2.1 command 404

Hi @htian,

Please pay attention to the note in the pdf, below the command, which warns about possible copy paste issues. Check the pasted command to the one in the pdf to ensure the pasted one is the same as the one in the pdf (in your case, it isn't). If you still have issues you can always download the files following instructions in the introductory chapter.

Also, for security best practice purposes, you should never post credentials in a public forum.
