ping a range of ips

English Programming/Scripting
#1

well if i need to ping a range of ips I can use a small script like this#!/bin/bash
for i in { 1…50}
do ping -c2 192.168.0.$i &> /dev/null
if $?=0 ]; then
echo “UP”
else
echo “DOWN”
fi
done

But I need to do this via a C program . How can I achieve the same ?

You can do this with Socket programming in C.
Are you familiar with C programming?
If you are not familiar with Socket programming, you may execute the “ping command” from within your C program and use the result in your program.

#3

You might want to look at the fping utility, which can do multiple pings in parallel and also allows you to specify the range on the command line.

Or nmap:

nmap -sP 192.168.0.1-50

The equivalent for my network scanned my entire class C in three seconds
(three hosts up, 251 down).

Good luck.

Kidding?
@tanmaya mentioned in his post that he wants to achieve the same stuff in C. I was responding to that. What is wrong with my response?
