SSH Mastery

I highly recommend Michael W Lucas's SSH Mastery. Despite having acquired it before Sudo Mastery, I didn't read it until after. Actually, after having read Sudo Mastery, I was impressed enough with it that I went and dug out my copy of SSH Mastery and started reading. Again, I was sufficiently impressed with it and have since recommended both to numerous colleagues.

So, do your self a favor and had over to Tilted Windmill Press and pick up a copy of SSH Mastery and give it a read.
