Follow the following procedures to setup an account for FAU clusters
We will ask you at some point to send us your 4K public ssh key, we will have one account per team.
$ 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 <user id>@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
