1This target can be used to identify when interfaces have been idle for a 2certain period of time. Timers are identified by labels and are created when 3a rule is set with a new label. The rules also take a timeout value (in 4seconds) as an option. If more than one rule uses the same timer label, the 5timer will be restarted whenever any of the rules get a hit. One entry for 6each timer is created in sysfs. This attribute contains the timer remaining 7for the timer to expire. The attributes are located under the xt_idletimer 8class: 9.PP 10/sys/class/xt_idletimer/timers/<label> 11.PP 12When the timer expires, the target module sends a sysfs notification to the 13userspace, which can then decide what to do (eg. disconnect to save power). 14.TP 15\fB\-\-timeout\fP \fIamount\fP 16This is the time in seconds that will trigger the notification. 17.TP 18\fB\-\-label\fP \fIstring\fP 19This is a unique identifier for the timer. The maximum length for the 20label string is 27 characters. 21.TP 22\fB\-\---send_nl_msg\fP 23Send netlink messages in addition to sysfs notifications and show remaining 24time. 25
