Hi,
I was wondering, how does Smokeping know if there are loss packets ?
Because i'm getting results from smokeping that tells me my Owamp probe got
19/20 packet lost.
Thank you very much,
Luc

The open() function with a pipe ('|') executes the specified
command, and its output can be read from the opened filehandle.
See the perlfunc and perlipc manuals for details.
open(P, "$cmd 2>&1 |") or croak("fork: $!");
