Probably due to using systemd-timesyncd which I've never seen actuall
working. Install the ntp service and it will work.

It's one of the many parts of Bookworm I've had to junk and restore the

timesyncd works fine. Make sure that the route to the internet isn't
blocked. Use the command timedatectl show-timesync --all to see where timesyncd is looking for time. You can always specify NTP servers in /etc/systemd/timesyncd.conf. Use timedatectl status to see what it is
doing.

Raspberry has no RTC chip, so it will lose time when
powered off.

If there is a decent NTP server in the network the Pi
is connected to, it will synchronize to the server.

The undesirable characteristic of systemd-timesyncd
is that it is not willing to pass the time to the local
network.

Just install the ntpsec package and let it take care of
the time. There is a top -type utility ntpmon included.

I don't think your poblem is with systemd-timesyncd, it's with the

I'd tend to agree with Chris Green - it's a network problem. What's the default route? Do you have >1 network on the box?

The clock will stay "correct" without time syncronisation for some time.
One thing I do with every new box is run 'fake-hwclock save' every
minute (root crontab) so a reboot gets the nearly correct time immediately.

Of course the route to the internet isn't blocked, ntp and everything
else works fine.

Even if systemd-timesyncd did work there is no good reason to hand over
even more control of the machine to the insidious expanding mess of
systemd. There are alternatives which do one thing and one thing well,
systemd should just stick to being an init system.

The only way systemd will work properly is when the last vestiges of
Linux have been replaced and you boot straight in to SystemD OS.

The best thing to do you don't want to use an alternative init system,
is just use systemd *just* as init system, and turn off all of it's

In my deliberately limited experience building software with CMake,
much of the trouble is that program developers are expected to
write detailed documentation for the build options they use, but
for the software I've compiled they simply haven't. You've got a
wall of options, and usually nothing short of reading source code
to decide what they do and which are important to you. Then it's
more awkward (than with a configure script) to reproduce those
settings if you want to compile a later version the same way.

Its the usual mess of network manager/systemd all fighting to control something probably.

Yesterday I was getting connection refused on port 53, using the pi's

I added a working server on the network, and it sprang to life but when

I installed BIND which normally works out of the box.

I'm curious why you did that and why you didn't mention it in your
first post?

I had no idea thåt there was a DNS issue. I haven't modified BINDS
configuration, but now its *working*.

???

So I'm still curious, why did you install bind?

I wanted a proper caching DNS server on my home network. One that I
could use to put local machines on. This PI is to be the house server. Storage. Media. DNS. TV.

I've always used bind to do that. Usually it just works.

Yes, I do similar, but with dnsmasq. It used to be on my
desktop/server (permanently on because it's my mail server too) but I
have now moved it to a recently acquired Asus DSL router that runs asuswrt-merlin software.
