Overall, very nice. There are just a few things I would change:
1) Emphasize disabling password-logins and possibly changing the port number (above 1024). SSH servers sitting on port 22 can get upwards of hundreds of attacks per hour!
2) You have “Scp ~/.ssh/dsa_key.pub student@192.168.50.14:~/.ssh/authorized_keys” in your Overview. Not only should scp be all lowercase (typo), but that only works for the FIRST public key you want to add. ssh has a VERY nice utility called “ssh-copy-id student@192.168.50.14” It is simpler and works for multiple users.
3) Show off some of the cool stuff you can do such as sftp and sshfs.
Minor typo in the overview sheet
“Scp ~/.ssh/dsa_key.pub student@192.168.50.14:~/.ssh/authorized_keys”
should be “scp” not “Scp”.
