Access to the University Library's electronic resources (databases, e-journals) is possible if your computer has an IP-address which belongs to the RUB (these IP numbers have the following structure 134.147. * . *.) This is automatically the case if your computer is directly linked to the campus network.

Computers, which are located outside the campus network, only have access, if you dial into the internet via the campus data network of the RUB and in doing so are allocated an IP address of the RUB.
For this you need an access entitlement (RUB network user identification and password) [German] from the Computer Center.

Technical specifications

For the construction of such a VPN access you need programm OpenVPN-client, which is offerd by Network Operation Center (NOC), and a valid LoginId plus corresponding password from IT.SERVICES.

Due to the change of a server certificate on 31.03.2016 it is necessary to update the VPN client. The new, adapted OpenVPN-configuration data for windows (OpenVPN_RUB.ovpn) or Mac (, are provided on the NOC website ( The old configuration file should be deleted.

After configuration and start of the client you will be asked for your LoginID and the corresponding password. The VPN connection will be set up after these have been entered. Since the number of simultaneous VPN connections is limited, it is important to terminate the VPN connection immediately when it is no longer needed.

For access to library services requiring a license, the extension "bib" must be added to the LoginID (loginID.bib).

VPN access is offered by the NOC, supported by IT.SERVICES. If you have any questions, please contact the Service Center of the IT.Services.
