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. |
|
.TP |
|
\fB\-\---send_nl_msg\fP \fI(0/1)\fP |
|
Send netlink messages in addition to sysfs notifications and show remaining |
|
time. Defaults to 0.
