Re: annotations de PDF

  voir xournal

+ 1 pour Xournal.

 
 Quelqu'un aurait-il une expérience à partager sur xournal ?

Vi. Je l'utilise tous les jours, depuis ± 4-5 ans, sur Tablet PC en
déplacements, réunions et rendez-vous, et couplé à une tablette
graphique sur desktop, pour prendre des notes manuscrites, faire des
schémas, étudier et annoter des documents.

IMHO, en trois mots, c'est un killer du Micro$oft Journal fourni sous
XP TPCE.

À la base, Xournal est dédié à la prise de notes manuscrites sur
Tablet PC, sur papier vierge ou en annotation de fichiers PDF.

Il est assez simple d'utilisation, et bien que plutôt basique dans ses
fonctionnalités, l'absolument indispensable est là, et marche
extrêmement bien.

En annotation de PDFs, puisque c'est ce qui t'intéresse, il fonctionne
en créant un fichier Xournal associé au PDF (même nom que le PDF +
extension .xoj, mais c'est modifiable), qui contient la couche
d'annotations.

On peut à peu près tout faire, en termes d'annotations... Que cela
soit à la main ou au clavier, en passant par le surlignage au fluo
numérique et le tracé de figures à main levée, avec détection de
formes.

Il permet ensuite de réexporter un PDF tout à fait décent avec les
annotations ajoutées.

Personnellement, je suis enchanté de le voir s'acquitter à merveille
de toutes ces tâches, si l'on garde évidemment à l'esprit
l'utilisation avec une tablette.

IMHO, elle est indispensable pour en profiter complètement et surtout
naturellement, c.-à-d. en remplacement du papier et du stylo, pour de
l'écriture manuscrite (pratiquement impossible au mulot...).

Sans tablette, l'intérêt de l'application diminue à mon avis
fortement, même s'il ne devient pas nul pour autant. (Les annotations
en texte saisi au clavier restent possibles, en positionnant un champ
texte n'importe où dans le PDF à la souris. Même si c'est beaucoup
moins naturel que de pouvoir gribouiller comme sur un papier, pour
certains trucs il reste que ça dépanne.)


Quelques truc géniaux et rapides :

- le remplissage de formulaires à trous scannés : ça trace :-) On peut
  même faire bien propre en saisissant les infos au clavier quand
  c'est possible) ;

- la signature d'actes juridique scannés : économie de temps
  intéressante si toute la chaîne est numérique, par exemple. L'acte
  arrive par mail ; on fait un PDF, on le signe et date à la mano dans
  Xournal, et il repart, exporté en PDF ;

- l'annotation d'une capture d'écran (que Xournal permet directement)
  pour dépanner un pote dans l'ornière ;

- les schémas rapides et notes de réflexion, vautré dans le divan avec
  un Tablet PC :-) ;

- etc.


Voilà mes 0.02 € :-)

Tu devrais l'installer et voir par toi-même...

Mais toujours à disposition si tu as des questions précises.

d'attendre que le système soit complètement opérationnel avant de 
starter les base oracle. on peut bien sur rajouter une detection du 
point de mount NFS pour ne pas starter la base en absence de NFS, mais 
le but principal est qd meme d'avoir un serveur qui démarrer avec ses

[TOTAL HS] sfr gmail #~x@!

Salut liste  désolé pour le HS complet,

de vos connaissances ayant un adsl sfr et un compte gmail parce
que je viens de recevoir un email très zarb:
une demande de confirmation d'ajout d'adresse email (sfr) à mon
compte gmail.

Or c'est l'adresse de base automatiquement fournie par sfr lors
d'un abonnement, que je n'ai JAMAIS utilisée; pas plus que je
n'ai demandé un quelconque lien entre les 2.

Soit cela vient de gogol parce que le compte avait été créé avec
mes nom  prénom et qu'ils savent que sfr fourni par défaut une
adresse email au format nompre...@sfr.fr, mais je n'y crois pas
vraiment parce que ce compte est en fin de vie; 
soit ça vient de sfr qui aurait donc  vendu cette info à gogol,
ce qui ne m'étonnerait qu'à moitié vu qu'il-y-a 2-3 mois j'ai
reçu un appel (non-masqué, mais avec seulement 8 chiffres) sur ma
ligne internet (en LR!) de canalsat pour essayer de me fourguer
un abo - après avoir haussé le ton, j'ai fini par savoir que
c'était sfr qui leur avait directement refilé mon n°.

Étant donné que j'aime pas les cons et que ça fait 2 fois qu'ils
se la joue à l'Américaine, si certains d'entre-vous ou de vos
connaissances sont dans le même cas, ça m'intéresse, parce que
c'est quelque chose qui pourrait bien finir dans un tribunal en

 el problema esta en que luego de aparentemente instalar el software me
 lanza el siguiente error:
 
 Unable to build kernel module.
 see log file /tmp/vmware-root/setuo-6031.log for details.

Y por curiosidad ¿qué te dice ese archivo?

 al parecer existe un parche para corregir este error pero no tengo ni

Si es asi, parchea init_module, que se llama cuando haces insmod, y con

 Si es asi, parchea init_module, que se llama cuando haces insmod, y con
 printk escribe un mensaje a la consola que se mostrará cuando lo
 cargues, para tener la certeza de que tu código esta ahí.
 
 Mmmm, mm... sigo sin enterarme. ¿Algún guía-burros que pueda seguir 
 con instrucciones sencillitas de tipo primero haz esto, luego haz esto 
 otro, después ejecuta esto y por último edita esto otro?
 
 Si no es asi, lo siento, pero no he entendido lo que pretendes.
 
 No, no... es eso mismo.
 
 Saludos,
 

bueno, pues a ver, si cuando haces el patch no te da error, ni cuando
compilas el kernel tampoco, quiere decir que debe haberse parcheado y
compilado correctamente.

En todo caso, si el código de tu amigo declara alguna función o
variable, es posible que puedas cerciorarte con objdump,

objdump -t modulo.ko

debería listar la tabla de símbolos del objeto, si aparece la función
declarada en tu código, voila!

Por último, lo que te comentaba antes era que tu misma añadieses al
parche un printk, que es un como un printf de libc de toda la vida,

http://www.kernel-labs.org/?q=printk

en la función init_module(), que es la que se llama cuando cargas el módulo.

Un saludo.

liberar SWAP al apagar equipo

2012-04-05 Thread Ricardo Delgado

Buenas, hace unos dias cifre la particion (nuevamente) pero sin cifrar
SWAP, ahora bien, segun tengo entendido es importante cifrar SWAP pero
no lo hice, en su defecto mi idea es borrar el contenido de la
particion SWAP al cerrar sesion o apagar el equipo. de forma tal que
ante la perdida de mi portatil, no se pueda acceder a la info guardada
en la particion de intercambio.

eso es posible? alguien podria indicarme si lo hizo y como?

gracias

problema alsa debian squeeze

2012-04-05 Thread Alejandro García

Ante todo un cordial saludo.

 Me dirijo a la lista para realizar una pequeña pregunta, pero antes
explico mi problema.

 Tengo un Ordenador con tarjeta madre intel d101ggc con procesador Dual
Core 3.0ghz, 1.5gb ram, capturadora de tv encore, más impresora samsung
ml1740 y por ultimo una tarjeta de video nvidia geforce 8600gt 512mb Vram.
El cual con debian lenny 5 ¡todo! me corre perfecto.

 Pero decidí actualizarme a debian, o sea, formatear la particion donde
tengo intalado debian, ok... ningún problema en la intalación ni en los log
de arranque del sistema

 Cuando comienzo a escuchar musica el volumen no puedo modíficarlo,
allí me doy cuenta del problema..

 Ejecuto alsaconf y posteriormente al reiniciar alsamixer. Ah! el lspci
me muestra HDA intel ati higth audio.

 Y noto el problema que el MASTER de audio solo tiene la funcion de
mute y PCM si se puede subir y bajar su volumen pero hay aplicaciones que
pasan por encima del PCM y en kde me pasa que cuando inicio casi me quedo
sordo con el sonido de bienvenida. y eso no me pasaba en debian lenny
ya que practicamente todo tenia que pasar por PCM y luego MASTER.

 Ahora mi pregunta es ¿cómo puedo hacer que alsa me trabaje ya de
una vez solo que el MASTER y dejar el PCM de lado?. o sera que me toca irme
de nuevo a debian lenny??? y actualizar el navegador manualmente hasta que
cambie algun dia de pc o me descargue el primer cd de debian testing y
pruebe a ver si tengo suerte.

 Espero su ayuda ya he probado con info de varios foros incluso me
instale en squeeze los paquetes de alsa de debian lenny pero no resulto es
lo mismo.

mdadm: no devices listed in conf file were found

2012-04-05 Thread Antonio Sanjuanes

Saludos lista,

Llevo una semana con esto, he intentado de todo ...  y ya agote las
opciones.

Primero trataba de instalar /boot en un volumen LVM, pero quedaba pegado y
parpadeando el cursor.

Ahora de 4 discos de 18.2 GB, creo una particion de 200mb en cada disco,
para dejar una para /boot activa y las otras sin usar.

con esto me queda la particion boot fuera del lvm, y 4 discos de 18gb.

pero ahora otro problema, creo el raid5  con los 4 discos de 18GB
,configuro LVM y al finalizar la instalacion  y reiniciar me manda este
error.

mdadm: no devices listed in conf file were found

Agradeceria la ayuda ya que no quiero usar otra distribucion.

Só que esse pacote só tem no mirror não oficial do debian que é o

Gostaria de saber o que vcs fazem para lerem midias originais e quais

 That depends on how you want to use your NAS. (protocols? clients?
 backup?) Generally, an appliance-like OS such as freeNAS will be a lot
 easier to set up and get running, for 90% of use-cases, and very
 difficult to configure for the remaining 10%.
 

NFS/CIFS etc ... which should work with all the os boxes... Linux/windows/Mac

 With a more general OS (such as Debian) you will be able to tweak it to
 do whatever you want, but you will have to learn about the technologies
 you need one-by-one rather rather than setup-and-go.
 
Interesting. How can I then go for a debian based NAS box ?
It will be fine if I get a minimal system working as NAS but
better if any web gui available. It would be great if I can
run the base OS from any USB or flash card and use the entire
HDD for backup.

remote mysql is too slow

2012-04-05 Thread J. Bakshi

Hello,

I have been provided a muscular linux server to use as a Mysql server
in our organization. The server is located just beside the web server
and within the same network. This dedicated server has 8GB RAM, i5 processors
and running mysql as service. No apache, php . nothing. All resources are
dedicated to mysql only.

Mysql version - mysql  Ver 14.14 Distrib 5.1.49, for debian-linux-gnu (x86_64)

The BIG hitch is; when we connect with this box the web sites become too slow.
I have added the following at my.cnf under [mysqld] section

` ` ` ` `
skip_external_locking
skip_name_resolve
skip_host_cach

` ` ` ` ` `


The sql connection becomes little faster but still it is considerably
slow; specially with such a muscular dedicated linx box just for Mysql.
Is there anything else which I can add/configure to make the network latecy
small or any such mechanism to make the query fast ?

The server has very little load as observer from top and iostat
even during peak hours.

Thanks

Problem with gdm auth

Hi

i configured an ldap server on debian squeeze and a client ubuntu 10.04.

Trying to login from login screen of the client using ldap user

Trying from a shell with the command

it runs.

Checking in /var/log/auth.logi found these messages:

Re: Exim4 and SMTP relaying.

 Referring to my http://142.103.107.138/NetworkExtant.jpg diagram,
 mutt and exim4 running on Dalton can send a message, through port 465
 with TLS, to *.webwelcome.com and then to a destination.
 
 Next I want to have Cantor send a message through exim4 on Dalton.
 The connection from Cantor to Dalton should be plain old SMTP with no 
 authentication and no TLS.  Which configuration options will allow
 this? I've spent a few hours searching and reading in the manuals and
 not found anything helpful; or perhaps just missed relevant options.
 

OK, it's a few years now since my exim4 was at that stage, so I'm not
really sure what is necessary...

... but to start with, locate /etc/exim4/update-exim4.conf.conf and see
what's in it. There should be an entry which may be empty called:

dc_relay_nets

which should contain network specifications separated by colons and
enclosed in single quotes. My guess for a first try is:

dc_relay_nets='172.24.1.0/24'

on the basis you're using a /24 netmask there. I don't believe that
exim4 by default checks sending domain, From: or anything else in the
message. It is also possible to relay by sending domain specification,
using dc_relay_domains, but that's probably not what you want here.

After the change, run update-exim4.conf and restart exim4.

My 5 cents: :)

* Do you have anything in your mysql's slow query log?
entries look like (see below) and can point you in the right
direction. As maybe is a SQL bad programming problem, lock between
tables, etc
.
# Wed Apr 4 13:08:27 2012
# Query_time: 1.494178 Lock_time: 0.00 Rows_sent: 0 Rows_examined: 0
use elsotani_X;
SET timestamp=1333566507;
CREATE TABLE IF NOT EXISTS `wp_translate_langs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(25) NOT NULL,
`main` tinyint(1) NOT NULL default 0,
`order` tinyint(1) NOT NULL default 0,
`icon` varchar(20) NOT NULL default '',
PRIMARY KEY (`id`)
)

* Is your DNS server responding quickly? Just a quick check.
add the IPs server names to /etc/hosts in mysql server and clients
and see if performance is better. I have seen that you have
skip_name_resolve and skip_host_cache parameters set, but this
solves (workaround) only the servers' side not the clients

* Anything wrong in your apache's logs?

Keep us informed about your progresses.

I hope it helps :)

Best regards

Re: Make fully encrypted disk without LVM during install

 Ever tried to put a fully encrypted disk with LVM in another machine, without 
 booting from it?

Far worse: I have a 1TB external drive with a DOS partition table, one partition
formatted for LVM, with an LVM logical volume on top which is part of an md RAID
set, inside the RAID device is another LVM PV for a different volume group. Your
point is correct: it is far from user-friendly ☺

 However, for this sitation I need something a bit more userfriendly.
 Preferably a scenario where my customer only needs to enter his password when
 mounting. That's why I thought of leaving LVM out of the picture altogether.

What environment is available in the system that might need to interpret the
device? My GNOME desktop can mount LUKS/dm-crypt devices graphically, via
nautilus (I think using udisks[1] as the back-end but I can't see the package
dependency relationship)

[1] http://www.freedesktop.org/wiki/Software/udisks

 In this situation it has no purpose at all, so why use it then?

If you are using the entire disk and don't anticipate needing to shuffle things
then there's no point indeed.

Looking at the messages above, you have an ATI Radeon-based video card.
'lspci' should confirm that.

Try appending video=radeon:off to your kernel line to get VGA mode

 It's possible it can already be done (by someone knowledgeable), but I

 Perhaps just alias some logging to dpkg?

Why dpkg? Since all packages are installed through dpkg I think a

Do I need exclude video=LVDS-1:640x480 from GRUB_CMDLINE_LINUX for

And where I need place my record ipv6.disable=1 - in the string

 I agree, that would be a very useful ability. I've recently had to deal
 with a, um, differently designed network where the boxes mixed
 releases and had a lot of self-built packages. Such a capability would
 have saved us considerable time.
 It's possible it can already be done (by someone knowledgeable), but I
 don't see anything in dpkg status or logs that hold that info.

 Perhaps just alias some logging to dpkg?
 
 Why dpkg?

Because all packages are installed through dpkg :-D
ie. that would allow the log to show whether dpkg was called directly or
not.
At least that was my initial thought[*1]. But I suspect it'll only
work if using a package cacher or proxy logging (and it turns out to be
a waste of time then).


 Since all packages are installed through dpkg I think a 
 possible implementation would mean diff'ing the list of installed 
 packages with the list of packages installed via apt-get/aptitude. 

Sort of. My original idea was that if dpkg was called directly then a
repository was being used - turns out to be wrong[*1], but the following
scenario might work[*2].
I could query a list of installed packages against
apt-cacher/packages[*3], as those package managers always result in a
file being added to the package cache there.
apt-cacher/private might be used to tell me which repository they came
from.
apt-show-versions might then be used to show whether they're still
available.

 
 Kind regards,
 Andrei

[*1] I spent an entertaining hour this morning forcing an install of
xbmc debian packages onto Squeeze - to get around a broken system I was
forced to (pun there) use dpkg directly (even though they came from a
repository). So logging what called dpkg is unnecessary - the list of
installed packages minus the list of corresponding packages in
apt-cacher should show custom/non-repository packages. If those
(remaining) packages aren't beneath linux/debian/$release/packages then
I've stuffed up somewhere.

[*2] Provided my total lack of thought, planning, and research hasn't
overlooked an existing system that works better.
[*3] The office and client networks have software servers that include
an installation of apt-cacher, even when a local mirror is used.

RAID1 does not boot

Dear All,

i am a newbie, i tried RAID 1 installation on VM which was working
fine. now i tried to install the same scenario on physical machine. i
have two 300 GB Hard drives and i want to make a RAID1 every things
work perfectly. i created the RAID partition and then RAID device. i
created 3 partition on the RAID drive.

1./boot (1GB)
2.SWAP (not on RAID)
3./Root (300 GB)

now everything when fine to the end of the installation but the
problem is when i restart the machine after installation. it doest
boot however in VM machine it didn't happen.
but one thing i notice during installation it is giving me the message
the Kernel was unable to re-read the partition table on /dev/md0
(invalid argument) this means Linux won't know anything about the
modifications you made until you reboot you should reboot you computer
before doing anyting with /dev/md0.

 i tried Squeez 6.0.4 and
Lenny  several times and at the end  no-success.

kindly  Help!

Thanks,

MYK

Aaah, now I understand what you've describing (tiny screen, not tiny

If that't the case, then the BIOS setting and console-setup is the
solution, in which case ignore my previous suggestion.

 Hello,

 Is there anything else which I can add/configure to make the network latecy

Although you say all resources are dedicated to mysql only, I guess
they're not.

First step: run mysqltuner - this will give some rough recommendations
which will usually point people in the right direction.  Beware that
mysqltuner will always recommend setting innodb_buffer_pool_size big
enough to keep all InnoDB tables in memory - which is usually overkill.

if vmstat reports that CPU usage is low, and disk IO is low, this
points towards locking contention - which is entirely application
dependent. Hope you haven't used MyISAM tables when you intended to use
InnoDB tables :-)

if vmstat reports high cpu usage, and low disk IO, then the database
is probably in memory, and you need to look at one or more of:

  * queries scanning lots of rows (e.g. missing indexes)
  * for InnoDB tables: if innodb_buffer_pool is too small, but the
server has lots of memory, the linux kernel will cache disk
blocks rather than MySQL doing it. Which translates to high CPU
load and lots of cache hits. But in this case it is more
efficient to let MySQL do the caching rather than the kernel.

 
 The server has very little load as observer from top and iostat
 even during peak hours.
 
 Thanks

Depends. Java+GUI programs are usually designed to operate with a
graphical interface only. Being able to use them from the command line,
on OS startup for example, depends on how the program is written.

 
 I hope your help because I don't know if this is possible to do in

If it's possible  under Windows, it's probably possible under linux

your program.

 Bear in mind that, if you care about this, FreeNAS is BSD-based, just as

I have multiple feelings about this.

Firstly, I'd describe 'less mature' as an understatement ☺

If one wanted to use ZFS and Debian in production, they can use
Debian/KFreeBSD, possibly as a VM running on top of Debian GNU/Linux.

I'd certainly think it was worth seriously thinking whether ZFS was a
real hard requirement, though. Especially for home NAS purposes. In an
environment where ZFS fits naturally, such as FreeBSD, then it's a
no-brainer over e.g. UFS; but when you have to work to support it (e.g.
under Debian GNU/Linux) you should really ask whether it's worth the
effort and risk.

Yes, this is possible. Just to clarify, I'm assuming you want the
following to happen:
 * User powers on computer
 * Computer boots with no interaction needed, providing little to no
   feedback.
 * Once booted, the Java application is started, being the only
   application available to the user.

This is often termed Kiosk mode and that should help you find more
information. But basically, you will want to consider the following:

 * Set your bootloader (probably grub) to boot a default entry after a
   short delay (1 second should be enough).
 * Either boot with the kernel parameter quiet or, better, install a
   boot splash program such as plymouth. This allows you to hide the
   boot messages behind a graphical screen. That could, for example, be
   your own logo. You may or may not want a progress bar there.
 * At the end of boot, use a minimal display manager (nodm, perhaps) to
   start the graphics system (X). You would then configure the session
   started to use a minimal window manager (icewm, ratpoison etc) to
   automatically start your java application. You might consider running
   the java application as the only X client, but you may need to tell
   it the geometry of your screen so that it uses the full screen; a
   window manager would make that easier.

I'll leave it as an exercise to you what happens at shut down :)

There is more than one way to do it :)

Basically there are three things you need to accomplish:

A. automatic login for a specific user[1]
B. automatic start of X
C. start of the application you want (and nothing else)

A. and B. are easily solved with nodm.

For C. the typical advice is to use ~/.xinitrc, but I prefer to add the 
program as the default alternative to x-session-manager (see the manpage 
for update-alternatives).

[1] as far as I can tell, that user should be locked down. At a minimum 
create a new user and add to other groups (like audio) only if really 
needed.

Hope this helps,
Andrei

Re: Make fully encrypted disk without LVM during install

2012-04-05 Thread J.A. de Vries

Hi Jon,

 Far worse: I have a 1TB external drive with a DOS partition table, one
 partition formatted for LVM, with an LVM logical volume on top which is
 part of an md RAID set, inside the RAID device is another LVM PV for a
 different volume group. Your point is correct: it is far from
 user-friendly ☺

Ah, another fellow sufferer!

To us it is a problem we can overcome, but I'd like to present my customer 
something that'll be easier to do.
 
 What environment is available in the system that might need to interpret
 the device? My GNOME desktop can mount LUKS/dm-crypt devices graphically,
 via nautilus (I think using udisks[1] as the back-end but I can't see the
 package dependency relationship)
 
 [1] http://www.freedesktop.org/wiki/Software/udisks

Thanks. I hand't seen this, yet. 

The DE where the disk will be mounted is pure KDE. At the moment version 
4.6.3, but they expect to migrite to 4.8 in a couple of weeks.

 If you are using the entire disk and don't anticipate needing to shuffle
 things then there's no point indeed.

That's the case.

Thanks for helping!

 The BIG hitch is; when we connect with this box the web sites become

Is this in direct comparison to some other database or server, or is it

If it's slower than some other database system you're going to need to
look at your network topology and system configuration and compare like
for like as best you can.

If it's a simple statement of fact you probably need to look at
your application architecture. Are you - and should you be - using
memcached? Have you got indexes on the right table columns? Are you
using ISAM when you should be using InnoDB (or v.v.)?

  I might try whether KMail handles ignoring this thread. It sometimes
  seems to work at other times mails in the thread are still marked as

 This thread was (properly) tagged as OT and thus can be easily
 ignored/ filtered/avoided by anyone. Move on.

And I may perfectly express my astonishment about the size and the amount 
of off topic content in that thread.

I think it is important to have a balance.

I did not force you in any way to stop it, I just wanted to raise 
awareness on what you are doing here.

And everyone still gets each mail.

I also replied to the thread OTOH. But I think its good to settle it now /

 Hi everybody,

Hola Antonio :-)

(please, no html messages... thanks)

 I would like to get that a graphical application developed in Java runs
 on startup of a Debian machine, if is possible without menu, without
 login panel and without system messages. Obviously without update
 messages.

There are java applications that requie having an X server or need 
additional packages to be installed... what are the requierements for 
yours? Is it a standalone .jar file or daemonized service? And where is 
going to be run? I mean, what kind of installation, what do you have 
installed in your system (X server, window manager...)?
 
 I would to get a machine that works with this app on startup like as a
 information point center. Do you understand me?

Yes, you mean something like a kiosk mode, right?
 
 I hope your help because I don't know if this is possible to do in Linux
 Debian. I know that in Windows is possible but is more expensive than to
 do it in Linux (Licenses).

That will depend on the application requirements but basically you'll 
need to just call the java app on system start in the same you you'd do 
for another script/program.

 Looking at the messages above, you have an ATI Radeon-based video card.
 'lspci' should confirm that.

Re: RAID1 does not boot

Thanks, i found out the problem but still i am confused actually
i have disk 1 and disk 2 with same specs like they both are 320 GB
and same made. here is my partition flow
(because i had tried installation so many times so i change the
partition structure)

1. /Boot 1GB (Boot on and on RAID /dev/md0)
2. SWAP 4 GB (RAID /dev/md1)
3, / (remaining space) (RAID /dev/md2)

now at the end after installation when system rebooted for the first
time i receive error loading operating system actually in BIOS boot
option i mistakenly selected SATA2 as boot instead of SATA 1. when i
shift things back i manage to reach grub menu.

now the part where i am confuse is that i believed that the computer
should have booted from SATA2 as well because boot partition is also
installed over it too. as i have created /boot partiton on RAID which
was md0. now for instance if my SATA 1 goes down then i would be
handicap as it will not going to boot from SATA2.
please suggest me what should i do in this regard. because what i
want that, if some thing happen to any of the drive i just have to
unplug the bad one and replace it with the new one ofcourse i know i
have to make same RAID partition and stuff but what i want is if SATA1
Fails i want SATA 2 to boot with out any complex efforts.

Thanks

now everything when fine to the end of the installation but the problem
is when i restart the machine after installation. it doest boot however
in VM machine it didn't happen.

A virtual machine does not always helps to diagnose hardware related
issues and the VM can be using a different set of kernel modules for the
disks.

Anyway, what error are you getting when booting? Can you reach the GRUB's
menu?

but one thing i notice during
installation it is giving me the message the Kernel was unable to
re-read the partition table on /dev/md0 (invalid argument) this means
Linux won't know anything about the modifications you made until you
reboot you should reboot you computer before doing anyting with
/dev/md0.

i tried Squeez 6.0.4 and
Lenny several times and at the end no-success.

There are similar installation errors reported here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507653

But that shouldn't have additional drawbacks other than the warning.

My guess is that the problem here is booting from the raid volume.

RE: grub2 screen resolution

2012-04-05 Thread Bonno Bloksma

Hi,

 I do not understand the defaults build into Grub2. For instance the 
 default resolution, it is at 640x480. Which machine running Linux 
 cannot at least use 800x600? Or is Grub2 made with hendhelds as a 
 target environment as well?

 Yes - especially those squint-o-vision widescreen ratio netbooks.

Ok.

 Right now I have to add a line GRUB_GFXMODE=800x600 to the 
 /etc/default/grub file each time.

 Modify it then:-
 #update-grub

I know about update-grub, did not think I needed to mention that as it is 
needed for all changes to the grub settings.

 You might want to read /etc/default/grub first... (first line)
Like I wrote, I knew that. ;-)

RE: grub2 screen resolution

2012-04-05 Thread Bonno Bloksma

Hi Dom,

 Right now I have to add a line GRUB_GFXMODE=800x600 to the /etc/default/grub 
 file each time. That part I kan still understand, eventhough I think that 
 should be the default resolution.
 But I also have to change the /etc/grub.d/00_header script each time by 
 adding the line set gfxpayload=keep at the proper place.

 You should not need to change the 00_header script.

 Adding a line into /etc/default/grub, after the GRUB_GFXMODE entry with

 GRUB_GFXPAYLOAD_LINUX=keep
 
 should make grub keep the screen resolution.

AHA, an undocumented feature. At least, it is not documented in the 
/etc/default/grub file itself.

 You will need to run update-grub to regenerate and install the change 
 configuration of course.

I know abou that. ;-)

Re: Graphical app on startup

  I would like to get that a graphical application developed in Java
  runs on startup of a Debian machine, if is possible without menu,
  without login panel and without system messages. Obviously without
  update messages. 
 
  
 
 Depends. Java+GUI programs are usually designed to operate with a
 graphical interface only. Being able to use them from the command line,
 on OS startup for example, depends on how the program is written.
 
  
 
  I hope your help because I don't know if this is possible to do in
  Linux Debian. I know that in Windows is possible but is more expensive
  than to do it in Linux (Licenses).
 
 If it's possible  under Windows, it's probably possible under linux
 (debian or not debian). You need to check the command line options of
 your program.

I think they call it Android :-)

Re: Live Squeeze system: ConsoleKit does not see serial console as active, cannot mount with udisk

On Wed, Apr 4, 2012 at 9:30 PM, Jason Heeris jason.hee...@gmail.com wrote:


 I'm building a Debian Squeeze system with live-builder 3.0~a45 (from
 Ubuntu 11.10). I'm running into a problem where I can't use udisk to
 mount devices using a serial console on the live system (perhaps due
 to problems with consolekit or policykit).

 I configure a serial console using the boot line and some boot-time
 sedding to produce this line in /etc/inittab:

  T0:23:respawn:/bin/login -f user /dev/ttyS0 /dev/ttyS0 21

 My problem is this: when I try to use udisk to mount an image via a
 serial console, I get:

 
 user@my-live-usb:~$ udisks --mount /dev/disk/by-label/image-data
 --mount-options ro
 Mount failed: Not Authorized
 

 I read through a heap of forum postings and bug reports, and
 eventually figured to try:

 
 user@my-live-usb:~$ pkexec true
 Error executing command as another user: Not authorized

 This incident has been reported.
 

 Then I ran ck-list-sessions and saw that only Session 5, on
 /dev/tty1, has active = TRUE - the console I'm actually using
 (Session 1 on /dev/ttyS0) has active = FALSE.

 Am I right in thinking that this is why udisk is failing to mount the
 device when run on a serial console? I checked that my udisks command
 worked with a video console, and it does. But unfortunately, this is
 not practical - I need to be able to run the command at a serial
 console OR a video console.

 It's worth pointing out that under this live system, the default user
 (user) is automatically logged in on every video console and the
 serial console.

 If I look in /usr/share/polkit-1/actions/org.freedesktop.udisks.policy,
 there's a group of keys under action
 id=org.freedesktop.udisks.filesystem-mount:

  allow_anyno/allow_any
  allow_inactiveno/allow_inactive
  allow_activeyes/allow_active

 Changing the allow_inactive and allow_any keys to yes makes no
 difference. I figure that I somehow need to tell consolekit that the
 serial port is an active console. But how?

I haven't used polkit since Fedora 12 was released with weird package
installation defaults and I don't have access to the notes that I made
at the time so what follows is just from looking at a Sid VM that I
have running.

Re pkexec true: Is your user a member of the sudo group? sudo group
members can use pkexec via
/etc/polkit-1/localauthority.conf.d/51-debian-sudo.conf. If you
don't want that user in the sudo group, you can create a conf file in
/etc/polkit-1/localauthority.conf.d to allow it to use pkexec.

Re /usr/share/polkit-1/actions/org.freedesktop.udisks.policy: (It's
better to create a pkla file in
/etc/polkit-1/localauthority/50-local.d than edit a
/usr/share/polkit-1/ file) Does pkaction display the changed values
for org.freedesktop.udisks.filesystem-mount?

No idea what to say or do about your ck-list-sessions output, sorry.

After installing the kernel linux-image-3.2.0-0.bpo.2-amd64 I have
problems with fonts/video again: when loading new kernel I have a small
screen size so as in console as in X11.
I exclude video = LVDS-1:640 x 480 from grub configuration. After that
the new kernel load fine, but I have very small fonts in my console so
as last summer after upgrading from lenny to squeeze.
Have any ideas?

I'm not sure I understand what you're saying above

Try the following in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash nomodeset
video=uvesafb:mode_option=$finalresolutionanddepth,mtrr=3,scroll=ywrap

Then run:-
# update-grub

Where $finalresolutionanddepth is something like 1024x768-32 (eg.
800x600-24) depending on what you use on the desktop.

NOTE: this is not the same as as the xrandr instruction you are/were using.

Now I have the next configuratuon of /etc/default/grub:
GRUB_DEFAULT=2
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2 /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=
GRUB_CMDLINE_LINUX=video=LVDS-1:640x480 ipv6.disable=1
(which works well with the kernel from official distro but not with the
kernel from bpo).
Do I need exclude video=LVDS-1:640x480 from GRUB_CMDLINE_LINUX for
using your config?
And where I need place my record ipv6.disable=1 - in the string
GRUB_CMDLINE_LINUX_DEFAULT of leave it in GRUB_CMDLINE_LINUX?

Don't you have any values for GRUB_GFXMODE or
GRUB_GFXPAYLOAD_LINUX set in /etc/default/grub? You have to set
them to the resolution that you want to use.

GRUB_CMDLINE_LINUX_DEFAULT sets the command line for the regular
menu entry and GRUB_CMDLINE_LINUX sets the command line for both the
regular and the recovery menu entries.

A similar situation is described here:

FC11 GDM can't authenticate users from LDAP
https://bugzilla.redhat.com/show_bug.cgi?id=505319

That's for Redhat but you can read the comments to get an idea on what can 
be going on at your Debian box.

No problem.

  I read the manual and found out how to drop into the initramfs debug

  could be a faulty driver that I need to disable, but I know of no
  (efficient) way to find out which one. Ideally, I would load one
  driver at a time, and see when the problem occurs.
  
  Can anyone help? Or am I completely off track with this problem?
 
 Can you take a snapshot of the screen and upload somewhere? Maybe there
 is additional info alongside the Waiting for /dev to be fully
 populated message that can provide any insightful information about
 the source of the problem.
 
 I realize this complicates matters a lot, but the exact crash points are
 different each time. So I need to somehow get the log information out in
 text format and put it somewhere. I had the idea of getting udev to spit
 out copious amounts of debug information. The interesting thing is when
 I do this, 3.1.x seems to get stuck for a while waiting for timeouts. It
 does, however, still boot - unlike 3.2.x.
 
 Any ideas as to how I can get the information out without resorting to
 screendumps?

You can send the output to another machine using a serial cable and 
instructing the kernel to dump the message there. I had to do this years 
ago to debug a kernel crash from a VM but to be sincere, I doubt I can 
nowadays repeat that milestone, I don't remember the steps :-)

Look, Ubuntu has some good doc about this:

Kernel Debugging Tricks
https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks

The easiest way (which will allow you to read the screen) would be  
slowing the kernel output messages, I would start from there.

  I am running the latest packages in both kernel series, and the 3.1
  series does not have the problem.
 
 Are you using any special kernel module that may require to be re-
 compiled (as for example, the VGA driver) or any special module for the
 hard disk controller?
 
 My list of loaded modules follows (taken from 3.1.x). I have had some
 complaints about missing wifi firmware for a while (this is a desktop
 box, so I don't care about it) even though I have both
 linux-firmware-(non)free packages installed.

A message warning for a missing firmware could render that device 
inoperable but nothing more.

 Your help is very much appreciated.

(...)

Thanks for the module listing :-)

It seems that you're using a usual SATA configuration at the BIOS (ahci), 
I mean, nothing fancy that may require for specific hard disk 
controller module to be present and thus preventing the system from 
booting normally. 

Anyway, you can check if by appending rootdelay=9 to the kernel line at 
GRUB's boot menu you can get rid of the waiting... to be fully 
populated message.

 My guess is that the problem here is booting from the raid volume.

 Thanks, i found out the problem but still i am confused actually i have
 disk 1 and disk 2  with same specs like they both are 320 GB and same
 made. here is my partition flow (because i had tried installation so
 many times so i change the partition structure)

 1. /Boot 1GB (Boot on and on RAID /dev/md0)
 2. SWAP 4 GB (RAID /dev/md1)
 3, / (remaining space) (RAID /dev/md2)

 So basically you have now included /boot and /swap into the RAID, right?
YES both are raid volumes

 now at the end after installation when system rebooted for the first
 time i receive error loading operating system actually in BIOS boot
 option i mistakenly selected SATA2 as boot instead of SATA 1. when i
 shift things back i manage to reach grub menu.

 Okay, so now you get to GRUB's menu and then, what happens? Can you
 finally boot your installed system?


Yes. i can work normally as i boot from the grub menu.  there is no
problem at all. every thing is quite normal even here is the result of
cat /proc/mdadm

Personalities : [raid1]
md2 : active raid1 sda3[0] sdb3[1]
  307588416 blocks [2/2] [UU]

md1 : active (auto-read-only) raid1 sda2[0] sdb2[1]
  3903680 blocks [2/2] [UU]

md0 : active raid1 sda1[0] sdb1[1]
  1076224 blocks [2/2] [UU]


 now the part where i am confuse is that i believed that the computer
 should have booted from SATA2 as well  because boot partition is also
 installed over it too.

 (...)

 Mmm, IIRC software RAID (mdadm) needs from user intervention (manual
 tweaking) when one of the disks goes offline (or you alter the disk order
 at the BIOS ;-) ), at least for booting. I mean, you had to install GRUB
 in both disks or something like that, I dont't remember the exact steps
 but they should be documented...

Re: RAID1 does not boot

sorry to bother you again. can you please give or guide me from where
i can find instruction for installation grub on both drives.

Thank you?
