fping命令

本文主要是介绍fping命令，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

fping是一个用于网络扫描的工具，它可以在 Linux 系统上使用。fping可以发送 ICMP ECHO_REQUEST（即 ping）数据包到指定的网络地址范围，并等待响应。通过这种方式，fping可以用来检测哪些 IP 地址是活跃的。

可以测试多个ip或者域名，并形成报告

[root@localhost ~]# fping 192.168.71.130 qq.com 192.168.71.131
192.168.71.130 is alive
qq.com is alive
ICMP Host Unreachable from 192.168.71.130 for ICMP Echo sent to 192.168.71.131
ICMP Host Unreachable from 192.168.71.130 for ICMP Echo sent to 192.168.71.131
ICMP Host Unreachable from 192.168.71.130 for ICMP Echo sent to 192.168.71.131
ICMP Host Unreachable from 192.168.71.130 for ICMP Echo sent to 192.168.71.131
192.168.71.131 is unreachable

192.168.71.130是可达的（alive）。
qq.com是可达的（alive）。
对于发送到192.168.71.131的ICMP Echo请求，从192.168.71.130收到了ICMP Host Unreachable错误。
192.168.71.131是不可达的（unreachable）。

指定范围

这里指定的是192.168.71.130到192.168.71.140在内的所有ip地址，并返回报告

[root@localhost ~]# fping  -s -g 192.168.71.130  192.168.71.140
