1.1 Product

Purpose

UTN servers comprise USB Deviceservers and USB Dongleservers. As USB Dongleservers, UTN servers make non­network-ready USB dongles accessible via TCP/IP network. The USB dongles are connected to the USB ports of the
UTN server for this purpose. The UTN (UTN = USB to Network) functionality and the corresponding software tool
'SEH UTN Manager' then establish a virtual USB connection between USB dongle and client. The USB dongle can
be used as if it were connected locally.

System Requirements

The UTN server has been designed for use in TCP/IP networks.
The SEH UTN Manager can be used in the following systems:

• Windows 7 or higher, except Windows Server 2008

(For Windows 7 and Windows Server 2008 R2, KB3033929 http://technet.microsoft.com/en-us/library/security/3033929 must be in­stalled.)

• macOS 10.9 or higher

• Linux: *.deb (for Debian-based systems) and *.rpm (for Red Hat-based systems) installation packages are avail­able for 64-bit systems. A successful installation cannot be guaranteed due to the multitude of Linux varieties!
The installation must be carried out on your own.
Installation was tested successfully under the following 64-bit systems:
Debian: Debian 10, Ubuntu 18.04
Red Hat: Red Hat Enterprise Linux 8, Oracle 8, CentOS 8, SUSE Linux Enterprise 15.1, openSUSE Leap 15.1

•IPv4 TCP/IP network

The SEH Product Manager can be used under the following systems:

• Windows 7 or higher

• macOS 10.12.x or higher

•IPv4 TCP/IP network

3.1 How to Configure IPv4 Parameters and DNS

In the hardware installation (  ‘Hardware Installation Guide’) the UTN server is connected to the network. The
UTN server then checks if it receives an IPv4 network configuration (IP address, subnet mask, gateway, DNS - Do­main Name Service) dynamically over DHCP (Dynamic Host Configuration Protocol). If this is not the case, the UTN
server assigns itself an IP address via Zeroconf from the address range which is reserved for Zeroconf (169.254.0.0/

16).

Important:

If the UTN server is connected to an IPv6 network, it will automatically receive an
additional IPv6 address  25.

The IPv4 address assigned to the UTN server can be found via the SEH UTN Manager and SEH Product Manager
software tools. This step usually is carried out during the initial set up (

As an alternative to automatic configuration via DHCP or Zeroconf, you can assign a manual (static) IPv4 network
configuration to the UTN server.

Assigning an IPv4 network configuration using the dongleserver Control Center

 For DHCP: Your network has a DHCP server.
 For DNS: Your network has a DNS server.

1. Start the dongleserver Control Center.

2. Select NETWORK – IPv4.

3. Configure the IPv4 parameters; table 3.1-1 22.

4. Click Save & Restart to confirm.
 The settings will be saved.

Table 3.1-1: IPv4 parameters

Parameters Description

DHCP Enables/disables the DHCP protocol.

If DHCP is enabled in your network, IPv4 network configuration (IP address,
subnet mask, gateway, DNS) is automatic.

We recommend disabling this option once an IP
address has been assigned to the UTN server.

ARP/PING Enables/disables the ARP/PING protocol.

You can use the commands ARP and PING to change an IP address. The imple­mentation depends on your system; read the documentation of your operating
system.

We recommend disabling this option once an IP
address has been assigned to the UTN server.

22

USB Dongleserver User Manual Windows

Parameters Description

IP Address IP address of the UTN server.
Subnet mask Subnet mask of the UTN server.

Subnet masks are used to logically partition big networks into subnetworks. If
you are using the UTN server in a subnetwork, it requires the subnet mask of
the subnetwork.

Gateway IP address of the network's standard gateway which the UTN server uses.

With a gateway, you can address IP addresses from other networks.

DNS Enables/disables the name resolution via a DNS server.

Important:

Only DNS allows you to use host names instead of IP addresses if
you define servers such as e.g. a time server on the UTN server.

Example: Time server configuration ( 36) with
instead of

10.168.0.140.

ntp.server.de

Primary DNS server Defines the IP address of the primary DNS server.
Secondary DNS server Defines the IP address of the secondary DNS server.

The secondary DNS server is used if the first one is not available.

Domain name (suffix) Defines the domain name of an existing DNS server.

3.2 How to Configure IPv6 Parameters

IPv6 (Internet Protocol Version 6) is the successor of the still predominantly used IPv4 (Internet Protocol Version

128

4). IPv6 offers the same basic functions but has many advantages such as the increased address space of 2

32

(IPv6) instead of 2

(IPv4) IP addresses and auto configuration.

Important:

IPv6 address notation differs from IPv4: An IPv6 address consists of 128 bits. The
normal format of an IPv6 address is eight fields. Each field contains four hexadeci­mal digits representing 16 bits.
Example:

2001:db8:4:0:2c0:ebff:fe0f:3b6b

As a URL in a Web browser, an IPv6 address must be enclosed in square brackets.
This prevents port numbers from being mistakenly regarded as part of an IPv6
address.
Example:

http://[2001:db8:4:0:2c0:ebff:fe0f:3b6b]:443

The URL will only be accepted by browsers that support IPv6.

You can embed the UTN server into an IPv6 network.

WAR NIN G

UTN functionality ( 2) and the corresponding SEH UTN Manager only work in
IPv4 networks. The SEH Product Manager also only works in IPv4 networks.

In pure IPv6 networks, it is only possible to access the dongleserver Control Center
( 10) to administer the UTN server.

The UTN server will automatically receive one or more IPv6 addresses in addition to its IPv4 address. To optimally
embed the UTN into your network, you can configure IPv6 parameters.

1. Start the dongleserver Control Center.

2. Select NETWORK – IPv6.

3. Configure the IPv6 parameters; table 3.2-1 25.

4. Click Save & Restart to confirm.
 The settings will be saved.

Table 3.2-1: IPv6 parameters

Parameters Description

IPv6 Enables/disables the IPv6 functionality of the UTN server.
Automatic configuration Enables/disables the automatic assignment of the IPv6 address to the UTN

server.

IPv6 address Defines an IPv6 unicast address in the format n:n:n:n:n:n:n:n which is manually

assigned to the UTN server.

• Every 'n' represents the hexadecimal value of one of the eight 16 bit ele­ments of the address.

• Leading zeros can be omitted.

• An IPv6 address may be entered or displayed using a shortened version
when successive fields contain all zeros (0). In this case, two colons (::) are
used.

Router Manually defines a static router to which the UTN server sends its requests.

25

USB Dongleserver User Manual Windows

Parameters Description

Prefix length Defines the length of the subnet prefix for the IPv6 address. The value 64 is pre-

set.
Address ranges (e.g. your network) are specified with prefixes. To do this, the

prefix length (number of bits used) is added to the IPv6 address as a decimal
number and the decimal number is preceded by '/'.
