Day 8 : How to Configure an FTP Server on CentOS
FTP (File Transfer Protocol) is a standard network protocol used for transferring files from one host to another over a TCP-based network, such as the Internet.
FTP is widely used to upload, download, and manage files on remote servers.
Here’s a detailed overview of FTP, including its workings, types, security, and usage.
PermalinkOverview of FTP
Purpose: FTP is designed to facilitate file transfer and management, allowing users to share files across different computers and platforms.
Client-Server Model: FTP follows a client-server architecture where:
FTP Client: The software used by a user to send and receive files.
FTP Server: The server that stores files and handles requests from clients.
PermalinkHow FTP Works
PermalinkConnection Establishment
FTP operates over two separate connections:
Control Connection: Used for sending commands and receiving responses. It typically operates on TCP port 21.
Data Connection: Used for transferring files. This can operate on various ports, depending on the mode (active or passive).
PermalinkCommon FTP Commands
Here are some commonly used FTP commands:
Command | Description |
USER | Specify the username for authentication. |
PASS | Specify the password for authentication. |
LIST | List files and directories in the current directory. |
RETR | Retrieve (download) a file from the server. |
STOR | Upload a file to the server. |
DELE | Delete a file on the server. |
PWD | Print the current working directory. |
CWD | Change the working directory on the server. |
