## What it is
A free PDF book, The Cyber Plumber's Handbook, teaching SSH tunneling, port redirection, and SOCKS proxying with practical penetration testing examples. The repository distributes the book under a Creative Commons license, with an optional paid companion lab guide.

## Use cases
- learn SSH tunneling and port forwarding
- pivot through jump boxes during a penetration test
- scan internal networks through SOCKS proxies with proxychains and nmap
- redirect ports to reach services behind a firewall
- prepare for OSCP-style red team scenarios
- browse the internet through a remote SOCKS proxy

## When to choose
- you want a practical, example-driven guide to SSH tunneling and traffic pivoting
- you are a pentester, red teamer, or network engineer learning lateral movement techniques
- you prefer a free self-contained PDF reference

## When to avoid
- you need interactive hands-on labs without purchasing the companion lab guide
- you want a software tool rather than educational material
- you need commercial-use rights, since the license is non-commercial

## Facets
- artifact type: learning-resource
- maturity: maintenance
