Re: Erreur d'un partitionnement assisté avec LVM chiffré

2014-02-25 Thread Sébastien NOBILI
Le lundi 24 février 2014 à 17:21, LaNaar Dakoté a écrit :
  Apparemment, LVM peut garder les volumes physique en cache pour éviter de

La partition /dev/sda1 doit contenir un en-tete LVM… La commande suivante
permettra de copier cet en-tête dans un fichier :
dd if=/dev/sda1 bs=512 count=255 skip=1 of=/tmp/sda1.txt

Ensuite, en recherchant du texte dedans, tu devrais trouver ce qui induit LVM en
erreur :
strings /tmp/sda1.txt

Il va falloir effacer cet en-tête. Il est plus que recommandé de faire une
sauvegarde de la partition avant !
umount /boot
dd if=/dev/sda1 of=/var/tmp/sda1.img

Ensuite, cette commande devrait faire l'affaire :
pvremove /dev/sda1

Re: USB Installation

Bonjour,

Le mardi 25 février 2014 à 13:49, Diogene Laerce a écrit :
 J'ai installé Wheezy sur une clef USB. Tout fonctionne mais j'aimerais avoir
 des conseils sur la gestion des cartes graphiques. En effet, selon
 l'ordinateur
 sur lequel je vais booter ma clef, le système graphique sera différent.
 
 Quelle serait donc la meilleure méthode pour gérer cela ?

J'ai à peu près la même configuration. Je laisse Xorg gérer ça comme un grand et
ça se passe plutôt bien. Il faut juste t'assurer que tous les drivers graphiques
sont correctement installés, meta-paquet « xserver-xorg-video-all ».

Avant, en fonction de la configuration réseau, j'identifiais la machine et je
déposais un xorg.conf adapté… Je m'en passe très bien depuis plusieurs années.

Bonjour à tous!

Pour clarifier ma pensée, ce n'est pas contre la distribution que j'en 
ai (mes excuses aux développeurs si on l'a cru)  mais plutôt contre 
l'allusion aux  retraités que je trouve tendancieuse et préjudiciable.


Voilà.

Bonjour Roger,

Content de voir un retraité Canadien sur la liste, ça fait plaisir.
Je ne suis pas retraité mais plus très jeune non plus...
Dans cette liste il n'y a pas d'âge, L'intérêt à Debian n'en a pas non plus.
Les gens sont sympa. Juste de temps en temps des hors sujets comme nous 
maintenant.

On apprend beaucoup de choses juste en lisant les autres.
Et quand on peut aider, c'est génial.

A bientôt.

Pb de noyau rt en testing

2014-02-25 Thread Vincent Besse
Bonjour,

j' ai un portable en testing. Comme je m' en sers essentiellement pour
travailler du son, je tourne (tournais...) avec le noyau rt. Depuis ma
dernière mise à jour, la machine ne démarre plus. Je suis passé du
3.12.6-2 au 3.12.9-1. En démarrage normal le dernier affichage est
'Booting the kernel...' et en mode recovery les 3 dernières lignes qui
s' affichent sont:

[0.216477] hpet0: at MMIO 0xfed0, IRQs 2, 8, 0
[0.216481] hpet0: 3 comparators, 32-bit 14.318180 MHz counter
[0.218517] Switched to clocksource hpet

...puis plus rien. J' ai pas une connaissance très approfondie du
noyau, mais ça me semble pas incohérent si c' est un bug du noyau temps
réel que ça s' arrête là.

Je démarre sans soucis avec un noyau 3.12.9-1 'normal'. Avant de
déclarer un bug, j' aurais bien re-essayé un 3.12.6 rt (ou plus
ancien) mais il n' est plus dans les dépots. Y a-t-il un moyen de
retrouver une ancienne version?

Et précision supplémentaire c' est en amd64.

Merci,
Vincent

Bonjour,

Je pense que tu peux récupérer le tarball qui t'intéresse ici:
https://www.kernel.org/pub/linux/kernel/v3.x/
puis le compiler toi-même après dézip:
- cd linux-x.y.z
- récupérer un /boot/config-xxx en .config
- make menuconfig puis save puis exit
- make -j nombre KDEB_PKGVERSION=1.nomcustom deb-pkg (-j nombre si +ieurs CPU)
- dpkg -i chemin/linux-x.y.z*.deb

dh_auto_configure et le CPU

2014-02-25 Thread LOMBARD Maxime
Salut à tous les Debianistes,

Je suis en train de me créer moi-même mes paquets Wine en utilisant un mix
du dossier debian des paquets d'Ubuntu et Debian.

Tout fonctionne très bien, la compilation complète de Wine fonctionne et la
création des différents paquets également.

Mais voilà, pour compile wine, j'utilise dans le fichier debian/rules la
commande 'dh_auto_configure'. La commande en elle-même fonctionne mais le
petit soucis, c'est qu'il n'y a qu'un Core sur les 4 que je possède (j'ai
un I5) qui est utilisé. Donc la compilation est un peu longue.

Si je remplace cette commande par

 ./configure
 make -j4


J'ai un message d'erreur au lancement de debuild me disant qu'il manque un
séparateur à debian rules:9 (donc à la ligne 9 du fichier debian/rules qui
correspond à la ligne du make -j4 juste avant le else)

1- Impossible de corriger cette erreur vu que je ne vois pas ou il en a
une. De plus, le duo ./configure + make -j4 fonctionne très bien sur
32-bits. Je n'ai cette erreur que lors de la compilation sur 64-bits

2- Y a-t'il la possibilité de dire à la commande dh_auto_configure
d'utiliser les 4 cores et non un seul ?

Merci

PS : j'attache le fichier rules avec les différentes modifications.

 Cordialement,  Valentin

Lors du dernier salon 2013 Solutions Linux et OpenSource,
une équipe d'un Unix Free reconnaissait d'elle même des bugs 
dans les dernières versions et préconisait d'attendre.

Je pense qu'il s'agissait de FreeBSD
(sinon OpenBSD ou NetBSD ?)

S'agit-il de la suite de la déception des aficionados de FreeBSD... ?

Re: USB Installation

Merci pour ta réponse.


J'ai installé Wheezy sur une clef USB. Tout fonctionne mais j'aimerais avoir
des conseils sur la gestion des cartes graphiques. En effet, selon
l'ordinateur
sur lequel je vais booter ma clef, le système graphique sera différent.

Quelle serait donc la meilleure méthode pour gérer cela ?

J'ai à peu près la même configuration. Je laisse Xorg gérer ça comme un grand et
ça se passe plutôt bien. Il faut juste t'assurer que tous les drivers graphiques
sont correctement installés, meta-paquet « xserver-xorg-video-all ».


Donc un Xorg --configure avant de démarrer X et ca roule ?

algo, Virtual BOX esta integrado en Debian y dice dar mejores

En este caso se trata de una maquina (para uso personal) pero que voy a

pero se van a usar mas en remoto que en local y necesito alto
rendimiento multimedia en remoto, incluso juegos.
No se trata de un gran sistema para una empresa con muchos servidores

 Hola buenas, tengo una pregunta que alomejor es un poco tonta pero
 siempre la he tenido y ahí va...
 
 No entiendo cuál es la finalidad de usar iptables. 

Jo-do. Con perdón.

 Es decir, se usa para filtrar y abrir sólo lo que tú quieras o cerrar,
 pero si tengo sólo instalado un servidor web y un servicio ssh, qué más
 da si uso iptables para aceptar sólo conexiones a esos puertos 80/22
 respectivamente y cierro todo lo demás, si aunque no ponga iptables
 también van a estar abierto y escuchando...

Un cortafuegos avanzado como iptables también permite controlar el número 
de peticiones permitidas desde/hacia ciertos puertos para evitar dejar 
saturado el servicio o servidor.

 ¿Para que no puedan explotar otros puertos abiertos de otros servicios?
 No sé alomejor estoy equivocado pero no le veo mucho sentido excepto
 cerrar todo y abrir solo lo que quieras... No sé si me explicado bien.

Es una medida adicional de seguridad.
 
 Es decir, imaginaros que sólo tengo el servicio web activo, puerto 80,
 todo lo demás que tenga algún puerto corriendo los paro, qué diferencia
 habría de usar ahí iptables a no usarlo...

Si tienes la certeza de que no hay ningún servicio accesible desde el 
exterior que esté en ejecución con un puerto abierto, no hay ninguna 
diferencia.

Vale, si usas MySQL como almacén de datos para las cuentas de los

1/ Crear la base de datos
2/ Crear la tabla mysql con la información de los usuarios y los alias
3/ Ir añadiendo los datos a la(s) tabla(s) de usuarios/alias

En definitiva, si usas MySQL creo que necesitarías un gestor de bases de

La gestión sin control no sirve de nada. Si interpones la facilidad de 
uso (o de gestión) al rendimiento o capacidad de un sistema de correo u 
otro, tarde o temprano tendrás problemas. 

Lo que quiero decir es que tu servidor de correo puede funcionar sin 
herramientas de gestión (puedes añadir usuarios manualmente a la bdd) 
pero no puede funcionar si tienes caído alguno de los servicios y no 
sabes cómo solucionarlo porque no entiendes el funcionamiento de la 
aplicación.

¿Como evitar usuarios spam registrados por robots?

¿Lo qué?
Tengo una web que estaba padeciendo una ola de registros -fraudulentos- 
por robots, es decir de modo automatizado (sobre 100 diarios).
Esto a pesar que tengo deshabilitado el autoregistro y la 1ª password se 
enviaba via email. El robot conseguía tras sus intentos baldios añadir 
usuarios y después insertar spam en los perfiles.

Desde la última oleada, he desactivado el registro y aun no tengo
solución.
Espero que tengan algun remedio, receta o consejo para mi. Por supuesto
las soluciones más simples y sencillas son las más apreciadas.

Si explicas un poco más lo que te preocupa y lo que has hecho, mejor :-)
Lo que he hecho a sido lo mas bruto y radical del mundo, no es posible 
registrar usuarios nuevos, mas que por el administrador; y esto claro no 
es una solución.
A raiz de los comentarios y la discusión del hilo original deduje que se 
podría manejar a estos bichos (robots) y acaso mantenerlos inoperantes.
Esa es la cuestión. ¿Que les parece? Cualquier dato adicional de mi 
problema que sea conveniente añadir me lo dicen. Mi cms es plone, pero 
creo que es un problema que afecta a todos.

Vamos a ver. Varias cosas:

a) No hagas top-posting (esto te lo dirán otros a parte de mí)
b) No secuestres un hilo (esto te lo dirán otros a parte de mí)
c) ¿Tu tienes claro lo que es un firewall?

 Para hacerlo en sentido llano: un firewall perimetral (porque el 
interno es otro tema) es como si fuese la puerta de tu casa que da a la 
calles. Tú lo que quieres controlar lo tienes que hacer instalando una 
alarma, es decir: tienes que instalar productos/componentes específicos 
para lo que quieres hacer.


O sea que sí: ya te puedes ir explicando de la forma más concienzuda que 
sepas.

Poner a funcionar el Scanner de una Canon imageRunner 1023

2014-02-25 Thread academia
Hola lista. Un amigo necesita le ponga a funcionar su impresora Canon
imageRunner 1023 en su Debian 6. La impresora como tal tiene algunos
problemas mecánicos para la impresión, de rodillos defectuosos. Él lo que
quiere es que le funcione el scanner. Desde CUPS 1.4.4 conozco que existen
los drivers de esa impresora.

Mi duda está en que si al instalar los drivers de la Canon imageRunner
1023, ¿es suficiente para que funcione el scanner o hay que instalar algún
otro paquete adicional?. Quisiera me expliquen detalladamente qué tengo
que hacer. NO TENGO INTERNET.

Deberás instalar el programa saned, entre otras. Además, deberás poner, si
te lo detecta con sane-find-scanner, si te aparece del mismo, una regla en
jdev, para luego hacerle saber al scanner, tener como usuario para
permitirlo, porque de hecho, va a funcionar directamente como root, no como
usuario.

Por ello (un ejemplo):

found USB scanner (vendor=0x04a9 [Canon,Inc.], product=0x269d
[iR1018/1022/1023]) at libusb:002:002

Deberás poner como sigue:

BUS==usb, SYSFS{product}==269d, MODE=664, GROUP=scanner

Puedes comprobar en /proc/usb/devices para escáners USB.

Si necesitas alguna cosa, me lo dices, y te digo el cómo. No es difícil. Yo
tengo un scanner y, a mí, me detecta de otra manera, pero le tengo puesto
una regla buena y me detecta bien. ;)

[OT] Proxy HTTPS transparente

2014-02-25 Thread Vicios

Buenas noches,

Llevo algún tiempo peleándome con Squid para que trabaje de forma 
transparente con el tráfico HTTP y HTTPS. He compilado, con soporte SSL, 
tanto el paquete squid3 de Debian como la última versión de Squid con el 
mismo resultado.


Estoy utilizando un certificado auto-firmado generado con OpenSSL y 
aunque recibo la advertencia de seguridad en el navegador, puedo acceder 
al contenido.


El problema viene al utilizar el navegador Chrome y acceder a ciertas 
páginas como google o paypal (imagino que habrá muchas más) que muestran 
la siguiente información técnica:


www.google.es le ha pedido a Chrome que bloquee los certificados que 
contengan errores, pero el certificado que ha recibido Chrome durante 
este intento de conexión contiene un error.

Tipo de error: HSTS failure
Destinatario: www.miweb.es
Emisor: www.miweb.es
Hashes de clave pública: sha1//56eU2r1eF2ylEej7cDkTo0SbBk= 
sha256/uoXtr1FR/avDhIbWRaqKcgpVL6kV4Yvqb+EveDoSqzc=


Desde Firefox no tengo problemas tras confirmar la advertencia de 
seguridad con ninguna página HTTPS pero a la hora de utilizar Chrome hay 
ciertas páginas que no quiere.


En Squid, para el tráfico HTTPS estoy utilizando https_port y ssl-bump 
junto con alguna acl para manejar errores y de momento es lo mejor que 
he encontrado salvo el problema con Chrome.


Si no es indiscreción... ¿Cómo gestionan/manejan/filtran las conexiones 
HTTPS?


Gracias y un saludo.
Fernando.

Du måste ha ADSL-modemet kopplat före alla andra telefoner. Det
innebär att splittern (filterburken) måste sitta i det första jacket

kryptering av diskar

2014-02-25 Thread jan
Hej Alla!

Nu är jag frågvis igen...

Om man läser på om TrueCrypt (http://www.truecrypt.org/) verkar allt
rosenskimrande. Förmodligen är det ett utmärkt alternativ om man vill
kryptera hela diskar eller delar därav.

Men, nu verkar vi linuxianer av någon anledning föredra dm-crypt
antingen i skepnaden av LUKS, cryptsetup eller cryptmount.

Själv har jag använt GPG och encfs till stor belåtenhet men inser att
där finns vissa svagheter, som tex att det är trivialt att konstatera
att jag har krypterade filer på mina hårddiskar.

Nu är det dags att fixa till en av mina servrar (och några USB-diskar)
till något som helst inte skvallrar om vad det är jag har krypterat och
helst ser ut som om det är en rensad disk.

Vad föreslår prenumeranterna? Vad har fungerat bra för er? Enkelt?
Krångligt? Best practice?

encfs tillsammans med crypkeeper eller Gnome Encfs Manager (som fungerar 
bättre med Unity, som jag idag föredrar) är IMHO trevliga och bekväma 
alternativ för att kryptera en katalog. Speciellt bra är tekniken när 
man synkroniserar katalogen, t ex via någon publik molntjänst eller med 
rsync då varje fil är representerad separat (dock med krypterat namn och 
innehåll). Synkningen behöver bara agera på ändrade filer.


Vill du inte bara kryptera dina filer utan även gömma dem eller låta dem 
se ut som något annat så är det steganografimetoder du är ute efter. t 
ex steghide eller bara en cat 
http://www.unixmen.com/steganography-in-ubuntu-hide-your-files-inside-an-image/


Googla på encfs och steganography så får du förslag på hur du kan gömma 
ett krypterat filsystem.


Har du stora mängder data som skall gömmas blir det svårare eftersom 
dina data måste se ut och någorlunda fungera som en annan stor mängd 
data. Du kan iofs alltid göra en swap-partition (som du låter bli att 
använda). Göra steghide på en binär i /var/lib/mysql-katalogen, döpa en 
terabytestor partition till skräp eller liknande. Men den som letar 
kommer alltid kunna hitta dina gömda filer och då hänger det på 
krypteringen igen.



GPG är ett utmärkt verktyg när du vill kryptera något med asynkrona 
nycklar, dvs kryptera en fil som bara en viss mottagare kan packa upp 
utan att behöva utbyta någon hemlighet. Sätter du ett lösenord på 
pdf-fil, delar en encfs-katalog med någon, så måste du även meddela 
lösenordet på något vis till mottagaren (synkrona kryptosystem).

[i3]Colors and transparency problems with rxvt-unicode-color

2014-02-25 Thread Anubhav Yadav
Hi,

If I start a new urxvt terminal using the command,

 urxvt -name Terminal -fn xft:Monospace:pixelsize=11 -fade 20 +sb
-depth 32 -fg white -bg rgba:2000/2000/2000/

urxvt starts just the way I like it.
But if I put this in ~/.Xresources, it would never work:

and I have commented it out to prevent clashing it with
Urxvt*background option which is given in rgba format. I would love if
someone can convert the hex value into a working rgba format as
required for this configuration file?

2) I also feel that only 2-3 colors are shown in the shell. But when I
use weechat-curses all colors are shown. But linux command like ls and
grep won't give me any colors.

'tput setaf' wont output anything.

Here is something I found in my .bashrc
# set a fancy prompt (non-color, unless we know we want color)
case $TERM in
xterm-color) color_prompt=yes;;
esac


Now I have installed both xfce terminal and xterm.

Any inputs would be greatly appreciated!

Thanks guys for your suggestions.

I have tried kernel 3.12 and then the recently released 3.13 in sid without
any luck.

The thing is that, from time to time, suspend works (maybe 1 out of 15

fancontrol wheezy Dell T7610

2014-02-25 Thread Dan
Hi,

I recently bought a workstation to do calculations. It has two Xeon
processors with 16 cores and 32 threads in total. I realized that the
temperature gets very high on high load typically 80C. That is way too
much. Then I changed the fan speed in the bios from auto to high. Now
temperatures are reasonable 45C, but it is very noise and it never
stops (even with no load) I have to reboot the computer to change the
fan speed..

I would like to use fancontrol but I  get:
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

It seems that lm-sensors do not read properly the fan. I get:

I edited /etc/default/grub and added
GRUB_CMDLINE_LINUX_DEFAULT=quiet acpi_enforce_resources=lax
as suggested in http://hydra.geht.net/tino/howto/linux/fixes/w83627hf/

But no success. I checked /proc/cmdline and the option
acpi_enforce_resources=lax has been taken by the kernel.

Any idea or suggestion?

Thanks a lot,

Re: Am I paranoid?

2014-02-25 Thread ha



By the way, do not have sshd installed (and there is no /usr/sbin/sshd).


I mentioned sshd as an example. There are plenty of ways to do remote
connection to the host (telnet, VNC, XDMCP), all of them can be used
for the root access.

Just to be on a safe side, scan your host with 'nmap -sT -sU 1-65535'
for both ipv4 and ipv6. Consider blocking everything unneeded with
iptables.




Great! This thread starts to look like a small tutorial on useful commands!

Please note the difference between *are/is* installed, and *were* installed.

I would expect dpkg -S to fail if those packages had been wrongly
removed (corrupting dpkg database) but the pam and man files are
extremely unlikely to be the result of malware. The OP never responded
to my query about the other files that would have been installed - or
checked the installation history with dpkg --get-selections (it won't
show if purge was run, but then, those files would likely not be left).



Sorry I didn't follow up on this one...
What info did you requested?
How can I check if the package was installed (but is there no more)?
I believe that dpkg --get-selections shows only available packages.

If the package was *purged* I don't think it should be different that
never-installed-in-the-first-place. (If I'm wrong, somebody shout!)

However, if it was installed and then removed, then the configuration
files should remain, and dpkg --status $packagename would report:

 Status: deinstall ok config-files

For the uninitiated: Removing a debian package will not remove the
configuration files. Which is a brilliant if you subsequently
re-install the package. To also remove configuration files, you need
to *purge* the package.  Since configuration files are usually very
small, most people are not too bothered about the difference.

However Neither seems to match the situation of the original
poster - (s?)he seems to have both a binary *and* a configuration
file...

Re: Am I paranoid?

My guess is that this situation is the result of invoking:
dpkg -X *deb /

or, simply unpacking a tarball into /.
But your guess is as good as mine.



The only package I installed via dpkg was youtube-dl, as I couldn't get 
it by invoking apt-get install (and I still can't).
I downloaded it from the browser, and true, I did not verified the 
package (is there a common way to do that?)




Yet, there is another thing - OP claims that he didn't install anything
like this.

Reco




I prefer Virtualbox and QEMU over VMware, and on this machine I had no 
need to install virtual machine at all - yet.


However, I used pip to install virtualenv as suggested by one python 
package. Perhaps virtualenv uses some VM package?

I'd hate to hold anyone responsible for their memory - AFAIK no one can
remember what they don't remember (this is why we take notes and run
script) - I can only assume their memory is complete. With other areas a
guess/instinct may be good enough - with security I prefer proof.
Even if they didn't specifically install open-vm-tools it could well
have been a dependency



Great point. It made me laugh. :-) Hopefully I will embrace part of that

Looking at those files makes me think of a possible installation error:
that one or more partitions on the old install were used and mounted
without reformatting for the new install.

Is there a timestamp check that could be performed (install time/date
for the file, rather than the datetime that ls -l shows?





Could be. After I removed Windows I had several attempts to boot into 
Debian as the GPT gave me some headache. It is possible that I made a 
mistake and did not format the partition every time.


How could I do this timestap check you mentioned?

Re: 3.13 Kernel

2014-02-25 Thread Florent Peterschmitt
When the 3.13.0 was out, some problems with filesystems seems to get in[0].

But in general I don't see any improvement, I run VMs and heavy things
and it still seems as long as usual :)

So it might be a very subjective impression ;) If you want, you should
make some benchmarks to get more formal results.

Run a database, 3D rendering, filesystemcpu stress and so on…

Just a thought, do you need to say ls --color=auto? The dircolors
should, I believe, already be set up nicely.

 
 'tput setaf' wont output anything.
 
 Here is something I found in my .bashrc
 # set a fancy prompt (non-color, unless we know we want color)
 case $TERM in
 xterm-color) color_prompt=yes;;
 esac

Note that RXVT isn't XTerm. You'll probably find that your $TERM is
'rxvt-unicode-256color'.

 
 
 Now I have installed both xfce terminal and xterm.
 
 Any inputs would be greatly appreciated!

 According to the manpage it is not necessary to restart the daemon, so 
 this should not fix your problem. How about you attach your crontab and 
 the relevant parts from syslog? Also check if you have anacron 
 installed.
 

First, as Andrei surmised, restarting cron has made no difference.
It's still starting late.

My /etc/crontab is as follows:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 ** * *   rootcd /  run-parts --report /etc/cron.hourly

--report /etc/cron.weekly )
52 11 * *   roottest -x /usr/sbin/anacron || ( cd /  run-parts
--report /etc/cron.monthly )


I DO have anacron installed.
I do not know what is relevant from syslog.
I find no mention of cron, crontab, or logrotate in /var/log/syslog
at all.

 If you do not want this process to take precedence, why did you choose
 such a low niceness to other processes? Shouldn't you have chosen
 something above 10 or at least above 0?

Perhaps I misunderstand, but from reading man nice,
my understanding is that -20 is the hightest priority,
and 19 is the lowest, so I assume 15 was low priority.
I've tried to renice the process in htop now that it's running again,
and that doesn't seem to be working.

Also note that nicing a process won't, by itself, make the process use
less that 100% CPU. It'll just make other processes more favoured. If
the rest of the system is idle, then a nice process can easily use 100%.

hostname does not match certificate

2014-02-25 Thread Tony Baldwin
Using mutt this morning, I was informed that my postfix certificate had expired 
a few days ago.
I made a new one with:

openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout 
smtpd.key -keyform PEM -days 365 -x509

I'm fairly certain this is precisely how I did it a year ago.

the hostname on the box is tonybaldwin.info
the fqdn is tonybaldwin.info

but every time I send a message, I'm told the hostname on the server doesn't 
match
the hostname on the certificate.
I'm a bit lost on that.
I can accept it (I've been choosing accept (o)nce until I can resolve this, 
but
(a)ccept always is an option)
It doesn't seem to be impeding me from sending or receiving mail,
but I have to wonder if it will hinder others in receiving my mail (if their 
provider
sees a problem with my cert?).

This shouldn't happen on a regular basis, though, should it?
Unless something is routinely writing huge and/or corrupt logs,
but if they're rotated daily, I can't imagine them getting huges,
so we'd have to assume that maybe something is writing corrupt logs?
How would I diagnose that?

Not, it seems to be starting around that time.
Runs for about 30 to 60 minutes on any given day.

Re: [i3]Colors and transparency problems with rxvt-unicode-color

2014-02-25 Thread Anubhav Yadav
 I use URxvt*background: [95]#00, which applies a 95% transparency
 to black. That might be useful to you.

Yes that did it. Thanks a lot. I was also having 'r' small instead of capital.

 Note that RXVT isn't XTerm. You'll probably find that your $TERM is
 'rxvt-unicode-256color'.

Yes and I changed that in the .bashrc too. But didn't help much.

However uncommenting the line
force_color_prompt=yes

did make my prompt (user@hostname:$) coloured.

But that was the same color as my background. Made it
look even more uglier.

Scott Ferguson scott.ferguson.debian.u...@gmail.com wrote:

  My guess is that this situation is the result of invoking:
  dpkg -X *deb /
  
  or, simply unpacking a tarball into /.
  But your guess is as good as mine.
 
 Maybe, certainly my guesses as to the cause are similar... the tarball'd
 be tricky (debsums).

No, of course not. debsums only checks files which belong to an
installed package. Such 'orphan' files are invisible to debsums,
regardless of the way they landed into filesystem.


  What I cannot understand is how exactly removing a package would fix
  this issue if both apt and dpkg claim that the package is not installed.
 
 *If* the package was legitimately installed - then it's removal would
 ease Ha's concern. Though without understanding how it happened it's no
 less likely to happen again.
 
 I haven't seen the result of checking the selections with dpkg. There
 are a couple of scenarios where the user/operator can damage the dpkg
 database - I'm not familiar with all of them.

Possible scenario, yes. Still, installing and deinstalling a package -
I see how it could work. Simply deinstalling non-installed package seems
like 'magic'.


  It is possible[*1] vmtoolsd is a trojan - though that scenario means the
  rest of it's expected files would likely be there (and dpkg -S would
  find it) - an md5sum is a simple way to check.
  
  If you browse this part of thread up, you'll see that OP did checked
  the root filesystem with debsums, and debsums haven't found anything.
  Therefore I agree that it's unlikely that vmtoolsd is a malware.
  
  
  Simply re-installing a system because some one suspects a security
  breach - will zero evidence to support the suspicion, is not a good
  idea.
  
  Agreed. That's why I wrote earlier that no reinstall is necessary.
 
 Unfortunately the OP's editing combined with my free time limitations
 mean I'm not sure who said what - so that comment wasn't aimed at any
 particular participant in the thread. It's a convoluted thread and at
 present there's still three recent posts I haven't read.

Ok, no harm done to anyone, if you ask me. I wrote this part to merely
clarify things.

  By all mean re-install from a known clean source - but first check
  to see if the installation was legitimate (check package selections
  status), check suspect file/s. Otherwise it confirms nothing and do
  even less to help detect and defend against real malware.
 
  Always test when security is in doubt - but it's probably not a good
  idea to rule out user error.
  
  Yet, there is another thing - OP claims that he didn't install anything
  like this.
 
 I'd hate to hold anyone responsible for their memory - AFAIK no one can
 remember what they don't remember (this is why we take notes and run
 script) - I can only assume their memory is complete. With other areas a
 guess/instinct may be good enough - with security I prefer proof.
 Even if they didn't specifically install open-vm-tools it could well
 have been a dependency

True. But, reading other parts of the thread, now I blame multiple
reinstalls of Debian over the same partition.

Dear Ingmar,

Thanks for your answer

I  didn't open the computer. I do not know if the fan connectors have 4
pin. I prefer not to open the computer. It is on warranty.

I run sensors-detect, but no success. It only finds coretemp.

The option that I added in grub was just to try something.

I found out that I can control the fan with i8kutils. I can turn it on and
off, but I can not use it with fancontrol. I would prefer to be able to use
the fan with the standard fancontrol but at least it works. The drawback
is that I can not control the speed.

Thanks,
Dan

Sounds like what you really want is for your local nameserver to forward the

forwarders option for named.conf.

No, not sendmail. The server has postfix and dovecot,
I'm using imap, not pop, and sending the mail through the dovecot smtp

smtp://t...@tonybaldwin.info:passwordh...@mail.tonybaldwin.info:25

Of course, the hostname on the box is not mail.tonybaldwin.info

 I recently bought a workstation to do calculations. It has two Xeon

 Any idea or suggestion?

Is it the CPU fans or the chassis fans generating the intolerable noise?
 If just the CPU fans, you can simply replace them with quieter models.
 If your system accepts wide coolers, two of this model would be suitable

http://www.newegg.com/Product/Product.aspx?Item=N82E16835114120

If it accepts only narrow coolers, then two of these

http://www.newegg.com/Product/Product.aspx?Item=N82E16835114142

The 8 core Sandy/Ivy bridge Xeons range from 95-150 watts Thermal Design
Power, or 180-300 watts combined for a 2 socket system.  The stock style
fans required to evacuate this amount of heat, plus that of the GPU,
HDDs, system chipsets, DRAM, VRMs, etc are not going to be quiet.  Dual
socket/professional workstations are generally not very quiet machines.

Beyond replacing the CPU coolers there are a number of ways to reduce
the noise while still achieving the required airflow for proper cooling.
 Run the fans at full RPM all the time, while damping the interior of
the chassis using acoustic damping pads such as

http://www.acoustiproducts.com/en/acoustipack.asp

When applied correctly, thoroughly, to all interior surfaces, this will
absorb much of the high frequency fan noise emitted by the CPU and
chassis fans.  I don't use such self stick thin foam pads as they are
over priced and the performance isn't that great for the money.  I use
1.5 acoustic egg crate foam attached with 3M Super 77, as the egg crate
foam yields superior acoustical damping performance.

http://www.parts-express.com/acoustic-sound-damping-foam-1-1-2-x-24-x-18-ul-94--260-516

This is the material used inside of speaker cabinets and recording
studios.  The self stick thin foam is much easier for most people to
install which is why I mentioned it first.

You can also use a manual fan speed controller such as

http://www.newegg.com/Product/Product.aspx?Item=N82E16811999171

This allows you to fine tune noise level vs cooling performance using
continuously variable knobs.  This requires replacing any existing PWM
fans in system with non-PWM fans if using a standard fan controller.
There are some PWM controllers on the market but I'd avoid them.

Pat's correct. That's the proper way to do what you want.  If you like, you can 
have two forwarding server (for redundancy in case of failure of the primary 
server).

A good way to do that is with the dnsmasq package.  It provides both DNS 
(forwarding if you configure it) and DHCP.  Configuration is remarkably easy -- 
it uses /etc/hosts and /etc/ethers as input.

The ISC dhcp server is much more flexible, but (as a consequence) takes a lot 
of configuring.

Dnsmasq is *way* easier.

Build a 3 sided box out of 3/4 MDF with outside dimensions, matched to
the T7510

11W x 18H x 28D

Cover the inside and outside with low pile carpet, using 3M Super77
adhesive or simply lots of T50 1/4 staples.  Wrap it around the edges
and neatly trim it so it looks half way decent.

Lower it over the T7610 so you have 3.5 overhang front and rear.  This
will pretty much kill the noise problem instantly.  Carpeting the
outside isn't necessary for killing noise, but looks better than bare
MDF.  You could use black synth wood grain Melamine or even Maple veneer
if want it to really look fancy.  Finish is your choice.  You could
substitute 1.5 thick egg crate acoustic damping foam on the inside.
Carpet remnants are usually easier for most people to acquire from a
store or relative/friend, probably cheaper as well, and just as
effective at killing the noise.  I've build a few of these in the past
and they just work.

But seriously, you are correct.  Encasing the tower in a sound dampening

I had a similar problem, and I will get to it in a second.
But first: bridged Wifi might not work. Some AP refuse to accept packages,
which are not from the interface bound to it. So you would have to
masquerade those packages with ebtables.

Here how I did it.
I created a dummy-bridge which is completely internal

in /etc/network/interfaces

...
iface dummy0 inet manual

auto br0
iface br0 inet static
address 10.0.77.1
network 10.0.77.0
netmask 255.255.255.0
broadcast 10.0.77.255
bridge_ports dummy0
bridge_stp yes
post-up /bin/echo 1  /proc/sys/net/ipv4/ip_forward
post-up /sbin/iptables --table filter --insert INPUT --source \
10.0.77.0/255.255.255.0 -j ACCEPT
post-up /sbin/iptables --table filter --insert FORWARD --source \
10.0.77.0/255.255.255.0 -j ACCEPT
post-up /sbin/iptables --table filter --insert FORWARD \
--destination 10.0.77.0/255.255.255.0 --match state --state \
ESTABLISHED,RELATED -j ACCEPT
post-up /sbin/iptables --table nat --insert POSTROUTING --source \
10.0.77.0/255.255.255.0 ! --destination 10.0.77.0/255.255.255.0 -j \
MASQUERADE
pre-down /sbin/iptables --table filter --delete INPUT --source \
10.0.77.0/255.255.255.0 -j ACCEPT
pre-down /sbin/iptables --table filter --delete FORWARD --source \
10.0.77.0/255.255.255.0 -j ACCEPT
pre-down /sbin/iptables --table filter --delete FORWARD \
--destination 10.0.77.0/255.255.255.0 --match state --state
ESTABLISHED,RELATED -j ACCEPT
pre-down /sbin/iptables --table nat --delete POSTROUTING --source \
10.0.77.0/255.255.255.0 ! --destination 10.0.77.0/255.255.255.0 -j \
MASQUERADE

...

So 10.0.77.0/24 is my xen network for all my virtual domains.
It just will work with the default vif-bridge script. 

I also use dnsmasq to serve all virtual machines with a proxy dns server.

Then I agree with my previous poster. Get rid of any network manager.
Install wpasupplicant for your wifi and manage the ethernet with
resolvconf.

The authenticity of a Debian install - yep, using debsums proves

Indeed, you're correct. Still, given this debsums behavior:

# ls -al /mnt

drwxr-xr-x 25 root root 4096 Jan  2 19:39 ..

`/mnt/var/lib/dpkg/status' for reading: No such file or directory
debsums: dpkg-query --admindir=/mnt/var/lib/dpkg --showformat=${Package}

And assuming OP invoked debsums exactly as shown (see [1]) - I suspect
that at least / and /var was mounted into /mnt during the check.

 You can force or change the order of the nameservers. /etc/resolv.conf
 even has an option rotate to do round-robin among the listed
 nameservers. What you cannot do is expect the current resolver library to :
 - ask a given nameserver for a given type of queries (e.g. external
 names), and another nameserver for another given type of queries (e.g.
 internal names) ;
 - ask the next nameserver if the previous nameserver replied that the
 requested name does not exist or does not have a resource record for the
 requested type (aka negative answer).
 
  The setup I had (Debian 3.0) worked. Unfortunately smart devices and more
  wireless laptops demanded attention. So I upgraded (clean install) to Debian
  7.0. All I want to do is for all wireless devices to get DHCP from Debian 
  (not
  the router) and query Debian (not the router) for name resolution. Simple as
  that.
 
 Why then are you messing with the router's nameserver ?
 
 If you need to resolve both internal and external names, I suggest that
 you query only the Debian nameserver and configure it to reply to
 recursive queries, either by itself or by forwarding them to the
 router's nameserver.

Not at all.  The goal here is not to make the workstation completely

little more than room background noise level at the ears when seated in
the desk chair.  An acoustically damped 3 sided box with small
front/rear overhangs accomplishes this, in the two ways that matter:

1.  The damping material, whether carpet or acoustical egg crate foam,
absorbs most of the mid and high frequency sound energy generated by the
fans.  These sound waves normally radiate not only out the front/rear
case vents, but also through the thin sheet steel and plastic panels
which tend to resonate at or near these frequencies.  In the stock
configuration the fan noise radiates in all directions, but not uniformly.

2.  Because the sound pressure level of mid/high frequencies drops at a
much higher rate off axis from ear position, any sound energy at these
frequencies not absorbed by the damping material propagates at floor
level out the front and back only.

By absorbing most, then directionally focusing the remaining mid/high
frequency waves, which are now of greatly decreased amplitude due to the
damping material in the overhangs, the noise is barely audible while
seated in the chair.  You must kneel down to floor level to really hear
the fans now.  This solution works without compromising access to the
machine, or compromising cooling capacity.  The T7610 is a true business
workstation, with front-to-back only airflow.  This 3 sided damping
shroud will not work with PCs which have side air intakes, top exhausts,
etc.  This should be common sense to everyone, but not everyone has
common sense, so I'm attempting to head off further me too posts.

I tend to only reply to thread topics of which I am a subject matter
expert.  You made the mistake of assuming that a DIY suggestion implies
amateur knowledge, then proceeded to display your truly amateur
understanding of the subject matter.

I don't post to debian-user that often, but there are folks on this list
who know they can take the information and analysis I present straight
to the bank.  They know the level of expertise and analysis that goes
into each and every one of my posts, even those in which I don't give
the 2-3 page explanation up front, but the short version which assumes
the reader knows a little bit about the subject.

Re: very slow Xorg and/or bash

2014-02-25 Thread Danny
Hi,

I think you are looking for the answer in the wrong place.

Remember that Xorg is totally network aware. When it starts up, it checks your
hostname and resolv.conf file. A bad configuration of these two will slow Xorg
down considerably.

The reason I say this is because very recently (last week or so) I ran into a
few problems with DNS, and whenever I misconfigured one of these files
Xorg would take up to 15 seconds and sometimes even more to start. Also, I had
slow logins with terminals. Properly configuring these two files rectified the
problem.

Hope it helps

Danny
