Hi I want to do some port checks (http and tcp) on an array of servers

I'm still new to Perl/Programming, and found in the perldoc Net::Ping, from which I have created some ping checks, along with code found on the net, but would like some guidance on how I could ping check and then test if some specific ports are available

I have created an array to ping some servers, which is fine, but Id like to create a sub function to check an array of ports. 

sub ping_servers {
        foreach $host (@my_servers) {
        my $p = Net::Ping ->new("icmp"); #create ping object
        my $res = $p -> ping ($host); #ping the hosts from array list
        $output .= "Unknown host $host\n" unless defined $resolve;
        if (!$res) {
                $output .= "$host doesn't respond to ping requests!\n"
+;
        } else {
                $output .= "$host is alive.\n";
        }

        }
}

I's also like to understand what this "->" means in code?

Any know how, or pointers would be great.
