Am I the only one who cannot access www.ietf.org since Cloudflare enabled DNSSEC? (with dnsmasq-full 2.73-3)

Thanks.

I have trouble accessing ietf.org, also, with older versions of
dnsmasq + dnssec, presently.

Dave,

Sorry to be pedantic, but did you mean:

A) You did have the issue with older versions, and you still see that issue
with those old versions.

B) You did have the issue with older versions, and you also have it with
the current beta version of dnsmasq.

Thanks.

P.S. I'd had several weeks of issues with DNSsec enabled (due to the Google
issue), and disabled it about a week or two ago.

Dave, any chance to get a build of 2.73rc3?

So I suppose that means that Cerowrt is now unmaintained and that I should switch to something else, because my job requires near constant access to www.ietf.org and I will not disable DNSSEC.

So, what would you recommend for my WNDR3800?

Thanks.

Openwrt chaos calmer trunk (latest) as of a day ago has dnsmasq 2.73rc4
with suitable handling for DNSSEC.   Certainly I've DNSSEC enabled and
can browse the site you mention without obvious problem.

The automatic determination of 'valid current time' and hence checking
signature timestamps has an issue:  The startup script uses 'touch -t
1970epoch timestampfile' to pre-create a timestamp file which slightly
defeats the inbuilt dnsmasq logic...not helped by the fact '-t' is an
invalid option.

I stand corrected.

I still would really like people to pound dnsmasq flat with
namebench or other dns stress tests (anyone know of any? dig in a loop
would also help), using a native ipv6 dns server upstream. It used to
take days to trigger the bug. It may only happen on networks that have
issues with edns0.

Well, it was a more elegant solution that dnsmasq ultimately came up
with than what was in cerowrt, and I figure that single character fix
is a single bug report to openwrt and patch away... if someone else
not getting on a plane makes it.

I shall log a ticket within 48 hours, (if it doesn't get spotted and
squashed by someone else)  It's not just a case of not using '-t' but
rather of not trying to defeat the internal dnsmasq logic whilst fitting
in with the requirement of being able to create a file as 'nobody' in a
directory with a) suitable permissions and b) survives reboots, and
dealing with the new secure computing changes related to procd walled
gardens.  There are a few things pulling in opposite directions most of
which I've no clue :-)

I confirm that with openwrt trunk, I am now able to securely resolve www.ietf.org.

Yes, as funding for cerowrt has never arrived, there seems to be no
point in continuing. I put in several grant requests, none came
through, 1, is still pending, but it is very small.

I do not regard the loss of dnssec capability as worthy of updating
the 3.10.50 release, particularly when it is due to a misconfiguration
at cloudflare that they have not fixed either.

>that I should switch to something else, because my job requires near constant access to www.ietf.org and I will not disable DNSSEC.

Well it (also and ) more means that this fix to dnssec in dnsmasq are
part of dnsmasq 2.73 rc3 and later, which is not in any OS that I know
of at the moment, backports or not. There were also many, many other
fixes to dnsmasq in rc3.

There are other possible problems in dnsmasq, the most important being
a longstanding infinite loop bug that may or may not be fixed. I had
spun up 6 servers in the cloud to extensively test ipv6 and dnsmasq
and dnssec and edns0 etc - but did not find sufficient time to tackle
the problem myself and am leaving for vacation today.

If anyone here wants to configure namebench to go through the alexa
top 1million over and over again, using ipv6 primarily, and do other
stress test benchmarks like that against r2.73c3 and later - send me
your ssh keys - or please spin up your own servers in a cloud with
ipv6 in it (like linode), and/or dogfood elsewhere.

> So, what would you recommend for my WNDR3800?

Openwrt chaos calmer. Still won't solve your problem til someone gets
around to testing the patches and pushing them into openwrt.

I am taking my guitar and going off to this:

http://en.wikipedia.org/wiki/SpaceX_CRS-6

My backup plan, in case the internet failed, was always to get off planet.

I am quite fond of the Arkyd-3.
