[Simh] C9.io

yes because hackers can do anything.
they can feed you a fake webpage and access your whole network.

there's no such thing as perfect security.
if that what you want you better stay offline.

any reasonable firewall can protect your system.

setup properly even if they break out of simh they are locked in a chroot jail.
and firewall on the device prevents them from getting anywhere.
with chroot you can take away their access to any standard utilities like telnet or ssh or anything too.

this is dirt simple and millions of people do it every day.

by again if you're that worried you better disconnect now.

uh oh look out 127.0.0.1 is attacking you...

I had the HP2100? Simulated on a Beaglebone Black for the Vintage Computer Festival a few years ago. I had an TI Silent 700 teletype connected to it. In a way it’s kind of a shame that a $35 (or $5 for a RPi Zero) is more powerful than the mainframes of old. Actually I have a couple of the Pi Zero W’s around somewhere. Computers used to be equipment to diagnose and repair down to the component and electrical trace level.  Now it’s literally throw away technology.

But even with an RPi running simh, it still needs to be on my home network, which is one of the things I’d like to avoid for the “Production Server” for lack of a better term.

As for not opening it up, I’m sure there’ll be someone who can figure out how crash out of simh and keep/get a shell running, and now they’re sitting on a machine inside my network with full access to my network.  And going through setting up a separate vlan or even having it go through a second router so it’s on it’s on it’s own network is more work than I’d rather do.

a pi would do it.

you open to just one port to just that pi
for just the pps

electric cost of a pi is peanuts.

cloud would cost you orders of magnitude more.

hell I run my own servers domain cloud etc

Dan, it is easy peasy, but not quite free, as if you want 24/7 access to the box, you have to keep the system running 24-7, so electricity costs. Plus, I’m planning on having others log in as well, thus I don’t want to open up my network like that. That’s why I’m looking for a free hosted/Cloud solution. That way someone else can deal with the rest of the network security. I do enough of that for work anyway, don’t want to have to monitor my home network as thoroughly.

Well, running from inside a house and making accessible from the outside is easy. But most ot my computers at home generally don’t run 24/7.

Mainly what’s needed for what we both want to be able to do isn’t really a shell account on a shared machine, but literally a dedicated VM instance, but we need to be able to access that instance through a public IP address.

On a home network, a private IP Address (192.168.x.x, 172.x.x.x ‘actually I don’t think it’s the whole 172 network’, or a 10.x.x.x) it’s easy enough to setup port forwarding to make it accessible. But on the Cloud based VM’s, I don’t know if there is a way to do it. Well, I know there ARE ways, usually involves paying for the instance, an external address, and possibly the amount of traffic.

Actually, I know Bluehost (is it still a thing?) used to  give you a VM with public address in combination with their hosting/domain name service.  But I’m hoping to find one that will not cost me anything.

Does anyone know if I can use the Cloud9 IDE to host a simh System emulation?

I know I’m able to build and execute it in the environment, but what I’d really like to achieve is to have a system (or several) running on various instances. And be able to connect to them from an external IP address, I believe I am able to SSH into an instance, or access it through the web based IDE.

An example might be better. Say I setup an HP system running Time-Share Basic. Would I be able to telnet to the TSB instance from various computers?

Thank you,

Joe
