How To Create an FTP User for Your Web Server Using vsftpd

Ubuntu 8

FTP, or File Transfer Protocol, is a standard network protocol used for the transfer of computer files between a client and server on a computer network. In this guide, we will discuss how to create an FTP user for your web server using vsftpd, a fast and secure FTP server for UNIX-like systems.

Quick Answer

To create an FTP user for your web server using vsftpd, you need to configure vsftpd to enable local users and allow them to write to files. Then, create a new user using the useradd command and set a password for them. Finally, restrict the FTP user to their home directory for security purposes.

Prerequisites

Before we begin, make sure you have the following:

  • A Linux-based server with vsftpd installed. If you haven’t installed it yet, you can do so using the command sudo apt-get install vsftpd on Ubuntu or sudo yum install vsftpd on CentOS.
  • Root or sudo access to your server.

Step 1: Configuring vsftpd

First, we need to configure vsftpd to enable local users and allow them to write to files.

  1. Open the vsftpd configuration file with the command:
sudo nano /etc/vsftpd.conf

This command uses nano, a command-line text editor, to open the configuration file. You can replace nano with your preferred text editor.

  1. In the configuration file, find and uncomment the following lines by removing the # symbol:
local_enable=YES
write_enable=YES
chroot_list_enable=YES

Here’s what these parameters do:

  • local_enable=YES: This allows local users to log in to the FTP server.
  • write_enable=YES: This allows any FTP user to write to files.
  • chroot_list_enable=YES: This restricts users to their home directories.
  1. Save your changes and exit the text editor. In nano, you can do this by pressing Ctrl + X, then Y to confirm saving the changes, and then Enter to confirm the file name.

Step 2: Creating the FTP User

Next, we will create a new user who will have access to the FTP server.

  1. Use the useradd command to add a new user. Replace username with the desired username:
sudo useradd -m username

The -m option creates a home directory for the user.

  1. Set a password for the new user with the passwd command:
sudo passwd username

You will be prompted to enter and confirm the password.

Step 3: Restricting the FTP User to Their Home Directory

For security reasons, it’s a good practice to restrict FTP users to their home directories. This way, they can’t navigate to other directories on the server.

  1. Create a new file named vsftpd.chroot_list:
sudo touch /etc/vsftpd.chroot_list
  1. Open the vsftpd.chroot_list file and add the username of the FTP user:
sudo nano /etc/vsftpd.chroot_list

Add the username to the file, save your changes, and exit the text editor.

Step 4: Restarting vsftpd

Finally, for the changes to take effect, restart the vsftpd service:

sudo service vsftpd restart

Conclusion

That’s it! You’ve successfully created an FTP user for your web server using vsftpd. The user is now able to log in to the FTP server with their username and password and can write to files in their home directory.

Remember, FTP is inherently insecure because it transmits data in plaintext. Consider using SFTP (Secure FTP) or FTPS (FTP over SSL), which encrypt the data, for a more secure file transfer. You can enable SFTP or FTPS in the vsftpd configuration file.
