Relative physical positions of motherboard components are for the motherboard's
entire life.

Time is an implicit element of every race.

Time can't change motherboard components' relative physical positions.

Hi debian

Why can I not fint "en_DK.UTF-8 UTF-8" when I install a normal os from

I know that I can set it after the installation, but it is not the same!!

Thank you and all others.  It turns out that getting the
autoflush to work in perl is on a par with falling off of a log
for ease of execution.

There is a perl variable called $| which, when set to a
non-0 value can cause an immediate flush of a buffer but perl
experts recommend you not do it that way.  It's even clearer.

At the beginning of your perl program you add a line

use IO::Handle;

That is like an include in C so the perl language handler will
know what you mean when you add the next line right after you
write to your file:

FH->autoflush(1);

FH is just my example name for the open file handle.  Perl custom
is to use all caps for the name of the file descriptor so FH or
LOGDATA refers to that file and flushes that buffer.

In this case, it is an endless loop so the buffer gets
flushed after every new write, but that's how you make it happen.

Re: Discussion? New names of betwork devices

I suppose I should add this. In datacenters of a certain size, when the
network cabling leaves control of the OS administrators (yes, even the
Wintel admins), network admins aren't there to make your life easier. You
do it yourself.
I encountered the same issue with SAN admins a bit later over fiber cabling
to my servers. If the OS adds complication you deal with it, even if you
didn't have to before. You can argue that admins should have been
explicitly configuring NICs with salt, cobbler, etc. We did.

It's interesting how this topic is so often resurrected. The first time we
upgraded a RedHat server and the network interfaces were renamed, our
supervisor was.angered :-)
The issue is the order of enumeration of devices on a PCI bus. Even
identical models of NIC at the same level of firmware will become ready in
non-uniform ways. Temperature plays a role, etc. If the systemd designers
(same as the udev guys, right?) made a mistake here, perhaps it was
overreach.

accesibilidad con configuración standard y usuario root

[Fran Torres]

Buenas,

He reinstalado debian9 en mi HP Pabilion 250G2 y dejado la
configuración que viene por defecto con el sistema, a excepción de los
ficheros:
/etc/default/speech-dispatcher y /etc/speech-dispatcher/speed.conf
Bmbos ficheros, se les han modificado (respectivamente) las siguientes líneas:

RUN=yes (/etc/default/speech-dispatcher)
output_mode="libao" (etc/speech-dispatcher/speed.conf
  Tengo sonido sin problemas con el usuario root y con el normal pero,
en el normal se activa el lector de pantallas sin problemas, mientras
que con root ocurre lo siguiente:
1. El lector de pantallas no se activa.
2. Si en el diálogo ejecutar aplicación de mate escribimos: orca
--setup, se abre el diálogo de preferencias de orca pero, no habla.
3. Dentro del diálogo, si vamos al apartado configuracióon de voz,
encontramos que los siguientes parámetros: sintetizador, sistema de
voz, y relacionados están deshabilitados.
Cuando en sintetizador debería aparecer: por defecto del sistema,
espeak, espeak-ng, etc. EN sistema de voz, debería aparecer:
speech-dispatcher.
  E incluso, el propio orca debería arrancar hablando. A alguien se le
ocurreo como hacerlo sin tener que recurrir a la fuerza bruta, que es
como está documentado en debian, lo cual sospecho que me altera otros
comportamientos, de firefox por ejemplo?

Fran.
PD: la línea: autospaun=yes de /Etc/pulse/client.conf está tanto en
interfaz gráfica como en la consola igual, y en consola speakup
funciona sin problemas, orca funciona sin problemas en interfaz
gráfica con user normal. Pero, no funciona con root. Quiero que
funcione con este último, para tener una accesibilidad completa.
Ideas?

No. Changes in the activation order or the number of devices do not
matter. The naming scheme is based on what bus the devices are on and
what position on that bus they hold[1]. Once a name is assigned, unless
you plug the card into a different slot, you will get the same name
(note that this may not apply on hotplug architectures that don't assume
fixed slot positions, like USB).

It is the *old* way that lead to unpredictable renames unless you
implemented udev rules to hardcode names to e.g. MAC addresses.

Is it any worse than expecting them to write a udev rule?

In the end it is a hard problem to solve because the Linux kernel does
dynamic enumeration of devices, so you either need a deterministic
algorithm to assign a name (ask the firmware) or a userspace workaround
in identifying the device (e.g. using udev rules, or using UUIDs in
/etc/fstab, etc).

Re: Discussion? New names of betwork devices

[Hans]

Hi folks, 

interesting thing, I found this little article in internet:

https://www.freedesktop.org/wiki/Software/systemd/
PredictableNetworkInterfaceNames/

So, it looks like, since systemd v197, all devicenames are now predictable by 
udev.

If so (just an idea) packagers or developers may add a routine for the 
installation, which may ask for the actual names of the devices in the system 
and add them automatically into the configuration of the installing 
application.

As these (the devicenames) will never change, also non experienced users have 
to quarrel with the devicenames any more.

Just an idea, I do not know, how difficult it is, to write and add such a 
routine into the installer as a script (I am no coder). 

However, if one gets such a thing working, it can be used for EVERY package. 
My idea is, to add a variable or a special keyword into the configuration file, 
which will be automatically exchanged with the correct devicename.

Sorry, I can not do this myself (I am no coder, did I tell you?), just sharing 
my ideas. Maybe someone think my ideas usefull. If not - just ignore them.

In this case I apologize for all the noise.

Have a nice weekend!

Best

Hans

Mailvelope in firefox: "GnuPG is not available"

[Georgios]

Hi!

I'm running debian testing and I'm trying to use mailvelope with Firefox
in order to encrypt/sign my emails. I plan to use it with my yubikey.

I'm getting "GnuPG is not available". Any ideas how to solve it?

One solution i could try is downloading the packages from
https://www.gnupg.org/download/index.html and installing them.
The problem is that this option means i must manual update them.

I already tried putting a file called gpgmejson.json inside
/home/gpdsbe/.mozilla/native-messaging-hosts/

gpgmejson.json
{
"name": "gpgmejson",
"description": "Integration with GnuPG",
"path": "/usr/bin/gpgme-json",
"type": "stdio",
"allowed_extensions": ["jid1-AQqSMBYb0a8ADg@jetpack"]
}


I'm thinking that the problem is that there is no gpgme-json.
Any ideas what package i should install?

Or any other solution?


Thanks in advance.

Hi,

I am trying to build a custom ISO from this guide:

But the ISO fails to boot, with a message that it can't find the init system.

Then trying to understand: https://wiki.debian.org/DebianCustomCD but the  
whole page is bit overkill for what I want to do.


Do you know any simple, minimalist, up-to-date guide to create a custom  
minimal live ISO?


I do not know of any guide (btw. thanks for sharing the link, I think it  
will also be useful for me in the future...).


Might be too trivial a question, but: If the message is about a missing init  
system, have you cheked some options around that? If I understand the guide  
correctly, it recommends using


apt-get update && \
apt-get install --no-install-recommends \
linux-image-686 \
live-boot \
systemd-sysv

You might try using regular sysvinit? In my scripts I use
package `live-config-systemd` (which is not sysvinit but still another  
package as recommended in the guide). As a debugging measure it might also  
be interesting to omit the `--no-install-recommends` because the missing  
package might be reommended by another and it would be easy if the fix is  
just installing some more packages (one can find out which exactly are  
needed later).


Also, it is fine if you want to know all the details and create the live-iso  
with the guide, but other more automated approaches exist, e.g. I used  
`remastersys` (now seems to be continued as Linux Respin?  
http://www.linuxrespin.org/) in the past which most often produced good  
results (except images were sometimes too large but that was my fault of  
wanting to include too much software).


In case you try a remastersys-like approach and it fails for some reason, I  
have some modified version of (the original) remastersys which continues to  
work to today with systemd and new kernels, although I have not tried it with  
Debian Sid yet and my automation still fails to setup the desired keyboard  
layout and timezone for the resulting live system :)



I want some network audit tools, emacs-nox, zfs-fuse  etc with a sid ISO.


Definitely doable. If you want to run it on a live CD/DVD you need to follow  
your guide or remastersys or such. If it later runs on an USB pendrive, you  
could also consider just "installing" Debian to the drive and see how far  
you can get with making the essential parts read-only afterwards? This would  
enable you to upgrade the system later (which is good for everyhting network- 
connected?)


Just a collection of thoughts, nothing precise at the moment :(

Reading the OP's problem, I wonder how you're meant to detect
"any whiff of a problem". All we know is that the maximum rate
*might* be 30 lines per second, but is that a guess? Are we
already losing the odd line? How would we replicate test runs?

Probably not, at 30 lps, but in principal I would say that
this is a sticking plaster while you write your better method.

The times that you can't connect are probably due to the
configuration of the network you are connecting to, not anything
under your control.

One easy and cheap workaround would be to add a second wifi interface to
the laptop via a USB interface -- find one that's compatible
with hostapd, and run that. You'll get a private wifi network
for your laptop and your iPad.

What "if"? The ATX is on the left when looking at the rear from the rear with
the slot openings facing up. ghe wanted a frame of reference. I gave the ATX
position, CPU position and PS/2 port position as usual "left" references, and
last PCI slot as "right" reference. A BTX is to an ATX oppositely situated
adjacent to the last (if any) slot.

I guess you would need to use (1)

It is unclear to me if you have one internal network (network behind
your laptop) or if both the Ipad and the laptop are connected to the
wireless infrastructure of the guest (hotel airport ...).


The former would be your best bet here including improve security.
If the latter, you can't control the restriction put on the guest
wireless. So advertising services on a guest network might never work.

True, I could have. But I don't think it will kill interested people who 
follow after to read a 3-mail thread to see the resolution.

I second that request for the same reasons David said, also seeing
someone else's name at the start of subject lines makes it look a lot
like spam.

interesting theory, but I must disappoint you that it is not true. Usually
it is from the left to the right. It has nothing to do with the ATX, except
if it would be on the left.
Thinking is good but knowing is better!
