Do you mean you want to lock an IP from not use your unigui application?

or do you want to lock computer by IP (lock windows screen)?

I want lock its IP that  computer don't  execute my web application.

I want to get access to that computer from the application.

On MainModule add Create evens as following:

procedure TMM.UniGUIMainModuleCreate(Sender: TObject);
var
  ip:string;
begin
  ip := unisession.RemoteIP;
  if ip = '192.1.1.1' then
    UniSession.Terminate('Not allowed');
end;

also look at the ServerModule for property BlockedIPList

also look at the ServerModule for property BlockedIPList

 

I use it,but when a user 3 time Mistakes in login credentials I block its IP,But all domain computers are locked.

I want recognize Which computer in  domain caused this mistake,and lock it.

Notice that I use my Web application On internet.

I pick up the local network IP, to exclude other machines from accessing cash register functions,

than the one having the physical connection to the receipt printer/cash drawer.

 

Notice the double backslash in the regex.

window.RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
var pc = new RTCPeerConnection({iceServers:[]}), noop = function(){};      
pc.createDataChannel('');
pc.createOffer(pc.setLocalDescription.bind(pc), noop);
pc.onicecandidate = function(ice)
{
  if (ice && ice.candidate && ice.candidate.candidate)
  {
    var myIP = /([0-9]{1,3}(\\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/.exec(ice.candidate.candidate)[1];
    ajaxRequest(MainForm.mainFrame, ['getLocalIP'], { IP : myIP });
    pc.onicecandidate = noop;
  }
};

window.RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;

Hi

 

This code is in C or Java?

It is Javascript, and you can load it from a textfile and assign it

to a uniHtmlFrame and then pick up the response in the AjaxEvent of the frame.

 

You can also inject the JS code at runtime, using the AddJS function (not tested):

uniSession.AddJS('window.RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;');
uniSession.AddJS('var pc = new RTCPeerConnection({iceServers:[]}), noop = function(){}; ');
uniSession.AddJS('pc.createDataChannel(""); ');
uniSession.AddJS('pc.createOffer(pc.setLocalDescription.bind(pc), noop);');
uniSession.AddJS('pc.onicecandidate = function(ice){ ');
uniSession.AddJS('if (ice && ice.candidate && ice.candidate.candidate) { ');
uniSession.AddJS('var myIP = /([0-9]{1,3}(\\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/.exec(ice.candidate.candidate)[1];');
uniSession.AddJS('ajaxRequest(MainForm.mainFrame, ["getLocalIP"], { IP : myIP }); ');
uniSession.AddJS('pc.onicecandidate = noop;  }}; ');

And then in the AjaxEvent:

procedure TMainForm.mainFrameAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);  

begin
  if eventname='getLocalIP' then 
  begin
    uniMainModule.localIP:=Params.Values['IP'];
    
  end;

Farshad: Would it be an idea to integrate this webRTC function into the mainmodule, so we can have the local IP as a client connects?

Hi,

How to fix regex format?

EDIT (Mar 2020): it looks like Firefox could be anonymizing local IPs as well.

As of March 2020, there are two settings in about:config page:

• media.peerconnection.ice.obfuscate_host_addresses - when set to true, it changes local IP to {uuid}.local
• media.peerconnection.ice.obfuscate_host_addresses.whitelist - string with URLs, which are able to retrieve real IP, even with obfuscation enabled

I've checked Firefox 73 and Developer Edition 74 (without any extension that could have changed the setting), first had obfuscate_host_addresses set to false, while dev edition had it enabled.

 

MacOS & Win10x64 firefox work with this settings.

on macOS, opera & safari not work.

not tested chrome any os.
