Go to room

Power-up your Linux skills and get hands-on with some common utilities that you are likely to use day-to-day!

Task 1 - Introduction

  • Let's proceed!

No answer needed

Task 2 - Deploy Your Linux Machine

  • I've logged into the Linux Fundamentals Part 3 machine using SSH and have deployed the AttackBox successfully!

No answer needed

Task 3 - Terminal Text Editors

  • Create a file using Nano

No answer needed

  • Edit "task3" located in "tryhackme"'s home directory using Nano. What is the flag?

Task 4 - General/Useful Utilities

  • Ensure you are connected to the deployed instance (MACHINE_IP)

No answer needed

  • Now, use Python 3's "HTTPServer" module to start a web server in the home directory of the "tryhackme" user on the deployed instance.

No answer needed

  • Download the file http://MACHINE_IP:8000/.flag.txt onto the TryHackMe AttackBox

  • What are the contents?

THM{WGET_WEBSERVER}

  • Create and download files to further apply your learning -- see how you can read the documentation on Python3's "HTTPServer" module.

  • Use Ctrl + C to stop the Python3 HTTPServer module once you are finished.
