On this page I will present a small (75 lines) PHP service dedicated to storing and querying beacons by VpnCloud.
The PHP script is very simple and has the following requirements:
- PHP 7.0+
- Sqlite3 PHP module
- Writable storage for the Sqlite DB
The setup of this service is pretty simple: download the PHP script and put it on a server that meets the requirements. Make sure that the database is writable by the webserver user. Thats it.
If you want, you can protect the database file using a
.htaccess file, so that it cannot be downloaded as a whole. But since the information is not secret and encrypted anyhow, this is not necessary.
If you do not have a public server or do not want to host this service, you can use the service running on this server at:
On each node
wget is required to store and query beacons.
The PHP script allows storing beacons via HTTP POST requests:
beacon: store: '|wget -O - --post-data "beacon=$beacon" http://your.server.com/beacondb.php'
Loading beacons can be done very efficiently, as the service offers filtering via prefix:
beacon: load: '|wget -O - http://your.server.com/beacondb.php?net=$begin'
