/tmp (and /var/tmp/) should have the following permissions and rights:

apt runs its I/O processes as a different user "_apt" and if /tmp does
not have the sticky bit set, then it cannot create any files there,

Depende de cómo esté configurada la red.
Si tenés un enrutador de, por ejemplo, Fibertel con dirección IP

Y en tu servidor, un script que actualice a nsupdate.info la IP que tengas.

I'll second this and offer a couple of additional comments.

On Debian Buster with Gnome, pretty vanilla except for google-chrome and
some R packages from r-cran, I downloaded the Zoom .deb package and
installed it [1], as root, in /opt, with no dependency issues that
another responder noted might interfere. The only issue of any
consequence was that on a 15 inch 3840 x 2160 screen, the boxes were
quite small and the print in the window titles and popups was too small
to read w/o a strong magnifier. It took a while, but of searching in
Zoom's FAQs provided a solution [2].


Security issues whooped up in the media seem to fall mostly into one or
more of three boxes:

Affect (or are known to affect) only Macs;

Have been corrected, some quite a while ago;

User error (e. g., setting up for zoom-bombing by failing to use a
password, using an obvious password, or letting the password leak.

Some appear unworthy of much concern, like early use of 128 bit AES for
session encryption. Clearly of interest if a meeting concerns national
security or other public policy matters, or important organization or
personal privacy matters. Most personal/family communications probably
do not involve such things.

Running it in a VM might improve security, although one responder
mentioned sound pass-through as an issue, and setup, at best, would be
more work. Dedicated hardware, if you have it probably would be a better
choice for isolation.

An alternative would be to install Debian and Zoom on a USB key or
drive. I would expect USB2 to be adequate, although maybe a bit sluggish
at times.

You also could put the machine on a guest WiFi to isolate it from other
machines.

As with all software, keep it up to date. With Zoom's present rate of
update, that could be as often as before every use. All the other users
also should keep theirs up to date.

Zoom users, of course, should be aware (a) that free subscriptions are
not encrypted end-to-end and (b) Zoom cooperates with law enforcement
agencies, probably meaning that they will allow interception if
presented with an appropriate warrant (in the US; other nations' laws
are different).

Cloud session storage might also be an issue, although the Debian client
session recording appears to be local when activated.

Regards,
Tom Dial

[1] Using apt install, and the absolute path, instead of dpkg, may have
helped resolve dependencies; I have seen reports to that effect.

[2] scaleFactor=2 in .config/zoomus.conf instead of default scaleFactor=1.

Don't. Zoom is not necessary to stay in touch with family. If you cannot get 
another video conferencing provider, use a phone. But do not prove to providers 
such as Zoom that you need them for your most intimate needs — it fuels their 
wrong-doing.

Also, I had the impression that this were a technical support mailing list, not 
a family therapist forum.

Looking for ideas.

my current thoughts, in order of preference:

1. Use a separate Debian alongside my daily driver, and use Only for the  
Zoom meetings


2. Sandbox? (but how can I do that?)

3. Use a different browser


[...]

Hello,

best practice is certainly using different software (Big Blue Button has  
been mentioned, Jitsi works OK for small groups, say ~10 persons, too), but  
there are cases where I am not asked to decide the software. At least, Zoom  
works on Linux whereas e.g. Skype for Business doesn't despite claiming to  
have a „Web App“?


I am also using Zoom (not by preference, see above) and thought about ways  
to isolate it for which I basically came up with a similar list to yours.  
Here is what I did so far:


* Zoom inside a VM works well here. I use Virt-Manager + KVM and
  audio works flawlessly without the need for much additional configuration.
  I only added this line to .config/pulse/daemon.conf:

flat-volumes = no

  This makes sure that opening the VM does not reset volume back to 100%
  which is dangerously loud on my sound card, see
   :)

* As a fallback solution, I setup a sandbox for chromium using firejail
  (package firejail) with a custom profile (attached for those interested).

  If you do not like the VM approach, you might consider a sandbox around
  the zoom client. Of course, it is possible to use the sandbox inside the
  VM, too. I doubt the added security of combining VM+sandbox is worth the
  added complexity, though.

Using an entirely different system is certainly an option security-wise (if  
network isolation is considered properly), but might have some additional  
practical limitations.

Problem Installing Debian

[Analis Dannen]

Greetings
This is Analis Dannen. I really want to replace my crappy windows
operating system with Debian. As a blind user, I rely on ORCA Screen
Reader to get around in Debian. Well, I have an issue. Orca will not
respond when I try to navigate the installer. It simply says the name
of the program and that is about it. Here is what I have tried.
Enabling the root account through the terminal
After root is enabled, logging out of the live session then logging back in
Logging into the root account only to find that ORCA does not seem to be there
I desperately need your help. Please respond to this Email as soon as
possible. Thank you very much!

following message every time that open Dolphin:

KDE run Dolphin as root?

[Default User]

Hi, all.

As an experiment, I just installed Debian 10.4 Stable on a spare drive, and
installed kde on it.

I have not tried kde in many years, so am not really familiar with it.
Perhaps I am overlooking something obvious, but I can not seem to run
Dolphin or Konqueror as root.

Searching online, I was astounded to see many references to this problem,
saying that this is not a bug, but a feature - that kde developers are
deliberately working to prevent users from using some programs, including
Dolphin as root, as a "security measure".

So, can the current version of Dolphin in Debian Stable be run as root
(without re-compiling, etc)?

And, if not, how (and why) would anyone use kde at all?

Really? Just get on with communicating with your family. That's a bit

Salut,

Bonsoir,

J'ai eu, je pense, le même problème avec une Quickcam messenger. Aucune 
détection par cheese alors qu'elle est bien vue par lsusb. En fait elle 
nécessite v4l version 1 alors que les noyaux utilisent la version 2 par 
défaut et on ne peut pas le changer après lancement de cheese. La 
solution, mais je n'ai plus la ligne de commande sous la main, c'est de 
lancer cheese en ligne de commande avec le bon paramètre pour utiliser 
l'ancienne version de v4l (v4l1). Peut-être aussi essayer d'installer et 
utiliser dov4l, il y a un paquet, qui permet d'interroger et de définir 
les paramètres des périphériques video4linux, comme une webcam donc.


Voir ici

https://doc.ubuntu-fr.org/webcam

et là

https://doc.ubuntu-fr.org/v4l1

En fait tout est dans le second lien, je viens d'essayer

commande :

sh -c 'LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so 
/usr/bin/cheese "$@"'


Et ça fonctionne...

Look into Big Blue Button and see if you can get your family to try

bigbluebutton is interesting. Thanks for the thought.

Many family members use Zoom, and like me, are past seven decades.
Several of the younger set use Zoom also.

It works in the browser without installing anything, at least in Google

However, it does require you to register, and then they spam you with

If you're used to the common keystrokes for copy/cut/paste/undo of

that certain commands won't mirror the tutorial exactly but as far as I
use Emacs, it is a benefit.  I do disable CUA mode when I use Org mode
as it uses the Shift+arrow keys for special functions rather than
selecting text.

Defining "used" in terms which an algorithm could detect would be
difficult here (Windows tries, or used to, but in my experience almost
always gets it wrong), but you might find some benefit from deborphan,
in the package of the same name. It basically reports the names of
installed packages which are not depended on by anything else.

On its face this wouldn't be useful, since nearly everything you've
explicitly installed will usually qualify; what makes it useful is that
it can (and, by default, does) limit its search to only specific
sections of the Debian package archive, such as libs, oldlibs, and so
forth.

Since 'apt-get autoremove' already detects and removes packages which
were installed only as dependencies and aren't depended on anymore, this
is useful only for packages which got explicitly installed once upon a
time and may have been forgotten about. I don't see such very often
anymore, but when I first installed deborphan and tried it out, I found
a surprising number of them.

Nowadays, my regular upgrade-against-testing routine - carried out at
least weekly, if not daily - consists of the following (with adjustments
to account for undesired installations, removals, bugs as reported by
apt-listbugs, et cetera):

$ apt-get update
$ apt-get dist-upgrade
$ apt-get autoremove
$ apt-get remove $(deborphan)

And if the deborphan step finds anything, I go back to the autoremove
step, and repeat until neither of them has found anything.

When I first started with deborphan, it took me somewhere between three
and six repetitions of that pair of commands before I got to that point.
Now, I can't even remember the last time deborphan found anything,
because the system is already clean in this regard - but I still keep it
up, just to make sure that doesn't change.

What I originally wanted was based on the false assumption that there
are "system packages" and "user packages" in Debian, which turned
out not to be the case.

The assumption was also formed partly after the FreeBSD experience, and
partly under the impression of Pamac, Mint Software Manager, App Store,
Google Play and other "software centers" which offer productivity
software install/uninstall in convenient form.

The ability to identify packages that have not been used recently and
remove them, would be useful too.

In a way, the subject covers most of it: " Using a USB hub with 3 computers, 1

I don't know much about USB hubs, I guess all of the ports are two way.

To clarify, if needed, I'd like to buy a 5 (or more) port USB (3.0) hub to
connect 3 PCs, 1 printer, and 1 external drive such that I can print or backup
from any of the 3 pcs.

I suppose there are two questions:

1.  Should I expect any problem "hardware wise"?

2. I suppose I have to consider the mounting of the partitions on the
drives, I suppose it would be a bad idea to have the same partition (or even
drive) mounted on more than one pc at the same time?

(And I guess I'd have to avoid printing from two computers at the same time.)

Another thing to check (which may or may not apply in this particular
instance) is any special TMP/TEMP/TMPDIR/TEMPDIR environment variable
handling in the host environment.  On my systems I use pam_tmpdir, which
creates a user-specific temporary directory (/tmp/user/${UID}) and then
sets the TMP/TEMP/TMPDIR/TEMPDIR environment variables to that path.

When I chroot into an environment, I must take care to either ensure
those variables are unset inside the chroot or to create the necessary
directory structure with matching ownership and permissions.

Another solution is to bind mount /tmp from the host into the chroot.

Eh, yes, of course. Was ahead in my thoughts and mixed both facts
together.

To be completely clear, it's the world-write bit that allows _apt to
create files/subdirectories there.  The sticky bit prevents other users
from removing or renaming said files/subdirectories while _apt is
using them.

The short answer to this thread is that unfortunately Debian is

As has been explained, it's not so simple, because *your* focus is
solely on the last apt command that you typed, whereas the package
management system is concerned with the whole system. Apt deals with
the system as a current state, and not as a chance sequence of
commands in reaching that state which must be reversible and
replayable, back and forth.

When you install some packages and change your mind, just copy and
paste the line from /var/log/apt/history.log, replacing install with
remove (or purge). Sophisticated?


Doesn't that fail to address the exact Recommends-related scenario which
was his original complaint?


Say A and B both recommend C, and no other relevant packages do. Then:

$ apt-get install --no-install-recommends A
$ apt-get install B
$ apt-get purge B
$ apt-get autoremove

As I recall and understand it, his original complaint is that this will
then leave C installed, even though the context for the permission for
it to be installed (the installation of B) no longer applies.

(Similarly if you install A after installing B but before the
autoremove.)

By contrast,

$ apt-get install B
$ apt-get purge B
$ apt-get autoremove
$ apt-get install --no-install-recommends A

will leave C not installed.




Thank You! You perfectly understood me and put it into clear words.



He appears to argue (if not all that clearly) that the package manager
should be tracking "install Recommends?" status on a per-package basis
(i.e., probably in /var/lib/dpkg/status), such that only packages for
which that flag is true will be considered as preventing a Recommended
package from being autoremoved, even when Recommends are configured to
be important. This would then let those two scenarios produce the same
result, which could be argued to be valuable for "least surprise"
consistency reasons.

Given the existence of the ability to configure Suggests as important,
presumably an analogous flag would then need to be tracked per-package
for Suggests as well.

Structurally this doesn't even seem too difficult to design, at a naive
outsider's glance, but how practical it would be to implement - both in
terms of code, and in terms of the data that would have to be tracked
and stored, as well as in terms of implementing both on top of the
existing stored data which does not track this - may be quite another
story.

  > It gets trickier again when you start to consider more complex
scenarios, such as what happens when you change the "install
Recommends?" status for an installed-as-Recommends package later on.

When you install A with --no-install-recommends, C would clearly get
that status set to "false".

But when you install B without that switch, should C's "install
Recommends?" status change to "true"?

If the answer is yes, then the problem he was complaining about returns.

But if the answer is no, then if you later remove A, C is now in a
different status from what you'd have gotten if you installed B (and its
Recommends) without having ever installed A in the first place.

I don't see as simple or straightforward a way to design around that
problem. At that point, I think you would indeed have to start tracking
the installation history in tree fashion, and I don't even know what the
data structures or the necessary stored data for handling that elegantly
or cleanly would need to look like.



Because of this more complex scenario I suspected that not simply a flag 
might suffice and therefore suggested that a tracking list would be 
needed for registering exactly by WHICH other package a certain package 
became recommended and drawn in. This list would get longer if more than 
one package would have asked for the recommended, certain package, and 
if this certain package specific list would result empty again then this 
would flag it for allowed autoremoval. Of course the certain package 
should not be an essential package like installed during the intial 
Debian installation, but this requirement is what the current apt is 
already considering for all packages anyway.


After your post nicely confirmed that my idea was perfectly understood, 
I will leave it here in the thread as it is. In the near future I will 
organize my words, probably copying some of the statements from this 
thread, and send it as a feature request to the apt developers. I think 
there is not more which we can do as simple users at this point.


Best wishes, Marco!

Bonjour,

Je l'avais bien désinstallé ainsi.

D'après ce que je comprends:
- Refind n'est qu'un Boot Manager (une interface de choix du système

- Grub assure les 2 fonctions de Boot MAnager et Boot Loader

Problème ports USB

[mahashakti89]

Bonjour
Problème ports USB suite à un crash. Plus de clavier, ni de souris... 
Habituellement du Logitech sans fil. J'ai branché un clavier filaire et après 
maints essais j'ai trouvé un seul port Usb fonctionnel.
 Ce qui m'a permis de pouvoir accéder à l'uefi. Tous les ports reconnus et 
activités. Mais toujours un seul port Usb disponible au final que ce soit sous 
Debian, Ubuntu, etc...

 J'ai essayé pas mal de choses (BIOS, mémoire) mais rien de nouveau.
Je suis preneur de toute idée...
Cordialement

/tmp (and /var/tmp/) should have the following permissions and rights:

 root:root 1777/drwxrwxrwt

apt runs its I/O processes as a different user "_apt" and if /tmp does
not have the sticky bit set, then it cannot create any files there,
causing the error.

Buster install using debootstrap.

[Marc Shapiro]

I have just installed Buster on a spare set of partitions using 
debootstrap, as documented in:


    Appendix D.3 of the Installation Guide.


When I got to configuring networking, I just copied 
/etc/networking/interfaces, /etc/hosts, /etc/hostname, and 
/etc/resolv.conf from my Stretch partitions/directories to the Buster 
partitions/directories.


I also copied /etc/apt/sources.list and /etc/fstab from Stretch to 
Buster, editing them as needed.


I have chrooted into Buster and everything looks good.  I can run 'apt 
show' and 'dpkg -l' (I like the way the new dpkg lets you scroll through 
the list instead of just running to the end.)  What I can not do is 'apt 
update'.  When I try that, I get the following output:

I read the manpage for apt-secure and I am assuming that I am missing 
the GPG keys, but I did not see anything about this in the Installation 
Guide.  I'm sure that I missed something, somewhere, but I don't know what.


I also don't understand why it says that it could not create temporary 
files in /tmp.  I
