Looking for Unix help...

Okay... I'm out of work, and I need some stuff to study while I have some actual free time.

I've made my first obvious newbie mistake, and loaded Ubuntu server on my old desktop.

(Windows is the OS that has the bells and whistles and security holes baked into its servers; Unix uses minimal servers so that there are fewer security holes. In this case, I'm including "breakable things" as part of security.)

I knew better, really. I remember that there need be no difference between desktop and server Unix.

Anyway: I now have desktop Ubuntu running, and I've actually run a configure/make/make install on MySQL. Soon, I'll even verify that it works.... I'm going to dig into /etc/init* scripts (or directories) and inittab and try to figure my way through fstab and mnt.

I've gotten a tiny bit of right-feeling about the directory structure. I know to look for root-run binaries in /sbin, to look in /bin for certain binaries, and /usr/bin for certain other binaries. I learned /tmp and /var, and more. I successfully assimilated sudo and smirked when I realized I could sudo su; that last bit made me feel like the child-me picking a lock that protected the Oreos.

Next I need SSH and an SSH client so I don't have to use the awful KVM that I'm stuck with.

After that... well, does anyone have any pointers to some basic system and app monitoring and maintenance?
