Upgrade right now? No.

If your configuration works and can be easily extended and you are
happy with it — use iptables.
If your configuration is generated by something — check the new

If your setup works fine, use apache2 as php runner.
Nginx needs config exercises for .htaccess replacements and this is
sometimes too complicated for beginners.
For performance on multiple slow clients add nginx as reverse proxy
(as most other hosting setups), or use apache proxy module (never seen
last ~15 years).

Nginx is faster than apache2 because it get all data from backend,
send it to a slow client and backend ready to new request while nginx
sending data.
Apache2 can do it with proxy module, but i was see such configuration
around 2006, nginx as reverse proxy easier to configure.

I run qemu binary with parameters and place disk image in any place
and can use any physical disk as qemu image, if need.
In old scripts it was something like:

qemu-system-x86_64 -m 1024M -hda /path/disk.img -cdrom
/another/path/image.iso -boot cdrom

So, it is not qemu, only your gui wrapper/interface limitation.

this is not qemu/kvm thing, only libvirt, which is not part of qemu,
but only wrapper on it. Sometimes useful, good for beginning, bad, if
you need something non-standard.

qemu as virtual machine does not create/use firewall rules at all and
can use user mode net, which work without firewall rules — see man
qemu for -net parameter (use -net nic -net user if you need only
output network requests).

If your hardware supports 6 hard drives (5*18T + your 2T), you can use
lvm for merging 5 of them to one volume, or create raid0 by mdadm.
Some risks with plain disk merging - if one of your drives die, entire

I don't use libvirt/virtmanager (hosting control panel was written

How you plan run your app?
Important questions for choice:
Do your app use .htaccess/.htpasswd and .ht* must be reconfigured in
runtime by user?
Do your app use cgi or mod_php and can't be run as fastcgi/fpm/wsgi?

If any answer 'yes' or 'don't know' - apache.
Or better nginx as reverse proxy in front of apache as application server.

nginx may replace apache, but their configs have no user access and
another format + it's not an application server, their capabilities -
to proxy requests to another app and serve static files.

yes, but how about something like python's pep8/flake8 or any other

Sometimes more than one way will be disadvantage.

For short, simple and selfdocumented scripts using perl is a best way,
but for something more complicated... Only if can't use something
other.

Also I will not recommend perl as first language. Only after python
and C (or any other low level compiling lang).

I know. Mitigate it by installing all to wooden board and don't use

Orange Pi 3 LTS does not have another interfaces for really big
non-network drives, only one usb3.0 (up to 100-110MB/s on my hdd
drives, does not test on ssd) and two usb2.0 (up to 30MB/s)

Yes, but for home use one hdd in usb3.0 is enough. I have no cables to
my notebooks, only single wifi point, so 1Gbit of storage connection
and 100MB/s of primary hdd does not main speed limiting factor.
It was very budget solution and will work until replaced to more
reliable but more expensive one. Or not replaced -- it's work and data
somtimes duplicates to another place.

All is ok, but you miss some info: "even on Orange Pi". Even.
It's worst case for OpenMediaVault. On normal PC with intel/amd
processor it work better.

You can try x2go as opensource child of nomachine, if DE in
compatibility list (https://wiki.x2go.org/doku.php/doc:de-compat)
Work over ssh, can and do screen compression, forward sound (was try
only in browser), printers (from local to remote) and partially
clipboard (may be not partially, my instance outdated).
May use LAN with excellent image quality and edge modem with very low
bandwidth with low fps and jpeg aliases on image.
I'm use it on remote desktop server, so have no info on connecting to
normal session, but theirs wiki contain page
https://wiki.x2go.org/doku.php/doc:usage:desktop-sharing

Some colleagues use SPICE protocol, but i have no experience with it.

Me used that some years ago - 4GB ram was accessible only with 64bit

Re: is it possible to install bullseye by copy whole disk?

yes, i do this:
1) make neccessary partitions  and fs and mount them -- man parted,
man mkfs, may be man pvcreate, man vgcreate, man lvcreate, man mount)
2) copy files with xattrs, selabels, capabilities to new place (/boot
to new boot partition, / to new root partition, etc) -- man cp or man
rsync
3) change fstab on new system -- man vi or man nano
4) mount / and after that /boot (if exists) into /mnt and /mnt/boot respectively
5) mount --bind /dev /mnt/dev; mount --bind /sys /mnt/sys; mount
--bind /proc /mnt/proc
6) grub-install /dev/disk # /dev/disk is a device with new /boot part
7) umount all from /mnt

About 15 years ago similar process was used to deploy several hundreds
of new workstations from prepared tar of master image - simply boot
from livecd and unpack system to prepared mountpoint.

If you ask such questions - get some practice on virtual machine
before install on real computer.

Years ago in 2009 with users in LDAP (with pam_ldap) i use
pam_mkhomedir on debian and some russian rpm-based distro.
pam_mkhomedir will be work now as in 2009.

I think, most RH-only services must be used only if most of your
servers are RH-based and you vendor-locked on RH.
If datacenter not RH-based, then i prefer more universal solutions,
which work on RH too.

I think, you shoud look to /etc/pam.d
Not all configs work as expected, when need some strange (e.g. not
localhost desktop or alone server)

1) you may try backports, may be your software already backported and
available on debian 10. If software backported - quick and easy way.

2) you may backport software by self (get sources, sometimes fix
debian/* in sources dir, build package) -- my preffered way to take
new software before debian testing not frozen.

3) you may set repos from debian 11 and install software AND
dependencies - your debian will be partially upgraded and some another
soft may be broken. Don't recommend this way, system may be broken and
need reinstall in worst case.

4) you may upgrade to debian 11. If you does not see your software in
backports and can't build package - use this way.

You can see content of installed package by command:

dpkg -L mysql-connector-java

And i recommend you do not install packages by hand before searching in repo.
May be this package for you: https://packages.debian.org/buster/libmariadb-java

openssl in wheezy very outdated and was outdated even when wheezy was
been ELTS - when i work on hosting provider, i need to add some
ciphers to nginx config for talking with wheezy client in 2017.
Now wheezy abandoned and nobody will be port new ciphers to very
outdated openssl version.

If you want quick and working result, recommend you upgrade to
something new version with clean install - direct update to actual
version does not possible, step-by-step to current stable release with
4 steps may take you "frankendebian" result or you will need to
cleanup system from old packages after every step.
If you want experience with updating very outdated system to simply
outdated system - use archive.debian.org for 1st upgrade step.

My standard actions in such situations (unknown root password + no sudo rights):
A) boot from livecd, mount root partition into /mnt, chroot /mnt,
passwd, umount /mnt, reboot from hdd.
or
B) at boot add line to kernel parameters:
init=/bin/sh

after boot at prompt:

mount / -o remount,rw
passwd   # change root password
sync; sync
mount / -o remount,ro

and reboot (may be via reset button or power switch)

Either remount filesystems to rw, if you mount it in ro before run
apt, or reboot and repair filesystem.
Also this may be hardware problem with disks.

And please next time send diagnostic in english:
