that is a good question and some of you want one.
there is unfortunately no tutorial to make a xbox-router. if anyone has some ideas, feel free to post here.
requirements:
1.1 you need a broadband i-net connection
1.2 you need a external isdn usb box
2. you need a usb-wlan or usb-networkcard
i would suggest to use the pro-installation of gentoox, cause it is bare and there are no not needed apps for a router like kde, X, etc installed.
most of us have broadband like adsl (isdn later if someone has such hardware and is willing to help)
if your xbox has no access to i-net, emerge rsync will not work.
then you have to download a snapshot of the portage.
you can get it here for example
ftp://ftp.tu-clausthal.de/pub/linux/gentoo/snapshots/
download always the latest file (there is a timestamp on the filename)
okay, exctract it to /usr/portage with
tar -xvjpf portage(complete name)
then you need the latest rp-pppoe and ppp files
ftp://ftp.tu-clausthal.de/pub/linux/gentoo/distfiles/
download them and copy them to /usr/portage/distfiles
after that you have to install them with
USE="-X" emerge rp-pppoe
then you have to do an etc-update and type -3, also overwrite the old files.
if this is done, you have to configure your adsl with
adsl-setup
with adsl-start you can connect to i-net if everything went well. on this stage i had a problem with nameresolution. dns didn`t work as expected.
therefore i opened /etc/resolv.conf deleted all the nameserver entries and added a new one with the dns of my isp (internet provider).
emerge sync to update the portage.
a very nice programm is mirrorselect which you should install. it looks for the fastest dl-mirrors to have always full speed.
emerge mirrorselect
to configure it type: mirrorselect -a -s5
okay, the next step is to update the system (actually gentoox v2 is a lil bit outdated)
to do this type:
emerge -u world
atm there are 55 programms to be reinstalled.
attention! the portage is out-dated on current gentoox pro. after updating this file, your make.conf will be replaced if you say yes. So you are going to loose all your settings for compiling (i686 instead of i586). plz make a backup of this file and do first:
emerge portage
or
say no to overwrite
i will continue when it is finished :>
