Hi folks - having come from the world of microsoft, I've decided that it's finally time to get some serious knowledge about system administration in a *nix environment. I've installed Red Hat 9, and I have user-level understanding of bash, but that's about where my experience drops off.

Can anyone recommend any books which provide a solid basic understanding of *nix administration? Like I said, I'm not illiterate, I just want to learn about stuff like shell scripting, network configuration, file system management, security, kernel configuration, etc.
