Connecting to HPC-UGent
In order to connect to HPC-UGent infrastructure, you need to set up a VSC-id and a public/private ssh keypair.
How do I request a VSC-id?
- Navigate to https://account.vscentrum.be
-
Accept the certificate
-
Choose 'UGent' as Home Institution
-
Login, either using
-
your UGent account credentials
- your 'welkom' account credentials (for industry and other research institutes)
-
-
Upload your public ssh key by selecting the key file via the Browse button and click Submit
-
Once the key is uploaded, you will receive an e-mail
-
Click on the link in the e-mail to confirm your VSC-id request
-
You will receive another e-mail once your request is processed and your VSC-id is created
These steps are also described in Chapter 2 of the HPC-UGent tutorial.
How to create a public/private ssh keypair?
Windows
- Download the complete PuTTY package (free of charge) and install the package
- Start the PuTTYgen Key Generator
- Choose 'RSA' in the Parameters section at the bottom and keep the number to 4096
- Click 'Generate' and move the mouse cursor over the PuTTYgen window to generate random data
- Once the keypair is generated, set properties:
- Key comment - Fill in this field to make your keypair easier to identify later on. Choose for instance 'your_name@computername'.
- Key passphrase - Choose a passphrase to protect your private key against unauthorized use.
- Save both public and private ssh keys on your personal computer. We recommend using the names
- 'id_rsa.pub' for the public key
- 'id_rsa.ppk' for the private key
Linux / MAC OS X
- Open a Terminal
- Enter the command ssh-keygen -t rsa -b 4096
user@host:~> ssh-keygen -t rsa -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key ({HOMEDIR}/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): ********
Enter same passphrase again: ********
Two files are generate in the .ssh dir:
- private key: id_rsa
- public key: id_rsa.pub
These steps are also described in Chapter 2 of the HPC-UGent tutorial.
