  3. Confirm that the sshd daemon is up and running:
    # systemctl status sshd
  4. Open the SSH port 22 to allow incoming traffic:

    # firewall-cmd --reload
  5. Optionally, locate the SSH server man config file /etc/ssh/sshd_config and perform custom configuration.

    Every time you make any change to the /etc/ssh/sshd_config configuration file reload the sshd service to apply changes:
     # systemctl reload sshd
