$ git clone https://aur.archlinux.org/packetbeat.git
$ cd packetbeat
$ makepkg -si

This will install Packetbeat and all its dependencies.

Step 2: Configure Packetbeat

The Packetbeat configuration file is located at /etc/packetbeat/packetbeat.yml. Open the file in a text editor and customize the settings as per your needs. Here are some important settings:

• interfaces: Set the network interface(s) to listen for traffic on.
• output.elasticsearch: Configure the connection to Elasticsearch.
