Overview
-
A tiny battery-powered capture box: two Ethernet ports, a passive tap, and a web page you can open from a phone to start, stop, and download captures.
GoalWalk up to a misbehaving port, plug the box in line, and have a .pcap on my phone in under a minute. No laptop, no mirror-port config.
Open problemsKeeping up with 1 Gbps line rate on a Pi, and fitting everything in a case that doesn't look like a science fair project.
