Hello monks, Do anyone use use Net::Frame::Dump::Online?

I am trying to use Net::Frame... modules for creation ICMP packets. For example ping request packet. I am trying to do this as it described in documentation on the CPAN. And it works for creation packet (i see it by sniffer) but also I need to get a replay packet in my script (this packet came to NIC as I can see in sniffer).
In this case for getting reply I have to use module Net::Frame::Dump::Online like this:

...
use Net::Frame::Dump::Online;
...
my $oDump  = Net::Frame::Dump::Online->new(
                dev             => 'eth0',
);
...
$oDump->start;

# And finally, waiting for the response
   until ($oDump->timeout) {
       if (my $recv = $oSimple->recv($oDump)) {
        print "RECV:\n".$recv->print."\n";
         last;
      }
   }
...

But it doesn't work..... the variable $recv is always undef ...

Please, if anyone know what can be issue here, help
