+    ```console
+    marie@local$ ssh taurus.hrsk.tu-dresden.de
+    The authenticity of host 'taurus.hrsk.tu-dresden.de (141.30.73.105)' can't be established.
+    ECDSA key fingerprint is SHA256:PeCpW/gAFLvHDzTP2Rb93NxD+rpUsyQY8WebjQC7kz0.
+    Are you sure you want to continue connecting (yes/no)?
+    ```
+
+    In this case, the fingerprint matches the one given in the table. Thus, one can proceed by
+    typing 'yes'.
