Cappy the crappy network capture

Cappy is 🚧 (WORK IN PROGRESS)

Cappy is a network capture project. The goal is to create something that can (crappily) filter / capture network traffic and also allow the user to load pcap programs

The cappy arguments

• list of devices is display (or not)

  • -l or --list: list devices

• device or file is opened

  • -d or --device: open device
  • -i or --input: open file
  • These are mutual exclusive
  • but if neither are given the "any" device is used

• program dispatched or output packet capture

  • -p or --program: dispatch program on open capture (or display packets)
    • This takes a special format argument library:function

• Output capture to file

  • -o or --output: file capture is saved to

• filter capture traffic

  • positional arguments using the tcpdump filter spec

cappy -l
      -[d|i] [device|lookatthiscap.pcap]
      -p libCap.so:TheCappestFunction
      -o whatthecap.pcap
