wargames

The "wargames" are not invoked as a standalone command. Instead, they are accessed remotely using the SSH client.

The general syntax for connecting to an OverTheWire wargame server is:

ssh username@hostname -p port

For example, to connect to the first level of the Bandit wargame:

ssh bandit0@bandit.labs.overthewire.org -p 2220

The specific username, hostname, and port vary for each wargame series and level, and are provided on the OverTheWire website.

The term "wargames" in the Linux context typically refers to the

OverTheWire Wargames, a series of online, interactive security challenges designed to teach various aspects of computer security in a practical, hands-on manner.

These wargames are not a single Linux command you execute locally, but rather a set of remote servers accessible via SSH. Each wargame series, such as Bandit, Natas, Leviathan, or Krypton, focuses on different security disciplines, ranging from basic command-line usage and file permissions to web exploitation, cryptography, and binary exploitation.

Participants connect to a dedicated server for each game, solve a challenge (often finding a "flag" or password), and use that solution to log in to the next, more difficult level. This progressive learning approach makes them an excellent resource for beginners and seasoned security enthusiasts alike to develop and hone their skills in a safe, controlled environment.

Requires Internet Connection: Users need a stable internet connection to access the remote OverTheWire servers.

Educational Challenges: These are not standard commands but interactive puzzles requiring active problem-solving, research, and critical thinking.

Basic Linux Familiarity: A foundational understanding of the Linux command line is highly beneficial for navigating the challenges.

User Responsibility: While the environment is safe, users are encouraged to understand the implications of commands they execute, especially when dealing with unknown binaries on the game servers.

The "wargames" are not software installed and run on your local machine. They are remote environments hosted on dedicated servers, accessed exclusively via the Secure Shell (SSH) protocol. Each game presents a unique username, hostname, and port for connection.

The core purpose of the OverTheWire wargames is practical skill development. By solving successive levels, players learn about common vulnerabilities, security tools, Linux concepts, programming, and various hacking techniques in a legal and ethical manner.

Some of the most popular wargame series include Bandit (beginner-friendly Linux fundamentals), Natas (web application security), Leviathan (advanced network exploitation), and Krypton (cryptography). Each series offers a distinct learning path.

The OverTheWire Wargames project was initiated by the OverTheWire community as a platform to foster practical computer security skills. Starting with fundamental challenges, the series has grown significantly, becoming a widely recognized and respected resource in the cybersecurity community. Its development is community-driven, with contributions to new challenges and maintenance ensuring its continued relevance and educational value. The focus has always been on providing a hands-on learning experience that complements theoretical knowledge.
