So the index number, or inode, is a number that is unique to a file in the Unix filesystem. It is an identifying number the OS will use when storing and retrieving the data. Data has two pieces to it - the metadata (permissions, file size, etc) along with the actual data itself.

You can find the inode of a particular file by using either of the below commands:

ls -i /home/mav3n/user.txt or stat /home/mav3n/user.txt

Hi!
I used the two commands to get the number, and I got to the same number, the problem is that when trying to answer the question it tells me that the answer is wrong … what could be happening?.

Edit:
I check the number of the sudoers in a target machine

Chances are high that it has a different index number on each different machine.

First - Be sure you are shelled into the target machine.
ssh htb-student@[target ip address]

Enter password - was given to you

So, lets take the long but simple path so you can see where you are going.

Step 1.
change directory to etc
cd /etc

Step 2.
list directory contents of etc
ls

Step 3.
You will see a long list of files. Find ‘sudoers’ so you know you are in the right place.

Step 4
ls -i and find the number next to sudoers.

Thats it. A Simple way
cd /etc
ls -i

And no, HTB didnt talk about the -i anywhere that I could see.

Happy Hunting

the only thing you need to do is use the command ls -i /etc/sudoers

Hi guys, I’ve got an issue

On the same question, i’ve tried both

ls -i /etc/sudoers

stat /etc/sudoers

The result is

Inode: 964110

but it don’t accept the answer! Also tried to restart the machine, but it doesn’t resolve the problem

How can I do? Is a HTB bug?

EDIT: solved accessing via ssh, it gave me another index number, wich was the right answer

stat/etc
stat /etc/sudoers
