Les packages debian avec dotdeb

Juillet 21st, 2005

J'avais écris un petit truc pour expliquer comment forcer debian à utiliser des packages spécifiques. Mais comme Gui ne tagge (release) plus ses packages , j'ai du changer les informations dans /etc/apt/preferences pour :

# En global
Package: *
Pin: origin packages.dotdeb.org
Pin-Priority: 990

# Pour un package spécifique
Package: php4
Pin: origin packages.dotdeb.org
Pin-Priority: 990

Package: php4-common
Pin: origin packages.dotdeb.org
Pin-Priority: 990

Package: libapache-mod-php4
Pin: origin packages.dotdeb.org
Pin-Priority: 990

Fête nationale française

Juillet 15th, 2005

Oui, ça fait pas trop "récit d'expatrié français en Australie" mais hier, j'étais avec ma copine et des amis sur les bords de Seine pour voir le fameux feu d'artifice du 14 juillet.
Un superbe feu de presque 45 minutes et qui, pour la première fois d'après certains journaux, était lancé depuis la tour Effeil avec comme thème pour cette année le Brésil (année du Brésil oblige)... Ceci étant principalement représenté par les feux de couleurs jaunes et vertes ... Les couleurs de ce pays que j'adore... Grandiose et une belle réussite !

X Drive III from Memup under Linux (2.6)

July 8th, 2005

Just a quick memo for me and other who will get this external harddrive/card reader.

This box contains a 60 go (in fact 56) and can read a few memory card : CF I and II, MS, MS Pro, SD, MMC, IBM MicroDrive, RS-MMC, mini-SD, MS Duo and MS Pro Duo.

As I don't want to reboot under Windows each time I want to use it, here is the procedure to have it working under Linux.

You need a few modules :

- SCSI disk support (BLK_DEV_SD)
-> Device Drivers
  -> SCSI device support
    -> SCSI device support (SCSI [=y])
      ->  SCSI disk support

- Qlogic QLA 1240/1x80/1x160 SCSI support (SCSI_QLOGIC_1280)
-> Device Drivers
  -> SCSI device support
    -> SCSI device support (SCSI [=y])
      -> SCSI low-level drivers
        -> Qlogic QLA 1240/1x80/1x160 SCSI support

- USB Mass Storage support (USB_STORAGE)
-> Device Drivers
  -> USB support
    -> Support for Host-side USB (USB [=y])
      -> USB Mass Storage support 

It should be enough. Recompile kernel/modules. Reboot

Plug the two USB connectors (DON'T forget to plugin both if it is not working with only one because of the lack of energy provided by my laptop).
If you try the command lsusb, you should see that :

Bus 001 Device 008: ID 0d7d:1470 Phison Electronics Corp.

And in /var/log/kern.org, you should get messages :

Jul  8 16:34:18 zoidberg kernel: usb-storage: scsi cmd done, result=0x0
Jul  8 16:34:18 zoidberg kernel: usb-storage: *** thread sleeping.
Jul  8 16:34:18 zoidberg kernel: SCSI device sda: 117210240 512-byte hdwr sectors (60012 MB)
Jul  8 16:34:18 zoidberg kernel: sda: assuming drive cache: write through

Then, you should be able to mount the /dev/sdXX (sda1 for me) partition where you want with the command :

mount -t vfat /dev/sda1 /mnt/external

Or add in the /etc/fstab this line :

/dev/sda1	/mnt/external			vfat    rw,user

Les eurodéputés rejettent la directive sur le brevet des logiciels

Le Parlement européen a rejeté définitivement, mercredi, la directive très controversée sur les brevets des logiciels, en votant en seconde lecture contre le texte soutenu par les Etats membres et la Commission européenne avec 648 voix contre 14 !!!(AFP)

L'Europe pour laquelle j'ai voté OUI a bougé. J'en suis très heureux.

Mass DNS Test

July 3rd, 2005

Imagine that you are dirty with your DNS server. You make some modifications very often and you are not sure when your DNS server is up, RFC and running. Here is a little script which will automatically test some domains and send emails in case of error.

In order to test domains validity, I use DNSdoctor (http://www.dnsdoctor.org/), a fork from Zonecheck (http://www.afnic.fr/outils/zonecheck), a tool developed to perform verifications on the quality of the configuration (it is mandatory with a .fr to have the domain correctly configured). DNSdoctor exists with a few GUI :
- the web interface - http://demo.dnsdoctor.org/
- a classical application using GTK
- a command line application

Of course, I am using the last one to perform the automatic testing system.

As DNSdoctor has been made using Ruby, I made this script with this language (I don't want to have to install python for this script). It will call the DNSdoctor with the appropriate parameters. If an error is detected, it will send an email associated to the domain in the configuration.

If an error occurs, this kind of email will be sent :

ZONE  : ledru.info.
NS <= : akira.ecranbleu.org. [195.137.249.60]
NS    : radium.meaweb.com. [83.217.68.103]
NS    : trunks.ecranbleu.org. [195.137.249.61]

 | Ref: IETF RFC1035 (p.32 4.2. Transport)
 |   The DNS assumes that messages will be transmitted as datagrams or in
 | a byte stream carried by a virtual circuit. While virtual circuits can
 | be used for any DNS activity, datagrams are preferred for queries due
 | to their lower overhead and better performance.
