1.1 myUTN
Purpose myUTN allows you to access non-network-ready USB devices (e.g.
hard disks, printers, etc.) in the network. The USB devices will be
connected to the USB port of the UTN server.
The 'Dongleservers' (myUTN-80 and myUTN-800) are exclusively
designed for the deployment of USB dongles.
The software tool 'SEH UTN Manager' handles the access of the USB
devices. The software is installed on all clients that are meant to
access a USB device in the network. The SEH UTN Manager shows
the availability of all UTN servers in the network and establishes a
connection between the client and the USB port including the con-
nected USB device.
System
Requirements
myUTN has been designed for the use in TCP/IP-based networks. The
SEH UTN Manager has been designed for the use in the following
systems:
• Windows XP or later

This chapter contains information concerning the
device and the documentation as well as notes about
your safety.
You will learn how to benefit from your UTN server and
how to operate the device properly.

mation about the usage in other environments can be found in the
relevant system-specific User Manual. For further information; see:
’Documentation’ 8.
Procedure and Basic
Functions
After the SEH UTN Manager is started, the network will be scanned
for connected UTN servers. The network range to be scanned is
freely definable.
All UTN servers found will be shown in the 'network list' together
with the connected USB devices. The required UTN servers will be
selected and added to the 'selection list'. The UTN servers listed in
the selection list can then be used by the user. To use a USB device,
the user establishes a connection between the client and the USB
port of the UTN server to which the USB device is connected.

1.6 Saving the IP Address in the UTN Server
Why IP Addresses? An IP address is used to address network devices in an IP network.
TCP/IP network protocols require the storing of the IP address in the
UTN server so that the device can be addressed within the network.
How Does the UTN
Server Obtain IP
Addresses?
The UTN server is able to assign itself an IP address during the initial
installation. Boot protocols are used to assign an IP address auto-
matically to the UTN server. Upon delivery, the boot protocols
'BOOTP' and 'DHCP' are enabled.
Once the UTN server is connected to the network, it checks whether
an IP address can be obtained from the boot protocols BOOTP or
DHCP. If this is not the case, the UTN server assigns itself an IP
address from the address range (169.254.0.0/16) which is reserved
for ZeroConf.
Once the UTN server has automatically received an IP address via a
boot protocol, you can save a freely definable IP address in the UTN
server. The UTN server’s assigned IP address can be determined and
changed using the software tools 'SEH UTN Manager' and 'Inter-
Con-NetTool'; see: 18.
Different methods for the assignment of the IP address are described
in the following.
Automatic Methods

• ’ARP/PING’ 17

General Information
myUTN User Manual Windows 15
ZeroConf
If no IP address can be assigned via boot protocols, the UTN server
assigns itself an IP address via ZeroConf. For this purpose, the UTN
server picks an IP address at random from the address range
(169.254.0.0/16) which is reserved for ZeroConf.
You can use the domain name service of Bonjour for the name reso-
lution of the IP address; see: 42.
BOOTP
The UTN server supports BOOTP, which means that the IP address of
the UTN server can be assigned via a BOOTP server.
Requirements The 'BOOTP' parameter has been enabled, see: 35.
A BOOTP server is available in the network.
If the UTN server is connected, it asks the BOOTP host for the IP
address and the host name. The BOOTP host answers and sends a
data packet containing the IP address. The IP address is saved in the
UTN server.
DHCP
The UTN server supports DHCP, which means that the IP address of
the UTN server can be assigned dynamically via a DHCP server.
Requirements The 'DHCP' parameter has been enabled, see: 35.
A DHCP server is available in the network.
After the hardware installation, the UTN server asks a DHCP server
for an IP address by means of a broadcast query. The DHCP server
identifies the UTN server on the basis of its hardware address and
sends a data packet to the UTN server.
This data packet contains, among others, the IP address of the UTN
server, the default gateway, and the IP address of the DNS server.
The data is saved in the UTN server.

General Information
myUTN User Manual Windows 16
Auto Configuration (IPv6 Standard)
The UTN server can have an IPv4 address and several IPv6 addresses
at the same time. The IPv6 standard is used to automatically assign
IP addresses in IPv6 networks. When connected to an IPv6 network,
the UTN server will automatically obtain an additional 'link-local' IP
address from the IPv6 address range.
The UTN server uses the 'link-local' IP address to search for a router.
The UTN server sends so-called 'router solicitations' (RS) to the spe-
cial multicast address FF02::2. The available router will then return a
'Router Advertisement' (RA) containing the required information.
With a prefix from the range of the global unicast addresses, the
UTN server can compose its own address. It simply replaces the first
64 bits (prefix FE80::) with the prefix that was sent in the RA.
Requirements The 'IPv6' parameter has been activated.
The 'Automatic configuration' parameter has been activated.
To configure the assignment of IPv6 addresses, see: 38.
InterCon-NetTool
The InterCon-NetTool is a software tool developed by SEH Comput-
ertechnik GmbH for the administration ofSEH network devices. The
IP Wizard of the InterCon-NetTool helps you to configure the TCP/IP
parameters, e.g. the IP address. You can manually enter the desired
IPv4 address and save it in the UTN server using the IP Wizard. To
configure an IPv4 address via the InterCon-NetTool, see: 37.
SEH UTN Manager
You can manually enter the desired IPv4 address and save it in the
UTN server using the SEH UTN Manager. To configure an IPv4 address
via the SEH UTN Manager, see: 36 .
myUTN Control Center
You can manually enter the desired IP address and save it in the UTN
server using the myUTN Control Center.

General Information
myUTN User Manual Windows 17
• To configure an IPv4 address via the myUTN Control Center, see:
36.
• To configure an IPv6 address via the myUTN Control Center, see:
38.
ARP/PING
The assignment of the IP address to the hardware address can be
done via the ARP table. The ARP table is an internal system file in
which the assignment is temporarily saved (about 15 min). This table
is administered by the ARP protocol.
By means of the 'arp' and 'ping' commands, you can save the IP
address in the UTN server. If the UTN server already has an IP
address, the 'arp' and 'ping' commands cannot be used to save a new
IP address.
However, an IP address from the address range (169.254.0.0/16)
which is reserved for ZeroConf can be overwritten by means of the
'arp' and 'ping' commands.
The 'arp' command is used for editing the ARP table. The 'ping' com-
mand transfers a data packet containing the IP address to the hard-
ware address of the UTN server. If the data packet has been
successfully sent and received, the UTN server permanently saves the
IP address.
The implementation of the 'arp' and 'ping' command depends on the
system used. Read the documentation for your operating system.
Requirements The 'ARP/PING' parameter has been enabled, see: 36.
Edit the ARP table:
Syntax: arp -s <IP address> <hardware address>
Example: arp -s 192.168.0.123 00-c0-eb-00-01-ff
Assign a new IP address to the UTN server:
Syntax: ping <IP address>
Example: ping 192.168.0.123
