SFTP Data Transfer Protocol

Secure File Transfers with SFTP on AlexHost VPS

Why SFTP on AlexHost? SFTP (SSH File Transfer Protocol) is your go-to for securely moving files between your local machine and an AlexHost VPS. By leveraging SSH encryption, it keeps your data safe from prying eyes, unlike old-school FTP. With AlexHost’s robust Ubuntu VPS—complete with root access and DDoS protection—SFTP runs smoothly, making file management a breeze for your WordPress, Joomla, or custom projects. This guide breaks down how SFTP works, how to use it, and why it’s a must for secure transfers.

How Does SFTP Work?

SFTP works by establishing a secure connection between the client and server using SSH. Once the connection is established, users can transfer files, manage directories, and perform other operations just like traditional FTP, but with the added security of encryption.

Step 1: Setting Up SFTP

Most modern Linux distributions, including Debian and Ubuntu, come with OpenSSH installed, which includes support for SFTP. To ensure OpenSSH is installed, run the following command:

Step 2: Connecting via SFTP

To connect to an SFTP server, you need a client that supports the protocol. Some popular SFTP clients include FileZilla and WinSCP.

1. Using the Command Line (Linux/Mac): Open a terminal and use the sftp command:
   sftp username@hostname

   Replace username with your SFTP user and hostname with the IP address or domain of the server.

2. Using FileZilla (Windows/Linux):
   • Open FileZilla and enter the SFTP details (host, username, and password).
   • Set the protocol to SFTP instead of FTP.

Step 3: Transferring Files via SFTP

Once connected to the SFTP server, you can use basic commands to manage and transfer files:

• Put: Upload a file from your local machine to the server.
  put localfile.txt /path/on/server/
• Get: Download a file from the server to your local machine.
  get /path/on/server/remotefile.txt
• List Files: To list files in the current directory, use:
  ls

Advantages of SFTP

1. Security: SFTP encrypts both the authentication process and the data transfer, ensuring that sensitive information remains secure.
2. Firewall-Friendly: Unlike FTP, which requires multiple ports, SFTP only uses a single port (usually port 22), making it easier to manage through firewalls.
3. Integrated with SSH: Since SFTP runs over SSH, it benefits from all of SSH’s authentication methods, including password-based, key-based, and two-factor authentication.
