唤醒lan（php）无法让它工作

标签： php wake-on-lan

尝试在局域网上唤醒php（通过互联网）。

通过wolcmd程序，我可以使用命令从Internet成功打开服务器：

/Users/usr/Downloads/wolcmd [mac] [public IP] 255.255.255.255 1009

因此没有路由器/服务器问题。

我在互联网上发现了几个PHP脚本，但它们都没有用！ ：S

尝试：

<?php

flush();

function WakeOnLan($addr, $mac,$socket_number) {    
  $addr_byte = explode(':', $mac);
  $hw_addr = '';

  for ($a=0; $a <6; $a++) $hw_addr .= chr(hexdec($addr_byte[$a]));

  $msg = chr(255).chr(255).chr(255).chr(255).chr(255).chr(255);

  for ($a = 1; $a <= 16; $a++) $msg .= $hw_addr;

  // send it to the broadcast address using UDP
  // SQL_BROADCAST option isn't help!!
  $s = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

  if ($s == false) {
    echo "Error creating socket!\n";
    echo "Error code is '".socket_last_error($s)."' - " . socket_strerror(socket_last_error($s));
    return FALSE;
  } else {
    // setting a broadcast option to socket:
    $opt_ret = socket_set_option($s, 1, 6, TRUE);

    if ($opt_ret < 0) {
      echo "setsockopt() failed, error: " . strerror($opt_ret) . "\n";
      return FALSE;
    }

    if (socket_sendto($s, $msg, strlen($msg), 0, $addr, $socket_number)) {
      echo "Magic Packet sent successfully!";
      socket_close($s);
      return TRUE;
    } else {
      echo "Magic packet failed!";
      return FALSE;
    }
  }
}

// Port number where the computer is listening. Usually, any number between 1-50000 will do. Normally people choose 7 or 9.
$socket_number = "1009";
// MAC Address of the listening computer's network device
$mac_addy = "XX:XX:XX:XX:XX:XX";
// IP address of the listening computer. Input the domain name if you are using a hostname (like when under Dynamic DNS/IP)
$ip_addy = gethostbyname("name.dyndns.org");

WakeOnLan($ip_addy, $mac_addy,$socket_number)

?>

这个脚本给了我成功，但服务器没有醒来。另外，没有办法指定：255.255.255.255

我还尝试在我的笔记本电脑（而不是服务器）上使用数据包嗅探器，但我没有看到任何UDP包到达。

我尝试的另一个脚本是：

这里有问题的是$ deviceport =“1009”;如果我指定80它告诉我主机已关闭...但我已经知道了:)这就是为什么我正在发送魔术包？...

请帮助有经验的人吗？我没有想法尝试。

答案 0 :(得分：4)

您应该考虑使用这个简单示例脚本：

Mac：

<?php

system("/Users/usr/Downloads/wolcmd [mac] [public IP] 255.255.255.255 1009");

?>

或Linux：

<?php

system("wakeonlan arg1 arg2 ...");

?>

在Debian上安装此命令并派生：

sudo apt-get install wakeonlan

好吧，我已经清理了我的流程，这非常有效：https://github.com/wearede/wake-on-wan

<强>旧

现在有效！我只需访问子域名wol.domain.com :)就可以唤醒我的服务器。

经验教训：上面的脚本无法运行，因为我配置错误的路由器。从脚本中可以看出，正确的端口是1009.在路由器上我设置了传入端口1009将wihin lan重定向到端口9.由于某种原因（可能是因为它是UDP？）1009-＆gt; 9不工作。我做了1009-> 1009，服务器确实醒了！

我使用的最终代码：
