Nous utiliserons squid qui permet de réecrire certaines url (celles correspondant aux dépots) grace à un script python.

Exemple :
- on demande http://archive.ubuntu.com/ubuntu/pool/a/alien_1.2.3.deb
- Squid transmet l'url au script python
- le script retranscris en adresse locale : http://127.0.0.1/ubuntu/pool/a/alien_1.2.3.deb
- Si le fichier local existe, le script renvoi l'url locale, sinon renvoi l'url non modifiée

Voici le script en question /usr/local/bin/squid-redirector.py :

??

Modifiez la config de squid de la façon suivante :

url_rewrite_program /usr/local/bin/squid-redirector.py

Le mirroir ubuntu peut se télécharger grace à debmirror avec la configuration suviante :

#!/bin/bash

## Setting variables with explanations.
