Purpose
UTN servers comprise USB Deviceservers and USB Dongleservers. As USB Deviceservers they make non-networkready USB devices (e.g. USB hard disk drives, USB printers, etc.) and as USB Dongleservers non-network-ready USB
dongles accessible via TCP/IP network. For this purpose, the USB devices respectively USB dongles will be connected to the USB ports of the UTN server. Then the UTN (UTN = USB to Network) functionality and the corresponding software tool 'SEH UTN Manager' establish a virtual USB connection between USB device respectively
USB dongle and client. The USB device respectively USB dongle can be used as if it were connected locally.
Important:
The Dongleservers myUTN-80 and myUTN-800 are exclusively designed for the deployment of USB dongles.

3.1 How to Configure IPv4 Parameters
In the hardware installation ( ‘Hardware Installation Guide‘) the UTN server is connected to the network. The
UTN server then checks if it gets IP address dynamically via the boot protocols BOOTP (Bootstrap Protocol) or
DHCP (Dynamic Host Configuration Protocol). If this is not the case, the INU 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 20.
The IPv4 address assigned to the UTN server can be found via the software tools 'SEH UTN Manager' and 'InterCon-NetTool'. This step usually is carried out during the initial set up (
To optimally embed the UTN server into a TCP/IP network, you can configure different IPv4 parameters and/or
manually assign a static IP address to the UTN server.

Table 3: IPv4 parameters
Parameters Description
DHCP
BOOTP
ARP/PING
IP address IP address of the UTN server.
Subnet mask Subnet mask of the UTN server.
Gateway IP address of the network's standard gateway which the UTN server uses.
Enables or disables the protocols DHCP, BOOTP, and ARP/PING.
The IP address assignment via DHCP and BOOTP is automatic if one of these
protocols is implemented in your network.
You can use the commands ARP and PING to change an IP address which was
assigned via Zeroconf. The implementation depends on your system; read the
documentation of your operating system.
We recommend disabling these options once an IP
address has been assigned to 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.
With a gateway, you can address IP addresses from other networks.

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.
WARNING
UTN ( 1) and the corresponding SEH UTN Manager only work in IPv4 networks.
The InterCon-NetTool also only works in IPv4 networks.
In IPv6-only networks only the myUTN Control Center ( 6) can be accessed to
administrate 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 myUTN Control Center.
2. Select NETWORK – IPv6.
3. Configure the IPv6 parameters; Table 4 20.
4. Click Save & Restart to confirm.
The settings will be saved.
Table 4: 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.
20
myUTN User Manual Windows Network Settings
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 '/'.
3.3 How to Configure WLAN
The 'myUTN-55' is a WLAN device (Wireless Local Area Network) and supports the following standards:
• IEEE 802.11b
• IEEE 802.11g

identical settings) and the UTN server changes position, the UTN server will
automatically switch to the better signal without loss of connection if roaming
is activated.
(Infrastructure mode only)
Channel Enter your WLAN's channel (frequency range).
(Ad hoc mode only)
WARNING
Only use WLAN channels authorized for your country!
The UTN is an international product which supports a number of
channels. Channels are statutorily regulated by national authorities. So the UTN server might support channels which are forbidden to use in your country.
Inform yourself about national regulations.
Encryption method Select the encryption method that protects your WLAN.
Important:
We recommend to use hexadecimal keys for WEP.
Some access points/routers convert WEP keys in ASCII format to
hexadecimal format. In this case, the ASCII key on the UTN server
and the hexadecimal key on the access point/router do not match.
Use WEP key Defines the WEP key to be used.
Key 1–4 Defines the WEP keys. Four WEP keys are available. The key type defines the
max. number of characters as well as the permitted character set for the WEP
keys.
Important:
If your access point supports multiple WEP keys, make sure that
the key numbers on access point and UTN server are identical.
Example: The ABCDE must have the number 2 on both devices
(and not 1 on the access point and 2 on the UTN server).
PSK Defines the Pre Shared Key (PSK) for Wi-Fi Protected Access (WPA).
Authentication method Choose the authentication mechanism which is used in your WLAN.

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.
3.5 How to Configure SNMP
SNMP (Simple Network Management Protocol) is protocol for configuring and monitoring network elements. The
protocol controls communication between the monitored devices and the monitoring station (SNMP management tool). Information can be read and changed.
SNMP exists in 3 versions, the UTN supports version 1 and 2.
SNMPv1
SNMPv1 is the first and most simple SNMP version. A disadvantage is the insecure access control which is the community: a community groups monitoring station and monitored devices. This makes their administration easier.
There are two types of communities, read-only and read/write. For both the community name is also the password used between the monitoring station and the monitored devices. As it is transmitted as clear text, it does
not offer sufficient protection.
SNMPv3
SNMPv3 is the newest SNMP version. It contains enhancements and a new security concept which includes,
amongst other thins, encryption and authentication. Therefore, a SNMP user with name and password must be
created in the monitoring station. This user must then be specified in the UTN server.
Important:
The user accounts are also used to access the myUTN Control Center and thus are
to be defined under SECURITY - Device access ’How to Protect Access to the
myUTN Control Center (User Accounts)’ 53.
23

3.8 How to Use the UTN Server in VLAN Environments (only myUTN-80 and later)
The UTN server supports VLAN (Virtual Local Area Network) according to 802.1Q.
A VLAN divides a physical network into logical subnetworks. Each subnetwork is its own broadcast domain, so
data packets cannot be exchanged between subnetworks. VLANs are used to structure networks and, above all,
to secure them.
Each USB device can be assigned to a VLAN. To transfer VLAN data via the USB ports, you must first enter the
VLANs on the UTN server. After this, the USB ports used for forwarding data must be linked to the specified VLANs.
The access to USB devices can be regulated particularly well with VLAN: a defined
group of network users may use certain USB devices.
Inform yourself on how to implement VLAN in your environment and then set up the
UTN server for it.

5.1 How to Find UTN Servers/USB Devices in the Network
The software tool SEH UTN Manager is used to establish and manage connections to the USB devices connected
to the UTN servers.
After the SEH UTN Manager is started, the network has to be scanned for connected UTN servers. The network
range to be scanned is freely definable; the search can be effected via multicast and/or in definable IP ranges. The
default setting is multicast search in the local network segment.
All UTN servers found and their connected USB devices are displayed in the 'network list'. To use the USB devices
connected to the UTN server, you have to add the UTN server to the 'selection list'.
You can also directly add an UTN server to the selection list. To do this, you need to know its IP address.

myUTN User Manual Windows Working with the SEH UTN Manager
5.2 How to Establish a Connection to a USB Device
To connect a USB device to the client, a point-to-point-connection is established between the client and the USB
port of the UTN server to which the USB device is connected. The USB device can then be used as if it were directly
connected to the client.
Important:
Special case of compound USB devices
When connecting certain USB devices to a USB port of the UTN server, the selection
list displays several USB devices on this port. These are compound USB devices.
They consist of a hub and one or more USB devices that are all integrated into a single housing.
If the connection is established to a port with a connected compound USB device,
all USB devices shown will be connected to the user's client. In this case, each integrated USB device occupies a virtual USB port of the UTN server. The number of
these virtual USB ports is limited depending on the UTN server model. If the limit is
reached, no further USB devices can be used on this UTN server.

All provisions (driver installation, etc.) necessary to operate the USB device locally (i.e. connected directly to
the client) have been met on the client. Ideally, the USB device has been connected and operated on the client
locally according to the instructions of the manufacturer.
The USB port is

myUTN User Manual Windows Working with the SEH UTN Manager
5.3 How to Cut the Connection between the USB Device and the Client
If a USB device is connected to a client, the connection is of a point-to-point type. As long as the connection is
established, other users cannot connect the USB device to their client and thus cannot use it. For this reason, you
have to cut the connection once you do not use the USB device any longer.
To cut the connection between USB device and client, you deactivate the connection between the client and the
USB port of the UTN server to which the USB device is connected.
• Usually the connection is cut by the user via the SEH UTN Manager 38.
• In addition, the administrator can deactivate the connection via the myUTN Control Center 38.
• You can also set up an automatic deactivation (Auto Disconnect) 39.
Cutting the Device Connection via the SEH UTN Manager

5.4 How to Request an Occupied USB Device
If a USB device is connected to a client, the connection is of a point-to-point type. As long as the connection is
established, other users cannot connect the USB device to their client and thus cannot use it.
If you want to use an occupied USB device, you can request it. The other user will receive a release request in form
of a pop up. If the user follows your request and releases the USB device by deactivating the connection to the
USB device, the connection between the USB device and your client will automatically be activated.
The SEH UTN Manager (complete version) is installed on the client 8.
The SEH UTN Manager (complete version) is installed on the client of the user who uses the USB device 8.

5.5 How to Automate USB Device Connections and Program Starts
Connections to USB ports of the UTN server and the connected USB devices can be automated. Simple to complex
processes can be implemented.
• Automatic Connection If a USB Device Is Connected (Auto-Connect) 39
• Automatic Deactivation of the Connection after a Time Defined (Auto-Disconnect) 39
• Automatic Connection between a USB Device and Client When a Print Job Is Received (Print-On-Demand)
40
• Creating a UTN Action: Automated Connections and Program Starts without the SEH UTN Manager Interface
40
This chapter describes features of the SEH UTN Manager with which automatisms are
set up. Users who have expert knowledge in scripting should use the command line
tool 'utnm' 45.
Automatic Connection If a USB Device Is Connected (Auto-Connect)
Auto-Connect automatically establishes a connection to a USB port and the connected USB device as soon as a
USB device is connected to the USB port. Auto-Connect must be activated for each USB port and works for all USB
devices which are connected to the USB port.
The SEH UTN Manager (complete version) is installed on the client 8.
The USB port is shown in the selection list 35.
You are logged on to the client as administrator.
1. Start the SEH UTN Manager.
2. Select the UTN server from the selection list.
3. In the menu bar, select UTN server – Activate Auto-Connect.
The dialog Activate Auto-Connect appears.
4. Tick the option for the desired USB ports.
5. Click OK.
The setting will be saved. The connection to the USB port and the connected USB device is automatically and
immediately activated. If you disconnect the USB device and reconnect it, the connection is again automatically established.
Important:
If you manually deactivate an established USB port connection that was activated
by Auto-Connect, the Auto-Connect setting will be deactivated as well. If you want
to use Auto-Connect again, you will have to configure it anew later on.
Automatic Deactivation of the Connection after a Time Defined (Auto-Disconnect)
Auto-Disconnect deactivates the connection to a USB port and the connected USB device after a previously defined time. 2 minutes before time runs out, the user will receive a notification and is asked to deactivate their connection in order to prevent data loss and error states. Optionally, a one-off prolongation of the connection by the
duration of the defined time can be activated. In this case, the user can choose to prolong the connection or decline it when the notification pops up.
Auto-Disconnect allows a large number of network participants to access a small number of devices and avoids
idle times.
You can be notified if a connection is automatically disconnected and the port thus is
free. For this purpose, set up a notification if the USB port is available 42.

Creating a UTN Action: Automated Connections and Program Starts without the SEH UTN Manager Interface
UTN Actions are small files which contain a script that automates the connections to USB ports including connected USB devices. The process defined in the script runs automatically when the file is executed. Since the 'SEH UTN
Service' is active in the background, the user does not have to start the SEH UTN Manager interface. I.e., UTN Actions can be used with the complete ( 8) and minimal version ( 8).
UTN Actions are for realizing simple scenarios, such as activating a connection, as well as complex procedures,
such as activating a connection and starting an application with time delay. You can create the UTN action with a
wizard. The wizard is only available in the complete version ( 8) of the SEH UTN Manager. You can create the
following UTN Actions:
• 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 USB port and
the connected USB 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 a UTN Action which starts an application and ac-
40
myUTN User Manual Windows Working with the SEH UTN Manager
tivates the USB port and the connected USB device. Additionally, you can define a port 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 for the activation and deactivation of the USB port and the connected USB device. You can define additional options.
- A script for starting the application and activating the USB port and the connected USB device. Additionally, you can define a delay
for the start of the application, the deactivation of the USB port after the closing of the application and additional options. Finally,
the complete UTN Action will be created automatically by the SEH UTN Manager and saved by the user.
UTN Actions are based on the command line tool 'utnm'. We recommend experts to
use this tool, if they want to create very complex scripts without restraints 45.
The SEH UTN Manager (complete version) is installed on the client 8.
The USB port is shown in the selection list 35.
1. Start the SEH UTN Manager.
2. Select a port from the selection list.
3. In the menu bar, select Port – Create UTN Action.
The dialog Create UTN Action appears.
4. Follow the instructions of the wizard.
A UTN Action will be created. The UTN Action is run by double-clicking the file.
Figure 7: Create UTN Action dialog
Shortcuts can be moved to any place and renamed after they have been saved.
(Experts only) Custom UTN Actions which activate or deactivate USB devices can be
edited after their creation. To do this, edit the command line in the shortcut target.
Expert mode (script): You can also edit the script after its creation using a simple text
editor.

5.7 How to Use the Selection List and Manage User Access Rights with It
The selection list is the main element in the SEH UTN Manager and shows all embedded UTN servers. USB devices
can only be used if the UTN server to which they are connected is on the list ( 35). By controlling the selection
list you consequently control the user's access to UTN servers and the connected USB devices.
By default, all client users use the global selection list in the SEH UTN Manager. However, you can set a user selection list for the client users. This list can be compiled by the users themselves. Alternatively, you as client administrator restrict user rights and provide a list with which only the UTN servers you define can be used.

5.8 How to Use the SEH UTN Manager without Graphical User Interface
(utnm)
The SEH UTN Manager is available in two versions 8. It can be used without graphical user interface in the min-
imal version. To do so, the tool 'utnm' is utilized to use UTN features via the command line of the operating system:
• directly, by entering commands in a certain syntax and executing them
• via scripts which contain commands in a certain syntax that will be executed automatically and step by step
by the command line interpreter
Use scripts to automate frequently recurring command sequences such as port activations.
The execution of scripts can be automated as well, e.g. by means of login scripts.
• Syntax 45
• Commands 45
• Return 47
• Using utmn via Command Line 48
• Creating a utnm Script 48

6.1 How to Encrypt the USB Connection
To secure the USB connections, you encrypt the data transfer between the clients and the USB devices connected
to the UTN server. The encryption has to be activated individually for each connection, i.e. for each USB port.
Important:
Only payload will be encrypted. Control and log data will be transmitted without
encryption.
For encryption the protocols SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are used.
The encryption strength is defined via the encryption protocol and level 51.
WARNING
The SEH UTN Manager does not support the encryption level Low. If you set up
Low in combination with an encrypted USB connection, a connection cannot be
established.
Use an encryption level as high as possible.
If connections are encrypted, client and UTN server communicate via the UTN SSL port. By default, that is port 9443.
If the port is already used in your network, e.g. for another application, you can change the port number 31.

unencrypted connection
The encryption strength is defined via the encryption protocol and level 51. When an encrypted connection is to be established, the client asks for a certificate via a browser ( 56). This certificate must be accepted
by the browser; read the documentation of your browser software.
WARNING
Current browsers do not support low security settings. With them a connection
cannot be established.
Do
not use the following combination: Encryption protocol HTTPS and encryption
level Low.
6.3 How to Define the Encryption Strength for SSL/TLS Connections
Some connections to and from the UTN server can be encrypted with the protocol SSL (Secure Sockets Layer) and
its successor TLS (Transport Layer Security):
• Email: POP3 ( 25)
• Email: SMTP ( 25)
• Web access to the myUTN Control Center: HTTPS ( 51)
• Data transfer between the clients and the UTN server (and the connected USB devices): USB connection (
51)
The encryption strength and thus the safety of the connection is defined via the encryption protocol and level.
You can choose both.
Each encryption level is a collection of what is called cipher suites. A cipher suite in turn is a standardized sequence of four cryptographic algorithms that are used to establish a secure connection. Based on their encryption
strength they are grouped to encryption levels. Which cipher suites are supported by the UTN server, i.e. are part
of an encryption level, depends on the chosen encryption protocol. You can choose between two encryption levels:
• Any: The encryption is automatically negotiated by both communicating parties. The strongest encryption
supported by both parties will always be chosen.
• Low: Only cipher suites with a low encryption are used. (Fast data transfer)
• Medium
• High: Only cipher suites with an strong encryption are used. (Slow data transfer)
When a secure connection is established, the protocol to be used and a list of supported cipher suites are sent to
the communication partner. A cipher suite is agreed upon that will be used later on. The strongest cipher suite
51
myUTN User Manual Windows Security
that is supported by both parties will be used by default.
WARNING
If the communication partner of the UTN server does not support the protocol selected and/or if there is no cipher suite that is supported by both parties, the SSL/
TLS connection will not be established.
If problems occur, select different settings or reset the parameters of the UTN server
66.
If you want the UTN server and its communication partner to automatically negotiate
the settings, set both options to Any. With these settings, the chances that a secure
connection can be established are the highest.
1.Start the myUTN Control Center.
2. Select SECURITY – SSL connections.
3. In the Encryption protocol area, select the desired protocol.
WARNING
Current browsers do not support SSL. If you use an up-to-date browser and set the
combination SSL and HTTPS only for accessing the myUTN Control Center (
51), a connection cannot be established.
Use TLS (and
not SSL).
Important:
Which protocols are supported by the UTN server depends on the product hardware and the installed firmware/software.
4. In the Encryption level area, select the desired level.
WARNING
Current browsers do not support cipher suites from the Low level. If you use an
up-to-date browser and set the combination Low and HTTPS only for accessing
the myUTN Control Center ( 51), a connection cannot be established.
Use an encryption level as high as possible.
WARNING
The SEH UTN Manager does not support the encryption level Low. If you set up
Low in combination with an encrypted USB connection ( 49), a connection
cannot be established.
Use an encryption level as high as possible.

6.4 How to Protect Access to the myUTN Control Center (User Accounts)
By default, everyone who can find the UTN in the network can access its myUTN Control Center. To protect the
UTN from unwanted configuration changes, you can set up two user accounts:
• Administrator: Complete access to the myUTN Control Center. The user can see all pages and change settings.
• Read-only user: Very restricted access to the myUTN Control Center. The user can only see the 'START' page.
If you have set up user accounts, a login screen is displayed when the myUTN Control Center is started. You can
choose between two login screens:
• List of users: User names are displayed. Only the password has to be entered.
• Name and password dialog: Neutral login screen in which user name and password have to be entered. (better protection)
A user account allows for multiple logins, i.e. the account can be used by a single user or by a group of users. Up
to 16 users can be logged in at the same time.
Important:
The user accounts for myUTN Control Center access are also used for SNMP 23.
Consider this when setting up user accounts.
For stronger security, you can use a session timeout. If there is no activity within a defined timeout, the user will
automatically be logged out.
1. Start the myUTN Control Center.
2. Select SECURITY – Device access.
3. Define the two user accounts. To do this, in the area User accounts enter a User name and Password respectively.
You can show the typing if you want to make sure that there are no typing errors in
the password.
4. Tick Restrict Control Center access.
5. Choose the login screen type: list of users or name and password.
6. Tick Session timeout and into the Session duration box enter the time in Minutes after which the timeout
is to be effective.
7. To confirm, click Save.
The settings will be saved.

6.5 How to Block Ports of the UTN Server (TCP Port Access Control)
You can restrict access to the UTN server by blocking ports with the ‘TCP port access control’. If a port is blocked,
the protocols respectively services using this port cannot establish a connection with the UTN server. Thus attackers have less room for attack.
The security level defines which port types are blocked:
• UTN access (blocks UTN ports)
• TCP access (blocks TCP ports: HTTP/HTTPS/UTN)
• All ports (blocks IP ports)
You have to define exceptions so that your desired network elements, e.g. clients or DNS servers, can establish a
connection with the UTN server.
WARNING
The ‘ test mode’ is active by default so that you can test your settings without locking yourself out. Your settings will be active until the UTN is restarted, afterwards
access is no longer restricted.
After you have successfully tested your settings, you have to deactivate the test
mode so that access control is permanent.
1. Start the myUTN Control Center.
2. Select SECURITY – TCP port access.
3. Tick Port access control.
4. In the Security level area, select the desired protection
5. In the Exceptions area, define the network elements that are to have access to the UTN server. To do this, enter the IP or MAC (hardware) addresses and tick the options.
Important:
• MAC addresses are not delivered through routers!
• The use of wildcards (*) allows you to define subnetworks.
6. Make sure that the Test mode is enabled.
7. Click Save & Restart to confirm.
The settings will be saved.
The port access control is activated until the device is restarted.
8. Check the port access and if the myUTN Control Center can be reached.
Important:
If the myUTN Control Center cannot be reached, restart the UTN server 64.
9. Deactivate the Test mode.
10. Click Save & Restart to confirm.

6.6 How to Control Access to USB Devices (only myUTN-80 and later)
You can restrict the access to the USB ports and the connected USB devices:
• USB port key control A key is defined for the USB port. Neither the USB port nor the connected USB device are
shown in the SEH UTN Manager, i.e. the USB device cannot be used. Only if the key for the USB port is entered
in the SEH UTN Manager, the USB port and the connected USB device appear.
• USB port device assignment: A certain USB device is assigned to a USB port. This is achieved by linking the USB
port and USB device through the vendor ID (short VID) and product ID (short PID) of the USB device. The combination of VID and PID is specific to a certain USB device model which means that only USB devices of this
specific model can be used on the USB port. This way you can assure, that (security) settings cannot be circumvented by connecting USB devices to other ports.

2. Select SECURITY – Device access.
3. Tick/clear Disable input devices (HID class) in the USB devices area.
4. To confirm, click Save.
The setting will be saved.
6.8 How to Use Certificates
The UTN server has its own certificate management. Digital certificates are data sets, which confirm the identity
of a person, object, or organization. In TCP/IP networks they are used to encrypt data and to authenticate communication partners.
The UTN needs a certificate for:
• participating in the authentication mechanisms EAP-TLS, EAP-TTLS and PEAP 60
• protecting email communication (POP3/SMTP via SSL/TLS) 25
• protecting the connection between the clients and the connected USB devices 49
• protecting the connection to the myUTN Control Center (with HTTPS) 51
The following certificates can be used in the UTN server:
• 1 self-signed certificate
Certificate generated by the UTN server and signed by the UTN server itself. The certificate confirms the UTN
server's identity.
• 1 client certificate, i.e. 1 requested certificate
The client certificate confirms the identity of the UTN server with the help of an additional trustworthy authority which is the certification authority (short CA).
- Requested certificate: As first step, a certificate request is generated on the UTN server and then the request
is sent to a certification authority. In the second step, the certification authority creates a certificate based
on the request for the UTN server and signs it.
- PKCS#12 certificate Exchange format for certificates. You have a certification authority generate a certificate
which is stored in password-protected PKCS#12 format for the UTN server. Then you transport the PKCS#12
file to the UTN server and install it (and thus the certificate in it).
• 1 S/MIME certificate
The UTN server uses the S/MIME Certificate to sign and encrypt emails which is sends. The corresponding private key (PKCS#12 format) has to be installed as certificate of it's own in the email program (Microsoft Outlook
etc.) so that emails can be verified and, if necessary, decrypted.
(only myUTN-80 and later)
• 1–32 CA certificates, also known as root CA certificates.
or 1 PKCS#12 certificate
56
myUTN User Manual Windows Security
Certificates which are issued for a certification authority and confirm its identity. They are used for verifying
certificates that have been issued by the respective certification authority. In case of the UTN server these are
the certificates of communication partners to verify their identity (chain of trust). Thus multi-level public key
infrastructures (PKIs) are supported.
Important:
Upon delivery, a default certificate is stored in the UTN server. This certificate is
issued by SEH Computertechnik GmbH for each device specifically.

6.9 How to Configure Network Authentication (IEEE 802.1X)
Authentication is the proof and verification of an identity. With it your network is protected from abuse, because
only authorized devices have access.
The UTN supports authentication according to the IEEE 802.1X standard which is based on EAP (Extensible Authentication Protocol).
If you use authentication according to IEEE 802.1X in your network, the UTN server can participate:
• Configuring EAP-MD5 60
• Configuring EAP-TLS 60
• Configuring EAP-TTLS 61
• Configuring PEAP 61
• Configuring EAP-FAST 62
Configuring EAP-MD5
EAP-MD5 (Message Digest #5) is a user-based authentication via a RADIUS server. First, you have to create a user
(user name and password) on the RADIUS server for the UTN server. Afterwards you set up EAP-MD5 on the UTN
server.
A user account for the UTN server is set up on the RADIUS server.
1. Start the myUTN Control Center.
2. Select SECURITY – Authentication.
3. From the Authentication method list, select MD5.
4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS
server.
5. Click Save & Restart to confirm.
The settings will be saved.
Configuring EAP-TLS
EAP-TLS (Transport Layer Security) is a mutual, certificate based authentication via a RADIUS server. In this method, UTN server and RADIUS server exchange certificates through an encrypted TLS connection.
Both RADIUS and UTN server require a valid, digital certificate signed by a CA. This requires a PKI (Public Key Infrastructure).
60
myUTN User Manual Windows Security
WARNING
Follow the instructions below in the given order. If you do not follow the order, the
UTN server might not be reachable in the network.
In this case, reset the parameters of the UTN serve 66.
1. Create a certificate request on the UTN server 58.
2. Create a certificate using the certificate request and the authentication server.
3. Install the requested certificate on the UTN server 58.
4. Install the root CA certificate of the certification authority that has issued the certificate of the authentication
server (RADIUS) is installed in the UTN server 59.
5. Start the myUTN Control Center.

7. Select TLS from the Authentication method list.
8. From the list EAP root certificate, select the root CA certificate.
9. Click Save & Restart to confirm.
The settings will be saved.
Configuring EAP-TTLS
In EAP-TTLS (Tunneled Transport Layer Security), a TLS-protected tunnel is used for exchanging secrets. The method consists of two phases:
1. Outer authentication: An encrypted TLS (Transport Layer Security) tunnel is created between UTN server and
RADIUS server. To do this, the RADIUS server authenticates itself to the UTN server using a certificate that was
signed by a CA.
2. Inner authentication: In the tunnel the authentication (via CHAP, PAP, MS-CHAP, or MS-CHAPv2) takes place.
A user account for the UTN server is set up on the RADIUS server.
For increased security during connection establishment (optional): The root CA certificate of the certification au-
thority that has issued the certificate of the authentication server (RADIUS) is installed in the UTN server 59.
1. Start the myUTN Control Center.
2. Select SECURITY – Authentication.
3. Select TTLS from the Authentication method list.
4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS
server.
5. Select the settings which secure the communication in the TLS channel.
6. Increase the security during connection establishment (optional):
From the list EAP root certificate, select the root CA certificate.
7. Click Save & Restart to confirm.
The settings will be saved.
Configuring PEAP
With PEAP (Protected Extensible Authentication Protocol), an encrypted TLS (Transport Layer Security) tunnel is
established between the UTN server and the RADIUS server. To do this, the RADIUS server authenticates itself to
the UTN server 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 method is very similar to EAP-TTLS ( 61), but other methods are used to authenticate the UTN server.
A user account for the UTN server is set up on the RADIUS server.
For increased security during connection establishment (optional): The root CA certificate of the certification au-
thority that has issued the certificate of the authentication server (RADIUS) is installed in the UTN server 59.

7. Click Save & Restart to confirm.
The settings will be saved.
Configuring EAP-FAST
EAP-FAST (Flexible Authentication via Secure Tunneling) is a specific EAP method developed by the company Cisco.
As with EAP-TTLS ( 61) and PEAP ( 61) a secure tunnel protects data transmission. However, the server does
not authenticate itself with a certificate. Instead it uses PACs (Protected Access Credentials).
A user account for the UTN server is set up on the RADIUS server.
1. Start the UTN Control Center.
2. Select SECURITY – Authentication.
3. Select FAST from the Authentication method list.
4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS

7.3 How to Backup Your Configuration
All settings of the UTN server (exception: passwords) are saved in the file '<Default-Name>_parameters.txt'.
You can save this parameters file as backup copy to your local client. This way you can return to a stable configu-
ration status at any time.
You can edit the parameter values in the backed up file using a text editor . Afterwards, the edited file can be load-
ed onto one or more UTN servers. The device(s) will then adopt the parameter values of the file.
You can find a detailed description of the parameters in the ’Parameter Lists’ 73.
The Dongleserver myUTN-800 also has an automatic backup feature. It saves the parameter values, passwords
and certificates installed on the UTN server automatically to a connected SD card. After a parameter or certificate
change, the backup will be updated automatically. To transfer the settings to another UTN server, you simply insert the SD card into the other device. After a cold boot (interruption and re-establishment of the power supply),
the settings will be loaded automatically.
WARNING
If the SD card is lost or stolen, your environment becomes vulnerable (certificates,
passwords).
Therefore, you have to take all necessary precautions to protect the UTNserver if
you use the automatic backup.

Compound USB device
A compound USB device consists of a hub and one or more USB devices that are all integrated into a single housing. Dongles are often compound USB devices.
If a compound USB device is connected to a USB port of the UTN server, all integrated USB devices will be shown
in the myUTN Control Center and in the selection list of the SEH UTN Manager. When the port connection is activated, all displayed USB devices will be connected to the user's client. It is not possible to activate a port connection to only one of the USB devices.
Default name
Device name which is assigned by the manufacturer and cannot be changed. If you are using several identical
UTN servers, you can identify a certain device with it.
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 the hardware address.
You can see the default name in the myUTN Control Center or InterCon-NetTool.
Hardware address
The hardware address (often also referred to as Ethernet address, physical address or MAC address) is the worldwide unique identifier of a network interface. If you are using several identical UTN servers, you can identify a
certain device with it.
The manufacturer has defines the address in the hardware of the device. It consists of 12 hexadecimal numbers. The first six numbers represent the manufacturer, while the last six numbers identify the individual
device. The characters for separating the numbers depend on the platform. In Windows '-' are used.
Hardware address

• SEH UTN Manager: Features Are Not Available or Deactivated 72
Fix
UTN Server: BIOS Mode
The UTN server switches to the BIOS mode if the firmware works but the software is faulty. This may happen in the
case of an incorrect software update, for example.
The LEDs indicate the BIOS mode:
• Status LED is off
• Activity LED blinks periodically
In addition, the UTN server can be found in the BIOS Mode filter in the InterCon-Net-
Tool.
WARNING
The UTN server is not operational if it is in BIOS mode.
Follow the instructions below to remove the error.
To switch the UTN server from BIOS to normal mode, you have to first assign a temporary IP address to the device
and then load software onto it. After the software update the UTN server switches to normal mode and will be
assigned a new, permanent IP address.
1. Start the InterCon-NetTool
2. In the device list, select the UTN server.
(You find the UTN-Server under the filter BIOS Mode.)
3. In the menu, select Installation–IP Wizard.
Der IP Wizard is started.
4. Follow the instructions of the wizard in order to assign an IP address to the UTN server.
The IP address is saved.
5. Update the UTN server's software 64.
The software is saved in the UTN server.
The UTN server switches to normal mode.
UTN Server: Connection Cannot Be Established
You find the UTN server in the network and can reach it via TCP/IP connection. However, a connection via the SEH
UTN Manager cannot be established.
Possible causes:
70
myUTN User Manual Windows Appendix
• A firewall or some other security software blocks communication.
Add the UTN port respectively UTN SSL port as exception to your firewall or security software. Refer to the documentation of your firewall or security software on how to do this.
• The port numbers in the SEH UTN Manager and on the UTN server are not identical: You changed the port
number while SNMPv1 is deactivated, so that the change cannot be communicated to the SEH UTN Manager
31.
myUTN Control Center: Connection Cannot Be Established
Eliminate possible error sources. Check:
• the cabling connections,
• the IP address of the UTN server 18
• the proxy settings of your browser (refer to the documentation of your browser for more information)
If you still cannot establish any connection, the following safety mechanisms might be the cause:
• Access is protected via SSL/TLS (HTTPS) 51.
• Access is protected via SSL/TLS (HTTPS) and you deleted the certificate (self-signed/CA/PKCS#12) 56.
Reset the UTN server to its default parameter values 66.In the process, new certificates will be created.
WARNING
If you reset the device, all settings are lost and the IP address might change.
If required, determine the new IP address 18.
• TCP port access control is enabled 54.
• The cipher suites of the encryption level are not supported by the browser 51.
myUTN Control Center: You Lost User Name and/or Password
If the access to the myUTN Control Center is protected but you have lost the access credentials, you can reset the
UTN server to its default values. After the reset you can access the myUTN Control Center again, as it is not protected by default.
WARNING
If you reset the device, all settings are lost and the IP address might change.
If required, determine the new IP address 18.
SEH UTN Manager: A Connection to the USB device Cannot Be Established
Possible causes:
• The USB port is already connected to another client.
Wait until the other user terminates the connection or request the device 38.
• The driver software for the USB device is not installed on the client.
Install the driver software for your USB device. Refer to the documentation of your USB device on how to do
this.
SEH UTN Manager: USB Devices Are Not Shown
Eliminate possible error sources: Check if the USB device is connected to the UTN server.
If the USB device is still not displayed, the following issues might be the cause:
• Several compound USB devices ( 69) are connected to the UTN server. Each integrated USB device occupies a virtual USB port of the UTN server. The number of these virtual USB ports is limited. If the limit is reached,
no further USB devices can be used on this UTN server ( 37).
71
myUTN User Manual Windows Appendix
• The USB port is deactivated 30.
• The USB port key control is activated for the USB device 55.
Only once the key for the USB port is entered in the SEH UTN Manager, the USB port and the connected USB
device appear.
SEH UTN Manager: A USB Device Is Connected to the USB Port, but several USB Devices Are Displayed
Possible causes:
• A USB hub is connected to the USB port of the UTN server.
• The connected USB device is a compound USB device ( 69). It consists of a hub and one or more USB devices that are all integrated into a single housing. When the connection to the USB port is established, all displayed USB devices will be connected to the user’s client and can be used.
SEH UTN Manager: Features Are Not Available or Deactivated
Possible causes:
• Your client user account does not have the required administrative rights. This restricts user rights in the SEH
UTN Manager as well. More details can be found in chapter ’SEH UTN Manager – Feature Overview’ 97.
Start the SEH UTN Manager as administrator. Refer to the documentation of your operating system on how to
do this.
• A function is not supported by the connected USB device (e.g. the 'Print-On-Demand' feature is not supported
by a hard disk).

adhoc Defines the communication mode (network
infrastructure):
• Ad hoc: Your WLAN is a decentralized adhoc-network in which devices communicate
directly with each other (peer-to-peer).
• Infrastructure: Your WLAN is an infrastructure network with an access point/router as
centrals communication hub. The access
point is connected to the fixed network with
a cable.
SEH Enter your WLAN’s network name, also known
as SSID (Service Set Identifier).
3 Enter your WLAN's channel (frequency range).

WARNING
Only use WLAN channels authorized for your country!
The UTN is an international product
which supports a number of channels. Channels are statutorily regulated by national authorities. So the
UTN server might support channels
which are forbidden to use in your
country.
