Follow the following procedures to setup an account for FAU clusters
Try and login to https://portal.hpc.fau.de/ with your university name (Use “Another institution” button)
In case there are missing attributes, you will need to contact the local university that part of eduGAIN.
In case you can not find your university, please let us know ASAP so we can handle this.
We will collect one email address (university email that can be login to eduGAIN) per team to create the account, you will receive the invitation. That email address should be able to login via eduGAIN.
After login on the portal-> User tab : You will need to upload your 4K public ssh key to the portal. You can upload multiple keys per team/user.
$ ssh-keygen -t rsa -b 4096 ... $ cat .ssh/id_rsa_4k.pub
2. Once we will supply the access, you will need to login to the server with your given username.
Setup your ssh config file to make it easier:
$ cat .ssh/config
Host fau
HostName cshpc.rrze.fau.de
IdentityFile ~/.ssh/id_rsa_4k
User <user id>
3. Login to fau clusters
$ ssh fau .....
4. Setup public-key in your environment on FAU login node.
$ cd .ssh $ ssh-keygen ... $ cp id_rsa.pub authorized_keys
5. Login to Fritz or alex clusters
