current_socket = socket.socket(socket.AF_INET，socket.SOCK_DGRAM，socket.IPPROTO_ICMP)

作为根I“回波1000 1000>的/ proc/SYS /网/的IPv4/ping_group_range”

我的组是1000

，我可以为我自己作为一个普通用户的身份运行ping.py，我可以看到echo请求和回应回复中tcpdump的

18:33:24.840291 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 269)

127.0.0.1 > 127.0.0.1: ICMP echo request, id 38, seq 0, length 249

18:33:24.840309 IP (tos 0x0, ttl 64, id 37939, offset 0, flags [none], proto ICMP (1), length 269)

127.0.0.1 > 127.0.0.1: ICMP echo reply, id 38, seq 0, length 249

但ping.py没有看到回复，并说超时。

任何想法如何使这项工作？

编辑：

我正在缩小这个问题。

print "c", icmp_header, address, self.own_id

if icmp_header["packet_id"] == self.own_id: # Our packet

问题是icmp_header [ “packet_id”]总是8247和self.own_id是ping.py.的PID 8247是十六进制的2037，我可以在转储中看到相当多的时间。

这是一个平的丝

AFAICT完全转储，ICMP报头可能被打包错误。然而它只是一个狂野的刺，我会在稍后再盯一下，同时，任何帮助将不胜感激。
