Re: How to aggregate output of NMAP

Quoting Lodin, Steven {GZ-Q~Mannheim} (STEVEN.LODIN_at_Roche.COM):
> Someone else mentioned Perl and gave a small code example. If this is interesting to you, check out ndiff (Nmap diff). I don't have the URL, but if I remember correctly, I found it from one of the nmap mailing list archives on www.insecure.org.

I mailed this to the original poster... It does what I think he wanted....

#!/usr/bin/perl -w

$NmapLog = './bla';
$look4 = qr/ftp|http|echo/;
# ^^^^^^^^^
# add more sevices you want to create summary for

open (IN, $NmapLog) or die "open $NmapLog err: $!\n";
while (<IN>) {
  chomp;
  $ip = $1 if /^Interesting\sports\s.*\((.*)\):/;
  push @{$phash{$&}}, $ip if /$look4/;
}
close IN;

foreach ( keys %phash ) {
  $num = scalar @{$phash{$_}};
  print "\'$_\' open on $num server", (($num == 1)? undef : 's'),
        " : ", (join ', ' , @{$phash{$_}}), "\n";
}

Sure. Well, I REALY feel like writing perl code today....

Nah. Just roll your own :)
