# This script is a workaround for the key collision issue when loging into
# onos cli from both test-station and onos cells with identical user names.
# It copies both private and public keys of localhost (test-station) to
# all remote hosts specified in your cell.
# It also backs up the original keys of the remote hosts before
# overwriting them.
# Setting up passwordless login is recommended before running the script.
