Answer by Nathan Osman for Basic Ubuntu FTP Server

I humbly recommend an FTP server I wrote myself from scratch: JetFTP. It is extremely simple to install and use.

Installation:

• Add my PPA to your software sources and update:

    sudo apt-add-repository ppa:george-edison55/george-edison

• Run the following command:

    sudo apt-get install jetftp

• That's it!

Using JetFTP is simple - just connect to port 8021 using a login name and password on the computer JetFTP is running on.
