It seems when I use 192.168.1.1, thus Stubby, as my DNS resolver. It seems that sometimes a page can't be found/domain name not found, then if I refresh the page a couple of times... it suddenly can find it again.


This doesn't happen when I set the WAN DNS to 1.1.1.1 directly, so it's not Cloudflare.

Anyone experiencing the same thing?

Yes. But not when using Cloudflare. With DNSSEC enabled and resolvers set to Quad9 or Cleanbrowsing Secure after a day or so of successful operation I suddenly can't resolve addresses. Yesterday I was using DNSSEC in dnsmasq and logged an error "Insecure DS reply recieved...."

Working Now. If i have missed anything or it looks wrong just let me know thank you all for the help

Looks like this was the problem

Your script need a fix.

Entware version has newer release number 1.4.2-2 on the other hand patched version is 1.4.2-1a.

Cool!

I would like to do something similar for unbound (with openssl 1.1.1a statically), for AC86U and AC68U.

Where can I find how to do this? Do you have any pointers?

Same here: I have for Quad9 and Cloudfare setup the Primary/Secondary servers - totally 4 - in round robin mode - normally it works fine, but I also experienced the not found problem (with reload it works).

My interpretation was the heavy load on my router with Deluge (Torrent-Client) - but it could be a different issue... :rolleyes:

Update: While checking the setup via Cloudflare "Browsing Experience Security Check" I saw mixed results for the Secure DNS status. Removing Quad9 from the configuration showed good results - even when refreshing the test multiple times - so Quad9 seems to be the culprit of my issue...

There are new options available in stubby 0.2.4.
Code: 
tls_ciphersuites (for TLS >= 1.3)
tls_cipher_list (for TLS < 1.3)
tls_min_version
tls_max_version
I personally added two options in stubby.yml.
Code: 
tls_min_version: GETDNS_TLS1_3
tls_ciphersuites: "TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256"

Default cipher suites priority is
Code: 
TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
HND routers can accelerate SHA1 SHA256 but not SHA384.
I think this is not a big factor, anyway it gives me better feeling :D

You can add the RT-AC5300 to your list, I am passing all the tests for "validating-that-stubby-is-working" on the project page.

I am still reading over some of the topic, so I’ll hold a few questions that I have for a bit longer.
 
Hi,

Please, one question I have: is possible to block adds using Stubby?

Thanks!

Err, no. That's what the likes of Diversion and Skynet are for. Stubby only changes the transport method in which queries are made to DNS servers.
 
I've installed this months ago as instructed in OP.
I have been reading in this thread about updates and other forks, will the OP get updated to show how to update to latest version?
Thanks for info.

Thanks Jack. I was just re-installing and noticed the install command on github points to https://raw.githubusercontent.com/Xentrk, I think it's probably always been like that, as I seem to remember manually changing it to https://raw.githubusercontent.com/jackyaz previously, or maybe it was correct before but changed back at some point. There's probably a post here in the thread with the correct command, but I had your github page bookmarked and copied & pasted the command line without noticing or remembering it needed changing. And then of course it installed the normal getdns and I had no internet until I reset my WAN DNS and started again.

Thought I'd mention it in case it's easy to change and you have time. Big thanks to @Odkrys for the patched versions and yourself for the forked installer.

Edit: While I'm asking :)
Code: 
echo | openssl s_client -verify on -CApath /rom/etc/ssl/certs -connect 1.1.1.1:853
seems to need changing to
Code: 
echo | openssl s_client -verify on -CAfile /rom/etc/ssl/certs/ca-certificates.crt -connect 1.1.1.1:853
as well.

Ah, that's an oversight on my part. I'll get that fixed
 
Well, we had a huge power blip/surge, the worst one in the 20 years I have been in this house.

Luckily my 5300 seems to have survived, however I was unable to get back online. This necessitated a complete reset, it was quicker and easier than troubleshooting with a wife and kids breathing down my neck. All kinds of issues, no problem with the selective restore. I had great backup's of my prized static IP address list :p

I did try a few steps like adding the command for the ntp to dnsmasq...add fearing it was that issue. However, that did not yield any successful results. So here goes round 2 :) from scratch.
