Correct. Unbound needs to be the primary handler of DNS requests to know who is asking. So dnsmasq disable is needed.
OR you could look at the dnsmasq logs.

no issues at all now that i understand how it works !! I probably wasnt making the changes stick by not running adblock after making changes in allowhost and blockhost. All i was doing was running rl. And i was making changes to thos files using Winscp - not the inbuilt Nano. Perhaps if you use those inbuilt utilities then gen_adblock.sh gets invoked after making changes?

Possibly...or I shot myself in the foot again
i.e. For me, normally for both Github cURL requests to complete takes a total of 1 second:
Code:
+ date +%s
+ local START_TIME=1590447645
+ curl -fLN --retry 3 --connect-timeout 3 https://raw.githubusercontent.com/MartineauUK/unbound-Asuswrt-Merlin/master/unbound_manager.sh

So now when things go wrong......it waits 10-12 seconds for just the first one (no point in trying the second) of the cURL request pair to fail:

Indeed as I proposed.
i.e. Options to manage the Whitelist/Blacklist are described under the 'Tools Advanced' menu
Code:
ew = Edit Ad Block Whitelist (eb=Blacklist; eca=Config-AllowSites; ecb=Config-BlockSites; el {Ad Block file})
Code:
e = Exit Script [?]
A:Option ==> ew
Ad Block file '/opt/share/unbound/configs/allowhost' changed....updating Ad Block

<snip>However, If you choose to edit the files manually say using WinSCP/Notepad++ (nano can be frustrating), then rather than wait for the daily cron job update,you can issue
Code:

A:Option ==> adblock updateI’ve seen that this is an experimental feature - making Unbound the primary DNS server, but what are the pros and cons of enabling this feature?
Whilst searching through this topic for answers, one con seems to be that Diversion would no longer work; is that right?

While I may be wrong and if I am hopefully someone will correct me....The main pro would be that all my searches aren't going thru big corporations who mine data (looking at you google
). Also since the lookups are cached on the router a response should be returned faster as it doesn't have to keep going out for the same query.As for diversion I still use Diversion and have noticed no issue running it. Have contemplated turning it off and using the adblock and youtube block exclusively from unbound manager but I feel like i'm cheating on Diversion a little as it has sufficed for so long.

The disadvantage that dnsmasq has, is that it can't do its own recursive dns queries and has to forward them to a resolver that can........ enter unbound..... instead of dnsmasq forwarding your queries to your ISP DNS, or Google, or Cloudflare ... or wherever.... dnsmasq will forward the query instead to unbound, and then unbound will directly query the root servers for an answer.While I may be wrong and if I am hopefully someone will correct me....The main pro would be that all my searches aren't going thru big corporations who mine data (looking at you google
As for diversion I still use Diversion and have noticed no issue running it. Have contemplated turning it off and using the adblock and youtube block exclusively from unbound manager but I feel like i'm cheating on Diversion a little as it has sufficed for so long.
So the experimental feature lets clients query unbound directly rather than having dnsmasq forward the DNS query to unbound.
The downside is that anything that relies on dnsmasq like Diversion wont work anymore.
I would say that for the "average" user (whoever that may be), running unbound behind dnsmasq is the preferred option, as stuff like unbound X3M routing etc will all continue to work.
The pro of running unbound as primary DNS is that you can be sure that dnsmasq is no longer in the picture, and you can experiment with unbound's features without worrying that the dns requests from clients have been tampered with (e.g using @juched ed ADBlock script to do ad blocking without having dnsmasq through Diversion intercept and block the ad domain first)

There is not real advantage of disabling dnsmasq. The amount of time that dnsmasq forwards request to Unbound locally is so small that is negligible. Second, Asus router firmware is build around dnsmasq and making these changes (disabling dnsmasq) is or will have a potential for issues down the road. Having both is the best you can do and Unbound is still your DNS server.
The issues one may encounter later plus the Unbound maintenance of the fast growing code base is not worth in my opinion to justify disabling dnsmasq. When you configure dnsmasq cache=0 and forward the dns queries to Unbound is good enough and in honesty you will not get any benefits from disabling dnsmasq - performance or otherwise.
how to disable dnsmasq cache? just add "cache=0" in dnsmasq.conf?
thx

you can't change the dnsmasq.conf file directly... you can do it using a dnsmasq postconf file but the unbound manager script does that for you. Check /etc/dnsmasq.conf
Code:
cache-size=0

So you are running with Unbound as your primary DNS server (dnsmasq disabled) and yet Diversion still works for you? (cf what Tomsk wrote: “The downside is that anything that relies on dnsmasq likeDiversion wont work anymore.”)

Sadly I would have to disagree...with your 'otherwise' statement.
There is a URL that tabulates (with caveats) the feature list between dnsmasq and unbound, and unsurprisingly they are for all intents and purposes identical....except
i.e. there is only one feature in the comparison table where unbound seemingly has a unique-selling-point:
Split horizon:
Servers with the split-horizon DNS feature can give different answers depending on the source IP address of the query.
Servers with the split-horizon DNS feature can give different answers depending on the source IP address of the query.
Now does this feature matter on a router, or more importantly, is this something that would be useful if applied to your home LAN devices?
Disabling dnsmasq would therefore open up the opportunity to exploit this currently unique unbound feature; ultimately experiencing the tangible benefit - wouldn't you agree?
P.S. You can review the DNS Server comparison here

I am checking the unbound behavior with TLS servers on port 443, forcing TCP.
Whoever has some knowledge, can test. One of the servers runs the knot-resolver.

The ideal is to use a comparator resource. Downloading when there is new root.hint. I will check your curl has this feature.

is servers-file=/tmp/resolv.dnsmasq the only line in your dnsmasq.conf?
is this already available with the current version of unbound_manager?
as in, can i disable queries for youtube for just one client (with dnsmasq disabled)?
thanks

thats weird... i think unbound isn't starting because it is expecting to listen on port 53535 but for that to happen the dnsmasq.conf should have a server=127.0.0.1#53535 line in it.
