Question

使用给定的代码段时，只会收到“目标无法访问”的回复（处理程序是来自https://github.com/volftomas/pyicmp的pyicmp.handler.Handler）：

     $return = array();
   if (!empty($contacts['feed']['entry'])) {
    foreach($contacts['feed']['entry'] as $contact) {

        //retrieve user photo
        if (isset($contact['link'][0]['href'])) {

            $url =   $contact['link'][0]['href'];

            $url = $url . '&access_token=' . urlencode($accesstoken);

            $curl = curl_init($url);

            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($curl, CURLOPT_TIMEOUT, 15);
            curl_setopt($curl, CURLOPT_VERBOSE, true);

            $image = curl_exec($curl);
            curl_close($curl);
        }
        $return[] = array (
            'name'=> $contact['title']['$t'],
            'email' => $contact['gd$email'][0]['address'],
            'image' =>$image,
        );


    }               
}

    foreach ($return as $contact) {

        $image=$contact['image'];
        echo $image;?>
        <br> <br> <br>
        <img  src="data:image/jpeg;base64,<?php echo $image ?>" /> <br>;
        <?php
    }

有些主机发送目标无法访问，其他主机阻止回应请求，我无法共享dumpfile因为dumpfile我现在拥有公司机构的IP映射。我可以通过Windows的def IPScanner(handler, ip, file, lock): for ttl in (32,): # putting 32 in a tuple was necessary here, # otherwise do_ping() acts as a noop ctr = 0 for j in range(0,4): t = PrintThread(str("Dest:" + ip + " TTL" + str(ttl)), lock) t.start() ping_result = handler.do_ping(ip, ttl) if ping_result['packet_loss'] == 0: ping_result['packet_loss'] = j break else: ping_result['packet_loss'] = 0 d = DumpFileThread(file, ping_result, lock) d.start() ping传递给该函数的IP。为什么我不能从pyicmp库接收ping。我的主机上没有阻止ICMP echo。

无法接收其他人的回复回复
