Introduction

What is NAS?

NAS is short for “Network attached Storage”, which is used to name a specialized device
that offers mass storage towards a data network. SOHO NAS like the ICY BOX IB­NAS2001 are small devices that simply share data from HDDs to an Ethernet. There are
many approaches; some are using custom shaped methods in offering the storage space
to the network participants. This approach needs special software to be installed on the
network clients and in most cases is limited to one particular operating system.

The ICY BOX IB-NAS2001 has chosen to offer the HDD space in the way common
operating systems are expecting it. This means it uses the same principles (protocols) to
offer HDD-Storage as common file servers are doing it but with less noise, lower power
consumption and in a much simpler way. The main advantage is that, that special
software is unnecessary to access the storage provided, whilst maintaining the maximum
security features, as already offered within the operation system, such as user and group
based access control.

Samba (Windows)

Netzwerk

The samba server implemented in the ICY BOX IB-NAS2001 offers storage in a way
regular Windows shares are doing it (commonly known as SMB or CIFS protocol). Even
Operating systems like MAC OS and Linux are capable of using this kind of network
storage access. It provides a maximum of security by offering the opportunity to limit the
access on users or groups.

4

FTP

Netzwerk

Router

The FTP protocol is one of the oldest ways for file transfer in the internet. It is fast and
could easily be used to access the HDD even via the internet. A huge set of different
software clients exists even for exotic operating systems using this simple but fast
protocol. Most internet access routers used in small offices and at home offer a
mechanism called port forwarding (virtual server, etc.) which could be easily used to
expose the ICY BOX IB-NAS2001’s storage to the internet. The FTP protocol offers access
control based on user and groups.

NFS

In the Unix world the NFS protocol is common to share disk space via network. This
protocol could be used to mount natively network storage to all kinds of Unix operating
systems like Linux, Solaris, etc. The NFS protocol is fast but does not provide a User or
Group based access control server sided. Access control is limited to the definition of
singular or a set of IP-Addresses (host addresses).

More than a NAS

The ICY BOX IB-NAS2001 is not only an easy to use network storage device. It is a truly
double functional HDD box. It offers a complete USB 2.0 HDD access chipset, offering
greater flexibility. Users have the option of using it as a NAS where a network connection
is available or connect it via the much faster USB 2.0 Interface in the same way they do
it with a conventional external hard drive. This dual-functional design provides a
maximum of flexibility to access the data on the ICY BOX anytime anywhere.

USB

5

But the IB-NAS2001 is even more. You can print via Network or, if you like to distribute
Musik or Videos via your network at home, the UPnP-AV protocol can do this directly to
your network media player.

And if that still is not enough: The IB-NAS2001 can be additionally extended by other
Applications.

USB

Printserver

Netzwerk

Attach your printer to the IB-NAS2001 and use it via network from different computer
simultaneously.

6

UPnP-AV

Netzwerk

The included Twonky Media Server (30 days trial version) adapts this standard to as
many players as possible. The Twonky Media Server has been updated several times a
year so far to ensure compatibility to all new players. Therefore we have chosen to not
implement this software fix in the firmware of the IB-NAS2001 but to give the user to
easily upgrade it when a new version is released. A permanent license can be purchased
from the Website of Twonky Media by following a link from the user interface of Twonky
Media.

7

Bonjour and iTunes Support

Netzwerk

The IB-NAS2001 is able to assign its services via Bonjour, so that MAC computer can
easily be connected to the server functions of the IB-NAS2001. Due to the iTunes
support, multimedia files can be accessed via iTunes from anywhere in the network.

Extensibility

The IB-NAS2001 can arbitrarily extended on applications by installing additional software
packages. In contrast to the closed systems of other manufacturer, the IB-NAS2001 is
future-proof and open to new developments.

Usage as external Storage drive

First come first serve

To use the Icy Box IB-NAS2001 as an external storage enclosure all is required is to
connect to the USB interface of a computer. The decision whether the IB-NAS2001 is
operating as an external storage case or as a NAS is determined by the first come first
serve principle. After turning on the IB-NAS2001 the interface which is connected defines
the operation mode.

Attention: Do not connect the USB and the Network interface at the same time!

Once the IB-NAS2001 is connected to USB and power up it acts as a standard external
hard drive.

Attention: To make sure that the IB-NAS2001 operates appropriate as an

external hard drive and as a NAS it is necessary to initialize and
format the hard drive in the NAS modus as described in chapter
“Hard disk initialization” on page19. This is necessary because the

NAS modus needs 2 additional reserved partitions witch are created
during this procedure. To be able to write on that partition on a
Windows computer the chosen file system of the data partition has to be
FAT32.

11

12

If connected to a Windows system the first 2 Partitions created by the NAS setup process
are not visible because the are formatted with a file system windows is not able to use by
default.

Attention: The content of the first two system partitions created by the NAS setup

process must not be changed manually in order to guaranty the
appropriate operation of the IB-NAS2001 in the NAS modus.

To switch between the NAS modus and then external hard drive modus it is first
necessary to turn of the IB-NAS2001, disconnect the old interface, connect the new one
and turn it on again. After that the Modus is chosen in the described way by the first
interface witch is connected at the time of start up.

How to access the Management Interface

The NAS modus is controlled by a web based interface which could be accessed by using
a standard web browser. In a normal network environment this is simply done by
entering “http://icybox” in the address line of the web browser. But whether that works
is determined by the configuration of the network environment.

The following Possibilities are given:

DHCP controlled Network with automatic DNS update

In a DHCP1 controlled Network the ICY BOX IB-NAS2001 is assigned with an IP Address2
by the DHCP server. In case the DHCP server updates this information automatically to
the DNS

3

Server (see RFC 2136). The ICY BOX IB-NAS2001 could be accessed by simply
entering “http://icybox” in the address line of a standard web browser. Continue with
point “Using the management interface” for setting up the IB-NAS2001 on Page 17.

1

DHCP acronym for “dynamic host configuration protocol” names a process witch assigns network parameters to a computer

attached towards a network automatically via a specialized DHCP server. Most DSL routers provide such a service.

2

IP-Address is a 32 bit binary number mostly expressed by a group of four numbers in the Range between 1 and 255

separated by “.” e.g. 169.254.100.100. This is used for addressing hosts in a TCP/IP based Network.

3

DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS
server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet
name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to
address a host or device. The only chance to get access to that host or device is to use the IP Address directly.

DHCP controlled Network without automatic DNS update

In a DHCP controlled Network environment the IB-NAS2001 gets its IP Address from the
DHCP server. If the DHCP server does not update that information to the DNS server the
necessary name resolution for entering “http://icybox” will not work because the DNS
server has no information about the actual IP Address of the IB-NAS2001. To find out the
IP Address you can turn on the UPnP Support in Windows or use the “SearchNAS.exe”
Program on the CD to find out the IP Address.

Click on „Setup“

Click on “Exit”

The actual IP Address of
the IB-NAS2000 is
displayed

IB-NAS2000 is found

To access the web management surface enter “http://

<IP Address>” in the address line

of the Standard Web browser, where

<IP Address> is the IP Address found by

SearchNAS.exe as described above. Continue with point “Using the management
interface” for setting up the IB-NAS2001 on Page 17.

13

Not configured Network / Direct Attachment

If the IB-NAS2001 is attached to a not configured network where no DHCP server
provides the IP configuration (or the IB-NAS2001 is directly attached to the computer)
and the computers are configured to use DHCP (which is default setting) the IB-NAS2001
will activate its own DHCP Server with the default IP Address 192.168.0.1 and will
provide IP Addresses in a range from 192.168.1.2 till 192.168.1.50 with a net mask

4

of

255.255.255.0, which is part of the subnet

5

192.168.1.1-192.168.1.254. In this case the
IB-NAS2001 can be reached by typing “http://192.168.1.1” in the address line of a
standard web browser.

Network configured on fix IP-Addresses

In a network where no DHCP Server is present and all IP-Addresses are configured
manually and fixed for example between 192.168.1.1 and 192.168.1.254 with

255.255.255.0 as net mask, 192.168.1.1 as default gateway

6

and 192.168.1.1 as

DNS server you have to define the IP Address of the IB-NAS2001 also manually.

To configure the IP Address of the IB-NAS2001 to for example 192.168.1.100 please
start the SearchNAS.exe on the CD and proceed as follows:

Attention: If you are unable to run SearchNAS.exe on your computer because you

are not using a Windows operating system please configure the IP­Address of the IB-NAS2001 using the web configuration interface as
described in point “Network Setting” on page 46.

Click on „Setup“

14

4

The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum

necessary part of the network configuration. So it always has to be set appropriate.

5

TCP/IP based networks, as the internet, are structured into different network parts called sub nets. A subnet is built by a set
of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number
containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those
digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate
directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net
traffic from one subnet into another.

6

In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send
data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet
need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded.
This IP Address of the router is defined by the default gateway setting.

Using the management interface

When entering the URL as mentioned in the points above in the address line of the web
browser, for example “http://192.168.1.100” the browser connects to the IB-NAS2001
and displays the management interface of the IB-NAS2001.

The data partition of the IB-NAS2001 could be set up using

File system Description

EXT2 Linux file syste
EXT3 Linux journaling file system
FAT32 Windows file system

These file systems differ in the native ability of different operating systems to access
them directly via USB mode, in their features and limits. That is the reason why no

particular file system is preset for the data partition. Depending on the future use of th
IB-NAS2001 the user has to choose the appropriate one.

A file system describes the way an operating systems stores data to a mass storage device. A file system may include
mechanisms for data organization, naming of files, access control, and system crash stability. Since mass storage management
is a very important task to an operating system a file system is deeply related to its abilities. Different operating systems are
orientated to different kinds of file systems and there philosophy.

The “Refresh” button causes a refresh of the displayed data if the display should not be
actualized automatically.

21

Initializing the hard disk is done in two steps: First choose a file system for the data
partition and second click on “Format” button:

Attention: The choice of the file system has big influence on the features provided

by the NAS. Also important is the fact that not all file system types could
be read by every operating system. This is of great importance when
you plan to use the IB-NAS2001 both as NAS and external storage
device via USB. For details see point “Choosing the appropriate file
system” on page 19.

Attention: Formatting the hard disk will erase all data on the hard disk.

Please save all data on it before proceeding to format it!

Click on “Format” button

Select a file system type,
for example “FAT32”

Click on “OK”

The Status changes to

for his private use, which is only accessible or even displayed by the one who identifies
with that particular username and password. In addition, the disk space that the user can
use should be limited to a maximum of 1000 MByte, so we set a quota

.

Attention: To be able to set a quota the EXT3 file system has to be chosen for the

data partition, because only the EXT3 file system supports that feature.

File server and share management

In this section it explains, how the disk space is provided to the network and how this is
controlled. The Web interface divides this management into two logical parts. Global
server settings and share orientated setting.

35

File Server Settings

What is a file server? – A file server offers disk space to a network. The term server used
to name a service offered to the network. As described in point “What is NAS?” (page 4)
the IB-NAS2001 uses 3 different services to provide hard disk space to the network:
Samba (Windows), FTP and NFS. The basic settings regarding these 3 services are done
in the “File Server” item of the “File” submenu.

 Control Panel

 File

 File Server

All three servers could be disabled separately. The “File Server Setting” form is
structured into 4 parts:

Section Description

Windows Setting basic settings for the Samba service
FTP Server Setting basic settings for the FTP service settings
NFS Server Setting basic settings for the NFS service
Guest Access Setting basic settings for the cross services guest account

Samba basic settings

Guest account settings

NFS basic settings

Ftp basic settings

By enabling the “Enable” checkmark for each section the corresponding service is
enabled or disabled. By default all services are enabled to grant a rapid start up.

Windows Setting

As described in point “Samba (Windows)” (page 4) the Samba server provides the
storage for Windows clients, also MAC OS and Linux computers are able to use network
storage via this service. It has the most complex structure and provides the most
features. Therefore the basic settings are a little more extensive, than those for the other
services.

Windows offers possibility to structure network participants in so called “Workgroups”.
Via this identifier – which is just a name – it gives the opportunity to assort logical units
of network participants to give a better overview. This could be set up in the referring
field on the form. Also you can enter a description term which will be displayed when

36

browsing11 the windows network. If the windows network has a WINS12 server for
providing a network directory, the IP Address could be specified here.

FTP Server Settings

Aside of the possibility to enable or disable the FTP service, the port13 number of that
server could be modified in order to accommodate a possible port forwarding

14

of a

internet access router which uses NAT

15

, for example if it is desired to make two IB-

NAS2001 accessible via port forwarding by an internet access router.

Attention: Changing the FTP servers port from 21 (default) to another value will

cause, that standard FTP client will not be able to access the IB­NAS2001 FTP server, except the changed port number is configured in
the FTP client appropriately.

NFS Server Setting

Here the NFS Server can be enabled or disabled.

Guest Access Setting

By default the IB-NAS2001 has a preconfigured account for guest access respectively
anonymous access. This means that via Windows share and FTP there is a guest
folder/share which could be accessed anonymously without a user/password
authentication.

Attention: Leaving the guest access enabled means a high level security risk when

the IB-NAS2001 is exposed to the internet or any public network. This
can lead to malicious abuse. If you expose the IB-NAS2001 to any

public network, it is strongly recommended to disable the Guest
Access.

The reason why the default setting is enabled is to ensure that the IB-NAS2001 is readily
accessible when used the first time.

In addition to enabling and disabling that feature a Quota for that account could be
defined for restricting the quantity of disk used by users accessing the IB-NAS2001 via
guest settings.

11

Browsing signifies here a process of Windows to discover and display network participants.

12

WINS is an acronym for “Windows Internet Naming service”. Windows knows two ways of name resolution (process of
assigning IP addresses to IP Addresses) one is a broadcast based mechanism and the other is WINS, where some network
participants take over the role of a directory server called WINS server, registering names and services of other network
participants.

13

Network participants in a TCP/IP (Internet) based network structure are addressed via IP Addresses, but as you can see a
network participant can offer for example different services. To address different services at a network participant using a
singular IP Address there is a subordinated identifier called port. The port is specified by a number between 0 an 65535. Ports
between 1 and 1024 are so called “well known ports”, which means that in the internet exists a common assignment of services
towards these ports. For example 21 is commonly used for FTP, 80 is commonly used for http (web). This association is not a
must. The port associated with a service can be changed. The other communicating party then must specify the port number
explicitly, if it differs from the common principle. Such a change of port numbers makes sense if a network participant wants to
offer two different services of the same kind using the same IP Address.

14

Port forwarding names a process where a router using NAT associates a port of the external IP Address to a port and IP
Address of an internal network participant and forward all traffic from outside destinated towards that particular external port
towards the defined internal IP Address and port number.

15

NAT is an acronym for network address translation. Most internet access routers at home are using this technique. It is used
when a router has just one public IP Address for accessing the internet but has to connect several computers of a private
network. So the router maps all traffic from the inside of the network to a singular external IP Address by changing the port
number. It therefore uses a mapping list associating the internal IP Addresses and port of a network communication with an
external port. This list is dynamic and the associations are deleted after a certain period of time. A network participant from
outside therefore can’t address an internal one if the communication hasn’t been initiated from the internal partner.

38

Attention: To be able to set a quota the EXT3 file system has to be chosen for the

data partition, because only the EXT3 file system supports that feature.
If the data partition is formatted with EXT2 or FAT32, this option can not
be selected.

Share16 Management

In this section of the web management surface is defined how the HDD storage is offered
to the network. Here you can create folders, so called shares, and define the access
rights for the different users or groups towards it. For each folder created here the
Windows (Samba), FTP and NFS Access can be defined and restricted.

The share management could be found selecting:

16

The terminology “share” is used for HDD folders made accessible to the network. This terminology is just used in the
Windows/Samba and NFS context. FTP does not use shares to structure the storage offered the Network. How a share is made
accessible to the operating system on client side depends on the operating system. At Windows and MAC each share is
integrated in the local storage treatment like an own drive. Linux integrates in its directory structure at a defined mounting
point. The folder exposed as share is then visible and usable with all it’s contend (directories or files) as an own drive
respectively directory.

There are two major ways of defining the access towards a share. The first is to allow
access for all. Then no access control takes place on the share and everybody can read,
write or even delete data on the share. The second is to define the access rights on user
and group level. There are two different access rights you can give to a user or a group
of users: “Read Only” and “Writable”.

User/group right Description

Read Only The user is only allowed to read or copy a file or directory

on the share

Writable The user is allowed to read, write or delete a file or

directory on the share and also to create new files or

Network Service

The IB-NAS2001 offers a variety of other Network services such as sharing Pictures,
Music and Videos to the local network, DHCP or Downloading/Sharing files over the
internet. The following Table gives you a quick overview:

Network Service Description

DHCP A DHCP server allows configuring all network devices in a

subnet automatically and centralized.
Printer Server Shares a printer via network.
Bonjour Bonjour is a protocol, which broadcasts a list of services

to other network devices. These devices can than

recognize automatically the services offered by the IB-

NAS2001-B. Mac computers use this protocol mainly.
iTunes support This service offers all music and video content stored in

the directory “music” of the “public” share to all iTunes

programs in the local network.
Twonky Media A UPnP-AV17 server, which allows to broadcast music,

picture and video content to network media players in the

local network. Twonky Media is integrated as 30 days trial

version and can upgraded to a full version by simply

purchasing a license from Twonky Vision.

DHCP Server

A DHCP Server allows centralized configuration of all network devices which are set up to
automatically detain an IP-Address. A network device, which has been set to auto
configuration, looks for a DHCP server during start up and asks this server for an IP­Address. In a home network this service in most cases is provided by the internet access
router (for Example a DSL router). Having two DHCP servers active in a network is
possible but only recommended for professional computer users, knowing exactly what
they are doing.

Attention: Having two DHCP services run in the same network can cause network

failure. Anyone, who does not know how to configure two DHCP servers
correctly, should better deactivate the DHCP Server function of the ICY
BOX, if there is already a DHCP server in the same subnet.

Automatic DHCP configuration

When the IB-NAS2001-B is configured to automatically obtain an IP-Address by DHCP
and it can’t find a DHCP server when starting up, the IB-NAS2001-B assigns itself the
IP-Address 192.168.1.1 with a subnet

UPnP-AV is a standard introduced by Microsoft to allow home entertainment devices to communicate and distribute music,
picture and video data over a local network. By using this protocol a network media player connected to a TV might be able to
access these data stored on the IB-NAS2001.

18

TCP/IP based networks, as the internet, are structured into different network parts called subnets. A subnet is built by a set
of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number
containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those
digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate
directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net
traffic from one subnet into another.

19

The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum
necessary part of the network configuration. So it always has to be set appropriate.

automatically its DHCP Server, distributing IP-Addresses from 192.168.1.2 to

192.168.1.50 with a Maximum Lease Time of 1 day. This behavior ensures an easy auto
configuration of the IB-NAS2001-B in a Network with no auto configuration
infrastructure.

Default Gateway

20

IP-Address of the default gateway. The default gateway in
a home network is mostly the IP-Address of the internet
access router.

Primary DNS

21

IP-Address of the DNS server. The DNS server in a home
network is mostly the IP-Address of the internet access
router.

20

In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send
data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet
need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded.
This IP Address of the router is defined by the default gateway setting.

21

DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS
server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet
name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to
address a host or device. The only chance to get access to that host or device is to use the IP Address directly.

50

51

DHCP Setting Description

Secondary DNS An alternative DNS server.
Other DNS Another alternative DNS server.
DHCP IP Address Start Start of the range of IP-Addresses which form the pool

out of that the DHCP server distributes the IP-Addresses

to the asking clients.
DHCP IP Address End End of the IP-Address range.
Maximum Lease Time Maximum period of time in which the distributed

IP-Address is valid. Clients normally try to update the IP-

Address at half of this time. The longer this period is the

more likely it is that the DHCP server runs short with

addresses.

Printer Server

The IB-NAS2001-B is able to share an attached printer to all computers in the local
network. It does not matter if it is connected to the front or rear USB port, but because
the One Touch Backup function only works to USB-Sticks or USB-HDDs connected to the
front interface, it is better to choose the rear USB port to connect the printer. If the
printer is connected and the Printer Server has been enabled, it is possible to print from
any computer connected in the local network on the printer attached to the IB­NAS2001-B.

Bonjour (including iTunes support)

Bonjour is a protocol to distribute service information among network devices. This
protocol is mainly used by Mac computers. Enabling the support of this protocol simplifies
the use together with Mac computers. If Bonjour is enabled, the iTunes support could be
enabled too. The iTunes support distributes the content of the “music” directory in the
“public” share to all iTunes programs in the local network. So if iTunes is enabled, the
content of the “music” directory in the “public” share can be played directly using iTunes
on any computer in the network.

Twonky Media

The IB-NAS2001-B includes a 30 days trial version of the Twonky Media server. The
Twonky Media server is a UPnP-AV server. UPnP-AV is a protocol which allows network
media players to communicate with the IB-NAS2001 and access media content stored on
the IB-NAS2001-B, such as music, pictures or video.

Install Twonky Media

The Twonky Media server is not part of the firmware of the IB-NAS2001-B. So it has to
be installed on the IB-NAS2001-B first. The reason why Twonky Media needs to be
installed on the IB-NAS2001-B is, that Twonky Media will be updated several times a
year. This will be done because Twonky Vision adapts this media server to various new
media players each year. In order to keep you up to date you can download the latest
Twonky Media Version from the RaidSonic Homepage:

http://www.raidsonic.de

To install the twonky media server you simply have to copy the “twonkymedia” directory
with all subdirectories to the “applications” directory of the “public” share. You can find a
Twonky Media version on the CD-Rom, which is part of the delivery of the IB-NAS2001.

52

If you download the latest version of Twonky Media from the homepage mentioned above
you might have to unpack the downloaded file first to disk of your local computer and
then copy the resulting “twonkymedia” directory to the “applications” directory in the
“public” share of the IB-NAS2001-B.

How to set up your computer to access a share on the IB-NAS2001-B is described in

USB-Sticks and USB hard discs

The IB-NAS2001-B can be extended with external USB mass storage devices, such as
USB-Sticks or USB hard discs. The IB-NAS2001-B so far supports up to 2 external
storage devices, since it has 2 USB 2.0 interfaces. If one of these interfaces is already
used for a USB Printer the IB-NAS2001-B supports only one USB mass storage device.

Supported file systems

As on the internal hard discs the IB-NAS2001-B supports EXT2, EXT3 and FAT32 on
external mass storage devices. The IB-NAS2001-B supports only one partition per mass
storage device. If the mass storage device has more than one partition, only the first
partition will be recognized.

USB access via Network

If any USB mass storage device with a compatible file system is attached to any USB
interface of the IB-NAS2001-B it will automatically be recognized and a share containing
the fist partition of the external USB mass storage device will be created and presented
to the network without any password restriction. The name of the share is
“usb

<number>”, where <number> is a number counted up from 1 in the chronological

order of attachment. So the USB mass storage device, which is attached first will become
the share “usb1” and the second “usb2”.

How to set up your computer to access a share on the IB-NAS2001-B is described in
point “Mapping shares and Printers” on page 60.

Extensions

In difference to classical SOHO NAS systems, the IB-NAS2001 can be extended
approximately unlimited. Additional software packages can be installed using the
mechanism described in the following section.

Installation of an application

The installation of an application is pretty simple. The referring installation file has just to
be copied in the “new_software” folder in the “applications” folder in the “public” share,
and the IB-NAS has to be rebooted.

Attention: After the upgrade described above the HDD needs to be initialized in

order to grant that the appropriate folders are generated on the HDD.

Copy the installation file
in the „new_software”
folder in the
“applications” folder in
the “public” share and
restart the IB-NAS
afterwards

Attention: After the installation of packages like the SSH server is it possible that

the restart may take longer, because some keys for the strong
encryption have to be generated.

To restart the system is done via the menu item "Turn Off Server":

 Control Panel

 System

 Turn off Server

To restart or turn off the
IB-NAS2000, please click
on the referring button

In most cases, the application will integrate itself in seamlessly in the menu structure of
the management surface. For a detailed description please view the documentation along
the referring application.

Einführung

Was ist NAS?

NAS ist die Abkürzung für “Network Attached Storage” und wird gebraucht um Geräte zu
bezeichnen, die Massenspeicher in einem Netzwerk anbieten. SOHO NAS wie das IB­NAS2001 sind kleine Geräte, die Daten von einer Festplatte im Netz zur Verfügung stel­len. Es gibt nun einige Ansätze für diese Problemstellung. Einige nutzen spezielle proprie­täre Methoden den Speicherplatz im Netzwerk anzubieten. Dieser Ansatz benötigt spe­zielle Software, die auf den Clients installiert werden muss, was sie in den meisten Fällen
auf ein bestimmtes Betriebsystem beschränkt.

Das IB-NAS2001 hat nun einen Weg gewählt, den die üblichen Betriebssysteme natürli­cherweise erwarten. Das heißt, dass es dasselbe Prinzip (Protokoll) verwendet Speicher­platz bereit zu stellen, wie es üblicherweise Fileserver tun, aber leiser, stromsparender
und viel einfacher. Der Hauptvorteil besteht nun darin, dass so keine proprietäre Soft­ware zum Zugriff auf die Daten benötigt wird und die betriebssystemeigenen Sicher­heitsmechanismen zum Einsatz kommen wie Benutzer und Gruppen basierte Zugangs­kontrolle.

Samba (Windows)

4

c

Netzwerk

Der Samba Server, der im IB-NAS2001 implementiert ist, bietet Speicher in der Weise
an, wie es reguläre Windows Netzlaufwerke tun (gemeinhin als SMB oder CIFS Protokoll
bekannt). Auch Betriebssysteme wie das MAC OS oder Linux sind in der Lage, auf diese
Art des Netzwerkspeichers zuzugreifen. Das bietet ein Maximum an Sicherheit, durch die
Möglichkeit den Zugriff auf bestimmte Benutzer oder Gruppen zu beschränken.

FTP

Netzwerk

Router

Das FTP Protokoll ist eine der ältesten Arten der Dateiübertragung im Internet. Es ist
schnell und bietet einen einfachen Zugriff auf die Festplatte auch über das Internet. Es
existiert eine große Menge an Softwareclients auch für die exotischsten Betriebssysteme,
die dieses einfache aber schnelle Protokoll verwenden. Die meisten Internet Access Rou­ter, die in kleinen Netzen und Zuhause zum Einsatz kommen, bieten einen Mechanismus
an, der Port Forwarding (Virtual Server, etc.) genannt wird und auf einfache Weise dazu
verwendet werden kann den Speicherplatz des IB-NAS2001 dem Internet zur Verfügung
zu stellen. Das FTP Protokoll bietet ebenfalls Benutzer und Gruppen basierte Zugriffskon­trolle.

NFS

In der Unixwelt ist das NFS Protokoll weit verbreitet um Festplattenplatz im Netzwerk
gemeinsam zu Nutzen. Dieses Protokoll kann dazu verwendet werden um in natürlicher
Weise Netwerkspeicher allen arten von Unix basierten Betriebssystemen zur Verfügung
zu stellen. Die Zugriffskontrolle ist begrenzt auf die Definition von einzelnen oder ganzen
Bereichen von IP-Adressen (Hostadressen).

Mehr als NAS

Das IB-NAS2001 ist nicht nur ein einfach zu bedienendes Netzwerkspeichergerät. Es hat
eine echte Doppelfunktion. Es bietet einen kompletten USB 2.0 Festplattenchipsatz und
somit mehr Flexibilität. Der Anwender hat die Möglichkeit es, wo immer eine Netzwerkinf­rastruktur zur Verfügung steht, als NAS zu Nutzen oder es mit Hilfe der viel schnelleren
USB 2.0 Schnittstelle als konventionelles externes Speichergehäuse zu betreiben. Das
doppelfunktionale Design ermöglicht ein Maximum an Flexibilität die Daten auf der ICY
BOX wann immer und wo immer zu nutzen.

USB

5

Aber das IB-NAS2001 ist mehr. Sie können via Netzwerk drucken oder, wenn sie Musik,
Bilder oder Videos über ihr Netzwerk zuhause übertragen wollen, dies mit dem UPnP-AV
Protokoll direkt mit ihrem Netzwerkmediaplayer tun.

Und wenn das immer noch nicht reicht: Das IB-NAS2001 kann beliebig um weitere Appli­kationen erweitert werden.

Printserver

Netzwerk

Sie können ihren Drucker an das IB-NAS2001 anschließen und den Drucker über das
Netzwerk von verschiedenen Computern aus gemeinsam nutzen.

6

UPnP-AV

Netzwerk

Der im Lieferumfang enthaltene Twonky Media Server (30 Tage Testversion) passt diesen
Standard an so viele Netzwerkmediaplayer wie möglich an. Der Twonky Media Server
wird von Twonky Vision mehrmals im Jahr auf den neuesten Stand gebracht, um die
Kompatibilität mit möglichst vielen Playern zu gewährleisten. Deshalb ist der Twonky
Media Server nicht fest in der Firmware des IB-NAS2001 integriert, um dem Anwender
die Gelegenheit zu geben, den Server auf die neueste Version aufzurüsten. Eine perma­nente Lizenz kann auf der Webseite von Twonky Media erworben werden, auf die ein Link
von der Benutzeroberfläche des Twonky Media Servers führt.

7

Bonjour und iTunes Support

Netzwerk

Das IB-NAS2001 ist in der Lage seine Netzwerkdienste per Bonjour zu annoncieren, so
dass MAC Computer leichter die Verbindung zum IB-NAS2001 herstellen können. Dank
des iTunes Supports können Multimediadateien von überall im lokalen Netzwerk per iTu­nes abgespielt werden.

Erweiterbarkeit

Das IB-NAS2001 kann beliebig über das Installieren von weiteren Softwarepaketen um
weiter Applikationen erweitert werden. Im Gegensatz zu geschlossenen Systemen der
meisten anderen Hersteller ist das IB-NAS2001 dadurch zukunftssicher und offen für
neues.

Gebrauch als externes Festplattenlaufwerk

First come – first serve

Um das ICY BOX IB-NAS2001 als externes Festplattenlaufwerk zu nutzen muss es ledig­lich über die USB Schnittstelle angeschlossen und eingeschaltet werden. Ob das IB­NAS2001 als externes Festplattengehäuse oder als NAS arbeitet wird dadurch entschie­den, welche Schnittstelle angeschlossen ist, wenn das IB-NAS2001 eingeschaltet wird.

Achtung: Nicht die USB und die Netzwerkschnittstelle gleichzeitig verwenden!

Wenn das IB-NAS2001 mit der USB Schnittstelle verbunden ist und eingeschaltet wird,
arbeitet es als externes Festplattengehäuse.

Achtung: Um sicherzustellen, dass das IB-NAS2001 sowohl als externes

Festplattengehäuse und als NAS verwendet werden kann, ist es
notwendig, dass die enthaltene Festplatte im NAS Modus des IB­NAS2001 initialisiert und formatiert wird, wie in Punkt
“Initialisierung der Festplatte” auf Seite 19 beschrieben. Das ist

notwendig, weil der NAS Modus 2 zusätzliche reservierte Partitionen be­nötigt, die während dieses Prozesses angelegt werden. Um mit einem
Windows Computer via auf die Datenpartition schreiben zu können
muss, diese mit FAT32 formatiert sein.

11

12

Wenn das IB-NAS2001 mit einem Windows System verbunden ist, sind die ersten beiden
Partitionen, die mit dem NAS Einrichtungsprozess erzeugt werden, nicht sichtbar, da sie
mit einem Dateisystem formatiert sind, dass Windows nicht lesen kann.

Achtung: Der Inhalt der ersten beiden Partitionen, die mit dem NAS Einrichtungs-

prozess erzeugt wurden, darf nicht manuell verändert werden um die
ordnungsgemäße Funktion des IB-NAS2001 im NAS Modus zu gewähr­leisten.

Um vom NAS Modus zum externen Festplattenmodus und umgekehrt umzuschalten,
muss das IB-NAS2001 zunächst ausgeschaltet werden, dass alte Schnittstellenkabel ge­trennt werden, dass neue verbunden werden und dann das Gerät wieder eingeschaltet
werden.

Zugriff auf die Managementoberfläche

Der NAS Modus wird über eine Webbasierte Benutzerschnittstelle kontrolliert, die über
einen Standard Webbrowser erreicht werden kann. In einer normalen Netzwerkumge­bung kann das über die Eingabe von „http://icybox“ in der Adresszeile des Webbrowsers
erreicht werden. Ob das funktioniert hängt von der Konfiguration dieser Netzwerkumge­bung ab.

Die folgenden Möglichkeiten existieren:

DHCP gesteuerte Netzwerkkonfiguration mit automati­schem DNS Update

In einer DHCP1 kontrollierten Netzwerkumgebung wird der ICY BOX IB-NAS2001 die IP­Adresse

2

über einen DHCP Server zugewiesen. Wenn der DHCP Server diese Information

automatisch beim zuständigen DNS Server

3

einträgt (siehe RFC 2136) kann das IB­NAS2001 einfach durch Eingabe von „http://icybox“ in der Adresszeile des Webbrowsers
erreicht werden. Fortsetzung mit „Gebrauch der Managementoberfläche“ auf Seite 18 um
das IB-NAS2001 einzurichten.

1

DHCP ist eine Abkürzung für „dynamic host configuration protocol“ und bezeichnet einen Vorgang, in dem die notwendigen
Netwerkeinstellungen automatisch von einen speziellen DHCP Server zugewiesen werden. Die meisten DLS Router bieten einen
solchen Dienst an.

2

Eine IP-Adresse is eine 32 bit Binärzahl die meistens durch eine Gruppe von vier Dezimalzahlen zwischen 1 und 255 getrennt
durch punkte dargestellt wird. Sie wird zur Adressierung von Rechnern in einem TCP/IP basierten Netzwerk verwendet.

3

DNS ist die Abkürzung für „domain name service“. Das bezeichnet einen Prozess in dem Internet Namen IP-Adressen zuge­ordnet werden. Der DNS Server kann mit einem Telefonbuch verglichen werden. Bei DNS Server schlagen alle Internet Applika­tionen die zu einem Internet Namen gehörige IP-Adresse nach. Ohne diesen Dienst oder wenn der DHCP Server den Internet
Namen nicht kennt kann der Internet Name nicht zur Adressierung verwendet werden. Die einzige Chance dann auf ein Gerät
im Netzwerk zuzugreifen ist, direkt die IP-Adresse zu verwenden.

DHCP gesteuerte Netzwerkkonfiguration ohne automati­sches DNS update

In einem Netzwerk in dem die Netzwerkkonfiguration über einen DHCP Server vergeben
wird bekommt das IB-NAS2001 die IP-Adresse vom DHCP Server zugewiesen. Wenn der
DHCP Server diese Information nicht bei dem zuständigen DNS Server aktualisiert, funk­tioniert die notwendige Namensauflösung für „http://icybox“ nicht, denn der DNS Server
hat keine Information über die zugehörige IP-Adresse des IB-NAS2001. Um die IP­Adresse des IB-NAS2001 herauszufinden, kann man die UVPnP Unterstützung von Win­dows aktivieren oder das Programm „SearchNAS.exe“ von der beiliegenden CD benutzen.

Auf „Setup“ Klicken

Auf „Exit“ klicken

Die IP-Adresse des IB­NAS2000 wird hier ange­zeigt

IB-NAS2000 gefunden

Um auf die Management Oberfläche zuzugreifen, nun „http://

<IP-Adresse>“ in die Ad-

resszeile des Standard Webbrowsers eingeben, wobei

<IP-Adresse> die IP-Adresse ist

die wie oben gezeigt mit SearchNAS.exe gefunden wurde. Fortsetzung mit „Gebrauch der
Managementoberfläche“ auf Seite 18 um das IB-NAS2001 einzurichten.

13

14

Nicht konfiguriertes Netzwerk / direkt angeschlossen

Wenn das IB-NAS2001 an ein nicht konfiguriertes Netzwerk angeschlossen wird, in dem
kein DHCP Server die IP-Konfiguration liefert (oder das IB-NAS2001 direkt an den Com­puter angeschlossen wird) und die Computer (der Computer) eingestellt sind, die IP­Adresse per DHCP zu beziehen (Voreinstellung), dann wird das IB-NAS2001 seinen eige­nen DHCP Server aktivieren mit der voreingestellten IP-Adresse 192.168.1.1 und wird IP­Adressen aus dem Bereich von 192.168.1.2 bis 192.168.1.50 mit einer Netzwerkmaske

4

255.255.255.0 den an das Netz angeschlossenen Computern zuweisen. Das entspricht
dem Subnetz

5

192.168.1.1-192.168.1.254. In diesem Falle kann das IB-NAS2001 durch

Eingabe von „http://192.168.1.1“ in die Adresszeile des Browsers erreicht werden.

4

Die Netzwerkmaske definiert, welcher Teil der IP-Adresse das Subnetz definiert. Zusammen mit der IP-Adresse ergibt sie die
minimal notwendige Netzwerkkonfiguration für einen Computer zur Teilnahme an einem TCP/IP basierten Netzwerk. Es ist also
zwingend Notwendig, diese Werte regelgerecht zu konfigurieren.

5

TCP/IP basierte Netzwerken wie das Internet sind in sogenannte Subnetze unterteilt. Ein Subnetz wird gebildet durch einen
zusammenhängenden Bereich von IP-Adressen, die alle mit derselben Binärzahl beginnen. Zur Erläuterung: IP-Adressen wer­den immer als 32 Bit Binärzahl interpretiert, die 32 binäre Ziffern enthält. IP-Adressen desselben Subnetzes haben eine be­stimmte Anzahl der linken Binärziffern gemeinsam. Wie viele dieser Binärziffern als Netzwerkadresse interpretiert werden wird
durch die Subnetzmaske oder kurz Netzmaske definiert. Computer desselben Subnetzes können direkt miteinander kommuni­zieren während Computer aus unterschiedlichen Subnetzen nur über einen Relaisposten den sogenannten Router miteinander
kommunizieren können, der die beiden Subnetze miteinander verbindet und den Netwerkverkehr vom einen in das andere
Subnetz weiterleitet.

Mit festen IP-Adressen konfiguriertes Netzwerk

In einem Netzwerk, in dem kein DHCP Server zur Verfügung steht und alle IP-Adressen
manuell und fest vergeben sind, zum Beispiel aus einem Bereich zwischen 192.168.1.2
und 192.168.1.254 mit einer Netzwerkmaske von 255.255.255.0 und 192.168.1.1 als
Standardgateway und DNS Server, muss die IP-Adresse etc. des IB-NAS2001 ebenfalls
entsprechend manuell vergeben werden.

Um die IP Adresse des IB-NAS2001 zum Beispiel auf 192.168.1.100 zu konfigurieren ver­fahre man wie folgt:

Achtung: Wenn SearchNAS.exe nicht angewandt werden kann, da es nur auf Win-

dows Rechnern läuft, kann die IP-Adresse des IB-NAS2001 über die
Webbasiert Managementoberfläche konfiguriert werden wie im Punkt
„Netzwerkeinstellungen“ auf Seite 48 beschrieben.

Auf „Setup“ klicken

Mit „OK“ fortfahren

Die aktuelle IP-Adress­Konfiguration wird ange­zeigt

Wenn die URL wie in den obigen Punkten angegeben in den Webbrowser eingegeben
wird, zum Beispiel „http://192.168.1.100“, verbindet sich der Webbrowser mit dem IB­NAS2001 und stellt die Managementoberfläche des IB-NAS2001 dar.

Anmelden

Die Managementoberfläche ist Passwortgeschützt. Der administrative Benutzername ist
„admin“ und das voreingestellte Passwort ist „admin“.

Auf „Login“ klicken

„admin“ bei „Password“
eingeben (Voreinstel­lung)

„admin“ bei „Username“
eingeben

Struktur der Managementoberfläche

Nach erfolgreicher Anmeldung wird die Managementoberfläche angezeigt. Die Manage­mentoberfläche gliedert sich in die Hauptmenüzeile, die Untermenüspalte und den Konfi­gurationsbereich.

Konfigurationsbereich

Untermenüspalte

Hauptmenüzeile

In der Hauptmenüzeile kann unter den folgenden Punkten gewählt werden

Auswahl Hauptmenüzeile Beschreibung

Control Panel Alle Einstellungen bezüglich der Administration
Personal Info Grundlegende Systeminformationen und -einstellungen
Logout Abmelden

Die Untermenüzeile wird ihren Inhalt der Auswahl bei der Hauptmenüzeile anpassen. In
der Darstellung des Internet Explorers können die Menüpunkte erweitert werden um un­tergeordnete Einträge sichtbar zu machen. In anderen Browsern wird der Submenübaum
immer vollständig angezeigt.

Ausgewählte Menüeinträge werden durch weiße Farbe hervorgehoben.

Initialisierung der Festplatte

Der erste Schritt bei der Konfiguration des IB-NAS2001 sollte die Initialisierung der Fest­platte sein. Das ist notwendig, weil das IB-NAS2001 einen Teil der Einstellungen in spe­ziellen Systempartitionen auf der Festplatte speichert, die erst noch angelegt werden
müssen.

Bei der Initialisierung werden drei Partitionen auf der Festplatte erzeugt und formatiert:

Partition Beschreibung

Systempartition Systemeinstellungen (nicht verändern)
Swappartition Erweiterung des Hauptspeichers (nicht verändern)
Datenpartition Nutzdaten, die im Netz zur Verfügung stehen sollen

20

Achtung: Das IB-NAS2001 benötigt diese besondere Struktur der Festplatte um

ordnungsgemäß als NAS funktionieren zu können. Diese Struktur kann
nicht manuell erzeugt werden, wenn das IB-NAS2001 als externes Fest­plattengehäuse arbeitet. Um das IB-NAS2001 in korrekter Weise als
NAS verwenden zu können, müssen die notwendigen Schritte über den
„Disk Utility“ Dialog wie auf Seite 21 Beschrieben ausgeführt werden.

Auswahl des passenden Filesystems

6

Die Datenpartition des IB-NAS2001 kann mit drei verschiedenen Filesystemen erzeugt
werden:

Filesystem Beschreibung

EXT2 Linux Filesystem
EXT3 Linux journaling Filesystem
FAT32 Windows Filesystem

Diese Filesysteme unterscheiden sich in der grundlegenden Fähigkeit der verschiedenen
Betriebssysteme auf diese Zugriff nehmen zu können (wenn das IB-NAS2001 im exter­nen Festplattenmodus betrieben wird), ihre Fähigkeiten und Begrenzungen. Das ist auch
der Grund, warum kein bestimmtes Filesystem voreingestellt ist. In Abhängigkeit der
zukünftigen Anwendung des IB-NAS2001 muss das passende Filesystem ausgewählt
werden.

Ein Filesystem definiert die Art wie ein Betriebssystem Daten auf einem Massenspeicher ablegt. Ein Filesystem kann Mecha­nismen zu Datenorganisation, Benennung von Dateien, Zugriffskontrolle und Absturzsicherheit des Betriebssystems beinhalten.
Da das Management von Massenspeichern eine grundlegende Aufgabe von Betriebssystemen ist, steht ein Filesystem in engem
Zusammenhang mit dessen Grundfunktionen. Die verschiedenen Betriebssysteme ordnen sich den verschiedenen Arten der
Filesystemen und ihrer jeweiligen Philosophie zu.

Eine Quota ist ein Limit dass einem Benutzer oder Gruppe bei der Benutzung der Festplattenkapazität gesetzt werden kann.

Das Initialisieren der Festplatte wird in zwei Schritten getan. Erst das Filesystem für die
Datenpartition im entsprechenden Auswahlfeld wählen und anschließend auf den „For­mat“ Button klicken:

Achtung: die Auswahl des Filesystems hat großen Einfluss auf die Fähigkeiten, die

das IB-NAS2001 als NAS hat. Außerdem ist von Bedeutung, dass nicht
jedes Filesystem von jedem Betriebssystem im USB Modus gelesen wer­den kann. Das ist von großer Bedeutung, wenn geplant ist, dass IB­NAS2001 sowohl als externe Festplatte als auch als NAS verwenden wol­len. Weitere Details dazu im Punkt „Auswahl des passenden Filesystems“
auf Seite 20.

Achtung: Das Formatieren der Festplatte löscht alle Daten darauf. Deshalb

eventuell darauf vorhandene Daten vorher sichern!

Auf „Format“ klicken

Auswahl des Filesystems
z. B. „FAT32“

Auf “OK” klicken

Der Status wechselt auf
„formatting“

Wenn die Formatierung
beendet ist, muss das
IB-NAS2000 neu starten.

Verwalten von Benutzern und Gruppen

Um den Zugriff aus dem Netzwerk zu beschränken ist das IB-NAS2001 in der Lage Be­schränkungen für Benutzer und Gruppen einzurichten. Ein Benutzer ist ein persönlicher
Bezeichner, der über ein Kennwort identifiziert wird. Ein Benutzer kann Mitglied von einer
oder mehreren Gruppen sein. Zugriffsrechte können also für Benutzer und Gruppen defi­niert werden

26

Benutzerverwaltung (User Management)

Die Benutzerverwaltung findet man unter:

Einen neuen Benutzer erzeugen

Um einen neuen Benutzer zu erzeugen, muss lediglich das leere oben beschriebene For­mular ausgefüllt werden und auf den „Save“ Button geklickt werden. Das nachfolgende
Beispiel zeigt die Vorgehensweise um einen Benutzer mit dem Benutzernamen „testuser“
und dem Kennwort „test“ anzulegen. Der Benutzer soll außerdem ein privates Netzlauf­werk erhalten. Das ist ein privater Ordner, der im Netz zur Nutzung freigegeben wird,
und auf den nur unter Verwendung des zugehörigen Benutzernamens und Kennworts
zugegriffen werden kann. Außerdem soll der gesamte Festplattenplatz, der vom Benutzer

27

in Anspruch genommen werden kann auf 1000 MByte begrenzt werden, durch setzen
einer Quota

.

Achtung: Um eine Quota setzen zu können, muss die Datenpartition mit dem

EXT3 Filesystem formatiert sein, da nur dieses Filesystem dieses Merk­mal unterstützt. Wenn die Datenpartition mit EXT2 oder FAT32 forma­tiert wurde, steht diese Auswahl nicht zur Verfügung.

Hier auswählen für einen
persönlichen Ordner

Hier auswählen für eine
Quota und die Größe im
entsprechenden Feld
dahinter angeben

Auf „Save“ klicken um
den Benutzer anzulegen

Für eine Beschreibung

Hier das Kennwort „test“
eingeben und die Einga­be wiederholen

Hier den Benutzernamen
„testuser“ eingeben

Nach dem Klicken auf den „Save“ Button werden der Benutzer und der zugehörige per­sönliche Ordner angelegt. Ebenso wird die Samba Freigabe erzeugt (Abbildung des per­sönlichen Ordners im Netz) und kann nun einzig unter Verwendung des zugehörigen Be­nutzernamens und Kennworts, das zuvor definiert wurde, verwendet werden. Der per­sönliche Ordner und die Samba Freigabe haben denselben Namen wie der zugehörige
Benutzername.

28

Ändern der Benutzereinstellungen

Um die Benutzereinstellungen zu ändern öffnen Sie die Benutzerverwaltung (User Mana­gement):

 Control Panel

 Users and Groups

 User Management

Wenn der ensprechende Benutzer ausgewählt wird werden alle zugehörigen Einstellungen
angezeigt und können geändert werden.

Hier können weitere Än­derungen vorgenommen
werden

Mit „Save“ werden die
Änderungen ausgeführt

Der Eintrag im „Pass­word“ Feld wurde durch
einige ersetzt. Um
es zu ändern hier einfach
