Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Learning the terminal. Found this nice android app: "Linux Command Library"

It lists a number of man pages and examples.

I found this one:

block known dirty hosts from accessing your machine

wget -qO - http://infiltrated.net/blacklisted|awk '!/#|[a-z]/&&/./{print "iptables -A INPUT -s "$1" -j DROP"}'

I figured that domain was a list of spam sites and such.

Googled it. Found nothing mentioning it. Went to the domain and it was blocked by my ad blocker.

Anyone know of it?

I think an ever growing list isn't the best either. Probably makes more sense to utilise fail2ban which will manage your firewall rules appropriately.
