I posted a question up on Usenet a couple of years ago asking how to do non-blocking pings on Win32. I got some great answers, though none of them turned out to be practical.

Given that time has passed, and that I have discovered this superb website, I thought I'd ask again...

I have quite a few admin processes that ping (using Net::Ping) a list of 3000+ machines, and this can take a while. So I'd like to run them concurrently, say 10 at a time. That way timeouts don't slow things down so much.

Trouble with Net::Ping was that it blocked threads "fork()ed" in my script, and so ultimately only one ping ran at a time.

Question, then, is how do I get my scripts to ping these machines really fast? Preferably this would be without installing any non-core modules, and all inside a single script :)

Many thanks,

Gordon
