Good catch Mr. dave14305. Do you also recommend adding the port after the interface ip's?
No not anymore really. It was an easy way to configure one interface with a non-standard port, but once you start actually using the port: parameter, the @ port method can just cause confusion.

Copy that thanks for clarifying this.
Can someone verify with unbound -V and see which version of openssl their unbound is running with. Mine shows OpenSSL 1.1.1d 10 Sep 2019.

when i switched to unbound only, i see that the websites are not automatically switching to their https versions.
i mean previously i wrote in ffox URL line only snbforums.com and it loaded page automatically with https prefix.
same happens when i open this URL from results of a google search - it throws an error about broken protocol :
Code:
Oops.

The site at http://www.snbforums.com/ has experienced a network protocol violation that cannot be repaired.

The page you are trying to view cannot be shown because an error in the data transmission was detected.

    Please contact the website owners to inform them of this problem.
now i need to add this prefix manually because it is trying to load HTTP.

have others same experience?

edit: page http://forums.mozillazine.org/ is not working even with https.
edit2: same behaviour in ms edge
edit3: update for antivirus is not working too as example. i see that it is resolving update servers dns but download is not working. same for WGC game center update.

Yes i understand, i wasn't meaning that they can't co exist. I was thinking more about the wasted memory.
If you are giving dnsmasq "first refusal" then what ever blocking list you have in memory for enabled unbound ad blocking would be duplication of effort (most likely using a very similar list of domains) just catching the dribble of domains missed by diversion. Similarly once you bypassed dnsmasq and did the ad blocking via unbound, the hostfile for dnsmasq would still be sitting in memory with no purpose.
I'm impressed by @Martineau efforts to enable flipping between the two with a simple command and just offered up the idea as icing on the cake, as he says, probably a niche use case, and maybe not worth the coding effort for the few that might want it.
Im pretty interested in the DNS firewall and see that as a potential complimentary feature to ad blocking through dnsmasq or though unbound which ever is active.
I've uploaded v3.10 Hotfix


Version=3.10
Github md5=6126e734d0ea5c65965cbae5a221f322

Use of the 'i = Update unbound Installation' **Not required** see Change Log

Code:
Hotfix: 'dnsmasq disable' (aka bypass dnsmasq) no longer listens on ALL interfaces, but only to local LAN subnet. - Thanks @dave14305
HotFix: Issue warning if bypass dnsmasq is requested and Router's Domain name is 'blank' before creating 'unbound.conf.localhosts' - @dave14305/@milan
Hotfix: Pending 'unbound.conf' v1.10,dynamically fix incorrect CIDRs (192.168.0.0/24->16 & 172.16.0.0/16->12) @dave14305 
Change: As per @Tomsk request, if Diversion is ACTIVE, when requesting dnsmasq bypass allow (semi-auto) replacing Diversion with Ad Block.
        Similarly if switching back to dnsmasq, allow (semi-auto) replacing Ad Block with Diversion
Change: Timestamp console messages when switching between dnsmasq or unbound as primary DNS
Code:
e  = Exit Script [?]

A:Option ==> dnsmasq disable

 If you currently use or rely on dnsmasq features such as Diversion/x3mRouting etc., then re-consider.

Hi Martineau..... the switchover for me still fails with unbound not starting because it believes there's still something listening on the port. I tried with DNS privacy disabled but its still failing..... i remember during one hot fix you removed a delay... does that need to be reintroduced? Any testing or logs you need i will be glad to provide.
Just for your info i rebooted the router just in case it a had got itself into a weird place... but still no help.... sorry this is proving to be a hard one to resolve... no pun intended.

The Hotfix means unbound no longer listens on ALL/ANY, so will now ONLY listen on a specific LAN socket (well two actually) so there is no need for a sleep delay.

So when 'dnsmasq disable' is used and unbound fails to start, what does the following show
Code:
grep -E -m 1 -A 5 "^port:" /opt/var/lib/unbound/unbound.conf
Is unbound still failing with the message '0.0.0.0 53' ?

EDIT: Corrected command typo :rolleyes:

the config looks correct... so there wont be a need for any delay to make sure dnsmasq has stopped listening?
Theres a chance that the previous hotfix didn't work with the DNS privacy off but i never tested that (apologies) as you requested i try with DNS privacy back on.....

im guessing its not there in the dnsmasq conf as that would have been altered back when dnsmasq restarted? ... does dnsmasq need time to restart with the port=0 config before unbound starts, as dnsmasq itself can't be stopped as the watchdog will restart it

Well because I'm stupid :oops:........I have uploaded a Hotfix.....

i.e. I am conscious of the 'assistance' of the watchdog, and I implemented this patch

/opt/etc/init.d/S61unbound
Code:
[ -z "$(grep "^port 53535" /opt/var/lib/unbound/unbound.conf)" ] && service restart_dnsmasq
which clearly you don't have (yet!) but I do :rolleyes:

Yep that's fixed it! :cool: Very nice... installed the adblock for me and disabled Diversion. i didn't try my luck yet with DNS privacy enabled but will let you know how it pans out

i tried a few dnsmasq disable/enable cycles with the DNS privacy on... no hiccups thus far
 
seems one restart fixed all my previous issues with unbound as main DNS.
now even cache hits are on 70 % and more.
i am really satisfied now with unbound, thanks all.
 
Dnsmasq disable definitely fixed unbound not working. It actually hit 80%n of the dns traffic. I removed Diversion, keeping Skynet only. My question is what unbound do with the dns address in the wan page, where I can't select the automatic setting.

With Unbound you are your own DNS server ..... if you do a DNS leak test you should get your own IP address.
Unbound will directly contact the root and top level servers instead of querying the server you enter into the wan dns box

I don't understand this statement :confused::confused:

unbound+dnsmasq combination is proven to be very stable and reliable. Can you explain why you say 'dnsmasq disable' fixed a non-working unbound?

NOTE: Whilst using unbound as the primary DNS server for your LAN (bypassing dnsmasq) does work, it is still an experimental feature. Use at your own risk
 
Experimental feature if people want to try. Based on a link posted in the diversion thread, there seems to be some new ways to make YouTube ads blocking (or at least greatly reduce).

https://discourse.pi-hole.net/t/youtube-script-seems-to-be-working-very-well/31316/68

Now, I am a YT Premium subscriber, so I don't see ads, but did some testing in an incognito browser, and it seems to be working.

So, I created a new script for unbound in my dev branch. You need to download it and place it next to the gen_adblock.sh file in /opt/var/lib/unbound/adblock/
Code:
https://raw.githubusercontent.com/juched78/Unbound-Asuswrt-Merlin/develop/adblock/gen_ytadblock.sh

Then add a cron job to run every 5 minutes:
Code:
cru a ytadblock "*/5 * * * * /opt/var/lib/unbound/adblock/gen_ytadblock.sh"

What this script does it check the unbound cache for hits to the googlevideo URL as indicated in the discourse thread above. When it finds hits it add them in as local-data items into unbound every 5 minutes.

Unlike the thread above, you don't need to find the IP to use, this script will find the first IP and use it, and store it for future use. So, you simply set it and start watching YT. after 5 minutes, and every 5 minutes it will check and expand the list, and soon your ads should start stopping or greatly reducing.

If people want to try it and let me know the results, that would be great. running the script directly will simply update the list and tell you how many YT domains are being redirected.

Thanks!

Note: This script doesn't restart unbound, and don't change any settings. To uninstall simply:
Code:
rm -rf /opt/share/unbound/configs/ipytforce
rm -rf /opt/var/lib/unbound/adblock/gen_ytadblock.sh
rm -rf /opt/var/lib/unbound/adblock/ytadblock

unbound_manager restart
