Login via SSH
Text-mode remote access to the RWTH Compute Cluster is available over the secure shell (ssh) protocol. Where cluster.rz.rwth-aachen.de can be any of the dialog systems.
For example, for OpenSSH, the standard Linux ssh client:
$ ssh -l <your_userid> login18-1.hpc.itc.rwth-aachen.de |
Instead of login18-1 you can use any of the dialog systems.
If you need to start graphical applications we recommend to use a remote desktop software. Alternatively, you can also enable X11 forwarding/X11 tunneling by your ssh client. For OpenSSH this is done by giving it the "-X" command line option:
$ ssh -X -l <your_userid> login18-1.hpc.itc.rwth-aachen.de |
If your X11 application is not running properly try to use the (less secure) "-Y" instead of "-X" :
$ ssh -Y -l <your_userid> login18-1.hpc.itc.rwth-aachen.de |

Accessibility
| The RWTH Compute Cluster is directly accessible only from the RWTH network and from other universities in North Rhine-Westphalia. In the latter case your computer additionally needs a valid DNS entry in order to get access. In all other cases you have to first establish a Virtual Private Network (VPN) connection in order to get an RWTH network address. |
