What's the best way to ping many network devices in parallel?

Question

I poll a lot of devices in network (more than 300) by iterative ping.

The program polls the devices sequentially, so it\'s slow. I\'d like to enhance the speed of pollin

Please give a try on "chknodes" parallel ping for Linux which will send a single ping to all nodes of your network. It will do also dns reverse lookup and request http response if specified so. It's written completely in bash i.e. you can easily check it or modify it to your needs. Here is a printout of help:

chknodes -h

chknodes ---- fast parallel ping

chknodes [-l|--log] [-h|--help] [-H|--http] [-u|--uninstall] [-v|--version] [-V|--verbose]

-l | --log Log to file -h | --help Show this help screen -H | --http Check also http response -n | --names Get also host names -u | --uninstall Remove installation -v | --version Show version -V | --verbose Show each ip address pinged

You need to give execute right for it (like with any sh/bash script) in order to run it:

chmod +x chknodes

On the first run i.e.

./chknodes

it will suggest to install itself to /usr/local/bin/chknodes, after that giving just

chknodes

will be enough. You can find it here:
