From within the University (intranet)
Within the internal net of the University, access to the systems is granted via ssh. Use your favorite ssh client like OpenSSH, PuTTY, etc. For example, on a UNIX/Linux system, users of FLOW may type on the command line (replace "abcd1234" by your own account):
ssh abcd1234@flow.hpc.uni-oldenburg.de
Similarly, users of HERO login by typing:
ssh abcd1234@hero.hpc.uni-oldenburg.de
Use "ssh -X" for X11 forwarding (i.e., if you need to export the graphical display to your local system).
For security reasons, access to the HPC systems is denied from certain subnets. In particular, you cannot login from the WLAN of the University (uniolwlan) or from "public" PCs (located, e.g., in Libraries, PC rooms, or at other places).
From outside the University (internet)
First, you have to establish a VPN tunnel to the University intranet. After that, you can login to HERO or FLOW via ssh as described above. The data of the tunnel are:
Gateway : vpn.uni-oldenburg.de or vpn2.uni-oldenburg.de Group name : hpc-vpn Group password: hqc-vqn
Cf. the instructions of the IT Services on how to configure the Cisco VPN client. For the HPC systems, a separate VPN tunnel has been installed, which is only accessible for users of FLOW and HERO. Therefore, you have to configure a new VPN connection and enter the data provided above. For security reasons, you cannot login to FLOW or HERO if you are connected to the intranet via the "generic" VPN tunnel of the University.
