Let’s look at some of the best options that might be available for you:- 1. While it is not appropriate for every situation, it is a flexible tool to have in your repertoire.There are a number of options available to you when it comes to FTP clients. If you are used to using FTP or SCP to accomplish your transfers, SFTP is a good way to leverage the strengths of both.

For more information on this process, check out our tutorial on How To Enable SFTP Without Shell Access. When you are finished with your SFTP session, use exit or bye to close the connection.Īlthough SFTP is a simple tool, it is very useful for administrating servers and transferring files between them.įor example, you can use SFTP to enable particular users to transfer files without SSH access. Or execute a single command on the local system by prefacing the command with ! like so: If you need to perform these actions on the local file system, remember that you can drop into a shell by issuing this command: These commands replicate the basic behavior of the shell versions. The rest of the file commands target only the remote filesystem: SFTP allows you to create directories on both local and remote systems with lmkdir and mkdir respectively. Now all regular files downloaded (as long as the -p flag is not used) will have 644 permissions. This will display a list of the available commands: You can call it by typing either of these in the prompt: This gives you access to a summary of the SFTP help. The most useful command to learn first is the help command. This will connect you to the remote system by way of your specified port. sftp -oPort=custom_port your_server_ip_or_remote_hostname.If you are working on a custom SSH port (not the default port 22), then you can open an SFTP session as follows: You will connect the the remote system and your prompt will change to an SFTP prompt. sftp your_server_ip_or_remote_hostname.
Now we can establish an SFTP session by issuing the following command: Test SSH access with the following command: If you can connect to the machine using SSH, then you have completed all of the necessary requirements necessary to use SFTP to manage files.
Please see this guide to set up SSH keys in order to access your server if you have not done so already. This is much more secure and can save you time in the long run. Because of this, the same authentication methods are available that are present in SSH.Īlthough passwords are easy to use and set up by default, we recommend you create SSH keys and transfer your public key to any system that you need to access. How to Connect with SFTPīy default, SFTP uses the SSH protocol to authenticate and establish a secure connection. FTP is an insecure protocol that should only be used in limited cases or on networks you trust.Īlthough SFTP is integrated into many graphical tools, this guide will demonstrate how to use it through its interactive command line interface. In almost all cases, SFTP is preferable to FTP because of its underlying security features and ability to piggy-back on an SSH connection. The advantage is the ability to leverage a secure connection to transfer files and traverse the filesystem on both the local and remote system. SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way but over a secure connection. FTP, or “File Transfer Protocol” was a popular unencrypted method of transferring files between two remote systems.
