Bind resource to an IP

[Decro]

Hello there.

I've seen that some people selling their resource with closed code and IP-binding. So you can run this resource only on the server which is running on defined IP address. And well, those resources is not requiring an ACL right's to check the server current IP, so they're somehow getting it without any callRemote() functions. And my question is: how do i get the server current IP address without calling any remote requests? Or maybe, is there any other way to prevent resource from starting on differ PC's?

You can make your own script, which is loaded before the encrypted script. You can overwrite functions in your own script to output the URL in debug and then spoof the result whenever the encrypted script does a callRemote.

-- Store the original function
local _callRemote = callRemote

-- Overwrite the global function for our purpose
function callRemote(url, a, b, c, d, ...)
    outputDebugString(("callRemote(%q, ...)"):format(url))
    
    -- Should we spoof the result?
    if url ~= "<url which returns ip>" then
        return _callRemote(url, a, b, c, d, ...)
    end

    -- callRemote(url, callback)
    if type(a) == "function" then
        return callback("<fake data from url>", 200, b, c, d, ...)
    end
    
    -- callRemote(url, attempts, callback)
    if type(b) == "function" then
        return callback("<fake data from url>", 200, c, d, ...)
    end

    -- callRemote(url, attempts, timeout, callback)
    if type(c) == "function" then
        return callback("<fake data from url>", 200, d, ...)
    end

    -- callRemote(url, queueName, attempts, timeout, callback)
    if type(d) == "function" then
        return callback("<fake data from url>", 200, ...)
    end
end
