Hola a todos.
Soy muy nueva en lo que respecta a Debian, pero ya estuve metiéndole mano
en una máquina virtual.
Ahora quiero instalarlo en un segundo disco duro en mi pc. Es una Core 2
Duo, con 2 Gb de Ram. El primer disco tiene Win7 y otras particiones donde
guardo datos. El segundo disco es de 250Gb y está vacío.
He estado leyendo y muchos aconsejan instalar primero Win7 y luego Linux.
Quisiera, por favor, que me digan si esto es así y si tienen consejos para
darme.
Desde ya, muchas gracias.

Saludos cordiales,
Luciana.

Si lo vas a instalar en otro disco no vas a tener problemas, simplemente 
instalalo teniendo cuidado al seleccionar el disco para las particiones. 
Si esto te preocupa mucho, desenchufá el disco con windows y después 
cuando esté todo instalado volvés a enchufarlo y actualizar grub o lo 
que utilices para el arranque.

Saludos.

La incomodidad de ese tipo de instalación es que cada vez que quieras 
cambiar de sistema operativo vas a tener que entar a la configuración 
del BIOS y cambiar la prioridad de discos para que encuentre Debian en 
el disco secundario.

No, no, porque grub o lilo se ocupan de cargar el SO que elijas, a lo 
sumo entrás en la bios la primera vez para dejarle la prioridad al disco 
con Debian, ya después no hace falta entrar en la bios.

esa recomendación es porque windows no sabe convivir con otros SO,
entonces toma el arranque para el solo sin fijarse si hay otra cosa.
Debian se va a fijar (o /debería/ fijarse) si hay otro SO, encontrarlo
(windows en tu caso) y armar un menú para que elijas con cual arrancar
la computadora cuando la enciendas

 Desde ya, muchas gracias.

Si vas a instalar en un disco duro distinto del que tienes windows no vas 
a tener mayores problemas, tan sólo tienes que planificar de antemano la 
instalación (tamaño y cantidad de particiones que quieres, gestor de 
arranque...) y tener cuidado de seleccionar el disco duro correcto a la 
hora de crear las particiones para dejar intacto el disco duro donde 
tienes windows.

Otra cosa que tendrás que tener en cuenta es el disco duro con el que vas 
a iniciar el equipo, ya que si el principal es windows no vas a poder 
arrancar con debian salvo que hagas malabares, por lo que te recomendaría 
configurar la bios para indicarle que quieres iniciar con el disco duro 
donde vas a instalar debian y después configurar el gestor de arranque 
(GRUB2) para que te permita iniciar windows a conveniencia.

Cualquier duda que tengas, pregunta :-)

Aumentar la cantidad de TTYs por default de 16 a 32?

Hola Lista.

Sigo sin podes aumentar la cantidad máxima de TTYs conectadas al mismo 
tiempo.


Creo que son 16 (de 0 a 15), pero no comprendo como poder aumentar este 
límite.


El error que me da de momento es:

PTY allocation request failed on channel 0

Bueno, si alguien me puede tirar una pista porque viendo lo que google 
me arroja no encuentro solución!

Re: Instalar Debian en un segundo disco duro

Gracias Gonzalo por tu respuesta! Sabía que Win es acaparador y
egoísta, y que Debian me dejaría elegir.

Gracias Camaleón por semejante consejo! Ya iba a poner a Win como
primera opción y después ya me veía llorando sangre. Hoy haré la
instalación. Ya tengo los tamaños de particiones y demás, planeados.
Máquinas virtuales, un excelente invento!
Ahora mismo quito el html.

Gracias a todos por colaborarme. Un abrazo en recompensa.
Ya les contaré cómo salió todo. :o

Script para controlar si Modem Router actualizo IP de dyndns

2014-06-23 Thread adriancito


Buenas compañeros.

Les pregunto, alguien analizó la situación de instalar un script que 
cada cierto tiempo (1 hora por ejemplo) compare la IP pública con la IP 
registrada en DYNDNS y en caso de que no sean iguales me envie un 
mensaje o similar?


Estoy viendo que en ocasiones el modem router se reinicia y no me 
actualiza los datos en dyndns.


Muchas Gracias a todos!

 Hola a todos,

 Tengo PPTPD instalado y configurado sobre máquinas físicas en CentOS, Debian, 
 Raspbian, etc, y ningún problema...

 Sobre containers OpenVZ en PROXMOX he configurado Tinc VPN y, quitando que 
 hay que hacer algún retoquito para que el CT tenga acceso al interface Tun de 
 la máquina anfitriona, funcionan...

 Pero hoy he intentado activar una VPN PPTP sobre un CT con Debían, en un 
 PROXMOX, y no ha habido forma, el servicio arranca, pero no hay forma de 
 conectar un cliente contra él.

 ¿Sabe alguien si hay algún tipo de truco, o configuración especial, para 
 montar un PPTP Server en un CT OpenVZ en PROXMOX ?

Yo hice lo de darle permisos desde el anfitrión y demás. Me levantó
correctamente ppp0 (era una conexión forticlient de vpn) y me tiraba
bien. Lo único que no me permitía era la regla de iptables, no me
funcionaba...

iptables -t nat -A POSTROUTING -s 192.168.0.0/16 -o ppp0 -j MASQUERADE

Esto no me funcionaba y tuve que montarlo en un KVM en proxmox...Me
daba error de iptables de sintaxis, pero créeme, lo estaba poniendo
bien puesto que es la misma regla que uso ahora mismo en KVM.

Saludos.

usar sudo para errores en el arranque

2014-06-23 Thread Antonio Trujillo Carmona

Quisiera poder usar las claves de usuarios, no la de root, cuando se
produce un error durante el arranque (normalmente cuando falla el fsdk y
te pide la clave para abrir una sesión), como lo hace ubuntu que no
tiene clave de root conocida.
Pero la clave va a ser de usuarios validados por winbind, por lo que se
tendrá que usar la cache de este si no esta levantada la red.
¿Alguien sabe como analizar el tema?

Urgente. He sobreescrito en partición Windows

2014-06-23 Thread Rafael Cantos Villanueva


Buenas a todos

He tenido un pequeño incidente, y he instalado Linux sobre una partición 
con Windows. Bueno, el disco duro ha quedado con Linux solamente como 
arranque, aunque ahora hay una partición que dice que es desconocida, 
otra que dice que es EFI y otra que es Swap.
Es importantísimo recuperar Windoww..., al menos los datos. He visto un 
programa llamado testdisk que sirve para recuperar particiones, pero no 
entiendo muy bien todo lo que veo en las guías y tampoco he conseguido 
hacer nada.

¿Qué  puedo hacer?

Voy a suponer que Linux no se ha instalado sobre Windows...

Muchísimas gracias por vuestra ayuda.

Re: Script para controlar si Modem Router actualizo IP de dyndns

 Buenas compañeros.

 Les pregunto, alguien analizó la situación de instalar un script que cada
 cierto tiempo (1 hora por ejemplo) compare la IP pública con la IP
 registrada en DYNDNS y en caso de que no sean iguales me envie un mensaje o
 similar?

Puedes utilizar el paquete ddclient que funciona con dyndns (yo lo
estoy utilizando con dyndns) y modificar el script para que cuando
detecte que cambió la IP haga lo que necesitas además de hacer lo
propio de ddclient. Obviamente vas a tener que mantener a mano el
script cuando se actualice, o de lo contrario marcarlo en dselect para
que nunca se actualice

Saludos.

 Estoy viendo que en ocasiones el modem router se reinicia y no me actualiza
 los datos en dyndns.

 Muchas Gracias a todos!

Ugh :-(

 Bueno, el disco duro ha quedado con Linux solamente como 
 arranque, aunque ahora hay una partición que dice que es desconocida, 
 otra que dice que es EFI y otra que es Swap.

¿Y cómo tenías particionado Windows?

 Es importantísimo recuperar Windoww..., al menos los datos. He visto un 
 programa llamado testdisk que sirve para recuperar particiones, pero no 
 entiendo muy bien todo lo que veo en las guías y tampoco he conseguido 
 hacer nada.

TestDisk sirve para recuperar datos, archivos... un sistema completo lo 
dudo (de ahí la importancia de las copias de seguridad) pero quizá sí 
puedas recuperar algún archivo.

Es importante que NO inicies Linux, que hagas una copia del sistema 
completo (una imagen) y que trabajes con testdisk sobre esa copia y NUNCA 
sobre el disco duro original. Tendrás más detalles del procedimiento en 
la página de la utilidad.

 ¿Qué  puedo hacer?
 
 Voy a suponer que Linux no se ha instalado sobre Windows...

Hombre... eso es mucho suponer :-/

 Muchísimas gracias por vuestra ayuda.

¡Ánimo!

Rafa:

Nosotros usamos testdisk ya que, en la inmensa mayoría de los casos, nos
permite recuperar las particiones desaparecidas/formateadas. El
procedimiento está descrito claramente en:
http://www.cgsecurity.org/wiki/Data_Recovery_Examples#Recovery_of_reformatted_partition

Para ejecutarlo, te sugiero que arranques la computadora con un CD/USB
de rescate. SystemRescue ya trae instalado testdisk, pero también
podrías usar Debian LiveCD e instalar testdisk.

Si no estás familiarizado con el tema (particiones, sistemas de archivo,
geometría de disco, etc.), lo más sensato sería pedir ayuda a un
especialista en recuperación de datos de tu localidad.

Suerte.

En principio parece que esa configuración es posible.

 Pero la clave va a ser de usuarios validados por winbind, por lo que se
 tendrá que usar la cache de este si no esta levantada la red. ¿Alguien
 sabe como analizar el tema?

Tendrías dos escenarios/opciones:

1/ Levantar manualmente todos los servicios que necesite winbind para 
funcionar (red, samba, etc...)

2/ Configurar winbind para gestionar los inicios de sesión en modo offline

Cualquier error que te dé el inicio de sesión en ambos casos lo verás en

Estimada Luciana:

Se nota que sos nueva en la lista; mi primera recomendación: haz lo que 
Camaleón te diga ;)


Segundo, tomate tu tiempo y leé esto
http://debian-handbook.info/browse/es-ES/stable/sect.installation-steps.html
sobre todo el punto 4.2.13.1. Particionado guiado, pues vas a tener que 
usarlo para definir tus particiones en el segundo disco.

Como regla general, para tu instalación, yo sugeriría
que elijas el particionado guiado y Separated /home partition, y 
dejando a tu sistema que se arregle con dicha tarea.

Tema a tener en cuenta: presta atención a la identificación de tus discos.
Muy probablemente tu disco conectado al banco 0 (SATA0) sea el que tiene 
Windows. Éste seguramente se identificará como sda.

Tené cuidado al instalar Debian de hacerlo el EL OTRO disco.
El instalador en algún momento te preguntará dónde quieres instalar el 
gestor de arranque; dile que sí a la opción por defecto, que es el 
registro de arranque maestro. Hazlo sin miedo, pues automáticamente 
carga un menú donde podrás iniciar con Debian o Windows a voluntad.


En resumen: todas las opciones por defecto del instalador son las 
recomendadas; en el único lugar que hay que tener cuidado, es al 
seleccionar sobre qué disco instalar el sistema.

Re: Instalar Debian en un segundo disco duro‏

2014-06-23 Thread Martino Arroyo

Estimada Luciana, yo utilizaría ese 2º HD para guardar mis datos y en el 1º HD 
instalaria Win y las distribuciones de linux que tu desees. Te pongo de como yo 
lo tengo particionado, tengo otro disco (desenchufado físicamente) con datos:

/dev/sda1     win7 - 40 GB ntfs
/dev/sda2     intercambio entre linux y win -- 4 GB ntfs
/dev/sda3     extendida o lógica - 111 GB ext4
     /dev/sda5     /home  57 GB 
ext4
     /dev/sda9     libre para futuras instalaciones  30 GB ext4
                           
                           
           n                   n
     /dev/sda6     Ubuntu -- 10 GB ext4
     /dev/sda8     Debian --- 10 GB 
ext4
     /dev/sda7     linux-swap - 2 GB

Antes de nada con Gparted, desde un CD o USB live, construyo la tabla de 
particiones del HD. Si vas a instalar windows hazlo el primero y en una 
partición primaria, las de linux hazlo en partición lógica, así no ocupas las 4 
particiones primarias que como máximo te de deja un HD.

El grub y grub2 te dara la opción de elegir con que S.O. arrancar, ten en 
cuenta que el 1º S.O. de la lista será la ultima distribución que instales, 
esto luego se puede cambiar.

Comparto /home para todas las distribuciones linux, cada distribución con su 
usuario y contraseña (se crea una carpeta en /home por cada uno), así no se 
mezclan datos ni configuraciones, no la formatees (la /home) al instalar una 
nueva xdd. Si quieres pasar datos de una a otra, entras como root y ya .
Cada distribución en una / individual. Una única swap para todas.
Todo en ext4 las linux.

Saludos cordiales.

Yo obtengo la ip pública con lo siguiente (en algún momento busqué cómo 
hacerlo en internet):
IPADDRESS=$(/sbin/ifconfig pppoe-wan | sed -n 's/.*inet addr:\([^ 
]*\).*/\1/p')
Esto desde el router/modem y me envía un email si la ip es distinta a la 
última guardada.

Micrófono integrado y problemas.

2014-06-23 Thread Emmanuel Brenes


Buenas gente, espero todo ande bien.
Verán, me surgió la oportunidad de comprar unos audífonos con micrófono 
integrado, pero no funciona el micro, lo demás está en perfecto 
estado... he visto que quizá sea PulseAudio e intenté varias cosas, 
incluso con Alsa, pero nada. Instalé pavucontrol para cambiar 
configuraciones de PulseAudio pero tampoco... ¿alguien sabe qué podría ser?

Así es Henry, activé los micrófonos y demás, pero lo único que consigo

RE: Instalar Debian en un segundo disco duro

2014-06-23 Thread Martino Arroyo

Estimada Luciana, yo utilizaría ese 2º HD para guardar mis datos y en el 1º HD 
instalaria Win y las distribuciones de linux que tu desees. Te pongo de como yo 
lo tengo particionado, tengo otro disco (desenchufado físicamente) con datos:

/dev/sda1     win7 - 40 GB ntfs
/dev/sda2     intercambio entre linux y win -- 4 GB ntfs
/dev/sda3     extendida o lógica - 111 GB ext4
     /dev/sda5     /home  57 GB 
ext4
     /dev/sda9     libre para futuras instalaciones  30 GB ext4
                               
                               
           n                   n
     /dev/sda6     Ubuntu -- 10 GB ext4
     /dev/sda8     Debian --- 10 GB 
ext4
     /dev/sda7     linux-swap - 2 GB

Antes de nada con Gparted, desde un CD o USB live, construyo la tabla de 
particiones del HD. Si vas a instalar windows hazlo el primero y en una 
partición primaria, las de linux hazlo en partición lógica, así no ocupas las 4 
particiones primarias que como máximo te de deja un HD.

El grub y grub2 te dara la opción de elegir con que S.O. arrancar, ten en 
cuenta que el 1º S.O. de la lista será la ultima distribución que instales, 
esto luego se puede cambiar.

Comparto /home para todas las distribuciones linux, cada distribución con su 
usuario y contraseña (se crea una carpeta en /home por cada uno), así no se 
mezclan datos ni configuraciones, no la formatees (la /home) al instalar una 
nueva xdd. Si quieres pasar datos de una a otra, entras como root y ya .
Cada distribución en una / individual. Una única swap para todas.
Todo en ext4 las linux.

Saludos cordiales.

  Given what has already hapened within the thread, the above
  message to which I am responding, appears to be a troll.
 
  Requesting that you take a religious-type discussion (like a list's
  Reply To settings) to the OT list isn't trolling!
 
 If either you or he, had read what had aleardy passed in the thread,
 you and he would have seen that the matter had been dealt with,

I had read through the thread.  For reference it starts here:

  https://lists.debian.org/debian-user/2014/06/msg01192.html

And it was that message to which I replied.  wes kindly pointed to a
different thread of discussion which clarified things somewhat.
However that was a different thread and I had skipped over reading it.

 resulting in my making a request for change, to the people maintaining
 PINE/ALPINE, to allow the option of replying to a list, using the
 List-Post field value in message headers, which solution had been
 included in the previous postings in the thread.

Sorry but it was not clear to me in the thread that you were making an
enhancement request for the alpine package.

As a suggestion I doubt the alpine package maintainers are reading
this mailing list.  I haven't seen the maintainer's address here, that
I have noticed.  It it much better for enhancement requests if a
wishlist bug is filed against the package in the BTS.  That will get
the attention of the maintainer.  But unless someone actually steps
forward and does the work it still probably won't get done.  But at
least the effort will be documented in an easier to locate place.

Most work for enhancing is better done directly with the upstream
maintainers.  It is controversial how many patches should be
maintained downstream in Debian.  Some think many.  Some think none.
Many upstreams become upset if their software is modified.  Some
welcome it.  Therefore I think it is best to try to work with the
upstream project directly when possible to develop new features.

 I had not previously been aware of RFC2369, and so, the thread, with
 its responses before the trolls, had been constructive and
 educational, which, I believe is supposed to be the purpose of this
 mailing list.
 
 Gmail appears to not have provision for making Requests For Change,
 regarding the Gmail email facility, so I appear to not be able to make
 a Request For Change, to the Gmail people, which could solve the
 problem in using Gmail..

Google is rather notorious for being hard to reach on such things.

 I had posted what I had posted, regarding the abillity to reply to the
 list, solution had been posted and demonstrated, and, the matter had
 (I believe) been closed, insofar as the thread on this list, had been
 concerned.
 
 The subsequent messages posted by
 b...@proulx.com
 tomh0...@gmail.com
 lazyvi...@gmx.com
 were inflammatory, and, posted for the purpose of being inflammatory,
 making them trolls.

Two of those three certainly were not.  But somehow I think we are
using different definitions for an internet troll.  A troll is almost
always trying to increase noise in a newsgroup or mailing list by
stirring up trouble.

  http://en.wikipedia.org/wiki/Troll_(Internet)

The messages you are marking as trolling are trying to reduce noise on
this mailing list.  Because discussions of reply-to have historically
been very controversial topics.  We have been there many times.

 The thread had come to an end; it had the solution, and, the thread
 had died, and those people revived it, to create a zombie for evil
 purposes.

Let me formally apologize if I misunderstood your message.  My mistake
was reading your message and thinking you were asking for a
controversial change to the mailing list.  If past history is a
prediction that would have started a discussion hundreds of messages
long.  If I had understood that you were asking for an enhancement
request for a package I wouldn't have commented as I did.  Therefore
let me say that I am sorry if I offended you.  I am also sorry if I
extended a discussion that had concluded.  No evil was intended.

Please be careful directly calling people trolls however.  We try to
be a pleasant and welcoming place here on the mailing list.  But ad
hominem attacks never go well for anyone.  My advice is to avoid using
that perjorative directly against people.  It is too easy to take it
personally since personally is how it is directed.  Therefore my best
advice is to avoid it.  :-)

Re: dhclient changes IP address

Rainer Dorsch wrote:
 my fritz.box is a DSL router from AVM, which unfortunately does not give me 
 access to syslog.

Oh.  I didn't realize that.  The way you talked about it I thought it
was another Debian system.

 What I noticed is that 192.168.178.87 shows up without MAC address
 in the list of network devices of the fritz.box

That is almost certainly an important clue to the problem.

 I think I will try first to get support from AVM on that topic.

Good luck!  However I am pessimistic about support from companies.  In
general they like to sell you things but unless you are a notable
customer with deep pockets they tend not to want to spend time
supporting you.  Every vendor is unique however.

In general a dhcp server will always assign the same IP address to the
same client.  Everyone knows this is based upon the client ethernet
address.  But many people do not know this is also based upon the uid
the client offers.  (It might be client hostname.  I don't remember
and have no time to research the precise thing.)  If a client offers
different uids then the dhcp server is obligated to assign a different
IP address.  The idea was that a multiple booting system would have
different uids and wouldn't share the same IP address even though it
had the same ethernet hardware address.

Is it possible that your client is somehow producing a DHCP request
but using different client parameters with the different requests and
therefore receiving different IP assignments in return?  Since you are
getting different IP assignments and it must be for some reason then I
suspect this possible case.  Assuming that the dhcp server is
standards conforming.

Do you keep getting different IP assignments every day?

 If that is not successful, I will look in more detail into the
 tcpdumps (although since I have to take that on the client side,
 that might be difficult during the startup phase).

Note that dhcpdump can still be used on your client.  It would require
some patience but it would capture the exchange.  Easier than
wireshark and specific to the domain at hand.  It would be on my list
to try to capture what the differences are when getting the different
IP assignments.

First, a warning: I am basically trying to reinvent a wheel, only 
for

my pleasure and knowledge.


Good luck.  As you had already noticed, this wheel is going to have 
some

rough corners, and just using debootstrap is much easier.


Indeed. But I do this on my spare time, without any constraint or order 
from anyone, and since I consider this for pleasure, using debootstrap 
would be a little like using a cheat.
Of course, I know that I risk to generate noise here with that, but I 
think I was clear enough: I want fun and learn, not especially something 
which works out of the box.



Yesterday, I was experimenting with dpkg ( for my own fun, and to
learn things ), especially with the parameter --root which change
the targeted system. Or, to be more exact, to change the directories
where it tries to retrieve it's own informations ( /var/lib/dpkg ) 
and

where it tries to deploy stuff ( / ).


You can do this, but the directory you pass as --root argument 
better

have some standard utilities on it, since dpkg requires them.


Now you mention it, it's true that dpkg's man says it uses a chroot. 
And indeed since the new root does not have anything, it can't run a 
script... did not thought about that.



* dpkg depends on various packages ( on my testing current system ),
namely: libc6, tar, libselinux1, liblzma5, libbz2-1.0, zlib1g.


It also needs some programs from essential packages on which it does 
not
explicitly depend.  And the maintainer scripts will use those as 
well.


I did not read the debootstrap script enough to notice those tools.




When it comes to libc6, dpkg report an error of being unable to find
various scripts, like IIRC /var/lib/dpkg/tmp.ci/preinst ( in the
chrooted environment, so /mnt/var/lib/dpkg/tmp.ci/preinst ).


This could be because the interpreter for those scripts, typically
/bin/sh, is missing.  Note that the exec(3) family of functions 
return

ENOENT in that case which often confuses users.
Besides a shell for the maintainer scripts, dpkg needs some utilities
like rm(1) for proper operation.  It checks for those at startup, but
that does not work with the --root option.

Maybe this gives you some idea why debootstrap has been invented in 
the

first place.


As I said, it's mostly for playing and fun. I understand why 
debootstrap was made (automated things which are painful otherwise). 
Trying to reinvent the wheel, or to be more precise, to reproduce it's 
behavior in my case, is not a good thing and I do not do it: at work. 
But for learning and understanding, it is a nice way imho. And I take 
some fun when tinkering around egg and chicken problems.




Cheers,
   Sven

Re: Getting rights right

2014-06-23 Thread Diogene Laerce

Hi Bob,

First thank you for the detailed answer, you kind of preventively
answered to all my doubts or interrogations. :)

I try to set up a new line of security (files and network) as I just
changed country and instead of being in one mostly targeting others, I
am now in one mostly targeted by others. :D

 I have a strange behavior lately on my Deby. After a run of :
 chown user:user -R /home/user/Documents
 and :
 chmod 700 -R /home/user/Documents
 
 Unfortunately that command was a mistake.  That will set rwx for owner
 on all files unconditionally.  For directories that is fine.  But that
 is not correct for files.  Only executables and executable scripts
 should have the execute bit set upon them.
 
 What you wanted to set was:
 
   chmod -R u+rwX,go-rwx /home/user/Documents

I ran this command to restart the process :

 find /home/user/Documents -type f -exec chmod u+rw,go-rwx -R {} \;

and will make executable all following files according the needs.


 The capital 'X' is the trick.  The GNU chmod documentation on this says:
 
   27.2.4 Conditional Executability
   
 
   There is one more special type of symbolic permission: if you use `X'
   instead of `x', execute/search permission is affected only if the file
   is a directory or already had execute permission.
 
  For example, this mode:
 
a+X
 
   gives all users permission to search directories, or to execute files if
   anyone could execute them before.

Yeah I did see that in the man pages but I had too much files with
hazardous rights to trust this command.


 But wait!  There's more.

Be sure I'm not going anywhere. :D


 That is usually called UPG (User Private Group).
 chown user:user -R /home/user/Documents
 
 And so that group should belong to the user.  Most importantly that
 group should belong *solely* to the user.  No other users should be in
 that group.  Therefore the better thing to do is to keep the group
 permissions when removing other permissions.
 
   chmod -R o-rwx /home/user/Documents
 
 Then you don't need to do anything more.  That would correspond to a
 user umask 07 setting.  better set umask 07 or new files will be
 created with permissions you are trying to avoid.
 
 Personally I always use umask 02 and then only add extra protection
 to specific files and directories that I want.
 
 And of course all of this is only important if you are operating on a
 multiuser server that has other people logging into it as non-root.
 (Root does not matter in either case.  You can't protect yourself from
 root.)  If this is on your personal laptop and no one else logs in
 then none of this matters aand I would stick with the Debian UPG
 default along with the default umask 02.

After reading this, I actually found that :

umask and level of security : The umask command be used for setting
different security levels as follows:

umask value Security level  Effective permission (directory)
022 Permissive  755
026 Moderate751
027 Moderate750
077 Severe  700

in there :
http://www.cyberciti.biz/tips/understanding-linux-unix-umask-value-usage.html

And I was planning to set a severe security plan. Based on the
thinking that I have 3 computers (that only I use) to run behind a box
and that I thought wiser to set them to the maximum security first, find
out what they will exchange in second and then update the permissions
accordingly, as I have very little impact on the box security.

I then opted for the umask 077. I'm not sure if it's really justified
but it couldn't do no harm.. I guess. :)


 If you want to verify what chmod is doing the GNU chmod command has
 the -v extension.  It will echo print what it is doing while it is
 doing it.  Adding the -v would show helpful information.  For example:
 
   $ chmod -v -R 700 junk
   mode of `junk' retained as 0700 (rwx--)
   mode of `junk/junk2' retained as 0700 (rwx--)
   mode of `junk/junk2/file1' changed to 0700 (rwx--)

I always forget to use that functionality. ^^


 I run :
 find /home/user/Documents ! -perm 0700
 
 As Linux-fan correctly noted that skips files that match 0700
 exactly.  So that part is working correctly.  What didn't work was the
 chmod 700 part.  But that was good because that isn't want you want to
 do.
 
[...]
 I believe you must have a typo somewhere.  If you double check
 everything you will find it.  However!  As I explained you do not want
 to chmod 700 all of your files recursively.  That would be bad.  So
 take it as a good miss and don't do it again.

Strangely, it seems that using symbolic mode instead of octal solved my
issue : all files are treated and I have no random results anymore.

Very thanks for your lights again, any indicators are always
blinkwelcomed/blink. :)

The Debian installer can do it. Compare
http://www.texsoft.it/index.php?c=hardwarem=hw.storage.boot-raid-squeezel=it
which should be still similar in Debian 7. If you are new to RAID, also
simulate the case of disk failure and replacement.

The step ``Install GRUB to all disks'' is better described as

# dpkg-reconfigure grub-pc

Also, if you manually want to create a RAID 1 of two partitions use

# mdadm --create /dev/md0 --level=1 --raid-devices=2 \

apt-get issues with download speed and server access

2014-06-23 Thread Joel Rees

(Seems like I remember seeing a thread on this recently, but I don't
see it in the last week's posts.)

Last week, when the kernel update came down the pipe, most of the
packages had decent speed, but the kernel and some others were cut
down to about a fifth normal speed.

Yesterday or Saturday, when I ran apt-get update, I got server access
errors on wheezy, including backports and security. Ran apt-get clean
and the access errors went away.

Today, I get access errors again, and they go away after apt-get
clean. And all packages are downloading at about a fifth my max speed
from the provider.

I'm feeling a little paranoid about this. Should I just assume my
wan-side connection is getting saturated for some reason?

Which commands did you run as root, or su/sudo root?

I have sometimes, especially when moving files between systems where
the numeric uids are different, found myself doing a recursive chmod
or chown, and being unable to change permissions on some files because
of the user I was running as. Then, after the directory permissions
changed, being able to change them on a second pass.

Re: apt-get update: unnecessary use of disk space

Bob Proulx b...@proulx.com wrote:

 What do you mean when you say these blocks won't be free ...
 without defragmenting?  Please explain.  If you have references to
 share that explained the details that would be great.

Just think about this:
* HD original = 1000
* HD -5%. =  950

The -5% can _only_ be used by processes (eg: to write their
log files); so for users, until a part or the whole -5% is
released by re-tuning the disk, the HD will always looks 950.

Now, if you know an underlying mechanism that silently retrocede
place from these 5% to users, please tell me what it is.

Hence these blocks won't be free, as users only see a HD of 950.

And BTW, even root sees a HD of 950, not 1000 (but only root can
use the remaining 5% it doesn't see).
 
 Also as I understand it use of e2defrag is not recommended.  Using
[cut blurb]

This isn't the question, try not to be silly; I took the example
of defrag pgm to illustrate the fact that the reserved 5% can
only be accessed by such a program, enforcing the fact that these
5% are _unreachable_ from anyone (except root in particular cases).

As either you wanna argue for looong sterile threads or you didn't
understood, I put it in short terms:
* HD (formatted) is 1000 (without any reservation)
* Regular 5% reservation drops its capacity to 950
* Everybody only sees and uses 950, not 1000
* The 5% resa will _never_ be available to users

Conclusion: users see and use a 950 HD, meaning if I/O
slows down when HD is 95% full, it will slow down at:
950 (HD seen capacity) * 95% = 902.5

If you chose lxde, you install without recommends.  That is easy with
aptitude and apt-gey can do that via command line.  Read the manual

 The whole reason I'm switching from Xubuntu to Debian is to get away

I don't know if it is the reason but the recalcitrant files were mostly

Hi Joel,

I don't know whether this relates to what you're saying, but a few days
ago debian.org was down, and xubuntu.org was *incredibly* slow, both on
my side and at http://www.isup.me, which told me both were flat out
down. I just went to sleep, and upon waking the next day, both were
doing well.

Also, a couple days ago, using the Debian Wheezy 64bit network install,
the debian.org default mirror didn't work, so I switched to the rit.edu
mirror and it worked perfectly.

I don't know if any conclusions can be drawn from my anecdotes, but if
you collect enough anecdotes perhaps it can help you figure out what's
going wrong.

Progress on my new Debian box

Hi all,

I've got the hardware all set up. AMD dual core 4100, 16GB RAM, 240GB
SSD for /, 750GB Western Digital Black for /var, /tmp, /run, and swap
partition, and a 3GB Western Digital Green for all my data.

I installed Debian Wheezy 7.5 network install with nonfree yes, and
xxxterm (soon to be called xombrero) plays Youtube videos perfectly.
Xfce right now, dwm later. I have UMENU and VimOutliner working
perfectly. Gnumeric and LyX are installed, although I haven't tested
them extensively.

The biggest problem I'm having right now is email. I set up a
preliminary Dovecot on the Debian machine. For some reason, the only
way to get the dovecot executable on Wheezy is to follow these
instructions on adding to your sources list:

http://wiki2.dovecot.org/HowTo/DebianStable

Then, so far, I can't access my new dovecot from my Debian machine,
although I can access it over the wire from my Ubuntu machine.
Thickening the plot even more is that nmap 192.168.100.4 from
192.168.100.4 won't read any open ports, even though the same command
issued from 192.168.100.2 shows 22, 80, 111, 143 and 993 open. I
suspect some sort of firewall issue, although at present I don't know
enough to prove or disprove that.

Anyway, things are going well. My other observation is that Debian is
less like Ubuntu than it initially looks.

Manufacturers (or researchers) don't work very much on this
specific point, which is too bad; imagine a new generation

My guess is that it already exists in labs, but will never

Yes, I should clarify. The following is the contents of my mount
command:

http://paste.debian.net/106401

The one with a UUID device, mounted to /, is really /dev/sda, the
SSD. /dev/sdb is the 3TB WD green for my data, and /dev/sdc is the 750GB
WD black, which is faster than the green, is for the changing part of
the OS and for my swap partition.

The idea was that I rely on my own discipline not to put any frequently
changing stuff on /dev/sda.

By the way, the following command shows that my SSD supports trim:

hdparm -I | grep -i trim

And so I can use the following command every once in a while to put no
longer used disk sections back in the pool:

fstrim -v /

Like mentioned in a previous message, on this box I went cheap rather
than going full-featured, so I anticipate using it only 2 years. I hope
the next one has 64GB RAM, and I hope by that time SSD storage is a lot
cheaper and more forgiving of a lot of writes.

Lots of conclusions can be drawn from anecdotal evidence but a proven

there is a verifiable, repeatable framework to return to. Anecdotal
evidence has a habit of morphing over time, which, amongst other things,
makes it useless for figuring out anything.

I believe that would be true of quite /old/ SSD drives, but definitely

hit that problem will take just as long as a traditional spinning drive
-- they too have limits, spinning drives are mechanical.

There have been very heavy torture tests on thew newer range of SSDs and
they are performing exceptionally well with mega data being written [1],
up to fairly heavy data usage levels.

There is apparently a way to restore SSD drives to original condition by
super heating the layer that breaks down (due to writes), targeting the
exact spot with the right temperature returns the SSD drive to brand new
state.  Not sure when this newest generation will hit the market though. [2]

Thanks Curt,

The WD green I bought a couple months ago didn't have the Load Cycle
Count Bug, so I'm temporarily assuming this one doesn't either. If it
does turn out to have that, I'll just replace it with a (hotter) black.

My current case is *much* cooler and more air-conductive and has much
more fannage than my old one, so one or two WD blacks can probably run
just fine without those lame hard disk coolers.

 Hi Bob,

Hi!

 First thank you for the detailed answer, you kind of preventively
 answered to all my doubts or interrogations. :)

Yay!  Then I was successful!  :-)  \o/

 I try to set up a new line of security (files and network) as I just
 changed country and instead of being in one mostly targeting others, I
 am now in one mostly targeted by others. :D

fun!

chmod -R u+rwX,go-rwx /home/user/Documents
 
 I ran this command to restart the process :
  find /home/user/Documents -type f -exec chmod u+rw,go-rwx -R {} \;
 and will make executable all following files according the needs.

More comments from me about the above.  It is pretty good.  It doesn't
do anything bad.  But it could be better.

  find $directory -type f

That will find all files below the specified directory.

  -exec chmod u+rw,go-rwx -R {} \;

That will chmod each file (each due to {} \;) to the specified
symbolic mode.  All good.

The -R is a little odd there.  That says to recursively change files
down a directory hierarchy.  Of course the find is only going to pass
it files so there won't ever be a directory seen.  The -R in that case
isn't doing any harm but neither is it doing anything at all.  Also
'find' is already the super powerful nice recursive command.  It is
the biggest and best tool in the toolbox.  Since recursive commands
can get away from people sometimes I think it best to use one of them
at a time.  :-)

The {} \; part is the traditional way to do -exec and you will find
it in many Unix text books forever.  It has some disadvantages though.
It invokes the command once for each file.  That isn't as efficient as
it could be.  More than a decade ago find was enhanced to include the
{} + construct as a new and better form of this.  For one + isn't
special to the shell and does not need to be escaped.  That is good by
itself.  But {} + also invokes the command once and passes the
entire argument list, or as much of the argument list as possible on
the system (it is system dependent), to the command.  Therefore it is
much more efficient since it reduces the number of fork and exec calls
and makes handling the large file lists more efficient.

If we polish up your command just a tiny bit we have this:

  find /home/user/Documents -type f -exec chmod u+rw,go-rwx {} +

Again, your original command is fine and got the job done.  I just
wanted to polish it up a small amount for next time.

  That is usually called UPG (User Private Group).
 ...
 
 After reading this, I actually found that :
 
 umask and level of security : The umask command be used for setting
 different security levels as follows:
 
 umask value   Security level  Effective permission (directory)
 022   Permissive  755
 026   Moderate751
 027   Moderate750
 077   Severe  700
 
 in there :
 http://www.cyberciti.biz/tips/understanding-linux-unix-umask-value-usage.html

I gave that a quick skim and that article seems factually accurate.
However trying to assign human fuzzy names Permissive, Moderate,
Severe to them is completely arbitrary and I disagree with the
direction at that point.  I would rather have features and
capabilities line up with the particular goals to be accomplished.

Because frankly I would say for Severe security that I would turn
the power off!  That would be severe! :-)  Otherwise it is just
different settings for different features.

 And I was planning to set a severe security plan. Based on the
 thinking that I have 3 computers (that only I use) to run behind a box
 and that I thought wiser to set them to the maximum security first, find
 out what they will exchange in second and then update the permissions
 accordingly, as I have very little impact on the box security.

Given all of the above I think that is a reasonable plan.  I can't
argue with the direction of your thinking.  But I also understand how
these permissions work and how they interact.  So I personally
wouldn't be recommending Severe.  I recommend a UPG umask 02 which
isn't even an option from the above list.  If you are a sole user on
your own system then it doesn't really matter.

 I then opted for the umask 077. I'm not sure if it's really justified
 but it couldn't do no harm.. I guess. :)

But for example if you share files by making tar files and sending
them out then that Severe setting creates problems for others when
they unpack the files and the settings are propagated to them.  I
wouldn't make a software release bundle that way for example.  Also
for example if you interacted with others through a version control
server then permissions can leak through there too.  Again it all
depends upon what you are doing and how you are interacting with
others.  I am not saying you are doing any of those things but I think
eventually you will want to share some files with someone and then you
need to be aware of the file permissions.  The old saying is right
that the devil is in the

I beg to differ. (I know, you already commented on your error while

Modern SSDs are no more fragile than a normal 2,5 spinning drive or
even less, since they have no problems with vibration or sudden G
shocks.

Have a look at

Of course, if you heavily abuse your SSD (like the techreport guys are
doing it), you will have a bad time.

But you can just use the drive like a normal hard drive, no need to
specially protect them like a raw egg, aside from leaving a bit of space
(10%) unused so the controller has more room for its wear leveling
algorithm.

My own data points for the Samsung 840 256GB Evo in my laptop look like this.

5505 hours running (~230 days) with ~3450GiB written. Wear_Leveling_Count

There is the Swap space, /var and /tmp on that SSD and I suspend-to-disk
the laptop every morning and evening.

I still expect this drive to outlive the laptop it is currently inside
by far.

You also can quite precisely pinpoint the moment a SSD will fail and
backup your data before while a spinning harddrive may fail without
warning at any moment.

I would advice Steve to put Swap and /var back onto the SSD as those are
the areas which gain the most from being on a fast storage medium. 

/tmp can be a tmpfs, which will be written to the Swap if needed, also
profiting from the fast SSD.

/run should already be a tmpfs in Debian Wheezy.

/home can then be on the WD because of the big space available there.

Sven.

Thanks Andrew,

I think the issue you're talking about is drive wear and tear, and like
you say, if your drive lasts 3 years, it's served its purpose and you
can buy double the space for the same price you paid for it three years
ago.

There's another SSD limitation: Deleted sections (I don't know the
official unit) don't necessarily become available for re-use by the OS,
unless you trim either with fstrim on a periodic basis, or by mounting
it with the discard attribute (but only if the drive supports trim,
otherwise, lost data). This is kinda sorta like issues with
fragmentation on the old MSDOS drive format.

If there comes a time when you want to return the whole drive to
section by section virginity, you can do that as follows:

https://wiki.archlinux.org/index.php/SSD_Memory_Cell_Clearing

However, this sounds like a dangerous operation for a lot of reasons,
so while this new Debian computer is my daily driver, I'll content
myself with occasional fstrim -v / commands.

Thanks,

btw It looks like exim4 first entered into Debian with Sarge (Debian
3.1, released 2005), here's a link with more info:

 There's another SSD limitation: Deleted sections (I don't know the
 official unit) don't necessarily become available for re-use by the
 OS, unless you trim either with fstrim on a periodic basis, or by
 mounting it with the discard attribute (but only if the drive
 supports trim, otherwise, lost data). This is kinda sorta like issues
 with fragmentation on the old MSDOS drive format.

Earlier Linux kernel had known problems with the discard mount option,
some earlier drives also had a very inferior implementation of TRIM,
resulting in very poor performance.

But all this has been fixed, both on the side of the Linux kernel (no
longer issueing TRIM for every deleted sector but queueing multiple
TRIMs into one big) and on the firmware side of the SSDs.

I see no problem in using discard with a recent kernel and a modern
SSD.

Sven.

   I can find plenty of tips to get started, but things are not doing
   the exact thing(s) the online guides are showing.

It is all about using Debian so this mailing list is good.  Lots of us
are using raid.

  Also, if you manually want to create a RAID 1 of two partitions use
  
  # mdadm --create /dev/md0 --level=1 --raid-devices=2 \
  /dev/sda1 /dev/sdb1
 
 Not attempting to install on a raid, but create a raid for storage

Linux-Fan's suggestion is a good one.  If you are not using it for the
system then it is easier to get experience building raid yourself as
in the above example.  François's suggestions were good too.

This is where I suggest that you think about using LVM in this
combination too.  If your disks are large, and today's disks can be
very large, then I suggest setting up LVM on them and allocating
smaller portions at a time to the file system.  It is much more
flexible than, say, having a 3T filesystem all in one place.

I would play with the above in order to get experience with raid.
Just setting things up, creating file systems, mounting them, checking
status.  Then unmount and wipe clean and then try a different
configuration.  Repeat a few times before you put it into service so
that you can understand what is happening.

To use LVM in the above start as suggested to create /dev/md0.  Then
set it up for lvm with something like this:

  Create a physical volume from the raid.  (It places a signature there.)
pvcreate /dev/md0

  Create a volume group using the physical volumes just created.
vgcreate vg0 /dev/md0

  The status of the above can be seen using the status commands.
  This will show summaries of space usage.
pvs
vgs

  Allocate 100G to a logical volume to be used for a file system.
lvcreate -L100G -nfirst vg0

  Make a file system on it.  (/dev/vg0/first is same as /dev/mapper/vg0-first)
mkfs -t ext4 /dev/vg0/first

  Mount it.
mkdir /srv/first
mount /dev/vg0/first /srv/first

I am just using first as an example.  Assuming there will be a
second.  Name them according to your needs.  I name mine after the
task.  I have root, home, var, audio, bak1, and so forth.

I always keep some disk space in reserve.  If a partition needs more
space then it can be expanded online on the fly.

  Extend a logical volume.
vgs
lvextend -L+25G /dev/vg0/first
resize2fs /dev/vg0/first

As long as you have free space available you can easily expand file
systems.  As we recently discussed in this list a few days ago
shrinking a file system is not as simple.  The simple advice is avoid
needing to shrink by planning ahead.  But expanding one is easy and
reliable.

I advice to play with different configurations while the disks are new
and unused to gain experience.  Easy to play now while there isn't
anything on the disks and you can try different things.  Then choose a
configuration that works for you and move forward with it in real use.

That is for today.  The records are routinely updated as mirrors come
and go.  Sometimes a mirror will have problems and need to be dropped
out.  That will be discussed on the debian-mirrors list.

Normally apt will round-robin among the servers in the list.
Sometimes one server will be having problems and will be slow.
Perhaps it is saturating its network connection.  Perhaps it is
suffering a denial of service attack.  Your experience sounds like
one of the mirrors at that time was likely suffering.

Alternatively there is http.debian.net.  It is a CDN.  It is a way to
use a redirector to dynamically select an appropriate mirror.  I have
been using it and it has been working well for me.  See this for
documentation.

  http://http.debian.net/

 Yesterday or Saturday, when I ran apt-get update, I got server access
 errors on wheezy, including backports and security. Ran apt-get clean
 and the access errors went away.

apt-get clean simply purges the downloaded .deb files.  It shouldn't
change what you saw.  But apt-get update will have an effect.  I
think one apt-get update failed due to the mirror selection but then
the next one succeeded.  Maybe.  I think it likely.

 Today, I get access errors again, and they go away after apt-get
 clean. And all packages are downloading at about a fifth my max speed
 from the provider.

It is also possible that the routes over the Internet through your ISP
are asymmetrical at this time.  You could traceroute to each of the
mirrors you are using in turn and see how the routes are different.
Look at the times.  Use ping to check each.  It isn't unusual to find
routers in a path that are sick and troubling.

There is a Debian package netselect that can be used to probe
different archive servers.

  apt-cache show netselect

  http://github.com/apenwarr/netselect

 I'm feeling a little paranoid about this. Should I just assume my
 wan-side connection is getting saturated for some reason?

I wouldn't be worried about security because Debian releases are
cryptographically signed.  But I would probe and try to understand the
network slowness.

My question is this: Would a ten year old disk be worth the SATA port
it consumes? Would it be worth its power demands and heating? Ten years
ago, 500GB was a Big Friggin Deal (tm). Today, any fool can go to any
store and get a 4TB drive for less than $200. If you do stuff that
requires disk space, keeping an old drive alive becomes moot after a
certain amount of time. I have all sorts of 100GB drives from ten
years ago: I just take them out to the driveway and do my 20oz hammer
based data wipe.

Here's a related true story. Reading the newspaper in 1994, I saw
Egghead Software was selling a 1000MB drive for $799.00. I figured such
a great price for such amazing technology must be a misprint, but
called them anyway. Yes, they were selling 1000MB for $799.00. I made
them promise to hold one for an hour, RAN to my car, broke every speed
law getting to Egghead, walked in, outwardly casually and inwardly
figuring this can't be true, asked for the drive, handed them my credit
card, and got charged $799.00. Still figuring there'd been a mistake
and I'd be arrested for shoplifting on the way out, I ambled out, got
in my car, carefully drove 2 blocks away, stopped the car, and did a
victory dance.

3 years later I bought an IBM Deskstar drive with 6 times the capacity
for $300.00 :-)

I expected it to look like Ubuntu but without the layer of we do it

I didn't expect a lot of the little differences in networking, in
Dovecot, etc. That being said, they're much more similar to each other

These aren't even SATA but IDE; but they're on old machines
that give satisfaction for what they're used: storing CAD 
drawings updated very often and are backed up when needed.
So I don't really need extra space (except if I become very
lazy and let the HDz get bloated:)

In production world, you avoid touching what's working right
until it really breaks (remember that PCI bus superseded the
ISA bus only a fistful of years ago).

I understand your way (especially the HD's one AT THE TIME YOU

For large calculations, I use big juicy multi-core/CPU machines
with several TB of RAM, but for my every day reporting or stuffs

I think you are missing the problem associated with SSd. The wear 
problem is associated with the amount of free space. If the drive is 
99.99% full, you could probably wear the drive out in no time at all. 
The wear problem is prevented by using free space that has not been 
written to it. thus if 00 % full drive will wear out faster than a drive 
that is 1% full. If you do not speak in context of the percentage full 
the benchmarks are not too useful.


Most consumer grade ssd are limited to about 10K writes per cell. If you 
exceed the limit, dead cell. Remember that another factor involve is the 
number of spare cells. all of these things play in the role when an ssd 
fails.
