Hi Jannis,

Subject: openssh public Key Athentication - with restrickted login shell

Hi,

I'd like too use scp to transfer data to a Linux box out of a perl script using public key authentication(with no 
passphrase:-( ).
As long as the used userid has a regular account on that server everything works fine.
But for higher security I'd like the user not to be able to login, so I gave him a "nologin shell" in the /etc/paswd. 
In this case its also inposible
to authenticate as before.
So I thought it should be a working but restricted "login shell", which is sufficient enough for that user complete the 
authentication and to do its scp file transfer, nothing else.
Any idea?

Thanks in advance

Jannis
