General Information

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: Ö17.
Different methods for the assignment of the IP address are described
in the following.

myUTN User Manual

General Information
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
resolution of the IP address; see: Ö42.
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: Ö35.
; 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: Ö35.
; 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

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: Ö38.
InterCon-NetTool
The InterCon-NetTool has been developed by SEH Computertechnik
GmbH for the administration of SEH 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: Ö37.
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: Ö36.

General Information
myUTN Control Center
You can manually enter the desired IP address and save it in the UTN
server using the myUTN Control Center.
• To configure an IPv4 address via the myUTN Control Center, see:
Ö36.
• To configure an IPv6 address via the myUTN Control Center, see:
Ö38.
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'
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: Ö36.
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

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 device. The software is
installed on all clients that are meant to access a USB device in the
network.
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.
After the network scan all UTN servers found – together with the
connected devices – will be shown in the 'network list'. The preferred
devices will be selected and added to the 'selection list'. The devices
in the selection list can be configured or connected to the client.
Automatisms
The SEH UTN Manager supports, among other things, the following
automatisms:
• Autostart: Upon booting the user’s computer the SEH UTN
Manager is activated.
• Auto-Connect: This functionality allows for the automatic
activation of a device connection after the launch of the SEH
UTN Manager.
• Auto-Disconnect: This functionality allows for the automatic
deactivation of a device connection after a time defined.
• Print-On-Demand: A connection between the USB device
(printer or MFP) and the client will be automatically created as
soon as a print job is received. After completion of the print job,
the connection will be automatically disabled.
• Creating a UTN Action: UTN Actions are small programs used for
the automatic activation and deactivation of device
connections. UTN Actions can also automate the starting and
myUTN User Manual

Administration Methods
closing of an application in combination with a device
connection.
• Additional tool 'utnm': This tool is used for the activation and
deactivation of USB devices. 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 be used to
• provide users with only certain devices with simplified
activation/deactivation; see: ’Creating a UTN Action: Automated
Device Connections and Program Starts without the SEH UTN
Manager Interface’ Ö70.
• automate the activation/deactivation of USB devices (with
scripts); see: ’Additional Tool 'utnm'’ Ö140.
For general use the complete version is recommended. The minimal
version is only to be used by experts.
In both versions the service 'SEH UTN Service' works in the
background and becomes active after the system start. The service
can be controlled by means of the usual administration methods.
Additionally, the following user groups are distinguished:

How to Configure IPv6 Parameters
You can integrate the UTN server into an IPv6 network.
What are the
Advantages of IPv6?
IPv6 (Internet Protocol version 6) is the successor of the more
common IPv4. Both protocols are standards for the network layer of
the OSI model and regulate the addressing and routing of data
packets via a network. The introduction of IPv6 has many benefits:
• IPv6 increases the IP address space from 232 (IPv4) to 2128 (IPv6)
IP addresses.
• Auto Configuration and Renumbering
• Efficiency increase during routing due to reduced header
information.
• Integrated services such as IPSec, QoS, Multicast
• Mobile IP
What is the Structure
of an IPv6 Address?
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.
Each field is separated by a colon (:).
Example: fe80 : 0000 : 0000 : 0000 : 0000 : 10 : 1000 : 1a4
Leading zeros in a field can be omitted.
Example: fe80 :
0 :
0 :
0 :
0 : 10 : 1000 : 1a4
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. However, the use of two colons can be used only
once in an address.
Example: fe80 :
: 10 : 1000 : 1a4
As a URL in a Web browser, an IPv6 address must be enclosed in
brackets. This prevents port numbers from being mistakenly
regarded as part of an IPv6 address.
Example: http://[2001:608:af:1::100]:443
myUTN User Manual
38
Network Settings
The URL will only be accepted by browsers that support IPv6.
Which Types of IPv6
Addresses are
available?
There are different types of IPv6 addresses. The prefixes of the IPv6
addresses provide information about the IPv6 address types.
• Unicast addresses can be routed globally. These addresses are
unique and therefore unambiguous. A packet that is sent to a
unicast address will only arrive to the interface that is assigned
to this address. Unicast addresses have the prefixes '2' or '3'.
• Anycast addresses are assigned to more than one interface. This
means that a data packet that is sent to this address will arrive
at various devices. The syntax of anycast addresses is the same as
the one of unicast addresses. The difference is that anycast
addresses choose one interface out of many.
A packet that is dedicated to an anycast address arrives at the
nearest interface (in line with the router metrics). Anycast
addresses are only used by routers.
• Multicast addresses allow you to send data packets to different
interfaces at the same time without a proportional increase of
the bandwidth. A multicast address can be recognized by the
prefix 'ff'.

IPv6 address
Defines a UTN server IPv6 unicast address assigned
manually in the format n:n:n:n:n:n:n:n.
Every 'n' represents the hexadecimal value of one of the
eight 16 bit elements of the address. 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
Defines the IPv6 unicast address of the router. The UTN
server sends its 'Router Solicitations' (RS) to this router.
Prefix length
Defines the length of the subnet prefix for the IPv6
address. The value 64 is preset.
Address ranges are indicated by prefixes. The prefix
length (number of bits used) is added to the IPv6
address and specified as a decimal number. The decimal
number is separated by '/'.
3.3
How to Configure the DNS
DNS is a service that translates domain names into IP addresses.
Using DNS, names can be assigned to IP addresses and vice versa. If a
DNS server is available in your network, you can use DNS for your
UTN server.
If you use a domain name during the configuration process, you
must first enable and configure DNS. DNS is used for the
configuration of the time server, for example.

How to Configure SNMP
SNMP (Simple Network Management Protocol) has become the
standard protocol for the administration and monitoring of network
elements. The protocol controls communication between the
monitored devices and the monitoring station.
SNMP allows you to read and edit management information
provided by the network elements (e.g. UTN server). The UTN server
supports versions 1 and 3 of SNMP.
SNMPv1
The SNMP community is a basic form of access protection. A large
number of SNMP managers are grouped together in the community.
The community is then assigned (read/write) access rights. The
general community string is 'public'.
The community string for SNMPv1 is transferred in plain text and
does not provide sufficient protection.
SNMPv3

How to Configure Bonjour
Bonjour allows the automatic recognition of computers, devices,
and network services in TCP/IP-based networks.
The UTN server uses the following Bonjour functions:
• Checking the IP address assigned via ZeroConf
• Assignment of host names to IP addresses
• Location of server services without knowledge of the device’s
host name or IP address.
myUTN User Manual
42
Network Settings
When checking the IP address assigned via ZeroConf (see: ’ZeroConf’
Ö14) the UTN server sends a query to the network. If the IP
address has already been assigned elsewhere in the network, the
UTN server will receive a message. The UTN server then sends
another query with a different IP address. If the IP address is
available, it is saved in the UTN server.
The domain name service is used for additional Bonjour features.
Since there is no central DNS server in Bonjour networks, each
device and application has its own small DNS server.
This integrated DNS server (mDNS) collects and administers the
information of all participants in the net. In addition to the features
of a classical DNS server, the mDNS server also saves the IP address,
the service name and the offered services of each participant.

How to Configure POP3 and SMTP (only
myUTN-80 and later)
You must configure the protocols POP3 and SMTP on the UTN server
so that the notification service (Ö57) and the remote
maintenance via email (Ö31) will work properly.
POP3
'POP3' (Post Office Protocol Version 3) is a transfer protocol that a
client can use to fetch emails from a mail server. POP3 is required to
administer the UTN server via email.
SMTP
'SMTP' (Simple Mail Transfer Protocol) is a protocol that controls the
sending of emails in networks. SMTP is required to administer the
UTN server via email and to run the notification service.

How to Configure WLAN (myUTN-54 only)
The UTN server model 'myUTN-54' can handle WLAN. This allows you
to wirelessly operate the UTN server in the network.
What is WLAN?
WLAN is a radio technology that allows you to establish wireless
connections between network components. The WLAN technology is
defined as a standard of the IEEE 802.11 family. The myUTN-54
supports the standards IEEE 802.11b, IEEE 802.11g and IEEE 802.11n.
To make use of the radio technology the myUTN-54 has additional
parameters Ö50. You can view the current WLAN settings in the
myUTN Control Center under the menu item NETWORK - WLAN.
Connection Status
The following icons in the myUTN Control Center indicate the
current connection status:
UTN server in the wireless network
UTN server in the wired network
WLAN Security
Make sure that no unauthorized user logs on to the Wireless LAN
and that no one has access to the Internet or network resources.
Your UTN server offers several security mechanisms.

Network Settings
WEP
WEP (Wired Equivalent Privacy) is an encryption method according to
IEEE 802.11 on the basis of the RC4 encryption algorithm. WEP offers
mechanisms for data encryption and authentication. WEP uses a key
to encrypt the entire communication. As for encrypted access points,
the same WEP key must be used for the access point and the UTN
server.
Some access points convert WEP keys that are entered as ASCII text
into arbitrary hexadecimal values. In this case, the WEP keys for the
access point and the UTN server do not match. It is therefore
recommended to use hexadecimal WEP keys.
WPA/WPA2
In contrast to WEP, WPA (Wi-Fi Protected Access) offers enhanced
mechanisms for exchanging keys. The exchange key is only used at
the beginning of a session. Afterwards a session key is used. The key
is regenerated periodically. The WPA mechanism requires an
authentication at the beginning of a connection.
In the 'Personal Mode' authentication is done via the Pre Shared Key
(PSK). The PSK is a password with 8–63 alphanumerical characters.
The 'Enterprise Mode' uses the EAP authentication method.
An individual 128 bit key is used for data encryption after the
authentication. The encryption methods TKIP (Temporal Key
Integrity Protocol) and AES (Advanced Encryption Standard) are
available for the encryption of data.
Authentication
What Do You Want
to Do?
You can check the identity of a device or user by means of an
authentication method before they gain access to resources in the
network. The UTN server offers different variants of EAP (Extensible
Authentication Protocol) as authentication method. For further
information; see: ’How to Use Authentication Methods’ Ö96.

Description
Mode
(Communication Mode)
Defines the communication mode. The communication
mode defines the network structure in which the UTN
server will be installed. Two modes are available:
- In the 'Ad-Hoc' mode, the UTN server communicates
directly with another WLAN client (peer-to-peer).
- The 'infrastructure' mode is suitable for setting up large
wireless networks with several devices in different
rooms. Communication between the devices is done via
an access point which is connected to the network. The
access point can be protected by encryption or
authentication.
Network name
(SSID)
Defines the SSID. The ID of a wireless network is
referred to as SSID (Service Set Identifier) or network
name. Each wireless LAN has a configurable SSID in
order to clearly identify the wireless network. The SSID is
configured in the access point of a Wireless LAN. Each
device (PC, UTN server, etc.) that is intended to have
access to the wireless network must be configured using
the same SSID.
Roaming
Enables/disables the use of roaming. Roaming refers to
the 'moving' of one radio cell to the next. The UTN server
will use the access point that has the strongest signal. If
the UTN server moves towards the sphere of another
access point, the UTN server switches automatically and
without loss of connection to the next radio cell. The
parameter 'Roaming' can only be configured in the
'Infrastructure' mode.
Roaming level
The transmission power of the UTN server can be
defined using the parameter 'Roaming level'. The value
65 -dbm is preset. The parameter 'Roaming level' can
only be configured in the 'Infrastructure' mode.

Parameters
Description
Channel
(Frequency Range)
Defines the channel (frequency range) on which the
entire data communication will be transmitted. The
product uses the 2.4 GHz ISM band. A channel has a
bandwidth of 22 MHz. The distance between two
neighboring channels is 5 MHz. Channel 3 is preset. The
parameter 'Channel' can only be configured in the
'Ad-Hoc' mode.
Neighboring channels overlap, which can lead to
interferences. If several WLANs are operated in a small
radius, a distance of at least five channels should exist
between two channels.
Keep yourself informed about national provisions
regarding the use of WLAN products and only use
authorized channels.

device that reads the actual time from a reference clock and
distributes this information to its clients. In the UTN server, the time
server is defined via the IP address or the host name.
UTC
The UTN server uses 'UTC' (Universal Time Coordinated) as a basis.
UTC is a reference time and used as a time standard.
Time Zone
The time received by the time server does not necessarily correspond
to your local time zone. Deviations from your location and the
resulting time difference (including country-specific particularities
such as Daylight Saving Time) can be handled by means of the 'Time

How to Control the Access to Dongle-Protected
Software (only myUTN-80) or USB Devices (only
myUTN-150) via VLAN
The UTN server supports the use of VLAN (Virtual Local Area
Network). It is useful to divide a physical network into VLANs for
performance and security reasons.
If a VLAN spans multiple switches, you can use so-called VLAN
trunks (VLT). A VLT is used to forward data from different VLANs via
a single connection. Both individual ports and bundled ports can be
used.
The UTN server supports the forwarding of VLAN data via its USB
ports. To do this, the VLANs must be known to the UTN server. After
this, the USB ports used for the forwarding of the data must be
linked to the specified VLANs.
Benefits and
Purpose
The VLANs can be used to control the access to dongle-protected
software (myUTN-80) or USB devices (myUTN-150). This way, a
specified group of network participants can be provided with a
certain amount of dongle-protected software licenses or USB
devices.
Example
6 engineers have access
to 3 dongle-protected CAD
software licenses.
3 accountants have access
to one dongle-protected
accounting software.
The
access
by
a
participant to software that
is not intended for this
participant is excluded.
Note: A USB port can be
connected with only one
participant at a time.

Creating a UTN Action: Automated Device Connections and
Program Starts without the SEH UTN Manager Interface
You can create UTN actions. UTN Actions are small programs used
for the automatic activation and deactivation of device connections.
UTN Actions can also automate the starting and closing of an
application in combination with a device connection.
The process defined in the UTN action will run automatically after
the execution of the file. Since the 'SEH UTN Service' is active in the
background, the user is not required to start the SEH UTN Manager
interface. I.e., UTN Actions can be used with the complete and
minimal version.
A wizard within the SEH UTN Manager will guide you through the
process of creating a UTN Action. The following UTN Actions can be
created:
• UTN Actions which activate and deactivate the device
The wizard will automatically create one UTN Action for the activation and one UTN Action for
the deactivation of the device. Both UTN Actions will be saved to the desktop.
• UTN Action which starts an application and activates the
device
After the selection of an application by the user, the wizard will automatically create an action
which starts an application and activates the device. Additionally, you can specify a device
deactivation after the closing of the application.
• Custom UTN Action (Experts only)
With the help of the wizard, a custom UTN Action can be created. You can create:
- UTN Actions which activate and deactivate the device. You can define additional options.
- A script for the start of the application and activation of the device. Additionally, you can
specify a delay for the start of the application, the deactivation of the device after the closing of
the application and additional options. The script will be created automatically and can then be
edited. Finally, the complete UTN Action will be created automatically by the SEH UTN Manager
and saved by the user.

What Are Selection
Lists?
How to Manage Selection Lists for Several
Participants
The selection list is a central element of the SEH UTN Manager. It
displays all embedded UTN servers as well as the connected USB
devices and shows their status. The displayed USB devices can be
connected to the client and can be used. The selection list can be
edited and configured according to your needs by adding und
deleting the required devices.
Selection lists are saved as 'SEH UTN Manager .ini' files.
Two selection list types are available:
• global selection list
• user-specific selection list
Benefits and
Purpose
By means of the selection list type in combination with the user
management, the administrator can control the access to the UTN
servers that are available in the network:
All users will at first use the same global selection list.
Alternatively, each user can use a user-specific selection list. The
access can be controlled by placing predefined selection lists into
user-specific directories. Revoking write rights to the .ini file will
limit and control the access to functions of the SEH UTN Manager
for individual users.
In the following, the selection list types will be described in greater
detail.

How to Define the Encryption Level for SSL/TLS
Connections
The following connections on the UTN server can be encrypted via
SSL/TLS:
• Email: POP3 (Ö44)
• Email: SMTP (Ö44)
• Web access to the myUTN Control Center: HTTPS (Ö82)
• Data transfer between the clients and the UTN server (and the
connected USB devices): USB port (Ö103)
Encryption Level
The encryption strength and thus the safety of the connection is
defined via the encryption level.
Cipher Suite
Each encryption level is a collection of so-called cipher suites. A
cipher suite is a standardized sequence of four cryptographic
algorithms that are used to establish a secure connection.
Depending on their cipher strength (in bit), cipher suites are grouped
to form an encryption level. Which cipher suites are supported by
the UTN server, i.e. are part of an encryption level, depends on the
protocol used (SSLv2, SSLv3, TLSv1).
Establishing
Connections
When establishing a secure connection, a list of supported cipher
suites is sent to the communicating party. A cipher suite is agreed
upon that will be used later on. The strongest cipher suite that is
supported by both parties will be used by default. If there is no
cipher suite that is supported by both parties, no SSL/TLS connection
will be established.
The communicating parties of the UTN server (e.g. browser) must
support the cipher suites of the selected encryption level in order
to successfully establish a connection. When problems occur,
select a different level or reset the parameters of the UTN server;
see: Ö107.
myUTN User Manual
80
Security
The following encryption levels can be selected:
• Compatible: Cipher suites with an encryption of 40 to 256 bit
will be used.
• Low: Only cipher suites with a low encryption of 56 bit will be
used. (Fast connection)
• Medium: Only cipher suites with an encryption of 128 bit will be
used.
• High: Only cipher suites with a strong encryption of 128 to 256
bit will be used. (Slow connection)

If HTTPS is exclusively chosen as the connection type, the
administrative web access to the myUTN Control Center is protected via
SSL/TLS. The cipher strength is defined via the encryption level Ö80.
SSL/TLS requires a certificate to check the identity of the UTN server.
During a so-called 'handshake', the client asks for a certificate via a
browser. This certificate must be accepted by the browser. Please
refer to the documentation of your browser software. URLs that
require an SSL/TLS connection start with 'https'.

How to Control Access to the UTN Server (TCP
Port Access Control)
TCP
Port Access Control
You can control the access to the UTN server. To do so, various TCP
port types on the UTN server can be locked. Network elements that
have permission to access the UTN server, can be defined as
exceptions and excluded from locking. The UTN server only accepts
data packets from network elements defined as exceptions.
Security Levels
The port types to be locked must be defined in the 'Security level'
area. The following categorization can be selected:
• Lock UTN access (locks UTN ports)
• Lock TCP access (locks TCP ports: HTTP/HTTPS/UTN)
• Lock all (locks IP ports)
Exceptions
In order to exclude network elements (e.g. clients, DNS server, SNTP
server) from port locking, they must be defined as exceptions. To do so,
the access-authorized network elements’ IP addresses or MAC
addresses (hardware addresses) must be entered in the 'Exceptions'
area. Please note:
• MAC addresses are not delivered through routers!
• The use of wildcards (*) allows you to define subnetworks.

How to Control Access to USB Devices (only
myUTN-80 and later)
Via the USB ports you can control the access to the USB devices that
are connected to the UTN server. Two security methods are available
for each USB port. Both security methods can also be used in
combination.
USB Port Key Control
In the course of the key control a key is specified for the USB port
via the myUTN Control Center. By entering the key, the USB device
that is connected to the USB port is protected against unwanted
access.
The USB device will no longer be shown in the SEH UTN Manager.
This means that a user will not be able to make changes to the USB
device or to establish a connection between the client and the USB
device.
To make the USB device available, the user must enter the key for
the USB port on the client. This is done via the SEH UTN Manager. By
changing the key in the myUTN Control Center the user can (once
again) lose its permission to access the USB device.
USB Port Device
Assignment
Device assignment means that a USB device is permanently assigned
to each USB port via the myUTN Control Center. A USB device can
then only be operated together with its assigned USB port.
The device assignment makes sure that the (security) settings of the
USB port and the USB device are not bypassed. If a device other
than the assigned USB device is connected to the USB port, it
cannot be operated.

How to Use Certificates Correctly
The UTN server has its own certificate management. This section
explains how certificates are used and when the use of certificates is
recommended.
What Are
Certificates?
Certificates can be used in TCP/IP-based networks to encrypt data
and to authenticate communication partners. Certificates are
electronic messages containing a key (public key) and a signature.
Benefits and
Purpose
The use of certificates allows for various security mechanisms. Use
certificates in your UTN server
• to check the identity of the UTN server in the network; see:
’Configuring EAP-TLS’ Ö98.
• to authenticate the UTN server/client if the administrative access
to the myUTN Control Center is protected via HTTPS (SSL/TLS).
If you want to use certificates, it is advisable to protect the
administrative access to the myUTN Control Center by a password so
that certificates on the UTN server cannot be deleted by
unauthorized persons; see: Ö83.
Which Certificates
Are available?
Both self-signed certificates and CA certificates can be used with
the UTN server. The following certificates can be distinguished:
• Upon delivery, a self-signed certificate (the so-called default
certificate) is stored in the UTN server. It is recommended that
you replace the default certificate by a self-signed certificate or
CA certificate as soon as possible.
• Self-signed certificates have a digital signature that has been
created by the UTN server.
• CA certificates are certificates that have been signed by a
certification authority (CA).
• The authenticity of the CA certificate can be verified by means
of a so-called root certificate issued by the certification
myUTN User Manual
89
Security
authority. The root certificate is stored on an authentication
server in the network.
• S/MIME certificates (*.pem file) are used to sign and encrypt the
emails that are sent by the UTN server. The corresponding private
key must be installed as an own certificate in the PKCS#12
format (as *.p12 file) in the intended email program (Mozilla
Thunderbird, Microsoft Outlook, etc.). Only then can the emails
be verified and displayed (in the case of encryption).
(only myUTN-80 and later)
The following certificates can be installed at the same time in the UTN
server:
- 1 Self-signed certificate
- 1 CA certificate or PKCS#12 certificate
- 1 Root certificate
- 1 S/MIME certificate (only myUTN-80 and later)
You can also generate a certificate request for a CA certificate. All
certificates can be deleted separately. Existing certificates will be
overridden when installing or generating new certificates.
A PKCS#12 certificate can only be installed if there are currently no
certificate requests or CA certificates installed.

How to Use Authentication Methods
By means of an authentication, a network can be protected against
unauthorized access. The UTN server can participate in various
authentication procedures. This section describes which procedures
are supported and how these procedures are configured on the UTN
server.
What Is IEEE 802.1x?
The IEEE 802.1x standard provides a basic structure for various
authentication and key management protocols. IEEE 802.1x allows
you to control the access to networks. Before users gain access to a
network via a network device, they must authenticate themselves in
the network. After the authentication was successful, the access to
the network will be freed.
What Is EAP?
The standard IEEE 802.1x is based upon the EAP (Extensible
Authentication Protocol). EAP is a universal protocol for many
authentication procedures. EAP allows for a standardized
authentication procedure between the network device and an
authentication server (RADIUS). First you must define the
authentication procedure (TLS, PEAP, TTLS, etc.) to be used and
configure it on all network devices involved.
What Is RADIUS?
RADIUS (Remote Authentication Dial-In User Service) is an
authentication and account management system that validates user
login information and grants access to the desired resources.
The UTN server supports various EAP authentication methods in
order to authenticate itself in a protected network.

Configuring EAP-MD5
Benefits and
Purpose
EAP-MD5 validates the identity of devices or users before they gain
access to network resources. You can configure the UTN server for
the EAP-MD5 network authentication. This ensures that the UTN
server gets access to protected networks.
Basic Functions
EAP-MD5 describes a user-based authentication method via a
RADIUS server. The UTN server must be defined as user (with user
name and password) on a RADIUS server. The authentication method
EAP-MD5 must then be enabled on the UTN server and the user
name and password need to be entered.
Requirements
; The UTN server is defined as user (with user name and password)
on a RADIUS server.

97
Security
Configuring EAP-TLS
Benefits and
Purpose
EAP-TLS (Transport Layer Security) validates the identity of devices
or users before they gain access to network resources. You can
configure the UTN server for the EAP-TLS network authentication.
This makes sure that the UTN server gets access to protected
networks.
Basic Functions
EAP-TLS describes a certificate-based authentication method via a
RADIUS server. For this purpose, certificates are exchanged between
the UTN server and the RADIUS server. An encrypted TLS connection
between the UTN server and the RADIUS server is established in this
process. Both RADIUS server and UTN server need a valid, digital
certificate signed by a CA. The RADIUS server and the UTN server
must validate the certificate. After the mutual authentication was
successful, the access to the network will be freed.
Since each device needs a certificate, a PKI (Public Key
Infrastructure) must be available. User passwords are not necessary.
If you want to use the EAP-TLS authentication, you must observe
the instructions below in the indicated order. If this procedure is not
adhered to, the UTN server in the network may not be addressable.
In this case you have to reset the parameters of the UTN server; see:
Ö107.
Procedure
• Create a certificate request on the UTN server; see: Ö92.
• Create a CA certificate using the certificate request and the
authentication server.
• Install the CA certificate on the UTN server; see: ’Saving the CA
Certificate in the UTN Server’ Ö93.
• Install the root certificate of the authentication server on the
UTN server; see: ’Saving the Root Certificate in the UTN Server’
Ö94.
• Enable the authentication method 'EAP-TLS' on the UTN server.

Configuring EAP-TTLS
Benefits and
Purpose
Basic Functions
EAP-TTLS (Tunneled Transport Layer Security) validates the identity
of devices or users before they gain access to network resources. You
can configure the UTN server for the EAP-TTLS network
authentication. This ensures that the UTN server gets access to
protected networks.
EAP-TTLS consists of two phases:
• In phase 1, a TLS-encrypted channel between the UTN server and
the RADIUS server will be established. Only the RADIUS server
authenticates itself using a certificate that was signed by a CA.
This process is also referred to as 'outer authentication'.
• In phase 2, an additional authentication method is used for the
communication within the TLS channel. EAP-defined methods
and older methods (CHAP, PAP, MS-CHAP und MS-CHAPv2) are
supported. This process is also referred to as 'inner
authentication'.
The advantage of this procedure is that only the RADIUS server
needs a certificate. Therefore no PKI is needed. Moreover, TTLS
supports most authentication protocols.
Requirements
; The UTN server is defined as user (with user name and password)
on a RADIUS server.
Proceed as follows:
1. Start the myUTN Control Center.
2. Select SECURITY – Authentication.

TLS channel.
6. To make the connection more secure, you can also install the
root certificate of the RADIUS server on the UTN server (Ö94).
7. Click Save & Restart to confirm.
ª The settings are saved.
Configuring PEAP
Benefits and
Purpose
PEAP (Protected Extensible Authentication Protocol) validates the
identity of devices or users before they gain access to network
resources. You can configure the UTN server for the PEAP network
authentication. This ensures that the UTN server gets access to
protected networks.
Basic Functions
In the case of PEAP (compare EAP-TTLS, see Ö99), an encrypted
TLS (Transport Layer Security) channel is established between the
UTN server and the RADIUS server. Only the RADIUS server
authenticates itself using a certificate that was signed by a CA.
The TLS channel is then used to establish another connection that
can be protected by means of additional EAP authentication
methods (e.g. MSCHAPv2).
The advantage of this procedure is that only the RADIUS server
needs a certificate. Therefore no PKI is needed. PEAP uses the
advantages of TLS and supports various authentication methods,
including user passwords and one-time passwords.
Requirements
; The UTN server is defined as user (with user name and password)
on a RADIUS server.
Proceed as follows:
1. Start the myUTN Control Center.
2. Select SECURITY – Authentication.

6. To make the connection more secure, you can also install the
root certificate (Ö94) of the RADIUS server on the UTN server.
7. Click Save & Restart to confirm.
ª The settings are saved.
Configuring EAP-FAST
Benefits and
Purpose
EAP-FAST (Flexible Authentication via Secure Tunneling) validates
the identity of devices or users before they gain access to network
resources. You can configure the UTN server for the EAP-FAST
network authentication. This ensures that the UTN server gets access
to protected networks.
Basic Functions
EAP-FAST uses (as in the case of EAP-TTLS, see Ö99) a channel in
order to protect the data transfer. The main difference is that
EAP-FAST does not require certificates for authentication purposes.
(The use of certificates is optional).
PACs (Protected Access Credentials) are used to build the channel.
PACs are credentials that comprise up to three components.
• A shared secret key that contains the preshared key between the
UTN server and the RADIUS server.
• An opaque part that is provided to the UTN server and presented
to the RADIUS server when the UTN server wishes to obtain
access to network resources.
• Other information that may be useful to the client. (Optional)
EAP-FAST uses two methods to generate PACs:
myUTN User Manual
101
Security
• The manual delivery mechanism can be every mechanism that
the administrator configures and considers to be safe for the
network.
• In the case of the automatic delivery, an encrypted channel is
established in order to protect the UTN server authentication as
well as the delivery of the PACs.

The IP address is the unique address of each node in a network, i.e.
an IP address may occur only once on a local network. The system
administrator usually assigns the IP address. The address must be
saved in the UTN server to make sure that it can be addressed within
the network.

Appendix - Glossary
Host Name
The host name is an alias for an IP address. The host name uniquely
identifies the UTN server in the network and makes it easier to
remember.
Gateway
Using a gateway, you can address IP addresses from external
networks. If you want to use a gateway, you can configure the
relevant parameter in the UTN server via the myUTN Control Center.
Subnet Mask
With the help of the subnet mask, large networks can be split up
into subnetworks. In this case, the user IDs of the IP addresses are
assigned to the various subnetworks. The UTN server is configured
not to use subnetworks by default. If you want to use a subnetwork,
you can configure the relevant parameter in the UTN server via the
myUTN Control Center.
Default Name
The default name of the UTN server is made up of the two letters 'IC'
and the device number. The device number consists of the last six
numbers of its hardware address.
Default name
IC0001ff
Device number
The default name can be found in the myUTN Control Center or in
the InterCon-NetTool.

SEH UTN Manager - Function Overview
Functions in the SEH UTN Manager can be shown as inactive (grayed
out) or not shown at all. This depends on the following factors:
• Settings of the selection list mode (global list / user list)
• User Groups
- Users belonging to the group 'Administrator'
- Users not belonging to the group 'Administrator'
+ Users with write access to the *.ini file (selection list)
+ Users without write access to the *.ini file (selection list)
The administrator can use these factors to provide users with
individual functions.
The tables give an overview:
• for Windows see: Table 32 Ö134
• for Mac see: Table 33 Ö135
The tables show the features that are basically available. In addition,
individual features will not be displayed or will be displayed as
inactive. This depends on
– the embedded UTN server model
– the settings of the product-specific security mechanisms

Troubleshooting
This chapter describes some problems and their solutions.
Problem
• ’The UTN server signalizes the BIOS mode’ Ö136
• ’Some functions in the SEH UTN Manager are hidden, enabled or
appear dimmed’ Ö138
• ’A connection to the UTN server cannot be established’ Ö138
• ’A connection to the USB device cannot be established’ Ö138
• ’A connection to the myUTN Control Center cannot be
established’ Ö139
• ’The password is no longer available’ Ö139
The UTN server signalizes the BIOS mode
Possible Cause
The UTN server switches to the BIOS mode if the firmware functions
well but the software is faulty. This may happen in the case of an
incorrect software update, for example. The UTN server signalizes the
BIOS mode if
• the activity LED (yellow) blinks periodically and
• the status LED (green) is not active.
The UTN server is not operational in the BIOS mode.
If the UTN server is in the BIOS mode, the filter 'BIOS Mode' will be
created automatically in the device list of the InterCon-NetTool. The
UTN server will be displayed within this filter.

myUTN User Manual
Proceed as follows:
Start the InterCon-NetTool.
Select the UTN server from the device list.
(You will find the UTN server under the filter 'BIOS Mode'.)
Select Installation – IP Wizard from the menu bar.
The IP Wizard is started.
Follow the instructions of the wizard in order to assign an IP
address to the UTN server.
The IP address is saved.
Carry out a software update on the UTN server; see: Ö110.
The software will be saved in the UTN server. The UTN server
switches to the normal mode.
137
Appendix - Troubleshooting
Some functions in the SEH UTN Manager are hidden, enabled or
appear dimmed
Possible Cause
† Your user account does not have the required administrative
rights. This leads to restricted user rights in the SEH UTN
Manager; see: ’SEH UTN Manager - Function Overview’ Ö133.
† A function is not supported by the connected USB device (e.g.
the 'Print-On-Demand' feature is not supported by a hard disk).
Start the SEH UTN Manager as administrator. For more information,
refer to the documentation of your operating system.
A connection to the UTN server cannot be established
A common port will be used for the data transfer between the UTN
server and the SEH UTN Manager that is installed on the client.
Ö54.
Possible Cause
† The port numbers are not identical.
The current port number cannot be transferred to the SEH UTN
Managers that are installed on the clients.
The 'SNMPv1' parameter has been disabled; see: Ö41.
† The communication is blocked by a firewall.
A connection to the USB device cannot be established
Possible Cause
† The access control for USB devices is enabled Ö86.
† No driver software for the USB device is installed on the client.
† The USB device is already connected to another client.
myUTN User Manual
138
Appendix - Troubleshooting
A connection to the myUTN Control Center cannot be established
Eliminate possible error sources. First of all, check:
- the cabling connections
- the IP address of the UTN server Ö13 as well as
- the proxy settings of your browser
If you still cannot establish any connection, the following safety
mechanisms might be the cause:
† The access is protected via SSL/TLS (HTTPS) Ö82.
† The TCP port access control is enabled Ö84.
† The password protection is enabled Ö83.
† The cipher suites of the encryption level are not supported by
the browser Ö80.
The password is no longer available
Access to the myUTN Control Center can be protected by a
password. If the password is no longer available you can reset the
parameter values of the UTN server to their default settings to get
access to the myUTN Control Center Ö107. Previous settings will
be deleted.

Appendix - Additional Tool 'utnm'
8.6
Additional Tool 'utnm'
utnm
The additional tool 'utnm' has been developed for the myUTN
products of SEH Computertechnik GmbH. It is used for the
activation and deactivation of USB devices.
Use
In order to activate or deactivate a USB device with utnm,
commands are entered and run in a special syntax in the
command-line interface of the operating system.
As an alternative, a script will be written for the USB device. The
script contains commands in a special syntax. When it is run, the
commands will be executed automatically step by step by the
command-line interpreter.
Benefits and
Purpose
When using utnm, it is not necessary to open and/or install the
interface of the SEH UTN Manager (minimal version of the SEH UTN
Manager Ö20).
Frequently recurring command sequences (e.g. a device activation)
can be automated by means of scripts. The execution of scripts can
be done automatically (e.g. by means of login scripts).
