This target can be used to identify when interfaces have been idle for a
|
|
Packit |
7b22a4 |
certain period of time. Timers are identified by labels and are created when
|
|
Packit |
7b22a4 |
a rule is set with a new label. The rules also take a timeout value (in
|
|
Packit |
7b22a4 |
seconds) as an option. If more than one rule uses the same timer label, the
|
|
Packit |
7b22a4 |
timer will be restarted whenever any of the rules get a hit. One entry for
|
|
Packit |
7b22a4 |
each timer is created in sysfs. This attribute contains the timer remaining
|
|
Packit |
7b22a4 |
for the timer to expire. The attributes are located under the xt_idletimer
|
|
Packit |
7b22a4 |
class:

When the timer expires, the target module sends a sysfs notification to the
|
|
Packit |
7b22a4 |
userspace, which can then decide what to do (eg. disconnect to save power).
