How Server can connect to client over the internet with tcp

7 posts in this topic

i am trying to figure out how a server can connect to a client Over the internet. 

In this is script. The client connects to the server on the same machine (localhost) and executes the commands from the client.

How can I change that instead communicating over localhost to communicate over the internet with tcp ipaddress and a port.

 

What i actually need help of is

1. The server will open a port and  listen to communication from a No-ip address

2. I input the no-ip address and correct port in the client side, and when i click on connect, it connects to the server if its online

 

 

This is the client

#include <GuiConstantsEx.au3>
THIS IS THE CLIENT

#include <NamedPipes.au3>
#include <StaticConstants.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

So, the major issue here is going to be whether or not the server IP and port are in fact internet accessible.  Is the "server" in the cloud/accessible from the internet as far as you know?  If the "server" sits behind a firewall (i.e. via business or home ISP), the firewall will need to be configured to pass traffic to the server (i.e. port forwarding/triggering, DMZ, etc.)

i will configure it to allow it since is my own computer but in my second home.

 

my problem here  is how i can make them connect to each other and receive the commands. 

since the code i posted only allow localhost connection. 

How can i connect from the client to the server with an external ip of the computer the server is installed on.

 

Thank you

Well, you mentioned No-Ip, so you would/could use that to tie your external IP to a Domain Name (URL).   Then it's just a matter of configuring your home router/firewall to do either port forwarding or triggering.

Instead of the period "." (denotes local), you should be able to replace it with an IP or resolvable hostname (Domain Name).

I want the server to receive connection from only my no ip adrees..

in a the case where

 

1. if the server is running then it waits for remote connection from my no ip address.

2. so i set the no ip address on my computer and runs the client , the server on my home computer will connect back to it automatic if is online.

      I have had several people ask for this, so I decided to work the algorithm for it and this is the result.
      What is it?
      A Gateway Proxy Sends and Receives Data Unmodified.
      https://en.wikipedia.org/wiki/Proxy_server
      What is it used for?
      You can use it as a gateway, relay or router between two known static IP addresses.
      More information is in the header of the script.
      Download: LocalGatewayProxy.au3
      You will need WSA_NBTCP.au3 from here:
      https://www.autoitscript.com/forum/topic/191954-wsa_nbtcp-v100-udf/
      If you have any questions or problems, let me know.

      This script is based on algorithm code from EnrMa.
      Updated: January 22, 2018
      Made improvements. Changes are in the script header.

      WSA_NBTCP.au3  (Windows Sockets API - Non-Blocking Transmission Control Protocol)
      Version: 1.00
      Type: UDF
      This is an accumulation of WSA code from many sources and modified to suit myself.
      These functions have been thoroughly tested using a Local Proxy Server, which
      is about the most strenuous test you can use.
      Includes my rendition of how a TCPRecv Timeout should work. Also includes a
      timewait/timeout using Select for TCP Send, which works great for that function.
      You will need a loop to use _WSA_TCPRecv(). An example will be forthcoming in a second post.
      Functions:
      #CURRENT_USER_FUNCTIONS
      _WSA_Cleanup
      _WSA_FormatMessage
      _WSA_GetLastError
      _WSA_TCPAccept
      _WSA_TCPCloseSocket
      _WSA_TCPConnect
      _WSA_TCPListen
      _WSA_TCPRecv
      _WSA_TCPSend

      #INTERNAL_FUNCTIONS
      __TimeoutManager
      __TimeoutReset

      #EXTRA_FUNCTIONS
      _WSA_GetAddrInfo
      _WSA_GetHostByAddr
      _WSAAsyncGetHostByName
      _WSAAsyncGetHostByName_Callback
      _WSA_GetNameInfo
       
      Requirements:
      - AutoIt Versions: 3.3.8.1 thru 3.3.15.0 (32Bit only).
      - TCPStartup() at beginning of script on startup.
      - TCPShutDown() and _WSA_Cleanup() on exit.

      It is not possible to Broadcast/Emit objects Only 1D-arrays are allowed to be Broadcasted/Emitted (2D arrays will probably never be supported) Changelog
      Version 1.5.0 (This update DOES NOT break scripts)
      Added AutoIt like docs under Docs\. The docs are generated so its a 1 to 1 reflection of the UDF headers. Print of documentation Added a production ready server example. Added a new method: _Io_DevDebug which will display useful information when debugging. Added a new method: _Io_SetMaxRecvPackageSize which defaults to whatever _Io_setRecvPackageSize is set to. Added a new method: _Io_setOnPrefix which defaults to _On_ Added a new default client & server event called flood. Flood occurs when exceeding the $__g_io_nMaxPacketSize. $__g_io_nMaxPacketSize is set by _Io_SetMaxRecvPackageSize Fixed the 16 parameter limit when sending data with _Io_Emit, _Io_Broadcast, _Io_BroadcastToAll and _Io_BroadcastToRoom. This works on the same premise that AutoIt's Call Does Fixed a TRUNCATION problem when receiving packages which could cause crashes! Fixed a programming error which caused $__g_ionPacketSize to reset to default 4096 if _Io_Connect or _Io_listenwere called after _Io_setRecvPackageSize Fixed _Io_setEventPreScript and _Io_setEventPostScript They didnt work. Lol. Changed how events are fired so the client cannot crash the server by sending the wrong number of parameters (This also allows for optional parameters on callbacks) Changed _Io_On. The second parameter $fCallback can now be set to null. Doing this, the function assumes that the callback is: _On_<eventName>.

      Good evening guys,
      i'm having a problem, not about the code (i'm only thinking about it at the moment) but about the way i can do it.
      I have a webpage (photo N.1) it has some elements in it.
      I need only the table (photo N.2), looking at the code and with _IEFunctions i can easy find the table but how i can i "copy" it?
      As i said it's really easy to found with a script but what should i do then? Copy the source? And how can i display it to the user?
      In my head i'd like to display it inside a GUI, is that possible?
       
      Thanks in advance
       
      Edit: Posted 2 times same photo. Now should be OK
