vsftpd [Very Secure File Transfer Protocol Daemon] is a popular FTP server for Ubuntu. we will install and configure vsftpd on Ubuntu 18.04 / 19.10. 

*** Install vsftpd

sudo apt update && sudo apt install vsftpd

sudo service vsftpd status

*** Configure Firewall

sudo ufw allow OpenSSH
Open ports 20 and 21 for FTP, and ports 40000-50000 for passive FTP.also open port 990 for TLS.

sudo ufw allow 20/tcp
sudo ufw allow 21/tcp
sudo ufw allow 40000:50000/tcp
sudo ufw allow 990/tcp

***Enable the firewall if it isn’t already. Press y and ENTER if warned about disrupting the SSH connection.

sudo ufw enable

***Check the status of the firewall :

sudo ufw status

***Create FTP User


 ** Now create a new user that we will use to log into FTP. In this example, we will create a new user called ftpuser.
this user not fixed you can change .

sudo adduser ftpuser

*** Now Generate a strong password and keep it safe You can just press ENTER to each of these.

**Open the SSH config in nano.

sudo nano /etc/ssh/sshd_config

# Add the following to the bottom of the file replacing ftpuser with the user you want to deny SSH and SFTP access. You can add multiple users here separated by a single space. (To paste in nano, press the right mouse button) and save it.
# DenyUsers ftpuser

*** Restart the SSH service.

sudo service sshd restart

***Upload to a Web Server

Let’s set the folder above the document root as the home directory for ftpuser.

sudo usermod -d /var/www ftpuser

***This will allow our FTP user to write and alter files in the document root directory.

sudo chown ftpuser:ftpuser /var/www/html


***Upload to a Home Folder

sudo mkdir /home/ftpuser/ftp

***Set the ownership of the ftp directory to no nobody:nogroup.

sudo chown nobody:nogroup /home/ftpuser/ftp

sudo chmod a-w /home/ftpuser/ftp

*** we will create a new directory within /ftp where the user can view and upload files.

sudo mkdir /home/ftpuser/ftp/files

**Assign ownership of this directory to our new FTP user otherwise they will not be able to write to it.

sudo chown ftpuser:ftpuser /home/ftpuser/ftp/files
