Info on /proc/sys/net/ipv4

[Les]

Hi, everyone,
	I am having difficulty with some websites as well, particularly one
that uses frames and multiple hosts for Java and Javascript, including
links to 3rd party content.  I have followed many of the hints, but now
I am ready to attempt some serious (read that as actual)
troubleshooting.  To begin that process, I would like to know where to
go for information regarding the /proc/sys/net/ipv4 files, how to
configure them what they do, and what options there are.  Can anyone
provide me a link to known reliable information, or recommend some
book(s)?

	I have looked at several books on firefox, and found them woefully
lacking in technical content, oriented mostly for windows users, so a
good reference for a firefox technical reference would be appreciated as
well, specifically one that some of you good admin types found helpful.

	I prefer books rather than on line.  I find that my glaucoma limits how
long I can read on the computer more than via books.

Thanks,
Les H
