F33 just pretends to print
by Michael Hennebry
I have a Brother HL-L2360DL that I'd thought I'd finally managed to install.
I had to go to the Brother website to get a script to run.
The instructions for the script had the wrong name for it.
None of the default options for Brother printers came close.
The CUPS adminstration "web" pages say the right things:
Idle, accepting jobs, two completed jobs.
Nothing actually prints. Not even a test page.
The printer never comes out of deep sleep.
How do I fix this?
It worked with Centos 7, but I do not know what I did.
In my experience, there is no such thing as a small problem when it comes to
installing a printer on Linux:
Either it just works or it requires a mighty effort.
I am getting mighty tired of mighty efforts.
BTW how do I change the default from single- to double-sided?

Improper shutdown, now Kernel panic.
by murph nj
Hi all:
I've got an odd problem that I was hoping for some help on.
The laptop was previously working fine, I am running F30, updated regularly.
I've got an Acer laptop that has been shutting down suddenly. (I
suspect a bad battery, working on that.)
After a sudden shutdown last night, I now get a kernel panic on boot
right after "Starting Switch Root..."
I was able to boot from a USB stick, and was able to read the journal,
but I didn't see anything obvious to help.
I was able to get all of my data off of the (encrypted) disks, so
that's not a problem, but I don't want to just give up, and wash and
reload too quickly.
Any suggestions?
Thanks,

IP-routing fails after upgrade F33->F34
by Jouk Jansen
Hi All,
I'm using one of my Fedora machines as a router between 2 networks. The two
network devices on the machine are called enp0s25 and tun0. On F33 it worked
as expected. However, after an upgrade to F34 It looks like it does not work
anymore.
I tried to give the commands
firewall-cmd [--permanent] --direct --add-rule ipv4 filter FORWARD 0 -o enp0s25 -i tun0 -j ACCEPT
firewall-cmd [--permanent] --direct --add-rule ipv4 filter FORWARD 0 -i enp0s25 -o tun0 -j ACCEPT
But had no success (not even after restarting firewalld).
"firewall-cmd --list-all" gives the following:
FedoraWorkstation (active)
target: default
icmp-block-inversion: no
interfaces: enp0s25 tun0
sources:
services: dhcpv6-client mountd nfs rpc-bind samba-client ssh telnet
ports: 1025-65535/tcp 1025-65535/udp
protocols:
forward: no
masquerade: yes
forward-ports:
source-ports:
icmp-blocks:
rich rules:
The strange thing is that "forward" is always "no". (also the masquerade is
always "no" after restarting firewalld, although it is set with --permanent,
but can be set in run-time)
the forwarding variable is defined:
net.ipv4.conf.all.forwarding = 1
Can someone give me some hints on what I'm missing?
Regards
Jouk

pulseaudio -> pipewire
by Frank Elsner
Hi,
I'm a podcaster and therefore I need a functional audio environment.
Currently I use pulseaudio on a Fedora 33 system. Works for me.
Will this also work if I upgrade to Fedora 34?
Is there an equivalent to pavucontrol? I need it to adjust
the level of my external audio interface?
I'm heavy interested in any experience - especially pitfalls - before
I start the upgrade.
Thanks in advance,
Frank

Segmentation Fault using gdal with Python 3
by Clifford Snow
I'm getting a segmentation fault (core dump) when using the osgeo gdal
modules. Otherwise no problem.
I'm looking for some suggestions on how to troubleshoot this. I can't even
seem to find the core dump file.
For example, using the python interpreter with a simple program as:
>>> from osgeo import gdal
>>> quit()
Segmentation fault (core dumped)
I've reinstalled python3-gdal and gdal-python-tools with no help.
Thanks in advance,
Clifford
