How to Install Packetbeat on Void Linux

Packetbeat is a lightweight open-source data shipper that helps you monitor network traffic. In this tutorial, we will guide you on how to install Packetbeat on Void Linux.

Prerequisites

To follow along with this guide, you will need:

• A running instance of Void Linux.
• Superuser access (sudo command will work).
• A stable internet connection.

Step 1: Install Elasticsearch

Before starting the Packetbeat installation process, you will need to install Elasticsearch. Here is how to do this on Void Linux:

1. Open the terminal.

2. Run the following command to update the Void Linux package database:

   sudo xbps-install -S
   

3. Once the database is updated, run the following command to install Elasticsearch:

   sudo xbps-install elasticsearch
   

4. Elasticsearch should now be installed on your system.

Step 2: Install Packetbeat

Now that Elasticsearch is installed on your system, you can start the Packetbeat installation process:

1. Open the terminal.

2. Run the following command to update the Void Linux package database:

   sudo xbps-install -S
   

3. Once the database is updated, run the following command to install Packetbeat:

   sudo xbps-install packetbeat
   

4. If the installation is successful, Packetbeat will be installed on your system.

Step 3: Configure Packetbeat

Once Packetbeat is installed on your system, you need to configure it to start collecting data. Here's how to do that:

1. Navigate to the Packetbeat configuration directory:

   cd /etc/packetbeat/
   

2. Rename the example configuration file to packetbeat.yml:

   sudo mv packetbeat.yml.example packetbeat.yml
   

3. Open the configuration file:

   sudo nano packetbeat.yml
   

4. Configure Packetbeat to send data to Elasticsearch by adding the following lines to the output section of the configuration file:

   output.elasticsearch:
     hosts: ["localhost:9200"]
     index: "packetbeat-%{+yyyy.MM.dd}"
   

5. Save the configuration file and exit Nano.

Step 4: Start Packetbeat

After you have configured Packetbeat to send data to Elasticsearch, you can start it by following these steps:

1. Navigate to the Packetbeat installation directory:

   cd /usr/share/packetbeat/
   

2. Run the following command to start Packetbeat:

   sudo ./packetbeat -e -c /etc/packetbeat/packetbeat.yml
   

3. Packetbeat should now be running and sending data to Elasticsearch.

Conclusion

By following this tutorial, you have successfully installed and configured Packetbeat on Void Linux. Packetbeat will now be collecting network traffic data and sending it to Elasticsearch. You can use Kibana to visualize and analyze this data in real-time.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
