Access¶

The cluster is reachable inside the Münchner Wissenschaftsnetz (MWN). From outside the network you need eduVPN, or — for external collaborators — the jump host described below.

Connecting from inside MWN¶

$ ssh username@cluster.ginkgo-project.de

Note

There are known DNS issues over eduVPN and eduroam that we are working on with campus IT. If the hostname does not resolve, connect by IP:

$ ssh username@10.152.225.230

To change the SSH key on your account, open a Change SSH key ticket.

External users¶

External collaborators can log in through the jump host without a VPN:

$ ssh -4 -p 55841 username@comavm1.cit.tum.de

This entrypoint is only enabled for accounts flagged as external. A typical SSH config entry:

Host coma-cluster
    Hostname comavm1.cit.tum.de
    User username
    Port 55841
    AddressFamily inet
    IdentityFile ~/.ssh/id_rsa
    IdentitiesOnly yes

Then:

$ ssh coma-cluster
