Darren, thanks for the reply. I'm too new at this; I'm not
understanding what you are saying. How can I make sure none of the
.profile or .login junk is echoed on scp connections?

If I log in with putty I get a fairly normal looking login:

login as: USER
Sent username "USER"
USER@server.tld's password: (I enter it)

( then a "welcome" message is displayed - fairly large )

The putty event log looks fairly boring as it works its way to Session

If I use scp -v it all looks fairly boring until here:

debug1: Entering interactive session.
debug1: ssh_session2_setup: id 0
debug1: Sending command: scp -v -f somefile
debug1: channel request 0: exec
debug1: channel 0: open confirm rwindow 0 rmax 32768
mesg: ttyname: Operation not supported
protocol error: unexpected <newline>

If I pscp -v I get:

c:\blah> pscp -v USER@server.tld:somefile somefile.txt

Thanks for your help. Any ideas what I can do to track this down.
The odd part is WinSCP works.
