Access with SSH

amplitUDE

The login process using ssh is done with a 2FA-authentication (password + OTP-token). Thereby, the general OTP-token provided together with the UDE-account is used. Details see Information on two-factor authentication

For the access to amplitUDE the jump host login.hpc.uni-due.de is provided which provides load balancing across the frontend/login nodes of the cluster.

We recommend the following combined command for an interactive session (replace USERNAME with your lowercase USE account name):

ssh -t USERNAME@login.hpc.uni-due.de ssh amplitude

Alternatively, you can put

Host login-ampl
  HostName login.hpc.uni-due.de
  User [USERNAME]
  RequestTTY force
  RemoteCommand ssh amplitude

in your $HOME/.ssh/config on your local host machine and replace [USERNAME] with your UDE account name. Then you can use the short command ssh login-ampl to connect to amplitUDE. You will be asked for the user password and the OTP-token when logging in. Please note, the alias login-ampl can be individually choosen. But be carefully, that there can be collision with other aliases.

If you want to connect to the last connected frontend, then use this command

ssh -t USERNAME@login.hpc.uni-due.de ssh amplitude-last

If you need to a run graphical application, the -X option should be used, which enables X11 forwarding with X11 SECURITY extension. The complete command is

ssh -X -t USERNAME@login.hpc.uni-due.de ssh -X amplitude
