Packetbeat is a lightweight network packet analyzer that monitors network traffic and sends data to Elasticsearch or Logstash for indexing and analysis. In this tutorial, we will walk you through the steps to install Packetbeat on OpenSUSE latest.
Before we begin, you need to have the following:
Follow the steps below to install Packetbeat on OpenSUSE latest.
The first step is to update the package repository and the system.
sudo zypper update
Packetbeat can be downloaded from the Elastic.co website. Open your web browser, go to https://www.elastic.co/downloads/beats/packetbeat, and download the latest release for Linux.
Alternatively, you can download it using the curl command:
curl -L -O https://artifacts.elastic.co/downloads/beats/packetbeat/packetbeat-7.12.0-linux-x86_64.tar.gz
After downloading the Packetbeat archive, extract it to a directory of your choice.
tar xzvf packetbeat-7.12.0-linux-x86_64.tar.gz
Then, navigate to the extracted directory.
cd packetbeat-7.12.0-linux-x86_64/
You can install Packetbeat either as a service or run it in the foreground.
To install Packetbeat as a service, run the following command:
sudo ./install.sh
When prompted, enter your root password to install Packetbeat.
To run Packetbeat in the foreground, use the following command:
./packetbeat -e
Now, let's configure Packetbeat to monitor network traffic and send data to Elasticsearch or Logstash.
Open the Packetbeat configuration file using your preferred text editor.
sudo nano /etc/packetbeat/packetbeat.yml
In the packetbeat.interfaces.device section, set the network interface to monitor. For example:
packetbeat.interfaces.device: eth0
In the output.elasticsearch section, configure the Elasticsearch server where Packetbeat should send data. For example:
output.elasticsearch:
hosts: ["http://localhost:9200"]
username: "elastic"
password: "changeme"
Alternatively, you can configure Packetbeat to send data to a Logstash server:
output.logstash:
hosts: ["localhost:5044"]
ssl.certificate_authorities: ["/etc/packetbeat/certs/logstash.crt"]
Save the changes and close the file.
If you installed Packetbeat as a service, start it using the following command:
sudo systemctl start packetbeat
If you are running Packetbeat in the foreground, press Ctrl+C to stop it, then start it again using:
./packetbeat -e
To verify that Packetbeat is running and sending data to Elasticsearch or Logstash, check the Packetbeat logs and indices.
View the Packetbeat logs:
sudo journalctl -u packetbeat -f
You can also run the following command to view the Packetbeat indices:
curl http://localhost:9200/_cat/indices?v
If everything is set up correctly, you should see Packetbeat sending network data to Elasticsearch or Logstash.
In this tutorial, we have shown you how to install and configure Packetbeat on OpenSUSE Latest. Packetbeat is now ready to monitor your network traffic and send data to Elasticsearch or Logstash for indexing and analysis.
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!
