Firefox and VM

[Steve B via PLUG-discuss]

I've been using Apparmor and Firejail to secure Firefox for the past few
years. However, for sometime now I'm finding that Firefox profiles for one
or the other do not appear to be maintained. Consequently I'm looking to
move my use of Firefox to a VM.

My dilemma is what OS to use for the VM. Alpine or Damn Small were my first
considerations. Small footprint, just the essentials and then add Firefox.

Is anyone here doing something similar? Looking for suggestions as to which
OS to use.

PXE boot server

[Steve B via PLUG-discuss]

Recently acquired a HP 800 mini that I have setup and am using as a PXE
boot server. At present I have Clonezilla and Parted Magic being served
out. What other tools are others using that might be useful for a SOHO
environment?

I'm planning to shutdown my Raspberry Pi and move AdGuard over as well as
installing Docker to run TrueCommand.

These are the tools I use the most, and since the HP opens other
possibilities thought I'd ask around for ideas.

PXE and PartedMagic

[Steve B via PLUG-discuss]

Trying to setup a PXE server in order to have some of my tools such as
CloneZilla and PartedMagic available rather than use a flash drive.
Client machine boots PXE and I am getting the PXE boot menu, but cannot get
PartedMagic to boot.

dnsmasq.conf looks like this:
port=0
interface=eth0
dhcp-range=192.168.1.0,proxy
enable-tftp
tftp-root=/mnt/data/netboot/boot
pxe-service=x86-64_EFI,"PXELINUX (EFI)",efi64/syslinux.efi
log-queries
log-facility=/var/log/dnsmasq.log

Parted Magic resides in tftp-root=/mnt/data/netboot/boot/pmagic

PXELinux default file is current configured as:
LABEL pmagic64
DEFAULT vesamenu.c32
MENU TITLE PXE Boot Menu
MENU LABEL Parted Magic 2019
LINUX pmagic/bzImage64
INITRD
pmagic/initrd.img,pmagic/fu.img,pmagic/m64.img,pmagic/files.cgz
APPEND edd=on vga=normal

Last entries from the log say:

I'm not understanding why the bzImage file is being looked for in
/mnt/data/netboot/efi64 and not /mnt/data/netboot/boot. Can anyone with PXE
knowledge five me some assistance?

Docker

[Steve B via PLUG-discuss]

I"m looking to dip my toes into Docker for use on my home network. Reading
up on what to consider for running atop the bare metal it seems like two of
the most mentioned have been discontinued - CoreOS and RancherOS, and
Atomic supposedly is not quite ready for production. At least according to
some articles.

What are others using to host their Docker containers on their home
networks?

Re: Anyone use Google Fi ??

I've been using it for a few years now and have been very happy with it.
Spam filtering on phone calls and text messages is superior to the VZW /

Re: Handbrake, Flatpak and Pop OS

[Steve B via PLUG-discuss]

I uninstalled the Flatpak version and installed an older Deb package and
now everything is working again.

Could it be that libdvdcss is not part of the Flatpak version, or that the
Flatpak technology is unable to access libdvdcss outside of it's sandbox?

Handbrake, Flatpak and Pop OS

[Steve B via PLUG-discuss]

Recently I reinstalled Handbrake to Linux (Pop OS) hoping to start ripping
DVDs again. Previously it was a deb package but it appears Handbrake has
moved to Flatpak for Linux distribution.

This version of Handbrake is not working for me and I'm struggling to
understand what I am doing wrong. When Handbrake scans the DVD it does not
find anything. I have to open and start the DVD in VLC and then Handbrake
it will find it in its scan. What it does find shows as pixelated in both
the preview as well as any rip it makes for me. I've tried a handful of the
presets and no matter what I chose I get the same pixelated output.

Are there any other Flatpak/Handbrake users in this group that have it
working successfully for them who can give me some guidance?

Pi-hole, Linux hosts file and local DNS

[Steve B via PLUG-discuss]

Is there a way to use Pi-holes local DNS functions to create entries for
services on my local LAN?

For example if Pi-Hole is at http://192.168.1.160/admin can i create
something that has that full URL? The Linux hosts file limits me to the IP
address and I'm looking for a way to have anything that comes after the IP
such as port numbers and such.

NFS/SMB and ransomware

[Steve B via PLUG-discuss]

Looking for some information regarding networked file systems and
ransomware. If my understanding is correct, should a PC get infected with
ransomware it can search out and encrypt NFS and SMB shares.

Would it be correct to assume that in order to encrypt an NFS or SMB share
they would have to be online? If the device on which the network file
system was located were powered off, could it be woken via a WOL command
and then encrypted?

I currently have a TrueNAS machine that houses all my media and is also my
Plex server. It also has an NFS share to which I backup as needed. In
addition I have a Synology NAS to which I have a backup copy of the TrueNAS
server.

Re: Editing firefox.desktop

[Steve B via PLUG-discuss]

Success -  I could not get any farther than what I posted the other day
using ~./local/share/applications/sandfox.desktop, but I achieved 100%
success by editing /usr/share/applications/firefox.desktop.

Under the main {Desktop Entry] I appended "sandbox" to the Actions
parameter and then created a new [Desktop Action sandbox] submenu with the
lines:
[Desktop Action sandbox]
Name=Open in a sandbox
Exec=firejail --apparmor --private --dns=89.233.43.71 --net=eno1
--netfilter=/etc/firejail/nolocal.net --seccomp firefox -no-remote

Now if I right click on Firefox I have "Open in a new window", "Open in a
new private window" and "Open in a sandbox". A quick "firejail --list"
confirms firefox is running with the full parameter string. Yes, I'll have
to add it every time Firefox updates, but for now I'm willing to live with
that. Gives me motivation to look into John's suggestion of learning to
patch the file.

Also found that my firejail-profile package was corrupted and that is why I
could not get --net= to work. Purged and reinstalled the package which
solved that problem.

Re: Editing firefox.desktop

I looked again and made more progress. Edited sandfox.desktop to read:

#!/usr/bin/env xdg-open
[Desktop Entry]
Type=Application
Name=Firefox (Sandboxed)
Exec=/bin/sh "/usr/bin/firejail --apparmor firefox"
Icon=/home/steve/Pictures/firejailed-firefox.png

I get a shell of an icon in the menu with the text below it. Still can't
start the browser, but more than I had yesterday.

Re: Editing firefox.desktop

[Steve B via PLUG-discuss]

Thank you. The original goal was to add it to the menu in Pop OS. I'll look
again, but don't recall seeing it after I created it in
~/.local/share/applications. Do I need to use "--register-app" to add it,
or should it just show up?

Re: Editing firefox.desktop

[Steve B via PLUG-discuss]

On a side note, could use a little help with the restricted network
function. Something changed between earlier versions and 0.9.64.4. In
earlier versions I could use "firejail --apparmor --net=eno1 firefox" to
create a new network stack. When I try to use it now I do not get any
errors, but am unable to browse to any site. If I change restricted-network
to yes I get the error "Error: networking feature is disabled in Firejail
configuration file". Networking is enabled according to both the config
file and to "firejail --version".

The developers notes in /etc/firejail/firejail.config say "Restricted
networking grants access to --interface, --net=ethXXX and # --netfilter
only to root user. Regular users are only allowed --net=none. I'm guessing
that firejail sees me as a regular user and not as a root user?

Re: Editing firefox.desktop

[Steve B via PLUG-discuss]

I took Brian's recommendation and created a file in
~/.local/share/applications called sandfox.desktop. Contents of that file
are:

[Desktop Entry]
Encoding=UTF-8
Type=Application
Icon=/home/steve/Pictures/firejailed_firefox128.png
Exec=/usr/bin/firejail --apparmor firefox
Name=Sandboxed Web Browser
Terminal=false

I have it set to executable but when i try to run it "./sandfox.desktop" I
get the error:
./sandfox.desktop: line 1: [Desktop: command not found
./sandfox.desktop: line 5: --apparmor: command not found
./sandfox.desktop: line 6: Web: command not found

Is my file misconfigured or what do I not have correct?

Replacement fan for a Pi 3b+ POE hat?

[Steve B via PLUG-discuss]

I've been running Pi-Hole on my 3b+ for a while now. She's POE powered or
was until recently. The POE hat still fires it up, but the little fan
mounted to the top acts somewhat dead. When you first connect the Ethernet
cable the fan briefly moves, but then nothing. Google did not appear to
find a replacement fan. Would anyone have a source for such a device?

Re: Radeon card recommendations

[Steve B via PLUG-discuss]

I've been digging through some of the Arch and Gentoo documentation trying
to get a handle on which of the older Radeon cards use the drivers built
into the kernel. While they do a good job about telling me chipsets and GCN
architecture, I'm still struggling to find a card.

The Optiplex 9020 I own uses a PCIe x16 slot, first generation or possible
second. I've been using the integrated Intel for now but would like to add
a discrete GPU. If I'm reading the Arch and Gentoo docs correctly most of
the cards seem to be more gaming oriented and require a connection to the
PSU.

Ideally I'm looking for a card that does not require a connection to the
PSU is 2 or 4GB and can support a 4K monitor.

Any advice would be greatly appreciated.

Radeon card recommendations

[Steve B via PLUG-discuss]

Looking for some recommendations on a discrete graphics card for a Dell
Optiplex 9020 and an HP z27S monitor. I'm moving to PopOS and would like to
get the most out of the monitor. If 21.04 moves to Wayland I understand AMD
is well supported whereas Nvidia does not support it.

Editing firefox.desktop

[Steve B via PLUG-discuss]

Is it possible to edit the firefox.desktop file such that I can invoke
"firejail --apparmor firefox -no-remote" as the default manner in which the
application starts? If so can someone point me to a guide or provide me
with an example? I'm having some difficulty finding a resource through
Google.

RJ11 keystone for old 3Com Intellijack

[Steve B via PLUG-discuss]

I'm rewiring a part of my home to extend the network into that room and
would like to reuse an old 3Com Intellijack I have laying about. Ideally
I'd like to connect an analog phone and tie it back into my asterisk
system. Would anyone know where I could source two, RJ11 keystones for an
old 3CNJ220?

I decided to go with Pi-hole as I believe I can get the most benefit from
that for my needs.

Raspberry Pi uses on a home network

[Steve B via PLUG-discuss]

I've been offered a Raspberry P 3B+ with a POE hat, but am having
difficulty deciding if I really need it. Currently the uses I can see for
it within my home network are:

1. Ubiquiti controller (replacing a cloud controller);
2. Pi hole;
3. Tor relay node;
4. Asterisk server.

Would appreciate some ideas for other possible uses.
