Root

Custom capsule

I created a custom capsule, a custom firmware which is very easy to do thanks to the provided script.
Not much to say, just execute the script and answer to a few questions.
Then to flash it, you can use the LaCieNetworkAssistant or just drop the capsule file into the share Share/Update and reboot the NAS, which is a method I prefer, less dependent on network operations.
Note that if you use LaCieNetworkAssistant and it fails updating the fw, they tell to disable IPConf support. To do that on linux, once the assistant is launched, right click on its icon in the task bar => preferences.
Example:

New capsule built: '/home/phil/Downloads/lacie/capsule/lacie/5bignetwork2_2.2.8.1.capsule'
After upgrading you can:
- use SSH/SFTP with root privileges with your Lacie NAS with login 'root' (login: root | password: [same as admin password] | Port: 2222)
- use Transmission Web Interface (url: http://YOUR.LACIE.NAS.IP:9091/transmission/web/)
  Don't forget to change the transmission download path.
- access, after configuring port forwarding in your router, from a external network:
  - Lacie Dashboard: http://YOUR.NETWORK.EXTERNAL.IP/
  - Transmission Web Interface: http://YOUR.NETWORK.EXTERNAL.IP:9091/transmission/web/

Authentication

root password can be permanently changed by editing /usr/lib/python2.6/site-packages/unicorn/authentication/local/user.py & looking for 'root:$1...'
This step is automated when you create a custom capsule, see sshd.i.txt
SSH runs on port 2222 and you can make use of /root/ssh/authorised_keys as usual

Misc

Serial port

There is probably a serial port on board giving access to uboot console

New disks

In case we need to play with new disks, keep in mind their UUID must be injected in th eEEPROM, see here

LaCieNetworkAssistant

These are the tools provided on the cdrom. A linux version comes, even with several packagings: auto extractible, tar.gz, rpm and deb
But they are only for i386 and won't work as such on an amd64 system.
Note that I think we can live without them, everything can be done via the web interface and the shared drive.

To try with the deb, we've to force a bit the things (probably it would be better to repackage it)

sudo dpkg -i --force-architecture --force-depends /media/cdrom/Linux/LaCieNetworkAssistant-1.4.1-Linux.deb

It provides a few binaries:

/usr/bin/LaCieNetworkAssistant
/usr/bin/zsudo
/usr/bin/tarTine
/usr/bin/LCtftpd

Installing the existing ia32 libraries is not enough, some are missing:

$ ldd LaCieNetworkAssistant |grep "not found"
libsmbclient.so.0 => not found

To solve it, you can download the i386 version and copy libsmbclient.so.0 to /usr/lib32
But this one has its own dependencies:

$ ldd libsmbclient.so.0 |grep "not found"
libtalloc.so.2 => not found
libwbclient.so.0 => not found

So, same thing, download & copy libsmbclient.so.0 libtalloc.so.2 libtalloc.so.2.0.7 libwbclient.so.0 to /usr/lib32
I got also an error linked to libtdb1 which is in the is32-libs, so again, get it & cp libtdb.so.1 libtdb.so.1.2.9 /usr/lib32
And now:

export GTK_PATH='/usr/lib32/gtk-2.0'

Reset

See LaCie website, it's possible to reset default fw, with or without data loss

Transmission

I restored a vanilla transmission via the custom capsule to get the web interface.
NEVER launch or stop transmission daemon via the LaCie web nterface, it would restore settings.json to its defaults. Note that it might be permanently changed by mangling /etc/initng/transmission.i and /usr/lib/python2.6/site-packages/unicorn/download/torrent.py
There should be a way to disable the LaCie interface, see /usr/lib/unicorn/webapp2/controller/download.py /usr/lib/unicorn/updaterapp/modules/download.py /usr/lib/unicorn/webapp/modules/neko/download.py and /usr/lib/unicorn/unicorn.conf

Once the web interface is active, you can also activate the remote control interface:

• Stop the daemon

ngc --stop transmission

• Edit /lacie/torrent_dir/transmission/settings.json

"rpc-enabled": true,
"rpc-password": "your_password", # note that it will be encrypted next time automatically
"rpc-port": 9091,
"rpc-username": "your_name",
"rpc-whitelist-enabled": "false",
"rpc-authentication-required": "true",

Options are explained here

ngc --start transmission

Now you can use a remote client:

apt-get install transgui

And edit the other settings, amongst others the download-dir to some /shares/...
