Question

How to install all dependencies of the module Nmap::Scanner with cpan in Perl? I did, cpan Nmap::Scanner. But, needing other dependencies for module.

  #!/bash/perl

  use Nmap::Scanner;
  my $scan = Nmap::Scanner->new();
  
  $scan->add_target('localhost');
  $scan->add_target('host.i.administer');
  $scan->add_scan_port('1-1024');
  $scan->add_scan_port('31337');
  $scan->tcp_syn_scan();
  $scan->noping();
  
  my $results = $scan->scan();
  
  my $hosts = $results->gethostlist();
  
  while (my $host = $hosts->get_next()) {
  
      print "On " . $host->hostname() . ": \n";
  
      my $ports = $host->get_port_list();
  
      while (my $port = $ports->get_next()) {
          print join(' ',
              'Port',
              $port->service() . '/' . $port->portid(),
              'is in state',
              $port->state(),
              "\n"
          );
      }
  
  }

I did, but when running the script in perl, shows this in console.

cpan resolves dependencies automatically. To install execute the following command:

cpan Nmap::Scanner

An alternative installer for CPAN modules is cpanminus. Using cpanm:

cpanm Nmap::Scanner
