# Protocol Reverse Engineering

Comprehensive techniques for capturing, analyzing, and documenting network protocols for security research, interoperability, and debugging.

## Traffic Capture

### Wireshark Capture

```bash
# Capture on specific interface
wireshark -i eth0 -k

# Capture with filter
wireshark -i eth0 -k -f "port 443"

# Capture to file
tshark -i eth0 -w capture.pcap

# Ring buffer capture (rotate files)
tshark -i eth0 -b filesize:100000 -b files:10 -w capture.pcap… load the full skill through Skill Me
