NET::DNS

[Anonymous Monk]

On my windows machine I cannot get any of the examples from www.cpan.org to work. I know the module is installed correctly and there aren't any noticable errors in the code that my program or CMD will pick up. I looked through the docs and FAQs but it never said it can't work for Windows machines. The error I get is: query failed: connection failed for both snippets I tried. Anyone know what might be the problem or know of another module which might work?

Net::DNS has been broken on Windows for a while. I can't remember which version was the last to work though. You may want to try older versions from the Net::DNS website.

A few things:
• Is DNS set up correctly on your system? Do other DNS queries work? (e.g. can IE or Mozilla resolve www.cnn.com?)
• What version of Net::DNS are you using?
• What examples are you trying? What errors do they give?

• Yes, IE can go to websites.
• Version is 0.34
• One of the examples are

  #/usr/bin/perl -w
  
  use warnings;
  use strict;
  
  use Net::DNS; 
  my $rr;
  
    my $res   = Net::DNS::Resolver->new;
    my $query = $res->query("http://www.yahoo.com", "NS");
    
    if ($query) {
        foreach $rr ($query->answer) {
            next unless $rr->type eq "NS";
            print $rr->nsdname, "\n";
        }
    }
    else {
        print "query failed: ", $res->errorstring, "\n";
    }

Ok, by not working, does it print 'query failed', or does it die, or do something else? Is it possible you're behind a firewall, and just accessing the web through a proxy?

I needed Net::DNS myself, and even the earlier versions (0.12) didn't work on my Win2K Server box, so I tried to figure out what is wrong.

It looks like Net::DNS doesn't discover the name servers correctly. I added some code for both Win 95/98/Me as well as some (different) code for 2K / XP. Windows NT however should work as is.

You can find my patch attached to the corresponding RT ticket.
