Hardware Hacking

Firmware Hacking

You can create your own firmware, it's explained here.

Already hacked firmware

Dave Walker created a hacked firmware that you can just download and use (Thank you Dave!):

Software for the TeraStation

I will add small software packages as .tgz here for you to install onto the TeraStation.

As a rule, you should be able to use most Debian PowerPC packages built for woody. Use ftp to access ftp.de.debian.org (or another mirror), go to pub/debian/pool/main/ and to the directory named with the first letter of what you are looking for, there you should find a directory for the package; download a suitable version (should have "woody" and "powerpc" in the name), unpack it on a Debian box using "dpkg-deb -x package.deb name-of-temporary-dir", remove any clutter (man pages) from your temporary directory, create a tar file and copy it over to the TeraStation.

(NB I wanted to upload a .tgz but the Wiki didn't let me, saying that .tgz was not an accepted image format. --Fred 12:05, 12 Dec 2005 (CET))

Dropbear sshd

A small ssh server. home page

The install package (108k) already contains the proper links to have it start on boot, and it contains two keys for the server. Maybe you want to generate your own set of keys.

Just extract the .tgz as root into the root of your TeraStation:

dmin@HD-HTGL113:~$ sudo -s
root@HD-HTGL113:~# cd /
root@HD-HTGL113:/# tar -xzf /mnt/array1/share/dropbear.tgz

generate your own set of keys:

root@HD-HTGL113:/# rm /etc/dropbear/dropbear_rsa_host_key
root@HD-HTGL113:/# rm /etc/dropbear/dropbear_dss_host_key
root@HD-HTGL113:/# dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key
Will output 1024 bit rsa secret key to '/etc/dropbear/dropbear_rsa_host_key'
Generating key, this may take a while...
Public key portion is:
root@HD-HTGL113:/# dropbearkey -t dss -f /etc/dropbear/dropbear_dss_host_key
Will output 1024 bit dss secret key to '/etc/dropbear/dropbear_dss_host_key'
Generating key, this may take a while...
Public key portion is: 

and reboot.

Can I setup public key authentication on dropbear. If so can someone give me an example. I was able to upgrade the firmware successfully on the Terastation Pro. I am planning to do a Public Key Authentication on my mac and use rsync for backup using ssh protocol. Any ideas? Thanks a gazillion, Naven

Yes you can: Create a key on your Linux/Unix workstation with: ssh-keygen -t rsa The public and private key will be automatically saved to the directory .ssh in your homedir.

Next: copy the text from id_rsa.pub and connect to your Terastation as root.

On your Terastation: - mkdir /root/.ssh - vi /root/.ssh/authorized_keys - paste the text you copied in the step before - save the file

Now you can connect to your Terastation by using public key authentication


Here's a Terastation version.

OpenSSL and OpenSSH and using Winscp (Putty) to Access with Windows


  • Unrar it and transfer openssh-3.0.2p1.tar.gz and openssl-0.9.6e.tar.gz and groups.gz to the TeraStation by copying it to the share.
  • Untar both into the root directory of the TeraStation.
  • Untar groups.gz to /bin
  • Edit /etc/rc.d/init.d/ssh and remove the # from line 14 which mentions AUTOKEYGEN.
  • The following commands make it automatically start on boot and also start now:
  cd /etc/rc.d/rc3.d/
  ln -s ../init.d/ssh S30ssh
  /etc/rc.d/init.d/ssh start

If you've done all the steps correctly then OpenSSH should be running and also start each time you reboot the TeraStation. The version of OpenSSH that was compiled for the Kuro Box actually has a security flaw which was corrected in newer versions of OpenSSH. And now you can Access from Windows too your Tera with Winscp and make Tunnel with Putty. You can trick some Firewall with Putty and Tunnel :-)

What is OpenSSL needed for here? --Aspiers 14:52, 1 July 2007 (CEST)


Using the Rsync protocol daemon is probably the fastest way to read or write data to the TeraStation, and is the method by which the TeraStation backs itself up to other TeraStations. It is in fact shipped with the stock firmware but restricted (usually to other known TeraStations). You have two options: (1) remove or alter the entry from /etc/hosts.deny, or (2) use an ssh tunnel (such as the one available through Dropbear). The first option exposes your TeraStation to anyone on the network. Also, you have to alter the file every time you boot, as the file is regenerated at boot time (For example, this can be done by invoking your generation script at the end of /usr/local/bin/mkrsconf.pl). The second option is much more secure, but the resources needed for the encryption end up reducing your file throughput significantly.

Note: The rsync shipped with the stock firmware has a somewhat short maximum path length (seems to be around 160 characters), so you need to keep your directory tree shallow. Of course, you could always download the Rsync source and compile it with a larger maximum path length. (Using 1.03, I didn't seem to have this problem with long path names. -- SteveK)

Midnight Commander

Encryption, NTFS Support, and Windows Share Management

Aaron explains how he converted his TeraStation to an ETH-disk and gained Encryption, NTFS Support, and Windows Share Management by using an additional Windows system.


See Samba.


See NFS.

Joe 3.2 a good fast editor

Download JOE-3.2 and untar into the root directory and run it with the command



  joe /etc/rc.d/init.d/ssh

The hotkey for help ist

Webmin installation on Terastation

I just managed to install Webmin on my Terastation. It was pretty simple, really. Just download the GZIP, unzip/untar into /root then run "./setup.sh /usr/local/webmin". I found it needed to go into /root to make some of the perl scripts to work. The only thing I had to change from the default was the location of PERL. It installs itself as another web server (<your terastation address>:10000). I'm still having a bit of trouble getting it to restart after a reboot, but once it is running you can look around in your system, adjust Samba settings, look at printers, log files, cron files, etc.

Success reports

This is an old list of people reporting success with some of the above hacks. If you are successful (or not) with any of them, or want to add any other comments about them, please do not add to this list - instead, please add a comment under the relevant section. That way, people can see all the comments about ssh in one place, all the comments about NFS in another, and so on - makes for a much better structured wiki. Thanks!

    • upgraded to Dave's hacked Firmware v1.12 on a v1.12 Terastation
    • added Midnight Commander (starts with a little codepage fault, but notthing really important)
    • didnt get the lundftpd working yet, the service doesnt start (no errorlog), if i try to start it manually with the -v string a "segmentation fault" pops up
  10. torbens
    • 27 April 2006: 1st station updated to Dave's v2.08a using Japanese firmware updater

  12. Entropy 2006-May-20
  13. --Luminaire 11:14, 31 May 2006 (CEST)
    • Used successfully on TS HD-H1.0TGL/R5 (1.12 firmware). Works a treat. Going to try NFS/NIS.

Used successfully on TS-1.0TGL/R5 Works but damn is this thing slow. Truly bound by pathetic CPU. Doesn't even begin to test the Gigabit network

  1. -- Kimbotha 14:57, 25 October 2006 (CEST)
    • 24 October 2006: Updated new 1TB Terastation from v1.12 to Dave's v2.10a - Failed first time, reapplied v2.10a and it nows works fine.
    • Installed dropbear following instructions successfully
    • Tried to install kernel mode nfs as per instructions but failed to load modules
    • installed user mode nfs as per Entropy's instructions successfully
    • currently looking to build a cross toolchain so I can build unfs3 as I need >2GB file support
  2. -- Kimbotha 16:37, 25 October 2006 (CEST)
    • While collecting the components to try and start build a cross compile toolchain I found an set of nfs kernel modules and the nfs kernel daemon here (http://downloads.linkstationwiki.net/terastation/kernel_modules/). These seem to load fine on my TS (with a change to the /etc/init.d/nfs-kernel-server to allow rpc.mountd to start). Will try and run some tests on >2GB files when I have some on there to work with.
