OverTheWire Narnia Level 0 tutorial!!
Published on 17 Aug 2023
Login
Log in as narnia0.
ssh narnia0@narnia.labs.overthewire.org -p 2226
# password: narnia0
Why? Each Narnia level is a separate UNIX user. To solve Level 0 you must be the
narnia0user.
Task
Log into the game using SSH. Your goal for this first level is simply to connect to the remote machine successfully.
A little bit of Theory
- SSH (Secure Shell Protocol) lets you connect securely to a remote machine over an encrypted channel.
-
The typical syntax is:
ssh <username>@<server> -p <port>Here,
narnia0is the username,narnia.labs.overthewire.orgis the host, and-p 2226uses the custom port 2226 instead of the default 22. - On Windows you can use WSL or PuTTY; on Linux/macOS just use the built-in Terminal.
- After a successful login, you land in the user’s home directory (shown by
~in the prompt).

Solution
- Open terminal and run:
ssh narnia0@narnia.labs.overthewire.org -p 2226
- Enter the given password:
narnia0
- Boom 🎉 you’re inside as narnia0.
At this point nothing else to solve — just confirm you can connect. The real fun starts at Level 0 → 1.
Password for Next Level
(You don’t need to find it here — OTW provides it: narnia0)
That’s it for Level 0! 🎉 It’s purely a login test, but from here we’ll start digging into actual binaries.
Thanks for reading!
Until next time — Otsumachi!! 💖☄️✨
