Step 1: Install Dependencies

Step 2: Download Packetbeat

1. Visit the Packetbeat website at https://www.elastic.co/products/beats.

2. Click on the download button and select the appropriate version of Packetbeat for your platform. For this tutorial, we will be downloading the latest version of Packetbeat for Linux:

   wget https://artifacts.elastic.co/downloads/beats/packetbeat/packetbeat-7.15.1-linux-x86_64.tar.gz
   

3. Extract the downloaded file using the following command:

   tar -zxvf packetbeat-7.15.1-linux-x86_64.tar.gz
   

4. Move the extracted directory to the "/opt" directory:

   sudo mv packetbeat-7.15.1-linux-x86_64 /opt/packetbeat
   

Step 3: Configure Packetbeat

1. Navigate to the "/opt/packetbeat" directory:

   cd /opt/packetbeat
   

2. Copy the example configuration file to the current directory:

   cp packetbeat.yml.example packetbeat.yml
   

3. Open the "packetbeat.yml" configuration file using your preferred text editor. In this tutorial, we will use the nano editor:

   sudo nano packetbeat.yml
   

4. Find the "output.elasticsearch" section and uncomment it to configure Packetbeat to send data to Elasticsearch. Then, replace the default values with your Elasticsearch host and port:

   #output.elasticsearch:
   #  hosts: ["localhost:9200"]
   #  username: "elastic"
   #  password: "changeme"
   

   For example:

   output.elasticsearch:

Step 4: Run Packetbeat

1. To start Packetbeat in the foreground, run the following command:

   sudo ./packetbeat -e
   

2. If you want to run Packetbeat in the background, use the following command:

   sudo nohup ./packetbeat -e &
   

   Note: The "&" symbol at the end of the command tells the system to run the process in the background.

3. Wait for Packetbeat to start and begin capturing network traffic.
