Login via SSH

Login via SSH


Text-mode remote access to the RWTH High Performance Computing is available over the secure shell (ssh) protocol. Where can be any of the dialog systems.


For example, for OpenSSH, the standard Linux ssh client:

$ ssh -l <your_userid>

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>

If your X11 application is not running properly try to use the (less secure) "-Y" instead of "-X" :

$ ssh -Y -l <your_userid>


SSH Fingerprints

You can find the fingerprints of the ssh host keys of our dialog systems here:  SSH Fingerprints of the Dialog Systems


The RWTH High Performance Computing 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.
