请大神们赐教ENC28J60模块的问题

ENC28J60模块作为客户端，为什么不能获取局域网网页的内容；
ENC28J60模块能ping的通，自己电脑能打得开，却获取不到内容；

#include <EtherCard.h>
static byte mymac[] = {0x00,0x1A,0x4B,0x38,0x0C,0x5C};
static byte myip[] = {192,168,5,106};
static byte gatewayip[] = {192,168,5,1};
static byte dnsip[] ={192,168,5,1};
static byte mymask[]={255,255,255,0};
static byte targetmac[] = {0x00,0x1A,0x4B,0x38,0x0F,0x5C};
byte Ethernet::buffer;
char website[] PROGMEM = "192.168.5.108:8080";//www.lucadentella.it
static uint32_t timer;
static void response_callback (byte status, word off, word len) {
Serial.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
Serial.println((const char*) Ethernet::buffer + off );
Serial.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<");
}

void setup () {
Serial.begin(57600);
Serial.println("MY C Demo");
if (!ether.begin(sizeof Ethernet::buffer, mymac, 53))
    Serial.println( "Failed to access Ethernet controller");
else
    Serial.println("Ethernet controller initialized");
// if (!ether.dhcpSetup())
//   Serial.println("DHCP failed");
// else
// {
    ether.staticSetup(myip,gatewayip);
    ether.copyIp(ether.dnsip,dnsip);
    ether.copyIp(ether.mymask,mymask);
// }
// Serial.println("DHCP configuration done");
ether.printIp("IP Address:\t", ether.myip);
ether.printIp("Netmask:\t", ether.mymask);
ether.printIp("Gateway:\t", ether.gwip);
ether.printIp("dnsip:\t", ether.dnsip);
Serial.println();
if (!ether.dnsLookup(website))
    Serial.println("DNS failed");
else
    Serial.println("DNS resolution done");
ether.printIp("SRV IP:\t", ether.hisip);
Serial.println();
}

void loop() {
ether.packetLoop(ether.packetReceive());
if (millis() > timer) {
    timer = millis() + 5000;
    ether.browseUrl(PSTR("/examples/servlets/servlet/"), "HelloWorldExample", "192.168.5.108:8080", response_callback);
}
}

提示的很清楚，dns failed，解析服务器的ip地址错。
手工设置下试试。

我只是访问局域网里的web，应该不用设置DNS也可以访问的啊，为何response_callback没输出信息呢？

真的很高科技，还没玩过网卡这部分。 帮你出点搜主义，试试其他网页的内容，比如外网的？这样至少排除了，你网卡盾和程序的问题，如果外网也出不来那就找程序的问题呗？

如果网线接在路由器上（路由器可以连接外网），这样可以输出web内容的，但是我需要没有外网的情况下输出局域网web的内容，好像不行，不知道能不能解决呢

瘦网虫 发表于 2014-2-21 15:58:47

端口问题吧。可能在enc28j60上设置端口不是这样的。表追问，我不懂，猜的。可以自己去看下库。

非常感谢，这个代码可以用，不过为什么输出的只是信息，而不是内容呢？
