I know ssh public keys can include an option to only allow a specified
command to be executed using that key. Is there a way to get it to
allow a file transfer with scp but not allow a shell to be started using
that key? I do want to allow shells using a different key.
Quick and incomplete answer:
It's not the keys that have such options, it's a question of server
configuration that determines what capabilities are granted to a user
(authenticated by eg, matching a certain public key).
The subject matter to search on, I think, is
ssh "per account server configuration"
Your question might be re-posed as involving:
How to provide scp only access via per-account server configuration?
which, in fact, seems to trigger some google hits (that I haven't
followed <heh>).

Thanks for the info.
BTW, the ssh keys do provide some control. See man sshd, go to the
section titled AUTHORIZED_KEYS FILE FORMAT, then the following section
about options.
