Apache2 on Debian 9 and 10 is started from systemd. it has
PrivateTmp=true
in its definition. So processes started from the server don't have access to the regular /tmp and /var/tmp directories. Instead, they have their own directories.
You can either move the socket out of /tmp or start apache2 with
PrivateTmp=false

FILE_NAME is being passed directly to bash -c in the -exec option of your find command. This causes problems if FILE_NAME contains quotes/shell code. In fact, arbitrary code could be executed. Example: in this particular case, the input file could contain a line '; echo "run commands";'
Instead, pass the loop var to bash -c as a positional parameter. e.g.:

I would write it like this.
#!/usr/bin/env bash
pattern_file="$1"
while IFS= read -r -d '' file; do
transmission-show "$file" | awk .... "$pattern_file" ##: Figure out how to do the awk with a file rather than looping through an array.
done < <(find . -maxdepth 2 -name '*.torrent' -type f -print0)
That should avoid the quoting hell :-)

I wouldn't trust the Hardware RAID. If that bios or motherboard ever failed, you're done. No recovery is possible. I would turn that off and go with a software type of RAID 10. That way you have a better chance of recovery from another source.

When your only connection to an X11 server is untrusted, you cannot forward it further.
The untrusted X11 forwarding works by the ssh client connecting to the local display, and using the xauth generate $DISPLAY . untrusted command to generate an untrusted key / cookie.
But for that, the xauth command needs the SECURITY extension to be present on the ...

How to manually partition your Debian install with full disk encryption
I am going to outline the steps to take using the netinstall ISO on Virtual Box. These steps should work the same as any of the full Desktop environment installers with Desktops. (Do note that near the end of the netinstall, you can choose a Desktop environment of your choice.)

Nautilus currently doesn't support shortcut's customization. There are many similar threads as this one with complaints about Nautilus' lack of shortcut customization and the old solutions available don't seem to work in 2020.

You can disable the plymouth-quit-wait.service to make the boot process more faster:

If you don't have some package managed by snap you can disable the snapd.service.

The /proc filesystem is simply a set of data exposed as files, so you can operate on them like you do any other file, with cat, grep, etc.
One example of a thing I do in my shell configuration is operate a little differently depending on the process that started my shell. So I can write something like this:

While it's not explictly written, I guess the goal is to split traffic such that:
172.16.0.0/24 traffic flows through enp1s0f1
10.0.0.0/24 traffic flows through enp4s0f0
As OP wrote, this needs policy/source-based routing. iptables and netfilter are rarely useful (at least alone):

I believe the 'Host Bridge' that lspci is referring to is the PCI host bridge that connects the CPU to the PCI bus. I have a 3rd generation Core i5 and my host bridge description says:

I also tried a lot to do this. Actually there is a term for this called "persistence". In my experience, it works only when I create the bootable usb drive with Rufus. In Rufus, when you are creating the bootable usb, there will be an option to set persistence and the size of the persistent partition. It will make the live boot slower but at least you will ...

Your file system is over 16 TiB in size, so mke2fs defaulted to the “huge” file system type, with an inode ratio of 65,536 bytes. See the -T option in the linked manpage, and the huge type in mke2fs.conf:
huge = {
inode_ratio = 65536

Assuming systemd you could create the two systemd units shown below, enable them with systemctl --user enable bt-agent-d.service; systemctl --user enable pulseaudio-d.service and finally enable lingering in order to start them at boot and not to stop them if the user logs out with loginctl enable-linger username.

apt-cache pkgnames is designed for use in tab-completion: it quickly generates a list of all the package names apt knows about for the system’s main architecture (whether installed, available remotely, or simply mentioned in some other package’s relationships).

Upon further investigation and discussion with Stephen Kitt I found that I had 2 different versions of virtualenv on my PC:

To avoid messing things up outside the virtualenvs, I recommend using the packaged versions:
sudo apt install python-pip virtualenv
(along with python3-pip for Python 3 support, if appropriate).
You’ll probably need to remove the versions of pip and virtualenv installed in your home directory, and any others on your PATH outside /usr/bin.

Is /sbin in your path? Run echo $PATH to check. Often /sbin is a symlink to /usr/bin so check if that is also in the path.

I´ve had same problem, which I solved:
Change group to user on rules.v4
sudo chgrp "usergroup" /etc/iptables/rules.v*
Enable writting permission to group
sudo chmod 664 /etc/iptables/rules.v*
Try again
sudo iptables-save > /etc/iptables/rules.v4
This worked for me, I hope it helps.

You should not need a FQDN; just use the host part. For instance:

Found it !
It seems that my router has a DNS server indeed :
nslookup host_ip router_ip
Server: 192.168.1.254
Address: 192.168.1.254#53
69.1.168.192.in-addr.arpa name = hostname.lan.
So that answers the .localvs .lanquestion. In recent Debian, the local domain is .lan.
Still, ping hostname.lan returns unknown host.
Thanks to https://askubuntu....

Naturally I don't know your exact setup, but I think two things are going on here. My setup is similar to yours in that I have a native (untagged) VLAN with subnet 192.168.1.0/24 and VLAN20 running on the same interface with subnet 192.168.2.0/24.

Searching nVidia, it seems version 435.21 is the minimum needed.
Those aren't debian offered versions of nvidia-driver packages, but buster-backports give you the opportunity to use 440.59 as of writing. You should add backports in your repositories and force nvidia-driver from there.

I had the same issue, basically UUID's got mixed up after disabling and deleting my swap inside a virtualbox. This caused timeout issues and dependency failures, and it forced a file system check on each boot. I had to update my UUIDs accordingly.

Welcome to Unix & Linux StackExchange!
You can get a full list of installed packages with e.g. dpkg --get-selections | less.

Also, with X11, it is perfectly possible to run a ...

I would have a look at the system services. It is a good idea to review the default setup, because there may be services that you don't need, and you can disable them to improve performance, even reduce the attack surface (for example there may be a webserver running, that you don't need).
To list all loaded services on your system, including failed ...

If your firewall uses the built-in kernel firewall, then sudo iptables -n -L will list all the iptables contents. If there is no firewall the output will be mostly empty.

Yes, you can clear apt’s index by deleting all the files in /var/lib/apt/lists:
sudo rm /var/lib/apt/lists/*_*
(all index files have underscores in their names, none of the directories in /var/lib/apt/lists do).
