Hi Diab,

There is no server in wodVPN. wodVPN is a peer-to-peer component which means that connection is established directly. The only server used is mediator which is used for matching Peer IDs and exchanging IP/Port. Mediator only keeps info IPs for 15s and removes them afterwards. Mediator *doesn't* have to be used if you already know IP/Port info.

You can check following URL in order to see a sample of Mediator script: http://www.weonlydo.com/VPN/Help/Mediator.html

As for communication itself, UDP packets are used, and connection is encrypted so noone beside peers can read the data (not even mediator). Also, wodVPN uses UDP hole-punching technique in order to pass through firewalls (*I would suggest you try searching on internet for more info on this term*).

Hope this helps.

Diab,

Yes you can. That's why I provided Mediator script URL. You can simply place it on your own server.

You don't need to do that. You simply call Search method and mediator does the exchange.

Diab,

Did you try installing component? When you install wodVPN, you should have Samples installed along. There are .Net samples included.

Can you please try them out?

Diab,

You can use any application type you like. It's only important that you can import wodVPN inside and run mediator there using wodVPN VPNMediator Object.

Here is code snippet how to start your own mediator.
[code]WODVPNCOMLib.wodVPNCom med;
private void Form1_Load(object sender, EventArgs e)
{
med = new WODVPNCOMLib.wodVPNCom();
med.MediatorConnected += new WODVPNCOMLib._IwodVPNComEvents_MediatorConnectedEventHandler(med_MediatorConnected);
med.Mediator.Start(WODVPNCOMLib.SearchEnum.SrchUDPSingle,8000);
}

void med_MediatorConnected(string IP, int Port, string FromID, string ToID, string Data, ref bool Allow)
{
Allow = true;
}[/code]
You need to point peers to connect to your mediator inside Search Method.

Let us know how it goes.

Diab,

Saying didn't work doesn't really help. What happened? Did you receive an error? Which error did you receive?

What sample did you use? Did you use Drazen's code for Mediator, or the Mediator code in Samples directory? Did you adapt the code to use Port 90?

1-i use your C#Sample to connect with two peers, it works when the application using your Mediator search but when i make my server with your code (put it in console app )with your code , there is no error happen but the connection doesn't establish with the two peers.

2- i tried to use your Application (WODVPN Sample)to connect without searching (writing the public ip address and the port that the other peer is listen to ) but the connection is timeout.

Diab,

When you say sample , please be specific. Which sample exactly?

Did you change the Port and mediator hostname/IP in Search method call?

I'm so sorry that you didn't understand me.
In C# Folder there is a 1simple Application that i took about.
i chaneged
wodVPN1.Search(WODVPNCOMLib.SearchEnum.SrchUDPSingle, textBox2.Text, myserver.com , 90, null);
that Search Method to my server
First : i want to Connect two peers without calling your server by writing each public ip in the hostname Textbox and the port textbox
When i did it, the problem is Connection timeout

Second: using my server in searching peers and establishing the connection between the peers, used your Sample code to make mine but the server didn't get the peers list >

i'm sorry For that again
and Thanks a lot for your Support

Diab

it is simple Application that(like Chat Application)

Diab,

Ok.

#1: In that case you can simply enter Hostname and Port fields (and enter public IP and Port) and click Connect. Please keep in mind that Port needs to be open if computers are behind a firewall.

#2: If I understood right, it works with our mediator specified? If so, then are you sure that your mediator is even running? Is it publicly accessible?

i tried to host a website on my open port in the server (Port 90) and it works. i think that the logic behind the code in the server is very simple, it just use the Mediator and start it in my port , is there is any logic in the server side code ?

There *IS NO* server. There's only Mediator, and 2x Peers. Peers contact mediator only to exchange IP/Port of the other peer. Once matched, they connect. Connection is made directly between peers, without any 3rd party in between.

What's the network and hardware requirements to build my mediator ?

Diab,

There is no special requirements for running mediator. Mediator doesn't use much memory so it should work on normal machine without any problem.

You need to have access on Internet on machine where you run mediator. There is no other network requirements.

I have a static ip server and i'm trying to test Your Sample (simple C# Application in my server , i run two instances in the same server and make Search Button ,it returns Timeout... the same application works in the clients)my server access the internet but the ports that opened are 90 ,8000.
Are there any Security issues that would be a problem in my server?
my server can't connect to your Medaitor.weonlydo.com .
Note: i Closed my firewall.

Thanks a lot

Diab,

Mediator.weonlydo.com is online. Probably you have some firewall or something similar that blocks connection to our mediator.

Can you maybe check this out and try it again? Mediator.weonlydo.com is on port 8000.

the code that i used in a console Application in the server

WODVPNCOMLib.wodVPNCom med = new WODVPNCOMLib.wodVPNCom();
med.MediatorConnected +=new WODVPNCOMLib._IwodVPNComEvents_MediatorConnectedEventHandler(med_MediatorConnected);
med.Mediator.Start(WODVPNCOMLib.SearchEnum.SrchUDPSingle, 8000);
Console.WriteLine( Start );
Console.ReadLine();

this is in the server
and the client
wodVPN1.Search(WODVPNCOMLib.SearchEnum.SrchUDPSingle, textBox2.Text, MyPublicIPServer , 8000, null);
