1/30/2016 Problem Restarting Apache2: Solutions

If you're using apache 2 as webserver maybe sometimes you'll have to deal with common problems like vhost, syntax errors, bad configurations. Sometimes is when you edit a file inside /etc/apache2/sites-enabled/file.conf and maybe your edition just didn't accomplish with the syntax so here is how can you check :

1. Make sure that your Apache2 service is up and running.

user@~$sudo service apache2 status 
● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)
   Active: active (running) since Fri 2016-01-29 14:05:16 EST; 14s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 31573 ExecStop=/etc/init.d/apache2 stop (code=exited, status=0/SUCCESS)
  Process: 17063 ExecReload=/etc/init.d/apache2 reload (code=exited, status=0/SUCCESS)
  Process: 30948 ExecStart=/etc/init.d/apache2 start (code=exited, status=0/SUCCESS) 
  ...

If this isn't the output, read carefully the error.
2. Check your systemctl status, this will give you a lot of information.

user@~$sudo systemctl status apache2.service
● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)
   Active: failed (Result: exit-code) since Fri 2016-01-29 13:48:57 EST; 18s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 31573 ExecStop=/etc/init.d/apache2 stop (code=exited, status=0/SUCCESS)
  Process: 17063 ExecReload=/etc/init.d/apache2 reload (code=exited, status=0/SUCCESS)
  Process: 30467 ExecStart=/etc/init.d/apache2 start (code=exited, status=1/FAILURE)

3. Run the apache config test. It is always a good idea to run configtest everytime you make changes to the apache2 config file so that you won't accidentally stop apache2 service

user@~$ sudo apache2ctl configtest
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK

4. Restart the apache service

user@~$ sudo service apache2 stop && sudo service apache2 start

7/03/2013 Introducing sources.debian.net

sources.debian.net is a new service[1] that allows browsing the source
code of Debian packages on the web with syntax highlighting,search through the source code ,with the possibility of adding contextual pop-up messages . It is updated and contains source code for all suites in the Debian archive. It currently uses around 381 GB of disk space for uncompressed source packages and around 83 GB for the source package mirror. It is integrated into codesearch.d.n and the PTS. It was created by Stefano Zacchiroli and the web front-end was written by Matthieu Caneill.

sources.d.nfollows closely the Debian archive in two ways:

it is updated 4 times a day to reflect the content of the Debian archive
it contains sources coming from official Debian suites: the usual ones (from oldstable to experimental),*-updates (ex volatile), *-proposed-updates, and *-backports (from Wheezy on)

2/09/2013 Debian bugs #800000 and #1000000 contest

reading quickly my email i found this

As the bug #700000 mark was turned on February 7th 2013, Debian
developers and contributors need yet another new challenge.

So, for the fourth time, a small contest has been set up. It
is very simple: please place a bet (one per person) about the day bugs
#800000 and #1000000 will be reported.

The winner(s) will be the person(s) placing her|his|their bet as close
as possible to the real moment bug #800000 and #1000000 are reported.

There is nothing to win but the pride of being the person who
predicted our bug report rate for the next months|years, just what
René Mayorga won twice for bugs #500000 and #600000 and an obscure
french DD won for bug #700000.

The bet page is a wiki page: http://wiki.debian.org/800000thBugContest

It will be closed on April 30th 2013 (if I remember doing so!). Bets
will be kept statically until bug #800000 is reported.

Please note that bets for bug #1000000 placed back in 2008 and 2010
are kept on this page. Do not modify that section but record your bet
in "Bets for bug #1000000, placed after bug #700000, in 2013".

4/09/2012 Simple Regexp para rss

Recientemente me encontraba revisando algo de musica de los dj's de defcon{1,2,...19} y sus contenidos,yo en mi afan de tener algo de musica en mi celular deseaba descargar toda la musica de 7 a la 9 para poder descargar la musica o video de alguna CON pasada te dan el link a un archivo rss .

Defcon contents

Eligiendo el rss

Defcon 9 Music

pero resulta que me encontraba con algunos problemas:

1.No tenia Itunes por obvias razones...debian,openbsdetc...

2.No me gusta para nada ese reproductor que se me instala con el gdm si rhytmbox,me parece que va algo lento con la descargar de las canciones,cuando no es eso se me tira todo el i3,Asi que yo viendo esta situacion pense en bash,y acordandome de @hecky y otros personajes que todo se puede hacer con bash!,la unica limitacion es tu imaginacion.

El archivo rss basicamente tiene una estructura ,pero nos centraremos en obtener todo lo que contenga la url de descarga que se encuentra dentro de enclosure:

<enclosure url="https://media.defcon.org/dc-9/music/Defcon_9_Club_Saturday_07_Corrupt_Data.mp3" length="55069064" type="audio/mpeg"/>

si deseas mirar un ejemplo de los rss puede revisar este que es el que yo desee descargar:

https://www.defcon.org/podcast/defcon-9-music.rss

asi que lo primero sera descargar nuestro archivo en cuestion para realizar el filtrado.

wget https://www.defcon.org/podcast/defcon-9-music.rss -O defcon9.rss

despues :

cat defcon-9.rss |grep "<enclosure"|awk '{print $2}'|cut -f2 -d ' " '>urls.txt

y por ultimo descargamos con wget :

wget -i urls.txt

si todo estuvo bien deberia aparece algo como :

y asi podrias descargar las canciones.hubiera podida usar curl y la url pero no recordaba algunos parametros y decidi meterme por el lado largo .Espero les halla gustado el post y si sabes de otra forma de hacerlo pues no dudes en compartir :-P.

pd:Por cierto si deseas ademas de la musica de la 9 la de la 8 y 7 es simplemente el mismo proceso solo que tendrias que usar

>>urls.txt

1/10/2012 debsecan + logcheck + mutt

Este es un post algo un poco triste no pretendo explicarlo por que si quieres saber de que se trata simplemente instalalo en tu sistema a si se vuelve algo mas practico ;) con el blog o por lo menos eso creo, estoy un poco enfermo pero nada que no se recupere con un antigripal,tambien ancioso y contento por que de nuevo retomaremos clases,si clases,parciales,estudio,lindas estudiantes,compañeros,deporte...etc y mucho mas,si usas debian y no conoces debsecan deberias de revisar este lindo paquetito...

debsecan - Debian Security Analyzer analyzes the list of installed packages on the current host and reports vulnerabilities found on the system.

logcheck otro y infaltable en tu lista y mutt por supuesto aunque algunos diran no me gusta me gusta mas alpine,por lo menos yo creo que alpine sienta mejor en obsd,con estos tres paquetitos podrias por empezar a hacer tu posicion mas defensiva aunque siempre deberemos de ser tambien offensivos,en fin los tres representan una herramienta valiosa para subsanar un poco nuestro nivel de paranoia aunque no nos salvamos de esos 0days pero como alguien decia en una revista por ahi,podemos hacerle la vida mas dificil a nuestro atancante que por cierto ya haz tomado en cuenta si tu router,modem...etc tiene el firmware actualizado ojo que no vale de nada de tener tu cajita hardenizada y tener 123456 o admin de password en el router ... asi que si los que leen estas babosadas deberias de pensar primero en tu seguridad y que medidas tomas frente a un posible ataque en vez de atacar...

Hasta la proxima y recuerdo defender antes de reventar.

Nanny "Parental Control for Ubuntu and Debian"

Nanny is powerful parental control though for ubuntu ,we can use it via ppa,i would not say that is the best Parental control,but it is reliable and extremely good for my own use well,as you know i use debian and here we go :-D :

first step:

add ppa repo,you can find info about repo here :
open a shell :

vim /etc/apt/source.list


deb http://ppa.launchpad.net/nanny/ppa/ubuntu lucid main 
deb-src http://ppa.launchpad.net/nanny/ppa/ubuntu lucid main

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 132D48BA

you will get this messages :

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.904SlXc0AT --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 132D48BA
gpg: solicitando clave 132D48BA de hkp servidor keyserver.ubuntu.com
gpg: clave 132D48BA: "Launchpad nanny" sin cambios
gpg: Cantidad total procesada: 1
gpg: sin cambios: 1

after that you might add and install nanny :

aptitude update && aptitude install nanny

configure nanny is pretty simple ,you just will add a list from internet :

remenber nanny is web filtering not pidgin or other software,i hope you enjoy this post and if you know another parental control please comment.

apt-get -f install

2/05/2011 Debian Squeezy Release Party and Live Microblogging

Hi again Folks!

During the last months the Team of Security and Developers of Debian proyect have been working in a Squeezy the next release of Debian Stable,in the maintime in around the world is doing a parties today 5 and 6 of february ,for these today i share the next links ,there you will found all information about the party and your town here,also is starting a party line in the account of Identi.ca/debian .The Debian Party Line is a distributed release celebration. Using mumble we can all voice chat together, on a virtual party line.

Some Details :

who

Debian users and developers.

when

February 5th and 6th.

We will follow the events leading up to the release of Squeeze. Developers who have a view into the process are invited to provide play-by-play commentary. And then we will ring in the new release.

Schedule

February 5th

1:00 GMT - party line officially opens, but this may be a quiet time (check if your sound setup works, etc)

14:00-23:59 GMT - Joey plans to be on the party line during much of this time period, to welcome guests and provide play-by-play of the release process.

February 6th

14:00 GMT - Joey resumes play-by-play if release hasn't happened yet

23:59 GMT - party line probably closes

where

Everywhere there's bandwidth. Mumble needs 10-40 kbit/s outgoing bandwidth, and the same amount incoming for each user who's talking. We hope any reasonable broadband connection will do.

The mumble server is mumble.debian.net. It is located in the UK.

how

See instructions for using mumble.
