It is used by Deepfence's [ThreatStryker](https://deepfence.io/threatstryker/) security observability platform to gather network traffic on demand from cloud workloads for forensic analysis. Primary design goals: * Stay light, capture and stream, no additional processing * Portability, works across **virtual machines, Kubernetes and AWS Fargate**. Linux and Windows PacketStreamer **sensors** are started on the target servers. Sensors capture traffic, apply filters, and then stream the traffic to a central receiver. Traffic streams may be compressed and/or encrypted using TLS. The PacketStreamer **receiver** accepts PacketStreamer streams from multiple remote sensors, and writes the packets to a local `pcap` capture file <p align="center"><img src="https://raw.githubusercontent.com/deepfence/PacketStreamer/main/images/readme/packetstreamer.png"/><p> PacketStreamer sensors collect raw network packets on remote hosts. It selects packets to capture using a BPF filter, and forwards them to a central receiver process where they are written in pcap format. Sensors are very lightweight and impose little performance impact on the remote hosts. PacketStreamer sensors can be run on bare-metal servers, on Docker hosts, and on Kubernetes nodes. The PacketStreamer receiver accepts network traffic from multiple sensors, collecting it into a single, central `pcap` file. You can then process the pcap file or live feed the traffic to the tooling of your choice, such as `Zeek`, `Wireshark` `Suricata`, or as a live stream for Machine Learning models. ## When to use PacketStreamer PacketStreamer meets more general use cases than existing alternatives. For example , Use PacketStreamer if you need a lightweight, efficient method to collect raw network data from multiple machines for central logging and analysis. ## Quick Start  For full instructions, refer to the [PacketStreamer Documentation](https://docs.deepfence.io/packetstreamer/). You will need to install the golang toolchain and `libpcap-dev` before building PacketStreamer. ```shell script # Pre-requisites (Ubuntu): sudo apt install golang-go libpcap-dev git clone https://github.com/deepfence/PacketStreamer.git cd PacketStreamer/ make ``` Run a PacketStreamer receiver, listening on port **8081** and writing pcap output to **/tmp/dump_file** (see [receiver.yaml](contrib/config/receiver.yaml)): ```shell script ./packetstreamer receiver --config ./contrib/config/receiver.yaml ``` Run one or more PacketStreamer sensors on local and remote hosts. Edit the **server address** in [sensor.yaml](contrib/config/sensor-local.yaml): ```shell script # run on the target hosts to capture and forward traffic # copy and edit the sample sensor-local.yaml file, and add the address of the receiver host cp ./contrib/config/sensor-local.yaml ./contrib/config/sensor.yaml ./packetstreamer sensor --config ./contrib/config/sensor.yaml ``` ## Who uses PacketStreamer? * Deepfence [ThreatStryker](https://deepfence.io/threatstryker/) uses PacketStreamer to capture traffic from production platforms for forensics and anomaly detection. ## Get in touch Thank you for using PacketStreamer. * [<img src="https://img.shields.io/badge/documentation-read-green">](https://docs.deepfence.io/packetstreamer/) Start with the documentation * [<img src="https://img.shields.io/badge/[email protected]?logo=slack">](https://join.slack.com/t/deepfence-community/shared_invite/zt-podmzle9-5X~qYx8wMaLt9bGWwkSdgQ) Got a question, need some help?
