Secure Shell - Working with SSH Keys

In this lab, you'll configure and create SSH keys that enable passwordless SSH between 2 servers. Then you'll test the connection. The scenario for the lab is as follows: The IT manager at Eucalyptus and Lavender Inc. has asked you to install and configure a new SSH server on Server1. In addition, set up a key pair for the "cloud_user" user account to transfer files between Server1 and Server2 without prompting for a password. Good luck!
