Track traffic across interface and device restarts and limit
|
||
|
|
consumption to a donation-backed amount.
|
||
|
|
|
||
|
|
To increase SSD lifetime persistent storage is only touched every
|
||
|
|
$MaxPerTrafficDiff bytes (currently 100 MB). So tracking can be
|
||
|
|
trivially avoided by frequent router reboot.
|
||
|
|
|
||
|
|
* Usage
|
||
|
|
- call traffic_track via cron as often as possible
|
||
|
|
- call traffic_account_donation to increase the traffic limit
|
||
|
|
after you put the coin in the treasure chest
|
||
|
|
|
||
|
|
* Internals
|

|
** Counters
|
||
|
|
- Max :: traffic limit
|
||
|
|
- Per :: traffic accounted to disk
|
||
|
|
- Eph :: traffic acounted to /tmp
|
||
|
|
- Cur :: traffic directly obtained from `ip -s`
|
||
|
|
- Obs :: part of Cur already accounted
|
||
|
|
** Caveats
|
||
|
|
- scripts are non-reentrant
