Setting Up an FTP Server on Ubuntu 20.04

Setting up an FTP (File Transfer Protocol) server on Ubuntu 20.04 can be a valuable skill, allowing you to efficiently share and transfer files over a network. In this guide, we'll walk through the process step by step, making it accessible even for those new to server administration.

Prerequisites:

Before we begin, make sure you have:

1. A system running Ubuntu 20.04.
2. Access to the terminal with administrative privileges.

Installing vsftpd:

Firstly, let's install the FTP server software, vsftpd. Open your terminal and enter the following command:

sudo apt update
sudo apt install vsftpd

Configuring vsftpd:

Once installed, we need to configure vsftpd to suit our needs. Open the configuration file with a text editor:

sudo nano /etc/vsftpd.conf

Now, uncomment or add the following lines to the configuration file:

write_enable=YES
local_umask=022

Save and exit the text editor.

Starting and Enabling vsftpd:

After configuring, start and enable the vsftpd service:

sudo systemctl start vsftpd
sudo systemctl enable vsftpd

Firewall Configuration:

If you have a firewall enabled, make sure to allow FTP traffic. Run the following commands:

sudo ufw allow 20/tcp
sudo ufw allow 21/tcp
sudo ufw reload

Creating FTP User:

For added security, it is recommended to create a dedicated user for FTP access. Replace 'username' with your desired username:

sudo adduser username

Assigning Permissions:

Give the new user appropriate permissions to access the FTP directory:

sudo chown -R username:username /home/username
sudo chmod 755 /home/username

Testing the FTP Server:

Now, it's time to test your FTP server. Open an FTP client on another machine and connect to your server using the assigned username and password.

Troubleshooting:

If you encounter issues, check the vsftpd logs for clues:

sudo journalctl -xe | grep vsftpd
