Welcome to our comprehensive guide on Linux FTP server. In this article, we will cover everything you need to know about Linux FTP server from installation to configuration and troubleshooting. Whether you are a beginner or a professional, this guide will provide you with all the necessary information to set up and maintain a Linux FTP server. So let’s get started!
1. Introduction to FTP Server
FTP (File Transfer Protocol) is a standard protocol used to transfer files between computers over a network. An FTP server is a software application that runs on a server and provides access to files on that server through FTP. Linux is a popular platform for running FTP servers because it is reliable, secure, and customizable.
In this section, we will discuss the basics of FTP server and how it works.
1.1 How does FTP Server work?
FTP server works on the client-server model. The client sends a request to the server for connecting to it and sending or receiving files. The server then responds to the client’s request, and the file transfer starts.
FTP uses two channels for file transfer: the control channel and the data channel. The control channel is used for sending commands and responses between the client and server, while the data channel is used for transferring files.
FTP uses different modes for transferring files, such as ASCII and binary mode. In ASCII mode, the file is transferred as text, while in binary mode, it is transferred as a binary file.
1.2 Advantages of using FTP Server
FTP server offers several advantages over other file transfer methods. These advantages include:
| Advantages | Explanation |
|---|---|
| Reliability | FTP is a reliable protocol for transferring files over the network. |
| Security | FTP provides several security features such as encryption, authentication, and access control. |
