|
|
.PP

|
|
|
Each entry consists of three colon separated fields.
|
|
|
|
|
The first field is a comma separated list of tty devices,
|
|
|
|
|
or an asterisk to indicate that all tty devices are matched by this entry.
|
|
|
|
|
The second field is a comma separated list of user names, or an
|
|
|
|
|
asterisk to indicated that all user names are matched by this entry.
|
|
|
|
|
The third field is a comma separated list of permitted access times.
|
|
|
|
|
.PP
|
|
|
|
|
Each access time entry consists of zero or more days of the week,
|
|
|
|
|
abbreviated \fBSu\fR, \fBMo\fR, \fBTu\fR, \fBWe\fR, \fBTh\fR,
|
|
|
|
|
\fBFr\fR, and \fBSa\fR, followed by a pair of times separated by
|
|
|
|
|
a hyphen.
|
|
|
|
|
The abbreviation \fBWk\fR may be used to represent Monday thru Friday,
|
|
|
|
|
and \fBAl\fR may be used to indicate every day.
|
|
|
|
|
If no days are given, \fBAl\fR is assumed.
|
|
|
|
|
.SH EXAMPLES
|
|
|
|
|
The following entry allows access to user \fBjfh\fR on every port
|
|
|
|
|
during weekdays from 9am to 5pm.
|
|
|
|
|
.br
|
|

|
|
.sp 1
|
|
|
|
|
*:jfh:Wk0900-1700
|
|
|
|
|
.br
|
|
|
|
|
.sp 1
|
|
|
|
|
The following entries allow access only to the users \fBroot\fR and
|
|
|
|
|
\fBoper\fR on /dev/console at any time.
|
|
|
|
|
This illustrates how the
|
|
|
|
|
\fI/etc/porttime\fR file is an ordered list of access times.
|
|
|
|
|
Any other user would match the second entry which does not permit
|
|
|
|
|
access at any time.
