How is this article even possible? Ofcourse you use google instead of man pages.
Lets say I install a new distro, I want to set up a firewall, routing/nat/forwarding (or whatever you kids call it these days), install my specific hardware and get a weird graphic card working properly in X.
What man page do I read? The manpage for "firewall", "internet connection sharing", "xconfigurator"? Nope. I google.
Seriously, man-pages are all good and perky for the nittygritty, but finding a complete solution for the most common tasks are NOT a option. And besides, how do I "man iptables" if the package isnt even installed.
Any new user to Linux would be completely and utterly stunned by the information contained with the iptables package. I cant even make any sense out of it except for the most basic commands after 10 years (not working as a administrator, praise the lord, though).
