ALTER TABLE `filter`
  ADD PRIMARY KEY (`callsign`);
COMMIT;

<?php
$_CONFIG = array();

//Datenbankkonfiguration
$_CONFIG["db"]["db"] = "aprs";	// Database
$_CONFIG["db"]["user"] = "root"; // DB-User
$_CONFIG["db"]["pass"] = "********"; //DB-Password
$_CONFIG["db"]["host"] = "10.0.0.141"; //DB-IP

$_CONFIG["db"]["packettable"] = "packets"; //Packet Table
$_CONFIG["db"]["filtertable"] = "filter"; //Filter Table

//APRS Spezifische Einstellungen
$_CONFIG["aprs"]["maxage"] = 60; // in minutes
$_CONFIG["aprs"]["maxrecords"] = 1000; // max shown objects
$_CONFIG["aprs"]["purgeafter"] = 48; // in hours
