                An attempt at demystifying the process of setting up sftp access to an EC2 instance on AWS, provisioning restricted access to folders (specifically webroots). This should also work on RHEL or most other UNIX flavours, with little changes. There's no claim to perfection however. All execution must be carefully done. Messing around with sshd_confi…

    Ubuntu 16.04 on AWS EC2

This guide enables desktop mode in Ubuntu 16.04 (Xenial Xerus) running off an AWS EC2.
Setup


Launch an EC2 instance with Ubuntu 16.04 (should work on all versions greater too)
Ensure a security group is configured, that allows ingress on ports 22 (SSH) and 5901 (VNC, 5900+N, where N is the display number)
SSH into the instance, update the system, install the XFCE desktop and the lightweight VNC server:
