lots of the time I want to pull data from shared files on windows
computers.???? The shares used to show up under network in any number of
file programs, caja, konqueror, etc.?? What protocol has replaced that
Something in the latest bunch of updates is triggering an rpm bug, or
rather, a librepo bug.
I ran a dnf upgrade on a bunch of machines. The first one segfaulted in the
cleanup phase. While I was pondering what to do about it, maybe a cosmic ray
hit an unfortunate capacitor in one of the RAM sticks perhaps, another one
splurted this out:
Install 5 Packages
Upgrade 159 Packages
Remove 4 Packages
Total download size: 514 M
Is this ok [y/N]: y

This strongly suggests a bone-fide bug. A rerun of 'dnf upgrade' succeeded
without any fanfare.
I'm fully updated out, but perhaps someone who has a bunch of updates to
install could run dnf upgrade under valgrind, and see what shakes out.
Have a old quad core system that I've had since Fedora 10 I believe.
Recently, upgraded to Fedora 31, and it was still seeing all 4 cores.
Run BOINC, and recently notice that it was only showing 3 cpus
running? Machine is one of the 5 computers I have at house, but is
headless and access remotely via VNC. Other systems all show the right
number of cpus after updates, so not sure what might cause the issue.
The results of lshw-gui shows the 4 cores, but the dmesg shows only
CPU 0 - 2. Didn't notice this until the 5.7 kernel change, but not sure
exactly which update caused the change.
Any ideals what could fix this, or how to get specific reasons it might
have happened. Other machines are newer, some dual and one other
quad core. So, just this one??

This is an annoyance rather than a problem, but it's been happening for
over a year and I finally decided to ask about it. This is a snippet
from my usual daily 'dnf update' run (with whitespace reduced for
Fedora Modular 32 - x86_64 52 kB/s | 22 kB 00:00
Fedora Modular 32 - x86_64 - Updates 51 kB/s | 22 kB 00:00

google-chrome 16 kB/s | 1.3 kB 00:00
google-chrome 32 kB/s | 3.6 kB 00:00 <-- duplicate
None of those repos are duplicated in /etc/yum.repos.d, nor is there
anything wrong with the repo files themselves, e.g.:
$ cat /etc/yum.repos.d/google-chrome.repo
So what's going on? Is this happening to everyone or is it just me?
I've got udev scripts that were working until I installed an update
today. Way down at the end of a chain of scripts udev starts, it sets
DISPLAY and runs a program (RepetierHost) when I plug in my
3d printer USB cable.
Did something change in udev to make it impossible to start
X11 programs now? It does run the script which invokes mono
to execute the .exe file, and that script produces zero
errors, I just don't have the program pop up on my screen
If I run the RepetierHost script from an xterm, it works fine and the
program starts up no problem.
This web page describes the scripts in detail:

I'm looking to make routing decisions based upon either the source or
destination TCP port and interface/destination IP, in the Cisco world
I'd do this via policy based routing.
I found an example using iptables
however this system is running firewalld and I haven't found an example
(yet) using firewalld.
Very specifically if I receive traffic on TCP port 1234 I do not want to
use my system defined default gateway, rather I want to use an alternate
gateway which will be via an OpenVPN tunnel. I would really like to go
one step further an if it was received on port 1234 AND interface X then
use gateway 1, if it was port 1234 and interface Y use gateway 2, not
sure how far down the rabbit hole I can go. What I am trying to avoid
is have an asymmetric routing condition when I have a firewall fronting
the different interfaces.

Yup. Rookie error. I got mixed up between the .ovpn extension, and the
"openvpn" plugin name.
