packrat-cli 1.1.2

🐀 A clean, human-readable CLI packet analyzer for .pcap files

packrat 🐀

Packrat is an open source command-line packet analyzer that takes the pain out of reading raw .pcap files. Packrat gives you a clean, colorized summary of IP conversations, protocol breakdowns, and traffic detection.

After using tshark I just wanted something simpler. Something I could run and immediately understand what's happening in a capture without digging through documentation for flags.

If you are using this tool and have any suggestions, feel free to open an issue or reach out!

install

pip install packrat-cli

usage

# basic analysis
packrat capture.pcap

# filter by IP or protocol
packrat capture.pcap --filter 192.168.1.5
packrat capture.pcap --filter DNS

# export results
packrat capture.pcap --export json
packrat capture.pcap --export html
packrat capture.pcap --export txt

# skip DNS resolution (faster)
packrat capture.pcap --nd

# check version
packrat --version

NOTE

Packrat reports HTTP at the packet level, not the transaction level. What this means is that since there is no TCP reassembly, A single HTTP request/response may span multiple packets. This can lead to a higher number of packets according to Wireshark or other Networking tools.

That being said, use Packrat for convenience not pin point accuracy.
