6.5 Network Settings

6.5.1 TCP/ IP Configuration

- 42 -

Configuration of Network Interfaces

 Fail Over (Default)

The system supports the configuration of multiple network interfaces, which

enables you to perform Fail Over or Load Balance functions. Fail over

ensures server availability to the network. If the primary port is

disconnected due to a hardware or cable problem, the secondary port will

replace its network identity. If the failed port resumes the network

connection, it will also resume the role as the primary interface.

- 43 -

 Load Balance

In load balance* mode, the transmission load is distributed among

aggregated network ports.

* An intelligent software adaptive agent will repeatedly analyze the traffic flow from

the server and distribute the packets based on the destination address. Load
balance can only occur on Layer 3 routing protocols (IP or NCP IPX).
Multicast/Broadcast and non-routing protocols, such as NetBEUI and Microsoft IPX,
are transmitted over the primary port.

- 44 -

 Standalone

Standalone settings enable each port to have a unique IP, which allows users

on different network areas to share one GNS-8000B and maintain their

independence from one another in the network. When using this mode, fail

over cannot be used and only LAN 1 can be configured as DHCP server.

- 45 -

Network Speed

Network speed settings provide an advanced option for configuring network speed.

You can select auto-negotiation (default), 10 Mbps, 100 Mbps, or 1000 Mbps. It

is recommended to use the default setting that the server will determine network

speed automatically.

• Obtain IP address settings automatically via DHCP

If your network supports DHCP, GNS-8000B will automatically use DHCP

protocol to retrieve the IP address and related information.

• Use static IP address

To use fixed IP address for network connection, enter fixed IP address, subnet

mask and default gateway.

- 46 -

Primary DNS Server: Enter the IP address of primary DNS server that provides

DNS service for GNS-8000B in external network.

Secondary DNS Server: Enter the IP address of secondary DNS server that

provides DNS service for GNS-8000B in external network.

You can also configure the following settings:

 Enable DHCP server

If there is no DHCP server on your network, you can enable this option to

provide IP address settings to the clients.

Start IP address

The first IP address to be dynamically allocated for DHCP service.

End IP address

The last IP address to be dynamically allocated for DHCP service.

Lease time

Define the lease time for the dynamic IP address.

Primary DNS server

When the system allocates an IP address to your computer, the primary DNS

server address is also specified to it.

Secondary DNS Server

When the system allocates an IP address to your computer, the secondary

DNS server address is also specified to it.

- 47 -

6.5.2 Microsoft Networking

Enable file service for Microsoft networking: If you are using Microsoft

Windows, enable this service to access the files on network share folders. Assign

a workgroup name.

 Standalone Server

Use local users for user authentication.

 NT Domain Member

Use Microsoft NT domain for user authentication.

 AD Domain Member

GNS-8000B supports Windows 2003 AD (Active Directory) to provide quick

and direct import of user accounts to the existing AD server available in your

network. This function helps you to save time and effort on creating user

accounts and passwords and lowers IT maintenance cost by automatic

configuration procedure.

 Server Description: Describe GNS-8000B for users to identify the server.

To use GNS-8000B on the Microsoft Windows OS, you must enable

- 48 -

Microsoft Network Services.

 Workgroup: Specify the workgroup GNS-8000B belongs to. The

workgroup is a computer group unit in Microsoft Windows network for

network sharing.

 AD Server Name: Enter the name of the AD server when AD domain is

selected for authentication.

 Domain Name: Microsoft domain name. Enter the domain name when

you select NT domain or AD domain.

 WINS server

If the local network has a WINS server installed, specify the IP address. GNS-

8000B will automatically register its name and IP address with WINS service.

If you do not want to enable WINS server support, or you do not have a WINS

server on your network, enter 0.0.0.0 in the field for WINS server IP address.

 Domain Master

There is a unique Domain Master Browser for collecting and recording

resources and services available for each PC in the network or workgroup of

Windows. When a domain master browser (Windows NT/ 200x/ XP PC) exists

already in the network, there is no need to configure GNS-8000B as the

domain master.

When you find the waiting time for accessing Network Neighborhood too long,

it may due to failure of an existing master browser, or there is no master

browser available. If the reason is the latter one, you can check the box

Domain Master in this section to configure GNS-8000B as the master browser

to enhance the speed of accessing information on Network Neighborhood.

Data will be distributed and stored among the disks. If a disk fails, you can

replace a new disk with the damaged one, and the system will restore the

data to the new disk. You can also use three disks for RAID 5 and a fourth

disk as a backup disk. If a disk of RAID 5 volume is damaged, the spare disk

can replace that damaged disk, which enhances server stability and

efficiency.

Note: When configuring RAID 5 disk volume, at least 3 disks are

required.

c. RAID 1 Mirroring Disk Volume

Mirroring Disk protects your data by automatically backing up the contents of

one disk onto the second disk of a mirrored pair. This protects your data if

one of the disks fails. However, the storing capacity is equal to a single disk,

as the second disk is used to automatically back up the first one.

d. RAID 0 Striping Disk Volume

Striping disk combines two or more disks into one larger disk. It offers the

fastest disk access but does not have any protection of your data if the

striped array fails. The disk capacity equals the number of disks in the array

times the size of the smallest disk.

- 55 -

e. Linear Disk Volume

You can combine two or more disks into one larger disk. Files will be saved

on physical disks sequentially but does not have a disk failure file protection

function. The overall capacity of linear disk is the sum of all disks.

management and better control of users’ access right, you have to organize users,

user groups and their access right control.

6.7.1 Users

The system has created the following users by default:

 Administrator

By default, administrator has access to system administration and cannot be

deleted.

 Guest

This is a built-in user and will not be displayed on User Management page.

When you use a non-registered user name to login, the server will recognize

the user as a guest and will allow limited access. A guest does not belong to

any user group.

 Anonymous

This is a built-in user and will not be displayed on User Management page.

When you connect to the server by FTP service, you can use this name to

login as a guest.

- 59 -

512 users can be created at maximum (including system default users). You

can create a new user according to your needs. The following information is

required to create a new user:

 User name

The user name must not exceed 32 characters. It is case-insensitive and

can contain double-byte characters, such as Chinese, Japanese, and Korean

except:

" / \ [ ] : ; | = , + * ? < > ` '

It is recommended to use a password of at least 6 characters.

You can perform the following settings for users:

- 60 -

6.7.2 User Groups

User group is a collection of users with the same access right to files or folders.

GNS-8000B has created the following user groups by default:

 Administrators

All members in this group have administration right. You cannot delete this

group.

 Everyone

All registered users belong to everyone group. You cannot delete this group.

You can manage user groups with the following options:

User groups name must not exceed 256 characters. It is case-insensitive and can

contain double-byte characters, such as Chinese, Japanese, and Korean, except

the following ones:

" / \ [ ] : ; | = , + * ? < > ` '

To properly manage security, it is very important to manage users and user

groups. You may set the share access parameters of each user or user group

accordingly.

- 61 -

Create Users and Assign Users to User Group

The following example demonstrates how to create new users and assign users to

a user group.
