​How to Use SFTP with FileZilla to Securely Transfer Files on RunCloud

In this tutorial, you will learn how to use SFTP with FileZilla to securely transfer and manage files on RunCloud server.

FTP is not secure

FTP (File Transfer Protocol) uses clear text for all transmissions. Anyone is able to read the FTP usernames, passwords, commands and data by packet capture (sniffing) on the network. By default, RunCloud Firewall blocks FTP (port 21) at your server. You are recommended to use SFTP for file transfer instead.

Tip: You can use RunCloud File Manager in RunCloud panel for simple file management.

SSH or Secure File Transfer Protocol (SFTP) is a secure file transfer protocol for file access, transfer, and management. It adapts the Secure Shell (SSH) protocol with encryption and secure authentication on both server and client.

SFTP provides two user-authentication options when connecting to your server: a)passwords or b)SSH2 key-based authentication. The SSH Keys is more secure than password.
