Podcast Experiment: Technology explained ...

With this podcast I start a little experiment:

Can technology be explained by words only?

Let's try this out ...

[#5] 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?

In this third step of “Get To Know Your Linux-System”, we wanna examine the diskspace a system uses.

And disk space - this is the number one resource if it comes to unplanned outages.

Let me talk in this lesson about

  • how to get insights into the used disk-space

… and as much important like this …

  • how to examine where - in which directories and by which files - all the disk space is consumed.

In this second step of “Get To Know Your Linux-System” you will learn more about the CPU- and memory-load of your system.

What you will get

  • We will have a look at the processes a system is currently busy with
  • You will see, how much memory a system has installed and how it is used
  • You will get the insight, if your system, is slowed down because of a memory-overload.

… and incidentally, I will show you, how you can pause a process and reactivate it later on.

[#2] Get to know your Linux system - Lesson #1

If you want to get to know your Linux-system - use as a starting-point the command “with the probably most useful information per keystroke” 🙂

This command gives you a great first impression about the system you’re on.

Additionally you will learn

  • about the time of your system and how to find out the timezone it is configured with
  • how to find out, if your system is currently overloaded or not
  • how to find out, if there are currently other users working on the system.

” … how can I solve the problem with these special-characters? The shell always gets me wrong …”

The fast and simple answer to this is: You have to quote!

… and you have to to it the right way.

But let’s start from the beginning …
