Book: SSH Mastery
* SSH Mastery by Michael W. Lucas
I have a confession to make: I'm a terrible techie. I used to be a pretty good sysadmin a decade ago, but then I ended up in management and spent all my time on the business side of my company instead of the technical side. So when it comes to software and Best Practices, I'm well behind the times. That's probably why my current sysadmin recommended I read 'SSH Mastery'. Lucas is excellent at explaining not just how to do something but why you'd want to, and why you shouldn't do some things you might be tempted to do. Moreover, the tone strikes the right balance between "not patronizing" but also "not so technical you can't follow it without advanced knowledge of the subject". All of the technical details are there, and none of the technobabble. After reading 'SSH Mastery', not only was I able to successfully create and upload a key to our servers, but I understand why it's important and why I should have done it the first time my sysadmin asked me to.
