Welcome to this step-by-step guide on setting up Hydra for brute force password cracking on Ubuntu. Hydra is a powerful tool that allows you to perform rapid password cracking using a variety of protocols. In this tutorial, we’ll walk you through the process of installing and using Hydra on an Ubuntu system.

Step 1: Installing Hydra

The first step in setting up Hydra on Ubuntu is to install the software. You can do this using the apt package manager with the following command:

    sudo apt-get install hydra

Step 2: Understanding Hydra’s Syntax

Before you can start using Hydra, it’s important to understand its syntax. The basic command structure is as follows:

    hydra [options] [server] [protocol] [user list] [password list]

Each part of this command has a specific purpose:

  • options: These are flags that modify the behavior of Hydra. For example, the -v flag enables verbose mode, which provides more detailed output.
  • server: This is the IP address or hostname of the target server.
  • protocol: This is the protocol to use for the attack, such as ftp, http, or ssh.
  • user list: This is a file containing a list of usernames to try.
  • password list: This is a file containing a list of passwords to try.

Step 3: Running a Brute Force Attack

Now that you’ve installed Hydra and understand its syntax, you’re ready to run a brute force attack. Here’s an example command:

    hydra -l user -P passlist.txt

This command tells Hydra to use the username ‘user’, the password list ‘passlist.txt’, and to attack the FTP server at


Congratulations! You’ve now set up Hydra on your Ubuntu system and are ready to start cracking passwords. Remember, this tool should only be used for legal, ethical hacking. Always get permission before testing on a system that isn’t yours. For more information on ethical hacking, check out the EC-Council’s guide.
