Install Anonymous FTP server on CentOS 8

FTP (File Transfer Protocol) is used to transfer computer files between client and servers on a computer network. FTP users can authenticate themselves with a username/password, but FTP users can also connect anonymously, if the FTP server is configured to allow it.

In this lab, we will install and configure Anonymous FTP Server on CentOS 8.

Here, configurations are performed through Linux CLI (Command Line Interface). Therefore, we strongly recommend you should read The Linux Command Line, 2nd Edition by William Shotts, to develop a strong understanding of Linux CLI.

Connecting with CentOS 8 based Anonymous FTP Server:

To connect to an FTP server, we need a FTP client.

There are many free FTP clients available on the Internet and in CentOS 8 yum repository.

We are installing lftp (A sophisticated FTP Client) to connect with our FTP server.

[root@ftp-client ~]# dnf install -y lftp
