ElWhip 0.07

This is a port of the lwip network stack and PPP over serial protocol for early Macintosh computers. It has been tested on a Macintosh SE running System 7.1 and a virtual Macintosh 128K with 64K ROMs. It will not be able to close the PPP session on quit on a Mac 128K due to memory limitations.

Web server configuration:

The web server does not require the HTML files to have the HTTP headers on the top. Only files with an extension will be loaded by the server (eg: ".html").

PPP configuration:

On Mac OS X 10.4 (and probably later):

/etc/ppp/options file:

asyncmap 0
proxyarp
lock

/etc/ppp/options.cu.usbserial file:

Replace cu.usbserial with the name of your serial device in /dev/ use the correct IP addresses for your setup

# Baud rate of the connection. ElWhip uses 19200.
19200
# Don't use the modem control lines.
local
# Try to reopen the connection it it is terminated.
persist
# Don't require the peer to authenticate.
noauth
# Disable negotiation of Van Jacobson style IP header compression.
novj
# IP address to be given to peer.
:192.168.11.130
# IP address of the DNS server for the peer.
ms-dns 192.168.11.1
# Enables IP forwarding on linux
ktune
# Add an entry for the peer to this system's ARP table.
proxyarp

Running PPP from the command line:

$ pppd -d cu.usbserial (Replace cu.usbserial with the name of your serial device)

Forwarding requests from LAN on Mac OS X:

$ sudo sysctl -w net.inet.ip.forwarding=1

Running ElWhip:

Just double-click the application once the modem port is connected to a computer running PPP. The application will try to negotiate a connection. Within a few seconds you should see the PPP phase increase to 7 and see the IP address information that was negotiated. A few seconds later, the web server will start.

Connecting to ElWhip:

From an appropriately networked computer, you can open a web browser and connect to the website.
