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. + </para> + <para> + For this module to function correctly there must be a correctly + formatted <filename>/etc/security/time.conf</filename> file present. + White spaces are ignored and lines maybe extended with '\' (escaped + newlines). Text following a '#' is ignored to the end of the line. + </para> + + <para> + The syntax of the lines is as follows: + </para> + + <para> + <replaceable>services</replaceable>;<replaceable>ttys</replaceable>;<replaceable>users</replaceable>;<replaceable>times</replaceable> + </para> + <para> + In words, each rule occupies a line, terminated with a newline + or the beginning of a comment; a '<emphasis remap='B'>#</emphasis>'. + It contains four fields separated with semicolons, + '<emphasis remap='B'>;</emphasis>'. + </para> + + <para> + The first field, the <replaceable>services</replaceable> field, + is a logic list of PAM service names that the rule applies to. + </para> + + <para> + The second field, the <replaceable>tty</replaceable> + field, is a logic list of terminal names that this rule applies to. + </para> + + <para> + The third field, the <replaceable>users</replaceable> + field, is a logic list of users or a netgroup of users to whom this + rule applies. + </para> + + <para> + A logic list namely means individual tokens that are optionally prefixed + with '!' (logical not) and separated with '&' (logical and) and '|' + (logical or). + </para> + + <para> + For these items the simple wildcard '*' may be used only once. + With netgroups no wildcards or logic operators are allowed. + </para> + + <para> + The <replaceable>times</replaceable> 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. + </para> + <para> + 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). + </para> + + <para> + For a rule to be active, ALL of service+ttys+users must be satisfied + by the applying process. + </para> + <para> + Note, currently there is no daemon enforcing the end of a session. + This needs to be remedied. + </para> + <para> + Poorly formatted rules are logged as errors using + <citerefentry><refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum></citerefentry>. + </para> + </refsect1> + + <refsect1 id="time.conf-examples"> + <title>EXAMPLES</title> + <para> + These are some example lines which might be specified in + <filename>/etc/security/time.conf</filename>. + </para> + <para> + All users except for <emphasis>root</emphasis> are denied access + to console-login at all times: + <programlisting> +login ; tty* & !ttyp* ; !root ; !Al0000-2400 + </programlisting> + </para> + + <para> + Games (configured to use PAM) are only to be accessed out of + working hours.
