This is a very good tutorial.I'm not lost and it's very well explained.Every command has explanation which is a good point.
My Suggestions :

• Maybe you can add your tutorial is made for linux/bash ? (apt-get)
• Maybe add a command to find server IP ?
• Maybe you can make the curriculum shorter (I don't know how, but it's very long ^^)

I saw you're a regular utopian author. It's very good and i want to see the next part !
Your tutorials are originals, and usefuls. This give more details than another tutorials.
You give somme screenshot and I think images are evry important in a post. So if you can add more images, do it !
