DOT Greyed out

  • DNS Benchmark v2 Release 5 with Consultant License
    Guest:
    If you own any earlier release of our DNS Benchmark you may immediately download its release #5 replacement. Running an earlier release will detect the new release and help you upgrade.

    Although this release is cosmetic, appearance matters and affects ease of use. The biggest change, as seen in the image above, is that the DNS Benchmark now has a traditional Windows application menu to more fully expose its many features. This release is also "Consultant License Aware" and GRC will now issue a Consultant version when owners have previously purchased four "Personal Use" licenses. If you have previously purchased four DNSB licenses, or if you wish to upgrade your "Personal Use" license to Consultant, GRC's purchase process will direct you through that process.

  • 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.

    (You may permanently close this reminder with the 'X' in the upper right.)

If you click the red icon in the UL corner of DNSB's main window, and get the main drop down menu, what do you see for the DOT protocol? Enabled or disabled? If it is not enabled then DNSB wile not benchmark DOT resolvers.

Sorry for the delay.

Yes I checked in the system menu and enable DoT tests is enabled, but every DoT server is red after the inital startup checks, this is with both with the NextDNS service enabled or disabled. It is as if discussed further up, either the compatibility layer can't operate with DoT or Ubuntu can't. I have checked and Ubuntu does support it if setup in the resolv file, but that is just for the DNS settings you are using. It needs to be available system wide and maybe it is not.

Gemini seems to suggest I can force NextDNS to use DoT instead of DoH if I want to, but, I don't think this will help this particular issue, as again, it will just be my localhost service using DoT.

I don't think DNS over TLS is actually a well used protocol. DNS over HTTPS came along after, and seems to have the lions share of the "secure DNS" mind share. Part of the issue is probably what you're running into... there appear to be so many different implementations of TLS in different levels of support on different versions of Windows (and Windows emulation like WINE and Proton) that it makes it hard to ensure the necessary functionality is going to be present. I get where you might want to see this capability working in DNSB, but I would recommend against spending much time trying to make it work when it's probably not going to reward you with results to care about.

DoH is fine for me, I just would like to see the full suite of tests running on Linux, I'm still not sure if anyone has so far.

Compare to one of my recent DNSBench 2 tests under Windows 7:

Messy, but I suppose this is what you are looking for.

I updated to wine 11, per the earlier suggestion, and now see why I suspect TLS isn't working

Code: 
0548:fixme:winhttp:netconn_secure_connect SECBUFFER_EXTRA not supported
GnuTLS error: Decryption has failed.
0548:err:secur32:schan_DecryptMessage Returning 80090304
0580:fixme:secur32:get_cipher_algid unknown algorithm 23
0580:fixme:secur32:get_mac_algid unknown algorithm 200, cipher 23

There are a couple of other errors, but it seems like Wine is missing some features to support winhttp/schannel
