Error Postfix Logwatch (solución)
Feb 20th
Error:
Database files are not up-to-date (probably rehash is needed):
/etc/postfix/virtual: 9 Time(s)
Solución:
Lo primero es asegurarnos que los ficheros de alias a los que apunta postfix, son los que realmente debe buscar. Usaremos el comando postconf para averiguar hacia a donde apuntan. Por ejemplo:
[root@TCSL] # postconf alias_maps alias_maps = hash:/etc/postfix/aliases [root@TCSL] # postconf alias_database alias_database = hash:/etc/postfix/aliases
Si ambos no están apuntando a nuestro ficheros aliases en /etc/, podemos cambiarlo utilizando postconf:
[root@TCSL] # postconf -e "alias_maps = hash:/etc/aliases" [root@TCSL] # postconf -e "alias_database = hash:/etc/aliases"
Ejecutaremos ahora el comando ‘newaliases‘ para generar el ficheros aliases.db.
Como descomprimir un fichero rpm en un directorio
Feb 8th
La descompresión de paquetes .rpm es sencilla, aunque las primera veces cuando no se conoce cuesta un poquito. Pero para eso esta Google para ayudarnos. 
Con nuestra distribución preferida, tendremos un programa llamar rpm2cpio el cual vamos a utilizar para descomprimir los archivos en un directorio, que previamente crearemos y nos situaremos en el.
# rpm2cpio paquete.rpm | cpio -ciduv
Los argumentos que pasamos al comando cpio:
i : Extrae los archivos
c : Formato portable
d : Crear directorios completos
u : Incondicional (reemplaza los archivos si existieran)
v : Muestra los archivos descomprimidos en pantalla
¡Animo!
Richard Stallman de retiro temporal o descanso vacacional
Feb 4th
Pues parece ser que Richard Stallman se ha tomado un respiro, aunque el no desconecta nunca y tarde o temprano contesta a nuestros correos.
Recientemente le escribí y esta es la respuesta:
I am not on vacation, but I am at the end of a long time delay. I am
located somewhere on Earth, but as far as responding to email is concerned,
I appear to be well outside the solar system.After your message arrives at gnu.org, I will collect it in my next batch of
incoming mail, some time within the following 24 hours. I will spend much of
the following day reading that batch of mail and will come across your
message at some point. If I write a response immediately, it will go out in
the next outgoing batch–typically around 24 hours after I collected your
message, but occasionally sooner or later than that. Please expect a minimum
delay of between 24 and 48 hours in receiving a response to your mail to me.If your message is hard to understand or responding takes real work,
the response could take longer.So please wait 48 hours after sending a message before you resend it,
remind me about it, or ask if I have received it. If it has been less
than 48 hours, the absence of a response from me only means you have not
given me time to answer.If you are having a conversation with me, please keep in mind that each
message you receive from me is a response to the mail you sent 24 to 48 hours
earlier, and when writing it, I probably had not yet downloaded your later
mail.If you are in big hurry to speak with me, and one day’s delay would be
a serious problem, you can ask my FSF assistant to phone me. Send mail to
<rms-assist@fsf.org> saying what you would like to talk with me about,
and giving your telephone number. You can also call the Free Software
Foundation office at 617-542-5942 (weekday Boston business hours) and
ask them to phone me on your behalf. If it’s really important, try both!An intermediate measure is to email me your phone number and ask me
to phone you.But if there isn’t enough hurry to warrant phoning me, please don’t bother
the FSF people. The mail you already sent me will reach me before any mail
they could send me now on your behalf. I will respond as soon as I can.If you do not wish to receive this message ever again, please send a message
to rms-autoreply-control@gnu.org with the subject “OFF”.
Otherwise, you might receive a reply like this one up to once a month.
