I agree also.  I'm going along the same self-taught path using CentOS
5.5, lurking and absorbing all of the cool stuff that happens on this
mailing list.

Currently using this great manual:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/pdf/Security-Enhanced_Linux/Red_Hat_Enterprise_Linux-6-Security-Enhanced_Linux-en-US.pdf

I think my next thing to learn is httpd configuration.
And then maybe a little perl (I already know python and regex's).

Any other important topics to know?
