I couldn't manage at first to get SAMBA working on the Nebula Zero and Hyperion images (not tried on others)
I tried to configure using the PKT Blue Panel - Mount Center - SMB Server - nothing seeming to work.
Here is what I did - I installed SAMBA package (enclosed on this thread to download).
place the file in /tmp and install the IPK through BluePanel or Software Management (in the setup menu) - then reboot
Then edit /etc/samba/smb.conf - this is what I have in my config file
[global]
load printers = no
guest account = root
log file = /tmp/smb.log
log level = 1
security = share
server string = Dreambox %h network services
workgroup = NBOX
netbios name = %h
case sensitive=yes
preserve case=yes
short preserve case=yes
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192
preferred master = no
local master = no
oplocks = no
printcap name = /dev/null
load printers = no
printing = bsd
[Root]
comment = Everything - take care!
path = /
read only = no
public = yes
guest ok = yes
[Harddisk]
comment = The harddisk
path = /media/hdd
read only = no
public = yes
guest ok = yes

and to enable it to start on boot, add this to /var/config/rc.user
this setup got it working and gives me access to two points - Root and Harddisk - and it starts on boot.
Not sure if others had the same issues using SAMBA on the BluePanel, but I did, and this is how I got round it.
