I am using the following sketch to test my new Ethernet shield, but it does not compile, giving errors see below) :
//zoomkat 12-08-11, combined client and server
//simple button GET with iframe code
//for use with IDE 1.0
//open serial monitor and send an g to test client and
//see what the arduino client/server receives
//web page buttons make pin 4 high/low
//use the \ slash to escape the " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
#include <SPI.h>
#include <Ethernet.h>
//changed this section :
//byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
//IPAddress ip(192,168,1,102); // ip in lan
//IPAddress gateway(192,168,1,1); // internet access via router
//IPAddress subnet(255,255,255,0); //subnet mask
//IPAddress myserver(208,104,2,86); // zoomkat web page
//EthernetServer server(84); //server port
//changed to :
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address

I have the Ethernet and SPI libraries in place as they were installed when I originally installed the Arduino IDE.
Suggestions please.
