        {page-number}: minor technical mistake
        <page-number>: important language/formatting problem
        (page-number): language change or minor formatting problem
        ?page-number?: reader question or request for clarification


Confirmed errors:


{33}  Chapter 10;
Chapter 10, the checkfile program, the extended version near the end of the chapter right below the line, "Let's extend our previous attribute-checking program to
include MD5:"

open(F,$savedstats[0]) or die "Unable to open $opt_c:$!\n";

should be:

open(F,$savedstats[0]) or die "Unable to open $savedstats[0]:$!\n";


[154] the line

	$/ = $recordsep;

should be added right before

	# read in database file



(262 & 265)
if ($successes == $machines){

should become:

if ($succeeded == $machines){



[370]  4th line from the end ;
The line read:

if (Net::PcapUtils::open_live(\&grab_ip_and_ping, FILTER => $prog));

it should be:

if (Net::PcapUtils::loop(\&grab_ip_and_ping, FILTER => $prog));
