| + | ====== Download a Remote Config File and Delete it afterwards ====== | ||
| + | |||
| + | A very simple Method to roll out configfiles on a bunch of Router: | ||
| + | |||
| + | The Router will try to download a config file from a ftp server with a unique part in the URL. | ||
| + | After the File was downloaded successfully it will be deleted on the remote ftp server. | ||
| + | |||
| + | This way you won't have a endless download. | ||
| + | |||
| + | This Script can be used with various triggers: periodicly every XX min, after wan-up, sdk-startup and so on | ||
| + | |||
