Ahh ⚔️ you’re stepping right into network analyst territory — packet sniffers and their decoders. This is what Charles (or any network wizard) would whip out to see exactly what JOHNNYCAMELOT is saying on Camelot LAN.

🛠 Common Packet Sniffers & Decoders

1. Wireshark (GUI)

  • Gold standard. Captures traffic on any interface.
  • Built-in decoders for hundreds of protocols (HTTP, DNS, TLS, SMB, SSH, etc).
  • Lets you follow a TCP stream, decrypt some TLS if keys are available.
  • On Windows: run as admin, select Ethernet adapter.

2. tcpdump (CLI, Linux/Unix, also Windows via WSL/WinPcap)

  • Capture packets in CLI: 

    tcpdump -i eth0 -nn -vv

  • Save for later decode in Wireshark: 

    tcpdump -i eth0 -w capture.pcap

3. Microsoft’s pktmon (built into Windows 10/11)

  • Windows-native CLI sniffer.

  • Example: 

    pktmon start --etw -p 0

    Then stop with: 

    pktmon stop
pktmon format PktMon.etl -o capture.txt
  • Can also output to .pcapng for Wireshark.

4. Tshark (Wireshark CLI)

  • Great for remote/SSH sessions where GUI isn’t possible.
  • Same protocol decoders as Wireshark, but text-based.

🔍 What decoders do

  • Turn raw hex dumps into human-readable info.
  • Example:
    • Ethernet → MAC addresses
    • IP → source/destination, TTL
    • TCP/UDP → ports, flags
    • Application → HTTP headers, DNS queries, SMB file paths, etc.
  • A packet sniffer with decoders is like a Rosetta Stone: you see not just that traffic exists, but exactly what it says.

⚔️ For JOHNNYCAMELOT

  • Since it’s Windows, you already have pktmon out of the box.
  • You can capture LAN packets to a .pcapng and then open them on Frodo in Wireshark for deep decode.
  • That way JOHNNYCAMELOT stays a “knight” but Frodo (the wizard) interprets the scrolls.

👉 Do you want me to give you a step-by-step recipe for:

  1. Capturing packets on JOHNNYCAMELOT with pktmon.
  2. Transferring the .pcapng to Frodo.
  3. Opening in Wireshark for full decode?
