Re: DNSSSEC verification example

[Adam F. <a...@br...>]

Hi Brian- How do I modify the initial request message to request the
DNSSEC extended attributes? Should I be able to get those attributes
from a query to say gmail.com -- i.e can I just fire off queries to
bunch of the major sites at this point and expect DNSSEC responses?

Thanks very much.

-Adam

Thanks very much, Brian -- this is super useful. I've been trying to
avoid breaking out the RFCs, but it sounds like I've just been in

There isn't really a such thing as "a DNSSEC response", so I'm not completely sure what you're looking for.  DNSSEC signs DNS records, not DNS messages.

A response from a signed zone will (typically) contain one or more RRSIG records, signing the data records, which comprise an RRset.  If you have the public key (which won't be in the response), 
then you can call DNSSEC.verify(rrset, rrsig, pubkey).  The data and signature RRsets can be obtained from Message.getSectionRRsets() on the response, and the matching signature can be found by comparing the results of getFootprint() on the public key (DNSKEY) and signature (RRSIG).

I don't think it's possible to come up with a quick example of all of this, as it's not trivial.

Can anyone provide a quick example of verifying a DNSSEC response on the
client side. I can't seem to find good documentation on how to do this.

Thanks very much in advance.

Re: Possibility to extend the Zone class

[Lucas F. <li...@sa...>]

Hello Brian,

Thanks for you prompt answer.

I agree that introducing an interface may break backwards
compatibility. But a way to allow users to define their own Zone
mechanism would be great. In the end, I had to alter the visibility of
several fields in the Zone class and the SetResponse class.

If you can think of another solution, I am willing to spend a few
cycles to help.

Regards,

Lucas

Possibility to extend the Zone class

[Lucas F. <li...@sa...>]

Hello,

I am working on a project based on dnsjava (actually, I am trying to
extend Eagle DNS) and need to publish a zone which is too big too fit
in memory, so I need to extend the Zone class.

While woking on this, I am having problems because the Zone
findRecords method must return a SetResponse object. Unfortunately,
the SetResponse constructors and set methods are only available inside
the org.xbill.DNS package, which makes it impossible to extend the
Zone class without altering the dnsjava jar file.

So, I have a couple of questions/suggestions:

1. Is it possible to make dnsjava more extensible by providing Zone as
an interface, so users may provide their own Zone implementations?

2. Is it possible to make the SetResponsible constructors and setters
available to external classes?

Thanks,

Lucas

That there's a bug in dnsjava.  I just committed a fix, which will be in the next release.

It would have been easier to find if your sample code had been complete, though.  The problem only occurs when there's existing data in the cache, so just attempting to run that code didn't fail.

IllegalArgumentException : oneElement(ANY)

[Niel de W. <ni...@gm...>]

Hi All,

I've got this simple lookup:

	String domain = "test.surbl.org";
	String dnsblDomain = "multi.surbl.org";
	Lookup lookup = new Lookup(domain + "." + dnsblDomain, Type.ANY);
        Resolver resolver = new SimpleResolver();
        lookup.setResolver(resolver);
        Record[] records = lookup.run();

Trying to do a look up of DNS blacklists. However, at the last step an
IllegalArgumentException occurs with the message "oneElement(ANY)". I
find this very strange, since the documentation of the constructor says
"Throws:
        IllegalArgumentException - The type is a meta type other than
        ANY."

What does this execption tell me? Am I missing something crucial?

On the command line I do the following to test:
$ host test.surbl.org.multi.surbl.org

Kind Regards

how to bind a local socket address beforing sending a lookup request?

[邓悟 <de...@ta...>]

My using scenario is very simple:
Before looking up A type record, I want to bind a local socket address.


// here, is there any way just like socket.bind(SocketAddress sockAddress), that lets me  bind a socket address?

Lookup l = new Lookup("u.ecctest.com",Type.A);

I've never pushed any releases to maven central, as I don't use maven.  I don't know who put 2.1.1 (or any other version) there, but perhaps whoever did will add the new version.

how to retrieve resource records and other stuff

[Periya.Data <per...@gm...>]

Hi,
     I have a DNS packet and I want to retrieve the entries in the query
section, answer section, name server resource records and additional records
sections. I see several approaches in the DNS Message library. I have not
yet attempted to run this code. Currently building the templates carefully.


Here is what I am doing and would like to know if there are better/elegant
approaches:

// dns_msg.getQuestion() returns the first record in the Q section.

        Record[] dns_query_record_array =
dns_msg.getSectionArray(Section.QUESTION);

        // dns_query_record_array.length must be equal to qdcount
        if (dns_query_record_array.length == 0) {
            // do something.
        } else {
            // do something...maybe print to verify
            int i = 0;
            while(i < dns_query_record_array.length) {
                //
                Record dns_query_rec = dns_query_record_array[i];
                System.out.println("Resource Record: " +
dns_query_rec.rdataToString());

                if (dns_query_rec != null){
                    Name qname = dns_query_rec.getName();
                    String qname_s = qname.toString();
                    int qtype = dns_query_rec.getType();
                    int qclass = dns_query_rec.getDClass();
                }
                i++;
            }

        }

       // Will the above get me all the entries in the question section? Or
should I do something like below..?????

        /*
      Record queryRecord = dns_msg.getQuestion();
        for (int q=0; q < qdcount; q++){
            if (queryRecord != null){
                qname = queryRecord.getName();
                qname_s = qname.toString();
                qtype = queryRecord.getType();
                qclass = queryRecord.getDClass();
            } else {
                qname_s = "none";
            }
        }
    */

        // DNS Answers
        // Note: there will be ANCOUNT number of resource records. You have
to loop to
        // get all the entries of the answer section.

        char rdlength;
        char rdata;

        Record[] dns_answer_record_array =
dns_msg.getSectionArray(Section.ANSWER);
        if (dns_answer_record_array.length == 0) {
            // do something.
        } else {
            // do something...maybe print to verify
            int i = 0;

                int rdata_class = dns_answer_rec.getDClass();
                long ttl = dns_answer_rec.getTTL();

                i++;
            }

        }


        // Name server resource records

        Record[] dns_nameserver_rr_array =
dns_msg.getSectionArray(Section.AUTHORITY);
        if (dns_nameserver_rr_array.length == 0) {
            // do something.
        } else {
            // do something...maybe print to verify
            int i = 0;
            while(i < dns_nameserver_rr_array.length) {

                System.out.println("Authority Record: " +
dns_nameserver_rr.rdataToString());
                i++;
            }

        }


        // Additional records section
        // Note: There will be ARCOUNT number of resource records in the
additional
        // records section.

        Record[] dns_additional_record_array =
dns_msg.getSectionArray(Section.ADDITIONAL);
        if (dns_additional_record_array.length == 0) {
            // do something.
        } else {
            // do something...maybe print to verify
            int i = 0;
            while(i < dns_additional_record_array.length) {
                Record dns_additional_rec = dns_additional_record_array[i];
                System.out.println("Additional Record: " +
dns_additional_rec.rdataToString());
                i++;
            }

        }



I have seen the RRSet and it has a nice iterator also. But, I think, a
simple record array is enough for me.
If there is a nice example that shows how to parse a DNS packet completely,
it would be useful.

Suggestions on improvements are greatly appreciated.


Thanks,

Message.numBytes() does return the size of the entire message; the provided "dig" helper program calls Message.toString(), which calls Message.numBytes(), and returns the full message size correctly.

The code looks correct, so I suspect that there's a problem with the data you're parsing.  The Message(byte []) constructor doesn't verify that the entire byte array was consumed by the parsing, so it probably wasn't.

Brian

[Periya.Data <per...@gm...>]

Right. I did a print of dns_hdr.toString(). All the 4 sections are 0. Hence,
getQuestion, as you pointed out, returns null.

       byte[] dns_msg_buf= new byte[2048];
        bb.get(dns_msg_buf, 71, caplen);
        Message dns_msg = new Message(dns_msg_buf);
        System.out.println("Message size: " + dns_msg.numBytes());
        Header dns_hdr = dns_msg.getHeader();

As I said before, there's a problem with your data.  If you're parsing a message, and the DNS header indicates that there are 0 records in all of the sections, the message parser won't try to parse any records, so Message.getQuestion() would return null.

Re: How to retrieve a dns message from a bytebuffer

Also, I get a null pointer exception error when I try to getName.

      // DNS Questions
        Name qname;
        int qtype;
        int qclass;

        Record question = dns_msg.getQuestion();

I am not what that means.  A valid record is not found? Is there a nice way
to check if a valid record has been returned? Maybe I am screwing up with
the starting of a valid DNS message from the bytebuffer.

Suggestions are welcome.

How to retrieve a dns message from a bytebuffer

[Periya.Data <per...@gm...>]

Hi,
    I have a bytebuffer of size 2048 bytes. Its initial bytes have some
custom data (upto 70th byte). From 71st byte, the DNS messages are there. I
think I know the length of the DNS message (I am not yet sure about this).

How do I get one message at a time from the bytebuffer?

 I am doing something like this:

        byte[] dns_msg_buf= new byte[1024];
        bb.get(dns_msg_buf, 71, caplen);   // bb is a byte buffer with
custom data and dns msgs. Caplen is the len.
        Message dns_msg = new Message(dns_msg_buf);
        System.out.println("Message size: " + dns_msg.numBytes());

dns_msg.numBytes => seems to be returning the size of the header only =
which is 12 bytes. Is there a way to find the total length of the message =
hdr + 4 message sections?

Thanks,
PD.

Hi Brian,

I reviewed the generated bundle ( generated via "ant bundle") and the 
contained OSGI Metadata. Everything looks fine, so no futher problems 
expected...

Thanks,

OK.  That patch was contributed, and I don't use OSGI.

Unless something comes up, within in the next week.  Are there any other potential problems related to OSGI that are going to come up in the future?

OSGI Metadata problem in dnsjava 2.1.1

[Norman M. <no...@ap...>]

Hi Bill,
I just noticed that you told others to use the mailinglist and not the 
forum so I repost it here ...

We (JAMES) are currently think about to allow our server modules to get 
deployed in an osgi container. We have one module (dnsservice) which 
depends on dnsjava 2.1.1 at the moment. I noticed while working on 
getting it run in the osgi container that dnsjava 2.1.1 has a junit 
package in its osgi imports. This is kind of a problem as junit itself 
does not export and package via osgi. We could repackage it but it kind 
of sucks ;)
This is fixed in current dnsjava trunk. so when using dnsjava trunk 
everything is working for us. But we cannot depend on unreleased code, 
so my question is:

When do you think 2.1.2 will get released ?

Thanks,
Norman

Re: SOARecord getSerial()

[Robert O. <un...@un...>]

Here's an example of how to get serial of the SOA record:

           SimpleResolver res = new SimpleResolver();
           Lookup lookup = new Lookup("google.com", Type.SOA);
           lookup.setResolver(res);
           Record records[] = lookup.run();

           if(records.length > 0 && records[0] instanceof SOARecord){

               System.out.println(((SOARecord)records[0]).getSerial());

           }else{

               System.out.println("Invalid response");
           }
