Caution

This machine is for cpu-intensive jobs. Common jobs like editing, word-processing, graph or figure drawing, etc. should be avoided as far as possible.

Installation

You need to login to the server using SSH, also referred to as Secure Shell. The SSH protocol is a method to login securely from your computer (the “client” system) to a remote machine (the “server”) and transfer files between them.

MacOS

All modern Macs running macOS or Mac OS X come with SSH pre-installed by default.

Linux

Most Linux systems come with an SSH client preinstalled. A popular client is OpenSSH. To check whether OpenSSH is installed, run the following command in a terminal window which should give you the version of OpenSSH installed:

ssh -V

If you get an error informing you that the ssh command is not installed, you need to install OpenSSH. On Debian-based distributions like Ubuntu and Linux Mint this can be done using

sudo apt install openssh-client

Windows

On Windows, the simplest way to get SSH is to install Putty. Once Putty has been installed, you can Putty’s GUI to connect to the server as described in Logging in with Putty, or through Window’s PowerShell using the ssh command, as in Linux or MacOS.

Logging in

Setting up passwordless login

For security, a password-less connection should be used.
