¿ldconfig en solaris? No, es crle

Pues así es, lo que generalmente hacíamos con ldconfig en *BSD/Linux con el comando ldconfig lo tenemos que hacer en Solaris con el comando crle porque ldconfig no existe como comando en Solaris, el archivo de configuracion que utiliza crle si que es el /var/ld/ld.config para librerías de 32 bits y /var/ld/64/ld.config, para agregar un directorio donde están las librerías dinámicas hacemos:

crle -u -l PATH_DE_LIBRERIA

tener cuidado con esto, si no ponemos -u (update) se borra el archivo de configuración y se crea uno nuevo, si se borran las rutas por defecto del archivo de configuracion algunos (MUCHOS) binarios no podrán encontrar las librerías dinámicas que utilicen u dejaran de funcionar -_-

OpenBSD Release Song 4.6 “Planet of the Users”

Welcome to the future
One very rich man
runs the Earth with
one multinational
owns your stuff
and owns your birth

Everyone is armless
Personal robots
Do it all for you
Sitting on your slug head
One channel TV
never gonna bore you

CHORUS
Does it sound like a paradise
or a way to die
while alive and a loser
I’m a man from the open past
And I’ll never last
on the Planet of the Users

Everyone is happy
No more government
No more media
Only the Company
Entertains you
while it feeds you

Soylent Green pap
Eating your friends while
shopping, buying
Stupid applications
Obsolete before you try them

CHORUS

Take me back
Take me back
Please
Take me back

Way back in my time
Open source kept
everyone choosing
People knew the insides
Of devices they were using

Hackers had a doorway
Now it’s locked and
dumbed down so much
One button coma
Stop the future truly outta touch

CHORUS

OpenBSD song

OpenBSD song

I want to listen this great song.

Riding the micro wave signal (wpa_supplicant)

¿En alguna ocasión han necesitado unirse a una red wireless desde linea de comandos y pensaron que era algo imposible?

Hace unos días tuve la necesidad de asociar mi dispositivo wireless con una red inalámbrica desde linea de comandos, hace mucho tiempo lo había hecho pero no recordaba exactamente como, el problema aquí fue que la instalación de NanoBSD que tengo en mi maquina Alix no tenia las paginas del manual instaladas, (tengo otra memoria CF de 2G disponible pero no he tenido tiempo de crear la imagen), así es que me instale el FreeBSD en una maquina virtual en la laptop y leyendo y leyendo lo hice de la siguiente forma:

Editamos el archivo /etc/wpa_supplicant.conf

NanoBSD# ee /etc/wpa_supplicant.conf

network={
ssid=”MyHappyNet”
scan_ssid=0
mode=0
auth_alg=OPEN
key_mgmt=NONE
wep_tx_keyidx=0
wep_key0=2218972080
}

Donde:

  1. ssid es el nombre de la red
  2. scan_ssid es la técnica con la que wpa_supplicant escaneara las señales para buscar la red inalámbrica, 0 quiere decir scan mediante broadcast.
  3. mode con este parámetro indicamos: 0 = modo infraestructura (nos conectaremos a un AP), 1 = adhoc
  4. auth_alg algoritmo utilizado para el intercambio de claves, usaremos OPEN pero podría ser SHARED
  5. key_mgmt lo ponemos a NONE para indicar que nos autentificaremos mediante una clave wep
  6. wep_key0 especificamos la clave wep

Teniendo todo esto configurado guardamos el archivo y ejecutamos:

NanoBSD# wpa_supplicant -i ath0 -d -c /etc/wpa_supplicant.conf
Initializing interface 'ath0' conf '/etc/wpa_supplicant.conf'

  1. -i especifica la interfaz de red a usar.
  2. -d Ejecuta wpa_supplicant en modo debug para que podamos ver los mensajes.
  3. -c Especifica el archivo de conflagración que tendrá que utilizar wpa_supplicant.

Si todo sale bien veremos el mensjae State: ASSOCIATED -> COMPLETED en la salida del comando wpa_supplicant que ejecutamos,  y  ya podremos obtener una ip del dhcpd que ejecuta el AP ejecutando el siguiente comando:

NanoBSD# dhclient ath0

para que todo esto funcione a momento de reiniciar lo agregamos al archivo /etc/rc.conf de la siguiente forma:

ifconfig_ath0=”WPA DHCP”

Reiniciamos los dispositivos de red para ver que todo este correcto:

NanoBSD# /etc/rc.d/netif restart

En este momento tenemos todo listo y nuestra tarjeta de red wireless asociada al AP :)

I will to put you into jail bad boy (ezjail)

Ultimamente que tengo bastante tiempo libre (espero que eso cambie pronto) me di a la tarea de escribir un manual sobre ezjail, pensaba poner el manual en este espacio pues mi principal objetivo era convertirlo en un sitio mayormente técnico, pero debido a que el manual quedo algo extenso y además de que ya lo había publicado en otros dos sitios considero que está por demás volver a editarlo aquí, así es que si quieren ver el manual pueden dirigirse a uno de estos dos enlaces:

Lazy people works hard

Keep in mind that this is my first post in english, please if you see something written bad, let me know leaving a comment. well here we go.

some days ago I was very bored and tired at my job enough to do nothing that day, however I remembered that I would had to do one task, I needed to compare two databases to know what tables there was into the first one but not in the other one (each database had lots of tables), I’m a very very lazy person when I have to do humdrum tasks and that was definitely. I wouldn’t had wanted to acomplish that task reviewing table by table. I started to think how to do my task in a diferent way, suddenly an idea through across my mind, I would be able to list the name of all tables from each database then I could put all those names into a table containing only the names and making a SQL statement to group the names I would get group’s name, groups having only one element would be the result that I had been searching, but it all still was lot of work for my laziness, therefore I had to find out another way to solve my problem otherwise I would end doing it by hand and thought to myself “never mind, I never going to do that by hand”. It was the time when I remembered that Unix systems has lots of tools to manage text files maybe I could use something tools. Suddenly I remembered a command line tool called diff, the diff command compare two text files (actually it can be binary files) and show their differences, unfortunatly diff doesn’t do the work exactly as easy as I would like, by example having two files called db_one.txt and db_two.txt whit the name of the tables:

db_one.txt

table1
table2
table3
table4
table7
table9
table10

db_two.txt

table1
table2
table3
table4
table5
table6
table7
table8

Using diff command we would obtain this result:

[espartano@ ~/pruebas/diff]$ diff db_one.txt db_two.txt
4a5,6
table5
table6
6,7c8
table9
table10
---
table8
[espartano@ ~/pruebas/diff]$

but it doesn’t enough good for me, I would have liked a command more straightforward than diff (maybe with patch but I not remembered it in those times), well I had to continue searching a command that just make my work in a easy way, then was when I found the blessed command comm, yes, comm going to solve all my problem because as man page says:

utility comm reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1; lines only in file2; and lines in both files.


having the same two files from the last time:

[espartano@ ~/pruebas/diff]$ comm db_one.txt db_two.txt
                table1
                table2
                table3
                table4
        table5
        table6
                table7
        table8
 
table9
table10
 
[espartano@ ~/pruebas/diff]$

voiala this is the result that I was finding. At those point I wasn’t tired nor bored :) because I learned a couple new things, but I think that I worked more than what was do it by hand.

Only if you insist, this is the way which I would have done with SQL:

[espartano@ ~/pruebas/diff]$ cat db_two.txt >> db_one.txt
 
[espartano@ ~/pruebas/diff]$ cat db_one.txt
table1
table2
table3
table4
table7
table9
table10
 
table1
table2
table3
table4
table5
table6
table7
table8
 
[espartano@ ~/pruebas/diff]$ cat db_one.txt | sed -e s/^/"insert into tablas (nombre) values ('"/g > insert.sql
 
[espartano@ ~/pruebas/diff]$ cat insert.sql
insert into tablas (nombre) values ('table1

Lo que nos traera FreeBSD en su RELEASE 8.0

Ultimamente hemos visto como el equipo de desarrollo de FreeBSD han implementado un gran numero de tecnologías en FreeBSD como es el ZFS y DTrace,  ambos de forma experimental en la pasada liberación de FreeBSD 7.0, pero ¿que nos espera para FreeBSD 8.0? pues aquí una probadita de las características que mas me han interesado:

Construccion en paralelo de Ports

La infraestructura para la construccion de ports desde código fuente se ha incrementado para poder permitir la construccion individual de los ports en paralelo. En la era de las CPU’s multicore esto significa que el tiempo que tomaba construir un port se decrementará drasticamente, ahora por defaul todas las CPU’s lógicas se usaran.

Mejora en el manejo de los dispositivos montados

El problema mas común de panics se daba cuando un dispositivo montado era removido en caliente, en la nueva Release se ha corregido este inconveniente.

Jails V2

Se ha desarrollado el soporte para múltiples IP’s por jail (dentro del jail), soporte para IPV6 y SCTP, además las jails pueden ahora ser restringidas a cierta CPU.

Soporte para Xen en modo Dum-U

Se ha integrado el soporte para Xen, permitiendo a FreeBSD ser usado como sistema “invitando” en versiones reciente de Xen Dum-0.

Nuevo Stack USB

Se revisó y arreglaron muchos problemas con el stack USB y se desarrolló una nueva API para el mismo.

Nueva versión del Scheduler ULE

El scheduler ULE ahora toma en cuenta varios aspectos de las CPU’s para calcular los tiempos de los procesos, como son tamaño de cache, cores, sockets …, resultando en un mejor desempeño.

Virtualización del Stack de red.

la virtualizacion del stack es una extension del kernel para el stack de red, permitiendo mantener multiples instancias independientes del estado de la red, esta caracterisitica permite entre otras cosas la independencia completa de red entre cada jail, incluyendo la posibilidad de tener un firewall independiente en cada jail, interfaces virtuales de red, limitar el ancho de banda, tablas de ruteo diferentes (entre jails) IPSEC, etc etc.

Zero-Copy BPF

BPF es una herramienta utilizada para capturar paquetes de red “crudos” de las capas mas bajas del stack de red siguiendo ciertas reglas de filtrado y envía estos paquetes a alguna aplicación para que los procese, también puede insertar paquetes “crudos” en el stack, la mejora que se le ha hecho a BPF reduce el numero de operaciones de copiado que debe hacer entre la memoria, el kernel y la aplicación que analizara los paquetes resultando en un mejor desempeño en algunos casos.

Estas son solo algunas de las mejoras que tendra 8.0 para una lista mas completa visiten: http://ivoras.sharanet.org/freebsd/freebsd8.html

BSDDay 2009 ¿Argentina? Yeah

Me encuentro con que el grupo de usuarios de OpenBSD [http://www.openbsderos.org/] esta organizando un BSDDay en argentina, cosa que me da un enorme gusto (a pesar de que es en otro país) ya que hasta donde sé es el primer BSDDay latino americano, el evento se llevara a cabo los días 29 y 30 de mayo del 2009, en el Departamento de Computación de la Facultad de Ciencias Exactas y Naturales de la Universidad de Buenos Aires, la entrada sera gratuita pero es necesario registrarse.

de entre las varias ponencias que habrá las que me han parecido mas interesantes son:

  • HammerFS.
  • PF Technologies
  • Assembler on BSD

HammerFS es un sistema de archivos bastante interesante (mas ahora que ZFS pertenece a Oracle) que se esta desarrollando en DragonFlyBSD , entre sus características están, Montaje instantáneo o casi instantaneo, no necesita correr fsck después de una caída, buen performance, no tiene limite de i-nodos, chequeo de integridad de datos, soporte para archivos grandes (mas de un exabyte), etc. Para saber mas pueden leer este documento: [http://www.dragonflybsd.org/hammer/hammer.pdf].

PF es el filtro de paquetes de OpenBSD, no creo que haga falta decir nadamas, para saber mas pueden leer el [FAQ de PF].

Y me llama mucho la atención de que tratara la charla Assembler on BSD, habrá que esperar las diapositivas después del evento.

Más informacion sobre el BSDDay en argentina: [http://www.bsdday.com.ar].

OpenBSD Great Song

I love to hate my PC
But now it’s not so easy
Just wanna get this job done
But these A.M.L. games are dumb

You wanna know the truth?
Intel’s controlling you
And Microsoft is too
But this is nothing new

With A.C.P.I.
This endless mess so corporate
Tangles and angles
In what could be straight forward

Lost connections
Lost my mind
It’s such a waste of time

CHORUS

Now on the motherboard
Where all my life is stored
Playing with garbage there
With rules so unfair

Ruled by A.C.P.I.
Whose heart is so corrupted
Forcing us all to play
Our progress interrupted

Lost connections
Lost my mind
It’s such a waste of time

CHORUS

Yes I’m a user
And I’m not the only one
I’m not a loser
With help from Puffy Tron

And we will find it
The pin in all this heartache
Map our devices
And we know what it’ll take

Lost connections
Lost my mind
Oh Ooh Woah end of line

(bridge)
On and on
Can we all be wrong?
All and all
We are one
Clean the dream
Gone wrong
We are Tron
On and on and on

Instrumental CHORUS (guitar solo)

Instrumental pre-chorus

CHORUS
dumb dumb dumb
