TsgcTURNServer

TsgcTURNServer is the server that implements the TURN protocol and allows you to process requests from TURN clients. The component inherits from TsgcSTUNServer, so all methods and properties are available on TsgcTURNServer.

 

TURN Server supports Long-Term Authentication, Allocation, Permissions, Channel Data and more.

 

Basic usage

Usually TURN servers run on UDP port 3478 and require Long-Term credentials, so in order to configure a TURN server, set the listening port (by default 3478) and start the server.

 

Configure the server

• Port: the listening Server port, example: 3478
• Define the Long-Term Credentials properties in TURNOptions.Authentication.LongTermCredentials
• Handle the OnSTUNRequestAuthorization to set the password when a TURN client sends a request to TURN Server.

 

Set the property Active = True to start the TURN server.

 

    oTURN := TsgcTURNServer.Create(nil);
    oTURN.Port := 3478;
    oTURN.TURNOptions.Authentication.Enabled := True;
    oTURN.TURNOptions.Authentication.LongTermCredentials.Enabled := True;
    oTURN.TURNOptions.Authentication.LongTermCredentials.Realm := 'esegece.com';
    oTURN.Active := True;
    procedure OnSTUNRequestAuthorization(Sender: TObject; const aRequest: TsgcSTUN_Message; 
      const aUsername, aRealm: string; var Password: string);
    begin
      if (aUsername = 'user') and (aRealm = 'esegece.com') then
        Password := 'password';
    end;
