Re^2: A weird problem while executing nmap and fetching its output

Thanks for your reply!

Well yes, -sU is slow, but on startup nmap prints a version info. Also, to be a bit more perl related, shouldn't while(<F>) read until an EOF?

So I suspect that the command doesn't execute at all, even though it is syntactically correct (if I print out the command and paste it to the commandline, everything works perfectly).

Is the whole open a command as a filehandle syntactic sugar for fork/pipe/execute so i can debug from there?
