This subchapter looks at netstat, a UNIX (and Linux) command.
netstat is used to symbolically displays the contents of various network-related data structures.
Type netstat to see the list of all sockets and server connections.
$ netstat
The main information for webserver administration is in the first few lines, so you can pipe to head:
$ netstat | head
Use the -r option to display the network routing addresses.
$ netstat -r
In June 2009, Ken Milberg named this command as one of the Top 50 universal UNIX commands at this web page Top 50 Universal INIX commands. Note that this web page requires agreeing to be spammed before you can read it.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

Work on this project is very slow because I am homeless. I am available for work if someone can provide an indoor place to work in Costa Mesa, California, electricity, internet connections, a flat raised working surface (such as a table or desk), a sitting device (such as a chair or stool), and a fully functional reasonably modern used computer. I’m already homeless, so you don’t need to pay me (and I understand how much business people hate the minimum wage law). Just give me a chance to work.
