Parsing a darkstat database with PHP

Posted by

This is something I wrote for the sake of interest more than necessity but I have found it quite useful for manipulating the data from a darkstat database since then. It’s not particularly elegant in such that it’s just a bunch of global functions but it’s a decent start if you want to wrap it in a class.

You can get the code here.

  1. Wow! I searched for this with zero hope and someone did it! Thank you! I plan to move these functions in a class. I’ll send you the improved code once I’m done with this.

  2. Hello !

    I’m using darkstat for an important school project, and I’m trying to use the darkstat.db file. Unfortunately, it’s unusable directly, so I searched how to parse it correctly. I found your post, tried your php code, but unfortunately, it doesn’t work. Your program find the headers correctly, but dies with the ‘I don’t know this address family’ error. I tried to figure out why, but unsuccessfully. I wonder if your code may be obsolete.
    I guess darkstat developers have changed the way darkstat write its database.
    So I would like to ask you if you are aware of some improvements, or if you had improved your code yourself. If you had, may I ask you if you can update your post, or share your latest version ?
    Thanks a lot in advance !

    1. Hi! Tom,
      I managed to make this code working by modifying two line. Here are the diff result, FYI:
      scotthsiao@ubuntu /tmp/darkstat $ diff ds_parser.php ../ds_parser_ori.php
      15,16d14
      <
      “\x04”, 6 => “\x06”);

      < $ip[] = bin2hex(fread($db, 2));
      $ip[] = bin2hex(fread($db, 8));

      global $versions, $protocols;
