Carry out the hardware installation. The hardware installation comprises the connection of the UTN server to the network, the USB device and the power supply; see: 'Quick Installation Guide'.
General Information 1.6 Saving the IP Address in the UTN Server Why IP Addresses? An IP address is used to address network devices in an IP network. TCP/IP network protocols require the storing of the IP address in the UTN server so that the device can be addressed within the network. How Does the UTN Server Obtain IP Addresses? The UTN server is able to assign itself an IP address during the initial installation. Boot protocols are used to assign an IP address automatically to the UTN server.
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: 40. BOOTP The UTN server supports BOOTP, which means that the IP address of the UTN server can be assigned via a BOOTP server.
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.
General Information • To configure an IPv4 address via the myUTN Control Center, see: 34. • To configure an IPv6 address via the myUTN Control Center, see: 36. 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.
Administration Methods 2 Administration Methods You can administer and configure the UTN server in a number of ways. The following chapter gives you an overview of the various administration options. You will get information on when to use these methods and which functions these methods support.

Network Settings 3.2 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 commonIPv4. Both protocols are standards for the network layer of the OSI model and regulate the addressing and routing of data packets via a network.
Network Settings 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.
Network Settings Parameters Description 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.
Network Settings Tabelle 4: DNS Parameters Parameters Description DNS Enables/disables the name resolution via a DNS server. Primary DNS server Defines the IP address of the primary DNS server. Secondary DNS server Defines the IP address of the secondary DNS server. The secondary DNS server is used if the first one is not available. Domain name (suffix) Defines the domain name of an existing DNS server. 3.
Network Settings 3. Configure the SNMP parameters; siehe: Tabelle 5 40. 4. Click Save & Restart to confirm. The settings are saved. Tabelle 5: SNMP parameters Parameters Description SNMPv1 Enables/disables SNMPv1. Read-only Enables/disables the write protection for the community. Community SNMP community name The SNMP community is a basic form of access protection in which several participants with the same access rights are grouped together. SNMPv3 Enables/disables SNMPv3.
Network Settings 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.
Network Settings SMTP What Do You Want To Do? 'SMTP' (Simple Mail Transfer Protocol) is a protocol that controls the sending of emails in networks. SMTP is required in the UTN server to administer the UTN server via email and to run the notification service. ’Configuring POP3’ 42 ’Configuring SMTP’ 43 Configuring POP3 Requirements The UTN server is set up as user with its own email address on a POP3 server. 1. 2. 3. 4. Proceed as follows: Start the myUTN Control Center.
Network Settings Parameters Description POP3 - Ignore mail exceeding Defines the maximum email size (in Kbyte) to be accepted by the UTN server. (0 = unlimited) POP3 - User name Defines the user name used by the UTN server to log on to the POP3 server. POP3 - Password Defines the password used by the UTN server to log on to the POP3 server. Configuring SMTP Requirements The UTN server is set up as user with its own email address on a SMTP server. 1. 2. 3. 4.

SMTP - User name Defines the user name used by the UTN server to log on to the SMTP server. SMTP - Password Defines the password used by the UTN server to log on to the SMTP server.
Network Settings 3.7 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, 802.11g and IEEE 802.11n.
Network Settings 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.
Network Settings In order to configure the UTN server you must first establish a connection to a wired network by means of the network connector RJ-45; see: 'Quick Installation Guide'. Requirements The UTN server is connected to the network and the mains voltage. The UTN server is known to the wired network via its IP address, see: 14. 1. 2. 3. 4. 5. 6. Proceed as follows: Start the myUTN Control Center. Select NETWORK – WLAN. The available WLANs are shown in the network list.
Network Settings Tabelle 9: WLAN Parameters myUTN User Manual Mac Parameters Description Mode Communication mode) Defines the communication mode.

In order to identify a certain myUTN-800 if several are mounted in a rack, an identifier is shown in the display panel on the front side of the Dongleserver. By default, the identifier 'DS' is displayed. You can assign a freely definable identifier.
Device Settings 4.3 How to Configure the Device Time You can control the device time of the UTN server via a time server (SNTP server) in the network. A timeserver is a computer networking 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.
Device Settings UTN SSL Port Encrypted connection means that client and UTN server communicate via the UTN SSL port. The port number 9443 is preset. In order to use an encrypted connection you must enable the port encryption; see: 104. This UTN port or the UTN SSL port must not be blocked by a firewall. If required, you can change the port number on the UTN server.

Security 6 Security A number of security mechanisms are available to ensure optimum security for the UTN server. This chapter describes how to make use of these security mechanisms.
Security 6.1 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 (41) • Email: SMTP (41) • Web access to the myUTN Control Center: HTTPS (82) • Data transfer between the clients and the UTN server (and the connected USB devices): USB port (104) Encryption Level The encryption strength and thus the safety of the connection is defined via the encryption level.
Security The following encryption levels can be selected: • Compatible: Cipher suites with an encryption of 40 to 256 bit are used. • Low: Only cipher suites with a low encryption of 56 bit are used. (Fast connection) • Medium: Only cipher suites with an encryption of 128 bit are used. • High: Only cipher suites with a strong encryption of 128 to 256 bit are used.
Security 6.2 How to Control the Access to the myUTN Control Center You can protect the administrative access to the myUTN Control Center by user profiles. What Do You Want To Do? ’Specifying the Permitted Web Connection Type’ 82 ’Protecting the web access via password’ 83 The myUTN Control Center can also be protected by the SNMP security concept. For further information; see: • ’How to Configure SNMP’ 39.
Security Protecting the web access via password To protect the myUTN Control Center against unauthorized web access, you can use a passwort. If a password is set, only the start page of the myUTN Control Center can be visited and displayed. If you select a menu item, you will be asked to enter a password. You will also be asked to enter a non-definable user name. Leave this field blank at the password prompt. 1. 2. 3. 4. 5. Proceed as follows: Start the myUTN Control Center.
Security work elements with access rights 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. Test Mode The 'test mode' allows you to check the configured access protection. If the test mode is activated, access protection remains active until the UTN server is rebooted. After restarting, the protection is no longer effective. The 'test mode' option is activated by default.
Security 6.4 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.
Security What Do You Want To Do? ’Blocking access to USB devices’ 86 ’Unblocking access to USB devices’ 86 ’Specifying the Device Assignment on the USB Port’ 87 ’Disabling the USB Port Access Control’ 87 Blocking access to USB devices If you want to control the access to a USB device you must specify a key for the USB port via the myUTN Control Center. 1. 2. 3. 4. 5. Proceed as follows: Start the myUTN Control Center. Select SECURITY – USB port access.

The USB device box shows the vendor and product ID of the USB device. Click Save to confirm.
Security 6.5 How to Block USB Device Types USB devices are grouped into classes according to their function. For example, input devices such as keyboards belong to the group 'Human Interface Device' (HID). USB devices may present themselves as HID class USB devices but actually are used for abuse (known as 'BadUSB'). In order to protect the UTN server, you can block input devices which belong to the HID class. 1. 2. 3. 4. 5. myUTN User Manual Mac Proceed as follows: Start the myUTN Control Center.
Security 6.6 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.
Security • A requested certificate is created by a certification authority (CA) for the UTN server on the basis of a certificate request. • CA certificates are certificates that have been issued for a certification authority (CA). They are used for verifying certificates that have been issued by the respective certification authority. • S/MIME certificates (*.pem file) are used to sign and encrypt the emails that are sent by the UTN server.

Security 5. Click Create7Install. The certificate will be created and installed. This may take a few minutes. Tabelle 13: Parameters for the Creation of Certificates myUTN User Manual Mac Parameters Description Common name Is used to clearly identify the certificate. It is advisable to use the IP address or the host name of the UTN server to allow a clear assignment of the certificate to the UTN server. You can enter a maximum of 64 characters. Email address Specifies an email address.
Security Creating a Certificate Request for a Requested Certificate As preparation for using a certificate which is issued by a certification authority for the UTN server, a certificate request can be created in the UTN server. The request must be sent to the certification authority which creates an certificate on the basis of this request. The certificate must be in 'base64' format. If a certificate request has already been created, it will be overwritten. Proceed as follows: 1.
Security 5. Specify the requested certificate. 6. Click Install. The requested certificate will be installed in the UTN server. Installing the CA Certificate in the UTN Server In order to check the identity of the communicating parties of the UTN server, it is necessary to validate their certificates. For this, the root CA certificates of the certification authorities that have issued the certificates of said communicating parties are installed on the UTN server.
Security If a PKCS#12 certificate has already been installed on the UTN server, it will be overwritten. Requirements The certificate must be in 'base64' format. 1. 2. 3. 4. 5. 6. 7. Proceed as follows: Start the myUTN Control Center. Select SECURITY – Certificates. Click PKCS#12 certificate. Click Browse. Enter the PKCS#12 certificate. Enter the password. Click Install. The PKCS#12 certificate is saved in the UTN server.
Security Deleting Certificates Do not delete the certificate (CA/self-signed/PKCS#12) if only HTTPS is defined as the permitted connection type for the web access to the myUTN Control Center. If the corresponding certificate is deleted, the myUTN Control Center can no longer be reached. In this case you have to reset the parameters of the UTN server; see: 109. Requirements A certificate is installed on the UTN server. 1. 2. 3. 4.
Security 6.7 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.
Security 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. Mode of Operation 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.
Security 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.
Security tion. This ensures that the UTN server gets access to protected networks. Mode of Operation 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.
Security 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. Mode of Operation In the case of PEAP (compare EAP-TTLS, see 99), an encrypted TLS (Transport Layer Security) channel is established between the UTN server and the RADIUS server.
Security 7. Click Save & Restart to confirm. 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.
Security Requirements The UTN server is defined as user (with user name and password) on a RADIUS server. 1. 2. 3. 4. 5. 6. myUTN User Manual Mac Proceed as follows: Start the myUTN Control Center. Select SECURITY – Authentication. Select FAST from the Authentication method list. Enter the user name and the password that are used for the configuration of the UTN server on the RADIUS server.
