I will have to do many security training sessions soon at work and in a high school near where I live. I would like to record myself working on my computer. For example, record how I scan a network using nmap. You know, the kind of videos we get from Offensive Security and the like.
I have seen many on the internet. I don't mind paying a few dollars for a good one, but the best things in life are free! ;)
I run Ubuntu 10.04 amd64 and Backtrack 4 at home. I also want to have the option of recording my voice at the same time.
So what software would you recommend me to use?
