Problemas con Nagios y NRPE

2011-02-04 Thread Raydel Hernández Martínez

Hola lista, hace varias semanas monté un Nagios para monitorear varios 
server, servicios, router, switch, etc, y todo me funcionó a la 
perfección. Ahora lo monté en un server en producción, y todo me va 
funcionando hasta el momento, excepto, que cuando configuro las 
plantillas para monitorear un Host remoto, usando NRPE, el nagios me 
devuelve en la página de administración algo como esto en los servicios:


NRPE: Command 'check_load#' not defined

Estoy usando la version 3.2.3 de Nagios, la versión 1.4.15 de los 
plugins de este, y la version 2.12 de NRPE.
Ya he revisado de arriba abajo las configuraciones de los ficheros donde 
especifico los host, servicios, y los comando en el fichero nrpe.cfg en 
el server remoto, y todo esta como debería estar según toda la 
documentación que he encontrado en internet, y por los ficheros de 
configuración que salvé de la configuración anterior que estuve probando 
en un server de prueba.


Algo interesante que sucede es que ejecuto por ejemplo en el host que 
gestiona nagios este comando:


/usr/local/nagios/libexec/check_nrpe -H 192.XXX.XXX.X -c check_load

(192.XXX.XXX.X) Es la IP del host remoto que quiero monitorear.

Y me devuelve el resultado de manera satisfactoria:

OK - load average: 0.01, 0.01, 0.00|load1=0.010;15.000;30.000;0; 
load5=0.010;10.000;25.000;0; load15=0.000;5.000;20.000;0;


Pero sin embargo en la web de nagios, me muestra el molesto error de:

NRPE: Command 'check_load#' not defined

La comunicación entre el Nagios-Server y el host remoto funciona bien, 
según el comando de comprobación:


/usr/local/nagios/libexec/check_nrpe -H 192.XXX.XXX.X

Que me devuelve la versión de NRPE, en este caso esta es la salida:
NRPE v2.12

Lo que descarta que los firewall que están en cada server, estén 
bloqueando tanto las conexiones Input como Output.


Alguna sugerencia al respecto...
Gracias de antemano.

 NRPE: Command 'check_load#' not defined
Buenas

Según lo entiendo yo te esta diciendo que no encuentra en el host el
comando check_load#

El comando en consola sale bien, porque el host tiene definido en su
fichero el check_load PERO NO el check_load#. Luego el cliente esta ok.

Ahora cuando tu llamas desde el servidor, le estas pidiendo que te diga
el resultado del check_load# el cual no existe. Para confirmarlo ejecuta
esto desde el server:

/usr/local/nagios/libexec/check_nrpe -H 192.XXX.XXX.X -c check_load#

Si te da error ( que lo hara) ya sabes que tienes que hacer. Revisar en
el servidor la plantilla de ese host y eliminar el # al final de la linea.

Si me pasas esa configuración la podemos revisar.

Un saludo y suerte

Dudas tontísimas sobre instalación

2011-02-04 Thread SM Baby Siabef

¡Hola compis!

Me he hartado de buscar en Google pero no he encontrado una explicación
clara sobre unas dudillas que le han surgido a un amigo mío que plantea
instalarse Debian testing.

Él tiene exactamente el mismo ordenador que yo (Aspire 5810T). Como sabréis,
a mí no me fue la tarjeta de sonido, pero él, que tiene Ubuntu Lucid, sí le
fue a la primera y ni tuvo que instalarlo ni nada (aunque Ubuntu le instaló
pulseaudio... que era como se solucionaba conmigo).

Bueno, la duda no es esa. Tiene separado su disco duro en tres particiones,
a saber, la clásica swap, una que tiene el directorio raíz (/) y en la
tercera por separado tiene a /home.

La duda reside en qué pasará con /home. Tiene miedo al tema de los permisos
y si se instala que no le deje acceder a los archivos y, ya que tiene allí
archivos de configuración de programas usados en ubuntu, si eso puede llegar
a influir negativamente en la instalación de Debi. ¿Podría acceder sin
problemas a sus carpetas y archivos sin ningún problema de permisos o tiene
que tomar alguna precaución en especial? ¿Qué tendría que hacer con los
archivos de configuración?

No he sabido contestarle ninguna de las dos y me he hartado de buscar y no
encuentro una respuesta clara. He leído el manual de Debian en la guía de
referencia pero no aclara nada de esto o yo no me he enterado muy bien...

Un saludo a todos. Agradezco de antemano cualquier respuesta :)

Buenas

No va a tener muchos problemas en un principio. Se instala el sistema y
le dices que monte el /home (sin formatear) en el /home ( claro XD).
Crea el mismo usuario en el sistema y listo.

Ahora bien, si tiene las mismas aplicaciones que tiene configuradas en
ubuntu, debería seguir todo igual. A lo peor alguna le da error
(Librerías que no tenga instaladas o que sean nuevas y no estén en
squeeze), pero seguro que podrá resolverlo con google XD.

Mi recomendación si puede es que instale debian sin borrar ubuntu. Lo
testee y si todo va ok, para adelante. Pero claro para eso debe tener
espacio de sobra.

Un saludo y espero que te sirva.

Re: Problemas con Nagios y NRPE (Solucionado)

2011-02-04 Thread Raydel Hernández Martínez

Hola lista, el problema del nagios y nrpe ya lo he solucionado gracias 
al amigo jmramirez, que me dio un norte de lo podia ser el problema, y 
resulta que era una sencillez, un caracter de más en el comando:


define command{
command_namecheck_nrpe
command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}


Que al fina de la línea command_line, tenía el caracter # junto al 
parámetro $ARG1$, en el fichero command.cfg del server nagios.


Saludos, y gracias a todos.

Si quiere instalar Debian y mantener Ubuntu, yo mantendría cada /home 
con su distribución, es decir, Debian con su /home (no tiene por qué 
ser una partición separada) y Ubuntu con la suya.

 ¿Podría acceder sin problemas a sus carpetas y archivos sin ningún
 problema de permisos o tiene que tomar alguna precaución en especial?

Podrá acceder, pero los permisos quizá le bailen o tenga que ajustarlos 
para dar permiso de acceso al usuario de Debian. 

 ¿Qué tendría que hacer con los archivos de configuración?

¿Te refieres a los archivos de los programas de la /home de Ubuntu? Yo 
no los compartiría, que no comparta la /home. Debian puede usar 
programas y/o configuraciones distintas y le puede causar más de un dolor 
de cabeza.

En resumen: 

- Acceder a la /home desde Debian, sin problemas.
- Compartir el directorio /home entre distintos usuarios de distintas 
distribuciones, mala cosa.

Camaleón, quiere desinstalar Ubuntu y poner Debian encima,. Es decir,
instalar debian en el sistema raiz / y dejar /home tal cual. Perdón si
no me expliqué bien... Por lo que entendí de lo que has escrito, tendría
algunos problemillas con los permisos (me lo esperaba). Con los archivos de
configuración, me refiero a .wine, .aptitude, .gconf2 y demás

Pues mejor que deje la partición /home de Ubuntu pero que cree un /
home para Debian, independiente. Con la capacidad de los discos duros 
actuales, supongo que no tendrá problemas de espacio.

Buenas...

Yo alguna vez lo hice y no tuve mayores complicaciones. por lo
menos si las tuve no las recuerdo.

Siendo ubuntu y debian bastante parecidas, creo que los paquetes serán
casi las mismas versiones y cogerán las configuraciones del otro
/home. Puede que haya alguno rebelde, pero si no ha metido/compilado
cosas raras debería funcionar. Si estoy confundido corregidme, por favor.

De todas formas, creo que es mas conveniente para el amigo del
compañero. Montar un nuevo /home ( como comenta camaleón) y luego que
vaya copiando poco a poco, para terminar eliminando su viejo /home de
ubuntu. Sobretodo si es demasiado importante la información.

gracia o no! La opcion clara, es seguir o abandonar la lista.


 PD: Porque no tomas de ejemplo a personas como Camaleon que siempre esta
 dispuesta a colaborar con su ayuda!!!


Seguramente, por que esta es una lista de Debian y aqui nos regimos
con las normas de Debian y no con ningun ejemplo en particular.

Supongo, por tus comentarios que eres nuevo en la lista, y quisiera
informarte; que esto no es un foro, aqui tenemos las normas para
mantener el orden de las preguntas/respuestas; el lexico colegas,
men y cualquier otro vulgarismo, no son bienvenidos por que no son
expresiones regulares del Castellano y pretendemos utilizar un
lenguaje claro para todos; esto esta en las normas, quizas deberias
leerlas antes de comentar.

Re: Debian Lenny, ALSA y archivos de configuracion

2011-02-04 Thread Bruno

  Me gustaría cuales son los archivos de configuración que tengo que
  atacar para que todo funcione automáticamente o casi. xD
 
 No me queda claro el problema que tienes actualmente :-)

El problema que me gustaría solucionar, no siendo de mucha gravedad, es
la desapareción del applet Gnome que controla el sonido y la inutilidad
del puerto (jack) que existe en el panel frontal del pc que esta
conectado al puerto de sonido en la placa.

 
 ¿Tienes sonido, se carga el applet de gnome, te falla alguna opción 
 (cascos, micrófono, conmutar entre cascos/altavoces, valores no 
 almacenados tras cada sesión...?)

Tengo sonido. Sólo se reproduce a través de los altavoces que están
conectados al jack de salida maestra de sonido (verde) y el jack negro,
que no tengo ni idea de para que sirve.

¡Hola compis!

Me he hartado de buscar en Google pero no he encontrado una 
explicación clara sobre unas dudillas que le han surgido a un amigo 
mío que plantea instalarse Debian testing.


Él tiene exactamente el mismo ordenador que yo (Aspire 5810T). Como 
sabréis, a mí no me fue la tarjeta de sonido, pero él, que tiene 
Ubuntu Lucid, sí le fue a la primera y ni tuvo que instalarlo ni nada 
(aunque Ubuntu le instaló pulseaudio... que era como se solucionaba 
conmigo).


Bueno, la duda no es esa. Tiene separado su disco duro en tres 
particiones, a saber, la clásica swap, una que tiene el directorio 
raíz (/) y en la tercera por separado tiene a /home.


La duda reside en qué pasará con /home. Tiene miedo al tema de los 
permisos y si se instala que no le deje acceder a los archivos y, ya 
que tiene allí archivos de configuración de programas usados en 
ubuntu, si eso puede llegar a influir negativamente en la instalación 
de Debi. ¿Podría acceder sin problemas a sus carpetas y archivos sin 
ningún problema de permisos o tiene que tomar alguna precaución en 
especial? ¿Qué tendría que hacer con los archivos de configuración?


No he sabido contestarle ninguna de las dos y me he hartado de buscar 
y no encuentro una respuesta clara. He leído el manual de Debian en la 
guía de referencia pero no aclara nada de esto o yo no me he enterado 
muy bien...


Un saludo a todos. Agradezco de antemano cualquier respuesta :)
Yo creo haber hecho lo que dices en alguna ocasión, Fedora a Debian o 
algo así (lo que sucede es que ya llevo mucho tiempo usando Debian) y no 
veo que haya problemas en que dejes la partición /home sin formatear y 
luego le indiques al instalador de Debian que use dicha partición para 
el /home.


Para asegurarte, copia todos los archivos de configuración dentro de tu 
/home a un disco externo por precaución. Los programas no varían mucho 
en cuanto a la ubicación de sus  preferencias y puede ser que incluso en 
algunos casos detecten el cambio y actualicen la configuración solos.


Solo ten en cuenta que puede variar el uid de tu usuario de Ubuntu con 
respecto al de Debian. Es solo cuestión de hacer un chown a tu /home y 
poner tu usuario de Debian como propietario antes de iniciar por primera 
vez la interfaz gráfica.


Claro que este mensaje no tiene garantía es solo una recomendación, no 
se aceptan reclamos :-D

Vale, en cuanto al applet de sonido, puedes probar algunas cosas:

1/ Iniciar sesión con un usuario recién creado para ver si le carga el 
applet.

2/ Intentar añadir el applet, si te aparece como opción (botón derecho 
sobre el panel / añadir al panel / control de volumen).

3/ Reiniciar el servidor alsa para ver si te saca algún error.

Sobre los jacks de audio... los del panel frontal suelen ser para la 
salida de cascos y/o entrada del micrófono, pero tendrás que comprobarlo 
(en el manual de la placa lo pondrá pero si el equipo no lo has montado 
tú puede ser que haya algún cable suelto o no conectado...). 

Si no te funcionan ni los casos ni el micro -cuando se supone que 
deberían hacerlo-, seguramente tengas que indicarle a alsa el modelo de 
tu tarjeta de sonido para que sepa cómo configurar las entradas/salidas.

Disculpa mi ignorancia. Cuando ejecute el script *alsaconf*, finalizando

Cuando me vi en la necesidad de instalar dos distribuciones en la misma
maquina pense en el mismo problema, pero lo que hice no es algo demasiado
complicado...

Uno siempre tiene una distribucion favorita (que es la que más usara) y
una de prueba... no encuentro otros motivos para instalarme mas de una
distribucion...
Asi que tengo una sola particion /home que será utilizada por mi sistema
principal... a la distribucion secundaria no le doy una particion para
/home, asi que mi /home estará en la misma particion de la raiz...

Entonces lo que hago es crear enlaces simbólicos desde el /home/usuario de
la distribucion secundaria a los directorios de mi particion /home principal
Para explicarme mejor dejo un ejemplo:

Distro secundaria: /home/usuario/Descargas/ apunta a
/particionHome/usuario/Descarga de la distro Principal
Distro secundaria: /home/usuario/Imagenes/ apunta a
/particionHome/usuario/Imagenes de la distro Principal
Distro secundaria: /home/usuario/Videos/ apunta a
/particionHome/usuario/Videos de la distro Principal

De esta forma en cada home tendras las configuraciones para cada distro sin
que una moleste a la otra y los directorios de tus archivos seran los mismos
en ambas  home

Una Advertencia:
No guardo nada directamente en /home/usuario/
Lo tengo ordenado cada cosa en su directorio de tal manera que esten mis
archivos disponibles en ambos home sin crear confusiones...

Espero haberme explicado correctamente ;)

Bendiciones y exitos a todos!

 evento/grabación. En este sentido, conseguimos interesante

  El streaming de audio como para una radio no es
 problema. El reto viene con video streaming ya que existen
 varios contenedores, codecs de audio y video.
  
  Hemos visto que podríamos configurar la escena
 utilizando solamente vlc tanto en el cliente como en el
 servidor. Pero nos gustaría dejar el servidor configurado
 permanentemente para que reciba streams fuentes de los hosts
 de una subred específica y que el resto de los usuarios se
 conecten a este. Incluso, este servidor podría ser fuente
 de otro servidor repetidor en otra localidad.

 fuentes, servidores de streams de video en modo relay y
 usuarios con diversos sistemas operativos.

Saludos Jhosue y gracias por la orientación.

Estuve revisando el portal http://www.accessgrid.org/; y me parece muy 
interesante el servicio.

Entiendo que es posible crear un nodo en mi localidad para luego formar parte 
de la red de nodos (grid) a través del portal.

Creo que para este requerimiento que tengo no aplicaría. Sin embargo, 
definitivamente es una solución para poder ofrecer clases en línea que por 
demás es otro de los proyectos que estamos impulsando y que hemos apoyado con 
servicios como www.wiziq.com y evo.caltech.edu.

¿Conoces alguna lectura que oriente la instalación de un nodo con Debian?

Gracias nuevamente.

secundario y es el que debería funcionarte con normalidad. Y supongo que 
al crear el archivo /etc/asound.conf lograste cambiar la posición de 
las dos tarjetas y por eso ya tienes salida de sonido por el adaptador 
VIA ¿no?

Pues ejecuta los pasos (1-5) del enlace que te he puesto para ver si 
puedes afinar la detección de las entradas/salidas definiendo un modelo 
de tarjeta para que lenny te las reconozca todas correctamente.

 ¿Me pregunto de donde sacarás tanto tiempo para responder a todos
 nosotros en esta lista...? ;-)

Estamos configurando un servicio de streaming en vivo

y de archivos en el que un equipo fuente pueda transmitir a
otro servidor al que se conectarían los usuarios para ver
el evento o grabación.

Hemos revisado varios programas servidores como

icecast2 y ffserver, así como algunos programas fuentes
como vlc y ffmpeg.

La intención es que tanto usuarios de linux como ms

guindows y mac puedan visualizar via página web el
evento/grabación. En este sentido, conseguimos interesante
el flowplayer.

El streaming de audio como para una radio no es

problema. El reto viene con video streaming ya que existen
varios contenedores, codecs de audio y video.

Hemos visto que podríamos configurar la escena

utilizando solamente vlc tanto en el cliente como en el
servidor. Pero nos gustaría dejar el servidor configurado
permanentemente para que reciba streams fuentes de los hosts
de una subred específica y que el resto de los usuarios se
conecten a este. Incluso, este servidor podría ser fuente
de otro servidor repetidor en otra localidad.

Alguien ha tenido alguna experiencia similar?: varias

fuentes, servidores de streams de video en modo relay y
usuarios con diversos sistemas operativos.

la infraestructura estaría basada en debian squeeze.

Gracias nuevamente!

Estuve revisando el portal http://www.accessgrid.org/; y me parece muy 
interesante el servicio.

Entiendo que es posible crear un nodo en mi localidad para luego formar parte de la 
red de nodos (grid) a través del portal.

Creo que para este requerimiento que tengo no aplicaría. Sin embargo, definitivamente es una 
solución para poder ofrecer clases en línea que por demás es otro de los proyectos que estamos 
impulsando y que hemos apoyado con servicios como www.wiziq.com y

¿Conoces alguna lectura que oriente la instalación de un nodo con Debian?

mc: los problemas de copiar lo que se ve...

2011-02-04 Thread Walter O. Dari


Hola gente:

Sólo un comentario a un problema que me tuvo loco por un par de horas.

Terminaba de reemplazar un servidor con Ubunto por uno nuevo con Debian 
Squeeze 64. Para no crear todos los usuarios a mano, copie los usuarios 
y grupos de passwd, group, gshadow... y también un montón de 
configuraciones más de /etc


Cuando comienzo a hacer algunas pruebas para comprobar que todo 
funcione, intento ingresar con uno de los usuarios a traves de ssh (en 
la red local) y me daba continuamente error de autenticación.
Entraba con mi usuario y no tengo problemas (a este lo había creada 
durante la instalación), cualquiera de los demás no ingresaba.
Vuelvo a entrar por ssh con mi usuario y una vez en el servidor pruebo 
cambiar a otro con  su - usuarioNN  y me daba el error...


No puedo ejecutar /bin/bash : No existe el fichero o el directorio

Revisé permisos, busqué en Google, revisé cada uno de los .bash* para 
ver si había problemas ahí y nada.


En una de las tantas veces que abrí el /etc/passwd (usando vim), y 
recorriendolo de arriba abajo, veo que en una de las líneas el cursor no 
quedaba después del último caracter, sino desplazado bastante a la 
derecha... con sorpresa descubro que todos los usuarios que había 
copiado tenían un montón de espacios luego del último caracter.


En ese momento me dí cuenta lo que había pasado:
En realidad no copié los archivos passwd y los demás directamente, lo 
que había hecho fue abrir los antiguos con el mcview (del mc), marcaba 
con el mouse pulsando la tecla Shift las líneas que me interesaban y 
luego las copiaba en otra consola donde tenía el archivo del servidor 
nuevo abierto con vim, pulsando el botón del medio del mouse.
Esto hace que se copie todo el área seleccionada en el mcview y no sólo 
el texto, por eso me había copiado espacios al final de las líneas.


Por suerte, el passwd fue el único que copié de esta forma. A los demás, 
sólo por casualidad, los habría con less y luego copiaba de la misma 
forma que el anterior, pero con less no fabrica espacios donde no los 
hay.. por suerte.


En fin, me retrasó unas cuantas horas este inconveniente, ahora estoy 
contento porque lo descubrí. Estuve a punto de crear todos los usuarios 
uno por uno y después ponerles los UID que le correspondían a cada uno, 
y me hubiera llevado otro montón de tiempo más.


Bueno, es para que lo tengan en cuental, a lo mejor ya la mayoría lo 
sabe, pero a mí en 5 o 6 años de trabajar con Linux es la primera vez 
que me sucede.


Espero les sirva.

Saludos,
 .-.   Walter

Atualização de versão do Debian em servidor Samba+LDAP

2011-02-04 Thread Welington R. Braga

Salve todos,

Tenho um servidor samba em produção autenticando pom LDAP e
funcionando muito bem. O único problema é que ele ainda está usando o
Debian Etch. O Squezee está prestes a sair do forno e antes que isso
aconteça eu gostaria de atualizar para o Lenny que é a estável atual.

A dúvida que gostaria de compartilhar com os colegas é: Ao fazer esta
atualização, há algum impacto negativo no servidor. Tipo: Os clientes
deixaram de autenticar no domínio, por exemplo, perder as
configurações etc?

Em fim, alguém já fez esta atualização?

firewall debian

2011-02-04 Thread villani

Boa tarde,

Preciso tirar umas dúvida, estou criando um firewall no debian,
preciso tirar a dúvidas das seguintes situações:

*Para habilitar os módulos do Kernel, quais devo habilitar, claro que
tem os modulo de segurança, roteamento de pacote, tem alguma lista que
eu poça ser ha tabela de todos os modulos??

por exemplo:
echo 1  /proc/sys/net/ipv4/ip_forward
echo 1  /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
echo 1  /proc/sys/net/ipv4/tcp_syncookies

*E os módulos do iptables, mesma pergunta, tem uma lista de todos os
módulos?

Por exempllo:

modprobe ip_conntrack_sip
modprobe ip_conntrack_ftp
modprobe ip_conntrack_irc

Aguardo fazendo um favor.

Att.

Re: Oh no, not partitioning again!

2011-02-04 Thread Dr. Ed Morbius

on 20:32 Thu 03 Feb, PMA (peterarmstr...@aya.yale.edu) wrote:
Hi List.

I plan to install Squeeze pretty soon, and am reviewing
my old decisions re disk partitioning. I will mainly resize
proportionally to my 'df -k' output's Used column.

But two items puzzle me:
/srv I gather this is important to have, but I have yet
to find anything *in* it. Will Squeeze put stuff in
there if I haven't expressly told it too?

Possibly. I've got a /srv/cvs under there, and I couldn't swear how it
got there. Debian Policy will tell you what the rules are. It
references FHS, which states:

http://www.debian.org/doc/packaging-manuals/fhs/fhs-2.3.html#SRVDATAFORSERVICESPROVIDEDBYSYSTEM

This main purpose of specifying this is so that users may find the
location of the data files for particular service, and so that
services which require a single tree for readonly data, writable
data and scripts (such as cgi scripts) can be reasonably placed.
Data that is only of interest to a specific user should go in that
users' home directory.

The methodology used to name subdirectories of /srv is unspecified
as there is currently no consensus on how this should be done. One
method for structuring data under /srv is by protocol, eg. ftp,
rsync, www, and cvs. On large systems it can be useful to structure
/srv by administrative context, such as /srv/physics/www,
/srv/compsci/cvs, etc. This setup will differ from host to host.
Therefore, no program should rely on a specific subdirectory
structure of /srv existing or data necessarily being stored in /srv.
However /srv should always exist on FHS compliant systems and should
be used as the default location for such data.

Distributions must take care not to remove locally placed files in
these directories without administrator permission.

So: yes, Debian packages may create directories here. But not remove
files (without prompting).

As with otehr FHS constructs: the _filesystem_ path must exist, but how
you map this onto your storage is up to you. You could use a symlink,
union mount, or mount additions / external storage here.

On personal systems I generally symlink /srv and /opt to similarly named
directories under /usr/local/.

On production systems, I may do the same, or map these to dedicated
storage where requirements dictate.

/tmp As a rule of thumb -- i.e., special considerations
notwithstanding -- what do you think of making
this the same size as /var?

About 1-2 GB, possibly as tmpfs.

/var on should generally be at least 3-4 GB if allocated separately.
That's just for package archives and ordinary system state. If you've
got additional storage (mail spools, databases, etc.), you'll want to
increase provisioning.

I try to stay on top of actual system usage, prefer separating
partitions, and find myself getting bitten. I'm now suggesting about 1
GB for a separate root partition (independent of /usr /var /tmp /home
and /usr/local), and 10-12 GB for /usr. For root, it's the
proliferation of kernel modules, and the need to be able to have at
storage for at least 2 (and more likely 3-4) kernel + module trees. For
/usr, it's the internationalization and language support for packages.
/usr/share and /usr/lib/ run over 2.5 GB apiece, and that's _with_
localepurge installed.

 I leave it on /, and ask the initscripts to mount a tmpfs of 1GB (or even
 less) on top.  See attached file (/etc/default/tmpfs).  Edit to fit your
 system and needs.
 

Depends on the workload, If you do video editing of large files, or use
application like Blender for large projects, you can end up with several
GB's in /tmp very quickly, if space isn't available the application may
freeze/crash and you don't want that in the middle of an editing
session. Some cd/dvd burning applications can be using /tmp for large
amount of data too, for instance when doing a backup/burn on the fly
with only one dvd drive on the machine. With such workloads using a
separate partition on a separate disk improves performances a lot, if
you go the tmpfs way you'll need loads of ram.
It's almost always possible to easily change the location of the
temporary directory in the applications' preferences though.

Hi list,

I have an external amplifier that can be controlled using the commands
remote_power amp on and remote_power amp off.

I'd like to have ALSA automatically turn on the amplifier whenever
something tries to play sound and to turn it off after some period of
idleness. Is this possible?

 Are you sure the media is ok?

 Yes. Works fine with my macminig4 box.

 That is does the media play ok, can you see the contents from another
 computer. Is your DVD player/recorder OK with dual layer DVD's

 This is somewhat my question: how do I know that ?

 $ apt-cache policy dvd+rw-tools brasero
 brasero:

 dvd+rw-tools:

 Do these versions work with dual layer DVD's?

 Again this is my question. Anyway I used dd and I can copy the iso image:

This looks ok. Doing a file does not reveal anything. However using
hexedit I can find the strings: Apple_partition_map

I didn't realise it was an Apple iso. :(

You may need some Apple utilities if you want to mount it on linux.

why is the RIGHT ALT key ignored?

2011-02-04 Thread jidanni

Why in emacs, iceweasel, etc. is RIGHT ALT ignored? LEFT ALT is
processed as ALT, but RIGHT ALT is treated like I didn't press it.

xev shows that indeed my keyboard is not broken,
KeyPress event, serial 33, synthetic NO, window 0x1a1,
root 0x119, subw 0x0, time 5852895, (169,-14), root:(173,546),
state 0x0, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

So why if both keys are labeled ALT, why is only the left one processed?
What if you treated SHIFT that way?

Wait, even on the console outside of x-windows it's that way! What's
going on?

There, I logged in to an empty vanilla account on the console and it's
that way still.

tool for internet connection test

Hi guys,

I'm having a real problems with my internet provider. I have plenty of
disconnection and slow internet connection. However, my internet
provider claims that everything is OK. Does Debian have some tool
which can be run overnight or so to check for internet speed and/or
count number of disconnection. All I can think of at the moment is
ping -c n which gives me packet loss. Is there some tool dedicated
for this purpose?

thank you

Lubos

If your service is an ADSL one, first check to see what the line sync 
figures are, then look at the downstream attenuation figure.


A low sync may be a sign of high downstream attenuation or it might be 
just a bad once-off connection.


Weather can play havoc with DSL too, bring on the NBN in AU.  All sorts 
of things can effect the quality, or rather lack thereof that we get 
from our Telstra [Hel$tra] owned copper network.


Once you get past those things, you can try pinging your ISP's gateway 
address, then their DNS servers -- if you are getting packet loss to 
these ISP servers, then you know where the problem scope is (local). 
But if they are fine, then it could be beyond the ISP or on one or more 
of their links to the Internet.


Drop-outs can happen often with water in the phone lines / pits or it 
could be bad filters or damaged internal wiring.


There are so many things that could be causing your troubles, hope I've 
given you something to think about and perhaps get some more answers.

Re: tool for internet connection test

Hi Paul,

thanks for that. However, I'm looking for some real time monitoring
that could give me some concrete data which for example a can base my
complaint on. The problem is that the speed varies and is not
constantly slow as well as I'm not constantly disconnected from the
internet. Here are my stats:

Before:

After:

 I just had a problem with my connection. Well actually I upgraded to 6Mb
 service  thought I wasn't getting 6mb. So my ISP pointed me to this test:

 http://speedtest.net

 and I saw I was getting 6.42Mb up and .42Mb down ..

How? I'm just doing: sudo mount /dev/sdX4 /storage #X is always greater than a

Re: tool for internet connection test

Hi Andrew,

I'm on ADSL2. I had constant speed for years and it was always around
6 - 8 Mbps. Suddenly it dropped to 0.3 - 4 Mbps but on average I have
0.9. As you also mentioned I too believe that the weather is to be
blamed.

My Telstra land line had such a nose that I could not make a phone
call. Telstra technician came and said that there is nothing wrong
with it and they charged me $105 incorrect call out fees :-) TPG ( my
current internet provider ) confirmed weak signal but when the
technician came he allegedly did not find any problem. Of course he
did not find anything wrong he was on my premises for 10 minutes and
at that time everything was fine.

1 months ago I tried to ping their IP I think it was web server and I
got around 20% packet loss. I'll try again your suggestions.

thanks

In my experience, it is extremely rare for a Telstra tech to admit a 
fault.  However, I've seen problems disappear after their visits for 
some customers  so they found a fault alright, they just wouldn't 
admit to it.


Incorrect call out fee is a bit harsh, but it is a Telstra charge and 
any ISP just passes this on (typically, if not always).



1 months ago I tried to ping their IP I think it was web server and I

Have a look at smokeping: http://oss.oetiker.ch/smokeping/
It can graph latency and packet loss over time.

Re: tool for internet connection test

Hi Paul,

Before is when I did not have problem and after is what I really would
like to know. What happened that suddenly after years I have
disconnections and slow internet which is sometimes so slow that it
could be considered as a disconnection.

 when you are getting download speeds of 0.80 what does a traceroute show?

I'll try that later and let you know, now I'm on high speed 1.6Mbps :-)

thanks

 Nobody is complaining about 'this sudo/su thing...' whatever thing

That thing is all the noise you've been done in this thread on this

 The whole point is ... We shouldn't pretend Debian is the same as
 Ubuntu.

Ubuntu has not the monopoly of sudo, it's not that hard to understand.

 By giving advice like sudo whatever, we are.

I don't think so. By giving that advice you are only showing you're 
using sudo and nothing more. Anything else is what I call bias.

Re: tool for internet connection test

Hi Paul,

  However, I've seen problems disappear after their visits for some
 customers 

not in my case. It is little bit better now but I think that this is
because is raining less. I have this problem for last 2 months.

 Incorrect call out fee is a bit harsh, but it is a Telstra charge and any
 ISP just passes this on (typically, if not always).

yeah, I refused to pay it. Furthermore I threatened to refused pay for
may phone bill as I'm not getting the service I had payed for. So far
so good and they waived my $105 fee,  but unfortunately this does not
fix the problem :-(

allow/deny user power of the os

hi folks :)

How is the best way to deny and allow by time and date of user/s 
poweroff/reboot system?

This client runs from 08am to 8pm. I have to deny all users reboot or poweroff 
within time, but user/s can reboot or poweroff this system from 8.01pm to 
7.59am.

Thanks!

ISO_Level3_Shift
AKA AltGr
Either that is explicitly set somewhere, or you are using a keymap
(e.g. US_Intl)
that includes it. It should let you type stuff like áéæ©ñµ (altgr+ a,
e, z, c, n, m
respectively), or possibly it is a compose key (e.g. hold altgr and press a and
then e = æ) or a dead key (altgr+a, let go, press e = æ).

Wait, even on the console outside of x-windows it's that way! What's
going on?

On modern setups, X and the Console can share a common keyboard
config. (/etc/default/keyboard with the console-setup package)

   Any ideas?

Yes, one : just another case of undesirable interaction between bridge
and netfilter (aka bridge-netfilter).

If the kernel was built with CONFIG_BRIDGE_NETFILTER=y (Debian kernels
are) and sysctl net.bridge.bridge-nf-call-iptables=1 (this is the kernel
default), then IP packets going through a bridge are passed to iptables
chains, as described in Documentation/networking/ip-sysctl.txt. This is
a nice feature when you want to set up a filtering bridge.

Granted, you don't have any iptables rules related to the bridge.
Indeed, but the description in ip-sysctl.txt is incomplete.
Bridge-netfilter does not actually pass packets to iptables chains but
to netfilter hooks, which in turn passes them to iptables chains - but
not only : it also passes them to conntrack (connection tracking). And
remember that NAT rules can be applied to a connection only the first
time it is seen by conntrack. Here the first time conntrack sees the
ping is when it goes through the bridge from tap4 to tap2. And this
time, there is no NAT operation.

Setting sysctl net.bridge.bridge-nf-call-iptables=0 to disable passing
bridged packets to netfilter shouldf fix the problem.

Some routers provide a logging facility that allows to 1) store the logs 
inside the router itself or 2) send the logs to an internal computer. 
Should you lose connection frequently or modem restarts it will be 
dropped there.

To test the link speed you can first ensure your router is synchronized 
at the right up/down speed and then run any online test available out 
there.

Routing via an OpenVPN tunnel; was message threading ...

2011-02-04 Thread peasthope

From:   Bob Proulx b...@proulx.com
Date:   Tue, 18 Jan 2011 21:12:47 -0700
 I am suggesting that you have such a complicated routing setup that it
 is causing you difficulty and that you should simplify it by some
 method.  You listed five (5!) route commands in your configuration.

Yes; addressing subnets rather than individual machines is better.
Now there is just one route directive in joule:/etc/openvpn/myvpn.conf 
to identify the subnet at UBC.  dalton:/etc/openvpn/myvpn.conf has 
one route directive to identify the subnet at home;  but dalton 
has two other route directives to let the subnet at UBC connect 
to the Shaw FTP and SMTP servers.  The Shaw SMTP server will accept 
a connection only via my home link.  The FTP server will accept a 
connection from anywhere but the tunnel avoids exposing communication 
to the public.  http://carnot.yi.org/NetworksPage.html is updated with the 
details.  For now, I can't think of any further simplification.

From:   Mike Bird mgb-deb...@yosemite.net
Date:   Tue, 18 Jan 2011 21:07:47 -0800
 Once your routing gets that complexicational you might
 want to consider using a routing deamon such as Quagga.

 You could probably use OSPF over the tunnels but we
 prefer to use private BGP, with each office and laptop
 and customer office network a separate private AS.

I'll read about those.  Now that the configurations are 
simplified I might leave them rather than install more 
software. 

Thanks for the ideas.  Avoiding reliance on a DDNS for Joule 
by dropping the remote directive on Dalton was a crucial 
improvement.

 Right. But being the expert you probably won't be asking questions where

 But as is more likely someone asking for advice where the answer is
 sudo whatever are either not experts, and hence it wouldn't have been
 configured when they installed squeeze, and therefore the answer sudo
 whatever won't work, or, they are running Ubuntu where it would work
 BUT as we all know (all together now) Ubuntu is NOT Debian.

 Am I misunderstanding something?


I'm pretty sure that Debian ships with sudo, or at least it did in my recent
Squeeze desktop installation (late November 2010). Sudo wasn't configured (I
ran visudo as root to set it up), but I didn't have to add the package
(which I usually do in any Unix/Linux I use).

I use OpenBSD as well, and it also ships with sudo (again, it needs to be
configured by root with visudo).

Whether you like or hate Ubuntu, it does get one in the habit of using sudo,
and I've continued doing so on all my systems, not just those running Ubuntu
(of which I still have one box).

I've got a system (Lenny, kernel 2.6.26-2-486)that occasionally fails to boot 
fully. The last item noted on the console is 'Activating Swap', then nothing.

I've enabled bootlogd (/etc/default/bootlogd) and verbose mode 
(/etc/default/rcS) but nothing of importance is shown. I've even reinstalled 
Debian from scratch and the issue persists. I've tried different hard drives, 
no change.

Now, here comes the odd part. If I remove the swap entry from fstab, the system 
will still hang at times! If there is no swap being made available to the 
system, how can it still hang? Do the init scripts look for and use any 
partition with a swap partition type?

Also, is it possible the problem is soemthing else but it simply manifests 
itself as a hang at the 'activating swap' part of the boot process? I've 
extracted the Debian initrd and looked through the scripts there and in 
/etc/rcS* on the root partition. Nothing is jumping out at me for a possible 
cause.

How should I proceed to troubleshoot? Any ideas?

Thank you!

Please help me to evaluate flash/ssd life using vmstat -d

2011-02-04 Thread R. Ramesh


All,

 I run a debian firewall on an atom PC running of a 16G flash drive. I 
am trying understand the amount of disk write performed in order to 
understand how long my flash is likely to last. I have two vmstat -d 
information on the flash


   2011-01-31 00:35
   disk- reads writes---

1057928  0 76


Note that the kernel writes do not translate into equivalent size writes 
into the flash. This is because flash has to be always written in 
multiples of erase block units (or write allocation size or some such 
thing). So I like to know how to translate above writes into number of 
erase-block writes. I could simply use number of sectors as the number 
of erase blocks and get a very conservative estimate. This way I get 
136104 erase blocks in 88 hours. Assuming erase block is 512K and flash 
can deal with 10K writes per block before it dies, I calculate 
(16G*1)/(136104*512K)*88 hours of life. This is 211866 hours or 24 
years. Plenty for me.


But, I really do not like being this conservative. So, I like to know if 
the number of writes under the column titled total refers to the 
number of kernel writes in which each write is a single disk IO for 
contiguous group of sectors. If so, I can assume that each such write 
will cause at most two erase-block writes on the flash giving me a life 
of (16G*1)/((9649-2512)*2*512K) * 88 hours. This is 2020165 hours or 
230 years. While I do not need this much life out of the flash, I like 
to know which one is closer.


I have not done any optimization for the flash like aligned partitioning 
and use of tmpfs. However, I have used noatime mount option which 
reduced the number of writes by an order of magnitude or more.

I'd first verify that you are indeed running through the scripts of /etc/
rcS.d and not rc3.d or the like.
Then, since you're seeing the hang whether or not there is a swap, it's 
likely what FOLLOWS checkroot.sh or mountall.sh.  Add console messages to 
the scripts indicating you're exiting one and starting the next.  Once 
you find in which script your hang is located, comment the ^%^% out of 
it to locate the command.  Then follow your nose ;)

What kind of URLs is your application generating?  If your application 
generates links with app/webroot/ in them, then the clients will see and 
use those.

I know mediawiki has roughly a dozen configuration options that control how 
it generates URLs, though administrators rarely have to tweak more than 4.  I 
know a number of Web Application frameworks have URL building features, 
partially to handle the case of URLs that don't exactly match the environment 
the application is tested in.

If you are writing the application, you'll be responsible for how it 
generates URLs.  If not, application-specific support fora would probably be 
a better place to determine how to configure / modify it to generate the URLs 
you need.

Paravirtualization kvm with libvirt

Followings are quotes and my questions, 

,-
| We assume that you have installed the virtio-compatible guest

| virt-manager).
`-

What's the default libvirt package for Debian?

I had always been starting my kvm using command line:

  kvm -m 1024 -hda hda . . . 

I.e., the HD device had already been created, and I never need to
specify any driver before. What should I do to use the virtio 
drive interface?

Moreover, is the paravirtualization only involves network and 
disk drivers? How about mouse? I.e., the copy/paste from/to
host feature, is it possible now?

All in all, is there nice step-by-step how-to for paravirtualization 
Linux guest with libvirt for Debian?

Well, the standard security model for Linux systems doesn't really take time 
into account.  Also, sudo, which can be configured slightly more fine-grained, 
doesn't have built-in support for time-based policies.

You could try something involving a cron job switching between two separately 
maintained /etc/sudoers files, one with permissions for /sbin/shutdown and one 
without.

I think your best bet might be SELinux or AppArmor.  I don't really have any 
experience with either, but I thought they could do time-based roles.  Then 
you could have a role which allowed the access required for /sbin/shutdown and 
only allow certain users to switch into it at certain times, from what I've 
heard.

 Yes, one : just another case of undesirable interaction between bridge
 and netfilter (aka bridge-netfilter).
 
 If the kernel was built with CONFIG_BRIDGE_NETFILTER=y (Debian kernels
 are) and sysctl net.bridge.bridge-nf-call-iptables=1 (this is the kernel
 default), then IP packets going through a bridge are passed to iptables
 chains, as described in Documentation/networking/ip-sysctl.txt. This is
 a nice feature when you want to set up a filtering bridge.
 
 Granted, you don't have any iptables rules related to the bridge.
 Indeed, but the description in ip-sysctl.txt is incomplete.
 Bridge-netfilter does not actually pass packets to iptables chains but
 to netfilter hooks, which in turn passes them to iptables chains - but
 not only : it also passes them to conntrack (connection tracking). And
 remember that NAT rules can be applied to a connection only the first
 time it is seen by conntrack. Here the first time conntrack sees the
 ping is when it goes through the bridge from tap4 to tap2. And this
 time, there is no NAT operation.
 
 Setting sysctl net.bridge.bridge-nf-call-iptables=0 to disable passing
 bridged packets to netfilter shouldf fix the problem.
 

  Thanks a lot! Good explanation. I completely forgot about bridge-nf-* vars.

I'm able to log downstream attenuation from my DSL modem with

  Fresh installation of squeeze here, machine AMD Athlon II x2, board Asus
M4A78LT-M LE with integrated Radeon 3000.

The problem is:
  1)  startx on openbox
  -  Switching between consoles (CTRL+ALT+Fn) make appear a blank screen,
  -  returning to X works (ALT+F7)
  2)  exit from openbox
  -  X closes, but the screen keep blank (black...), for every console
(ALT+Fn doesn't work)!

So what??? Please, a mediacenter/server is unusable without VTs...

This problem arise with standard Xorg installation (xorg-video-ati) and
radeon driver, and now with fglrx drivers

  Thank you,
Pier Paolo.

 All,
 
   I run a debian firewall on an atom PC running of a 16G flash drive. I 
 am trying understand the amount of disk write performed in order to 
 understand how long my flash is likely to last.


[..]

 Note that the kernel writes do not translate into equivalent size writes 
 into the flash. This is because flash has to be always written in 
 multiples of erase block units (or write allocation size or some such 
 thing). So I like to know how to translate above writes into number of 
 erase-block writes.


Assuming you have a standard SSD drive attached via SATA or the like,
then you can't make any association between writes issued by the kernel
and the actual NAND device writes inside the drive. This is all
abstracted by the SSD controller which will have a fancy flash
translation layer to do wear levelling and bad block management.

  

I do not have SSD. I have a USB flash drive - went cheap on this :-)

Regardless of the above, still every write by the kernel has to be 
translated in to NAND writes. I have read in more than one place that 
these writes will be in units of erase-block size regardless of the 
kernel IO size. I am simply trying to map the X kernel writes in to Y 
erase-block writes. Note that I do not map it specific erase-block, but 
to some erase-block. So I only worry about the block counts not the 
block addresses. That is why my calculations are based on total number 
of erase-blocks writes available (= 16G/512k*1 = 32768) before 
the device goes bad. So to me the life of flash is 32768 erase-block 
writes. Now how many hours is it? To answer this, I need to understand 
what vmstat -d prints.


Obviously I want to know how many writes are done by the kernel in a 
given hour (on the average).
Assuming that the flash controller is (very) smart to distribute the 
writes 100% evenly, you calculate the life dividing one by the other.  
Obviously, I do not know how to translate the output of vmstat -d to 
actual disk IO seen by the flash controller. Does it see it as X IOs 
from the total column or as Y IOs from the sectors column? Grossly 
taking each IO as a erase-block write I can calculate the life.


Of course the above assumes that the controller is so smart that it 
makes every one of the 32768 writes available to kernel before it 
declares flash is dead. I need this assumption to abstract the 
underlying controller algorithm.

Set as a compose key?

Does 'RightAlt o c' give you '©', 'RightAlt ' a' give you 'á' etc.?

Or as AltGr (sort of a mode shift), as in RightAlt+r gives you ®.

You can configure it.  The easiest way is to use your desktop
environment to do it.  Otherwise, you have to read a lot on XKB and its
utilities, xmodmap, etc.

That's interesting. I don't think I ever used the right alt key for 
anything,

so I didn't know whether it worked or not! On Win7, you need the old-
fashioned 3-finger salute to change to admin, but I always used the 2 left
keys plus delete. When I did the key configuration that Roger wrote
about, I used the right ctrl key to make a compose key--I don't
have any Windows keys at all on my wonderful IBM keyboards.
I guess I could have used the R-alt. But I don't think I ever used the 
R-ctrl

for anything else either. I like to have a compose key: you can make all
the European diacritical marks, the German ß character, the € sign, the ¢
sign,the British £, fractions (I forget how, but you can).

 This client runs from 08am to 8pm. I have to deny all users reboot or 
 poweroff 
 within time, but user/s can reboot or poweroff this system from 8.01pm to 
 7.59am.

Have cron add and remove users in /etc/shutdown.allow at the desired
times. Possibly comment out the CTRL-ALT-DEL line in /etc/inittab.
