I can but considering how there was a post about how someone had to manually delete all files related to unbound I thought I’d ask. Guess you missed that post.
Thanks for the directions.

Probably not.
If you download 'unbound.conf' from GitHub using the '1/i Install/Update' then by default both are commented out.
If 'lo' is used, then the script should only auto-ENABLE the 'log-queries' - basically to prevent unmanaged native unbound logging from silently filling the disk.
(NOTE: With the new fail-safe cron job to restrict the native unbound log from growing larger than 10MB, perhaps this should now be changed.)
If you then enable 'scribe' or 'sgui' then both 'log-queries' and 'log-replies' should be auto-ENABLED.

No I can read...(and count) thank you, but if you are technically astute, then it's the OPs prerogative to choose whatever manual action is deemed appropriate in the circumstances....however, in the OP's particular case, it wasn't strictly necessary.
Sorry to see you go.

my normal scripting prowess.... fix something ... break something elseWhoops, looks like for the v3.06 rewrite - I've somehow dropped the line

Fortunately 'lo' should still dynamically ENABLE both, so issue 'lo' and that should fix it!
i.e. you will then see the 'log-replies' in syslog-ng but 'unbound.conf' will still show it as commented out, or you can 'vx' it
I'll add it to the pending v3.08 Hotfix.
When updated Unbound, it says my configuration contains duplicates. I am not really sure what to look for. Someone with ideas?

I sincerely appreciate all the effort you put into unbound manager and the time you take to the answer questions and issues posted in here. Unbound can be confusing to some of us and your script goes a long way to making it so much more manageable. I am always in awe of the skill of script writers such as yourself (and the rest in here), Lord knows I’ve learnt so much!!(and there is so much more to learn!!)

When looking at the error message, doesn’t it tell you which line is duplicated? I believe that was the case for me once.
Indeed it did. Thank you.
I now have other issues with libunbound. I will try things according to this before asking for further help. Really need the router to work since I am working from home due to Corona. I will try it this weekend.

But DNS is still resolving? The below answer should be no, else you are getting your isp's dns service. You are done with them you got your own DNS resolver now.

That is not correct at all - a successful installation of Unbound overrides this setting. When Unbound is stopped either accidentally or commanded then this setting will allow successful resolving to your ISP's DNS servers. The problem with MartinDEE is presumably tied to the fact that his NTP server is non functional and NTP is not synced. Fix that first before you look further.
Install NTPMerlin using amtm and hopefully that will fix your NTP issue.

I had noticed from a month or so back that the cache hit statistics were steadily declining over time [from high seventies where it had stayed consistently before ... to low sixties] – which did not make sense in a small household where the internet usage patterns are fairly consistent.
So - I setup a factory reset router with my usual amtm add-ons – all fresh installed on a formatted USB – and then monitored unbound cache stats with only a SINGLE client PC attached to the router by Ethernet cable. I went about opening the same web pages [30 of them] repeatedly but clearing the DNS cache on the PC between each of the attempts.
After an initial modest pickup in cache hits – I found that repeated opening of the same web pages caused the cache hit stats to DECLINE ??? See images below ...
This one shows summary stats after a few browser sessions ...
This one straight after above with a single push to open those same 30 web pages.
Note %tage decline on hits from 35.75 to 30.79 ??
Full graph chart enclosed below ...
Any one else noticing a similar trend ???

Won't the DNS caching on the requesting machine make the figures drop?
He said:
but a "PC" makes other DNS request in the background.

sgui just needs log-replies. No need to turn on log-queries for the stats, they are ignored and just fill up the disk.
