Detailed Guide on Installing Metasploit Framework (MSF) on Ubuntu

[miracle123456]

The Metasploit Framework (MSF) is one of the most powerful and widely-used tools for penetration testing and ethical hacking. It is used for developing and executing exploit code against remote target machines. In this guide, we will walk through the detailed process of installing Metasploit Framework on Ubuntu, one of the most popular Linux distributions used for security testing.

1. System Requirements​

Before installing Metasploit Framework, ensure that your system meets the following requirements:

• Operating System: Ubuntu 20.04 LTS or later (Ubuntu 22.04 is recommended)
• Memory: At least 4GB RAM (8GB or more is ideal for better performance)
• Disk Space: At least 10GB of free space for Metasploit and its dependencies
• Processor: x86_64 architecture (64-bit)

Metasploit is compatible with most versions of Ubuntu and should work without issue on modern versions of Ubuntu.

2. Preparing Your Ubuntu System​

Ensure your system is up to date before installing Metasploit. Open a terminal and run the following commands:

1. Update the package list:
   sudo apt update
2. Upgrade installed packages:
   sudo apt upgrade -y
3. Install essential dependencies: Some packages and dependencies might not be installed by default. Run the following command to install required libraries and utilities:
   sudo apt install -y curl gnupg2 build-essential libpq-dev libreadline-dev libsqlite3-dev libpcap-dev libxml2-dev libxslt1-dev liblzma-dev zlib1g-dev
4. Install and configure PostgreSQL: Metasploit requires PostgreSQL as its database backend. To install PostgreSQL, run:
   sudo apt install -y postgresql postgresql-contrib
   After installation, start and enable PostgreSQL to run automatically:
   sudo systemctl enable postgresql
   sudo systemctl start postgresql

3. Installing Metasploit Framework​

There are two primary methods to install Metasploit on Ubuntu: using the package manager or by cloning the GitHub repository and installing from source. We will cover both options.

3.1 Option 1: Installation via Package Manager​

Ubuntu provides a convenient package for Metasploit that can be installed using the APT package manager. This is a quick and straightforward method, but it might not always provide the latest version.

1. Install Metasploit from the official repository: First, add the necessary repository for Metasploit. Execute the following commands:
   curl https://raw.githubusercontent.com/rapid7/metasploit-framework/master/msfupdate | sudo bash
2. Install the Metasploit package: Once the repository is added, install Metasploit:
   sudo apt install metasploit-framework
3. Verify the installation: After installation, you can verify that Metasploit was installed successfully by running:
   msfconsole
   This should launch the Metasploit console.

3.2 Option 2: Installation via GitHub Source​

If you want the latest stable version or a custom build, you can install Metasploit from the GitHub repository.

1. Install Git: If you don’t have Git installed, first install it:
   sudo apt install git
2. Clone the Metasploit repository: Clone the Metasploit framework from GitHub into a directory of your choice:
   git clone https://github.com/rapid7/metasploit-framework.git
3. Navigate to the Metasploit directory: Change into the Metasploit directory:
   cd metasploit-framework
4. Install dependencies: Install the required gems (dependencies) for Metasploit:
   sudo apt install -y ruby-full
   sudo apt install -y libpcap-dev
   sudo apt install -y libsqlite3-dev
   Then, install the necessary Ruby gems:
   bundle install
5. Configure the database: Metasploit uses PostgreSQL as its backend database. If you have not set up PostgreSQL, do so now.
   • Set up the PostgreSQL database user for Metasploit:
     sudo msfdb init
   • This command will initialize the database and configure the environment to work with Metasploit.
6. Run Metasploit: After the installation is complete, you can run Metasploit by executing:
   ./msfconsole

4. Post-Installation Setup​

4.1 Setting Up PostgreSQL Database​

After installation, you will need to initialize the database for Metasploit to work. You can do this by running:
msfdb init
This command sets up PostgreSQL, creates a Metasploit database, and makes sure that Metasploit is configured to use it.

4.2 Starting and Stopping the Database​

To manually start and stop PostgreSQL, use the following commands:

• Start PostgreSQL:
  sudo systemctl start postgresql
• Stop PostgreSQL:
  sudo systemctl stop postgresql

---

5. Running Metasploit Framework​

Once Metasploit is installed, you can launch the Metasploit console by typing the following command:
msfconsole
This will load the Metasploit Framework and you should see the msf> prompt where you can start executing commands.

Basic Commands​

• Search for exploits:
  search type:exploit name:<exploit_name>
• Use an exploit:
  use exploit/windows/smb/ms08_067_netapi
• Show available options for the exploit:
  show options
• Set payload:
  set payload windows/meterpreter/reverse_tcp
• Launch the exploit:
  exploit

6. Updating Metasploit​

Metasploit is regularly updated to add new exploits and features. To ensure you are using the latest version, you should update Metasploit periodically.

1. To update Metasploit: If you installed Metasploit from the package manager, run:
   sudo apt update && sudo apt upgrade metasploit-framework
   If you installed Metasploit from GitHub, navigate to the Metasploit directory and run:
   git pull
   bundle install
2. Update the database: Update the database to ensure you have the latest version:
   msfdb update

---

7. Troubleshooting​

Common Issues and Solutions​

• PostgreSQL not starting: If PostgreSQL doesn’t start, ensure it’s enabled and running. You can check its status with:
  sudo systemctl status postgresql
  If it’s not running, try restarting it:
  sudo systemctl restart postgresql
• Missing dependencies: If Metasploit gives an error about missing dependencies, try installing the required libraries:
  sudo apt install -y libpq-dev libreadline-dev libsqlite3-dev
• Permission issues: If you encounter permission errors, ensure that you are running commands with sudo where necessary.

8. Uninstalling Metasploit​

To uninstall Metasploit, follow the instructions depending on your installation method.

If installed via package manager:​

sudo apt remove --purge metasploit-framework

If installed from GitHub:​

1. Delete the Metasploit directory:
   rm -rf metasploit-framework
2. Optionally, remove PostgreSQL
   sudo apt remove --purge postgresql postgresql-contrib

---

With this guide, you should now have a fully functional Metasploit Framework setup on your Ubuntu system. You can begin using it for penetration testing and exploring the world of ethical hacking. Make sure to keep Metasploit updated and regularly check for the latest exploits and improvements.
