string ``time'', the unabbreviated day of the week and the
|
||
|
|
beginning and ending time of a period of the day when games may not be
|
||
|
|
played. The time fields are in a 0 based, 24-hour clock. For example,
|
||
|
|
the following entry allows games playing before 8AM and after 5PM on
|
||
|
|
Mondays.
|
||
|
|
.Bd -literal -offset indent
|
||
|
|
time Monday 8 17
|
||
|
|
.Ed
|
||
|
|
.Pp
|
||
|
|
Any game listed after the keyword ``game'' will set parameters for a specific
|
||
|
|
game. Entries consist of five white-space separated fields: the keyword
|
||
|
|
``game'', the name of a game, the highest system load average at which the
|
||
|
|
game may be played, the maximum users allowed if the game is to be played,
|
||
|
|
and the priority at which the game is to be run. Any of these fields may
|
||
|
|
start with a non-numeric character, resulting in no game limitation or
|
||
|
|
priority based on that field. The game "default" controls the settings for
|
||
|
|
any game not otherwise listed, and must be the last ``game'' entry in the
|
||
|
|
file. Priorities may not be negative. For example, the following entries
|
||
|
|
limits the game ``hack'' to running only when the system has 10 or less
|
||
|
|
users and a load average of 5 or less; all other games may be run any time
|
||
|
|
the system has 15 or less users.
