If you want to access stderr, look at the ruby api docs for popen3.
It's a little more complicated than the backticks but it'll get you
access to stderr.

No it looks like the back-ticks will be fine

I have this in a loop

results = `ping -s #{bytes} -c 1 -D #{host}`


the code runs fine localhost and on my godaddy IP hoever it blows up on
another site. But I am not confident I am doing this right so How can I
tell if its my code or a valid black-hole MTU?

Thanks

"blows up" in what way?

I know that was not very descriptive. I meant to say that the ping its
self failed. I think it is a couple of things none of which is an
error.

1.) The target host blocked pings after a certain count example Site5
does this.

2.) My ping loop is running to fast at which point the host declines and
the ping fails

3.) It's a black hole which is what we are trying to detect.

It looks good now I have it working for Linux, Unix, OS X, BSD, and
Windows...


Thanks you all for your help. Oh I'll share code if anyone is
interested. Not a big deal .. . .
