Key Fingerprints

Hint

The key fingerprints of login and export nodes can occasionally change. This page holds up-to-date fingerprints.

Each cluster can be accessed via so-called login nodes using specific hostnames. All login nodes of a cluster share common SSH key fingerprints that are unique. When connecting to one of our HPC systems via the corresponding login nodes, please make sure that the provided fingerprint matches one of the table. This is the only way to ensure you are connecting to the correct server from the very beginning. If the fingerprint differs, please contact the HPC support team.

In case an additional login node of the same cluster is used, the key needs to be checked and approved again.

Connecting with SSH to Barnard
marie@local$ ssh login1.barnard.hpc.tu-dresden.de
The authenticity of host 'login1.barnard.hpc.tu-dresden.de (172.24.95.28)' can't be established.
ECDSA key fingerprint is SHA256:8Coljw7yoVH6HA8u+K3makRK9HfOSfe+BG8W/CUEPp0.
Are you sure you want to continue connecting (yes/no)?

In this case, the fingerprint matches the one given in the table. Thus, you can proceed by typing 'yes'.

Barnard

The cluster Barnard can be accessed via the four login nodes login[1-4].barnard.hpc.tu-dresden.de. (Please choose one concrete login node when connecting, see example below.)
