Subject: Re: systemd-resolved, split dns, & vpn setup
Oh so now I have learned something new.
I thought that because I was a Domain owner, I had to do the translation from my public IP to my local DNS name
You can do, but you don’t MUST do it.
I to have a split horizon, but updating records at my dns-provider is a rather masochistic exercise. Besides, it changed hands four times.
in as much as networksolutions.com<http://networksolutions.com>, my domain registrar provider, has already the IP and host name then
I don't need to provide that so let me trim off that external. zone I'm assuming that I still need to provide service for the 10.0.0.0 internal addresses, but that could just be covered by my /etc/hosts file right?
Only if you serve it to a single machine in your lan, /etc/host is a sensible option.
If you have multiple machines in your network, bind remain the ultimate solution (imho).
Besides, hosts is only useful for translating names to numbers and vice-versa. Anything else: (txt, srv, etc) not possible. So: “viva bind!”
With this new bit of information, I should be able to run a minimal configuration as you earlier outlined
I was trying to throw in everything plus the kitchen sink. I'll start ripping the plumbing out of named.conf;
see how little I can get away with.
Once again thanks for your time!!

In very few cases the primary name server for a public DNS record will
be on a home computer. It'll usually be done where you register your
domain name. Though you can shift it elsewhere. You can renew a
domain name and host it with a different company. You can have a
company host your website, and they can also host your DNS records.
For what it's worth, if they do your mail and website through something
like cpanel, they'll probably want to host your DNS records, too, so
their cpanel software can control any changes the DNS records.
You can run your own slave name server, that follows what the public
one does. This can be handy, but not essential, to keep an eye out for
anything that goes wrong.
If you want to run dynamic DNS, so you can log into your home computer
from somewhere else on the net without having to know your IP, that's a
different thing, again.
But, if you want to be your DNS server for the whole world, they have
to be able to connect to you. Traffic has to be able to get through.
And you will need a fixed IP.

invisible application after upgrade.
by home user
(f33; gnome)
I just finished upgrading from f32 to f33.
When I click the gnome "Activities", I no longer see "caja". When I use
the gnome activities search thing, it does not find "caja". But dnf
shows it installed and up-to-date. Before today's update, caja was
easily available through the gnome Activities. How do I get caja back
into the gnome Activities, and visible to the gnome Activities search?
Thank-you in advance.

Newbie Info - Linux and Intel
by David
If one goes to the Intel website and does a search on "Linux," they will
find several articles, that may be of interest to someone interested in
Linux drivers for Intel components.
For example.
https://www.intel.com/content/www/us/en/support/articles/000025890/ethern...
While their pages do not mention Fedora, there are some that mention RHEL,
which should apply. Feel free to elaborate, if you have insight into all
that.
Any drivers that claim they are compatible with Ubuntu are likely compiled
for Debian Package Manager. So they will not work in Fedora. I do not
know if there are generic drivers that work in both .rpm and .deb. Can
someone please elaborate on all that ?
Is Intel support for Linux excellent ? or amazing ?
I would say that their support for Fedora is lame, compared to their
support of Clear Linux. And, that their support of Red Hat or Fedora is
not as good as their support for Ubuntu.
Intel's community forum does allow specific questions about Fedora. For
example:
https://www.intel.com/content/www/us/en/search.html
If that link does not work, try a general search there, such as "Fedora
32." There are hundreds of post there from Fedora users asking for
troubleshooting help, going back several years.

Trouble with firewalld
by Jonathan Ryshpan
Looking through the system logs (journalctl --boot), I stumbled on the
following error messages from firewalld; it looks like the function
iptables-restore is called fairly frequently, generally after the
system wakes up from sleep, and never succeeds. The intervening lines
vary.
Is this something to worry about?

A problem with Fedora and Wine
by Francisco Tissera
Hello everyone,
I don't know if this has happened to anyone, but below is my problem:
When I launch an application with Wine, and press any key, this happens:
wine: Unhandled page fault on write access to 00000000 at address
0336199B (thread 0124), starting debugger...
and the application itself crashes.
I experienced this with both Fedora 33, and rawhide.
The wine version I'm using at the moment is 6.3-1
Thank you for any answer.
Best regards.
Francisco.

M2 on laptop
by Patrick Dupre
Hello,
I wanted to install fedora 33 on a laptop with a M2 SSD 128.Go, but it is not
recognized by fdisk (fedora live WK).
Is a driver missing?
The SSD is recognized by he bios.
Thanks

Access HDMI outlet from podman container
by Meikel
Hi folks,
I became owner of a QNAP TS-269 Pro NAS and as a playground I did
install Fedora Server 33 on it. There isn't installed any GUI (for
administration I use ssh or cockpit), and I' m wondering if it could be
possible to run Kodi inside podman container and give it access to the
HDMI outlet so that I can use it as a media center? Could such a setup
be possible? There is a tool x11docker available that connects a podman
container to an X server, but that's not what I have, because for
x11docker I need to "log into the X GUI", which is not the case here.
Regards,
Meikel

What sets QT_IM_MODULE in F33?
by Robert G. (Doc) Savage
Using Fedora 33 with MATE desktop...
I'm working with the developer of a very handy RPN calculator app
called rpCalc to figure out why it doesn't work for my regular user
'doc' but works perfectly for a newly created user 'test'. The
developer strongly suspects a Qt5 setting. We have narrowed our search
to my local environment:
$ env | grep QT
QT_IM_MODULE=xim
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCALE_FACTOR=2
The developer believes the first (set to =xim) is causing rpCalc not to
function at all, and that the next two cause the font sizes on the
calculator buttons to be oversize.
I'm looking for one or more config files -- probably in my home
directory -- that set these variables. Talk about looking for a needle
in a haystack.
Is there a cat | grep command (or equiv) that can recursively look for
"QT" in all files in my home directory -- including hidden files? It
would have to be able to output the full path to any files in which
"QT" is found. Unfortunately cat does not support recursive searches.
