Gérer les associations entre types de fichier et logiciels sous Mate (Linux Mint Debian Edition)

François Rygaert (aka Suske) — 2012-08-18T13:12:39Z

En demandant un jour d'ouvrir un dossier rempli de vidéos avec Totem, le lecteur vidéo, j'ai involontairement provoqué une modificiation de l'ordre des priorités dans l'usage des logiciels en fonction des types de fichier... Du coup quand dans Firefox/Téléchargements je clique-droit sur un fichier et demande "Ouvrir le dossier contenant ce fichier", c'est Totem qui s'allume au lieu du gestionnaire de fichier. Correction.

Une petite recherche [1] sur les fichiers contenus dans mon dossier perso me permet de lister ceux qui contiennent le mot "totem".

Dans la liste, je repère

~/.local/share/applications/mimeapps.list

. Cela se passe probablement là vu que "MIME" est un acronyme qui représente une méthode pour définir les types de fichiers (leur "mime-type"). J'ouvre donc ce fichier avec l'éditeur de texte. Il contient effectivement quelques dizaines de lignes du type

définition MIME=application;(autre application;)

, classées en deux titres : "Associations ajoutées" et "Applications par défaut".

[Added Associations] ... inode/directory=totem.desktop;caja-folder-handler.desktop; ... [Default Applications] inode/directory=caja-folder-handler.desktop ...

On voit que par défaut c'est bien "Caja" (le successeur de Nautilus dans Mate) qui ouvre par défaut mes dossiers et c'est le cas quand je suis dans "Mate" [2] , mais pas dans Firefox. Dans ce cas-là c'est totem qui est utilisé par défaut et je n'ai pas de possibilité de sélectionner une autre application.

Je modifie donc la ligne pour obtenir

[Added Associations] ... inode/directory=caja-folder-handler.desktop;totem.desktop; ...

A partir de là, c'est Caja qui par défaut ouvrira mes dossiers, mais dans Caja, j'ai toujours l'option "Clic-droit->Ouvrir avec...->Totem".

Je suis content et c'est tout. C'est tout ? Un billet pour "ça" ? Ben oui, visiblement :-p

[1] (via le menu "Rechercher..." ou commande mate-search-tool)

[2] et le clic-droit "ouvrir avec..." me propose bien totem également dans ce contexte-là

Prendre le contrôle de MySQL sous (K)Ubuntu 8.04 "Hardy"

François Rygaert (aka Suske) — 2008-05-29T10:55:52Z

J'avais envie de mettre mon CMS préféré en local sur mon PC familial. L'installation est aisée, le serveur démarre tout seul. Le gestionnaire de base de données (MySQL) aussi. Après avoir copié les fichiers nécessaires là où il faut, j'ouvre donc mon navigateur et je lance, confiant, la procédure d'installation. Après quelques tentatives, impossible de créer une base de données.

Il me fallait certainement créer un compte utilisateur qui aurait le droit de créer une base de donnée. Contrairement à ce que j'espérais, la connexion avec "root" sans mot de passe ne marche pas non plus. Je quitte donc le navigateur pour m'intéresser directement à MySQL...

Vu ma faible maîtrise de la ligne de commande, j'ai d'abord installé le paquet "mysql-admin", disponible sur les dépôts "universe".

Sur Kubuntu, je trouve ensuite un raccourci "Menu K / Développement / MySQL Administrator". La fenêtre de connexion qui s'ouvre me demande :
– server hostname : je mets "localhost"
– port : je laisse 3306
– username et password

Sachant que MySQL a un utilisateur "root" générique, je tape "root" et laisse le mot de passe blanc. Accès refusé. Au fait, je découvre rapidement que tout utilisateur peut se connecter (sans mot de passe), sauf "root". Conclusion logique : "root" a déjà un mot de passe et je ne le connais pas. Par contre, j'ai visiblement besoin du compte root pour créer un utilisateur et/ou une base de donnée pour mon CMS. Bref, le blocage.

Après quelques minutes de recherche sur internet, la solution trouvée ne fonctionne pas chez moi. Il manque un script, je l'installe, mais... la suite de la solution ne fonctionne pas... Retour en local, dans le répertoire /etc/mysql, j'ouvre (en root local...) tous les fichiers qui ressemblent à "nom_de_fichier.conf" et là, je trouve, dans "debian.cnf" :

# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = debian-sys-maint
password = abcdefghij123456
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
user = debian-sys-maint
password = abcdefghij123456
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

L'espoir renait ! Ubuntu est une distribution dérivée de Debian. L'installateur crée si nécessaire des scripts et des fichiers de configuration. Visiblement, dans le cas de MySQL, certains paramètres sont définis par l'installateur, probablement pour remédier à la faille de sécurité potentielle ouverte, sous MySQL, par la création initiale d'un utilisateur "root" avec un mot de passe vide.

Bref, ce fichier de configuration m'indique qu'il existe un utilisateur "debian-sys-maint" qui semble aussi avoir le droit de faire l'upgrade de MySQL. Et l'installateur me dit de ne pas modifier ces données. Je n'y toucherai donc pas.

J'ai alors relancé "MySQL Administrator", en utilisant
– username : debian-sys-maint
– password : abcdefghij123456 [1]

Youpie, ça passe et j'ai désormais le droit d'accéder à "User Administration". La, je sélection le user "root", je lui donne un nouveau mot de passe et je retourne à l'installation de mon CMS préféré. Cela marche !!

Je devrais probablement créer un autre utilisateur pour ne pas configurer mon site avec une connexion "root" sur MySQL mais ça, c'est une autre histoire ;-)

Après coup et par curiosité, j'ai recommencé la configuration de mon CMS en utilisant le user "debian-syst-maint", sans succès. Si c'est un souci de sécurité qui est là-dessous, cela semble logique : le syst-maint peut accéder au système mais pas au contenu...

Enfin bref, si vous passez par là dans les jours qui viennent et que le PC familial est connecté, vous pourrez voir que tout cela fonctionne désormais très bien en retrouvant ~~ce billet~~ mon CMS préféré sur http://suske.no-ip.org ;-) (màj du 23/01/2011 : cela fait longtemps que le serveur tourne ailleurs que à la maison :-) )

[1] Le mot de passe réel diffère un peu mais comme on ne doit pas divulguer ses mots de passe, j'en ai inventé un autre ;-)

Si des experts passent par ici, qu'ils n'hésitent pas à signaler toute erreur dans ce texte : je ne suis qu'un bidouilleur expérimenté après tout...

Installing (K)Ubuntu 6.10 "Edgy" (AMD64) on a HP Pavilion DV5137EU

François Rygaert (aka Suske) — 2006-11-13T22:08:36Z

Updated on 7/12/2006: see text in italic

My first test was with Ubuntu 6.06 LTS "Dapper". See here for the know-how of that first experience....
After the first reboot, using the wired Ethernet connection, you'll need to install the Wifi firmware of the Broadcom chipset: installing a software, downloading a file and executing a command... It will be OK. For Ubuntu, you'll also have to edit a file and install another software. Explanations.

For those coming here only for that, this the Ubuntu wiki page giving the explanation: SEE HERE.

Hardware

I resume: things not mentioned in the table are working from the start [1] .

Item	Data	Comment	Details
Battery	6-cell Lithium-Ion (Li-Ion)	full charge gives max 150 min (Kubuntu) to 180 min (Ubuntu) autonomy	Ubuntu takes advantage here
Video Graphics	ATI RADEON® XPRESS 200M IGP graphics	Works	3D not tested
		S-video TV out	Not tested yest
Fax/Modem	High speed 56K modem	Not tested yet	Seems to be recognized
Wireless Connectivity	54g™ 802.11b/g WLAN	Works	Firmware and software to install . I'm using Wireless Assistant with Ubuntu and KNetworkManager with Kubuntu.
	One ExpressCard/54 slot (also supports ExpressCard/34)	Not tested	I don't know what it is :-)
External Ports	1 VGA port	Works
	1 IEEE-1394	Works
	Remote control infrared port (Remote Control optional)	Not tested
	Cable docking connector	Not tested
TI media cards reader	Texas Instrument (doesn't play the Open source game...)	Doesn't work	Seems to exists some drivers. I've not searched a lot...

Starting up

The laptop is configured to start on a bootable CD/DVD if present. So, set the power on, open the disc and set the power off immediately. Set the (K)Ubuntu for 64 bits PC in the case, close it and set the power on again. You won't even see a vindoz logo :-) . Put your network cable in the ethernet port and connect it to your router, assuming you have one.

(K)Ubuntu live

The live (K)Ubuntu is booting and it is working good: keyboard, screen, graphic card, sound, pointer, usb mouse, usb stick and wired ethernet connection were OK. Wifi connection was lightened but did not work. In fact, the wifi driver is integrated in the kernel but you have to give him a firmware before more... Convinced ? You want to install ? Click on the Install desktop icon...

Partitioning the hard drive

1. If you wan to have a full Linux laptop

"Next, next, next" installation process. You also will have to set a few informations of course (user name, and so on). It takes about 20 minutes and no trace of another OS will remain. Go to next main title.

2. If you want to keep a wildows OS on the computer

See my first text about this laptop.

Then, begin the next, next, next install... And restart.

Having the integrated wifi card to work

The BCM43xx driver is integrated in the kernel from version 2.6.17, which is the one for this version of (K)Ubuntu. Great. However, if the distribution ships the driver, it doesn't integrate the... firmware of the chipset: this one is not free... So you'll have to :
– install the bcm43xx-fwcutter firmware extractor : use synaptic
– KUbuntu: install the "KNetworkManager" tool (for later): use synaptic
- Ubuntu: install the "Wireless Assistant" tool (for later): use synaptic [2]

– download the wl_apsta.o firmware to /home/your_name
– In a terminal, run the command
sudo bcm43xx-fwcutter -w /lib/firmware wl_apsta.o
– restart the computer (logoff, login is perhaps enough or even network restart - I don't know: I use to restart the computer, don't you know why ? Tips are welcome...)
– Take the wired connection off. THE WIFI WILL SOON DO IT :-)

Then, you'll have an integrated Wifi card "on". Under Ubuntu, to have the network icon working, right-click on it, properties and manually set "eth1" in the interface "name" box. I don't know why but Ubuntu doesn't list the eth1 automatically.

– Ubuntu

Run Wireless Assistant (root password needed) => available networks are listed
Right-Click the network to connect to and edit the settings
When done, click the network and wait for the connection.
It's done

– KUbuntu

Open the main "(Applications/)Internet" menu and select "KNetworkmanager" + password.
Wait a little (30 seconds ?)
Click the KNetworkManager icon, activate the wifi interface, select your Wifi network and set the WEP key if and as needed.
Wait a little (30 seconds again ?) and try to surf... It should be OK.

Conclusion

I confess I'm a quite new linux user. This notice is certainly not complete nor professionnal but I'm happy to give this to the Linux community. At this point, I don't use KUbuntu anymore because Ubuntu is a bit lighter and I've no more Wifi connection problems. I will probably soon try a Gentoo distro on the KUbuntu partition :-)

Don't hesitate to ask for further details about this laptop and sorry for my (bad ?) english ;-)

Installing Ubuntu 6.06 LTS (64 bits PC) on a HP Pavilion DV5137EU

François Rygaert (aka Suske) — 2006-10-27T17:34:29Z

Installing Ubuntu Dapper was as easy as clicking on "Next" a few times BUT, if you want to keep a dual boot with XPhoome, DON'T LET UBUNTU installer make the partitionning as he would reformat the full harddisk.
The wired ethernet connection was perfectly detected, so upgrades and turn arounds were quite easy too (I'm networking with a router including DHCP server). I have had a bit more difficulties to have the integrated wifi chipset working in an efficient way. But it is OK now.

Partitionning the hard drive

1. If you wan to have a full Linux laptop
Nothing special to say: I call it the "Next, next, next" installation process ((Perhaps "OK", i don't remember :-) ). You also will have to set a few informations of course (user name, and so on). It takes about 20 minues and no trace of another OS will remain. Go to next main title.

2. If you want to keep a wildows OS on the computer

You'll have to take the partionning of the machine in your hands. HP pre-installed one small "restore" primary partition (dev/hda2) at the end of the disk and one 35 Gbytes primary system partition at the beginning of the disk (dev/hda1).

In the remaining space, I decided to make
– a partition of 1 Gbytes for the swap,
– a partition of 10 Gbytes for the Ubuntu system,
– a partition of 20 Gbytes for the /home mount point,
– a partition of 10 Gbytes for testing other distributions, just in case ;-)

As you only can have 4 primary partitions, just decide to set it all in an extended one or to put the Ubuntu system in a primary and the rest in the extended or... If you don't want to have the /home in a specific partition, you just can create two primary partitions for the swap and the system with the /home included...
I decided:
– 10 Gb primary partition for Ubuntu ( "/" mount point)
– 30 Gb extended partition, in wich

1 GB for the /swap
20 Gb for the /home mount point
10 Gb left free in case... for testing another distribution, you never know ;-)

Then, I began the next, next, next install...

Having the integrated wifi card to work

Problem solved for me thanks to davidB21 on the french Ubuntu forum

Mainly, you'll have to :
– install the bcm43xx-fwcutter firmware extractor : use synaptic
– download the wl_apsta.o firmware to /home/your_name
– In a terminal, run the command
sudo bcm43xx-fwcutter -w /lib/firmware wl_apsta.o
– restart the computer (logoff, login is perhaps enough or even network restart - I don't know: I use to restart the computer, don't you know why ? Tips are welcome...)

Then, you'll have an integrated Wifi card but the default network icon seems not been working with it. You'll have to correct the file "/etc/network/interface", as the presence of 2 networks devices seems to disturb the things... Thus:

– deactivate the network using the control panel icon.
– open a terminal an execute gksudo edit /etc/network/interfaces. Replace the datas by

auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet dhcp

Save and close.)
– Open the "Applications/Internet" menu and select "Networkmanager" + password.
– Wait a little (30 seconds ?)
– Click the NetworkManager icon, activate the wifi interface, select your Wifi network and set the WEP key if and as needed.
– Wait a little (30 seconds again ?) and try to surf... It should be OK.

This should give you a 11Mbits wifi connection (max supported by the open source driver). Changing the network context could create the need to repeat these operations... Let know your experience !

/tmp/ Conclusion

This notice is certainly not complete nor professionnal. I confess I'm a quite new linux user. However, I'm happy to give this little contribution to the Linux community and I will probably come here back for further details about the wifi and the rest of this laptop (related to the firewire port and DV camcorder, for instance)...

Don't hesitate to leave your comments and sorry for my (bad ?) english ;-)
