About

what_it_isAn SSH wargame. You connect to a real Linux machine, find a hidden password, and use it to log in as the next user. Repeat until done.
how_it_worksSSH in as level0 with password level0. Each level has a clue that leads to the next level's password. Find it, move on.
who_its_forPeople learning Linux, command-line navigation, and basic security concepts. No prior experience required — just curiosity and a terminal.
shared_serverEveryone connects to the same machine. Passwords are randomised on every server restart so answers can't be shared. Your actions don't affect other players' files.
no_accountNo registration, no tracking. Just SSH in and start playing.

How to connect

You need an SSH client. On Linux and macOS it's built in. On Windows, use PowerShell, Windows Terminal, or PuTTY.

ssh level0@217.154.8.251 -p 30022

The starting password is level0. Everything after that you find yourself.
