- After 2min, telnet to cloudbox:

telnet lacie-cloudbox

/etc/unicorn/unicorn_conf # uname -a
Linux LaCie-CloudBox 2.6.31.14-svn7493 #1 Fri Oct 17 14:00:51 UTC 2014 armv5tel GNU/Linux

 cd /etc/initng/runlevel
 cp default.runlevel default.runlevel.bak
 sed -i '/^#sshd$/s/^#//' default.runlevel

1. Remove comment from sshd in the default.runlevel file, so initng will start it at boot time: 
 cd /etc/initng/runlevel
 cp default.runlevel default.runlevel.bak
 sed -i '/^#sshd$/s/^#//' default.runlevel

2. Enable sshd in Unicorn 
 cd /etc/unicorn/unicorn_conf
 cp unicorn.sharing.ssh.conf unicorn.sharing.ssh.conf.bak
 sed -i '/enabled:.*false/s/:.*/: true/' unicorn.sharing.ssh.conf

2. Enable root login for sshd (necessary on first manual start apparently)
cd /etc/ssh
cp sshd_config sshd_config.bak
sed -i '/PermitRootLogin.*no/s/no/yes/; /AllowUsers/s/$/ root/' sshd_config

3. Start sshd 
 ngc --start sshd

You should now be able to connect on port 2222.

4. On client. Setup .ssh/config:

Host lacie
    User                root
    HostName            lacie-cloudbox.local
    ProxyCommand        none
    ForwardX11          no
    ForwardX11Trusted   no
    Port                2222

5. Connect

    ssh lacie

    [root@LaCie-CloudBox ssh]#

Voilà!

Q: HOW COME I CAN NAME RESOLV ON LACIE-CLOUDBOX WITHOUT HOSTS FILE?
--> uses nmblookup. But it gives bad address if remote pc has both eth0 + wlan0

TODO:
- Force lacie-cloudbox to use wired ip address when available (not the wlan)
- Don't exclude completely /var/log, but only some of them (eg. rsync.log)
- Disable rsyncd transfer logging on client
- Configure email notification

NTP CONFIGURATION:
Frequent time desync.
Change server to 0.ubuntu.pool.ntp.org
