For benefit of others, as discussed over email with Victoria already, this won't help. Improvements are needed to WinSCP to allow authentication with an empty password.

I have sent you an email with a development version of WinSCP to address you have used to register on this forum.

The difference is that GUI asks for a password and I leave the password field empty, click on connect btn and connection happens
and I see file viewer.

GUI do this :

But code logs:

. 2015-02-03 11:50:28.776 Prompt (7, SSH password, , &Password: )

And I hope you really know, what you are doing, when using .GiveUpSecurityAndAcceptAnySshHostKey.

Yes, this is ok.

Also I can connect and send file by pscp.exe using:
pscp.exe -scp -pw "" C:\Users\user1\Desktop\333.prj root@10.0.6.10:/mnt/ufs/root

So, I realy mean that I have access and there is no password or maybe empty password, but with some reason that does not work on winScp dll :(

ps. sry for my english

Re: Disconnected: Unable to authenticate

So how do you authenticate in GUI? I assume you do not really allow root access with no authentication at all.

And I hope you really know, what you are doing, when using .GiveUpSecurityAndAcceptAnySshHostKey.

Disconnected: Unable to authenticate

Hi.

I want to connect to server with scp protocol and I can do this by WinScp.exe.
But c# code does not work =(

username = "root" and there's no password

Here's my code: 

// Setup session options

var sessionOptions = new SessionOptions

{

    Protocol = Protocol.Scp,

    HostName = "10.0.6.10",

    UserName = "root",

    GiveUpSecurityAndAcceptAnySshHostKey = true,

};



using (var session = new Session()

        {

            SessionLogPath = Path.GetFullPath(@".\WinScpSessionLog.txt"),

            DebugLogPath =  Path.GetFullPath(@".\WinScpDebugLog.txt")

         })

{

    // Connect

    session.Open(sessionOptions);

}


Here is SessionLog

I tried to set password as empty string in SessionOptions - does not work.

Please tell me how to connect with "root" and no password.
I say again - I can connect with WinScp.exe
