So, we showed you how to install and configure VSFTPD on Ubuntu 17.04 and 17.10. Today we’re going to show you how to install and configure ProFTPD. Both of these programs allow users to transfer files between the FTP client and server via FTP protocols.

There are many FTP servers one can use to provide FTP function. VSFTPD and ProFTPD are two of the most popular and probably the easiest to install and configure.

If you’re looking for a FTP server and VSFTPD can’t meet your needs, then give ProFTPD a try. You may find it to be useful. To install and configure ProFTPD on Ubuntu, follow the steps below:

Step 1: Install ProFTPD on Ubuntu

To quickly install ProFTPD on Ubuntu, run the commands below.

sudo apt-get install proftpd

The commands above install ProFTPD from Ubuntu repository. The server home directory is at /etc/proftpd and its main configuration file is at /etc/proftpd/proftpd.conf

sudo nano /etc/proftpd/proftpd.conf

Then make the highlighted changes below.

# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.

Step : Save your changes and restart.

The most important line in the configuration file is DefaultRoot    ~  This forces uses to only browse content in their home directory and no where else. When you’re done with the configuration, run the commands to restart the server and test.

sudo systemctl restart proftpd

Now open your FTP client and connect to the server hostname or IP address.

ubuntu proftpd setup

To deny users access to the FTP server, add their names in the /etc/ftpusers and save.

All users in that file won’t have access to the FTP server.

Enjoy!
