Hi Dr. Craiger, is there any place I can get the proper order of these videos? You have a playlist of 30 videos, and I'm pretty sure this video should be the 1st one but its 18th and there are others that I can tell should have come 1st compared to others. They are great videos, very helpful, thank you for making them!
Bro! You're good! Thank you! I've learned more in 30+ minutes than i have in my "Sec+" training through DHS over the past 5 weeks.
Well done

This was tutorial was uploaded in 2014 and the solution still works in 2021.
nano doesn't use Ctrl-S - Save because Ctrl-s halts output in most terminal programs. The display would freeze. Ctrl-S is "XOFF", while Ctrl-Q is "XON". To unfreeze the display after an XOFF, type Ctrl-Q.
Sadly that FORWARD theme wasn't covered...
Fantastic - you have nailed it - a medium/advanced topic in laymans terms. It's not an easy feat. Thank you!
thanks
finally someone who knows what they are talking about and actually make a video that is worthwhile watching.
