向子网上的每个 IP 发送 ping [英] Send a ping to each IP on a subnet

问题描述

是否有基于命令行的方式来向子网中的每台计算机发送 ping?喜欢

Is there a command line based way to send pings to each computer in a subnet? Like

for(int i = 1; i < 254; i++)
    ping(192.168.1.i);

强制解析arp?

推荐答案

我建议将 fping 与掩码选项一起使用，因为您不会限制自己使用 ping.

I would suggest the use of fping with the mask option, since you are not restricting yourself in ping.

fping -g 192.168.1.0/24

响应将很容易在脚本中解析:

The response will be easy to parse in a script:

192.168.1.1 is alive
192.168.1.2 is alive
192.168.1.3 is alive
192.168.1.5 is alive
...
192.168.1.4 is unreachable
192.168.1.6 is unreachable
192.168.1.7 is unreachable
...

注意:使用参数 -a 会将输出限制为可访问的 ip 地址，您可能需要使用它，否则 fping 也会打印无法访问的地址:

Note: Using the argument -a will restrict the output to reachable ip addresses, you may want to use it otherwise fping will also print unreachable addresses:

fping -a -g 192.168.1.0/24

来自人:

fping 与 ping 的不同之处在于您可以指定任意数量的目标在命令行上，或指定一个包含目标列表的文件平.而不是发送到一个目标，直到它超时或回复，fping 将发送一个 ping 数据包并移动到下一个以循环方式定位.

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 ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.
