Introduction
STinG Dialup Server is an IP dialup linkage server between your Atari and an external machine equipped with IP, Internet clients, and a modem.
It requires the presence of STinG and a modem.
Upon a ringing signal, the software picks up, requests authentication with a username ('Login') and a password ('Password'), and then assigns the dynamic IP address for the connection.
All server-client dialogue possibilities are then available between your 'local' Atari and the connected 'remote' machine.
The connection ends when there is no response to the ICMP test from the Packet Internet Groper (PING) and/or when the DCD signal of the modem drops if it allows it.
Configuration
Launch the software and in the 'Setup' menu configure:
2.1 Device
Choose the port, protocol, the desired 'local' IP address for your machine and the desired remote IP address as well as the 'maximum transfer unit' (MTU).
The addresses must be consistent with your IP routing file 'route.tab'.
By default, the proposed addresses are 192.0.2.1 and 192.0.2.2, which gives, for example, in the route.tab file:
# #Route for the 'dialups' dialup connection in the 192.0.2.xxx zone: # 192.0.2.0 255.255.255.0 Modem 2 0.0.0.0 # #Route for a Midi Intranet in a 192.0.1.xxx zone: # 192.0.1.0 255.255.255.0 Midi 0.0.0.0 # #Default route for a dialup connection to your #usual provider with distribution of this service # 0.0.0.0 0.0.0.0 Masquerade 0.0.0.0
MTU values are typically 1400 for SLIP/CSLIP and 1500 for PPP, but must remain the same as that of your provider in case of distribution by masquerade.
SLIP and CSLIP protocols have been tested with InterSlip for Macintosh.
To test the presence of the 'remote' machine you can enable the modem's DCD detection if it allows it, and/or check the network status by regularly sending a 'PING' signal (Packet Internet Groper) that the remote machine must return.
2.2 Modem
Place the command strings of your modem according to your documentation
- init: command sent at the launch of the software
- answer: pick-up command
- hangup: hang-up command
- reset: command sent before exiting the program
- NewLine: type of end of line, including for terminal mode.
Characters are used for special commands:
- '|': carriage return
- '~': 1-second pause
- 'v': DTR low
- '^': DTR high
2.3 User
Use the dialups.inf file to set the login, password and the maximum connection time (separated by a space) of users authorized for the connection.
ex:
;------- User file for dialups ------- ;login password maxtime in second or 0 for unlimited olivier 12345 60 res1 54321 7200
