We are all living in a technological wasteland.


LegacyNET – Introduction


Just an introduction to one of my side projects.

One late evening I decided to get creative for a while. So I came up with the design for a semi-PaaS Windows 3.11 system.
Because it’s fun. I’ve always loved legacy systems because of their simplicity. Simplicity which allows me to grasp the history of complex current generation systems. The main purpose would be to see if I can meld old technology together with new technology.
It hasn’t been done before. At least not that I know of. And if I wanted to create an up-to-date system/design which would serve a business purpose, I would prefer to get paid for doing this. This is my spare time.
Gaming. You have to admit it, old-school games are fun. Anyone can download and install a DosBox and play Warcraft 2 games offline. However netplay on a server would be awesome.


This is the initial design I’ve had in mind, it lacks quite a lot of advanced features. The goal is to use as much out of the box components as possible. I don’t want to write my own servers or other components as this will take a huge amount of time and will likely not scale at all.


Front-end (http://legacy.enira.net)

This front-end GUI utilizes a regular HTTP/Apache2 web server to serve a graphical interface for users to:
a) Manage their account and credentials
b) Manage ‘friendly nodes’ which allow inter access network
c) Manage system messages and messages between users
d) Manage their virtual instance (reset/start/stop)

RDP gateway

This gateway is an Amazon EC2 instance (t1.micro) configured with HAProxy to proxy RDP connections to each instance and shield the node server from other external traffic. Each instance will receive an RDP port 3500 + n to connect.

Node 0

The actual physical system. In my case this will be an old Dell XPS M1530 which should provide enough resources for the initial setup.
Each VirtualBox instance will be configured with (based on a template):
– 32 MB RAM
– 100 MB of system storage (drive C:)
– 200 MB of user storage (drive D:)
– 800 x 640 resolution RDP connection
– Private IP address 192.168.x.100 + n connected trough an internet gateway (192.168.x.1)
– Windows 3.11 with networking capacities

A reset of an instance wipes drive C: (and repairs it from the template) but should keep all data on the D: drive.

Node Manager

Installed on each node, this manager allows JSON calls between the front-end component and physical state of the system. It will allow the GUI to send messages concerning:
a) System utilization
b) Instance management

Communication between node and front-end should be done using HTTPS and will utilize Apache2 to server HTTPS traffic.

Feasibility study

Study 1: RDP connection

Goal: Complete an RDP connection trough the internet and see if the performance of the RDP connection is enough for a Windows 3.11 instance running at 800×640. This RDP connection should use the VirtualBox RDP capabilities (found in the extra bundle).
Level: Critical
Status: Completed
Results: All objectives have been met.

Study 2: Clone template with VirtualBox

Goal: This test should create and maintain a new instance created from a previous Windows 3.11 instance (called template).
Level: Critical
Status: Ongoing

Study 3: Separate hosts on virtual LAN segment

Goal: This feasibility study should test if there is no traffic possible between each host configured in an internal networking mode. Preferably by using iptables and/ or Coyote Linux for routing network traffic.
Level: High
Status: Ongoing

Final notes

This system is far from perfect, and a lot of work needs to be done. I still need to confirm two feasibility statuses. If study 2 fails, this project will be scrapped.
This a project which is done entirely in my spare time the release date will be when it’s done.
