I liked it a lot. I'm also pretty sure the IT stuff was legit. I'm not into the nuts and bolts stuff as much as I used to be, but I didn't hear anything in the show that I knew to be factually innaccurate. Which is amazing considering the amount of tech discussed.
Same here. Even some of the stuff as I pointed out to my wife, when he was saying in the narration that he would make it so that only he could access it, he started typing chmod -R, which at least is a real "unix" command l ine to recursively change the right of a file/folder. So yeah, pretty cool. I mean I would have been more impressed if he was using what looked like a regular terminal client like PuTTY or something, but I can live with what I saw.
