Fortress is a Linux based Box on TryHackMe. Due to unintended issues with the configuration of the box the difficulty was decreased from HARD to MEDIUM, see Unintended Ways for some methods to get root on the box.
The description of the box suggests to add two hosts:
10.10.222.252 fortress
10.10.222.252 temple.fortress
