be set to the correct time and date.
This can be automated via a network time protocol server or you do this
manually.
Note:
Be sure to consider the notes regarding the impermissible special characters in
Chapter 1.2!
Select the automatic time setting via an NTP server, set the entry in the area
Date/time assignment to NTP server.
Before you activate the time server, ensure that the time you
NOTE:
specified via the manual settings differs by no more than +/- 5 min from
your time server.
In the field NTP server 1, enter the IP address or the host name of the time
server. Alternatively, you can set another time server in the field NTP server 1.
In the field Time zone, you enter the applicable value.
For manual time setting, please proceed as follows:
Set the entry in the field Date/time assignment to manually.
Enter the values that apply for you in the fields Time Zone, Date, and Time.
Page 18
Guntermann & Drunck GmbH UCON-IP-NEO Web interface
The time of the IP user module server must be identical with the time of the
local computer from which the web interface is accessed. You can execute this
by clicking on Execute in the line Set system time.
Click on Transfer to device to transmit your changes to the IP user module.
Page 19
Guntermann & Drunck GmbH UCON-IP-NEO Web interface
3.1.3 Syslog
In addition to the internal protocol, the IP user module can forward events to
syslog servers in the network in the syslog format.
You can enter up to two systems in the network as recipients of events – the
events are forwarded to any registered system via TCP or UDP to port 514
(default).
Here you can decide:
whether the IP user module shall send syslog messages
which log level shall send messages
whether messages should be sent locally and/or to a syslog server
Page 20
Guntermann & Drunck GmbH UCON-IP-NEO Web interface
3.1.3.1 Locally activate syslog
If you set the value to Activated in the filed Syslog local in the drop down
menu, the syslog messages are saved locally in the IP user module.
In the line Log level, you can determine the level from which messages are to
be saved locally.
The storage space, however, is limited. If the storage is full, old messages are
being overwritten by new messages. When the IP user module is restarted, all
messages that were stored locally will be deleted.
For this reason, it is recommended to also list a syslog server. This will be
explained in the next chapter.
3.1.3.2 Send syslog messages to a syslog server
As an alternative to sending syslog messages to the IP user module, you can
activate a syslog server as the recipient for the syslog messages. Overall, a
maximum of two syslog servers can be addressed via the IP user module.
In the area Syslog server 1 set the value to Activated in the drop down menu.
All additional fields in the area Syslog server 1 are activated and can be
edited.
Under Log level, you determine the level from which messages are to be sent
to the syslog server.
Page 21
Guntermann & Drunck GmbH UCON-IP-NEO Web interface
Under IP address and Port, you enter the IP address and the port of the
syslog server that is to receive the syslog messages.
In addition, you can also determine the protocol type (TCP or UPD).
If you want to transmit your entries to the IP user module by pressing the
button Transfer to device, but you have not entered an IP address for a
syslog server, the following message appears on your screen:
In this case, enter the required information for the certificate and the key.
If you have entered all required information, press the button Transfer to device. In the lower area, you receive a notification about the saving process
with a "Please wait..." message.
Note:
If you intend to also communicate with a second syslog server, please repeat the
previously described steps in the area Syslog server 1.
Be sure to consider the notes regarding the impermissible special characters in
Chapter 1.2!

Guntermann & Drunck GmbH UCON-IP-NEO Web interface
3.1.4 Import your own certificate
An SSL certificate is stored for the web server on the IP user module for the
safe connection via SSL. If the name of the device in the certificate does not
match with the name in the UPR, a warning message appears in the browser.
The only option to remove this message is for the user or the administrator of
the IP user module to import a certificate with the correct name. This can be
done via the web interface. Here, it should be ensured that
the certificate is a RSA certificate, and not a DSA certificate.
it is neither a Certificate Authority (CA) and nor a root certificate.
To create a certificate you can use the openssl program from the OpenSSL
package, which can be downloaded from http://www.openssl.org/.
As an example the commands are:
During the creation, some entries such as company, name, email address etc.
are requested that the creator may enter at will. The DNS name or the IP
address of the IP user module should be entered as Common name.
At the end of the process, 3 files were created: server.crt, server.csr and
server.key. The content of server.crt is entered in the WebIF into the
certificate field and the content of the server key is entered into the Key field.
Note:
The contents of the server.crt and server.key have to be entered in the
respective fields because the certificate can otherwise not be copied
successfully.
