Re: [Simh] C9.io

[khandy21yo]

Do the free sites allow for constantly executing programs 24/7?
Another option into avoid network hacks is to go old school, and p.ug it into a 
dedicated phone line using a modem, if anyone has working modems any more.
Or get a second internet connection for this project,
Isn't this sort of thing usually done by placing the device in question outside 
of your firewall/net box?

I’ve only done network security for the last 12 years. So I’m not talking about 
the script kiddies using programs they’ve downloaded off the darker areas of 
the web. If a hacker really wants to get into your network, they will. Unless 
of course if you unplug it from the internet. 
But even regardless of the security issues, I just don’t want the traffic on my 
home network.  Which is why I’m trying to find somewhere to host it for free, 
so the simh is accessible from the internet. 
Since even if it’s very busy (which it likely wouldn’t be) the amount of data 
transferred would most likely be within the free tiers of some of the various 
VM hosting companies.

I’ve got the whole HECNET area 7 running on two ARM machines: a cubietruck and 
an Odroid-C1 that will get soon replaced by a Raspberry Pi model 3. 

I just allow HECNET access, no public internet one. Except for an ITS machine 
which responds to anyone trying to TELNET to my network, just for the laughs. 
And I password-protected the thing. If any sixties-seventies hacker wants to 
break into my network I will feel almost honoured ;)

First thing: configure SSH to be key-interchange based and disallow password 
logins. And the rest of the song: keep telnet closed (but you will have to keep 
it open to allow serial logins to your simh instances), don’t run anything as 
root (completely possible with simh 4.0 and VDE networking), and so on...

An alternative would be to use an old laptop, install a light linux bistro on 
it and use it to host your simh machines. It will run faster than an ARM (with 
a little bit more of power usage) but if the battery is still alive you’ll have 
a free UPS attached to your datacenter-in-a-box :)

Re: [Simh] C9.io

[Dave L]

opening any port on your firewall/edge router would make your IP open to  
probes tho, and you'd have to be sure the host you expose is secure so  
that other systems on your internal net isn't at risk. I guess you could  
place your host and guest on a separate vlan and place that into the DMZ  
with rules to allow internal to DMZ access to limit exposure.


Also make sure your router/firewall passwords are strong and not  
manageable from the DMZ. Dynamic DNS would mean you don't have to acquire  
a fixed external IP so you can then access via a DNS name rather than IP  
too.


Alternatively, make access via VPN only possibly with some of the above  
and not expose any open ports so you stay as invisible as possible on the  
web side...

Not quite that simple.  To expand on what I wrote previously: Typically,
machines inside your router trust each other.  In that case, once on the
Pi (or SimH guest), a user has access to anything else on your internal
network, unless you setup the right firewalls on each of your other
internal machines.  With a little care, it's not hard to setup a subnet
for the Pi & emulated machines that everyone else can distrust.

E.g. You open an ssh port to your Pi.  A user who ssh's to that Pi now
has a local address, and can ssh to your desktop - or browse for
Windoze/NFS shares - or whatever.  So you need to adjust the firewall on
your desktop to be very careful about what it permits from the Pi.  (And
guests on the Pi.)

It takes some thought to setup a moat around the Pi, but isn't
especially hard.  It does require a change in mindset from "everything
inside my router is more trustworthy than the outside" to "inside my
router is no guarantee, and access is case-by-case."

Note that the network stacks on the Guests probably haven't been updated
in a few decades, so while they will interoperate, they may have
exploitable bugs.  (Exploits never completely die...)

Re: [Simh] C9.io

[Dan Gahlinger]

a pi would do it.
and it's not opening it up
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

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

Just as an aside, Ray, I'm on HECnet and run several emulated systems 24/7

Re: [Simh] C9.io

[Joseph Oprysko]

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.

I know I’m able to build and execute it in the environment, but what I’d really

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?

I have been trying to figure out a solution for something similar to that.
I want to be able to run a PDP-11 outside of my house for Fortran
development. I would be running it on my Android phone.
