An FTP server allows you to transfer files between computers over a network. vsftpd (Very Secure FTP Daemon) is a popular FTP server for Unix-like systems. This tutorial will guide you through installing and configuring vsftpd on a Linux server.

Prerequisites

• A Linux server (e.g., Ubuntu or Debian).
• Access with sudo privileges.

Step 1: Install vsftpd

Update the package list and install vsftpd:

sudo apt update
sudo apt install vsftpd -y

Step 2: Backup the Configuration File

Before making changes, back up the original configuration file:

sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak

Step 3: Configure vsftpd

Edit the vsftpd configuration file:

sudo nano /etc/vsftpd.conf

Modify the following settings:

• Uncomment local_enable=YES to allow local users to log in.
• Uncomment write_enable=YES to allow write permissions.
• Uncomment chroot_local_user=YES to confine users to their home directories.

Add the following line to enable passive mode (adjust the port range as needed):

pasv_min_port=40000

Allow FTP traffic through the firewall:

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

Step 7: Test the FTP Connection

Use an FTP client like FileZilla or the command line to connect:

ftp your_server_ip

Log in with the ftpuser credentials.

Step 8: Secure the FTP Server (Optional)

For enhanced security, consider:

• Using FTPS: Configure SSL/TLS encryption.
• Limiting User Access: Restrict users to specific directories.
• Disabling Anonymous Access: Ensure anonymous_enable=NO is set.
