ftp://sunsite.unc.edu/pub/Linux/docs/linux-doc-project/network-guide/nag-1.0.ascii.tar.gz
The documentation that follows each software package will normally give you all the detailed information you need, if not always the overview. The man-pages will be the first place to look. Try for instance:
man pppd
You will also find some documentation about certain programs in the "/usr/doc" tree, although this is not always well structured.
The following HOWTOs will be highly relevant:
