Results Scraping

Here is a simple Perl script (scrape.pl) which dumps out the open ports:

 #!/usr/bin/perl
 use strict;
 use warnings;
 use HTML::TableExtract;
 
 my $scan = "";
 
 {
      local $/=undef;
      open FILE, "ipv6.html" or die "Couldn't open ipv6 file: $!";
      $scan = <FILE>;
      close FILE;
 }
 my $te = new HTML::TableExtract();
 $te->parse($scan);
 
 my $pingtable = $te->table(0,0);
 my $udpporttable = $te->table(0,1);
 my $tcpporttable = $te->table(0,2);
 
 # Ping result
 foreach my $row ($pingtable->rows)
 {
      foreach my $ele ( @$row )
      {

# ICMPv6 ECHO REQUEST returned : ECHO REPLY

              if (defined $ele)
              {
                      if ($ele =~ m/ECHO(.*)REPLY$/)
                      {
                             printf("PING response was %sREPLY\n",$1);
                      }
              }
      }
 }
 
 # Currently prints out the OPEN ports
 foreach my $row ($udpporttable->rows)
 {
      foreach my $ele ( @$row )
      {
              # Port 7 = RFSD
              if (defined $ele)
              {
                      if ($ele =~ m/Port\s+(\d+)\s+=\s+([A-Z]+)/)
                      {
                              my $port = $1;
                              my $state = $2;
                              if ($state =~ m/OPEN/)
                              {
                                       printf("UDP PORT %5d was %s\n",$port,$state);
                              }
                      }
              }
      }
 }
 
 foreach my $row ($tcpporttable->rows)
 {
      foreach my $ele ( @$row )
      {
              # Port 7 = RFSD
              if (defined $ele)
              {
                      if ($ele =~ m/Port\s+(\d+)\s+=\s+([A-Z]+)/)
                      {
                              my $port = $1;
                              my $state = $2;
                              if ($state =~ m/OPEN/)
                              {
                                       printf("TCP PORT %5d was %s\n",$port,$state);
                              }
                      }
              }
      }
 }

Typical Scraped results

 $ ./scrape.pl
 PING response was  REPLY
 UDP PORT   123 was UDPOPEN
 TCP PORT    80 was OPEN
 TCP PORT   443 was OPEN
