Working with SSH Servers on SUSE Linux Enterprise

In this lab, you'll look at the SSH client and server options that work together to make secure connections, including the `ssh_config` and `sshd_config` files. You'll view the file configurations and make some changes that ensure `root` users are not allowed to sign on via SSH. Additionally, you'll configure your user environment and a remote server to allow for password-less ssh connections between the two systems using `ssh-keygen`, the `ssh-agent`, and the `ssh-add` commands to enable your shell for such access.

Challenge

View and Modify the SSH Client and SSH Server Configurations to Allow Proper Access via SSH
1. View the /etc/ssh/ssh_config file and configure how the client system handles host keys.
2. View the /etc/ssh/sshd_config file and check the port that SSH uses, verify the Authentication section settings are set to policy, and then create a local user SSH client config file to change how that user gets prompted for keys from hosts they attempt to log in to.
Challenge

Configure Password-less Connections Between Two systems via SSH
1. Generate a key pair for use in the lab.
2. Upload the client system's public key to the remote system.
3. Sign in via SSH to verify things work properly.
4. Add your credentials via the ssh-add command to the ssh-agent, and then connect to the remote system without having to authenticate each time with a password.
