File transfers

How to transfer files to your Serverlet

Uploading and downloading files to and from a Serverlet is possible with SFTP (Secure File Transfer Protocol), which is implemented over SSH. This file transfer is always encrypted and secure. FTP (unencrypted transfer) and its encrypted variant FTPS (secure transfer) are not supported.

Every Serverlet has its own SSH server that handles the transfers. Transfer speed is therefore partly affected by the performance of the Serverlet, although even on the smallest plan it should not drop below an acceptable level. Every Serverlet also has its own port number for connecting. You will find your SSH port number in the administration on the Overview card of the Serverlet.

How to do it

You can use clients such as Filezilla or WinSCP for file transfers. Transferring with the scp command is possible as well. In this guide we will show the use of the Filezilla client.

1. Download, install, and start the Filezilla client.
2. Make sure the Serverlet is running.
3. Make sure you have set a password for the Serverlet user. The password can be set in the administration on the Users card of the Serverlet.
4. In the Host field enter the address in the form sftp://{physical-server-address}. The resulting address can look for example like this: sftp://serlo.futrou.com.
5. You will find the address of the physical server in the administration on the Overview card of the Serverlet.
6. In the Username field enter the name of the user. You will find the list of users in the administration on the Users card of the Serverlet.
7. In the Password field enter the password of that user.
8. In the Port field enter the SSH port of the Serverlet, for example 10022. You will find the port in the administration on the Overview card of the Serverlet.
9. Connect by clicking Quickconnect.

If everything went well, you should see the directories on the Serverlet in the right-hand part of the client. Your directory is /srv/.
