.SH "名称"
porttime \- 端口访问时间文件
.SH "描述"
.PP
\fIporttime\fR
contains a list of tty devices, user names, and permitted login times\&.
.PP
每项包含三个由冒号分隔的字段。第一个字段是逗号分隔的 tty 设备列表，或者星号表示匹配所有终端。第二个字段是逗号分隔的用户名列表，或者星号表示匹配所有用户名。第三个字段是逗号分隔的访问许可时间。
.PP
Each access time entry consists of zero or more days of the week, abbreviated
\fISu\fR,
\fIMo\fR,
\fITu\fR,
\fIWe\fR,
\fITh\fR,
\fIFr\fR, and
\fISa\fR, followed by a pair of times separated by a hyphen\&. The abbreviation
\fIWk\fR
may be used to represent Monday thru Friday, and
\fIAl\fR
may be used to indicate every day\&. If no days are given,
\fIAl\fR
is assumed\&.
.SH "示例"
.PP
The following entry allows access to user
\fBjfh\fR
on every port during weekdays from 9am to 5pm\&.
.PP
*:jfh:Wk0900\-1700
.PP
The following entries allow access only to the users
\fIroot\fR
and
\fIoper\fR
on
/dev/console
at any time\&. This illustrates how the
/etc/porttime
file is an ordered list of access times\&. Any other user would match the second entry which does not permit access at any time\&.
