ICMP Socket类
实现ICMP协议的原始套接字,支持Ping和Traceroute功能。
主要功能:
在文件 icmp_socket.hpp 第 203 行定义.
ICMP消息类型常量
| 枚举值 | |
|---|---|
| ICMP_ECHO_REPLY | Echo Reply(Ping响应) |
| ICMP_ECHO_REQUEST | Echo Request(Ping请求) |
| ICMP_TIME_EXCEEDED | Time Exceeded(TTL超时) |
在文件 icmp_socket.hpp 第 209 行定义.

inlineexplicitnoexcept |
| void neforce::icmp_socket::open | ( | ) |
| ping_result neforce::icmp_socket::ping | ( | const ip_address & | dest, |
| milliseconds | timeout, | ||
| uint16_t | sequence = 0, | ||
| const void * | data = nullptr, | ||
| size_t | data_len = 0 ) |
执行Ping操作
| dest | 目标IPv4地址 |
| timeout | 超时时间 |
| sequence | 序列号(默认0) |
| data | 附加数据(可选) |
| data_len | 附加数据长度 |
发送ICMP Echo请求并等待响应,测量RTT。
引用了 neforce::data().
| vector< traceroute_hop > neforce::icmp_socket::traceroute | ( | const ip_address & | dest, |
| int | max_hops = 30, | ||
| milliseconds | probe_timeout = milliseconds(1000), | ||
| int | probes_per_hop = 3 ) |
执行Traceroute操作
| dest | 目标IPv4地址 |
| max_hops | 最大跳数(默认30) |
| probe_timeout | 每跳探测超时时间(默认1000ms) |
| probes_per_hop | 每跳探测次数(默认3) |
通过逐步增加TTL值探测网络路径, 收集每个中间路由器的IP地址和响应时间。
