SSH Tricks. Including how to wield SCP (secure file copy), how to use SSH without passwords by using the builtin keygen for specific MAC addresses (while noting that it is something of a security hole), remote execution, X11 forwarding (running graphical Linux applications remotely), and mounting a remote folder with SSHFS as an alternative to tunneling SAMBA mounts.
Quite useful, but SirDiggalot (from Digg.com) mentioned that perhaps the best way to get an archive from a remote machine that doesn’t have the resources (e.g., hard drive space) to make a complete tar backup is neglected:
cd /source/dir
tar -cf - . | ssh user@remote "(cd /destination/dir && tar -xpf -)“
Linux From Scratch. For the hardcore only: build your own Linux system, literally from the lowest level up. This isn’t like compiling your own distribution, though: this is like baking a cake by grinding your own flour. It might be the best cake you’ve ever eaten, and you’ll know exactly how to do it, but if you don’t have the stamina of an ultramarathoner and the patience of a tortoise, I can’t imagine being able to recommend this approach.
LearnLINUX: On the other hand, I can heartily recommend this for the novice! This is like a whole class in Linux, for free, online. Everything from Linux history to system administration and shell scripting. Bookmarked!
