This is informative, and I'll use it because my 12 machine home network
is all ipv4, but its for only one option. Doing "sysctl -a|wc -l" gets
me 829 such options to set. So where can I find the real, complete,
list of options AND the effect of changing each one?
googling around may accidentally get you this info for 2 or 3 such lines
you can put in your /etc/sysctl.conf, but where is the full, wonderfully
verbose list that explains them all?
