Detects the All-Seeing Eye service. Provided by some game servers for querying the server’s status.

The All-Seeing Eye service can listen on a UDP port separate from the main game server port (usually game port + 123). On receiving a packet with the payload “s”, it replies with various game server status info.

When run as a version detection script (-sV), the script will report on the game name, version, actual port, and whether it has a password. When run explicitly (--script allseeingeye-info), the script will additionally report on the server name, game type, map name, current number of players, maximum number of players, player information, and various other information.

For more info on the protocol see: <http://int64.org/docs/gamestat-protocols/ase.html&gt; <http://aluigi.altervista.org/papers.htm#ase&gt; <http://sourceforge.net/projects/gameq/&gt; (relevant files: games.ini, packets.ini, ase.php)

Example Usage

  • nmap -sV &lt;target&gt;
    
  • nmap -Pn -sU -sV --script allseeingeye-info -p &lt;port&gt; &lt;target&gt;
