Easy way to keep my F35 laptop and desktop computers perfectly
sync'd. Rsync ?
by linux guy
Hi people.
These days I find myself constantly going back and forth between working on
my laptop and working on my desktop computer. It is very tiring setting up
the same applications twice, moving files back and forth etc.
I would like to find a way to keep my laptop and desktop computers
perfectly sync'd. Same applications installed, same setup, same files,
everything.
They are both running F35. Ideally I'd have a script that I would execute
from either machine that would bring it up to date with the other machine.
So I'd log into a machine, run the script and instantly be at the same
place I was with the other machine. Like I was working on the new machine
all along.
Thoughts on how to do this ?
Thanks

urgent problem: "NVIDIA kernel module missing..."
by home user
(f34)
I'm using my old windows-7 box to do e-mail.
I did my weekly patches ("dnf upgrade") an hour ago. After rebooting,
after the rightmost rectangle turns white, I get the message "NVIDIA
kernel module missing. Falling back to nouveau.". A few seconds later,
the 3 rectangles turn orange. Then the screens go black and nothing
further happens. I have to use the reset button on the top of the
tower. The behavior is the same no matter which of the 3 grub menu
Fedora entries I choose. No luck with the rescue mode (f30). I do have
an f31 live USB stick, but that has no e-mail client.
How do I get my f34 working properly? All I have to work with is
windows-7 (this is a dual-boot workstation) and the f31 live USB stick.
Please keep in mind that I'm a "home user" with no sys.admin. training.
My sys.admin. skills are *very* basic.

Bad USB drive?
by Robert Moskowitz
I have a 32Gb USB stick that is not showing up gparted.
I insert it and I see it in /dev as sdb. No partitions.
I tried fdisk:
# fdisk -l /dev/sdb
fdisk: cannot open /dev/sdb: No medium found
Is this dead? Is there some other tool I can use to get it working? If
there was ever anything on the drive, it would only be a copy of
something, so nothing to try and recover. Other than a nice 32G USB stick.
thanks!

mp4 to dvd
by Michael Hennebry
Any suggestions for converting mp4 files to VOB?
Even an example with mencoder might be useful.
Long long ago, I used mencoder for making DVD video files.
Lost track of the script I used.
I tried it again recently,
but getting all the options right was making my head swim.
At least one of the files I want to convert is 480x360@24 .

Dear Fedoers,
I'm planning to buy a NAS to backup my Linux boxes. I've spent few days at
looking for it on the Internet but I've some hard time to find a NAS that fits
my needs.
I intend to use it both the backup my data but also to keep consistent the
data on several linux-boxes. That is, the data are changed on one machine
(incrementally) back-upped and then restored from another one and vice versa.
As an inexperienced user, the characteristics I've pointed out are:
- ethernet based NAS optionally with wake-on lan (ie., the capability of
being turned on by a signal over the internet)
- Linux compliant ie.,
- it should be formatted in ext3/4 or other *nix file system to maintain all
the linux file details such as access rights, attributes, links, name
lengths/characters, ...
- rsync should be a viable solution to update/restore the backup
- files should be accessible over the internet possibly via ssh, https, or
mount over the internet - possibility to create multiple partitions, possibly also with multiple
file systems.
- RAID 5 or better the supported replicated storage should be at least 5TB
- optionally I would also like to have some way to limit/control/monitor
the accesses from the external, eg., via firewall (it will be on a
intranet and I can put a firewall on the modem but it would be nice to
have some extra control over security and privacy)
I do not have a net preference between mechanical and optical storage even
if I suppose that given the same storage size mechanical solutions are cheaper
and optical ones are faster. Probably cheaper (especially when associated with
more reliable) is better than faster.
From your experience do you have some brand/model to suggest? Or something
that I should consider that I didn't list?
For years, Mac and Windows users have been able to use high-end exterrnal RAID
arrays. e.g. for professional video. There are external USB-3 cases that claim to
support RAID on linux. Linux supports Thunderbolt 3, but I hadn't encountered
external TB RAID arrays with Linux support before retiring in 2018.
A search today found:
T4-S12L.TB3 Thunderbolt 3 Four Tray-Less SAS (12Gb) /SATA III Support RAID with LCD Control For Mac, Windows And Linux
https://www.datoptic.com/ec/portable-thunderbolt-3-four-sata-sas-ssd-raid...
P16-R64L.TB3 - 64TB Thunderbolt 3 RAID: https://www.datoptic.com/ec/60tb-thunderbolt-3.html
The specs say: "Must use Linux Kernel 4.13 with Ubuntu 18.04 & 17.10<http://www.areca.us/support/s_linux/driver/ubuntu/18_04.zip>".
I assume there are other vendors selling external TB3 or USB3 RAID boxes.
I like external RAID arrays because you can plug them into a host configured for
your needs and running the same OS as your other boxes. If you could afford it,
you could get external RAID arrays with vendor supplied drives. The vendor
gets statistics on drive performance for all their drives and I've heard of replacement
drives arriving with a note telling you which drive it was meant to replace..

Just a final thought….
Ever contemplated about a tiny storage ceph-cluster, each disk connected to an R-pi?
No spofs, and easier to maintain and upgrade…

Weird behavior of dnf install
by Miguel Lavalle
Hi,
I am installing MariaDB in Fedora 34 server with the following sequence of
commands:
sudo dnf upgrade -y
sudo dnf install -y mariadb-server mariadb-devel
sudo dnf -y install git vim
With this sequence of commands, I get the following installed:
$ mysql --version
mysql Ver 15.1 Distrib 10.5.13-MariaDB, for Linux (x86_64) using EditLine
wrapper
and I can successfully perform the initial setup of the root password:
sudo mysqladmin -u root password password
and continue with the rest of my installation.
However, if I change the sequence of commands to:
sudo dnf upgrade -y
sudo dnf -y install git vim
sudo dnf install -y mariadb-server mariadb-devel
What I get installed instead is:
$ mysql --version
mysql Ver 8.0.27 for Linux on x86_64 (Source distribution)
and the 'sudo mysqladmin -u root password password' command fails with:
mysqladmin: unable to change password; error: 'You have an error in your
SQL syntax; check the manual that corresponds to your MariaDB server
version for the right syntax to use near '() IDENTIFIED BY
'secretdatabase'' at line 1'
Could anyone shed some light on this?
Thanks!

F35 - yet another kernel crash
by Robert Moskowitz
I was downloading some mp4 lectures in Firefox and getting ready to
respond to the save to dialog when the system hung hard requiring a
power cycle. Couple not even switch to a non-graphic session to login
as root.
I had just done a dnf update that installed the new 5.15.11 kernel (was
running 15.10) along with new libvirt stuff (I run QEMU with one image).
ABRT says it does not have the traceback info to compose a report.
Second time this has happened.
lots of files in /var/spool/abrt/oops-2021-12-31-11:38:51-786-0 but what
to include in a bug report?
Sigh. Having problems with F35...

ntfs3 versus ntfs-3g, mount options
by George N. White III
Using an external drive formatted on a Windows system:
# mount -t ntfs3 /dev/sdc1 /mnt -o windows_names,uid=$UID,gid=$GID
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error.
dmesg has: ntfs3: Unknown parameter 'windows_names'
The drive ends up mounted using the old fuse ntfs-3g.'
Plugin the drive and go to Files, the drive is listed and I can mount it,
but I see the same dmesg entry and the drive is mounted with fuse.
My workaround was to add an entry in fstab:
UUID=99999999999999 /Volumes/WindowsBackup ntfs3
defaults,noauto,user,uid=9999,gid=9999 0 0
The "Disks" benchmark shows similar read rates, but average access time
goes from 23 on ntfs-3g to 18 msec using ntfs3.

f35 and NVIDIA entanglement
by Robert McBroom
My system has a NVIDIA GEFORCE GT 710 video card. It was working with
f33 and rpmfusion drivers. Updating to f35 installed a driver that was
for cards newer than the 710. Tried reverting to the 470.86 driver. All
I could get was a blank screen. Cleared the rpmfusion driver and tried
the NVIDIA binary 470.86 driver. The install seemed to go well but
restart gets only a blank screen. Same with the newer 470.94 driver.
Now trying to use nouveau.
Ran the sequence
rm -f /usr/lib{,64}/libGL.so.* /usr/lib{,64}/libEGL.so.*
rm -f /usr/lib{,64}/xorg/modules/extensions/libglx.so
dnf reinstall xorg-x11-server-Xorg mesa-libGL mesa-libEGL libglvnd\*
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.saved
The nouveau module did not load.
Went to /lib64/xorg/modules/drivers and ran
modprobe nouveau
lsmod|grep nouveau
shows
nouveau 2404352 0
mxm_wmi 16384 1 nouveau
video 57344 1 nouveau
i2c_algo_bit 16384 1 nouveau
drm_ttm_helper 16384 1 nouveau
ttm 81920 2 drm_ttm_helper,nouveau
drm_kms_helper 311296 1 nouveau
drm 630784 4 drm_kms_helper,drm_ttm_helper,ttm,nouveau
wmi 36864 4 hp_wmi,wmi_bmof,mxm_wmi,nouveau
ran
dracut -f
to update initramfs and did restart
graphical start does not connect to the server
System still trying to load nvidia instead of nouveau. Noted that
/etc/X11/xorg.conf was still that installed by nvidia. My systems with
ati cards do not have xorg.conf changed the name. startx still unsuccessful.
The Xorg.0.log file resulting is attached.
What can I do to get the system to give me a graphical desktop?
