Introduction: An FTP server allows connected users to download, upload, and navigate the directories of files stored on the server. After this server setup is complete, you will be able to access the FTP server via terminal, or by using its credentials in an FTP client like FileZilla or Cyberduck. We'll use vsftpd as well

Introduction: Big business and small startups alike, servers form the core infrastructure of any tech company. If you're setting up those servers yourself, you'll want to make sure you're doing it right.
