Ok ok! à mater !
Mais je n'ai malheureusement pas trop la main sur le serveur distant en
question.
Au pire il sera possible de configurer le fameux serveur distant pour
qu'il vienne récupérer les datas, à la place de les recevoir via FTPS...

Ce sera l'occaz, du fait, dans la foulée, que je me renseigne sur le
bridage de l'accès SSH qui permet uniquement les transferts SFTP, en
bloquant la console... il me semble que cela existe... ou qu'il n'y ai
qu'un choix de comptes actifs pour la console... à voir!

Merci pour vos précédentes réponses :)

I think you're misunderstanding the use of the word universal.
USB was designed to be a universal way of connecting "any"
peripherals to a PC (sensu lato) which acts as a unique,
controlling host for them.

It wasn't designed to duplicate networking hardware, communicating
between multiple hosts. Nor was OTG. OTG was designed to allow, for
example, what's normally a peripheral to be disconnected from the
host, be connected to a peripheral and effectively become a host
controlling it. Eg, a camera could act as a peripheral while
uploading photos to a PC, then act as a host when connected to an
inkjet to print them.

Cheers,
David.

Virt-manager no Windows

Pessoal,

Tenho um projeto de virtualização onde o cliente precisa acessar o
virt-manager que está no Debian a partir do Windows.
Se isso inviabiliza o projeto.
De um linux, consigo fazer um ssh -x IP e rodar o virt-manager remotamente.
Pelo Windows, achei alguma coisa utilizando xming, mas não consegui fazer

Alguém já fez funcionar esse cenário?

Laugh all you want at people trying to help you, but time and time
again you end up posting volumes of text here without finding a
solution because you suck at concisely describing what you want to
achieve. Everyone else fails to understand you, every time, so is
everyone just stupid, or is it that the common factor here is you?

Your first email said you wanted your machines to "communicate".
That's as specific as you got.

Dan then tried to narrow it down to one specific form of
communication by spending a lot of their time listing out everything
they could think of that you might have meant, and you replied,
"Your list pretty much covers it." Useless and frustrating.

Then Stefan tried:

> > What kind of "communicate" do you need there?

Your response?

> Essentially any :/

I don't know what kind of response you expect to that uselessly
vague comment. By doing that you force people to spend a lot of
their time trying to cover every base, and then you complain at them
when they try. It really seems like you just want to complain when
people try their best to help you, even against your best efforts.

I expect to just get a barrel of whinging back for this, but I hate
to write a totally useless email myself, so…

You mentioned you want to transfer files.

If both machines have Ethernet interfaces then (as you've already
been advised) the simplest, most reliable and most performant way
will be direct Ethernet connection, or connection via a switch. If
file transfer is your goal, no need to bother with USB.

If somehow these machines don't both have Ethernet and USB really is
the only way, then again as you've already been advised, USB
Ethernet is the way to go.

We are now leaving the realms of simplicity and performance for more
subjective lands of doing things "just because" or for the retro
computing experience. You can certainly use a pair of USB serial adaptors
and then run a null modem cable between them, then run PPP over
that. Absolutely no idea why you would want to do this rather than
run Ethernet over USB. Instead of PPP you could use more arcane
forms of serial data transfer like zmodem or kermit.

If it's just a console you want, i.e. the console output and login
prompt from one machine to appear in a serial terminal program on
the other, then you can do that over Ethernet too! See "netconsole".

For a serial console when you don't have Ethernet (or want it
separate from the Ethernet infrastructure) then again it's USB
serial dongles on both ends, a null modem cable in between, then use
a serial terminal emulator like minicom or screen on the end you
want to be the client. There are configuration details involved for
the server end to get it to send console output to this USB-serial,
and put a login prompt on it.

Ask which parts you need more info on. Please be specific. Please
don't make this harder than it needs to be!

Cheers,
Andy

You can try the NVidia driver module from backports [1] and/or run

Other than speed of the copy while the error correction verify's it 
sector by sector, why not. Both rsync and rzsz are quite capable of 
sending a file halfway around the planet with the last 17 miles on a 
barbed wire fence. And getting identical crc's in the final check.

For a circuit that was actually that dirty, I think I'd choose rzsz as 
its default packet size is 256 bytes.  If the crc of that packet fails, 
it requests a resend until it gets it right. So does rsync, but rsync's 
default packet is 64k, demanding a far cleaner path. rzsz unforch has 
several cousins 3x removed, so there is less than 100% compatibility. 
And the linux version is one of the worse compatibility violators.

it to sleep by closing the lid.  When I open the lid, the disk indicator
flashes and then stops.  The power button led remains pulsing as if it's
still asleep.  If I press the power button at this point nothing happens.

Resume from sleep seems to work fine if I put the laptop to sleep via
dbus with the lid still open and then resume by pressing the power button.

I have tried both Stretch(stable) and testing with the same issue.  I
have upgraded the BIOS to the latest(and what a chore that was).  I'm

SÍ, la Dell Latitude E6410 soporta open GL
Lo dice la misma página de Dell que tiene driver para Windows

https://www.dell.com/support/home/ar/es/arbsdt1/Drivers/DriversDetails?driverId=2W14W

Para instalarlo en Linux 
Primero fijate si cuentas con aceleración gráfica, teclea esto en una terminal:

glxinfo | grep rendering

si la respuesta es: direct rendering: Yes, entonces tienes aceleración gráfica.

SINO... puedes instalar "MESA" desde el terminal o el Sinaptics

Actualizar a OpenGL 3

2018-06-01 Thread Alejandro Jurado
Hola lista,

Alguien sabe como puedo averiguar si mi equipo soporta OpenGL 3 y si lo
hace como actualizar los drivers de OpenGL. He investigado un poco por
internet y la verdad es que no he logrado mucho.

Mi portátil es un Dell Latitude E6410 con un i5 y 4 Gb de RAM (ya tiene

Gestion simple pour l'installation / désinstallation de logiciels

2018-06-01 Thread Daniel Caillibaud
Bonjour,

Je suis en train d'installer une stretch pour qqun pas spécialement féru
d'informatique, et je trouve plus le truc que j'avais vu y'a un paquet
d'années où il suffisait de cocher pour installer et décocher pour
désinstaller, avec la même présentation que le menu de démarrage, et les
même icônes.

C'est pour fonctionner avec cinnamon.

J'ai bien trouvé gnome-packagekit et gnome-software, mais c'est pas
terrible :

1) gnome-packagekit propose tous les paquets, y'a juste le tri par catégorie
mais ils ont tous la même icone, donc parmi les 90 paquets gimp-*
bon courage pour trouver le bon (nettement plus simple en ligne de
commande, c'est gimp, mais encore faut-il se rappeler du nom, alors que le
chat avec le pinceau ça cause plus).

2) gnome-software semble pas fonctionner avec cinnamon, en tout cas sur
l'onglet "tout" j'ai un grand rectangle gris, avec le titre "Sélection de la
distribution" mais rien pour faire cette sélection. 
Et dans l'onglet "Installées" j'ai bien la liste des logiciels installés,
mais sans les catégories.

J'aurais aimé un truc avec la même présentation que le menu de démarrage,
je déplie "Graphisme" et je vois tout ce que j'ai déjà et tout ce que je
pourrais activer (ça a l'avantage de filtrer en ne conservant que les
paquets qui ajoutent une icone dans un menu, ça tombe bien c'est ceux que
ce genre d'utilisateur voulait, il cherche pas les utilitaires cli).

Apparement j'ai rêvé et ça n'a jamais existé dans debian...

Et apparemment c'est un vieux débat
https://www.reddit.com/r/debian/comments/3dl2i1/debian_needs_a_software_center/

Donc probablement que la dernière fois que j'ai vu ce truc remonte à une
ubuntu dapper (la dernière ubuntu que j'ai installé pour ce type de
public, avant de les passer aussi à debian car les upgrade ubuntu posaient
toujours plus de pbs, et j'ai jamais fait attention si ce truc existait
toujours ou pas).

Si qqun connaît qqchose d'approchant, ou un moyen de faire tourner
gnome-software avec cinnamon, je suis preneur.
(même si on est vendredi le but n'était pas de relancer le troll debian vs
ubuntu ni celui de l'utilité d'un software center, car lire "Ubuntu's
software center is horrible, we don't need that. Newbs are not the audience
Debian is aimed at." me désole)

Bon WE quand même !

Indeed, it does mean that. Exim does not admit to knowing anything about
TLS, so the remote server sees no point in going any further.

Create /etc/exim4/conf.d/main/00_my_custom_macros and in it put

  TLS_ON_CONNECT = true

To the end of /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost
add

  protocol = smtps

'update-exim4.conf' and restart the exim4 service.

No problem with suspend-to-ram.

I filed a bugreport a year ago and mentioned this also in the forums, but

Maybe you the trouble of the same reason like me. 

Runnig here debian/testing (32-Bit) , but saw it also in debian/stable.

 Maybe some day it will be fixed. Maybe not, who knows. :)

Je had vroeger een backport van de installer, maar dat is niet meer:

Wat ik zou doen, is installeren op een minder nieuwe machine, kernel
updaten, dan de disk overzetten.

Just forget anyone said "crossover cable¹". You'd have to be making a
direct connection between two museum pieces to require one, and as
you have a switch, you have absolutely no need to ever do that.
Coonect both to the switch instead.

Accessibility? Using the NIC (usually at the back), it gets inserted
permanently and then forgotten, rather than needing to be inserted
on each occasion you want connectivity. Tidier too.

Bear in mind you're using the hardware as intended: no risk of
blowing up your USB port. (Ever noticed how often flaky USB ports
are mentioned here?)

You might even find you can use wakeonlan on the desktop PCs
to save some power.

¹ If you *have* obtained one, just use it like an ordinary cable nowadays.

Cheers,
David.

There is a perceived elegance aspect.
There is also a practical aspect the only known working and 
conveniently physically accessible ports are USB.


USB-Ethernet dongles would be a lot more useful in the long term than 
USB-Serial dongles. RS-232 had a really good 40 year run, but for 
general communications it was mostly obsolete nearly 20 years ago. You 
mentioned file transfers--I can't think of any applications where
that's going to be better over a pair of USB-Serial dongles than a pair

Not obsolete at all.
Availability has nothing to do with the OS (I never use either of macOS
or Windows).

But yes, OTG rare (read: non-existing) on laptops/desktops.
They're very common on "embedded systems" which are expected to be
(occasionally) plugged into a computer.  E.g. many phones's USB port
is OTG.

What kind of "communicate" do you need there?


Essentially any ;/
In fact one of the thought experiments I was pursuing was how to do file 
copying/sharing over RS232 - even I would not actually attempt to implement.




The "way back machine" to simulate a "null modem" serial cable exists,
as you've seen, but it's rarely the best solution for nowadays's needs,


"Best" is not an invariant absolute.


since nowadays connecting two computers is something completely normal,
supported by a deluge of tools, but they all expect a "network"
connection rather than a serial cable.

In most cases those two computers also have ethernet or wifi "ports" so
you can connect them via such a network (which usually offers faster
transmission than a serial cable, lets you seamlessly multiplex several
connections, and lets you use the many tools working over the network to
connect computers).


An explicit requirement is a wired, NOT WiFi, connection.
I that seriously. My internet access is a WiFi hotspot with its WiFi 
capability disabled.




In some cases one of the two computers's USB port is an "OTG" port,
meaning that it can act either as "master" or not, in which case you can
just use a regular USB cable (and usually you then configure the OTG
side to pretend it's a network card, so it ends up looking to the
software like you've connected the two machines via an ethernet cable.
That's what I use between my BananaPi "router" and my office desktop).


I saw it and it meets most (all?) my requirements except my reading 
suggested:

  1. obsolete
  2. available only for Windows/Mac
  3. no way to determine if any of machines were equipped



If none of that are options, you can resort to using an "ethernet
dongle" on both sides and an ethernet cable between the two.


That's a 1 versus 3 items required per connection.



All of those things will typically work "out of the box" on a vanilla
Linux kernel (the usbnet drivers have been incorporated years ago).

Oh, and in case those computers are somewhat old, they may also come
with Firewire ports, and those (contrary to USB) don't have the
"slave/master" distinction so you can connect your computers this way
with a plain normal Firewire cable (and make it appear to the software,
again, as some kind of ethernet-like connection).

Here is what I have done
1. Installed Stretch (amd64) with XFCE
2. apt-get install firmware-linux nvidia-driver nvidia-settings 
nvidia-xconfig

3. run nvidia-xconfig
4. turned off screen blanking in power settings

I am quite happy to spend time troubleshooting, but don’t really know 
where to start. The blanking happens too quickly for me to be able to 
do anything at the time.


Does anyone have any thoughts?


Are you able to replace the HDMI cable? Intermittent blanking for a 
couple of seconds sounds to me like an interruption in the stream of 
data going to the display, causing the display to reset.

installer met kernel van backports

2018-06-01 Thread mj

Hoi,

Kan iemand me een tip geven of (en hoe) het mogelijk is om stretch te 
installeren, maar direct (tijdens installatie dus) met een kernel uit 
backports?


Het gaat om root-device hardware compatibilty, waarvan ik vermoed dat de 
kernel uit backuports die wèl heeft, en de normale stretch kernel nog niet.


Ik zou natuurlijk ook een tijdelijk ander root device kunnen gebruiken, 
dan kernel updaten, en dan root device aanpassen. Maar vraag me af of 
bovenstaande oplossing ook (eenvoudig) mogelijk is..?


Specifiek: het gaat om een server met intel vroc / vmd ssd nvme devices, 
waarop ik dus debian root raid wil installeren.

FWIW these days, most devices are capable of doing the crossover thing
automatically [1], so you can just use a straight cable. From personal
experience, I haven't needed a crossover cable the last ten years (and
I do muck around with oldish hardware).

Hibernation is not working after upgrading frmo Jessie to Stretch.

2018-06-01 Thread Piotr
Dear all,

Recently I upgraded my Debian Jessie to Stretch and I noticed that hibernation 
does not work anymore.

When I try to hibernate to disk the process of saving the current memory state 
seems to be doing the job correctly. However, when I start the laptop I see 
that restoring the state begins, but in the middle laptop reboots and starts 
normal booting instead of restoring after hibernation.

Which logs should I submit in order to get some help?

Kind regards,
Piotr

Any hints where to start and what to look for?

I bought this mouse because it was really silent and cheap (APOINT M302) and it 
was working with Debian Jessie.

https://www.aliexpress.com/item/New-Bluetooth-Ultra-thin-Rechargeable-Wireless-Mouse-Silent-Button-2015-computer-mouse-for-laptop-gift-mice/32368987723.html?spm=a2g0s.9042311.0.0.27424c4dCuQb1a

Officially Linux support was not mentioned, so it might be difficult to find a 
drivers for it.
I wonder what was changed between Debian releases  that this mouse is no longer 
working correctly? For me looks like a regression which should be fixed. Should 
I reported this as a bug? If "yes" then which module/driver should I specify as 
a victim?

Yes, I was able to successfully connect some remote controller/gamepad which 
also has mouse option:

Maybe I should also try with another BT mouse to see if it has the same issue 
or not.
