Gentoo cross compilation instructions (crossdev -> stage3)

Cross instructions

These instructions cover:

  1. building a cross toolchain
  2. populating the new ROOT
  3. making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Set up the toolchain

Intro

One of Apexlab's strategic partners, Olvasoegylet.io sent us a request for a book catalog application. They would like to have a public collection of books for their customers. You are the chosen one who may write POC (proof of concept) purely back-end (Node) JavaScript (Typescript) application which they could use to provide data for their various mobile application eg.: Book Renter.

NMAP

nmap default

nmap -sC -sV TARGET -Pn -oN nmap/scan -p- -v
scan target for pentest
nmap -PN -n -A -sS -p- -oN output.nmap <IP>
-Pn : no ping check (host is up),
-n no dns resolution
-A : detect systeme info
-sT : tcp connect [laisse des traces dans les logs serveurs] (moins impactant que -sS Syn, ne laisse pas de trace dans les logs par defaut)
-p- : port de 0-65535
-oN output.nmap : write utput to file
ajouter un scan udp en parallèle -sU (dns, ipsec ...)
