  • All our servers run Linux
  • You would usually log into our head (login node). It is called wonko.bi.up.ac.za.
  • Logging in directly to our compute servers is disabled. You need to run your jobs using the queueing system.
  • If you have a highly specific need to directly log in to one of the compute servers, please discuss it with our system administrator (johann.swart at up.ac.za).
  • An example from a Linux or Mac terminal session:
> ssh username@wonko.bi.up.ac.za

or if graphics forwarding is needed:

> ssh -X user@wonko.bi.up.ac.za
  • For Mac, XQuartz needs to be installed for graphics to work.
  • On newer versions of MacOS, you need to use:
> ssh -Y user@wonko.bi.up.ac.za
  • If you are logging in from a Windows machine, you can use a terminal emulator such as putty, BitVise or TeraTerm.
    • The hostname would be wonko.bi.up.ac.za, the user name would be the user name provided to you, and the authentication method would be password.
  • If you need to use graphics from a Windows client, you can download XMing.
