Hi,

I need to work on Implicit secure ftp connection over the web. Here the code which does the authentication

fc.Connect(ftpaddr);
fc.Authenticate(AuthenticationMethod.tls, VerificationFlags.None, null, DataChannelProtection.Private);

if (fc.Connected)
{
     if (usrname.Trim() == "")
     fc.Login(null, null);
     else
     fc.Login(usrname, pwd);

     foreach (string file in filelist)
    {
      fc.SendFile(file);
    }
}

But it sends the AUTH TLS command. I dont want to send AUTH command to the connection.

Could you please help me, how to do the Implicit Secure FTP.

Hi,

I was able to fix the issue. Gave the authentication method on connect parameter itself. then it started to work. I don't know what is the difference between authenticating on connect and after connect trying to do the authenticate.

--Thx

Hi Rajkumar, 

There are 2 types of secure connections: "Implicit" and "Explicit".

In "Implicit connections", you pass the AuthenticationMethod as a paramater to Connet() method, and you dont need to call the Authenticate() method after, simply the Login()  method.
Code Sample:
    client.Connect( servername, AuthenticationMethod.Ssl, VerificationFlags.None, null );
    client.Login( username, password );

In "Explicit connections", you must call the Connect() method without SSL parameters, and then call the Authenticate() method later on before calling the Login() method.
Code Sample:
    client.Connect( servername );
    client.Authenticate(AuthenticationMethod.Ssl, VerificationFlags.None, null, DataChannelProtection.Private );
    client.Login( username, password );
