Starting out
To build your own private network you really don't need a Unix machine or a big
Pentium with Windows NT. All that's needed are two Atari machines with STinG installed.
A lot of people already have STinG
installed on there Atari, so I think that I don't need
to explain how you should install
STinG.
If you don't know how to connect your Atari to the Internet using STinG,
you should stop reading this and first go to the STinG
homepage to download the documentation on this.
Chose the connection
When you have two Atari's with a STinG
setup, the first thing to do is choosing the connection
type between the two machines. Let's say we want to connect a Falcon to a TT030. We can use the midi ports
for this. But if we are going to use the connection a lot we may choose for a faster connection. The modem
to modem connection for example. Most people will chose for the fastest possible connection. On a ST this
is mostly the midi port. The Falcon, TT030 and Mega STe have modem2/serial2 ports. These ports
have higher speeds than the midi port.
IP addressing
After you have build the network with the hardware it's time to think
about the software. Lets start with the addressing. Every machine in the
network should have it's own unique number. The IP address. If you are not
going to connect your network to the internet the numbers you can assign
could start at 0.0.0.1 for the first machine, 0.0.0.2 for the second, 0.0.0.3
for the third etc.
But most (private) networks will connect to the internet in some way.
If you have assigned number(s) from previous example, it's possible that these
numbers already exsist on the internet resulting in "strange" behaviour or
not working at all. Therefore it's better to use special reserved numbers. The
192.168.x.x is one of these. it's reserved for private networks.
The "x" in the number can be anything from 0 to 255.
Now start assigning number by writing them down. For my own network I
have assigned 192.168.50.01 to the TT030 and 192.168.50.32 to the Falcon.
Other numbers are possible of course.
Below is a table with all major settings of my own network between the Falcon and the TT030.

192.168.50.1 |
Route table(s)
Now we have to modify the routing tables on all machines. The routing
table is a plain text file that tells STinG where to send what.
This file can be found in the STinG module folder and is called "ROUTE.TAB".
Open this file in a text editor. Qed or Everest will do fine.
The route table on the Falcon
| destination | subnet mask | port | gateway |
| IP's at the Falcon |
| 192.168.50.32 | 255.255.255.255 | Internal | 0.0.0.0 |
| IP's at the TT |
| 192.168.50.01 | 255.255.255.255 | Modem 2 | 0.0.0.0 |
| default route |
| 0.0.0.0 | 0.0.0.0 | Modem 2 | 0.0.0.0 |
The yellow text are comments. It is not a actual part of the route desciption.
The first line tells STinG that all data send to IP:192.168.50.32 should go
to the internal port. Thus it should not go to another machine at all. The
second line tells STinG that all data send to IP:192.168.50.01 should be send
to the Modem 2 port. If you have a midi connection between the two machines
then it should be Midi. The last line tells STinG that all other data should
be send to the Modem 2 port. The names used for the ports are the same as found
in the STinG port cpx. Note that the names can be different on different machines!
The last line should always be the so called 'default' route.
The route table on the TT030
| destination | subnet mask | port | gateway |
| IP's at the Falcon |
| 192.168.50.32 | 255.255.255.255 | Modem 2 | 0.0.0.0 |
| IP's at the TT |
| 192.168.50.01 | 255.255.255.255 | Internal | 0.0.0.0 |
| default route |
| 0.0.0.0 | 0.0.0.0 | Modem 2 | 0.0.0.0 |
The yellow text are comments. It is not a actual part of the route desciption.
The route table from the TT030 is almost the same as the Falcon. Only
the ports are different.
|
Now you have modified the route tables it's time to set the IP Addresses.
So get your note you made when you assigned the IP numbers and open the port
cpx from STinG. Go to the port you want to use and the assigned IP address
in the port cpx. And don't forget to make it active.
|
 |
 |
After setting the IP address click on addressing and
go to general. Set here the desired protocol. If this
is done, save the settings. Activate "Reload Routing Table" And
click "OK"
|
|
Now go to the STinG Internals cpx and make sure that STinG is active.
If not, make it active and save the settings.
|
 |
Repeat this on all machines that you what to connect to
the network. Don't forget that all machines have their own IP address.
Another thing you should remember is to use the correct protocol. If the
Falcon modem2 is connected to the TT030 modem2 and both machines have
different protocols assigned, the connection will not work correct.
Testing the connection(s)
To test a connection you can use the STinG dialer. Just open the dialer
and select 'PING' from the tools menu.
 |
|
Fill in the IP address from the machine you want to reach. For example
we want to test the connection between the Falcon and the TT030 using the
Falcon. So we fill in the IP address from the TT030 and click 'OK'.
|
|
Another window will now appear showing what happens. If you have done
every thing right the ping will work and you have a real network.
|
 |
Often a connection does not work at first attempt. Check everything
in your settings. Most often a connection does not work due to human
errors. (It already costs me hours to look for small typing error).
