debian reinicio constante

[franiortiz hotmail]

Hola a todos pues algo muy raro, sintoma : cuando arranco mi particion 
debian de 3 años de uso en lenovo m55, se apaga-reinicia constantemente.
causa: en este orden cambios hechos :
1- instalar psensor
2- redimensionar y mover particion / (un disco, 2 particiones:xp+linux/)
3- actualizar
Al ppio pense que seria por temperatura, asi que limpie bien el pc, 
apenas sucio.
luego pense por discos o ram, asi que pase memtest, satisfactoriamente, 
los discos los miro con crystaldiskinfo y estan perfectos, por cierto el 
viejo xp y los livecd van perfecto, asi que descarto hardware.
4- supuse que al mover la particion (/) algo salio mal, algo que ni fsck 
encontro, que tambien probe. asi que reinstale 
debian-live-8.7.1-i386-standard-non-free.iso con lxde-core, lightdm y 
nada mas, todo actualizado y sorpresa la mia se vuelve a reiniciar solo 
con apenas paquetes en version stable.
5- empiezo a pensar que el fallo fue actualizar, voy a probar con la 
version 
https://cdimage.debian.org/cdimage/archive/8.6.0-live/i386/iso-hybrid/debian-live-8.6.0-i386-standard.iso
 
, a ver si consigo instalarla sin actualizar y que no se reinicie, pero 
si es asi, me las veo mal sin poder actualizar.
6- Esto es un bug?
Alguna idea? necesito volver a tener mi debian en este pc, que me estoy 
viendo obligado a usar mocosoft
Gracias, un saludo

Odd. If you do a web search with that number, you'll find a lot of posts 
mentioning this issue and all of them point to the same fix: get 
google's new key (file).



Possibly stupid question -- this is Jessie, does this mechanism of
dropping the files in trusted.gpg.d work properly in Jessie or is it
new?


Good question. Sven said it worked. I can't confirm that. It may be 
worth to try to import that key directly from a keyserver, like I 
suggested in my first reply:


sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 1397BC53640DB551

Saludos a todos,

Estoy retomando un tema que tengo pendiente desde hace algún tiempo
porque aun no lo he logrado poner en marcha. Me refiero a la
implementación de un AP wifi en una laptop DELL a la cual le he
instalado dos mini tarjetas wifi, wlan0 y wlan2.

Hasta donde he llegado he logrado que el AP montado sobre wlan0 conecte
a otros dispositivos móviles y también que la laptop se conecte a la
red(un móvil con zona wifi y datos móviles activados) mediante wlan2,
pero parece que tengo problemas con el enrutamiento ip desde wlan0 y
wlan2 en la propia laptop pues los móviles que se conectan al AP de la
laptop no logran navegar. Desde la laptop si puedo navegar, pero desde
los móviles conectados al AP de la laptop no logro navegar.

La ip del móvil con zona wifi y datos móviles activados es 192.168.43.1,
y la laptop toma la 192.168.43.156. Luego, el AP de la laptop tiene la
ip fija 192.168.42.1 y asigna bien ips al resto de móviles que se  
conectan.


Repito. Desde la laptop puedo navegar correctamente pero desde los
móviles conectados a ella no logro navegar.

Yes, one might expect items like this in a file maintained by apt!
You can also see from the head of the file that the most of the
"versions" are not the versions of the packages but are actually
constraints, ie dependencies/replacements/breakages etc. all just
jumbled up.

Within this jumble, I think it would be difficult to unambiguously
locate information that was specific to apt-cdrom or synaptic, were
either of these to add information not covered by your reference.

$ ls -l /var/cache/apt/srcpkgcache.bin 
... 22531192 Mar 27 21:00 /var/cache/apt/srcpkgcache.bin
$ strings /var/cache/apt/srcpkgcache.bin | wc -c
3655511
$ 
so the output of strings amounts to about 16% which means that
84% could be "hiding" other information from our eyes.

I've never looked at (let alone examined) these files after scanning
CDs with synaptic (assuming these same filenames are used), so I have
no idea whether they contain the same information as apt-get update
writes, or more. And as for what   man apt-cdrom   means by
"correcting for several possible mis-burns", I have no idea.

I am interested, but my free time is limited and I'm not sure where my position 
would be
on the learning curve. If you would be willing to give me an example of what is 
involved,
I might play with it a little to see if I think it is something I could learn 
how to use
without too many sleepless nights. :)

If you don't want to take the time, though, that's fine too as this is not of 
high
importance.

Thanks for the suggestion; it sounds like something that would work. 
Unfortunately, I
must work with something that already exists on my target systems (zenity does 
but not
yad) as it is not an option to add programs on some of these systems. Of 
course, you
could not know that as I had not stated it in my original post.

Thanks for your reply!

I have several different applications in mind, one of them is an automated 
backup of a
user's files using rsync in a shell script. The user triggers the script 
(possibly
using a desktop icon; no terminal or CLI involved) and is given the option to 
select which
external drive to use as the backup destination, and then rsync runs and dumps 
its output
into the zenity dialog, giving the user feedback of which files are being 
copied.

This is not a high priority problem, I just thought it would be nice to always 
have the
last lines visible instead of needing to manually scroll to the bottom.

Thanks for your reply.

Umm, openjpeg has also been removed from Stretch/Testing and Unstable

It has been replaced by openjpeg2:

Okay, now I see it.  Why is the package named "openjp2-7" instead of 
"openjpeg2-7"?  It seems to me that the latter would be easier to find.


Why is/was there a "libopenjpeg5" package?

Type the following:

$ mkdir /tmp/foo
$ cd /tmp/foo
$ zcat /initrd.img | cpio --extract --no-absolute-filenames
$ ls -i bin sbin | sort -nr | more

and you will see that the overwhelming majority of commands, over
180 of them, are all in the one busybox binary of a little over ½MB.
Were you to run a shell in the debian-installer (Alt-F2), you'd see
that all those commands are much less well-endowed than the versions
you know and love.

Cheers,
David.

I think that has less to do with conservatism and more to do with busy, 
unpaid maintainers doing what they can when they can, and probably 
getting narked off with it after a while especially if there is no 
evidence of appreciation from the community.

(I don't know any specifics of the busybox package, but what I describe 
wouldn't be atypical)

Right. So far it hasn't but I get what you are saying. I don't believe, 
however, that I ran for weeks getting redirected to the same mirror and 
getting the same error and then at the moment I switched my settings the 
mirror changed and solved the problem by coincidence. Clearly the change 
had an impact. So that's good.

Right, for the key issue, that has taken me right back to where I started:

W: There is no public key available for the following key IDs:
1397BC53640DB551

Now that is the only complaint, which is a significant improvement on 
where I started thanks to the fixed mirror, but the key ID issue isn't 
solved.

I tried naming the file linux_signing_key.pub.asc and 
linux_signing_key.pub.gpg.asc .

Neither worked (in the sense that the warning above appeared). Since 
this is the warning I was getting to start with, it almost feels like 
this file is either not being read (although naming it ending .gpg 
causes mayhem so I guess it is) or it doesn't contain what I need. I 
downloaded it using the wget command above except without the -qO- 
because I wanted to see what wget was doing and I didn't want the 
downloaded result going to standard output.

Possibly stupid question -- this is Jessie, does this mechanism of 
dropping the files in trusted.gpg.d work properly in Jessie or is it 
new?

busybox is a suite of tiny cut-down programs packed into a single

I have an example where this might be useful or then I am not
understanding the difference.

Let's say you have an executable package in the system and let's call it
pkgX
If you type pkgX in any prompt then /usr/bin/pkgX will be executed
But let's say you want to download and run a variation of this package,
edit its source and modify it, or just want to run separately a
standalone package in /xyz/packageX/pkgX
If you $cd /xyz/packageX and then $ ./pkgX the standalone would run,
right?  While pkgX will run the /usr/bin/pkgX
Alternatively in creating a local web-page set the ./index.html as the
site's root directory can easily be implemented in domain.net/index.html
and all links ./.html will work on the remote site.

PS  off-topic rant
I just updated and a package named busybox came up.  Since I didn't know
what it was I went into the page and its most recent revision of 1/2017
seemed to be 3 years ahead of the testing/unstable version that we just
updated now!  And this is very basic common stuff like cp and fdisk
..  How conservative is our system?  Wowww!

I believe that it is probably a good idea to dist-upgrade Jessie into an
up-to-date state before starting the upgrade to Stretch, but it is
certainly a good idea to do the intermediate steps of upgrading Squeeze
to Wheezy first and then to Jessie before starting the upgrade to Stretch;
with a direct upgrade Squeeze -> Stretch it is very likely (if not
dead-sure) that you won't get far.

My experience has only been with various stages of Jessie into Stretch

Como eu te falei, se o traceroute para no servidor, o próximo salto já 
seria o micro destino que está na rede VPN.
Parece que o servidor encaminha o pacote a ele mas não tem retorno, e 
por isso não aparece no traceroute.

But why on the first hand does debian-cd instruct xorriso to create APM ?
(By option -isohybrid-apm-hfsplus)

I understand from Matthew Garrett's blog and from discussions with
GRUB developer Vladimir Serbinenko that Macs which expect APM also
expect HFS+ with "blessed" files and not FAT with EFI files.

The Fedora ISOs have HFS+ images. grub-mkrescue ISOs can have HFS+.
But Debian and Ubuntu ISOs only have the EFI FAT filessystem image
in their APM. Is there any Mac known which boots only by this APM ?


Have a nice day :)

This looks bizarre. I think I must leave that to the DE gurus. I guess
it has to do with udisks (I think in its current incarnation it's
called "udisks2"), but it's beyond my depth.

As I say, it shouldn't. Lithium chargers don't provide a continuous
trickle charge. Various sources on the Net claim that life will be
longer if you never fully-charge the battery, but with a laptop, you're
always going to be looking for maximum running time. Supposedly it's
best to store the battery for long periods half-charged, but then
whenever you need to use the laptop, you have about an hour to wait for
full charge. You can't win.

Pretty much. The discharge protection should come in about 3V, but
might allow discharge a bit further. There is little energy left in the
cell at 3V. Here's a set of discharge curves at various currents:

Yes, certainly. That's why I said it's difficult to know what's going
on without either a known good battery or a known good charger. You'd
better hope it's the battery, as that is easy to fix...

The external power for the laptop is separate from the charger
electronics. The charger must supply a defined current, and if some of
this were diverted to run the laptop, it would be difficult for the
charger to monitor the state of the battery. So the external power is
supplied to two paths, to the laptop electronics and to the charger,
with laptop power being taken from the battery when the external power
is not present.

Right.
For whatever reason, libarted-based tools choose to consider that bogus 
Apple partition table. Unlike fdisk, you cannot force it to use another 
format.


Bottom line : libparted-based tools do not handle ISO-hybrid images 
correctly. Do not use them with such images.

I'd read the "Upgrades from Debian 8 (Jessie)" section in the Stretch

and doing a dist-upgrade.

I chose /etc/nsswitch because it is a *small* ASCII text file and any

Try the cupsfilter commands with /etc/services or any other text file.

As I understand it, writes smaller than a flash page size cause the 
flash drive firmware to fetch or erase an available page of flash, 
combine the unmodified bytes from the existing page with the new bytes, 
and then burn the page (and internal meta-data).  So, if flash pages are 
8K, burning in 512 blocks could cause 16 such operations, taking longer 
and eating up the life of your flash cells.  That said, RAM buffering by 
the operating system, RAM buffering by the USB flash drive, and firmware 
that anticipates serial writes should mitigate these effects.

Bueno, al final... conectaré mi AP a un portal cautivo -que es donde

hacerle ajustes pero ahora estoy trabajando en mi casa y para emular el
entorno y poner a punto el sistema tengo:

- Un móvil con zona wifi y conexión por datos móviles con salida
internacional solo para email. Este emula, en parte, el AP que brinda
internet en el parque de mi poblado.
- Una laptop DELL con dos mini tarjetas wifi, en la cual estoy
implementando mi AP con hostapd, dhcp y dns. Al final se conectará al
portal cautivo que ya mencioné pero por ahora solo al móvil de arriba
para compartir la conexión para email a modo de prueba, y así comprobar
que está trabajando ok.
- Una laptop Acer la cual actúa como cliente y que disfrutará de esa
conexión para email, y así comprobar que mi AP está trabajando bien.



Bien con la arquitectura para la prueba.
Si eso te funciona, bárbaro.
El tema, es que no sé cómo se comportará luego el portal cautivo.
Porque si está configurado por un "BOFH", el hijo de su madre podría  
haberlo configurado para que no entregue paquetes si el requerimiento de  
los mismos no proceden del mismo navegador identificado en el portal a

Tendrás que, y en orden:
1) Tomar la señal, e identificar tu máquina en el portal, mediante
"algo" que la mantenga enlazada a nivel de "root".
2) Crear un punto de acceso con hostapd (eso ya lo tienes hecho).
3) Crear un servidor DNS en tu máquina (eso también lo tienes más o

4) Crear reglas de iptables que enmascaren el tráfico (eso te lo

Re: Issue with notebook (maybe the battery?)

Hi, Joe.

 Checking the purchase invoices, I bought the notebook on September
 19, 2013, and then changed the battery on November 2, 2015. So
 less than two years ago I have this battery.

 The notebook I use it practically every day and I leave it
 sleeping from one day to the next so I do not have to open every
 application every time. I'm not sure if that impacts so much on
 the battery life.

I think he made that recommendation about disconnecting the charger when
the charge reaches 100% because he thought otherwise would affect the

Very interesting what you mention in these paragraphs. So in this case a
measurement on the battery would have to give a voltage between 3.0V and
4.1V per cell if the battery works correctly?

 But in any case, in all this time, whenever the battery was
 charged, the charge level was up to 100%. So just since yesterday
 I suddenly saw that the load stayed at 38% and I started to
 experience this issue.

Do you think the problem might be in the charger? At the beginning I had
thought that maybe not since the notebook works when it is connected.
Although perhaps it could be that if the electronics that manages the
phases that you mentioned before is physically in the charger, the
problem is in the charger.

Without seeing the command and output, we cannot check it.  But, if

Once you are confident your USB flash drive has a good image, try
booting it in your newest x86 computer.  If that fails, try other x86
computers.  If none of them boot, contact your vendor.


No, the image works, it has a problem bringing up the full graphical

option (it has both a 64 and 32b live parts) and are both jessie based.

Okay.



1.  Burn the ISO image to optical media and boot that.


Tough luck, the one machine has no such thing, the ill box has its cd

Many optical drives have a small hole in the front door that you can 
insert an unbent paper clip into to manually open the drawer.




2.  Download a memstick.img file that is meant to be burned to a USB

offer such, you might need to find a different tool.)


Again the question is not so much at the vendor's magic system but why
would a 0.6G image rent the rest of the disk useless for copying stuff

isohybrid images have non-standard on-disk data structures to get them 
to boot when burned to CD and when burned to USB; basically, they are 
hacks that "mostly work".  You're not going to get meaningful results 
with gparted, fdisk, parted, or the others.

The HOWTO looks fine for 2010. In 2017 CUPS has changed but, more
importantly for this thread and its sister one at

 https://lists.debian.org/debian-user/2017/03/msg00100.html ,

Samsung has made changes to its Unified Linux Driver package.

rastertosamsungspl doesn't exist anymore. It is now rastertospl; the
PPDS are altered to reflect this.

It is a good object lesson in not using outdated proprietry software.

The output should be at least a screenful of text. Do you still get your
previous output with

 cupsfilter -p /etc/cups/ppd/Samsung_ML-191x_252x_Series.ppd -m printer/foo 
/etc/nsswitch -e > out.prn ?

That is, don't direct the error output to a file but to the screen.

How about

 cupsfilter /etc/nsswitch > out.prn ?

That should give more than one line of output.

(Unable to determine MIME type of "/etc/nsswitch" is perturbing).

I downloaded the file from the above URL, and copied it as root to

That's for binary key files. This one is ascii armoured, so it needs an

Which is worse than it was before, it is now complaining about more keys.


Let's try the proper extension first and see what that fixes.

What do you mean?  A generator or an alternator?  Given enough power
from mechanical source (wind) to overpower the resistance of the
generator it would produce current.  Most of them, except for brush
dynamos, will produce AC which needs to be rectified back to DC and
regulated at a current a little above that of the battery.  Whether it
is a bicycle or wind generator or your auto/moto charging circuit, isn't
it how it all works?
Now if you put a 3' fan in a truck alternator and a 100Amph battery I
suspect it would take a hurricane to get it moving.

> He didn't get electrocuted or anything, the fan abruptly stops turning.

This all started from the OP stating that FMIT (on all debian main
rep's) records sound without any audio inputs in the system.

Careful you're agreeing with me.
I and my classmates actually learned 1st semester calculus in 2nd 
semester physics - ie springs and pendulums.
There was Part II of my story. Second semester sophomore year all 
engineers and some math majors took a specific Differential Equations 
course. It was taught in a different format - 3 lectures and 1 
recitation each week. As the number of students required two lecturers 
and the students were equally divided, one lecture was from engineering 
and one from the math faculty. Students were randomly assigned, the 
lectures being in the same hour. The math professor was a pure 
mathematician {found out later that math grad students competed to take 
his classes}. The rumor at semester's end was that the engineering 
professors students' grade distribution was a very normal bell curve. 
The math professor's distribution was doubled humped. The engineering 
students average being ~10 points lower.





If you're less terminant next time, I'll provide again examples ;-)

Update -- it *almost* worked. I now have a clean flash drive with the 
right partition type and file system, which I get the right permissions 
to everywhere, including in Files, when it is mounted. BUT it still is 
not auto-detecting when I plug it in.

In Disks, I notice the following:

Even before I do anything, when neither working nor almost-working 
drives are plugged in, Disks shows me an entry for one of the USB flash 
drives.

If I plug in the almost-working one, it occupies that entry and 
populates it with information. If I plug in the working one, a new item 
is created for it. If I unmount and remove both usb drives, one of the 
two entries disappears and the other one doesn't.

Comparing the two with the drives plugged in and mounted, they look 
extremely similar, except for the following. In the working one: 

Model: hp v250x (1100)
Size: 8.1GB (8,103,395,328 bytes)
Partitioning: Master Boot Record
Serial Number: 

In the almost-working one:

No, the question is posed in such a way that the OP can slap you down
when you answer it in your way as opposed to the OP's required way.
It took 6 minutes for Peter Ludikovsky to fall into the trap, and
a further 19 minutes for the rude response, "Peter Ludikovsky wrote
without useful content:".

Or, as Curt wrote in

"And anyway, it's obvious Dick Owlett is crowdsourcing his retirement,

Note that you can change the partition type with a partition editor.
It's just the value of a specific byte in the partition table with
no further effects whatsoever (excluding some gullible desktop
environments, but those believe in file endings too, snark, snark ;)

So no need to reformat (not telling you what to do, but if you're
still in investigative mood, this would be a candidate).

Sorry, richard: no web page, but perhaps something to start:

True, but 
my learning style is often dependent on examples more than definitions.

I learned that as a freshman engineering student in Fall 1961.
Only engineers and declared math majors took a specific calculus 
sequence. Our Teaching Assistant was a first semester grad student. His 
specialization was *PURE* mathematics. Our section [one of > 20] had 20 
engineers and 2 math majors. He lectured rigorously on the theory. On 
the first of 3 course-wide exams we set some sort of record for the 
lowest class average [even the 2 math majors acing the exam didn't 
help;]. During a post-mortem, he asked for suggestions. The engineers 
replied "Give us examples!" He replied that's now to teach math, you 
need theory. We all but chanted "Give us examples!" He partially 
partially caved saying "Till the next exam. Then we'll go back to the 
right way [implication of lots of remedial homework]."

The next exam had us not at the top, but having a respectable class average.





You can move to other places with "cd" and ask where you
are currently with "pwd" or "echo $CWD", but your home
stays at "/home/richard" -- or wherever it is.


http://www.ee.surrey.ac.uk/Teaching/Unix/unix1.html
http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html

Sections 1.4, 1.6 part 2, and 2.1 demonstrate use of '.' and '~' to
represent directory names.

To the best of my knowledge, '.' is intrinsic to the filesystem


Yes and no (see below)


design, whereas expansion of '~' is handled by your shell.


Yes. The shell expands ~ to your current *home* directory (and it
expands ~foo to foo's home directory).

Now to the "yes and no": yes: every directory has two entries: ".",
which resolves to the directory itself, and "..", which resolves
to the directory's parent. This is the "intrinsic" part, i.e.
the "yes" part.

To the "no" part: in the shell, names of files are often resolved
using some default mechanism. If you invoke a command, then (unless
it's a shell builtin), the shell looks for this command as an
executable in one of the directories listed in the shell environment
variable PATH. Unless you give an explicit directory, as in
"foo/command", where the shell would look in directory foo (relative
to the current working directory, CWD [1]). Thus, ./command would
look in the current working directory.


I hope someone else here will correct or elaborate that statement if necessary.


So yes, correct, but some further explanation might help in
understanding how to use it in a shell.

regards

[1] Of course, if you start your path with /, it's an absolute
   path, like /usr/local/bin/foo/command.

Umm, openjpeg has also been removed from Stretch/Testing and Unstable

Multimedia problem (Qt5)

[Edward Park]

I have Debian Jessie 8.7 installed. I can play audio and video files fine
with the default GNOME MPlayer. However, when trying to use
*QMediaPlayer* class
with Qt, the moment I run my resulting program it logs me out! As in my
account I used to login on startup. On the Qt forum I have asked for help
and tried many ways. In the end it was determined it wasn't a Qt problem.
It is a Debian problem. I also tried playing a video file with the
command *gst-play-1.0
name.mp4*. Same thing: logged me out. I tried everything I could with Qt
with tons of people's help. So, I am here asking you Debian folks.

Output from *sudo dmesg* 

Also, if anyone is wondering where I asked for help for Qt, *here*
.

Thanks a lot!

I honked my mouse up into the top left corner of the screen, as you do 
in Gnome, and typed "disks" in the search box. And, to quote General 
Melchett, "Well bugger me with a fishfork" if there wasn't an application

(there was, so no need to... anyway)

It reports that my correctly working disk has a partition type of 83

Buen día amigo, y agradezco mucho que me hayas respondido.

Respondiendo tus preguntas te digo que todo lo que pretendo hacer es
crear un AP en mi laptop DELL con debian 7 para compartir la internet
'pública' que existe acá en el parque de mi pueblo.

La conexión es abierta, bueno hasta el punto de acceso wifi. Puedes
traer cualquier laptop o móvil y basta con seleccionar el AP de la
empresa de telefonía, ahora para navegar, tienes que levantar el
navegador y entrar un usuario/contraseña de una cuenta ya sea permanente
o temporal pero hay que autentificarse.

Y para configurar mi sistema en casa estoy empleando un móvil samsung
con un zona wifi(AP) y datos móviles activados que imita lared wifi del
parque. Luego mi laptop DELL donde estoy implementando mi AP wifi para
compartir la internet del parque, y... otra laptop Acer que actúa como
cliente para disfrutar de la conexión que quiero compartir.

Esta es mi configuración. Por qué hago esto? Bueno, cada cliente que
viene al parque para conectarse a internet tiene que tener una cuenta,
ya sea permanente o temporal, y con mi sistema podríamos conectar a
varios clientes, a través de mi AP y con una única cuenta.

Me entiendes ahora?  :)

Ahora entiendo.
Estás entrando mediante un Portal Cautivo.


Bueno, al final... conectaré mi AP a un portal cautivo -que es donde
existe internet, en el parque del pueblo- y obviamente tendré que
hacerle ajustes pero ahora estoy trabajando en mi casa y para emular el
entorno y poner a punto el sistema tengo:

- Un móvil con zona wifi y conexión por datos móviles con salida
internacional solo para email. Este emula, en parte, el AP que brinda
internet en el parque de mi poblado.
- Una laptop DELL con dos mini tarjetas wifi, en la cual estoy
implementando mi AP con hostapd, dhcp y dns. Al final se conectará al
portal cautivo que ya mencioné pero por ahora solo al móvil de arriba
para compartir la conexión para email a modo de prueba, y así comprobar
que está trabajando ok.
- Una laptop Acer la cual actúa como cliente y que disfrutará de esa
conexión para email, y así comprobar que mi AP está trabajando bien.



Bien con la arquitectura para la prueba.
Si eso te funciona, bárbaro.
El tema, es que no sé cómo se comportará luego el portal cautivo.
Porque si está configurado por un "BOFH", el hijo de su madre podría 
haberlo configurado para que no entregue paquetes si el requerimiento de 
los mismos no proceden del mismo navegador identificado en el portal a 
través de "cookies".




Eso, es harina de otro costal.
Es lo más complicado para saltear en cuanto a restricciones.
No podés hacer un puente (bridging).


Si he podido lograr un puente entre eth0 y wlan0 pero no entre wlan0 y
wlan2 pero... la conexión no la recibo por cable sino mediante wifi.


Eso debería ser transparente al tipo de placa que se use.
Una placa es una placa, en forma independiente de si es ethernet, wifi o 
telefónica.




Tendrás que, y en orden:
1) Tomar la señal, e identificar tu máquina en el portal, mediante
"algo" que la mantenga enlazada a nivel de "root".
2) Crear un punto de acceso con hostapd (eso ya lo tienes hecho).
3) Crear un servidor DNS en tu máquina (eso también lo tienes más o
menos hecho).
4) Crear reglas de iptables que enmascaren el tráfico (eso te lo mandé).

La pregunta del millón: ¿cuál es el portal cautivo?


Primero quiero lograr que mi AP trabaje en el entorno que tengo en casa,
es más cómodo y más sencillo y después deberé hacer los cambios para
conectarlo a ese portal cautivo.


Buen plan de trabajo.

Thank you, the first reference was the key.
I also is a useful illustration of why my original post said:
"

The author of that page made only *3* assumptions:
   1. that the reader was interested.
   2. that the reader's literacy level was adequate.
   3. that the author knew he knew *nothing* about the reader's

It wasn't so much the author's descriptions, but his use of a

Saludos a todos,

Estoy retomando un tema que tengo pendiente desde hace algún tiempo
porque aun no lo he logrado poner en marcha. Me refiero a la
implementación de un AP wifi en una laptop DELL a la cual le he
instalado dos mini tarjetas wifi, wlan0 y wlan2.

Hasta donde he llegado he logrado que el AP montado sobre wlan0 conecte
a otros dispositivos móviles y también que la laptop se conecte a la
red(un móvil con zona wifi y datos móviles activados) mediante wlan2,
pero parece que tengo problemas con el enrutamiento ip desde wlan0 y
wlan2 en la propia laptop pues los móviles que se conectan al AP de la
laptop no logran navegar. Desde la laptop si puedo navegar, pero desde
los móviles conectados al AP de la laptop no logro navegar.

La ip del móvil con zona wifi y datos móviles activados es 192.168.43.1,
y la laptop toma la 192.168.43.156. Luego, el AP de la laptop tiene la
ip fija 192.168.42.1 y asigna bien ips al resto de móviles que se  
conectan.


Repito. Desde la laptop puedo navegar correctamente pero desde los
móviles conectados a ella no logro navegar.

Muestro la condiguración que he heco por si algún experto pueda
mostrarme el error que estoy comentiendo.

1) Configurando el adaptador wifi(wlan0) con ip estática.

/etc/network/interfaces
allow-hostplug wlan0
iface wlan0 inet static
address 192.168.42.1
netmask 255.255.255.1

2) Instalación y conf del server DHCP.

apt-get install isc-dhcp-server

/etc/dhcp/dhcpd.conf
# option domain-name
# option domain-name-server
authoritative;

subnet 192.168.42.0 netmask 255.255.255.0 {

default-lease-time 600;
max-lease-time 7200;
option domain-name "local";
option domain-name-servers 8.8.8.8, 8.8.4.4;
}

En /etc/default/isc-dhcp-server
DHCP_CONF=/etc/dhcp/dhcpd.conf
INTERFACES="wlan0"

3) Instalar y conf de hostapd.

interfaces=wlan0
driver=nl80211
ssid=test
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
#wpa=2 #todo lo que sigue si pongo contraseña al AP
#wpa_passphrase=secret
#wpa_key_mgmt=WPA-PSK
#wpa_pairwise=TKIP
#rsn_pairwise=CCMP

En /etc/default/hostapd
DAEMON_CONF="/etc/hostapd/hostapd.conf"

4) Configurando el enrutamiento IP entre wlan0 y wlan2.

En /etc/sysctl.conf
net.ipv4.ip_forward=1

ejecutar,

sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

Para implementar un router en el AP, ejecutar,

iptables -t nat -A POSTROUTING -o wlan2 -j MASQUERADE
iptables -A FORWARD -i wlan2 -o wlan0 -m state --state
RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wlan0 -o wlan2 -j ACCEPT

Para salvar las tablas de ruteo en /etc/iptables.ipv4.nat, ejecutar,

sh -c "iptables-save > /etc/iptables.ipv4.nat"

Adicionar, al final del fichero /etc/network/interfaces, lo siguiente
para restaurar las tablas de ruteo cuando se inicia el AP.

pre-up iptables-restore < /etc/iptables.ipv4.nat

HASTA AQUI

A mi juicio, el problema lo tengo en las sentencias de iptables.

Este procedimiento lo he tomado desde un tutorial que encontré, en cual
se enrutaba desde eth0 hasta wlan0 y yo lo ajusté sustituyendo eth0 por
wlan2 pues tengo dos mini tarjeta wifi instaladas.

Anticipadamente, reciban mis agradecimientos.


Te estás complicando la vida en extremo, y estás cargando cosara "raras"  
en las

direcciones de red

Si no tienes una restricción de acceso a la red en wlan2, ya sea por  
MAC, nombre
de dominio o alguna otra cosa, y que pueda servir como servidora DNS y  
DHCP a
cualquier conexión, lo que debes hacer es un puente:  
https://wiki.debian.org/es/Compartir_red_fisica_con_WiFi


Ahora bien, si el proveedor de red te ha puesto trabas, debes  
configurarte como

servidor y enmascarar todo a través de tu computadora.

#/etc/network/interfaces

QUIERAS PONER
option routers 192.168.42.1;
}


#/etc/default/isc-dhcp-server

hostapd está bien.

Ahora, no te embrolles tanto con iptables.

Edita (o crea) el archivo /etc/rc.local

#!/bin/sh -e

I made some tries with different configurations and I found it works
normally removing the lines "user" and "groups" from the configuration

Is it right/normal?

Respondiendo tus preguntas te digo que todo lo que pretendo hacer es

La conexión es abierta, bueno hasta el punto de acceso wifi. Puedes
traer cualquier laptop o móvil y basta con seleccionar el AP de la
empresa de telefonía, ahora para navegar, tienes que levantar el

Y para configurar mi sistema en casa estoy empleando un móvil samsung
con un zona wifi(AP) y datos móviles activados que imita lared wifi del

compartir la internet del parque, y... otra laptop Acer que actúa como
cliente para disfrutar de la conexión que quiero compartir.

Esta es mi configuración. Por qué hago esto? Bueno, cada cliente que
viene al parque para conectarse a internet tiene que tener una cuenta,
ya sea permanente o temporal, y con mi sistema podríamos conectar a
varios clientes, a través de mi AP y con una única cuenta.

Bueno, al final... conectaré mi AP a un portal cautivo -que es donde  
existe internet, en el parque del pueblo- y obviamente tendré que hacerle  
ajustes pero ahora estoy trabajando en mi casa y para emular el entorno y  
poner a punto el sistema tengo:


- Un móvil con zona wifi y conexión por datos móviles con salida  
internacional solo para email. Este emula, en parte, el AP que brinda  
internet en el parque de mi poblado.
- Una laptop DELL con dos mini tarjetas wifi, en la cual estoy  
implementando mi AP con hostapd, dhcp y dns. Al final se conectará al  
portal cautivo que ya mencioné pero por ahora solo al móvil de arriba para  
compartir la conexión para email a modo de prueba, y así comprobar que  
está trabajando ok.
- Una laptop Acer la cual actúa como cliente y que disfrutará de esa  
conexión para email, y así comprobar que mi AP está trabajando bien.



Eso, es harina de otro costal.
Es lo más complicado para saltear en cuanto a restricciones.
No podés hacer un puente (bridging).


Si he podido lograr un puente entre eth0 y wlan0 pero no entre wlan0 y

Tendrás que, y en orden:
1) Tomar la señal, e identificar tu máquina en el portal, mediante  
"algo" que la mantenga enlazada a nivel de "root".

2) Crear un punto de acceso con hostapd (eso ya lo tienes hecho).
3) Crear un servidor DNS en tu máquina (eso también lo tienes más o  
menos hecho).

4) Crear reglas de iptables que enmascaren el tráfico (eso te lo mandé).

La pregunta del millón: ¿cuál es el portal cautivo?


Primero quiero lograr que mi AP trabaje en el entorno que tengo en casa,  
es más cómodo y más sencillo y después deberé hacer los cambios para  
conectarlo a ese portal cautivo.

I think I tried lftp in my experiments, and it was lacking in some minor

last one I tried; I don't recall now.

This "Systems Management" appliance from KACE, then bought by Dell, then
bought by Quest, is marketed as the gee-whiz solution to managing hundreds
or thousands of network-attached devices (Windows PCs, Macs, Linux PCs,
tablets, etc) from an administrative standpoint. So far, after wrestling
with it for nearly a year, I'm not impressed.

For example, there is no sftp access, only ftp. (And so far, after trying
for a week, I've been unable to get it to work as how the documentation
describes. There's no way to set the ftp user (it's built-in; can't find
any configuration for it anywhere), and the only real options for ftp are
"on/off" and "writable" or not; I've set the check-box to "writable", but
so far, it ain't. Pfft. As I said, not impressed And the documentation?
And the support options? As I said, not impressed.)

The device size is not determined by the image data which get written to it.
I assume that firmwares and operating systems obtain it by SCSI commands
from the stick hardware.

The device file in Linux is simply a string of the determined number
of blocks.

The partition tables are simply data written to those blocks.
Their block addresses and the meaning of their bytes is subject to
conventions of software producers.

I understand Microsoft and IBM specified the MBR partition table.
Later Intel specified EFI and GUID Partition Table (GPT) as replacement
of BIOS and MBR partition table.
Apple had its own Apple Partition Map. Sun has disklabels. SGI had MIPS
Volume Headers. FreeBSD installs its slices inside MBR partitions.

Sorry, richard: no web page, but perhaps something to start:

  ./ means "HERE"
  ~/ means "HOME"

You can move to other places with "cd" and ask where you
are currently with "pwd" or "echo $CWD", but your home
stays at "/home/richard" -- or wherever it is.

Yes and no (see below)

Yes. The shell expands ~ to your current *home* directory (and it
expands ~foo to foo's home directory).

Now to the "yes and no": yes: every directory has two entries: ".",
which resolves to the directory itself, and "..", which resolves
to the directory's parent. This is the "intrinsic" part, i.e.
the "yes" part.

To the "no" part: in the shell, names of files are often resolved
using some default mechanism. If you invoke a command, then (unless
it's a shell builtin), the shell looks for this command as an
executable in one of the directories listed in the shell environment
variable PATH. Unless you give an explicit directory, as in
"foo/command", where the shell would look in directory foo (relative
to the current working directory, CWD [1]). Thus, ./command would
look in the current working directory.

So yes, correct, but some further explanation might help in
understanding how to use it in a shell.

When you write a disk-image onto a "disk" (in this case, a USB mass
storage device), you are overwriting all of the metadata at the start
of the "disk", including the partition table.  If the disk-image came
from a 4 GB disk, and you write it onto an 8 GB disk, then the 8 GB
disk will *believe* that it is a 4 GB disk, because it has the metadata
from a 4 GB disk.

As others have said, this has absolutely nothing to do with the bs=
option in dd.  All that does is make the dd command run a tiny bit
faster or slower.

Hi,

my hand made partition 3 fell victim to the deceptions of nested
partitions. It starts inside the ISO after the end of partition 2.
It should of course start after the end of partition 1.

So this is not the right start of partition 3:

To me this is not an unexpected result.  I don't remember the details, but, 
depending on how you copy the install image to the disk, it will make the disk 
(even a much larger disk) look like it can hold only the installation disk.  

IIRC, it has to do with how many partitions you have on the disk and where you 
copy the image to--again, iirc, if you partition the disk first, and then put 
the image in one partition, it will fill only that partition.  If you put the 
image on the entire disk, it will fill the entire disk.

In your copying / dding / whatever of the image to the disk, (again, iirc) if 
you specify, for example, the target as /dev/sdc the entire disk is filled, if 
you specify /dev/sdc1, you fill only partition 1.

Whether you can then boot the image is another question.  I don't remember 
enough to give more details atm.

Hardly. Unless it is an operating-system-on-a-stick.

The habit on the storage sector is to count by SI compliant mega and

(Well, you can be lucky if it is not a fake stick which maps more than

It is most probably a problem with the partition tables in the ISO.

  wget 
'https://downloads.sourceforge.net/project/rescatux/rescatux_0_40_b11/rescatux-0.40b11.iso'

  xorriso -indev rescatux-0.40b11.iso -report_system_area plain

shows the same "mjg" layout as Debian installation ISOs:

- MBR partition table with nested partitions (some partition editors
  hate this).

- GPT partition table not properly announced by "Protective MBR" and
  with nested partitions (doubly hated).

- APM partition table with block size 2048 (look here for a suspect !)

This collection of little sins and contradictions is enough reason for
any partition editor to bail out.
We should reduce the list to the MBR nested partition sin.


> I am trying to use the empty part of the stick to copy and store
> temporatily some important files

Well understood.

You should clean out the surplus partition table headers

  iso=/dev/sdb

  # Remove GPT header block.
  # I add option conv=notrunc for the case this is done with a image file
  # rather than a device file. It prevents truncation of the file.

  dd if=/dev/zero conv=notrunc bs=512 seek=1 count=1 of="$iso"

  # Overwrite APM Block0 signature by unchanged isohybrid MBR start
  # provided by Debian package "isolinux" since oldstable Debian.
  #
  # We want these bytes, and isohdpfx.bin is their cheapest source:
  #  33  ed  90  90  90  90  90  90  90  90  90  90  90  90  90  90
  #  90  90  90  90  90  90  90  90  90  90  90  90  90  90  90  90

  dd if=/usr/lib/ISOLINUX/isohdpfx.bin conv=notrunc bs=1 count=32 of="$iso"

Then try to find a partition editor which tolerates the nested
MBR partitions.


Last resort:
If no partition editor is willing to work, we could patch some numbers
into MBR partition slot 3 to make us a partition by hand. These bytes:
  00 ff ff ff 83 ff ff ff bc d0 13 00 44 2f d3 00
at byte position 478 would do this trick:
  Device Boot   Start  End  Sectors  Size Id Type
  test.iso1  * 64  1374207  1374144  671M  0 Empty
  test.iso2   1297212  1298619 1408  704K ef EFI (FAT-12/16/32)

Because xorriso built it according to the BIOS+EFI isohybrid layout
as developed by Matthew Garrett (mjg) in 2010.

Rescatux people used something named
  LIVE-BUILD 5.0_A11-1; HTTP://LIVE-SYSTEMS.ORG/DEVEL/LIVE-BUILD
which obviously ran xorriso.
This layout with several partition tables shall boot on as many
BIOSes and EFIs as possible.
Usefulness for partition editors is only a secondary consideration.


> So fdisk uses things differently than gdisk, or is the one using the other?

Yes. They are different programs.
fdisk is mainly for MBR partition tables, gdisk is mainly for GPT.
Since i propose to remove the not-so-good GPT and APM, fdisk should
be your first try afterwards.


> The EFI part is sdb2, right?  Which resides inside sdb1?

sdb1 makes the whole ISO filesystem mountable.
It has partition type 0x00 (= "Empty") because else EFI would refuse
to accept the partition of type 0xef (= "EFI") which sits inside sdb1.

Good question.

Hardly any partition editor really helps to clean up the mess.
So, yes, it is quite normal that adding a partition to mjg's partition
table equipment is cumbersome.

I made some effort in the recent years to enable a less tangled layout
based solely on MBR partitions, with the EFI boot image outside the
ISO so that there emerge no nested partitions.

grub-mkrescue on the other hand offers a partition-editor-friendly
layout based entirely on GPT (if no appleisms are configured to go
into the ISO). The ISO itself is not mountable by a partition then.

But understandably, the distros are not very eager to make experiments
with their ISOs, which on the first hand shall boot and not be nice
to partition

space ob the disk/mem-stick

I have done this 3 times bs=4M bs=1M and without a bs= tag, no difference!

No, the image works, it has a problem bringing up the full graphical
part on a an old pc with very little RAM and video memory on its 586
option (it has both a 64 and 32b live parts) and are both jessie based.
The debian 32bit 8,7,1 works fine on the sane machine

Tough luck, the one machine has no such thing, the ill box has its cd
player jammed shut with a CD in it from 13 years ago that plays fine on
live jessie

Again the question is not so much at the vendor's magic system but why
would a 0.6G image rent the rest of the disk useless for copying stuff
in and out, which I have done with many live systems.

On Debian the PPD is in the printer-driver-escpr package, The -P option
isn't needed. -m escpr:0/model. would be used instead.

The user's username and password can be used if she is a member of the

Esta es mi configuración. Por qué hago esto? Bueno, cada cliente que
viene al parque para conectarse a internet tiene que tener una cuenta,

varios clientes, a través de mi AP y con una única cuenta.

lftp is also worth a look.  If you're an experienced Unix shell user,
lftp is almost ridiculously intuitive.  (That said, I haven't seriously

I know a chap who found about that the hard way when he tried to get

turned by having a fan connected to it. :)

He didn't get electrocuted or anything, the fan abruptly stops turning.

Re: openvpn - Não consigo acessar maquinas clientes

[Leandro de Lima Camargo]

E a sua máquina na matriz, está nessa rede “atrás” da VPN (x.y.z.201)?
O IP x.y.z.219 no servidor é o IP público? Ou IP que faz comunicação com a rede 
interna?

Como eu te falei, se o traceroute para no servidor, o próximo salto já seria o 
micro destino que está na rede VPN.
Parece que o servidor encaminha o pacote a ele mas não tem retorno, e por isso 
não aparece no traceroute.
Como isso aconteceu após o reboot, pode ser que o servidor estava configurado 
para entregar rotas às máquinas clientes e perdeu essa configuração agora.

I suppose this is normal for an 8Gb usb stick. 249Mb go to firmware that

So where does the false alert come from on Gparted about the 2048b?
Is it a problem with the way I restore the iso, a problem with the iso
that Rescatux forces (I wouldn't think so) or a problem with the stick
itself?

why does this happen?  Again this is not an iso I created but downloaded

So fdisk uses things differently than gdisk, or is the one using the other?

The EFI part is sdb2, right?  Which resides inside sdb1?

So it is normal that if you write such an iso in a 64Gb stick 63Gb
remain useless as long as this system is on it?  Strange but still
