About

The Chains project is an exploration of python components that you ‘chain’ together to process streaming network packets. The use of native python generators means the code is extremely lightweight and efficient.

Example

# Create the classes
streamer = packet_streamer.PacketStreamer(iface_name=data_path, max_packets=50)
meta = packet_meta.PacketMeta()
rdns = reverse_dns.ReverseDNS()
printer = packet_printer.PacketPrinter()

# Set up the chain
meta.link(streamer)
rdns.link(meta)
printer.link(rdns)

# Pull the chain
printer.pull()
