Hello all!

I have run into a problem with WinSCP 3.7.5 beta.

When I try to login to one particular server I get the error "Server refused to start a shell/command".

Using version 3.7.4 I'm able to login without any problems.

I am using the Norton interface

The remote system is a FreeBSD 4.3 box.

Thanks for any help with this!

Here are the debug logs:

SCP fallback is broken in WinSCP 3.7.5. You need to request SCP protocol explicitly on login dialog.

Is there a way to set the SCP protocol in a script file?

"open scp://session". See "help open".
