Some fun networking with MS-DOS & Novell Netware.

Ok I wanted to do this eventually but now I’ve finally done it. I have constructed something a little complex but it works surprisingly well.

Let me draw a picture so it’ll be a little easier to follow:

All of the machines in clouds are virtual…

Ok I’m going to assume you can install & configure OpenVPN on your own. I did a really simple install on Proxmox VE, just be sure to use the e1000 network adapters. All the others gave me tones of errors with any sizable traffic. Also I should point out that I’m using OpenBSD 4.3 which is the latest as of today.

dev tun0
dev-type tap
ca /etc/openvpn/ca.crt
cert /etc/openvpn/server.crt
dh /etc/openvpn/dh1024.pem
key /etc/openvpn/server.key
server-bridge 192.168.6.33 255.255.255.224 192.168.6.50 192.168.6.62
push “route 192.168.6.0 255.255.255.0”
push “dhcp-option DNS 192.168.6.34”
client-to-client
duplicate-cn
keepalive 10 120
max-clients 100
persist-key
persist-tun
status /var/log/openvpn-status.log
verb 3
tun-mtu 1500
fragment 1300
mssfix
float

Again I just followed the example from the OpenVPN site to set this up. What makes this different though is the fact that I’m using this in a bridge mode. As you can see I have told OpenVPN that it is to use the tun0 interface as a ‘tap’ driver.

My hostname.tun0 is this:
Link0 up

Likewise the bridgename.bridge0 is:
add em1
add tun0
up

And finally for this example my bridgename.em1 is:
inet 192.168.6.33 255.255.255.224 NONE

So using this setup I have a ‘private’ 192.168.6.32/27 network in which I’ve got a few virtual machines running and space for my laptop to VPN into. Now one of the virtual servers on my Proxmox server is Windows NT 4.0 Terminal Server… Yeah I know I got it cheap on ebay, and I kind of like it. Anyways I’m running Qemu on it, which is running Netware 3.12. I installed the libpcap then I had to find out what my Ethernet devices are called. I used wireshark (it was ethereal) and it’s a cool program to have around. The last version to run under Windows NT 4.0 was 0.99.4 so that’s the one I used. Once I have done this I found my device and was able to setup a string for Qemu (which was \Device\NPF_RTL80291)

Here is what I’m using:

Qemu –had netware.disk –m 16 –M isapc –L pc-bios –net nic –net pcap,devicename=”\Device\NPF_RTL80291”

This sets up an ISA computer with 16 megaybtes of ram and a single ISA nic that will utilize libpcap to send out frames on the rtl80291 that’s being emulated to my NT terminal server by proxmox.

On the ‘client’ side of things, I’m running the 64 bit version of Vista. So I’ve installed the OpenVPN that not only has 64 bit device drivers, but has a nice little GUI to connect & disconnect from the networks. Here is the OpenVPN config that is on my laptop.

dev tap
ca ca.crt
cert client1.crt
key client1.key
client
proto udp
remote 192.168.1.75 1194
resolv-retry infinite
nobind
persist-key
persist-tun
;comp-lzo
mssfix
tun-mtu 1500
fragment 1300

Ok, so far so good. Now I do have Virtual PC 2007 on my laptop, and I have made sure that the “Virtual Machine Network Services” were bound to the “TAP-Win32 Adapter V9” interface.

The it’s a simple matter of connecting to the VPN, then loading up the virtual PC with MS-DOS & the Novell Netware client.

Then you should be able to ‘bind’ to the server & login!

The ‘cool’ thing about this setup is that it will work over things like wifi, and easily allow you to add clients near & far. Oh and the best part for the wifi crowd is that it will use REAL encryption since WEP/WPA have all been shown to be useless. Oh yes, and it should allow you to host your DOOM, Quake 1, Rise of the Triad, Warcraft II, and Descent games…. Along with people playing at home! Using this you too can build your own IPX/Internet network!

I do hope this clears some of the uses & versility of Virtual servers, Qemu & Virtual Networking.

What is there to tell? I’ve loved UNIX like things since I was first exposed to QNX in highschool (we had the Unisys ICONS!), and spent the better time of my teenage years trying to get my own UNIX… I should have bought Coherent in retrospect.. Anyways latched onto Linux in 1992, and then got some old BSD admin books and have been hooked on the VAX BSD & other big/ancient things since…!

  1. Hi
    I added one adapter in my VM and set it to be bridged and now I am trying to find a packet driver and network driver that will work in dos 6.22.
    or driver use your for vpc
    pls help

  2. you will need a netware client. Check your netware server disks for it….

    what version of server?

    not all clients work everywhere….

  3. i have an old pc that has a network drive by netware 3.12 in dos 6.22 . i backup hard disk by microsoft disk2vhd and now have an vhd file. i add vhd file in virtualbox and dos successfully boot. i can input server command, but when i input server command show this error:

    volume sys could not be loaded
    some or all volume segments cannot be located

    and virtualbox screen image:

    why this error show? netware was successfully work in my old pc but in virtualbox does not work,why?
