Installing FTP Server (VSFTPD) on Ubuntu 22.04

An FTP (File Transfer Protocol) server in Linux is a service that allows users to transfer files between computers over a network. FTP servers are commonly used for uploading and downloading files, and they can be accessed via various FTP client applications.

Key Features of an FTP Server:

1. File Transfer: Facilitates the upload and download of files between clients and the server.

2. Authentication: Users can authenticate with a username and password, allowing controlled access to files.

3. Directory Listing: Users can view and navigate through directories on the server.

4. File Management: Supports operations like renaming, deleting, and moving files.

5. Passive and Active Modes: FTP can operate in active or passive mode, affecting how connections are established.

Step 1: Install VSFTPD Server

First, open your terminal and execute the following commands to install VSFTPD:

sudo apt update

sudo apt install vsftpd -y

Once installed, check the status of the VSFTPD service:

sudo service vsftpd status

This command ensures that the VSFTPD server is running correctly.

Step 2: Configure Firewall

To allow FTP connections, configure your firewall settings. Execute these commands:

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

These commands open the necessary ports for FTP communication.

Step 3: Create an FTP User

Next, create a dedicated FTP user to manage file uploads and downloads. Run the following commands:

sudo adduser ftpuser

sudo mkdir /home/ftpuser/ftp
sudo chown nobody:nogroup /home/ftpuser/ftp
sudo chmod a-w /home/ftpuser/ftp
sudo mkdir /home/ftpuser/ftp/files
sudo chown ftpuser:ftpuser /home/ftpuser/ftp/files

This setup creates a user directory structure that restricts write permissions for the main FTP directory.

Step 4: Configure VSFTPD

Backup the original configuration file before making changes:

 sudo mv /etc/vsftpd.conf /etc/vsftpd.conf.origin

Now, open the VSFTPD configuration file:

sudo nano /etc/vsftpd.conf

Modify or add the following settings to the file:

listen=NO
listen_ipv6=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
force_dot_files=YES
pasv_min_port=40000
pasv_max_port=50000

user_sub_token=$USER
local_root=/home/$USER/ftp

After saving the changes, restart the VSFTPD service to apply the new configuration:

sudo systemctl restart vsftpd.service

Step 5: Test FTP Connection

Log in to your client machine and run:

ftp ftp-server-ip

Replace ftp-server-ip with your server’s actual IP address. Log in with the ftpuser credentials you created earlier. If you connect successfully, your FTP server is ready for use!

Using WinSCP as a GUI FTP Client

1. • Open the WinSCP after installation.

2. Configure the Connection:

In the Login dialog, enter the following details:

File Protocol: Select FTP > Host name: Enter your server’s IP address > Port number: Enter 21 (default FTP port) > User name: Enter the FTP user you created (e.g., ftpuser) > Password: Enter the password for the FTP user

You should now be connected successfully!
