Packet Streamer Actions Status

Stream filtered network packets using ZeroMQ

Requirements for building

First we need to make sure we have all the appropriate libraries.
Please consult this chart for help with installing the required packages.
If your OS is not listed, please help us fill out the table, or submit a request via github.

OS Commands (as root)
CentOS yum install -y gcc libpcap-devel zeromq-devel
Debian apt update; apt install -y build-essential libpcap-dev libzmq3-dev
Fedora yum install -y gcc libpcap-devel zeromq-devel
Ubuntu apt update; apt install -y build-essential libpcap-dev libzmq3-dev

Compile the Code

Install the required development packages and compile the code

cd src
./compile.sh

Directly print test packets into wireshark/tshark/tcpdump

./test_printer.exe | wireshark -k -i -
./test_printer.exe | tshark -r -
./test_printer.exe | tcpdump -r -

Setup a ZMQ PUB bus to put packets on

Use live2zmq.exe to capture packets from a network interface.
Use pcap2zmq.exe to replay packets from a pcap file.
Any packets received will be published to ZMQ.

./live2zmq.exe -v 1 -i eth0 -Z tcp://*:9999
./pcap2zmq.exe -v 1 -P mypackets.pcap -Z tcp://*:9999

Wireless example

This will configure a wireless adapter in monitor mode
and allow live2zmq to sniff 802.11 packets.

iw dev wlan0 set monitor fcsfail control otherbss
ifconfig wlan0 promisc up
iw dev wlan0 set channel 11
./live2zmq.exe -v 2 -i wlan0 -Z tcp://*:9999

Use a BPF to exclude unwanted packets

./live2zmq.exe -v 2 -i eth0 -Z tcp://*:9999 -f "tcp[tcpflags] & (tcp-rst|tcp-ack) == (tcp-rst|tcp-ack)"

Capturing packets on the ANY interface

You can use live2zmq to capture on the ANY interface by omitting the dev argument. In this case you must implement a filter that excludes the ZMQ stream itself. If you don't, every ZMQ message will generate at least one packet, which will get captured by libpcap and then passed to ZMQ. This in turn will create a rift in the space-time continuum that will destroy all life on Earth. You have been warned.

./live2zmq.exe -v 2 -Z tcp://*:9999 -f "not tcp port 9999"
./pkt_writer.exe --stats -Z tcp://localhost:9999 | wireshark -k -i -

Subscribe to a packet stream

Use pkt_writer.exe to save packets to a pcap file
or to print packets into wireshark/tshark/tcpdump.

./pkt_writer.exe -Z tcp://localhost:9999         | wireshark -k -i -
./pkt_writer.exe -Z tcp://localhost:9999         | tshark -r -
./pkt_writer.exe -Z tcp://localhost:9999         | tcpdump -r -
./pkt_writer.exe -Z tcp://localhost:9999 --stats >shiny_new.pcap
./pkt_writer.exe -Z tcp://localhost:9999 --stats -P shiny_new.pcap

Define a stop condition

Stop after 60 seconds
Stop after 10000 packets
Stop after 100 MB

./pkt_writer.exe -Z tcp://localhost:9999 -P shiny_new.pcap --stats --maxtime 60
./pkt_writer.exe -Z tcp://localhost:9999 -P shiny_new.pcap --stats --maxpkts 10000
./pkt_writer.exe -Z tcp://localhost:9999 -P shiny_new.pcap --stats --maxsize 100

Analysis example

Use analysis_example to dissect ICMP and TCP packets.
It will display pings and new TCP connections.

./analysis_example.exe -Z tcp://localhost:9999

Histogram example

Use hist_ipp to collect a histogram of IP Protocols.
Use hist_tcp to collect a histogram of TCP port numbers.
Use hist_udp to collect a histogram of UDP port numbers.
These binaries will display their histogram when they exit.

./hist_ipp.exe -Z tcp://localhost:9999
./hist_ipp.exe -Z tcp://localhost:9999 --csv
./hist_ipp.exe -Z tcp://localhost:9999 --all
./hist_ipp.exe -Z tcp://localhost:9999 --all --csv

./hist_tcp.exe -Z tcp://localhost:9999
./hist_tcp.exe -Z tcp://localhost:9999 --csv
./hist_tcp.exe -Z tcp://localhost:9999 --all
./hist_tcp.exe -Z tcp://localhost:9999 --all --csv

./hist_udp.exe -Z tcp://localhost:9999
./hist_udp.exe -Z tcp://localhost:9999 --csv
./hist_udp.exe -Z tcp://localhost:9999 --all
./hist_udp.exe -Z tcp://localhost:9999 --all --csv
