1. Challenge

   Establish a Secure Shell Connection Between Two SUSE Linux Enterprise Servers

   1. Use the ssh command and lab-specific system information to establish an SSH client session between your main lab system and a second lab system.
   2. Run commands on the remote system just as if you were on the console.
   3. Disconnect and run ssh commands in "hands-off" mode on the second system without actually creating a shell session, just dropping the command off and getting output on your first system.

2. Challenge

   Send and Receive Files and Directories Between Two SUSE Linux Enterprise Servers via `scp` and `sftp`

   1. Use the scp command to send and receive files between two servers, either pushing from the main system to the secondary, or being signed on the secondary and pulling the files to that system.
   2. Use the sftp command to establish a secure FTP session between the two systems and both send and receive files and directories between the systems, along with some interesting options.
3. Challenge

   Automate the Keyscanning of Other Hosts, Reporting Any Mismatches

   1. View your system's known_hosts initial state, then keyscan another system, and redirect that information to a master file for future reference.
   2. Connect to the remote system via SSH and view the changes that occur in your known_hosts file locally.
   3. Build an automated keyscanning setup that will scan a list of hosts for the proper key information, sort and make unique that info, and compare it against the known good master list, reporting any mismatches.
