![]() ![]() What you are about to enter is what is called a Distinguished Name or a DN. You are about to be asked to enter information that will be incorporated Writing new private key to '/etc/ssl/private/vsftpd.pem' OutputGenerating a 2048 bit RSA private key Substitute your own information for the highlighted values: You’ll be prompted to provide address information for your certificate. sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/vsftpd.pem -out /etc/ssl/private/vsftpd.pem.By setting both the -keyout and -out flags to the same value, the private key and the certificate will be located in the same file: In the same command, add a private 2048-bit RSA key. Use openssl to create a new certificate and use the -days flag to make it valid for one year. The first step is to create the SSL certificates for use with vsftpd. Since FTP does not encrypt any data in transit, including user credentials, you can enable TLS/SSL to provide that encryption. ![]() Now that you’ve tested your configuration, next you’ll take steps to further secure your server. sudo chown nobody:nogroup /home/ sammy/ftp.In this example, rather than removing write privileges from the home directory, create an ftp directory to serve as the chroot and a writable files directory to hold the actual files. This is fine for a new user who should only connect via FTP, but an existing user may need to write to their home folder if they also have shell access. Since vsftpd secures the directory in a specific way, it must not be writable by the user. When chroot is enabled for local users, they are restricted to their home directory by default. vsftpd accomplishes this with chroot jails. Feel free to press ENTER to skip through the following prompts, as those details aren’t important for the purposes of this step.įTP is generally more secure when users are restricted to a specific directory. This guide outlines how to preserve an existing user’s access to their data, but, even so, we recommend that you start with a new dedicated FTP user until you’ve configured and tested your setup before reconfiguring any existing users.Īssign a password when prompted. However, you may already have a user in need of FTP access. In this step, you will create a dedicated FTP user. With vsftpd installed and the necessary ports open, now it’s time to create a dedicated FTP user. This output reveals that the firewall is active and only SSH is allowed through: If it is, then you’ll make adjustments to ensure that FTP traffic is permitted so firewall rules don’t block the tests. Step 2 - Opening the Firewallįirst, check the firewall status to see if it’s enabled. With a backup of the configuration in place, you’re ready to configure the firewall. When the installation is complete, copy the configuration file so you can start with a blank configuration, while also saving the original as a backup: You can find instructions for installing FileZilla on Debian and Ubuntu systems from this tutorial, along with links to instructions for installing it on other systems. This will allow you to test whether the client can connect to your server over TLS. The second thing you need is FileZilla, an open-source FTP client, installed and configured on your local machine. You can learn more about how to do this in our Initial Server Setup with Ubuntu 20.04 guide. The first thing you need is an Ubuntu 20.04 server, a non-root user with sudo privileges, and an enabled firewall. To follow along with this tutorial you will need: You’ll also connect your server using FileZilla, an open-source FTP client, to test the TLS encryption. In this tutorial, you’ll configure vsftpd to allow a user to upload files to their home directory using FTP with login credentials secured by SSL/TLS. vsftpd can handle virtual IPD configurations, encryption support with SSL integration, and more. It also provides strong protection against security problems found in other FTP servers. vsftpd is beneficial for optimizing security, performance, and stability. Vsftpd, very secure FTP daemon, is an FTP server for many Unix-like systems, including Linux, and is often the default FTP server for many Linux distributions as well. For example, Internet users who download directly from their web browser with https, and command line users who use secure protocols such as the scp or SFTP. If you have a choice on protocol, consider modern options that are more efficient, secure, and convenient for delivering files. FTP is still used to support legacy applications and workflows with very specific needs. FTP, which is short for File Transfer Protocol, is a network protocol that was once widely used for moving files between a client and server. ![]()
