I never pass up an opportunity to recommend the Cyber Plumber's Handbook: https://github.com/opsdisk/the_cyber_plumbers_handbook
Goes over similar content as TFA, in perhaps a little more depth. Indispensable sysadmin knowledge.
Appreciate the mention wbadart!
Not mentioning the ssh -w option in that book should be a crime.
so good, I learn new things.
