byte ip[] = { 10, 0, 0, 177 };

EthernetClient client;
 
void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
  client.connect(server, 80);
  delay(1000);
 
  Serial.println("connecting...");
 
  if (client.connected()) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}
 
void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }
