TASK 1 - INTRODUCTION
Q1) Let's proceed! [ No Answer Needed ]
TASK 2 - Accessing Your Linux Machine Using SSH (Deploy)
Remember this :-
For this room, we will be logging in as "tryhackme", whose password is "tryhackme" without the quotation ("") marks. Let's use the IP address of the machine displayed in the card at the top of the room as the IP address and this user, to construct a command to log in to the remote machine using SSH. The command to do so is ssh and then the username of the account, @ the IP address of the machine.
Connect to the machine using ssh :- ssh tryhackme@10.10.xx.xx
Q1) I've logged into the Linux Fundamentals Part 2 machine using SSH! [ No Answer Needed ]

TASK 6 - COMMON DIRECTORIES
Remember this :-
Dir. Name
explanation
/etc
This root directory is one of the most important root directories on your system. The etc folder (short for etcetera) is a commonplace location to store system files that are used by your operating system.
/var
The "/var" directory, with "var" being short for variable data, is one of the main root folders found on a Linux install. This folder stores data that is frequently accessed or written by services or applications running on the system.
/root
Unlike the /home directory, the /root folder is actually the home for the "root" system user.
/tmp
This is a unique root directory found on a Linux install. Short for "temporary", the /tmp directory is volatile and is used to store data that is only needed to be accessed once or twice. Similar to the memory on your computer, once the computer is restarted, the contents of this folder are cleared out.
Q1) Read me! [ No Answer Needed ]
Q2) What is the directory path that would we expect logs to be stored in? [ /var/*** ]
Q3) What root directory is similar to how RAM on a computer works? [ /t** ] (hint :- Similar to the memory/RAM on your computer, once the computer is restarted, the contents of this folder are cleared out.)
Q4) Name the home directory of the root user [ /r*** ]
Q5) Now apply your learning and navigate through these directories on the deployed Linux machine. [ No Answer Needed ]
