== Preparing the rootfs Image: Setting a Message of the Day ==
Edit the Message of the Day file so that you can be sure that you've connected to the right plug later in this workshop.
# Edit the file <code>/media/*/etc/motd</code>
# Add a greeting of your own choice. For example: <code>Welcome to Chris & Diane's GuruPlug!</code>
# Save the file.
== Try it! ==
To connect to your plug over the network, you'll need to connect to the computer managing the GuruPlug cluster, which is named "HongKong".
# Connect to HongKong: <code>ssh -XC ''nameOfYourPlug''@hongkong.proximity.on.ca</code> -- for example, if your GuruPlug is <code>cdot-guru-2-3</code>, then connect with <code>ssh -XC cdot-guru-2-3@hongkong</code> (password is "fsoss10")# Connect to your plug fron HongKong: <code>ssh root@''nameOfYourPlug''</code>(password is "fedoraarm")# Check the message of the day (printed after you log in) to be sure you have connected to the right GuruPlug.
