This system has NO nameservers configured for its use.

  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Hi again,

I have run the benchmark twice using different settings and still get this error telling me I have no nameservers configured, although I do. I have no connectivity issues and the benchmark is running fine.

On the first run my laptop was setup to use DNS from my router, in this case a google wifi hub using cloudflare 1.1.1.3.

On my second run, the laptop was setup to use NextDNS via the localhost command line tool which they provide for Linux.

I do also get some errors in the terminal whilst the benchmark is running, but they don't appear to be a problem. I would guess it's just popping up errors for certain resolvers not playing ball.

The only unusual thing is that I'm running Wine on Ubuntu.

Hi @GreenWine:

DNSB obtains the list of locally configured resolvers from Windows (or WINE). What happens if you do this:
  1. Open the Add/Remove dialog.
  2. Remove All Nameservers.
  3. Add System's Nameservers.
This will clearly show you what the Windows API finds. If you do not see anything added when you "Add System's Nameservers" then DNSB is unable to pickup your machine's locally configured DNS resolvers so you'll need to add those yourself, manually.

Note that you can do this and make it automatic in the future by saving a "dnsbench.ini" (default name) file which will be seen and loaded whenever DNSB is started. (y)
 
... versus NOT being able to save System as INI otherwise.

Second thoughts on that?

Thanks.

DNSB's deliberate exclusion of a system's resolvers from its .INI files won't be a problem for @GreenWine since the reason he would be adding his system resolvers to a custom list is because they are not being automatically found and identified as system resolvers by DNSB. Thus it will not exclude them from the INI save. (y)

Hi Mr G.

I cleared the nameserver list and then pressed add system ns and nothing happens, the table remains empty. No error pops up on the terminal when I push the button either.

When I press add default ns, the tool gets busy again populating it all.

Now what I didn't notice before is that when I first launch the benchmark, I get this error back behind on the terminal. Maybe this will be why it's not finding my DNS NS?


0128:err:winediag:ntlm_check_version ntlm_auth was not found. Make sure that ntlm_auth >= 3.0.25 is in your path. Usually, you can find it in the winbind package of your distribution.
0128:err:ntlm:ntlm_LsaApInitializePackage no NTLM support, expect problems



Not a problem for me, happy to add my current DNS manually (and I did and got a rather interesting result which I may share on another thread if it keeps occuring - in short though, my nextDNS result was SO fast compared to the others, it looked freaking impossible - which makes me think every previous dns test query was cached locally)

Okay. That confirms that your WINE is not "seeing" your local resolvers. I'll ask over in the dev newsgroup whether this is true for everyone. Thanks!

I tried the tip from a listener to SN and tried using Steam to run the BM and it can see my local DNS servers, so in this aspect, an improvement over Wine.

Steam uses a fork of WINE called Proton. Its focus is for running Windows games on Linux. I think most of the extra stuff it has support for are things that might not matter to the likes of tools like this, but you never know.

Looks like Valve have taken Wine and used some of their infinite money to improve upon it.
 
That's basically it. Also, it helps they made a device that runs Linux but wanted their customers to be able to play as many games as possible on said device.

Because they're coming out with a device next year that runs on an ARM processor, they added running x86 apps on an ARM chip to Proton. I have seen talk about this support before they announced the device. Also, I'm not sure if a version of Proton has been released that allows normal people to test that bit yet.
