What is SFTP and how does it differ from FTP?
SFTP, or Secure File Transfer Protocol, is a secure way to transfer files over a network that uses the SSH (Secure Shell) protocol to encrypt the data being transferred. This means that while using SFTP, both the commands and data are encrypted, providing a significant level of security compared to traditional FTP (File Transfer Protocol), which does not encrypt its data.
Unlike FTP, which uses multiple channels for communication and can send credentials in plain text, SFTP operates over a single encrypted connection, ensuring that sensitive information like usernames and passwords remain confidential during the transfer process. This added layer of security makes SFTP a preferred choice for businesses and individuals who need to safeguard their data.
How do I access SFTP from the Windows Command Prompt?
To access SFTP from the Windows Command Prompt, you will first need to ensure that you have an SFTP client installed on your Windows machine. Windows 10 and later versions come with a built-in SFTP client as part of the OpenSSH package. You can initiate a connection by opening Command Prompt and typing the command sftp username@host, replacing ‘username’ with your SFTP user ID and ‘host’ with the server’s IP address or domain name.
Once you enter the command, you will be prompted to enter your password. After successfully authenticating, you will have access to the remote server’s file system. You can use various commands in your SFTP session, such as ls to list files, get to download files, and put to upload files.
What commands can I use in SFTP?
In SFTP, you have access to several commands that help you manage files on the remote server. Commonly used commands include ls to list files and directories, cd to change the directory, get to download files from the server to your local machine, and put to upload files from your local machine to the server. These commands allow you to navigate and manipulate files effectively.
