I am trying to connect to SSH server using WinSCP2. I am getting error message "Server refused to start a shell/command" after authentication.

What could be the problem?

Thanks

You should better check the server's log to see why it refuses to start the SFTP server.

Hi

I'm having the same problem here now. Thing is I downloaded winscp 3.7.6 a while ago and tested it against some embedded linux systems we hare building. All worked well.
Today I tried again and got the "refused to start a shell error". Perhaps something changed in our target systems but I can still scp from a linux box to them.
I suspect some windows 2000 update has got in the way here.

This is the error box text:

Authentication log (see session log for details):
Using username "root".

Server refused to start a shell/command

And this is the log file:
