Internet and Net Access

"WIreless Netzwerk zur Unterstützung der Lehre an der Universität Mainz"<
The Data Center operates an un-encrypted Wireless Local Area Network. Please note: un-encrypted means that your data transactions can be read by anyone). To use it, all you need to do is to authenticate via a webpage: login.uni-mainz.de. Please also see our documentation about → network access.

Please note: if you are using Windows XP, Windows Vista or Windows 7 we recommend using the firewall that comes with the operating system. For these systems we would advise against installing an additional firewall software.

If your operating system and your hardware support security enabled (encrypted) wireless LANs (almost all newer devices support encryption), then we recommend using one of these other SSIDs: → uni-mainz or → eduroam.

Establishing the connection

Look for the network eduroam under Einstellungen → Netzwerke. Then click Verbinden.

Enter your user name (JGU account) in the form username@uni-mainz.de and your password. Then click OK.

In front of the @ symbol please enter your real user name, not, for example, your mail alias, which is different!

The following notification will then appear:

For displaying the details of the certificate click on Zertifikatsdetails anzeigen.
Something like the following will then appear:

From 9 July 2019, 18.00, you will find the following finger print in the details of the certificate:

Then click on: Verbinden.

In case this doesn't work ...

... and you receive the note 'Verbindung zum Netzwerk kann nicht hergestellt werden': this probably means that the necessary certicate is not installed on your device. To solve this problem, you may use another network (winulum, for example) and then open a https URL like OWA (→ https://mail.uni-mainz.de) or JoguStINe (→ https://jogustine.uni-mainz.de) with Internet-Explorer (not Chrome, Opera, Firefox or another browser, because it won't work there).
If you open that URL in Internet Explorer, the necessary certificate should be automatically installed and will then be availabe for wireless connections like eduroam and uni-mainz.

The University of Mainz takes part in the → eduroam network, in which universities have joined forces in Europe (in the meantime even worldwide).

Under the network name (SSID) eduroam, the center operates campus-wide data processing for an encrypted wireless LAN. WPA/WPA2 Enterprise with TKIP and AES encryption serve as security mechanisms. The coverage is consistent with the coverage for the wireless LAN uni-mainz (with the exception of the University Clinic areas).Members of other universities participating in the European eduroam network can connect to the eduroam wireless LAN via the University of Mainz, by logging in with the JGU account of their home university.
Conversely, members of the University of Mainz who are at other universities in the eduroam network may use eduroam with the Mainz JGU account.

Instructions for setting up eduroam with various operating systems can be found below and in the navigation bar.

When using the following instructions for configuring eduroam on various operating systems plese note:

Usually it should not be necessary to download a certificate any more. The certificate we use is already available on most devices.

Users who have already used eduroam with an older configuration (using the orca certificate that had to be separately installed) will have to delete their existing eduroam connection first and may then re-configure it.

• eduroam for Windows 10 (documentation in German)
• eduroam for Windows 8
• eduroam for Windows 7
• eduroam for MacOS X (documentation in German)
• eduroam for iPod, iPhone
• eduroam for Ubuntu Linux
• eduroam for Android (documentation in German)

The Data Center operates two campus-wide wireless LANs in accordance with the 802.11a/b/g/n standard: one with the network name (SSID) Uni-Mainz and one with the network name eduroam. Both are encrypted and provide increased security.

Connecting to the wireless network Uni-Mainz is usually not complicated. The following description shows how to configure it with Windows 7.

For other operating systems please use → the instructions for eduroam. The only difference is the use of Uni-Mainz as the name of the network (SSID), as seen here.

Please click on the network symbol in the task bar at the bottom right.This will show all available wireless networks. Please click on Uni-Mainz, then Verbinden.

You will now be asked for the user name and password of your JGU account.

Once you have entered those data and clicked OK, then, if this is the first configuration of this connection, you will see a security notification. Please click on: Details.

The right certificate is issued for the server radius.zdv.uni-mainz.de and it contains the following information for verification purposes. Depending on your device and operating system, you will only be shown part of this information:

CN = radius.zdv.uni-mainz.de
O = Johannes Gutenberg-Universitaet Mainz
L = Mainz
S = Rheinland-Pfalz
C = DE

Finger print: ‎

Finger print form 9 July 2019, 18.00:
‎‎e7 78 56 db b8 2c 23 cf f1 26 94 48 42 f4 cd 54 b3 5b 6b 7d

If the data shown conforms with the data shown here, you may accept the certificate.

If you then click Verbinden the connection will be established (and the server radius.zdv.uni-mainz.de will be set as 'trustworthy').

The ZDV offers various free options for accessing the Internet and the university's internal network. This applies to computers and end devices on campus as well as via network connections from off campus. For this purpose, we operate an area-wide wireless LAN on campus as well as a high-bandwidth wired network.

The connection to the Internet is made via the Rhineland-Palatinate scientific network WiN-RP, which is also operated by the ZDV and connects all universities and universities of applied sciences in the state via a 40 GBit/s ring to the global exchange point DE-CIX in Frankfurt.

Here you will find your options of net access on campus - and also from outside of campus via network connections:

• Eduroam: we recommend using this encrypted WLAN via the international educational roaming service for users in research, higher education and further education

• Network access (cable) in public spaces: wired network access on campus.
• Network access at the workplace: everything you need for PC workstations on campus

Please note: in case you are using Windows XP, Windows Vista or Windows 7 we recommend using the → firewall integrated into the operating system. We would advise against installing an additional firewall software.

→ WLAN - further information: band width, cost etc

• Net access (via cable) in public rooms: tethered net access on campus

• Net access from PC workplaces: all necessary information about PC workplaces on campus
• Net access from outside of campus via VPN: work inside the campus net from anywhere
  
• Remote desktop: working from an off-campus workplace
