In the 70s friends went to this house where there was a 14 year old 
Indian

mystic.
You were all supposed to wait downstairs until you were called to 
receive

'the knowledge'.
We all left after a day but one guy stayed, after days he got really 
angry.

Stormed up the stairs, " Give me the f#@king knowledge!"
funny old times.


TBH you packed two questions into your original mail. Complaining that
most people concentrate on one is kinda... well ;-)


I don't mean to appear am complaining.
Mention of teenage Guru was attempted humour.
There were 2 question marks but really one question.
"Is there a numpty's explanation what are these PulseAudio, Alsa, Jack?"
Noticed had sound from the speakers when selecting Pulseaudio as Audio 
System but then doing that again I had no sound.

Have no idea what an Audio System is.
I have found the Ardour6 manual.
The install system looks to have put me and pulse in audio group.
Ardour manual is saying this is possibly not a good idea because only 
one person can access soundcard at a time.
There may be an explanation why second attempt had no sound output 
because something had the soundcard because of user error.

I guess you might get more help if you described what "cheat" is and where
you got it from.

There seems to be no [1] Debian package of this name, so we are left to

Not so much très chic as bijou⁰. I can edit, eg
[ -z "$Thepagecount" ] && printf '%s\n' "$1 has no pages!" ¹>&2 && return 1
to
[ -z "$Thepagecount" ] && { printf '%s\n' "$1 has no pages!" ¹>&2 ; return 1 ; }
very easily. (I think I have about 350 such constructions in ~/.bash*.)

IP por DHCP dejó de funcionar en Debian "bullseye"

[JavierDebian]

Buenas noches.

Me ha pasado algo extraño.
Debian 11 "bullseye" con kernel 5.10.0-16-amd64.
Network-manager prohibido en el sistema, lo odio porque hace lo que quiere.
Computadora que funciona desde hace 6 años con configuración de red por 
DHCP automática, configurado "a mano" por interfaces.

resolvconf corriendo como demonio.

Hace un par de días, se puso remolona para tomar dirección IP. 
Reiniciado el enrutador y el equipo un par de veces, lo achaqué a 
problemas del enrutador o del servicio provisto por mi ISP, un CISCO 
Technicolor DPC3848VE DOCSIS 3.0, empresa Flow/Personal/Fibertel Argentina.


Hoy hizo lo mismo; intenté la solución anterior y no hubo caso.
Cambié cable de conexión, sin éxito.
"¿Será la placa de red?"
Arranqué Windows desde otra partición; conexión impecable, no es ni el 
cable ni la placa ni el enrutador.

Arranco un SystemRescueCD, y toma la dirección sin problemas.
Vuelvo a Debian, no toma dirección IP.
Levanto una máquina VirtualBox en Debian que corre un Win7 con la red en 
modo puente... toma la dirección sin inconvenientes


Configuro la red en forma manual, con IP fija y todo a mano
Funciona sin inconvenientes.

Vuelvo atrás, a configurar por DHCP automático; no funciona, pero sólo 
en Debian 11.
Cambio a kernel 5.10.0-13, no sea que el kernel nuevo tenga algún 
problema, aún siendo "stable"; sigue sin funcionar.


Ahora estoy en modo IP estático, funcionando sin problemas... salvo que 
no puedo volver a DHCP dinámico, porque no funciona.


Para usar la máquina, no me afecta, pero... NO ME GUSTA QUE EL SISTEMA 
HAGA COSAS QUE NO DEBERÍA HACER, O NO HAGA LO QUE SÍ.


Seguiré investigando.

Si a alguno le pasó algo así, escucho sugerencias.

Gracias.

Maybe not what you want but I've used a rpi4 with hdmi to usb capture to

I assume the EFI partition was not partition 1 and thus survived.
But probably the GRUB software in that EFI partition wanted to jump onto
software which was in partition 1. So overwriting partition 1 by the ISO
left that GRUB software clueless.

DD mode, as Rufus itself told me to use that mode in case of problems

Maybe the GRUB software on /dev/sdb was for the wrong firmware ?

Indeed you should have copied it to /dev/sdb.

I stumbled over the line in your initial report

and got suspicious enough to ask

Maybe you would have detected a difference in behavior which would have
proved that your ISO was not put to the proper place on the stick.
Partition 1 in a Debian installation ISO begins at block 0 and thus at
the same block where the overall device begins. So with the ISO at the
right place, there should be no difference ... normally ... :))

I guess you had partition 1 starting at non-0 and some GRUB debris on
/dev/sdb before the start of /dev/sdb1. That debris would then have
given you the grub> prompt.


> Now i tried the same usb key on another laptop, Toshiba, and it

Maybe the GRUB software on /dev/sdb was for the wrong firmware ?
Legacy BIOS vs. EFI.
Both firmware types begin the very first stage of booting non-firmware
at different starting points (MBR x86 code vs. EFI partition with FAT
filesystem and boot programs with predefined names).

It fails to build because of incompatibility with new ffmpeg:

Certainly sounds like a temporary problem.  According to

 gtk3-nocsd LD_PRELOADs a small library to disable the client
 side decorations (CSD) of Gtk+ 3.

 Since Gtk+ 3.10, its developers added a so-called header bar or custom
 title bar. With this and the client-side decoration, the original title
 bar and window border provided by the window manager are disabled by
 Gtk+. This makes all Gtk+ 3 programs look like alike, but have different
 handling from other windows on non-GNOME desktops. Even worse, this may
 break some window manager or compositors.

 Unfortunately, there is no reliable way of turning off CSDs in Gtk+
 directly. This library makes this possible.

I just googled 'usb null modem cable' and got this:
https://ftdichip.com/products/usb-nmc-2-5m/
which is available from lots of electronics suppliers, e.g.

I cannot call it "ready-made", but there's something similar - [1] which
may solve your problems.
It does not deal with serial per se, but achieves much more.
Some assembly is required though.

That will work, I have similar setup back in the day.
The main problems of such setup are:

- overcomplicated setup of GRUB's USB stack.

I.e. forget about seeing GRUB's menu.

- unless you're using self-built Linux kernel - forget about seeing
  those boot messages.

Because to convince the kernel to use that "console=ttyUSB0" argument
you'll need to load an appropriate kernel module first.
Such setup is good for saving you from the descent to the cellar in the
case of occasional network misconfiguration, but that's about only
problem it's good for.



Hardware platforms with built-in UART are easier in this regard, but -
it's very rare to have UART on a consumer-grade x86 motherboard.

> is it possible to run a console on a USB port of a headless server?

Yes and no.

The T20 doesn't seem to have iDRAC (IPMI) support, so BIOS/UEFI
is not available through a serial console.

The first time you have an opportunity for a serial console is in GRUB;
then again you have an opportunity for the kernel output; then finally
you can have a login on a serial terminal.

You will need a USB to RS232 serial adapter, and then an appropriate
cable to talk to your terminal device. The other end can also be a USB
to RS232 serial adapter. In between you might have a 9 pin
serial cable or a specially wired RJ45 (looks like ethernet)
cable.

The name of the device should be something like /dev/ttyS0
(S1,S2,S3...) or can be /dev/ttyUSB0. USB ports can be renumbered on
each boot, but as long as there is only one serial adapter connected,
it should always be recognized as /dev/ttyUSB0

Pedantic note: your error checking can fail.  If the printf fails for
some reason (e.g. because stderr has been closed, or is redirected to
a file on a file system that's full), the return won't execute.

It's best just to use "if" in the normal way:

  if [ -z "$1" ]; then
printf ...
return 1
  fi

That way, the return will still be executed even if the printf fails.

If you *insist* on using && because you think it's tres chic or something,
then you need to use a command group:

  [ -z "$1" ] && {
printf ...
return 1
  }

But this is not the recommended practice.

Bonjour,

En complément :
- si ton serveur est accessible depuis Internet : le mettre dans un reseau
dédié (DMZ) et raccordé à ta box.
- et par dessus tout : mettre à jour ton serveur web très régulièrement.

Si tu es un peu paranoïaque :
- ajouter le mod_security sur ton serveur web (si c'est du apache).
- ajouter une sonde de détection d'intrusion sur ton réseau de type
suricata.

Do you have access to the MATE Control Center, through the applications

If so, in there, is the Hardware -> Sound settings configurator

Also, in System -> Preferences -> Hardware -> Sound

Whilst this is on a UbuntuMATE system, I expect that you should, if you 
are using the MATE desktop environment, have access the same way, to the

That is an AppImage, so it will certainly work - if you still want to use

After days of waiting the imparted knowledge consisted of your

And why audacity isn't in the Bookworm repo... perhaps it's temporary?

It's packaged for Debian, so perhaps OP's life would be a tad
easier doing "apt install audacity"?

This is a Debian mailing list, after all :)

Re : Re: Gestion du ventilateur sur un PC portable.

[benoit]

Bonjour Bernard,

Merci pour votre réponse.
Si ça ne fonctionne pas avec ça, c'est que le problème est matériel ou qu'un 
truc m'a échappé dans le bios.

Apprendre à sécuriser un réseau domestique

[benoit]

Bonjour à toutes et tous,

Désolé pour cette demande un peu HS, mais je ne saurais pas l'énoncer à un 
moteur de recherche. Seul un humain peut me guider vers les apprentissages qui 
me seront utiles.

Je recherche un tuto (par écrit pas en vidéo) au terme duquel je serai capable 
de sécuriser un réseau avec un niveau de sécurité domestique.

Genre, mon réseau n’a aucun intérêt, mais j’ai pas envie que ce soit une 
passoire et que ma passerelle (avec son petit serveur web perso) soit utilisée 
pour mener une attaque sur un autre réseau. Mon réseau étant domestique, n’est 
pas vulnérable à des attaques de l’intérieur, il n’y a personne de malveillant 
à l’intérieur. Donc cet aspect de la sécurité des réseaux d’entreprise ne me 
concerne pas. Pas de contrôle parental a mettre en place non plus.

Et aussi, comment sécuriser mon ordinateur portable quand je suis à l'extérieur 
sur un wifi ou que j'utilise la 4G.

Je me suis acheté ce livre espérant en apprendre davantage, mais il est trop 
verbeux et je me suis découragé.

https://www.editions-eni.fr/livre/securite-informatique-ethical-hacking-apprendre-l-attaque-pour-mieux-se-defendre-6e-edition-9782409033667

Je voudrais un tuto qui explique en quelques lignes (et pas 50 pages) avant de 
montrer les commandes à taper.

Tous est sous debian, ça ne m’intéresse pas de savoir sécuriser un Windows ou 
un mac.
Si j’ai envie d’en savoir plus sur une attaque j’irai chercher l’info dans ce 
livre.

Si je recherche moi même, n'y connaissant rien en sécurité, je risque de m'y 
perdre ou de passer à coté de notions importantes...

Si vous pouviez me guider vers les compétences nécessaire

Merci d’avance

This issue has been present for a long time unfortunately.

There is a workaround, you can use a URL query parameter instead:
