How to configure FTP Server in Ubuntu using User authentication & anonymous

 What is FTP ?

File Transfer Protocol (FTP) is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections.

FTP is a client-server protocol that relies on two communications channels between client and server: a command channel for controlling the conversation and a data channel for transmitting file content. Clients initiate conversations with servers by requesting to download a file. Using FTP, a client can upload, download, delete, rename, move and copy files on a server. A user typically needs to log on to the FTP server, although some servers make some or all of their content available without login, also known as anonymous FTP.

sudo systemctl restart vsftpd

now if we refresh the above url we will find the user access upto providing the ftpuser with password

how to dump the file into url 

cd /home/ftpuser/

ls

examples.desktop

sudo mkdir share

sudo touch file
