Get to know your Linux system - Lesson #4

In this fourth episode of “Get To Know Your Linux-System” we wanna examine the network capabilities of the system you are currently on.

And to be honest - this lesson is a tough one - if you aren’t the guy who configures networks every day.

Therefore I try to keep it as simple as possible …

What will you learn?

• examine the configuration the network-interfaces
• which ports are open?
• … and which processes are listening
• is there a local firewall in place?

Notes:

at 5:52 I talk about “IP version 5” - obviously it’s “IP version 4” ;-)
