How to install Packetbeat on OpenBSD

Packetbeat is a lightweight shipper that monitors network traffic and sends it to the Elasticsearch or Logstash for indexing. In this tutorial, we will go through the process of installing Packetbeat on OpenBSD.

Prerequisites

Before we begin, ensure that your OpenBSD system is up to date by running the following commands:

$ sudo pkg_add -Uu

Step 1: Download Packetbeat

Download the latest version of Packetbeat from here using the curl command:

$ sudo curl -L -O https://artifacts.elastic.co/downloads/beats/packetbeat/packetbeat-7.15.1-openbsd-amd64.tar.gz

Step 2: Extract Packetbeat

Extract the downloaded Packetbeat file by running the following command:

$ sudo tar xzvf packetbeat-7.15.1-openbsd-amd64.tar.gz

Step 3: Configure Packetbeat

Next, navigate into the extracted Packetbeat directory and open the packetbeat.yml file with a text editor of your choice:

$ cd packetbeat-7.15.1-openbsd-amd64
$ sudo vi packetbeat.yml

Update the configuration settings as required. For example, you can uncomment the Elasticsearch output section and specify the Elasticsearch instance IP address and port number.

output.elasticsearch:
  hosts: ["http://localhost:9200"]

Save and close the file once you have made the necessary changes.

Step 4: Start Packetbeat

Start Packetbeat by running the following command:

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

This will start Packetbeat with the configuration settings file you modified in step 3.

Conclusion

You have successfully installed and configured Packetbeat on your OpenBSD system. You can now start monitoring your network traffic and sending the data to Elasticsearch or Logstash for indexing and analysis.
