AWWWW... man, I thought that was going to do it:

-bash-3.00$ scp classified at classified:system:running-config xxxxxxx-confg
The authenticity of host 'classified' can't be established.
RSA key fingerprint is 'classified'
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'classified' (RSA) to the list of known hosts.
Privilege denied.
channel_lookup: 0: bad id: channel free
client_input_channel_req: channel 0: unknown channel

now time to look up the errors.

Good ideas, all!  Keep 'em coming.
