I decided a few minutes ago that I’d like to make AudioProbe a bit less appetizing to stream rippers. Here’s the result:
First, create shoutcast-config.php
This file holds all of the configuration details for your shoutcast servers. I keep this in a separate file since I include this in other applications on the site. You can add as many servers as you want.
<?php //server config...you can add as many servers as you want in following format...just simply copy and paste this code block to add a new server (update the info of course) $serv["host"][] = "listen.audioprobe.net"; # host address # port IP address $serv["port"][] = 80; # port number $serv["passwd"][] = "pass"; # admin password ?> |
Create ban.php:
<?php //import our list of server(s) require_once('shoutcast-config.php'); //our banned useragents...feel free to add as many as you'd like $banneduas=array("WinampMPEG/5.0", "WinampMPEG/5.50"); //if you would like to ban the IP in addition to kicking it, set this to TRUE $ban=FALSE; /***************************************************/ //Do NOT touch below this line /** * xml2array() will convert the given XML text to an array in the XML structure. * Link: http://www.bin-co.com/php/scripts/xml2array/ * Arguments : $contents - The XML text * $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value. * $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. * Return: The parsed XML in an array form.

You can set this to run periodically by using a Cron job. Your host should be able to assist you with setting it up. For example, on a cPanel server, the command would be this:
/usr/bin/curl -s http://YOURDOMAIN/ban.php >/dev/null 2>&1 |
Enjoy and please let me know if you find it useful! 🙂
