TIME.CONF(5)							 Linux-PAM Manual						      TIME.CONF(5)

NAME

       time.conf - configuration file for the pam_time module

DESCRIPTION

       The pam_time PAM module does not authenticate the user, but instead it restricts access to a system and or specific applications at various
       times of the day and on specific days or over various terminal lines. This module can be configured to deny access to (individual) users
       based on their name, the time of day, the day of week, the service they are applying for and their terminal from which they are making
       their request.

       For this module to function correctly there must be a correctly formatted /etc/security/time.conf file present. White spaces are ignored
       and lines maybe extended with '' (escaped newlines). Text following a '#' is ignored to the end of the line.

       The syntax of the lines is as follows:

       services;ttys;users;times

       In words, each rule occupies a line, terminated with a newline or the beginning of a comment; a '#'. It contains four fields separated with
       semicolons, ';'.

       The first field, the services field, is a logic list of PAM service names that the rule applies to.

       The second field, the tty field, is a logic list of terminal names that this rule applies to.

       The third field, the users field, is a logic list of users or a netgroup of users to whom this rule applies.

       For these items the simple wildcard '*' may be used only once. With netgroups no wildcards or logic operators are allowed.

       The times field is used to indicate the times at which this rule applies. The format here is a logic list of day/time-range entries. The
       days are specified by a sequence of two character entries, MoTuSa for example is Monday Tuesday and Saturday. Note that repeated days are
       unset MoMo = no day, and MoWk = all weekdays bar Monday. The two character combinations accepted are Mo Tu We Th Fr Sa Su Wk Wd Al, the
       last two being week-end days and all 7 days of the week respectively. As a final example, AlFr means all days except Friday.

       Each day/time-range can be prefixed with a '!' to indicate "anything but". The time-range part is two 24-hour times HHMM, separated by a
       hyphen, indicating the start and finish time (if the finish time is smaller than the start time it is deemed to apply on the following
       day).

       For a rule to be active, ALL of service+ttys+users must be satisfied by the applying process.

       Note, currently there is no daemon enforcing the end of a session. This needs to be remedied.

       Poorly formatted rules are logged as errors using syslog(3).

EXAMPLES

       These are some example lines which might be specified in /etc/security/time.conf.

       All users except for root are denied access to console-login at all times:

	   login ; tty* & !ttyp* ; !root ; !Al0000-2400

       Games (configured to use PAM) are only to be accessed out of working hours. This rule does not apply to the user waster:

	   games ; * ; !waster ; Wd0000-2400 | Wk1800-0800

NAME

     dm.conf -- dungeon master configuration file

DESCRIPTION

     The dm.conf file is the configuration file for the dm(8) program.	It consists of lines beginning with one of three keywords, badtty, game,
     and time.	All other lines are ignored.

     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 ttyname(3).	For example, to keep the uucp dialout, ``tty19'', from being used for games, the entry
     would be:

	   badtty  /dev/tty19

     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:

	   time    Monday  8	   17

     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 aver-
     age of 5 or less; all other games may be run any time the system has 15 or less users.

	   game    hack 	   5	   10	   *
	   game    default	   *	   15	   *
