Title: Preventing unpatched clients from entering your server
Post by: osler on February 18, 2014, 12:39:15 am

How does this work?

   If the player is using a non modified wow.exe the authserver will reject his login petition.
   If th player is using a modified wow.exe but not a custom patch this error will appear:

Required tools:

• Hex editor
• Text editor
• wow.exe patcher viewtopic.php?f=59&t=883 (http://modcraft.io/viewtopic.php?f=59&t=883" onclick="window.open(this.href);return false;)

How to do it:

• Change client build ( viewtopic.php?f=26&t=860 (http://modcraft.io/viewtopic.php?f=26&t=860" onclick="window.open(this.href);return false;) ) and make the auth server accept it. https://github.com/TrinityCore/TrinityC ... hCodes.cpp (https://github.com/TrinityCore/TrinityCore/blob/master/src/server/authserver/Authentication/AuthCodes.cpp" onclick="window.open(this.href);return false;) (I'm not sure since I've never done this server modification)
• Open wow.exe with a hex editor and look for the string "DefaultServerLogin" and modify it in any way. I'll be using "DefaultServerDogin".
• Open AccountLogin.lua and repeat step two in this file (Line #172)
• Pack the Lua file in a .mpq file and distribute it and the modified wow.exe

This is really cool, especially when your spawn zone is in a custom area. I'll try it out sometime. Thanks :)
