Getting access

Once you have been onboarded, you should be able to access Klima using your University credentials.

Please be considerate of other users when running your jobs and workloads; There currently is no job scheduling or any other automatic resource limiting in effect.

SSH

  • From a terminal window, connect using SSH:

ssh <username>@klima.uod.otago.ac.nz

(Or use your favourite SSH client, specifying klima.uod.otago.ac.nz as the host.)

  • Authenticate using your University credentials.

FastX

FastX is a proprietary commerical remote desktop solution that allows users to run GUI applications or connect to a remote Linux desktop using a web browser on any device. It is a fast, low-bandwidth alternative to X2Go or other VNC solutions.

FastX is conveniently accessed via any modern browser: https://klima.uod.otago.ac.nz:3300 Alternatively a FastX native client can be used as well.

When running a full desktop, we recommend XFCE as it is the more lightweight window manager.

X2Go

The free & open source remote desktop application X2Go can be used to securely set up a graphical remote desktop session, in order to remotely run interactive GUI tools. X2Go provides much better performance than X11 forwarding or conventional VNC servers on Linux hosts, has inherent security, and supports advanced features (such as audio support).

Please refer to the X2Go website for installation and configuration instructions.

Non-default settings:

  • Host: klima.uod.otago.ac.nz

  • Login: <username>

  • Session type: choose XFCE as the window manager

Here are a few settings to tweak within XFCE that could resolve some issues we have come across before:

  • under Settings > Screensaver, turn off screen saver, and lock screen

  • under Settings > Power Manager: turn off System and Display power management

  • under Settings > Window Manager Tweaks, > Compositor; disable display compositing

Another problem you may run into: Stuck, suspended X2Go sessions may not get properly terminated, and cause reconnecting to fail. In that case, use SSH to login, and list the current X2Go sessions with x2golistsessions. The second field listed is the session identifier. Use this to terminate the session with: x2goterminate-session <session-identifier>.

RStudio Server

RStudio Server can be accessed at https://klima.uod.otago.ac.nz . Use your University credentials to login.

For more flexibility, RStudio Server can also be launched as a container .
