# This assumes three things:
#
# 1) That you have an SSH server running on your local machine,
# 2) That the USER environment variable is set to your user name, and
# 3) That you have public and private keys conigured so that you can log into
# your machine via SSH without being prompted for a password.
#
# If #2 or #3 are not true, you can add your user-name and password as the
# second and third parameters (respectively) to Net::SSH.start.

# Note: two things here,
#
# 1) open_channel does not immediately invoke the associated block. It only
# calls the block after the server has confirmed that the channel is valid.
# 2) channel.exec does not block--it just sends the request to the server and
# returns.
#
# For these two reasons, you MUST call session.loop, so that packets get
# processed and dispatched to the appropriate channel for handling.
