without the expressed written consent of whoever I stole it from.

now that we have the legal stuff covered , let's get started

Installing the ISCSI server

Log into your amahi box via ssh and become root

NOTE: As i have experienced myself it is a good idea to check if your updates are all done correctly . do this by Typing

yum update

let amahi update whatever is necessary to avoid a kernel module error trying to start the ISCSI server.

then install kernel headers and gcc

yum install kernel-headers kernel-devel gcc

now we going to download the install script i wrote

wget http://dl.dropbox.com/u/57179706/iscsi/install.sh

then run sh ./install.sh

this should have now compiled and installed the ISCSI server on your Amahi box

Configuration and creation of an ISCSI disk image

the easiest way to get an iscsi target is to create an image file

we are doing this by typing :

mkdir /var/hda/files/iscsi
dd if=/dev/zero of=/var/hda/files/iscsi/disk.img bs=1M count=0 seek=2560000

you can name the disk.img whatever you want and the numbers behind seek is the size of the image disk which in our case is 250 gigs

now if we look in /var/hda/files/iscsi/ we will find a file called disk.img

Configuring the ISCSI server to serve your disk image

we have to edit the config file in /etc/iet/ietd.conf (use your favorite editor)

Leave everything as it is exept at the bottom we add

Target iqn.2012-02.com.domain:disk.img

Lun 0 Path=/var/hda/files/iscsi/disk.img,Type=fileio

save and exit your editor

start/restart your ISCSI server

service iscsi-target restart

done

I will update this page later on how to hook a ISCSI drive using the win7 iscsi-initiator when i finally figured out why i have no toolbar while editing the wiki page
