			With the launch of bwUniCluster 3.0, '''bwunicluster.scc.kit.edu''' no longer points to '''uc2.scc.kit.edu''' but to '''uc3.scc.kit.edu'''. In order to remove the warnings from your SSH client, you can delete the old hostkey as follows: <code>ssh-keygen -R bwunicluster</code>.

			For the sake of simplicity, '''we recommend using uc3.scc.kit.edu as the server address''': <code>ssh prefix_<username>@uc3.scc.kit.edu</code>

			Until 06.07.2025 the login to bwUniCluster 2.0 is possible analogously via <code>ssh <username>@uc2.scc.kit.edu</code>.


	In general, you should use automatic selection to allow us to balance the load over the three login nodes.		In general, you should use automatic selection to allow us to balance the load over the three login nodes.
