HanRUN ethernet shield for Arduino
(first successfully run the following code on UNO compiled using 1.6.7 installed on HP INNOVA system)
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:

};

byte gateway[] = { 192, 168, 1, 1 };
// the subnet:
byte subnet[] = { 255, 255, 255, 0 };

// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);

Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// start the Ethernet connection and the server:

??? everything else work now ??? 1st tested network shield broke
1 - no booking or non-user
2 - booked but new user
3 - booked and registered user
