Magnet Weekly CTF Challenge Week 7 Writeup

After two weeks of challenging questions, week 7's Magnet Weekly CTF challenge is much more relenting and gentle than before. Despite the challenge was created as a three-parter, all the answers could be found from one single file.

So this week's challenge questions are:

  1. What is the IP address of the HDFS primary node?
  2. Is the IP address on HDFS-Primary dynamically or statically assigned?
  3. What is the interface name for the primary HDFS node?

In order to locate the answers to these questions, the /etc/network/interfaces file from the HDFS primary node should be looked at:


And boom, all the answers could be found here! 

  1. What is the IP address of the HDFS primary node? (192.168.2.100)
  2. Is the IP address on HDFS-Primary dynamically or statically assigned? (static)
  3. What is the interface name for the primary HDFS node? (ens33)

Case closed for this week.

Following the 1st week of the Hexordia Weekly CTF Challenge 2024, we are now into week 2 of this CTF.
