A bbs over decnet!

I found a simple c server and client program that was ported to decnet.  And it was easy enough to follow I thought I’d try something fun.  So I took Synchronet 3.00c and started to identify the winsock tcpip portions and then slowly alter them to either stubs or being more decnet friendly.

Surprisingly this wasn’t so hard.

The hard part is that decnet doesn’t have a telnet like protocol,  and I don’t have enough patience to try to reverse how ctermd works, so with a lot of searching I found a semi simple telnet client and mostly got it running on decnet.   Right now I have issues resolving address, so it is hardcoded.

I have to admit it was pretty cool to see the first connection, even though it aborted when it couldn’t figure out my ip address.   I made some more changes, and it worked!!

The next step was to fire up gns3 and build a simple 2 area decnet network and see if a NT box from area one could connect to a bbs in area two.  And with a few false starts I finally got a working multi area network (decnet isn’t like tcpip!!) This document on cisco’s site was invaluable.

As you can see this is pretty simple.  I wanted two serial connections so I could run DECnet on one serial connection, and TCP/IP on the other.  This way I could shut down the TCP/IP connection to ensure my conversation was 100% over DECnet.

As you can see the configuration is pretty simple.  I went with RIP because it’s a small network, and I only need a few routes.  EIRP, OSPF and friends are just pure overkill.  And recall VMNet8 is the NAT interface provided by VMWare Player.

Checking output from the routers, shows that DECnet is routing, and that I can ping both of my test NT boxes:

R1#show decnet route
Area Cost Hops Next Hop to Node Expires Prio
*1 0 0 (Local) -> 1.1
*2 20 1 Serial1/0 -> 2.1 44 64 A+

R1#ping decnet 1.3

Type escape sequence to abort.
Sending 5, 100-byte DECnet echos to atg 0 area.node 1.3, timeout is 5 seconds:

Everything is looking good! I fired up my DECnet telnet and success!!

Anyone crazy enough to want it can find the BBS on sourceforge, along with the telnet client.

And apparently he’s had far better luck getting the modems to operate well more like modems.  So no cheating as I did by using passive mode FTP to transfer QWK packets in & out of the system.  Its all very cool, and of course powered by OS/2 on Qemu so that makes me happy!

There isn’t a flash/java based page, so I’d recommend using syncterm.

Happy Y2K and beyond!
In support of the renewed interest in Synchronet BBS Software and it’s expectedtelnet capabilities some of you have been asking for registered versions of theold Domain Entertainment doors.  Instead, I’ve gone ahead and recompiled thesome of the doors (the games) so that they don’t require any registration.
Be aware that Domain Entertainment no longer makes, sells, or supports BBSdoors so use these at your own risk.  Domain Entertainment assumes no liabilityfor errors or omissions in these files or damages resulting from the use ofthem.
You may freely distribute this software so long as it is distributed in it’soriginal form with all accompanying files.

Wow that’s pretty cool!

So I’ve loaded it up on my BBS, and I’ve also updated the ‘bubble‘ BBS.

Although I don’t know poker for crap, any time I’ve won it’s with ‘neutral computers’ that don’t cheat. lol

The one interesting feature that fTelnet has is Ymodem-G support in the browser.  Sadly for the life of me I can’t figure out how to get it to work…

So for now if you want to try it, it’s available here on my test system…

I’ll have to detail the whole OS/2 on Qemu & Synchronet experience later.

Sorry for the bitrot stuff… At least I’m still here.

Also while working on Tradewars C today, I came across this great package called OpenDoors. Even better is that it’s under the LGPL. The only “downside” is that OpenDoors requires Visual C++ 6.0 or higher to build, because of the toolbar.. Also I’m not sure if going from VC 1.0 to 9.0 didn’t flake some stuff out as well… I’m not 100% sure about it, but the trading part of the game feels.. weird.

The examples are pretty straight forward, and it took a few hours on & off for me to convert the standalone tradewars into a door program. I like the feel of it so much I may try to see about converting SIMH to run with it.. Maybe even dumbfrotz.

Above is a picture of what the console looks like.

You too can download your very own BBS software here.

There is even a GREAT terminal emulator suitably named Syncterm that completes the experence. It supports rsh, telnet, ssh, x/y/z modem and cool ANSI graphics!
