This article provides information related to the use of the SCP protocol while utilizing the SSH Server on the Windows platform.


  • All NCM versions
  • SSH Server (SCP/SFTP server which comes with NCM or 3rd party server)


While utilizing SCP for config backup, NCM will experience an authentication error. This issue is related to the Windows system itself as the functionality works fine on Unix-based systems.


While testing download in NCM,  the following error will be shown in Transfer Status grid:


Error Downloading Config to SCP Host: X.X.X.X




While using a standalone SCP client for testing, for example WinSCP, the following error appears:


Server refused to start a shell/command

Authentication log (see session log for details):

Using username "admin".

Access denied.

Authentication failed.
