Setup - Cheap Cloud Storage EU

Initial setup uses secure shell (SSH) and consists of two parts:

1. Creating an account using your SSH key pair
2. Accepting Cheap Cloud Storage EU (CCSEU) terms of use

Accounts that have not accepted the CCSEU terms of use within one hour of public key upload may be deleted.

GNU/Linux and similar systems

Add the CCSEU certificate authority to your known_hosts file:
echo "@cert-authority *.cheapcloudstorage.eu ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIGd8Hl94FN5g8LNnawzpfofYy4ge8wPntT2m+cCCXZ5P" >> ~/.ssh/known_hosts
Optionally verify it using DNS:
dig ssh_ca1.cheapcloudstorage.eu txt +short

Create a new SSH key pair using OpenSSH:
ssh-keygen -t ed25519 -f ~/.ssh/ccseu -N '' -C ''
Do not lose above private key as you will not be able to access your account or your data without it. Support for key rotation is planned.

Derive your CCSEU username from your public key:
export ccseuname=u$(ssh-keygen -l -f ~/.ssh/ccseu.pub | cut -d: -f2 | cut -d' ' -f1 | tr +/ -_ | cut -c 1-19)

Upload your public key to create an account:
echo put ~/.ssh/ccseu.pub pubkeys/"$ccseuname".pub | sftp -P 897 -b - uploads@pod1.helsinki1a.cheapcloudstorage.eu

Your account should be ready within a few minutes, proceed by downloading the README file with instructions for accepting CCSEU terms of use to start uploading data:
echo get ccseu/README | sftp -P 897 -i ~/.ssh/ccseu -b - "$ccseuname"@pod1.helsinki1a.cheapcloudstorage.eu
