Login to the Rackham console environment with a password¶
There are multiple ways to log in to Rackham. This page describes how to do so using a terminal and a password.
If you want to get rid of using a password every time, see login to the Rackham console environment with an SSH key.
Procedure¶

This procedure is also shown by this YouTube video.
1. Use ssh to log in¶
From a terminal, use ssh to log in:
[username] is your UPPMAX username, for example, sven,
resulting in:
-X enables so-called X forwarding,
which allows you to run programs that require light graphics,
such as eog to display an image.
Can I log in without -X?
Yes!
If you do not need X forwarding
to run programs that require light graphics,
omitting the -X is just fine.
Why no -A?
On Rackham, one can use -A:
this option is only useful when you want to
log in to Rackham via the console using an SSH key.
As we here use passwords (i.e. no SSH keys)
to access Rackham, -A is unused
and hence we simplify this documentation by omitting it.
2. Type your UPPMAX password¶
Type your UPPMAX password and press enter. You will see no asterisks to indicate how many characters you've typed in.
If you are outside the university networks you will be asked for your UPPMAX 2-factor authentication number.
3. You are in¶
Enjoy! You are in! Or, to be precise, you are in your home folder on a Rackham login node.
How to behave on a login node
On a login node, one can and should do simple things only: it is a resource shared with all other users on that node.
If you need to do more intense calculations, use the Slurm job scheduler.
If you need to do more intense calculations interactively, use an interactive node.
