FTP Access Guide

Connect your desktop tools (e.g., FileZilla, WinSCP, or Cyberduck) directly to the Nimbus file system for high-performance transfers.

Before You Begin

To ensure secure data movements, we enforce SFTP (SSH File Transfer Protocol). Standard FTP is not supported as it is insecure.

Active VPN

The SFTP server is only accessible while connected to the LiU-VPN.

SSH Key

We use Public-Key Authentication. Please share your public key (.pub) with the admin.

Approval

SFTP access must be manually enabled. Contact support for activation.

Connection Credentials

Use these settings in your preferred SFTP client (e.g., FileZilla, WinSCP, or Cyberduck).

Protocol
SFTP (SSH File Transfer Protocol)
Host
nimbus.research.liu.se
Port
22
Username
<your_username>
Auth Method
SSH Key File (Private Key)

Step-by-Step Setup

Option A: FileZilla (Windows / Mac / Linux)
  1. Open Site Manager (Ctrl+S or Cmd+S).
  2. Click New Site and name it "Nimbus".
  3. Set Protocol to SFTP, Host to nimbus.research.liu.se.
  4. Set Logon Type to Key File.
  5. Enter your username and browse to your Private Key file (often in `~/.ssh/id_rsa`).
  6. Click Connect.
Advanced 2FA Setup: For a more detailed guide on using FileZilla with Two-Factor Authentication (2FA), please refer to the Check NSC Guidelines here.
Option B: Command Line (CLI)

For automated scripts or Linux users:

sftp -i ~/.ssh/id_rsa <your_username>@nimbus.research.liu.se

Troubleshooting

Connection Timed Out

Usually indicates you are not on the LiU-VPN. Verify your VPN status and try again.

Authentication Failed

Check if you are using the correct Private Key that corresponds to the Public Key shared with the admin.

Permission Denied (During Upload)

Your folder ACLs might need adjustment. Contact us to reset the permissions for your workspace folder.
