The 'su' utility has nothing to do with the 'sudo' utility and they are
controled separately.

The 'su do ('sudo')' utility is controled by the file '/etc/sudoers' or
by any file placed in the directory '/etc/sudoers.d'.
So to grand full access to a specific user in the sudoers file you would
have something like:

' ALL=(ALL) ALL'


Where  is to be substituted by the desired user.


The 'substitute user ('su')' utility is used in conbination with 'pam'
and is controled by the file '/etc/pam.d/su'.
Unless you know what you are doing, it is strongly suggested to use the
'--login' option to get a logging shell like so:

'su --login'

La orden que has definido como atajo de teclado no se corresponde con 
lo que debería ejecutar XF86Sleep, es decir, tú has configurado el 
botón para que ejecute «xfce4-session-logout», que te saca el menú de 
opciones de cierre de sesión, pero XF86Sleep debería ejecutar 
directamente el procedimiento de entrada en suspensión del equipo (ojo, 
suspender «--suspend» no es apagar «--shutdown»).

Si no te ejecuta nada podría ser por dos motivos:

1. El atajo invoca la instrucción correcta pero la orden falla
2. El atajo no invoca la orden porque ya está asignada u otro proceso 
la tiene «secuestrada»

Yo probaría lo siguiente:

Para descartar 1., asigna la orden a otra tecla o combo para ver si 
funciona correctamente y descartas un fallo en la ejecución de la 
instrucción.

Para descartar 2., prueba a detener los procesos de salvapantallas o de 
configuración de energía que puedan estar estorbando.

Recuerda que los atajos los puedes configurar desde dos sitios:

Menú → Configuración → teclado
Menú → Gestor de ventanas → teclado

It works like a charm!

I ran the script on each pdf, your program did its magic on each in
place, and a diff showed no difference!

Thank you so much, David! Another reason for people to pick up Raku programming.

Re: ps2pdf: why differences in different instances using unchanged PS source file

[David Warring]

Hi Tom,
Yes quite right. As The Wanderer points out the CreationDate and ModDate
differ, as do the uuid in the Catalog Metadatas and the trailer ID.

I've found that deleting the optional dates from the Info dictionary, the
Metadata entry from the Catalog and resetting the ID does seem to be enough
to make output PDFs identical. In the simple case at least.

This gist https://gist.github.com/dwarring/1e4e056d84d6fe125262bba1da1f58fb
does
this using the Raku PDF module. Usage is:

p2s2pdf-strip.raku in.pdf [out.pdf] # post-process ps2pdf output

I've used the lower level PDF::Reader interface, which doesn't often get
used directly. But in this case, we also need to bypass Raku PDF also
attempting to update the same fields. The PDF also needs to be rewritten,
rather than being incrementally updated.

Hope that works in this case.

Regards
David Warring

Wifi sélection du site ayant la meilleure réception

[MERLIN Philippe]

Bonjour,
Mon système d'exploiation est une  Debian Sid AMD64 et j'utilise Wicd pour me 
connecter automatiquement à un site cela marche très bien, cependant quand il 
y a un répéteur Wifi il choisit souvent le répéteur Wifi qui a une puissance de 
réception plus faible étant plus éloignée de l'ordinateur que le maître. Y a 
t'il un moyen pour que la sélection se fasse en cas d'égalité sur l'ID ayant 
la puissance de réception la plus  élevée.
J'ai cherché sur le net une solution sans succès.
Merci à l'avance pour vos suggestions.

Tecla rápida XF86Sleep en teclado

[Josu Lazkano]

Buenas,

He adquirido un nuevo teclado que dispone de algunas teclas rápidas, he
podido configurar todos excepto el de apagado.

Utilizo XFCE y desde la configuración del teclado se pueden asignar los
lanzadores para cada botón.

El problema lo tengo con el botón de apagado, no hay forma que se ejecute,
he probado a lanzar cualquier aplicación, pero es como si hubiera otro
proceso capturando ese botón.

La configuración está de esta forma:

[image: image.png]

El botón se llama XF86Sleep, ¿alguien sabe como puedo hacer funcionar ese
botón?

Gracias por todo y un saludo.

Réponse courte: non avec du wifi5 (a-c-n).

La solution passe par du wifi6 (ax) et du mesh. Cette nouvelle norme
wifi est bluffante. Cela demande du nouveau matériel mais ça en vaut
vraiment le coup.

For future requests, you can get English messages by overriding the LANG
(or LC_ALL) variable.

LC_ALL=C apt-get whatever

or, if you're in a csh/tcsh shell, or if you're using sudo:

env LC_ALL=C apt-get whatever

This is better than translating yourself, because the exact wording of the
"C" locale messages is extremely well known, and will convey information
to those reading your mail.  In particular, there is a big difference
between the messages "Permission denied" (errno 13) and "Operation not
permitted" (errno 1).

Joe,

Thanks for the GRANT hint and the reminder to configure users in a
terminal as root.
No phpmyadmin in use here, I'm using the terminal for everything, same
as in my $realjob.

Appreciate the reply, I'll try this new info from you and Deloptes and

Deloptes,

I will try the login method and 'grant' as you suggest above.
The database is on the same host, I should have mentioned that, and I
see now that the setup for MariaDB has changed from when I last
installed a mediawiki instance under Debian.

Thanks for the info!

You don't even need the CREATE USER.

You can GRANT  TO 'fred'@'localhost' IDENTIFIED BY 'yyy'
which will create user and privileges at the same time.

Remember that modern versions of MySQL/MariaDB will not allow logging
in as root unless you are already logged in to the terminal as operating
system root. This means that phpmyadmin, if you use it, cannot login to
the database root account, and you need a differently-named account with
all privileges, including GRANT.

Bug#977358: release-notes: document how to make the rescue mode usable if no root password is set (buster)

[Andrei POPESCU]

Package: release-notes
X-Debbugs-CC: debian-user@lists.debian.org

Dear Release Notes Maintainers,

Some text based on below would make sense for the Release Notes for 
buster. If agreed I'll try to come up with a wording.

A web search found #802211[1].

Short version:

For systemd >= 240 (buster[2]) run as root

systemctl edit rescue.service

and add:

[Service]
Environment=SYSTEMD_SULOGIN_FORCE=1

(see /usr/share/doc/systemd/ENVIRONMENT.md.gz)


The 'rescue.service' is started by systemd in case it detects 'single' 
on the kernel command line (see systemd(1)).

You might want to do the same for 'emergency.service' as well (or 
instead), since this service is started *automatically* in case of 
certain errors (see systemd.special(7)) or if you add 'emergency' to the 
kernel command line (e.g. if you can't fix your system via the 'rescue' 
service).


An untested patch to the Debian Installer exists to add both snippets if 
the user chooses to leave the root password blank.

Comment associer les identifiants 802.1X aux baux DHCP ?

[Olivier]

Bonjour,

Dans un environnement WiFi où les utilisateurs utilisent leurs propres
appareils (PC portables, smartphones avec un total de 4 appareils maximum),
comment associer l'identifiant 802.1X à un bail DHCP ?

Idéalement, j'aimerai pouvoir implémenter une règle déterministe du type:
"si un appareil s'identifie avec l'identifiant 802.1X Foo, je lui affecte
une adresse dans le pool 192.168.1.150-154,
s'il s'identifie avec l'identifiant 802.1X Bar, je lui affecte une adresse
dans le pool 192.168.1.155-159, etc ..."

À défaut, un log consignant les 2 infos (adresse IP et identifiant 802.1X)
dans un même support (fichier ou base de données) me suffirait probablement.


J'ai jeté un coup d'oeil intéressé sur la doc du serveur DHCP intégré à
Freeradius mais :
- je n'y pas retrouvé explicitement qu'une telle association était
implémentée,
- je ne l'ai pas trouvé très détaillée ou facile à aborder.

Avez-vous déjà expérimenté ce serveur DHCP ?
Qu'en pensez-vous ?

When installed in Debian it does not have password (AFAIR). It is sufficient
to execute "mysql -u root -p" and press ENTER to log in. You then change
the password.

Regarding --skip-grant-tables I used this just last week to reset a root
password for a customer.
It seems there are two different methods depending on what version you use.

Could be that you have something on the network side? From which host do you
log in?

This is working only on localhost

Just try 
mysql -u root -p -h localhost

So
mysql -u mediawiki -p -h localhost
is not working as well?

I use following and never had issue with that

CREATE USER 'mediawiki'@'localhost' IDENTIFIED BY 'xxx';
GRANT Select ,Insert ,Update ,Delete ,Create ,Drop , Index ,Alter  ON
mediawiki.* TO 'mediawiki'@'localhost';
flush privileges;

Remember the client can access only on local host.

ok, here's what I did:
- deleted both wired connection
- created a new connection named "Wired LAN"

After reboot, NetworkManager shows up a new connection named "eno2" that uses  
eno2 interface and configured only for Ipv6.

Note that this eno2 connection does not show up in /etc/NetworkManager/system-
connections/. Only 'Wired LAN.nmconnection' is there.

This eno2 connection is removed from the list of available connection (in 
NetworkManager configuration widget) once I connect "Wired LAN" using 
NetworkManager widget.

All the best
