Si quieres algo más automático y al instante, puedes configurarlos en modo
RAID1 mediante software mdadm, luego configuras LVM y por ultimo el formato
para la partición y puedes dejarlo como NTFS si deseas.

Y luego creas un script que te avise del estado del arreglo cada cierto
tiempo.

Para crearlo configuras un arreglo con uno de los discos sin tocar el que
esta online, luego copias todo de A hacia B en arreglo y agregas A como
miembro del RAID1.

Sin embargo lo más sencillo como lo tienes configurado si haces un cron cada
cierto tiempo con rsync --delete te va a funcionar sin problemas.

Otra alternativa sería configurarlo usando zfs que permite configuraciones
RAID1 desde el mismo sistema de archivos, algo que tambien puedes evaluar.


Gracias por la información. Voy a estudiar RAID1 de las maneras que comentas
para ver su me conviene sustituir o no a rsync.


Hola

Te sugiero inicies probando en maquinas virtuales y cuando lo domines le 
heches mano a lo que tienes.


Puedes crear tres discos, uno de 32 GB para el SO virtual y dos discos 
de 6G identicos que emulen los 6T, llenas uno de datos y el otro creas 
el raid, luego que tengas montado el RAID1 con solo un disco, pasas del 
disco fuera del RAID al disco miembro del RAID y luego agregas el disco 
faltante sería el proceso asi:


1) Discos A y B.

2) Crear B como disco RAID1

3) Crear LVM en partición del disco B y crear volumenes lógicos.

4) Darle formato al volumen logico del disco B.

5) Montar particion del disco B y copiar de A a B, puedes usar Rsync, 
como prueba puedes crear un archivo de texto y colocar un archivo de 
video o de musica para validar con md5sum la integridad de los datos.


6) Destruir particion de A y crear particion en RAID1 y sumarla a 
miembro de B.


7) por medio de "cat /proc/mdstat" monitorear el proceso y estado del 
arreglo.


Cuando tengas comprobado el proceso hazlo varias veces y cuando lo 
domines puedes hacerlo en caliente.


Todo disco en RAID recuerda que debes cargarlo con mdadm y revisa como 
iniciar un arreglo con mdadm ya existente, no es del otro mundo, solo 
teniendo en cuenta que algo mal realizado puedes perder los datos.


OJO: Siempre respalda aunque todo valla a marchar bien pero siempre ten 
otro respaldo fuera del que ya tienes. Es recomendable un tercer 
respaldo externo o la nube, puedes crear un cloud con mega u otra 
solución en la nube para tener lo mas importante en la nube.

No uso Zimbra y tampoco sé qué servidor pop3/imap incluye pero si tienes
acceso a los registros del servidor (Zimbra) y te dice que falla en la
autenticación del cliente, tanto en Outlook como en Thunderbird, quizá
se deba a algún problema de incompatibilidad con estos clientes.


Zimbra hace uso de postfix es un set completo que combina, 
mysql+postfix+amavisd+clamav+ldap+dkim+dnscache+proxy+nginx y todo el 
set es completo para administrar el servicio, lógico que no es solo de 
instalar y listo, aunque funciona pero requiere algunos detalles para 
asegurarlo y protegerlo.


Pues luego de pruebas he detectado que es problema de la versión y solo 
cuando se actualiza usando el thunderbird del repositorio de seguridad. 
La verdad es que no he probado usar el cliente thunderbird compilado 
desde la fuente del autor.


Solo comento lo que me ha pasado y si otro usuario ha pasado por lo 
mismo comparto y tambien sea útil y tener esta platica.


Outlook no sirve, tengo muchos clientes que llaman por el mismo problema 
de que les pide credenciales ya sea que el servidor sea Zimbra, esten en 
Godaddy/Office365 u otro proveedor, ya los clientes hasta ya saben como 
corregirlo por que cada cierto tiempo les presenta lo mismo, cierra el 
outlook vuelven a abrirlo y todo bien nuevamente y a veces, deben cerrar 
Outlook ir a configuracion de la cuenta volver a pegar la credencial 
cuando solo cerrar y abrir no funciona y nos hemos topado que la 
credencial guardad ha sido corrompida o cambiada de la nada.


Con thunderbird no se corrompe la credencial pero queda desconectado de 
la red, es decir, solo es el cliente de correo Thunderbird bajo esa 
versión de ese repositorio "security" de Debian, recuerden que no he 
probado instalar el del proveedor.




Yo probaría a descargar desde la web de Mozilla, la última versión de
Thunderbird y lo instalas/configuras (los programa de Mozilla no
requieren instalación, se ejecutan sin más) en un equipo donde no lo
tengas para no mezclar perfiles ni datos.


La verdad es que voy a probar, pero siempre me ha encantado confiar en 
los aplicativos de debian que vienen en sus repositorios, hasta ahora me 
he topado con algo como este evento y hasta el momento solo ha sido con 
thunderbird. Pero crearé otro perfil y otra maquina y probare con el 
thunderbird desde la pagina oficial.


El detalle es que no lo hice por que siempre he buscado usar los 
paquetes de debian y por el momento me ha funcionado el paquete del 
repositorio principal de debian, no he probado la versión proveida de 
"Sid" podría probar pero por ahora hare testing como mencionas y les 
comento.




Con una instalación limpia de Thunderbird, crea una cuenta para
conectarte a Zimbra y mira qué sucede. Las migraciones de los perfiles
y datos de las aplicaciones entre distintas versiones no siempre
funcionan bien.

Problema de Thunderbird debian 11 con Zimbra


Hola chicos.

Quería saber si alguien presenta el mismo problema.

Por accidente se me actualizó el thunderbird sin darme cuenta, y de 
pronto empezó a enviarme como si fuera Outlook la ventana de usuario y 
contraseña.


Al inicio supuse que era un problema de red, ya que otra pc con 
thunderbird y el mismo debian no mostraba el error.


Al inicio no molestaba mucho, pues solo cerraba el thunderbird y lo 
volvía a abrir, pues igual que el outlook aun cuando le colocabas la 
credencial arrojaba error de credenciales y en el servidor zimbra solo 
recibía una sola vez el error de autenticación pero luego no se recibían 
los reintentos, es decir que por mucho que colocara las credenciales no 
eran enviadas al servidor remoto, por lo tanto al cerrar el thunderbird 
y volverlo a abrir, solucionaba igual que el Outlook el problema, sin 
embargo empezó a quedarme la espina y hasta pensar que era problema del 
zimbra probablemente, sin embargo lo descarté por que observé que solo 
empezó a sucederme en mi ordenador.


Por mera curiosidad consulte las versiones de ambos clientes y vi que mi 
cliente de thunderbird tenía la version "102" proveída del repositorio 
de seguridad, y la otra aún tenía la versión "91" proveída del 
repositorio principal.


Por lo tanto respalde la carpeta, desinstalé el paquete e instalé 
manualmente la versión "91" desde el repositorio excluyendo para 
thunderbird los demás repositorios, por medio de de una maquina virtual 
instalé la ultima versión de thunderbird para lograr abrir el backup y

Para mi sorpresa con esta versión no me ha dado inconvenientes, he 
habilitado el debug en thunderbird y no he visto nada extraño en los 
logs más que errores de autenticación.


¿Alguien ha presentado ese problema?

Ojo, que en mi pc personal con correos gmail, yahoo, hotmail no he 
presentado problemas en la versión "102", pero esta si me da problemas 
con servidores zimbra. También agrego que la versión de zimbra es la 
última y solo se presenta con esa versión específica del lado del cliente.


Si consideran que la versión es importante me indican, pero como ya he 
explicado el problema es independiente si el debian esta actualizado o 
no, o si el zimbra es la versión anterior o la última, con la versión 
"91" funciona sin problemas, sin importar las versiones del OS o la del 
zimbra, pero con el paquete proveído del repositorio "security" solo ese 
me da problemas. Por lo tanto he logrado concluir que la versión de la 
rama security es la que da problema.

Re: Cómo elegir entre dos tarjetas gráficas

Mi duda es cómo saber cuál tarjeta está utilizando, según el comando anterior 
infiero que es la integrada.
Desde acá si es una notebook, lo que tienes es una computadora con una 
tarjeta de video principal Intel y una secundaria de refuerzo y auxiliar.

Mi otra duda es instalar los driver de nvidia:
$ nvidia-detect
Detected NVIDIA GPUs:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF119M [NVS 4200M] 
[10de:1056] (rev a1)

Checking card:  NVIDIA Corporation GF119M [NVS 4200M] (rev a1)
Your card is only supported up to the 390 legacy drivers series.
It is recommended to install the
 nvidia-legacy-390xx-driver
package.
Una vez ya instalada la recomendación, ejecuto el comando:
$ sudo lsmod | grep -i nvidia
nvidia_modeset   1060864  0
nvidia  15888384  1 nvidia_modeset
ipmi_msghandler   118784  2 ipmi_devintf,nvidia
aclaro que antes de instalar el driver no arrajaba ningún resultado, sin 
embargo sigo sin saber cómo hacer que utilice esta tarjeta, si es que no la 
está utilizando ya.


Necesitarás configurar Optimus para definirle que se use solo para los 
paquetes que necesites que la usen. Entendería que vas a desear solo 
usar la nvidia como principal pero este tipo de laptops no funcionan 
así, es decir no es como una pc de escritorio que le adicionas una 
tarjeta de video y perfectamente puedes descartar la interna para que no 
haga uso del CPU.


Estas laptops con doble tarjeta gráfica es engañar al usuario, es decir 
tienes una tarjeta gráfica intel y cuando levantes alguna aplicación que 
le demande mas memoria, si usas windows y su driver, este hará el switch 
de forma automática. Con Linux debes configurarlo, y el paquete que te 
va a ayudar se llama "Optimus".


Últimamente existe hardware que viene con tarjetas de video discretas o 
mixtas y eso es lo que tienes en tus manos.


Significa que la tarjeta debe de funcionar solo cuando exista una 
demanda alta de video, puede ser automático o de forma manual indicando 
que tarjeta debe usar para cada software. Así por ejemplo que use Intel 
para procesadores de texto y consolas, pero que use la GPU para cuando 
se cargue un juego o "The GIMP, VLC, etc" por ejemplo.


Dale una ojeada a este link

https://wiki.debian.org/NVIDIA%20Optimus

Por lo tanto debes dejar la tarjeta Intel por defecto y luego que hallas 
configurado el paquete Optimus, empieza a definir que use la tarjeta 
NVIDIA para aquellas aplicaciones que te van a demandar video y para las 
cuales la vas a necesitar, como por ejemplo "The Gimp"


Yo tuve una maquina así con doble tarjeta de video, las laptops que 
vienen así te dará problema si colocas la tarjeta NVIDIA como principal 
y no es recomendable ya que su utilidad es ser esclava y funcionar solo 
cuando lo requiera en este caso no están diseñadas para tomar toda la 
carga y solo procesar los hilos que les indiques, en este caso cuando 
levantes un software como "The Gimp" solo tendrá esa carga sin todo lo 
demás encima por lo tanto tiene como objetivo que te funcione de forma 
transparente para ti y tengas la sensación de que mientras proceses 
video, puedas seguir funcionando tu Sistema Operativo de forma fluida y 
nítida.




Muchas gracias y saludos!

Yo he usado f.lux y no es tan malo

Hay que tener presente que algunos programejos consumen más recursos que otros 
llegando el caso a consumir mucha CPU en PC algo viejas. Así que cuando 
instales alguno, controla el consumo de recursos y si ves que es mucho 
desinstala y prueba otro.

En cualquier caso, conviene tener sólo uno habilitado para que no

¿Podrías prestar atención acá primero? Dice que no puede iniciarlo y 
colocarlo al puerto 9050 por que ya hay algo que esta corriendo ahí, si 
sigues con el problema es que haz instalado y reinstalado y tienes otra 
instancia ejecutandose ahí.

Revisalo mediante el siguiente comando:

netstat -anop | grep 9050

Sugiero que hagas primero lo siguiente:

dpkg -l | grep -i tor

Y sugiero desinstales con la siguiente linea colocando cada paquete que 
encuentres relacionado a Tor

apt --purge remove [paqueteAremover]

Una vez limpiado, prueba reinstalarlo nuevamente, debería ya marcharte bien.

Puedes asegurarte que no exista ninguna instancia nuevamente revisando con

netstat -anop | grep 9050

Una vez que no aparezca ningun software que halla hecho "bind" a ese 
puerto, prueba iniciar tor

Es bien claro el error. Tienes otra instancia u otro programa usando ese

Si has instalado el paquete de Debian, ejecuta mejor
«torbrowser-launcher» para iniciarlo.

Le dará el mismo problema, ya que el problema que muestra es que el 
puerto ya esta siendo usado, si tiene otro tor ejecutandose que primero 
elimine como indiqué anteriormente y luego solo instale una sola 
instancia según la wiki.

No, he tenido experiencia con ese.


Sin embargo depende de lo que deseas realizar, si es realizar una

Incluso sincronizando entre equipos remotos no accesibles pero que 
tengan salida a internet, creando un vpn entre ambas y luego un rsync.


Otro metodo es usar mega, o alguna nube y mantienes sincronizado en 
ambos lugares.


Si ya tienes una nube rclone, lo que lei es para sincronizar algo a una 
o varias nubes. Esto sería útil si no quieres tener el cliente de cada 
nube instalado por ejemplo.


Por el momento yo he usando rsync para sincronizar entre dos objetos, ya

Vulnerable git in bullseye - what's the process?

2023-01-27 Thread Sijmen J. Mulder

Hi all,

I was surprised to find that the recent git vulnerability hasn't yet
been addressed in Bullseye:

https://security-tracker.debian.org/tracker/CVE-2022-41903

My question isn't about the situation of this package per se but about
the process. I found this diagram:

https://wiki.debian.org/DebianReleases#Workflow

It shows how packages go from unstable to testing, stable, etc. with
'security' having a direct route from the security team. 

Now what I wonder is, is that part of the process visible somewhere?
Can I see if there are yet patches submitted, if there are builds
failing, etc? Generally just interested in seeing what's going on
there. Perhaps contribute.

(Let me be clear - I am NOT demanding support from anyone or
complaining.)

Gene,

Er zjn een aantal dingen die je kunt doen:

 1. Als je eigenlijk helemaal niet zo'n behoefte hebt kun je
programma's configurareren om geen kleur te gebruiken. Dat doe ik
meestal. In het bijzonder heeft de standaard Debian ~/.bashrc een
hele sectie die kleur configureert. Ik heb dat er allemaal
uitgehaald. Je kunt ook NO_COLOR=1 in de omgeving definieren, een
aantal programma's respecteren dat.

 2. Veel programma's gebruiken het basispallet van 16 kleuren. Dit
pallet kun je aanpassen in de voorkeuren van de terminal, dan kun je
bijvoorbeeld een andere, leesbare, tint aangeven voor 'lichtblauw'.
(In MATE Terminal vond ik het standaardkleurenschema al aardig.)

 3. Andere programma's die 256 of 'ware kleuren' gebruiken moet je soms
handmatig configureren.

Hopelijk heb je hier wat aan.

What I'd really like to know is,  why is this happening now when it wasn't

Interesting!  I see a few of files named "web" in the process table,  probably 
a slight version difference there. I'll have to keep that in mind next time 
things reach that point.  Right now each one is using 2-3% of CPU and a 
nontrivial amount of space.

I have noticed similar behavior here,  and the culprit seems to be firefox.  If 
I ignore it things get sluggish, and then the machine starts to thrash,  until 
the only recourse is the power switch.  If I notice it in time,  close firefox 
and restart it,  the memory used after I do that is significantly less than it 
was before.

Somewhere in their help or documentation they even say that you shouldn't leave 
it running for extended periods of time.

I wish they'd fix it!

Re: Debian 11: Tuning kernel parameters swappiness and watermark_boost_factor to stop SWAP Storm

2022-01-29 Thread Steven J. West

Thanks, Nicholas :D  I mainly posted this problem with a solution here for
reference to other Debian users ;)

Yes, my processing memory requirements (typically ~30GB) are borderline to
my current physical memory limit (~32GB), and as my images sometimes are a
little bigger, this can push it into swapping, which indeed is not ideal..

I am modifying my code to batch this procedure to lower the gargantuan
memory requirements of my image registration task, but in the meantime, for
processes with large memory requirements that may occasionally need to
swap, I found this kernel tuning at least allows the process to complete.

Cheers!

Steve.

I'll second this.

I had a "refurbished" Thinkpad that I used rather extensively for _six years_ 
before something went wrong with it and gave me a "system board error".  No 
issues with running linux on it at all,  though I was running Slackware at the 
time.

Bullseye Installer Fails to find soundcard

2022-01-14 Thread David J. J. Ring, Jr.

I'm just a user.  I've been trying to install Bullseye since the Release 
Candidates, no luck.

The accessible text installer fails to find my sound card.  I think my sound 
card is the 
second one that Debian finds, so I select that.

I do get sound in console once installed, but a blind person would not be able 
to install
as there is no sound, unless they had a braille device.

I've contacted debian-accessibility and debian-boot, but I just don't know 
where the problem
is, Samual from debian-accessibility says it's alsa, but I'm not a programmer, 
or developer, I'm
just a user.

I've spent hundreds of hours trying to install Debian Bullseye.  The last 
release of Debian Buster
installs perfectly, it detects my sound card, I have sound during installation, 
and upon reboot.

But suddenly in Debian Bullseye, something has changed. No sound during 
accessible text installtion.

I don't know who to report this bug to.

Best wishes,

David

This is funny,  I remember when an 80MB drive was *huge*.   :-)

I'm aiming to clean things up a bit so that I don't end up downloading stuff I 
don't need,  and never use.  Save myself some time.

Yeah,  I could do that if I had those resources,  but I don't.  In the meantime 
I'm finding aptitude to be a useful tool for the job...

Apparently the info about what's in this directory is also stored in some 
database somewhere,  so just going in there and deleting a bunch of stuff will 
probably break something...

Somebody (maybe more than one somebody) suggested a "clean" option,  but 
apparently that will get rid of *ALL* of those files.  I'd kinda prefer to keep 
the most recent of any of them that are still being used.  In perusing the docs 
for aptitude,  I see that there's an option in there to "clean obsolete files", 
 which sounds like it'll do just that.  I don't see such an option in apt-get,  
or elsewhere (so far).

Yes,  it is nice having a choice about these things.

I think that the default for aptitude is to not do what I mention above,  but 
it also appears that it's possible to make it do that by default by fiddling 
with a config file.  This would appear to be detailed in the section of the 
docs entitled "Configuraton File Reference",  which talks about what files are 
used (and their locations),  and then lists all of the options that are or can 
be in those files.

Yeah.  But the detailed docs for aptitude are a whole lot more interesting and 
more detailed/explicit.

From what I understand I should be able to get the software to show me what 
it's planning on doing before it actually goes ahead and does it.   :-)

freeing up some space

So I'm poking around with mc,  and happened across /var/cache/apt/archives 
which has a LOT of *.deb files in it, and which seems to include many versions 
of the same package,  some of them many years old,  going all the way back to 
2013.  I guess I've been running debian a little longer than I'd thought...

Is it okay to just delete older versions of these files?  Or should I be doing 
something using one of the package management tools?  I've mostly used 
synaptic,  but am also aware of apt-get,  apt,  aptitude,  and am not real 
clear on their comparative capabilities.

I'm looking at over 7500 files amounting to over 9.5GB.

I also see /var/cache/dictionaries-common,  which appears to be tied to a 
spelling checker,  which I don't use here.  And /var/cache/samba,  which I also 
don't use -- there isn't a windoze machine around here at all.

What's the best way to get all of this excess stuff out of the system?

Right.  I don't see any mail that seems to be pointed at root,  though I do see 
a /var/mail/roy file,  I should probably see if there's some way that I can get 
kmail in the virtualbox to import this stuff.  Suggestions as to how to do that 
would be welcomed.

It doesn't seem terribly useful.  The latest ones in there are referring to 
/var/log/exim4/paniclog as having a non-zero length,  and quotes some lines 
from it.  Which refer to something that didn't go right in September of 2017!

What's puzzling to me is why it worked okay before my most recent upgrade,  and

How does that "on demand" thing work?

This was 8,  moved to 9,  and I will (eventually) progress all the way to 11.  
But not just yet.

I don't do anything much under debian that needs to have sound working,  so I 
hadn't noticed a problem until the virtualboxed Slackware didn't have sound any 
more,  and there are a few things I do in there where I *do* want sound 
working.  Firing up another instance of it at somebody's suggestion took care 
of that problem,  though I did have to reboot the virtualbox in order for it to 
see it.

According to /etc/debian_version 9.3...

I often log in as root.

The initial login screen is graphical,  from which I can select different 
desktop environments.  At the moment (and for quite a long time) I'm running 
Xfce.

I'm not sure I understand the question here.

> How does Pulse Audio get started (if you know)?  What do you see in "ps"?

Looking at it in System Monitor,  I see two instances of it.  One has the user 
name "Debian-gdm" and when I mouse over it shows "parent = systemd".  This is 
the one that the system starts up.  The other one is the one that I started 
from a command line,  which is otherwise the same.  Right-clicking on either of 
these and selecting "show detailed memory information" shows very different 
results for the two of them,  more memory being used for the second instance.

> What are the exact symptoms?

I'm not seeing any symptoms on the debian side of things,  but haven't tried to 
do much with sound there.  The sound _does_ work when,  ferinstance,  I view a 
video on youtube or similar.  When booting the virtualbox,  I'd get an error 
message from Slackware that it wasn't able to connect to the pulseaudio daemon 
and was going to use the "null" audio device instead,  meaning that sound 
didn't work in there at all.  After invoking pulseaudio in a terminal on the 
debian side of things and rebooting the virtual box sound in there works fine.

See the above paragraph about during the boot process of the virtualbox.

> What steps do you perform when you restart Pulse Audio?

I haven't tried restarting it,  just firing it up as someone suggested,  using 
pulseaudio --start in a terminal window.

> What does "ps" show after that?

Not using ps here,  for the most part.  I'm looking at stuff in System Monitor.

I'll get a handle on this sooner or later...

I don't see the need for this.  Deliver mail locally where?  And to who?

I've been surprised at that more than once already.  I suggest to synaptic that 
I might want to remove something,  and it comes back with a *huge* list of 
stuff that's going to be removed,  if I do.  I can't quite make sense out of 
that.

Still working on that...

Not necessarily wrong,  but definitely different.  I like the management of 
dependencies,  one of the reasons I chose it.  Some of the other stuff I'm not 
so sure about,  though.

Oh,  it's different all right.  Bothersome?  Sometimes.  I've been dealing with 
it for some years now,  and haven't given up on it yet.
