OK, just so that it's clear, you have a disk with documented
PARTLABELs, and after installing an OS with the d-i, the UUIDs
and PARTUUIDs have been altered.

You /seem/ to then be saying that /this/ is evidence that the
PARTLABELs have been altered. Is that your contradiction?

If the PARTUUIDs are altered, it would be interesting to know what
you are doing in the partitioner step of the d-i. Your posts have
only mentioned reformatting partitions, not repartitioning disks.

4.7MB is the size of the modules.* that are created during
installation, as I mentioned in my post. These are deleted
by purge but not by remove, whereas:

$ du -sh /lib/modules/5.10.0-22-amd64/
309M/lib/modules/5.10.0-22-amd64/
$ 

is the modules themselves, awaiting deletion. (Actually, this
particular listing is my live kernel.)

Host linams is the most burdened one, with five sets of modules.
I'm assuming that the kernels/initrds have gone from /boot. If
all five are still there, then the good news is that my first
post doesn't apply, and they've simply forgotten to remove the
1st, 2nd and 3rd oldest kernels (and it's best to use purge
for less clutter).

Another thing I usually do after doing an "apt upgrade" that installs a new 
kernel is:
aptitude -P purge '~o'
aptitude -P purge '~c'

The "-P" tells aptitude to ask permission before actually deleting anything.

I suspect that if you don't have the various directories under /var/,
you may not be able to use apt or aptitude or synaptic or the like, but
dpkg (in the form of 'dpkg -i /path/to/filename.deb') may still work.

If it doesn't, the only fallbacks that I can think of that would be
*more* likely to work - short of reinstalling Debian, anyway - involve
carefully extracting the .deb's contents into the correct root path, and
running any necessary follow-on scripts, *by hand*. And that would be
daunting even to me, though I understand that it's certainly possible.

This description seems to suggest that you're using a tool which is
trying to download the .deb file from a remote location. Those tools are
fairly likely to have problems if the directories under /var/ don't
exist.

Instead, I suggest that you try:

$ su -
# dpkg -i /var/cache/apt/archives/base-files_12_amd64.deb

(Or whatever the version number and architecture of your base-files
package may be; that's the oldest one I have on hand myself, from August
of 2021. You should probably be able to tab-complete the filename from
before the first underscore, but that depends on how your system is set
up.)

dpkg should, I think, have fewer dependencies on directory structure (et
cetera) than anything APT-based will have. It still might not be few
*enough*, but it's worth a shot.

Unfortunately I cannot install anything.  I used the command line and

I used su and sudo first.  It just keeps saying it cannot connect with 
the base from which I get updates, etc.  I used the reinstall on brasero 
and it just said that it was up to date.  I am so confused.

The Wanderer, in an earlier post (04/28/2023 at 19;02), suggested 
reinstalling the base-files package. I believe this is the correct

suggested you might need to reinstall other packages if they had

How to reinstall a package depends on how you maintain or upgrade your 
system.


If you use synaptic or aptitude, both have reinstall options that you 
can choose from the menu or submenu you would use for a new package 
installation.


If you log in as root on a terminal or terminal emulator to install 
and upgrade software, the command would be


apt install --reinstall  - for example,
apt install --reinstall base-files

If you use sudo in a terminal or terminal emulator to maintain 
software, use the above commands prefixed by "sudo" as you normally 
would for actions that need administrator privileges.


This should reinstall the version of the base-files (or other named 
package) that matches the most recently installed version.


I think the reinstall process might sometimes pause to ask you to 
choose between installing the default configuration file from the 
package or keeping an existing one that you might have changed. It 
should be safe to keep the one already installed.


If you have questions about any of this, feel free to ask, either

This at least i can contradict for a fact. VM is functional with known

(reformat is permitted) and the UUID's AND the PARTUUIDS were changed,
which was a huge surprise.

Just knowing about this, i can deal with the situation, but i think,
this is based on a false understanding of how a persistent

[roger . tarani]

Merci !

Je n'ai JAMAIS eu besoin d'installer spécifiquement ou de réparer la 
bibliothèque C (libc6) sur un hôte debian.

L'utilisateur a installé sa debian11 seul à partir d'une image ISO récente.
Je n'ai pas accès à sa machine. Je dois lui proposer une manip directe, simple 
et efficace.

Je crois comprendre qu'il s'agit d'un problème de dynamic linker.
Comment répare-t-on l'accès à cette bibliothèque libc qui est installée ?

Question bonus : que peut faire un utilisateur (juste capable de recopier des 
lignes de commande fournies) pour diagnostiquer ce qui a pu abîmer ce système ?


Extrait de mon message initial :

//
Sur l'hôte qui pose problème :
- libc.so.6 est bien présent. Et est donc inaccessible à l'exécutable.
- la commande ldconfig est introuvable. J'attends de savoir si 
/usr/sbin/ldconfig existe... Après vérification, ce fichier existe; Peut-être 
un problème de PATH ?...

Sur un hôte qui sert correctement libc.so.6 au même exécutable, il y a les 
liens symboliques suivants vers ld-2.31.so :

lrwxrwxrwx 1 root root 32 Apr 19 23:17 /lib64/ld-linux-x86-64.so.2 ->

/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 -> ld-2.31.so

Cela manque sur l'hôte qui pose problème.

Bonjour,

je réponds juste pour que tu ne te sentes pas tout seul mais mes
compétences sur le sujet ne me permettent pas de t'apporter une
contribution pertinente ;-)

quelques points hypothétiquement à surveiller:
- peut-être reconfigurer ou réinstaller libc6 sur le poste qui pose
problème puique les liens que tu cites semblent créés par ce paquet
- faire un apt policy libc6 pour vérifier les versions disponibles et
installées sur ce poste
- peut-être vérifier si quelqu'un a joué avec Apparmor ou SElinux sur
ce poste

t'es pas beaucoup plus avancé, je t'avais prévenu ;-)

I am sorry, i do not really understand, what you want to point to.
Your suggestions are coming without even knowing, what my needs and
options are, and involve alternatives that look unnecessary in my view.

Just to give you an idea: my OS partitions are 20 GB and that seems to
be a little too small, i had to delete stuff in order to keep the
systems in good shape.
I did abandon MBR years ago, and look with some bemusement at the many
places, whare that old technology still lingers.
Physical un-/plugging at the machines always involves getting external
help, due to a handicap.
Maybe your feeling is correct and i am in fact complicating things, i
don't know. OTOH, i am dealing with 2 dozen disks, server grade HW,
DUAL-CPU EPYC, 128 GB ECC RAM, nvme-ssd, aso.
My understanding is, that precautions are in order to keep the system(s)
up and running and useable for someoone, who is bad at typing.

I have installed many debian VM's before, all of them with a desktop,
and many of them are in use while i am investigating, how to
replace/upgrade the host OS. Do you get the idea?

But thanks for voicing your concerns, somthing i am trying to understand
and consider. Just keep in mind, that if a problem arises, i might not
be able too deal with, i will be cut off from everything, no paper based
calendar even exists. So i am careful.

 I do that because base64 would (must?) work on any OS and the
conversion from and to any other encoding is straightforward. As you
suggested, I am more friendly to the idea of including hashes of the
data payload, even though I think it is not that important, because
the actual big problem that corpora research people have is files with
exactly the same look and feel and the same content which have
different hashes (for example, pdf files). I have been thinking about
a way to compute hashes which resemble more faithfully, both,
structural and content similarity among files. Do you know of any way
to do such thing? The structural aspect should be "easy". It could be
handled as DAGs of some sort of XPaths.

 Even if not totally syntactic (so you can't functionally solve it
with some code), this is a relatively manageable problem, you would:

 a) take notice of the sites that do such things;
 b) sniff not only the http headers, but notice the file extension of
the file; and
 c) safe the file to a temp repository for the Linux util "file" to be
run on it ...

 Out of those heuristics you should be able to strategize around such problems.

Thank you for being this clear.
In the meantime i changed my plan somewhat (as stated earlier, i am now
willing to defer the resolution of the PARTUUID topic till later, in
order to see, if the upgraded GNOME will be able to serve me well, just
as the buster one did). Also, i wanted to be certain, that i will be
able to deal with the zfs upgrade.

Today, i found, that GNOME extensions are causing quite a bit of
trouble. The cause being, that the one extension, i have been using very
extensively ("Quick-Toggler") has been orphaned and is way out of sync
with current gnome-shell. That really hurts, as it had already been a
replacement for another extension, that had been orphaned in jessie
IIRC. - This is already the second time, that i have to find adjustments
in my workflow after an upgrade, due to changing functionality and lack
of compatibility. ... makes me somewhat unhappy, as i have been involved
 quite a bit in software rollout processes and we cared very much for
(paying) customer satisfaction. Ofc, this could be different in a
project based on the workforce from volunteers.

But it got even worse:
The site extensions.gnome.org let me know, that it cannot sync
extensions with my gnome-shell, because of a version mismatch. So i read
up a bit to understand, what is going on, and found the most concice
description here: (1)
Funny little detail: Ubuntu is suffering way less, because their
distribution is based on more recent version than debian stable is.

At least i saw some guy posting a video on youtube showing, how he
upgraded gnome-shell to experimental thereby creating a frankendebian,
something, i thought was an absolute no-go!

So i could not resolve the issue (You need to update
gnome-browser-connector to at least version 42.0), because the version
from debian is something like 10.1 or so.

Once again, i am happy to just playing around, not touching the
workhorse, that is still on buster, until i find a safe way forward.

zfs seems to be working fine on bullseye, the dev from the Quick-Toggler
published, that he abandonned the software due to his switch to KDE a
few years back.

Now, i am considering, if i should investigate the other desktops before
making a decision?

(1)
https://bugs.launchpad.net/ubuntu/+source/chrome-gnome-shell/+bug/1983851

Very sad, that the upgrade turns out to be rather difficult for a human
being like me, that is more or less isolated in his basement with no
friends sharing the passion for computing, or debian - for that matter.

So this is my todays report. Confused and undecided, i will head over to
get some rest now.
Ofc, i am curious to learn, how the crowd of "standard users" is dealing
with gnome extensions atm.

See the lpadmin manual for how to set up different queues with differnent
options on bpi51.

Glad you are now printing, but you really need to fix the CUPS installation.

And it did not exist until the lpadmin created it.

The 1st armbian, bpi51, /etc/cups/ppd does contain the PDF generator PPD
The 4th one, bpi54 /etc/cups/ppd is empty. All were installed with the 
same bullseye 11.6 installer. The other two are presently powered down 
in the middle of building a quad of 3d printers around them.


I might be getting on in the middle of my 88th year here, but I can

Re: Segfaults after upgrade to Debian 11.7 on virtualized systems with AMD Ryzen CPU

[NetValue Operations Centre]

Good thinking, trying that.

I worked through some of the cpu features, and when removing the line:



the test VM on 5.10.0-22-amd64 booted successfully.

https://www.kernel.org/doc/Documentation/x86/protection-keys.txt

"Memory Protection Keys provides a mechanism for enforcing page-based
protections"

"The kernel will send a SIGSEGV in both cases, but si_code will be set
to SEGV_PKERR when violating protection keys versus SEGV_ACCERR when
the plain mprotect() permissions are violated."

So, sounds like a memory protection system which can result in seg faults.

AFAICT the host system is running just fine with PKU feature on hosts 
running either 5.10.0-21-amd64 or 5.10.0-22-amd64, and the host kernel 
doesn't seem to affect the guest's behaviour either, only if the guest 
is running 5.10.0-22-amd64 with PKU passed through.


I don't know the best bug tracker to create a ticket in would be... 
https://packages.debian.org/bullseye/linux-image-5.10.0-22-amd64 ?

The ppd dirs are empty.

And if a copy/paste from this machine, hosting the printers fixes it on 
the other bullseye machines so these printers are available to whomever 
wants to use them, like geany or okular etc, can we create a cups bug 
entry? Perms on those empty ppd dirs are:

-rw-r- 1 root lp 335 Feb  6 23:35 subscriptions.conf.O
gene@bpi54:~$ ls -l /etc/cups/ppd
total 0

So it looks to me like cups, to add a printer, needs to be either root, 
ask a sudo pw, or be a member of group lp.


But group lp is bereft of any other members with "lp:x:7:" as its one 
and only member, but cups on these machines has yet to ask me for a pw. 
This looks like it could be part of the original show stopper problem?

Or, am I overthinking this again?

Looks reasonable. A similar command on the server should give a similar output.

The reason 'lp -d HLL2320D_coyote printer.cfg' failed is because CUPS is unable
to query the HLL2320D_coyote printer for its attributes. Printing from anything
else, such as Firefox, will also fail. CUPS on the bullseye machine appears to
be broken.

Your directory listings showed that both had a ppd directory, but you
didn't show the content of those directories. Since your error message
was specifically that it couldn't find the PPD, the first thing I'd do
is compare those two directories.

The modules aren't configuration files. AFAICT linux-image-*.debs
don't contain any. A small number of module.* files are generated
at installation time, eg modules.dep is probably the best known.

But if you create custom modules in the modules tree (which
I used to do with ndiswrapper), then they don't appear in
/var/lib/dpkg/info/linux-image-*.md5sums, so they should get
left behind by remove or purge.

The only other files that remove will normally leave behind
are those that are generated at installation time. The
package's postrm script attempts to delete these, and lastly
the /lib/modules/$version/ directory if it is empty.

David.

A client.conf is unneeded on a well-behaved CUPS system that obtains info

Also, purging the current kernel is not nearly as dangerous as
it sounds: in many (most) cases, the system will keep working just as
well as before (IIUC even hibernation will keep working since you can
now resume using a different initrd than the one you're resuming
to).  The main downside is usually that you won't be able to access
devices that require different drivers than the ones already loaded.

Hello list,

after receiving so much good advice, i finally made up my mind and began
playing through the installation (debian bullseye, current stable) in my
simulation-VM in order to learn about the pitfalls to avoid. After more
than a dozen tries, i am running out of fuel, because i am continuously
running into problems, that i would have preferred to circumvent.

At first, i picked a debian (debian-11.6.0-amd64-DVD-1.iso), as the 11.7
release was not yet out), and installed from there, choosing the Expert
Install. The main reason was, that i was expecting to be invited into
customizing the system picking software to install by hand.

But at first, i ran into a multitude of problems with the partitioning
tool, even though the system was already properly configured (GPT +
EFISYS + OS + Swap + several other partitions booting in UEFI style).

For example, when i allow the use of the swap partition, it gets
reformatted and another PARTUUID is assigned to it, leading to failures
booting other systems from that disk. OTOH Disallowing its use for the
time being leads to install failures due to the 4GB of RAM apparently
not being enough for that VM.

Another problem, similar but distinctly different happens around the OS
partition. Whenever i gave it to the installer, it reformatted it while
changing the PARTUUID, again leading to failures in the boot process of
the other partitions... Until i discovered this workaround: Assign the
partition to ext4 and the mountpoint / but not allowing to delete its
content (as that would induce the reformatting). Instead, after
finishing partitioning, i asked for a shell and from there manually
deleted ONLY THE DATA from the partition(s) used. Then installation
progressed further.

BTW: Apparently, this was the only way to keep the PARTUUID, as deleting
the data by overwriting with zeroes lead to the installer overwriting
the fs structures making another mke2fs necessary.

But the worst of all, was the software selection: Even though i asked
for debconf priority low, i got only a few checkboxes to pick from. And
choosing GNOME did automatically install software i neither need nor want.

But omitting GNOME from the list lead to a system failing to boot with
tons of messages stating the absense of all kind of gnome parts.

So, just in order to make some progress, i had to willingly and
temporarily kill the bootability of other partitions in order to have
the install terminate without failures.

At that point, i decided to try the netinstall, as it is now available
with release 11.7 and i did expect there to be more choices. And when
even that one failed to boot without GNOME, i even did check the
sha512sum to make sure, i was using the proper one. - I did!

Now, i am confused. Many years ago, the expert installer was very
difficult to use and did provide very many choices (and liberties to
spoil the fun). Now, i dont seem to be able at coming to the stage,
where i can seriously test more complicated things (like multi-boot,
zfs, and other things) that make up my current host in its buster version.

It is quite obvious, that i am lacking SOME kind of understanding,
because what i am trying to accomplish should really be quite easy, but
i am only experiencing troubles.

Oh, as a side note: As a nicety of my setup, i can use bash scripts,
that work well from my main OS, or from the simulation VM which can be
used to test functionality before it is rolled out to the host. That is
why, i am relying/insisting on absolutely identical PARTUUIDs inside
that VM.

Now, i am really curious as to how to get to a proper system without
having to go through the baby-steps beginning with debootstrap, and all
the millions of configuration steps, that i did not even bother to list.

I am really interested to understand, in which way i am creating all
those problems for myself. Could it be related to the fact, that i am
accessing the net fom a VPN? - I don't think so.

Any suggestions/questions/hints from the power-users in here?
... would be wildly appreciated ...

Looks reasonable. A similar command on the server should give a similar output.

The reason 'lp -d HLL2320D_coyote printer.cfg' failed is because CUPS is unable
to query the HLL2320D_coyote printer for its attributes. Printing from anything
else, such as Firefox, will also fail. CUPS on the bullseye machine appears to
be broken.

[...]

A possible way forward is to execute

  sudo lpadmin -p HLL2320D-RAW -v ipp://192.168.71.3:631/printers/HLL2320D -E 
-m raw

and try

  lp -d HLL2320D-RAW printer.cfg

Autoremove removes packages, it does not purge. The difference is that
remove leaves configuration files in place. So you have a tedious bit
of "apt purge linux-image-… [linux-image-…]" etc. ahead. Just be sure
to not purge the two most recent kernel packages, and especially not
the kernel you are currently running on.

See above.

I conjecture that the reason updating the kernel removes rather than
purges old kernels is in case the user has a custom kernel and wishes
to preserve those customizations.

Changing TTL after socket is connected

[Tim Woodall]

Hi,

If I have a SOCK_STREAM that is connected and working, is/should it be
possible to change the TTL before sending the next packet? (C++
applicatiom)

If I have to I'll resort to SOCK_RAW, but I don't want to have to deal
with all of the required headache of setting up a TCP connection so I
can mangle the TTL on a single packet if I don't need to.

My testing suggests that I cannot change the TTL of a connected socket -
but I'm not sure if that's because I cannot do this or whether it's
because I'm doing something wrong, this isn't something I've attempted
before...

setsockopt(sock, IPPROTO_IP, IP_TTL, , sizeof(ttl)) succeeds, but
setting a ttl of 1 - when the target is 15 hops away, and the packet
still gets there!

I think I see the same issue. I just looked at /usr/lib/modules and see
one extra directory for kernel that isn't installed (5.10.0-18-amd64).
Because this issue seemed familiar I looked at my bash command history
and that has me cd'ing into that directory and doing a du command there
and then deleting stuff. So I guess I've also resorted to manually
cleaning it up in the past.

Re: Re : date de sortie prévisionnelle de Debian 12 Bookworm: le 10 juin 2023

[Ro Bou]

Bonjour!

J'ai aussi fait l'essai de bookworm. Résultat pas concluant dans mon cas.

Je suis en multi boot avec le windows 10  pré-installé, une 
debian-facile et un disque usb externe  de 4 tb pour des sauvegardes.


Au redémarrage de l'installation le grub n'affichait que la bookworm.

Après quelques heures de boulot pour revenir à la situation précédente, 
le démarrage sur la debian-facile demeurait lent. J'ai donc supprimé la 
bookworm et réinstallé la debian.


Je vais attendre quelques mois pour le prochain essai.

Pour info, lors de l'installation j'avais utilisé le mode expert pour me 
permettre d'installer le grub sur la partition root mais je n'ai pas 
trouvé la façon de faire. Je vais fouiller la question.


Bonne journée,

Roger

THe network is probed and the dnssd backend of CUPS find the same four printers 
as
'lpsta -l -e' does.

disk usage for /usr/lib on bullseye

[Bonno Bloksma]

Hi,

On my "new" Bullseye machines the root volume starts to fill up. The cause 
seems to be the /usr/lib folder.
On my older Buster (10.13) machine the total /usr directory is 701M, the 
/usr/lib folder is 260M
In my /usr/lib folder on Buster is NO /usr/lib/modules folder

On my Bullseye machines the /usr/lib folder is 2+GB on the machines that have 
been operating for a while and 1+G on a machine that has been operating for a 
shorter while.

The cause seems to be the folder /usr/lib/modules# 
linams:/usr/lib/modules# du * -sh
4.7M5.10.0-10-amd64
4.7M5.10.0-11-amd64
4.7M5.10.0-12-amd64
4.7M5.10.0-13-amd64
4.7M5.10.0-15-amd64
4.7M5.10.0-16-amd64
309M5.10.0-18-amd64
309M5.10.0-19-amd64
309M5.10.0-20-amd64
309M5.10.0-21-amd64
309M5.10.0-22-amd64
4.7M5.10.0-7-amd64
4.7M5.10.0-8-amd64
4.7M5.10.0-9-amd64

And
linutr:/usr/lib/modules# du * -sh
4.7M5.10.0-16-amd64
4.7M5.10.0-17-amd64
309M5.10.0-18-amd64
309M5.10.0-19-amd64
309M5.10.0-20-amd64
309M5.10.0-21-amd64

And
lola:/usr/lib/modules# du * -sh
4.7M5.10.0-13-amd64
4.7M5.10.0-19-amd64
309M5.10.0-20-amd64
309M5.10.0-21-amd64
309M5.10.0-22-amd64

Guessing on what I see these are libraries for older kernel versions. I usually 
clean up older kernel versions by using
# apt autoremove"
All 3 servers have 1 older kernel version installed according to apt autoremove.


Why is this stuff there? Can I delete it?
If I can delete it, is there a proper way to clean it up or do I just rm 
/usr/lib/modules/5.10.0- for the older kernels?

Is this a BUG in Bullseye?


p.s. Looking at this I just noticed I need to do an update on lunutr, I will 
dis that right after sending this mail ;-)

You may care to take note that 'lpstat -a' and 'lpstat -t' only show

goes

for the Printers section at localhost:631.

Local printers can also be auto-setup by cups-browsed. You do not have it

matter,

You have exactly four (not five or six) print queues manually set up on
the CUPS server coyote (192.168.71.3). It is assumed that when sat at
coyote it is possible to print to any of Brother HL-L2320D series, Brother
MFC-J6920DW, HLL2320D and  MFCJ6920DW _tray_2. Im particular - can you
print to HLL2320D from the server?

Ugh, that sounds like a bad idea.

I'd love to hear the backstory about why that was done.

Perform a `chown -R user:group /home/user/*`. Then perform a `chmod -R
o-rwx /home/user/.ssh/`. (You only need to remove 'other' access).

Root is usually not allowed to login via ssh. Login as a regular user,
then do something like `sudo -i` or `sudo su -`.

If you want to allow root logins, I believe your sshd_config needs to
be updated. Here's the one I set to disallow root. You should do the
opposite:

$ cat /etc/ssh/sshd_config.d/20-no_root_login.conf
PermitRootLogin no

I also only allow PublicKey methods:
 cat /etc/ssh/sshd_config.d/10-pubkey_auth.conf
# Disable passwords
PasswordAuthentication no
ChallengeResponseAuthentication no
KerberosAuthentication no
KerberosOrLocalPasswd no
GSSAPIAuthentication no
UsePAM no

# Enable public key
PubkeyAuthentication yes

Is "user" one of the accounts with UID 0?  If so, this is absolutely
expected behavior.  You're asking chown to change the owner to UID 0,
and it does so (which is a no-op).  Then you're asking ls to show you
a textual representation of the owner.  Obediently, ls uses the first
account that matches this UID, which happens to be named "root".

Impossible to change ownership of a file to user when user is UID 0

[Pierre Willaime]

Hi,

I am unable to connect via SSH without password (ssh-copy-id was launched) to a 
VM running Debian Stable. 

After some investigations, it is most likely a permission issue

May  1 15:32:42 vm sshd[131848]: debug1: trying public key file 
/home/user/.ssh/authorized_keys
May  1 15:32:42 vm sshd[131848]: debug1: fd 5 clearing O_NONBLOCK
May  1 15:32:42 vm sshd[131848]: Authentication refused: bad ownership or modes 
for directory /home/user

On this system (not installed by me), my user has an UID and GID of 0 in 
/etc/passwd. Several users share root privileges like this on the server.

After a ssh connexion (it is working with password authentification) done as 
'user'

$ ssh user@server
user@server's password: 

I am directly connected as root

root@server:~# whoami
root
root@server:~# su user
root@server:~# whoami
root

.ssh files of user directory are owned by root

# ls -la /home/user/.ssh/
total 4
drwx-- 2 root user  29  1 mai   15:38 .
drwxr-xr-x 3 1001 user 106 11 févr. 11:10 ..
-rw--- 1 root user 395  1 mai   15:38 authorized_keys

I tried to change the owner of the file authorized_keys (I guess if it matches 
the user used in ssh connexion command, it will allow the ssh connexion by 
keys) but chown fails silently.

root@server:~# chown user /home/user/.ssh/authorized_keys 
root@server:~# ls -la /home/user/.ssh/authorized_keys 
-rw--- 1 root user 395  1 mai   15:38 .ssh/authorized_keys

I tried a `chattr -i` on the file, unsuccessfully. 

If I launch again ssh-copy-id with root@server instead of user@server, I can 
connect without password. But I would prefer to connect with my user.

What is my best move here?

There you are! CUPS sees all four print queues shared by coyote. At this
stage we are golden. Note that all four are designated as "network".

This is a manual queue (permanent) set up locally on bpi51. It isn't of any
further interest.

You may care to take note that 'lpstat -a' and 'lpstat -t' only show local
printers (permanent) and not those that are on the network. That also goes
for the Printers section at localhost:631.

Local printers can also be auto-setup by cups-browsed. You do not have it
installed/running. Thar's OK; there isn't any obligation (or for that matter,
any need) to use it. Having mentioned it, we will now completely put it out
of our minds.

The last epson I had that worked with linux was a 4 color C82, well over 
a decade ago. Then it looks as if they started making windows only 
printers because all the normal printer stuff was moved from the driver 
in the printer and put into the windows driver, leaving only the ability 
to put a drop of the chosen color at the chosen xy spot on the paper in 
the printer.  That and the constant battle to keep the nozzle unclogged 
got tiresome and limited the last printer I bought to about 2 months 
life. So that was replaced by a Brother color laser, which worked well 
for around 4 years, then slowly lost its corona wire voltage, an easy 
enough to diagnose problem for me as I am a CET, but brother refused to 
sell me a board despite the fact that I am a CET, fully capable of 
handling that high voltage item. So I brought home their biggest inkjet. 
That was about 8 years ago, and it is still pumping out full color 
images on paper up to tabloid size. A huge device, its also a scanner 
for 11x17 tabloid. I also have a much faster HLL2320dw a B laser that 
does duplex on copy paper at 19 pages a minute. And running on linux, 
using the drivers they supply, both run to their full capabilities.


Obviously I am now a Brother fan and I believe in supporting the makers 
who support us. Glaringly obvious in my previous post. But apparently 
this person doesn't want to admit a mistake was made, and the only way 
to solve it is to run an all windows house at much more cost than buying 
another printer that is supported would be.  Brother's consumables cost 
less per page than epson so you get the difference back over time and 
reams of paper.


This may be a duplicate of what wallmart had for sale at $31.95 3 or 4 
years ago, and which I saw the epson label and drove the cart right on by.

I now found out, that the 5.10.0-22 kernel boots fine, if I set the CPU

In that case, "virsh dumpxml" tells me about the VM's CPU:

On the other hand, if I set the CPU model as "copy from host",
booting the 5.10.0-22 kernel results in the reported segfaults.

Re: Evolution email (problem?) (IMAP, Gmail, email compacting)

[rhkramer]

Oh, I meant to add that compacting is typically useful when record (email?) 
storage is in something like an mbox file -- it saves the need to rewrite the 
file each time a single file is deleted (for example).  

On the other  hand, with storage in something like mdirr files (right name -- 
one email / record per file) it is not really relevant (unless those records / 
emails are indexed by some other indexing system that stores pointers to all 
of those records).

In (older versions?) of kmail, with mbox storage, compactiing is necessary to 
reclaim unused space after deletions, and there is an option in the context 
menu for (most) kmail folders to initiate compaction.

The definition of compacting as I "grew up" with it (not sure where I first 
encountered it is the idea that in some applications, the act of "deleting" 
something doesn't actually delete it from the file, instead it is marked for 
deletion (and no longer visible to the user).

Compacting actually deletes that thing, and shrinks the file to avoid any 
wasted (empty") space previously used by those deleted things.

I suspect I first encountered that back in the early days of DOS based 
databases, even prior to dBase II.

If you change the topic, start a new thread.

Writing is often meant for others to read and understand (legal documents 
excepted?) -- make it easier for your reader by various means, including 
liberal use of whitespace (short paragraphs, separated by whitespace / blank 
lines) and minimal use of (obscure?) jargon, abbreviations, acronyms, and 
references.

If someone has already responded to a question, decide whether any response

A picture is worth a thousand words.  A video (or "audio"): not so much -- 
divide by 10 for each minute of video (or audio) or create a transcript and 
edit it to 10% of the original.

A speaker who uses ahhs, ums, or such may have a real physical or mental 
disability, or may be showing disrespect for his listeners by not properly 
preparing in advance and thinking before speaking. (That speaker might have 
been "trained" to do this by being interrupted often if he pauses.)  (Remember 
Cicero who did not have enough time to write a short missive.)

A radio (or TV) station which broadcasts speakers with high pitched voices (or 
very low pitched / gravelly voices) (which older people might not be able to 
hear properly) disrespects its listeners.   Likewise if it broadcasts 
extraneous or disturbing sounds (like gunfire or crying), or broadcasts 
speakers using their native language (with or without an overdubbed 
translation).

A person who writes a sig this long probably has issues and disrespects (and 
offends) a large number of readers. ;-)

It means that person has put you on their ignore list, or killfile, or
whatever it's called in their mail reader.  They have chosen never to
see anything you write, ever again.

If you leave "Debian Desktop" selected, the installer chooses a Desktop
Environment for you.  And guess which one it chooses by default?  That's
right: GNOME.  Assuming you're using a standard installer image, and
not one that has a DE in its name.

I have no idea why this confusing default auto-selection exists, but
it does.

Oh, goody. I only brought mbox up as an attempt to explain how such
a kind of unser interface (mark for deletion, then bulk expunge/

After that, users might expect that kind of interface regardless of
the actual storage backend, so many mailers offer it.

This interactive step is performed by "apt install wireshark" actually.

I even did a full logout/login from Mate to make sure my user picks up

Turns out these steps are not sufficient now.

I wonder if Wireshark uses `dumpcap -D` internally to show the list of
interfaces? I can do this now from my user account:

$ dumpcap -D
1. enp3s0
2. any
3. lo (Loopback)
4. bluetooth-monitor
5. nflog
6. nfqueue
7. dbus-system
8. dbus-session


but still cannot see those interfaces in the Wireshark GUI.

Thank you for encouraging me. A good night sleep did help as well.
Following your advice, i retried a fresh install. This time round, i did
permit the reformatting of everything, and just noted a new todo to
resolve that later. But ...

The install succeeded, an sshd is running ON a machine with GNOME and
all its (un-) pleasant surprises like: firefox, openoffice, and much
more. But i know for sure, that i deselected it and only left Desktop +
ssh server. I guess, that means, that the installer chose gnome as its
preferred desktop.

Ok, i will go on from here, as i certainly want a DE + GNOME, only the
standard tools, i wouldnt have all of them.

==

One explanation of my choice to stick with PARTUUID's:
In my overall stategy of using my computer, i am sometimes copying (dd)
whole partitions into a backup, a secondary partition or a VM, which can
easily lead to difficulties, if the same LABELS were used, which can be
changed, but reside INSIDE the partition itself, whereas PARTUUID's
reside in the GPT, which is not affected on partition copy operations.
Thus my choice was related to convenience, avoiding some adjustments
after partition copy operations. Only the installer interferes with the
so called "persistent" PARTUUID's, which i regard as being offensive (or
ignorant - for that matter).

I am going to fix that later (on my machine), returning to my preferred
fstab format of using PARTUUID whereever appropriate.

All this command does IMHO is create the "wireshark" group with sufficient
privileges to capture packets. I clearly remember answering "Yes" to
that question while installing Wireshark.

That is why I wrote in my first mail that dumpcap can list interfaces
and capture packets when run from my account:

$ whoami ; dumpcap -D
vas
1. enp3s0
2. any
3. lo (Loopback)
4. bluetooth-monitor
5. nflog
6. nfqueue
7. dbus-system

Bizarre, car un paquet de binaires sont liés à libc6.

Je ne réponds que sur l'aspect saisie du mot de passe: oui, avec 
LUKS/Cryptsetup, il y a moyen de déverrouiller un système de fichiers 
par l'insertion d'une clé USB plutôt que par la saisie d'un mot de passe 
(le même principe que l'insertion d'une clé physique dans la serrure 
d'une porte). Tu trouveras des précisioons sur le net.

A priori c'est pas le manque d'évènement détecté par le noyau qui pose 
problème, ça semble détecté.
il y a ici un exemple d'un type qui aurait réussi à faire marcher une

Monthly FAQ for Debian-user mailing list (unmodified April 1)

[Andrew M.A. Cater]

Debian-user is a mailing list provided for support for Debian users,
and to facilitate discussion on relevant topics. 

Some guidelines which may help explain how the list works:

* The language on this mailing list is English. There may be other mailing 
  lists that are language-specific, for example, debian-user-french 

* It is common for users to be redirected here from other lists, for example,
  from debian-project. It is also common for people to be posting here when 
  English is not their primary language. Please be considerate.

* The list is a Debian communication forum. As such, it is subject to both 
  the Debian mailing list Code of Conduct and the main Debian Code of Conduct
  https://www.debian.org/MailingLists/#codeofconduct
  https://www.debian.org/code_of_conduct

* This is a fairly busy mailing list and you may have to wait for an
  answer - please be patient. Please post answers back to the list so
  others can benefit; private conversations don't benefit people who
  may be following along on the list or reading the archives later.

* Help and advice on this list is provided by volunteers in their own time.
  It is common for there to be different opinions or answers provided.

 * Please try to stay on topic. Arguments for the sake of it are not
   welcome here. Partisan political / religious / cultural arguments
   do not belong here either. Debian's community is world wide; do not
   assume others will agree with your views or need to read them on a
   Debian list.

* There is an FAQ on the Debian wiki derived from some questions asked on this
  list at https://wiki.debian.org/FAQsFromDebianUser

* One question that comes up on almost all Debian lists from time to time
  is of the form:

  "I have done something wrong / included personal details in an email.
   Could you please delete my name / details / remove the mail"

Practically, this is impossible: the mailing lists are archived, potentially
cached by Google and so on.

Unfortunately, there is nothing much we can do to ensure that all copies
anywhere on the Internet are deleted. Asking to do this may only serve to
draw further attention - the so-called "Streisand effect"
See:  https://en.wikipedia.org/wiki/Streisand_effect

Problems?

Complaints about inappropriate behaviour should be referred to the
Debian Community Team .

Inappropriate behaviour on the list may lead to warnings; repeated bad
behaviour may lead to temporary or permanent bans for offenders.

When installing you have to stop on your first problem. The others could
be created from it. It's longer but easier to cope with. So give us full

I thought we were talking about IMAP protocol access to Google? In
which case Evolution isn't storing email in any format [1], it's
accessing it on a remote server. Evolution does have an 'On This
Computer' email account, don't know what format it uses for that. In
Evolution you can also create email accounts where email is stored
locally in maildir or mbox format. I used maildir some years ago to
have an email archive of some mailing lists. 

[1] Well, Evolution does cache email in ~/.cache/evolution/mail
which seems to involve SQLite database and a file for each email. If
you want to free that space you can just 'rm -rf ~/.cache/evolution'
but I guess if you have 'download for offline use' configured or
actually look at the remote email folders again it will re-download
them.

Make / mark the dot as string with " character.


|$ echo 44.33.2.1 | awk -F\. '{print $4 "." $3 "." $2 "." $1}'
|1.2.33.44
