Using locally

Run a PacketStreamer receiver

packetstreamer receiver --config [configuration_file]

You can use an example configuration file:

packetstreamer receiver --config ./contrib/config/receiver-local.yaml

You can process the pcap output in a variety of ways:

# pass the output file /tmp/dump_file to tcpdump:
tail -c +1 -f /tmp/dump_file | tcpdump -r -

# Edit the configuration to write to the special name 'stdout', and pipe output to tcpdump:
./packet-streamer receiver --config ./contrib/config/receiver-stdout.yaml | tcpdump -r -

Run a PacketStreamer sensor

sudo packetstreamer sensor --config [configuration_file]

You can use an example configuration file:

sudo packetstreamer sensor --config ./contrib/config/sensor-local.yaml

When running the sensor remotely, edit the configuration file to target the remote receiver.

Testing PacketStreamer

You can generate some test traffic using your favorite load generator - ab, wrk, httperf, vegeta. For example, to use vegeta:

# install vegeta
go install github.com/tsenart/vegeta@latest

echo 'GET http://some_ip:80' | vegeta attack -rate 100 -duration 5m | tee results.bin | vegeta report
