release Starter Name Verification Function

[Black_Rose©]

In this discussion, we’ll delve into a specific function designed to verify the starter name of the client application (not the version). If the startup name isn't defined in the source code, the connection will be automatically terminated. This function is particularly effective for the FREE or TEST versions of a server framework. Currently, it is leveraged by several developers to incentivize users to purchase the source code.

Code Modification Steps

If you need to make changes to this function, here's a step-by-step guide:

1. Navigate to your server's source directory:
   Go to /usr/src/your_source/game/src.

2. Open the file named input.cpp and search for the following function:

  • Sign Up

  Note: The function could be absent or commented out to bypass the verification.

• If found, replace the existing code with this:

Explanation of the Code

• Character Check: The first step in the function ensures that the character reference (ch) is valid; if not, it exits the function immediately.

• Packet Handling: The function then casts the incoming data into a TPacketCGClientVersion structure for further processing.

• Filename Validation: It checks whether the filename is not "Starter.exe" and confirms that the player does not have the status of GM_IMPLEMENTOR. If either condition fails, the player's connection is closed, and a message is logged.

• Logging Version Information: If the player passes the checks, the function logs the character's name, timestamp, and filename, then updates the client's version.

 

By implementing this verification process, server administrators can effectively manage client connections and ensure that only legitimate users engage with their environment. This is a crucial step in enhancing security and encouraging users to secure the complete version of the software.
