VPN/Proxy Blocker

#1

Post by Pdv72 » 3 years ago

Hi,
There is a plugin it's job to block any detected client who's using Proxy/VPN.
But the problem is that this plugin appears as "Running" But it does not doing it's job. like checking client and punishing fake client and the legit client don't gets punished.
Plugin Code:
Code: [Select all] [Expand/Collapse]
  1. #include <amxmodx>
  2. #tryinclude <grip>
  3. #include <nvault>
  4.  
  5. #pragma semicolon 1
  6.  
  7. #if !defined _grip_included
  8.     #assert "gRIP module is required! https://dev-cs.ru/resources/650/"
  9. #endif
  10.

  16.

  18.         set_fail_state("nvault Error: Vault wasn't opened!");
  19.         return;
  20.     }
  21.    
  22.     get_localinfo("amxx_datadir", g_szDataDir, charsmax(g_szDataDir));
  23.     add(g_szDataDir, charsmax(g_szDataDir), "/proxycheck");
  24.    
  25.     if (!dir_exists(g_szDataDir)) {

Good idea to put some limitations on cheaters.

For those who does not know how this works, the plugin require a module called: grip. The author build this module for Linux only, you will need to build this module for windows if you need to run this blocker on windows. Don't forget to write grip in modules.ini.

The plugin will kick any player who uses VPN. Also please note that in logs directory, you will find a file named VPN-Detected.log, in this file you can see Name & IP of players who used VPN and got kicked previously.

Download the .SMA/.AMXX + Module: If you need only the code:
