Hello Perl Monks. I'm trying to make a portscanner that will take values from a MySQL database. I was able to make it without SQL support with this code:

%h;
$h{'Echo [Returns what is sent to server]'} = {service => ['7']};
$h{'Discard [A sink, like /dev/null]'} = {service => ['9']};

foreach $key(keys %h)
{foreach $service (@{$h{$key}{'service'}})
{if($khost=~/^$service/)
{chop($service) if ($service =~/\.$/);
print "\n[!] Port: [$start_port] Service: $key";
print O "[!] Port: [$start_port] Service: $key\n";
$start_port++}}}}}

Now I'm trying to do the same thing but with DBI. I have a table called "vulnerabilities" and I want to create a hash in perl, populated by the 'port', 'name', 'comment' that can be found on the vulnerabilities table. Untill now my code is something like this:

$sql = "select * from scanner.vulnerabilities";
    $sth = $dbh->prepare($sql);
    $sth->execute
        or die "SQL Error: $DBI::errstr\n";    
        
        my %ref;
        while (my $row = $sth ->fetchrow_hashref() ){
            $ref{ $row ->{'port'}} = $row ->{'Name'}
        }
        
        foreach $key(keys %ref)
            {foreach $port (@{$ref{$key}{'port'}})
            {if($khost=~/^$port/)
            {chop($port) if ($port =~/\.$/);
            print "\n[!] Port: [$start_port] Service: $key";
            print O "[!] Port: [$start_port] Service: $key\n";
            $start_port++}}}}}

The way it is does not working as it does not log the results. In small, I want to create a hash from MySQL that can do what the original program does. Although I have read a hell lot of resources it seems that I miss something. This program is for a college project and I cannot seem to be able to find the answer anywhere. Thank you in advance.
