This is a away to you protect your amxx files.
I had some requests about it. Some people using "untrustable" hosts, sharing FTPs etc.

With this way, it still being possible to make the plugin run in others servers, but is more complicated and in some cases may be impossible to do it with regedit.

Since i dont have much time i will try to hurry. Later i might fix some things, explain better etc.

Example with IP: 77.111.197.790:27015

PHP Code:

#include <amxmodx>

// With this IP you have the numbers- 7 | 1 | 9 | 0 | 2 | 5
// You also need to add the characters- . | :
// Total: 8 characters
// So you will make: The const with value 8
new const IPX[8][] = {
    ".", // This will be: IPX[0]
    ":", // This will be: IPX[1]
    "7", // This will be: IPX[2]
    "1", // This will be: IPX[3]
    "9", // This will be: IPX[4]
    "0", // This will be: IPX[5]
    "2", // This will be: IPX[6]
    "5" // This will be: IPX[7]
}

new SERVER_IP[22] // This is for get server IP

public plugin_init() {
    register_plugin("Plugin", "Version", "Author")
    
    get_user_ip(0, SERVER_IP, 21, false) // Getting server IP with Port
    
    // Ok, now you can build server IP with formatex
    new PROTECTED_IP[21] // Since the IP in example has 20 characters in total (counting the repeated ones), lets make here 21
    // Since the IP has 20 characters, you need 20 %s at formatex
    formatex(PROTECTED_IP, charsmax(PROTECTED_IP), "%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s", /*77*/IPX[2], IPX[2], /*.*/IPX[0], /*111*/IPX[3],
    IPX[3], IPX[3], /*.*/IPX[0], /*197*/IPX[3], IPX[4], IPX[2], /*.*/IPX[0], /*790*/IPX[2], IPX[4], IPX[5], /*:*/IPX[1], /*27015*/IPX[6], IPX[2], IPX[5], IPX[3], IPX[7])
    
    // OK! Now you have the server IP, and Protected IP
    // Time to check if is not equal to the server IP
    if(!equal(PROTECTED_IP, SERVER_IP))
    {
        new error[100]
        formatex(error, charsmax(error), "[IP PROTECTION] You are not allowed to run this plugin!")
        set_fail_state(error)
        return
    }
}

If I recompile AMXX using

PHP Code:

static cell AMX_NATIVE_CALL set_fail_state(AMX *amx, cell *params){
    return 0;
} 


But, if your code is at the top, the "return" statement will stop plugin_init execution, so the plugin won't work as expected. In that case I would recompile AMXX with a console message inside "equal"'s native, so I can know what are you comparing, then I only need to add a condition that if the param 1 is your ip, the functions returns true).

At least use an infinite loop to crash the server and a loop to check if the string matches your ip. Of course it won't be 100% secure, but it will be harder.

No it will not, certain forwards ignore the return value, plugin_init being one of them. Plus, an empty return is the same as doing "return 0".

Oh, and simply editing get_user_ip to throw an error if the index is 0 would be much easier.

To comply with the GPL you need to ship your private plugins with the source code included, which means that the user can easily edit this code out. It only has a purpose if you intend to break the AMXX license.

Not really, if you going to sell a plugin breaking the license, you wouldnt really set a IP protection.

Like stated in first post. There are many ways your amxx can get leaked/stole.
Bad host, ftp share, even teamviewer.

If you have some plugin in desktop. Ofc you can see him transfering, but is too late since it does it fast.
Idk about recent versions of team viewer since i dont give much use of it recently, but before you didnt need to authorizate the downloads. So yeah, it can even be stole via teamviewer

I would call that simply a really bad choice by you if you were to open up your computer to someone you don't know or can't trust. So, it is not the fault of TeamViewer but rather the fault of the person giving full access to your computer to someone that you can't trust.

Also, who keeps plugins on their desktop?

get_user_ip for index 0 returns the value of a cvar (net_address), not the real IP.
