pinguses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (``pings'') have an IP and ICMP header, followed by a “struct timeval” and then an arbitrary number of ``pad'' bytes used to fill out the pac...
1. 发送ICMP Echo请求:Send命令可以模拟Ping命令发送ICMP Echo请求。通过在终端中输入send IP地址,即可发送一个ICMP Echo请求并等待目标主机的响应。 2. 发送UDP数据包:Send命令可以通过指定目标IP地址和端口号来发送UDP数据包。例如,send -u -v -i IP地址 -p 端口号 -s 数据包大小可以发送一个UDP数据包。这...
fping is a program like ping which uses the Internet Control Message Protocol (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to pi...

The invention also proposes a method in which the Internet Protocol (IP) Address of the host behind NAT is included in the echo-request payload, thereby eliminating the need for storing this address in the mapping table at the NAT box. When the NAT Box receives the echo-reply back from ...

当在命令行中使用ping命令尝试向某个IP地址或域名发送ICMP回显请求(Echo Request)时,如果遇到“ping: sendto: socket is not connected”的错误信息,这通常表明在尝试发送数据包之前,网络层(通常是IP层)的socket连接没有正确建立或配置。然而,需要澄清的是,ICMP协议本身并不建立传统意义上的socket连接(如TCP连接),...

This function sends an ICMPv6 echo request and the call returns either immediately, if the Event or ApcRoutine parameter is non-NULL, or returns after the specified timeout. The ReplyBuffer contains the ICMP responses, if any.SyntaxCopy
傳回時,緩衝區包含ICMPV6_ECHO_REPLY結構,後面接著來自ICMPv6回應回應回復數據的訊息本文。 緩衝區必須夠大,才能保存至少一個ICMPV6_ECHO_REPLY結構,加上RequestSize參數中指定的數據位元組數目。 此緩衝區也應該夠大,以容納 8 個以上的數據位元組, (ICMP 錯誤訊息的大小) 加上IO_STATUS_BLOCK結構的空間。
