Limiting a user to scp and not ssh

[George Toft]

KLUDGE: I noticed that during the scp operation, with bash as the shell,
a new shell is not spawned.  If a user ssh's into the box, a new shell
is spawned.  Put "exit" in ~/.bash_profile - as soon as they log in,
they log out.

Hopefully, there is a better solution, but this one works.  Let us know
how you proceed.
