So ive been dabbling alot with linux, And ive devised a way to get your
older machines online via serial.
To start you need a null modem cable or adapter
A TCP/IP Stack on whatever machine you decide to run on that supports
PPP. I run MiamiDX on the Amiga 2000, and Marinetti on the Apple IIGS.
Client Setup is like this
IP address:
Gateway: the IP address of your linux box
DNS: use the DNS servers of your ISP or use google public DNS
Basically all you need to do is install pppd in your favorite linux
distribution.
Then create a shell script that looks like this, Replace ttyUSB0 with
whatever serial port you are using. Replace 192.168.1.105 with the IP
address of your system, then replace 192.168.1.106 with the IP address
you plan to give your client system.
#!/bin/bash
sudo pppd debug -detach proxyarp persist 192.168.1.105:192.168.1.106
ttyUSB0 19200
Then fire up your client machine and you should be able to get right
online :)
Im going to do this on a RaspberryPi next so I can have a nice small box
to do what I need.
