I found Part 1 and Part 2 Hacking the NSLU 2 how-tos on this site. I read through the two guides making sure I can do the same thing on mine. First thing was getting telnet working. Also the guides confirm that it is running Linux. Jim Buxbee how-tos on hacking the NSLU2 has 5 parts to it. After going though the 1st and 2nd one.

I am able to access the device via telnet, but have to turn it on everytime I reboot the device. Later on in his guides he points out that the project uNSLUng is over on sourceforge and they have a new version of the firmware. I downloaded and installed the 3.16-beta version as its the latest and greatest (3.17 has been release since I installed it). It is time to reboot and make sure things are working as they were before since I am using a non-standard version of the firmware. I know that at this point on I no longer have support from Linksys. One of the admin pages showing the drives and size:

Once again I enabled telnet and have to use uNSLUng's root password since I dont have the harddrive installed at this point. Make sure that things are working from what I can tell. I then plugged in the Hatichi drive and started adding the custom applications via the network. Using ipkg to download and install the apps. I installed: Portmapper NFS3.0 dropbear (SSH) mdadm (Software Raid – for when I am ready to add more than 2 disk) OpenSSL OpenSSH (This had a config error and installed dropbear in place of it) MT-daapd (I-tunes server this will work with another project).
