Use ssh with tar to move a directory of files between two machines as an alternative to scp:
tar -cvf - images/dogs | ssh jhawkins@collie.stanford.edu '(cd new_images; tar -xf -)'
scp copies files between hosts on a network. It uses ssh for data transfer, and uses the same authentication and provides the same security as ssh.

scp dogs.gif jhawkins@collie.stanford.edu:
