- This target can be used to identify when interfaces have been idle for a
- certain period of time. Timers are identified by labels and are created when
- a rule is set with a new label. The rules also take a timeout value (in
- seconds) as an option. If more than one rule uses the same timer label, the
- timer will be restarted whenever any of the rules get a hit. One entry for
- each timer is created in sysfs. This attribute contains the timer remaining
- for the timer to expire. The attributes are located under the xt_idletimer
- class:
- .PP
- /sys/class/xt_idletimer/timers/<label>
- .PP
- When the timer expires, the target module sends a sysfs notification to the
- userspace, which can then decide what to do (eg. disconnect to save power).
- .TP
- \fB\-\-timeout\fP \fIamount\fP
- This is the time in seconds that will trigger the notification.
- .TP
- \fB\-\-label\fP \fIstring\fP
- This is a unique identifier for the timer. The maximum length for the
- label string is 27 characters.
