Folks: these tools should only be used on networks that you own or have explicit consent to be on. “hacking” networks can land you in some very unpleasant places controlled by very scary people. I’ve been to countries where the Law Enforcement folks have told me some cautionary tales

This course was designed to provide information on how to use the command line environment in a Unix/Linux system to accomplish tasks such as imaging, data acquisition, and archiving.  This course covers the basics of Unix/Linux commands that allow users to view and edit text files, obtain hardware and system information, partitioning and formatting, process related commands, manipulating disks and partitions, imaging, archiving, logical acquisition, live system response, and basic networking.

This would be beneficial for folks who are interested in digital forensics, incidence response, system administration, ethical hacking, or just plain linux.  his course covers material for beginners as well as for advanced users. This course would also be helpful if you are considering taking the CompTIA Linux+ certification test.

Im just starting with networking. Have a web app in production (cloudflare + digital ocean VPS). at digital ocean, I have to ssh into my vps with ip say "xx.xx.xx.xx" but when I ping domain name from terminal I see entirely different ip. I have a lease for static IP (even though I probably dont need it), and IP visible in ping command output is not static, nor xx.xx.xx.xx for my VPS. How/why?
