Unfortunately, ufw doesn't have a safety net. However, I did keep a valid ssh connection in a separate window to ensure I could still login after I enabled ufw. That's still a dangerous way but my fallback is my server is with a company who can assist in a reboot and ssh access again if necessary. Alexander's idea is a good one, and I really should have taken his advice. However, all worked out well, fortunately. Thanks, Joe. -Tom
