map
01 — Networking intermediate map
Learning objectives
- Choose SSH vs ligolo vs chisel for a scenario (bandwidth, UDP, multi-hop, no SSH daemon)
- Stand up a pivot that exposes an internal subnet, not only one port
- Route one tool through SOCKS/proxychains without breaking DNS blindly
- Draw a 2-hop path (A→B→C) and pick where listeners sit
Intuition
SSH flags are scalpels. Ligolo/chisel are when you need a tun/tap or durable SOCKS across hosts that are not “one web port.”
Intermediate path
- Re-quiz whiteboard
-L/-R/-D - Skim overview for dual-NIC / routing mental model
- Work pivoting note — ligolo first, then chisel; keep SSH as fallback
- Labs
Friend wording add-on
| Tool | Use when |
|---|---|
SSH -L/-R/-D | You have shell+SSH and need a narrow hose |
| ligolo-ng | Want TUN into internal nets; cleaner multi-tool routing |
| chisel | HTTP(S)-friendly tunnel / SOCKS when SSH isn't ideal |
Park for later
Masscan-everything through SOCKS; IPv6-only pivots as first class; Registry-hard -R as required (optional stretch).
