Here are some instructions for settings up VSFTP on UBUNTU (14.04 LTS). Assuming you are root, login and update apt-get:

apt-get update apt-get upgrade

Now install VSFTP

apt-get -y install vsftpd

Now you need to make a few edits to /etc/vsftpd.conf, uncomment, change, or add the following parameters:

anonymous_enable=NO
local_enable=YES
write_enable=YES
chroot_local_user=YES

Save and exit that file. Now, you shoudl create a new user which will only have access to FTP. I am creating a new user here because my current user is using a private key for login and I have SSH login disabled.

adduser <USERNAME>

Following the prompts UBUNTU gives you.

Finally, lets create a directory for to upload your files to:

mkdir /home/<USERNAME>/files
chown <USERNAME>:<USERNAME> /home/<USERNAME>

Restart the deamon:

sudo service vsftpd restart

Now use your favorite FTP client (FileZilla) or commandline to login and trasfer files.
