Expressway
Chapter 1: Recon — Listening for Opportunity
The Opening Scene
Imagine the network as a vast, silent street—shrouded in shadows. My first step: turn on the headlights and see what’s out there.

1
nmap -p- -T4 -sS 10.10.11.87 -oN initial_tcp_scan.txt
SSH (port 22) greets me and then slams the door in my face. No welcome mat here. The box seems as silent as a ghost. Seasoned hackers know—if you only look for doors, you might miss the windows.
The UDP Angle — Where All the Clues Hide
1
sudo nmap -sU 10.10.11.87 --min-rate 5000
Port 500 lights up. IPsec/IKE. VPN land: hostile territory for most, but a playground for those who know the rules.
