Vim | Templates

Posted by Dominique Derrier

En ce moment je fais quelques pages html, pour tenter de garder une ligne standard de format, je me suis dit qu'un template était la bonne solution.

Mais comment utiliser des template avec VI ?
... Rien de plus facile !
En Trois actes:

  • Créer un répertoire Template
  • Mapper les noms de fichiers avec les Templates
  • Rulez !

Un serveur svn over ssh

Posted by Dominique Derrier

Tout le monde connait le fabuleux gestionnaire de version subversion non ? svn.
> L'idée est d'utiliser le transfert de fichiers dans la repository via ssh cryptée.
> L'autre contrainte est de ne pas donner un shell aux utilisateurs de svn.

Ssh permet cela facilement: Go pour un Setup en 5min avec un serveur linux ?

Lancer des programmes sur un Windows distant depuis Linux

Posted by Dominique Derrier

Mon pot Johnny a trouvé un super soft pour lancer des programmes windows depuis Linux.

C'est une bonne astuce pour faire quelques tests.

========>
Il peut être très pratique de lancer depuis un serveur central Linux des commandes sur un serveur Windows distant.
Je pense notamment à des actions exécutées suite à une alerte de monitoring pour relancer un service Windows par exemple.
WinEXE est un utilitaire en ligne de commande, permettant de lancer des commandes sur un serveur Windows distant depuis une machine Linux.

Port Serie Saison I

Posted by Dominique Derrier

db9_pinoutsEt ben, voila j'ai perdu un écran sur la machine qui me sert de routeur. Sans clavier ni écran le diagnostique n'est pas facile en cas d'erreur. Mais heureusement le mode console est là. Je ne sais pas depuis combien de temps cela existe dans le kernel, mais je pense que cela ne doit pas être loin des origines.

Générateur de Fla$h Swftools

Posted by Dominique Derrier

Dans la série je ne sais pas quoi faire le jour de nöel, j'ai testé pour vous swftools.
C'est un outil GPL (opensource) qui permet de faire des fichiers flash en décrivant chaque Keyframe, le logiciel permet de compiler le fichier et de générer l'animation Flash.

Bref c'est un petit utilitaire en mode texte qui peut faire quelques animations sympathiques pour vos cartes de voeux... et donner un peu de vie à un message en  mode texte.
Bonne Année 2010 à tous.

Whitehouse.gov is now powered by Drupal, an Open Source Software.

Interestingly, the Department of Defense of the USA has released a memo where it is said that "it is required to conduct market research... [and] include OSS [in the research] when it may meet mission needs."

It's official. World Domination is coming.

FreeBSD8.0rc1 “run_interrupt_driven_hooks”

Posted by Selven

As soon as FreeBSD8.0rc1 came out (some hours after being uploaded) i wanted to try it out on my new work laptop (HP DV6 1160ei), surprised and sad i was to find that the installer itself couldn't proceed further...i got bumped with this error:

lots of stuffs after the bootloader....
:
:
:
uhub7: 8 ports with 8 removable, self powered
ugen7.2: at usbus7
ugen4.2: at usbus4
ugen5.2: at usbus5
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config

run_interrupt_driven_hooks: still waiting after 240 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 300 seconds for xpt_config

stalls here and freezes forever. Which means your installation cannot proceed further.

Seems the problem is related to the firewire support, this problem has been here since FreeBSD7.2,
it seems to affect mostly gigabyte and asus mainboards (others plz do comfirm??). Seems the systems tries to query for firewire storage devices and then is stucked at that point..

The easy fix to this is to just go into your BIOS and disable firewire device and install your FreeBSD leisurely....

but but but... poor me, i just got a damned new HP Pavillon DV6 sexy lookin laptop which doesn't have any advanced BIOS settings to disable firewire .
I definitely couldn't be vulgar and just open that up and take out the firewire port :p that would be gross... specially since the laptop isn't my property.

So my my my, i had to find a way out of this, googling around, it seems there's no fix for that, since most are lucky enough to have disable firewire in their bios itself,
unless i was crazy and maso to dare run winxp or win vista on my laptop [thoughts of which were so disturbing that i dared not use that laptop and was even thinking of returning it back.

since the install iso itself boots a freebsd kernel, i believed for a temporary solution i could disable firewire via device hints in that loader console,
unfortunately, it didn't seem to work
.... so i did what most people would have done since they have the source and the ability to do anything with it... i played with it :p

i found a solution :p remove firewire support in the iso :p.. all the ways i don't use that, if ever am gonna use that later on, once i've got freeBSD installed, i can think of it later and get it to work later on :p.

So... till i find the bug and correct it in the source itself or till someone else does it, i've managed to get the installer to work...

here's how:

Requirements:

  • Download the dvd iso image of FreeBSD 8.0 Rc1.
  • You need a FreeBSD8.0Rc1 installed somewhere [I installed one on a VM (since i didn't wanna break existing installation)]

(ps. it can be a minimal installation, since you don't need desktop or anything in this temporary setup, you just need it to recompile that kernel in the installation cd :p)
10 GB of space minimum

What to do?

  • log in as root (who cares its a vm machine and you are going to break it all the ways)
  • Extract the contents of the iso in a folder somewhere in a directory somewhere in your FreeBSD8.0rc1 [temporary installation] on the vm.

a vm with freebsd for the compilation

(since i had already burnt it on a dvd, i just copied the contents of the dvd in a folder called /usr/disk1)

  • use sysintall to install the release source and the kernel sources. (configure>distributions>src> sys and release).
  • configure your kernel so as you don't include firewire devices:
  • cd /usr/src/sys/i386/conf (change i386 to your architecture)
  • cp GENERIC SELVENKERNEL
  • nano SELVENKERNEL (or vi or ee or whatever editor you like) (comment out the firewire related modules [among the last lines)
  • make buildkernel KERNCONF=SELVENKERNEL
  • make installkernel KERNCONF=SELVENKERNEL

that's it, you have already completed most of the work, go to your /usr/disk1 directory [where the dvd iso contents were copied earlier remove the kernel folder in its boot directory and replaced with your new kernel). do like this:

  • rm -rf /usr/disk1/boot/kernel
  • cp -R /boot/kernel /usr/disk1/boot/kernel

great we are almost done... (ps. if you want you can set splash images also :p)

anywayz, you should then use mkisoimages to build your new dvd iso....

  • sh /usr/src/release/i386/mkisoimages.sh -b FreeBSD8 /isowork/myrelease.iso /usr/disk1

where -b FreeBSD8 can be anything you want, /isowork is just a directory i have made to keep the final iso, and /usr/disk1 is the contents which you want to have in your iso :p.

If ever it complains about some rr_moved error or something simmillar, please do delete the directory named rr_moved from your /usr/disk1 directory

  • rm -rf /usr/disk1/rr_moved

so relaunch your mkisoimages if ever it failed with the rr_moved :p.

after its done... you shall have a nice iso in your destination directory /isowork :p (or your directory you chose)

  • you can use cdrecord to burn the iso to a dvd :p

Though, being lazy, i just scp'ed it to my other computers, went to sleep, woke up in the morning and burnt it 🙂

:p I tried to launch the install from that DVD ... now it works! yupeee, finally i'll be able to use that laptop.

Hope this helped out those poor souls out their who wanted to have their Favourite OS on their HP Pavillon DV6 :p

EDIT: Additional stuffs, once installed your new system shall be unbootable, you should boot from the installation dvd, start a shell there, mount the partition and cp -R /mnt2/boot/kernel to your new /boot directory in your harddisk (after mounting it somewhere).

Also, if you are using gnome please add these in /etc/rc.conf

moused_enable="YES"
hald_enable="YES"
dbus_enable="YES"

ps. actually i wanted to try out 8.0 rc1 in the hope that i might catch a bug and hoped to find a fix and hopefully contribute back to the community.. lol .. that one was unexpected!

pps. plz ignore gramatical errors, typed this in nano, and refrain from starting OS flamewars since its tiring to reply to those :p

ppps. To save you the trouble i can upload the iso image, lemme know.

pppps. Am not responsible if you blow up your computer or whatever :p. My sincere apologies in case of errors.
