I have just installed Debian Bookworm on my backup server which is a
Fujitsu Esprimo Q556 with an 8TB external USB drive for backup. I was
previously running xubuntu there.
It has all gone very straightforwrdly, the actual installation only
took half an hour or so and configuring things not much more. I've
already run a backup from one of my smaller systems and it ran fine.
On xubuntu I have made a habit of removing systemd-resolved.service
and installing dnsmasq. (I know they're not quite the same thing, but
the result works OK)
Thus dnsmasq provides a local caching DNS service and it passes DNS
queries that it can't answer on to my main LAN DNS server. It uses
the file /run/NetworkManager/no-stub-resolv.conf to tell it where
the upstream DNS server is.
However my backup system is headless so doesn't have Network Manager
installed. (No desktop installed, just basic utilities and ssh)
It doesn't appear to have systemd-resolved.service installed either.
It works fine though. The /etc/resolv.conf is:-
domain zbmc.eu
search zbmc.eu
nameserver 192.168.1.1
which simply means all DNS gets passed to my LAN's DNS server. Is that
what one gets on a minimal installation, no explicit DNS server or
resolv management? I'm very happy with this, it's very simple and the
backup system isn't going to make a lot of DNS queries such that it
needs a DNS cache. Have I understood this OK?
