1.5 First Steps
This section provides all the information that you need for a fast operational readiness.
1. Read and observe the security regulations in order to avoid damages to people and
devices; see: 6.
2. Carry out the hardware installation. The hardware installation comprises the connec-
tion of the UTN server to the network, the USB device and the power supply; see:
'Quick Installation Guide'.
3. Make sure that an IP address is stored in the UTN server; see: 7.
4. Install and start the software tool 'SEH UTN Manager' on your Windows client; see:
13.
5. Add the UTN servers that you want to use to the selection list; see: 46.
6. Activate the connection between your client and the USB port to which the USB
device is connected; see: 47.
The connection will be established. The USB device can be used by the client.
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 automatically 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 'InterCon-NetTool'; see: 11.
Different methods for the assignment of the IP address are described in the following.

• ’myUTN Control Center’ 9
•’ARP/PING’9
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.
Note
You can use the domain name service of Bonjour for the name resolution of the IP
address; see: 28.
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: 22.
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: 22.
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.

myUTN User Manual Mac General Information

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 special 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: 24. InterCon-NetTool
The InterCon-NetTool is a software tool developed by SEH Computertechnik 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: 23.

ARP/PING

myUTN User Manual Mac General Information
10
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' command transfers a data
packet containing the IP address to the hardware 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: 23.
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

2.2 Administration via the SEH UTN Manager
Area of
Application
The software tool 'SEH UTN Manager' handles the access of the USB devices. The SEH
UTN Manager shows the availability of all UTN servers and USB devices that exist in the
network and establishes a connection between the client and the USB port of the UTN
server to which the USB device is connected. The software is installed on all clients that
are meant to access a USB device in the network.
Mode of
Operation
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.
After the network scan all UTN servers found – together with the connected USB devices
– will be shown in the 'network list'. The required UTN servers will be selected and added
to the 'selection list'. The devices in the selection list can be configured or connected to
the client.

•Creating a UTN Action:: UTN Actions are small programs used for the automatic
activation and deactivation of port connections. UTN Actions can also automate the
starting and closing of an application in combination with a port connection.
•Additional Tool 'utnm': This tool is used for the activation and deactivation of port
connections. To this purpose, commands are entered and run in the command-line
interface of the operating system. As an alternative, a script will be written.
SEH UTN Manager Versions
The SEH UTN Manager is available in two versions:
• Complete version
•Minimal version (without graphical user interface)
What Are the
Differences
Between the
Versions?
The decisive difference in the complete version is the graphical user interface. It shows
you the program in form of graphic images and offers additional features: searching for
and administrating UTN servers, simplified use of USB devices, and much more.
The minimal version of the SEH UTN Manager can only be used via the command-line
interface and UTN Actions. The minimal version can for example be used to
• provide users with only certain devices with simplified activation/deactivation; see:
’Creating a UTN Action: Automated Port Connections and Program Starts without the
SEH UTN Manager Interface’ 52.
• automate the activation/deactivation of port connections (with scripts); see:
’Additional Tool 'utnm'’ 116.
Note
The complete version is recommended for general use. The minimal version is to be used
by experts only.
In both versions the service 'SEH UTN Service' works in the background and becomes
active after the system start.
Additionally, the following user groups are distinguished:
• users with administrative rights (administrator)
• users without administrative rights (standard user)
The functions Auto-Connect, Auto-Disconnect and Print-On-Demand can only be
configured by users with administrative rights.
