This is a walkthrough of a Linux fundamentals Section(Service and Process Management) in HTB Academy. It is recommended that you do the module in HTB Academy to understand what is happening! (BTW IT’S FREE!)

In this section, we will use openvpn to connect to the HTB Academy network and then attempt the section. If you are unsure of how to connect to openvpn in HTB Academy, you can check this out:

Openvpn for Tryhackme or HTB

Now, let’s get on with the section Questions:

First, we have to ssh into the machine:

But this is not very efficient! We can easily make it a lot more efficient using grep! Look at what I did:

By simply using grep, we saved a lot of time very easily and solved the question with efficiency!
