The $$ should not be a problem. Can you connect with GUI?

i can connect using the full gui application

Enable password logging and compare the password in GUI and scripting session.

I logged the steps from the GUI screen and i notice the following
what is the syntex for handing Private key and "SSH key passphrase"

So are you authentication with password or private key (encrypted with a passphrase)?

If with private key encrypted with a passphrase, use -passphrase= switch:

Hi, I am in a similar situation mentioned in the thread below. While authenticating using command line option, it fails Authentication. Same password is fine using interactive Logon using WinSCP (I did a paste of the same password) as well as it is fine in GUI.

But when we include the script in command line option then the authentication fails. When Log was enabled, it was noticed that the character + in the password was replaced with a space. I tried placing the character as %43 with its ASCII code but that failed too.

Any idea how to succeed through the authentication process?

Any help is much appreciated.

Hi Martin,

That has worked wonderfully well. I noticed that the special characters are mentioned with the Hex equivalent where as I have been trying with decimal ones. The automatic generation of script is a very handy feature of the application. Thanks to the developers and Thank you very much for the support.

Hi,

I'm facing below error while using WinSCP assembly in my c# code

Connection has been unexpectedly closed. Server sent command exit status 0.
Authentication log (see session log for details):
Unable to use key file "PuTTY-User-Key-File-2: ssh-rsa

Using username "m79971".

Authentication failed.

Attaching my code snippet.


Your quick response on this will be highly appreciated. Thanks in advance.

The $$ should not be a problem.

Can you login in WinSCP GUI or using any other SFTP/SSH client?

Yes I'm able to login successfully from GUI.

So enable password logging and check both GUI and script log for an actual password being used.
GUI: https://winscp.net/eng/docs/ui_pref_logging
Script: Use /loglevel=*

SOLVED MY SPECIAL CHARACTER PROBLEM BY TURNING OFF setlocal ENABLEDELAYEDEXPANSION IN THE BATCH FILE. I HAVE ! IN THE PASSWORD.

THANKS MARTIN.
