Patrick-McMurphy is a PowerBook 150, with a 68030 at 33 MHz and 24 Mb of RAM.
which is a iMac G5 1.8 GHz running Mac OS 10.4.11 Tiger, sharing his ethernet connection as a PPP dial-up ISP server.
To do that one must first tell the iMac to forward IP packets, like so :
sudo sysctl -w net.inet.ip.forwarding=1
Then launch the native Mac OSX pppd daemon for a connection , like so :
sudo pppd 57000 tty.KeySerial1 local persist passive max fail 0 proxyarp 192.168.0.16:192.168.0.33
In order, this launches the pppd daemon at 57000 baudrate, through serial nmr 1 port of the KeySpan adapter, not using modem control line, with persistent connection, not dumping if client is not there, same, ARP table, then the IP of the serving machine (iMac G5) and IP of the ppp client (PowerBook 150).
Then on the PowerBook 150, set TCP/IP to FreePPP with a fixed IP (« Manually ») and your DNS, and set FreePPP to connect through the printer/serial port with no phone number at a 57000 baudrate. And hit connect.
