The file browsers on Gnome/MATE haven't been able to create thumbnails
for video files on my computers in many years.  Nothing that I tried
made it work again, and I gave up long ago.

It was a handy feature being able to see some image inside of a
stupidly named video file, to work out which was which.


My experience is that sometimes I do get images from the video, and 
sometimes I just get a right-pointing arrow centered in an old-fashioned 
CRT TV screen.  I haven't been able to discern a pattern as to when I 
get which.  I do notice that the odds of getting pictures is better when 
the display is in grid mode rather than list mode.

What I think you're saying, and my impression even apart from your post, 
is that we can't realistically solve this SELinux alert problem.  This 
problem really has had me baffled.  The SELinux alerts seem to be false 
alarms; caja does what I want to do, and I can do those things other 
ways also.  So I'm inclined to go with what Ed said Tuesday:

> But if you're not having any problems it would be something
> that I'd ignore.

For what it's worth:
* I saw no SELinux alerts when trying totem-video-thumbnailer in the 
command line.  I forgot to mention this in this morning's post.
* I found this morning that SELinux alerts can show up when doing file 
renaming after having run Files in the same login session.  So Files 
does not stop further caja SELinux alerts.

* I patched my workstation (dnf upgrade) yesterday.

It is a video file.


the command was:
/usr/bin/totem-video-thumbnailer -s 128 file:///home/bill/KhongWe"...,
"/tmp/.mate_desktop_thumbnail.19V"

It truncated the filenames, but you could test run the command and see
what it does from the command line.  The first filename is the input
file, the 2nd one is the output of the thumbnail.

Re: on to letsencrypt

[Jack Craig]

ok, now we are getting somewhere!

So of the two servers that are listed the primary one, mine, does not
respond


 the secondary from AT&T is not responsive

 finally as you'll see below pinging t

Internal DNS is being returned as the external DNS number, that's a third
thing I need to fix up.

So I need to find out what's the correct AT&T DNS reference that I should
be using and
second I need to fix my own DNS so that I return the external not the
internal IP

Retest with improved  DNS parsing  method, thx again..

this could be a problem.

Re: puzzling SELinux alert.

That matches what Ed had called out that it was a GL* command.

I guess that also tells you why you did not notice the failing..

given a video file and an png file to output it fails on my system
also (and that is with selinux as permissive and as root, so it seems
to have many issues and is simply broken in most if not all use
cases), and I don't know that I have seen a video thumbnail in a while
in gthumb and similar tools.

And that tool seems to be very complicated for just creating a

someone took a gui app and made it work to generate one.  I sure

Others have given good answers, but let me show you how I parse it...

First one is not useful since it lives inside the domain. See:

So I check the other one:

Note the part "WARNING: recursion requested but not available", so it is saying 
that it is not authoritative for that domain.

So I check to see that it is the auth for its own domain:

Yup, good there. So you have two name servers listed. We need that glue record 
to figure out where one is and the other claims to not know who you are.

Canon MF642Cdw works as expected on F32 but fails on F33

[dwoody5654]

I was able to print and scan from Fedora 32 but when I upgraded to Fedora 33,
cups shows "waiting for printer to become available".

I am using the driver from Canon: linux-UFRII-drv-v520-usen-05.tar.gz.

The install.sh that is included looks for the following packages:
libjpeg-turbo
beecrypt
beecrypt-devel
libglade2
jbigkit-libs
libgcrypt
libgcrypt-devel
which are installed and current, and all the above packages have had a point
increase.

The install.sh also states that Fedora is supported.

Looking at the jobs page first message is "Rendering is complete", then 
"Waiting for printer to become available".

I called Canon and was told that the driver was not 100% Canon code and that
it was unknown when a updated driver would be available. The current driver
was released in 09/2020.

Any ideas on how to fix or work around,

Thanks,
David

The aegisub package is not distributed by Fedora, but rather by
rpmfusion.  You should file a bug and include the information above.
See here for how to do that:

https://rpmfusion.org/ReportingBugs

That will alert the package maintainer to the problem.  It's possible
that aegisub just needs to be rebuilt against the latest GTK library,
but the maintainer can help determine that.  Good luck!

Re: puzzling SELinux alert.

It seems to be running /usr/bin/totem-video-thumbnailer" so would be

It has an extension of .mkv so it thinks it is a video file or is it

the command was:

It truncated the filenames, but you could test run the command and see

Automount occasionally failing to auto-unmount

[Patrick O'Callaghan]

I use automount with systemd service units (not /etc/fstab) to mount an
external BTRFS filesystem (2 drives configured as RAID-1). There is a
timeout of 120 seconds of inactivity after which it should unmount.
This works *nearly* all the time, but sometimes it doesn't and I can't
figure out why. The drive is normally only used at 3am to run a backup
script, and logs show that this is working correctly, but when I check
in the morning I sometimes find the drive still mounted (shown by
'findmnt') even though nothing is accessing it, i.e. 'fuser' shows
nothing and 'umount' succeeds immediately.

If it matters, the actual timeout always seems to take 300 seconds. I
don't know if this is because BTRFS is keeping the drive alive,
flushing queues or whatever. It's not important in itself, just another
data point.

When I mount the drive manually, the timeout always succeeds (though
again after 300 seconds rather than 120).

Any ideas?

aegisub no more working after update...

[François Patte]

Bonjour,

I just update my system (fc-32) and aegisub is no more working: I can 
open subtitlefiles but not the corresponding video...


Here the message:

(aegisub:347417): Gdk-ERROR **: 12:08:25.195: The program 'aegisub' 
received an X Window System error.

This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 37349 error_code 2 request_code 150 (GLX) minor_code 24)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() 
function.)



I don't understand what it means and don't know what to do

Thank you for any help.

As I said earlier I do not need this functionality. I was just curious.
As long as the option to use a compose key keeps working for a standard
US keyboard I am happy as I just need the compose key for diacriticals
in the western European languages. A standard US keyboard works best
for me, NOT the US international or the UK one (I once tried the UK and
got some weird surprises). So I am certainly not 'going to create my
own layout'. My quest stops here. Thanks to everybody for replying.

This aside I am surprised these options are given in Gnome/KDE/etc 
without further explanation if it is so complicated and so dependent
on the choice of keyboard and/or it's layout.

And I don't understand the remarks about the keypad. I have never seen
a keypad with $/€/%/& signs (and I hate keypads (especially on laptops)
they make you sit "twisted" and on a loose keyboard they also take away
mouse room (and strain the upper arm muscles)). 
(And I have had enough occasion to use numbers: data analysis,
 simulation/research and such and the "top row" has always been
 sufficient for my needs).

This is in reply to Samuel Sieb but also to everybody who replied.

Sounds ok.  One test would be to see if an outsider can ping your
public IP that's supposed to allow traffic through.  Though, that will
only work if your system responds to pings.  The other test is for
someone to try and browse your webserver at your public IP.

Your public IP has to route through to your own server.  You will
probably have to explain your network topology to us.  Which I've seen
you do, in general, further below.

But is your public IP in a range of "customer" addresses, or public
IPs?  If it's within the range allocated to an ISPs clients, other
networks around the world will consider your IP to be risky.  You'd
find doing mail a problem, at least.

Yes.

By the look of things you need to reconfigure your DNS records.  Point
the A record for your domain, and the www. subdomain at your
webserver's IP.  Point your MX record at whoever handles mail to your
domain name.  Point the NS record at the name servers for your domain.

If you're also doing HTTPS, there will need to be port "443" passed
through, too.  I'm guessing "43" was a typo.  Both routers and your
computer will have to allow through the ports.  I see no point in
trying to be your own DNS server, though.

HTTPS *could* be a curly one to solve in your situation.  Certificates
can tied to an IP address.  While an outsider will be connecting to
your public IP forwarded through, your webserver will be using its
local IP, and the cert wouldn't match.  *If* the cert has to match your
public IP, you'd need to set your computer's IP to be your public one.

But that may not be the case with you.  Solve the DNS problem first.

While firewalls can prevent unwanted connections through a network,
they don't protect you from things that are done through the allowed
connections.  Your webserver will have to be able to handle people
trying to exploit it.

On my public website, the error logs are full of people trying to
connect to known exploits in wordpress and various other software
suites that people run on webservers.  I don't run those things, so
they just get errors.

You'll also need to be able to handle the legitimate traffic.  You'll
have multiple crawlers from search engines, including many you've never
heard of, as well as actual people browsing it.

That's why I don't run my public website on my own system.
