Micheal Mac Donnacha — Tue, 31 Aug 2021 20:06:31 +0000

A walkthrough for Overthewire.org Bandit Level 3 -> 4

Level Goal

The password for the next level is stored in a hidden file in the inhere directory.

Walkthrough

username: bandit3

ssh bandit3@bandit.labs.overthewire.org -p 2220

Change directory into inhere, running ls command will show no files.

bandit3@bandit:~$ ls
inhere
bandit3@bandit:~$ cd inhere/
bandit3@bandit:~/inhere$ ls

Running ls -a will let us see all files including hidden files.

-a for all files (do not ignore entries starting with .)

We can then see a file named .hidden.

The you can print to screen using cat command.

bandit3@bandit:~/inhere$ ls -a
.  ..  .hidden
bandit3@bandit:~/inhere$ cat ./.hidden

Overthewire.org Bandit Level 2 -> 3

Description
A walkthrough for Bandit Level 2 → Level 3

Level Goal

The password for the next level is stored in a file called spaces in this filename located in the home directory

Walkthrough

username: bandit2

ssh bandit2@bandit.labs.overthewire.org -p 2220

This time there is a file with spaces in the name.

bandit2@bandit:~$ ls 
spaces in this filename

Running cat spaces in the filename will cause errors as it will think each word in spaces in the filename is its own separate file.

bandit2@bandit:~$ cat spaces in this filename
cat: spaces: No such file or directory 
cat: in: No such file or directory 
cat: this: No such file or directory
cat: filename: No such file or directory

Printing the contents of the file can be done 2 ways.

One using \ before each space to indicate to the terminal that the filename continues and the other is surrounding the file name with quotes ' or ".

bandit2@bandit:~$ cat 'spaces in this filename'
UmHadQ##########################
bandit2@bandit:~$ cat spaces\ in\ this\ filename
UmHadQ##########################

Overthewire.org Bandit Level 1 -> 2

This is the second in a series that will show how I solve the overthewire.org Bandit puzzles as I am completing them.

Bandit Level 1 → Level 2

Level Goal

The password for the next level is stored in a file called - located in the home directory

Walkthrough

This level similar to the first one is to just read the contents of a file to get the password. Login using the password obtained from the first level.

~$ ssh bandit1@bandit.labs.overthewire.org -p 2220
bandit0@bandit.labs.overthewire.org's password:

Once logged in I found a file named - . Running the command 'cat -' does not work as the cat command thinks your entering an option rather then the file name being '-'.
To read the file '-' I entered the the path to the file.

bandit1@bandit:~$ ls
-
bandit0@bandit:~$ cat ./-

The output from the cat ./- command is the password for the next level.
That's the second level completed.

Overthewire.org Bandit Level 0 -> 1

This is the first in a series that will show how I solve the overthewire.org Bandit puzzles as I am completing them and learning how to better navigate and use linux terminal.

Bandit level 0 -> level 1

Bandit Level 0 → Level 1

Level Goal

The password for the next level is stored in a file called readme located in the home directory. Use this password to log into bandit1 using SSH. Whenever you find a password for a level, use SSH (on port 2220) to log into that level and continue the game.
Walkthrough

This level is simple enough just login to the server using given username and password.

~$ ssh bandit0@bandit.labs.overthewire.org -p 2220
bandit0@bandit.labs.overthewire.org's password: bandit0

Once logged in I only needed to read the contents of the readme file.

bandit0@bandit:~$ ls
readmebandit0@bandit:~$ cat readme

The output from the cat readme command is the password for the next level.

First level is simple enough all that is needed is to read a file.
