Olá pessoal,
tenho uma dúvida relativamente simples, há qualquer tipo de software que possa bloquear a comunicação via Ethernet do Arduíno com um servidor Apache local?
Recentemente eu montei um servidor bem simplório para testar a comunicação entre meu Arduíno com ele, quando eu direciono para um servidor qualquer (google.com, por exemplo) ele funciona sem qualquer complicação, entretanto, quando direciono ele para um servidor local, ele simplesmente não abre comunicação, tentei com 2 códigos (sketches) distintos e mesmo assim não funciona.
Ambos os códigos são códigos exemplares da biblioteca "Ethernet".
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
//IPAddress server(74,125,232,128); // numeric IP for Google (no DNS)
// name address for Google (using DNS)
// Set the static IP address to use if the DHCP fails to assign
IPAddress ip(192, 168, 0, 17);
IPAddress myDns(192, 168, 0, 1);
IPAddress server (192,168,0,20);
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;
// Variables to measure the speed
unsigned long beginMicros, endMicros;
unsigned long byteCount = 0;
bool printWebData = false; // set to false for better speed measurement
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// start the Ethernet connection:
Serial.println("Initialize Ethernet with DHCP:");
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield was not found. Sorry, can't run without hardware. :(");
while (true) {
delay(1); // do nothing, no point running without Ethernet hardware
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println("Ethernet cable is not connected.");
}
// try to congifure using IP address instead of DHCP:
Ethernet.begin(mac, ip, myDns);
} else {
Serial.print(" DHCP assigned IP ");
Serial.println(Ethernet.localIP());
}
// give the Ethernet shield a second to initialize:
delay(1000);
Serial.print("connecting to ");
Serial.print(server);
Serial.println("...");
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.print("connected to ");
Serial.println(client.remoteIP());
// Make a HTTP request:
client.println("GET /arduino/webclient1.php"); // Dentro da pasta htdocs tem esta pasta com
client.println("Host: Localhost"); // o webserver dentro..
client.println("Connection: close");
client.println();
} else {
// if you didn't get a connection to the server:
Serial.println("connection failed AND I DON'T KNOW THE FUCKING WHYY!! GADMMITT!!!!");
}
beginMicros = micros();
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
int len = client.available();
if (len > 0) {
byte buffer[80];
if (len > 80) len = 80;
client.read(buffer, len);
if (printWebData) {
Serial.write(buffer, len); // show in the serial monitor (slows some boards)
}
byteCount = byteCount + len;
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
endMicros = micros();
Serial.println();
Serial.println("disconnecting.");
client.stop();
Serial.print("Received ");
Serial.print(byteCount);
Serial.print(" bytes in ");
float seconds = (float)(endMicros - beginMicros) / 1000000.0;
Serial.print(seconds, 4);
float rate = (float)byteCount / seconds / 1000.0;
Serial.print(", rate = ");
Serial.print(rate);
Serial.print(" kbytes/second");
Serial.println();

Erro da versão atualizada:
Erro da versão anterior:
Já desativei meu firewall (o que é improvavel já que o servidor ta de pé.), já botei meu ip local como DMZ (sei que não faz sentido em uma rede local, masvai que...)
