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

• Windows XP and later
• Mac: OS X 10.8.x, OS X 10.9.x
• Ubuntu 12.04.x LTS (64-bit), Ubuntu 14.04.x LTS (64-bit) or Oracle
(64-bit) Linux 6.5 with Linux kernel 2.6.32 or higher, glibc 2.11.1
or higher and OpenSSL 1.0.1 or higher
This document describes the usage in Linux environments. Informa-
tion about the usage in other environments can be found in the rel-
evant system-specific User Manual. For further information; see:
’Documentation’ 7.
Procedure and Basic
Functions
After the SEH UTN Manager is started, the network will be scanned
for connected UTN servers. The network range to be scanned is
freely definable.
All UTN servers found will be shown in the 'network list' together
with the connected USB devices. The required UTN servers will be
selected and added to the 'selection list'. The UTN servers listed in
the selection list can then be used by the user. To use a USB device,
the user establishes a connection between the client and the USB
port of the UTN server to which the USB device is connected.
