 Duo Mobile push:

If you usually get a two-factor push to your phone, just hit enter after entering your username and password, then complete authentication by approving the push on your device.

 Phone Call:

Without hitting enter after typing in your username and password, in the password text box, append a comma (,) to the end of your password, then append phone as shown in the screenshot below:

You should get a phone call on your main phone # associated with your two factor account. Answer this call and hit # to approve access.

 Duo Passcode

02 Why do we need a Text Editor?

02.01: Using the Terminal/Command-Line

• We have a non-GUI/non-Windows environment.

• Unable to start a GUI/Window text-editor type application.

• We’re using the command-line.

02.02: Available Text Editors

• Just one of several available command-line based text editors.

  • ex: EXtended

  • emacs:

  • vi: 

  • vim: Vi Improved: What are some of the improvements of Vim over Vi?

  • nano: 

  • and others...

02.03: Why vim?

• Considerations:

  • What’s available on the system you’re using?

  • Can you install other editors?

  • What is your personal choice?

  • Note: On our MedicineBow cluster, vi is an alias for vim – meaning if you start vi, vim will start.
