1 This target can be used to identify when interfaces have been idle for a 2 certain period of time. Timers are identified by labels and are created when 3 a rule is set with a new label. The rules also take a timeout value (in 4 seconds) as an option. If more than one rule uses the same timer label, the 5 timer will be restarted whenever any of the rules get a hit. One entry for 6 each timer is created in sysfs. This attribute contains the timer remaining 7 for the timer to expire. The attributes are located under the xt_idletimer 8 class: 9 .PP 10 /sys/class/xt_idletimer/timers/<label> 11 .PP 12 When the timer expires, the target module sends a sysfs notification to the 13 userspace, which can then decide what to do (eg. disconnect to save power). 14 .TP 15 \fB\-\-timeout\fP \fIamount\fP 16 This is the time in seconds that will trigger the notification. 17 .TP 18 \fB\-\-label\fP \fIstring\fP 19 This is a unique identifier for the timer. The maximum length for the 20 label string is 27 characters. 21
