vsftpd – FTP Server Installation
sudo apt-get install vsftpd
I use nano to edit my text files. Use whatever you would like.
(read through the many options and uncomment or comment out what you would like to use)
I added this to the bottom of my conf file for security.
The ftpusers file is a list of users not allowed to use ftp. You can edit that file here.
Once you are finished use this command to restart vsftpd daemon.
By the way, I log in as root so no sudo command needed. If you are not logged in as root, then prepend each command above with sudo.
Here is a link to the official vsftpd install and setup guide on ubuntu.com
