SFTP (Secure File Transfer Protocol)

SFTP (Secure File Transfer Protocol) is a protocol that allows you to securely transfer files to and from a remote server. Here are the basic steps to use SFTP to transfer files with a remote server:

1. Connect to the remote server: You can use a command-line tool such as the OpenSSH sftp client to connect to the remote server. The syntax is: sftp user@remote_server_ip_address or sftp user@remote_server_hostname.

2. Authenticate: Once you are connected, you will be prompted to enter your password for the remote server. Make sure you are entering the correct credentials.

3. Navigate the remote file system: Once you are authenticated, you will be in the remote server's file system. You can use the following commands to navigate the file system:

   • ls to list the contents of the current directory
   • cd to change directories
   • pwd to display the current directory

4. Transfer files: To transfer files to or from the remote server, you can use the following commands:

   • put local_file to upload a file from your local machine to the remote server
   • get remote_file to download a file from the remote server to your local machine
   • mput * to upload multiple files from your local machine to the remote server
   • mget * to download multiple files from the remote server to your local machine

5. Disconnect: Once you have finished transferring files, you can use the exit command to disconnect from the remote server.

Please note that this is a basic example and there are many other options that can be used with the sftp command. Also, make sure you have the correct permissions to access the files on the remote server and avoid overwriting any important files.

 

Here is an example of how to use SFTP to transfer files with a remote server:

1. Connect to the remote server:

sftp user@remote_server_ip_address

2. Authenticate:

password: *********

3. Navigate the remote file system:

sftp> ls
file1 file2 file3
sftp> cd /path/to/directory
sftp> pwd
/path/to/directory

4. Transfer files:

sftp> put local_file
Uploading local_file to /path/to/directory/local_file
local_file                                         100%  100     0.1KB/s   00:00
sftp> get remote_file
Fetching /path/to/directory/remote_file to remote_file
remote_file                                        100%  100     0.1KB/s   00:00

5. Disconnect:

sftp> exit

The above example shows how to connect to a remote server, navigate the file system, upload a local file to the remote server and download a remote file to the local machine. It's important to note that the SFTP protocol requires SSH access to the remote server, so make sure that the user has the correct permissions.
