Configure SFTP access to your Ubuntu server through SSH

Sometimes you have to give your users a way to manage files on your server. A typical scenario is a web server where your users manage their websites by themselves.

  1. You have to provision and maintain a new service on your server;
  2. FTP is an annoying protocol from a firewall configuration point of view;
  3. FTP is not encrypted by default, and you have to put some effort to configure an FTP server which is protected from sniffing.

If you are a lazy sysadmin like me you’ll prefer to use a service you already have, which is encrypted by default and do not require a special firewall configuration other than the port 22 you are already using.
