The Environment

The Environment

The systems at HPC2N predominantly run various versions of Linux. If you have no experience with that, there are several good online sources that can be used to familiarize yourself with the basic commands. 

Email

Email

Together with an account at HPC2N you will also get an email address. However, you cannot log in to read it at HPC2N so you will need to set up a .forward file pointing to your home/other email. This file will be used by HPC2N to determine where to send you any information.

The .forward file should only contain the email address you wish your mail sent to. A simple way to create this file is (after logging in to akka or other HPC2N cluster):

Shells

Shells

When your account is activated, your default shell will be set to bash - the GNU Bourne-Again SHell (bash), which is completely compatible with the Bourne shell (sh). For more details on bash, enter "man bash" while logged in.

SSH X11 Forwarding

SSH X11 Forwarding

In order to enable this, you must login with

ssh -X <username>@<host>

SSH supports tunneling of X11 (X-Windows). This is also very useful if you want to open graphical displays from the remote machine on your local computer. To achieve this, an X11 server must be running on your local machine. The X11 connections are then tunneled and automatically encrypted by your SSH client.

For some types of graphical software this does not work correctly (if they need input from keystrokes). In those cases you must use
