Alias /mirror-debian/ /var/www/mirror-debian/
<directory>
AllowOverride None
Options -MultiViews FollowSymLinks Indexes
Order allow,deny
Allow from all
</directory>
Step 5: Start initial download
# su - apt-mirror -c apt-mirror
Step 6: Configure your clients to use the new repository
deb http://your.hostname/mirror-debian/debian/ lenny main contrib non-free
deb-src http://your.hostname/mirror-debian/debian/ lenny main contrib non-free
deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free
Thats all!
