Request Server Access

This section gives an overview on how to request access to our upload server to submit data from outside of the University Tübingen network.

Tip

Should you be a member of the university of Tübingen you can immediately upload your data and skip this process.

Prerequisites

  • An ed25519 encrypted public and private keypair on the connecting machine
  • The static and public IPv4 address of the connecting machine
  • The name and affiliation of the data submitting party

Procedure

To minimize security risk, access to our upload server is restricted to temporary whitelisted IP addresses from outside of the university network.

Note

Please make sure to provide a public and static IP address from the machine you want to connect from. Check with your IT department on details on how to obtain such an IP address.

As an additional security layer, data submitters have to authenticate using strong cryptographic keys. Once these technical details are resolved, feel free to contact us to request access to our server

Generate Cryptographic Keys

For account creation a public key is required. Please generate an ssh keypair via your system specific command and make sure to specify your email address:

Open your terminal 

ssh-keygen -t ed25519 -a 420 -f ~/.ssh/qbic-upload.ed25519 -C "<your_email@example.com>"

Open Terminal as described by Apple 

ssh-keygen -t ed25519 -a 420 -f ~/.ssh/qbic-upload.ed25519 -C "<your_email@example.com>"

Open PowerShell as described by Microsoft 

ssh-keygen -t ed25519 -a 420 -f $HOME/.ssh/qbic-upload.ed25519 -C "<your_email@example.com>"

with the name qbic-upload.ed25519 and a public key named qbic-upload.ed25519.pub within your .ssh directory.

Get in Contact

After you have generated your ssh key and setup a public static IP address, please write an email to support@qbic.zendesk.com and attach the public (.pub) key file similar to the provided template:

Warning

Make sure you only send us the public key file ending with .pub

Do not send us the private key!
