The engine of MCServer is not LUA, so you have to use Java, I think. o.O

I think he wants the plugin to gather some data from the server.
You would need a lua module included by MCServer for this to work,
or I think loading the luasockets module from within lua.

I already created something for this, and exported it to Lua

Code:
class cTCPLink
{

public:
        cTCPLink();
        ~cTCPLink();
        bool Connect( _cstring  a_Address, unsigned int a_Port );
        int Send( _cstring  a_Data, unsigned int a_Size, int a_Flags = 0 );
        int SendMessage( const _cstring  a_Message, int a_Flags = 0 );
        void CloseSocket();
protected:
        virtual void ReceivedData( char a_Data[256], int a_Size ) = 0;
};

It's not documented anywhere. You basically need to 'extend' it like you extend cPlugin. You need this piece of code for that:

Code:
local TCPLink = {}
TCPLink.__index = TCPLink

function TCPLink:new()
   local t = {}
   setmetatable(t, TCPLink)
   local w = Lua__cTCPLink:new()
   tolua.setpeer(w, t)
   w:tolua__set_instance(w)
   return w
end

Then you can inherit the ReceivedData function like so:

Code:
TCPLink:ReceivedData( Data, Size )
   -- Do stuffs with data
end

Okay im a tad confused as i only ever use pure lua and gmod lua, So what exactly do i need to do with this code?

Here's an example:

Code:
local TCPLink = {}
TCPLink.__index = TCPLink
function TCPLink:new()
   local t = {}
   setmetatable(t, TCPLink)
   local w = Lua__cTCPLink:new_local() -- new_local = Deleted by garbage collector
   tolua.setpeer(w, t)
   w:tolua__set_instance(w)
   return w
end

TCP = TCPLink:new()
if( TCP:Connect("www.mc-server.org", 80) == true ) then
	Log("Sending message")
	TCP:SendMessage("GET http://www.mc-server.org/\n")
end

function TCPLink:ReceivedData( Data, Size )
	Log("Received data: " .. Size )
	String = string.sub( Data, 0, Size )
	Log( String )
end
