J'ai l'inux nom de code Canterbury
by chris21.roux＠free.fr 27 Sep '13

27 Sep '13

Le projet "J'ai l'inux" vise Ã proposer une distribution Linux capable de filter les contenus notamment pornographiques, pour une utilisation Ã l'Ã©cole. Pour filtrer les contenus, il est nÃ©cessaire d'intervenir Ã l'intÃ©rieur du systÃ¨me pour intercepter les contenus Ã filtrer (on ne peut pas intervenir au niveau des trames rÃ©seau car Ã ce niveau les contenus ne sont pas interpÃ©tables). J'ai pensÃ© Ã utiliser des machines virtuelles pour dÃ©lÃ©guer Ã chaque machine virtuelle une portion spÃ©cifique du systÃ¨me Ã assurer. Cette idÃ©e est nÃ©e d'un poisson d'avril (April's fool joke) qui annonÃ§ait le projet Canterbury, visant Ã rÃ©unir le meilleur de 5 distributions Linux dans une nouvelle distribution. En tant que chrÃ©tien, je suis trÃ¨s sensible aux poissons d'avril qui ont pour objectif de se moquer des chrÃ©tiens. J'ai donc choisi ces 5 distributions et j'ai fait un prototype de test 64 bits: - Archlinux pour l'interface homme-machine et la virtualisation - Gentoo pour la compilation - Grml pour les entrÃ©es-sorties - Open-Suse pour les applications - Debian pour les applications 32 bits et la modÃ©lisation L'idÃ©e sous-jacente Ã ce projet, c'est un module noyau Ã dÃ©velopper qui permettra de router les appels systÃ¨me vers chaque distribution en fonction du type d'appel systÃ¨me et du rÃ´le de chaque distribution dans le systÃ¨me. Le pattern MVCA (ModÃ¨le= donnÃ©es, Vue=ihm, Controleur=noyau, Action=application) est utilisÃ© entre Archlinux, Grml et OpenSuse. Le filtrage de contenu s'effectue entre les applications et les vues grÃ¢ce au module noyau qui intercepte les donnÃ©es Ã filtrer et les dirige vers un filtreur hors noyau. Le filtreur applique des outils sur les donnÃ©es pour dÃ©cider si elles seront autorisÃ©es ou non. Pour dÃ©velopper le filtreur, un nouveau langage, Pmal, est Ã crÃ©er. On a besoin d'un nouveau langage qui doit Ãªtre capable de faire Ã©voluer ses programmes sans avoir Ã les interrompre. Ce langage sera basÃ© sur du typage fort, pour assurer la sÃ©curitÃ© du systÃ¨me. J'ai imaginÃ© un langage de glue pour faire Ã§a. Il s'agit d'un langage qui fait un usage important de la rÃ©flexivitÃ©: il connait ses constituants et peut agir dessus. Il est basÃ© sur le principe des conteneurs lÃ©gers: les classes composantes sont assemblÃ©es par inversion de controle. Chaque composante ne connait pas avec quel composant il sera reliÃ© dans les conteneurs lÃ©gers. Exemple: un objet A est reliÃ© Ã un objet de type D sur lequel il invoque une mÃ©thode b pour imprimer. A ne sait pas de quelle classe est l'objet de typez D. De D, 2 classes hÃ©ritent: B et C, pour 2 imprimantes diffÃ©rentes. Chaque classe B et C possÃ¨de un objet MÃ©thode implÃ©mentant la mÃ©thode b. Cet objet MÃ©thode porte des attributs "tags" qui le dÃ©crivent. Par exemple B a un tag "600dpi" et C a un tag "300dpi". Lorsque A demande a exÃ©cuter b, b est interceptÃ© par le conteneur lÃ©ger qui va filter les candidats possibles en fonction des tags. Finalement, le conteneur lÃ©ger choisira B pour optimiser la qualitÃ© d'impression, sans que A se soit jamais doutÃ© de rien. On pourra aussi avoir un objet proxy qui intercepte les requÃªtes b et les envoie de maniÃ¨re asynchrone. Ou encore, un compteur d'appels de mÃ©thode incrÃ©mental pour dÃ©tecter les boucles infinies et les rÃ©soudre en analysant le code invoquÃ© et en proposant une approximation si elles tendent vers une limite. Par exemple on pourra rÃ©soudre le paradoxe de ZÃ©non: Achille et la tortue font une course : Achille va 2 fois plus vite que la tortue. Chaque fois que Achille parcours la distance qui le sÃ©pare de la tortue, celle-ci parcours la moitiÃ© de cette distance. Ainsi une nouvelle distance plus petite les sÃ©pare... La rÃ©cursion est infinie. Si on compte les appels rÃ©cursifs avec une interruption par exemple au bout de 10 itÃ©rations, en analysant le code on peut dÃ©duire que la limite tend vers 0 et retourner cette rÃ©ponse comme approximation et mettre fin Ã la boucle. Si il n'y a pas de limite on interrompra aussi la boucle pour Ã©viter un engorgement systÃ¨me. Avec le niveau d'abstraction oÃ¹ une mÃ©thode est un objet on pour attacher cette mÃ©thode Ã un seul objet sans l'attacher Ã tous les objets de sa classe, Ã des fins de tests. Une fois testÃ©e, cette mÃ©thode pourra Ãªtre gÃ©nÃ©ralisÃ©e Ã toute la classe. A ce moment, la mÃ©thode sera interceptÃ©e par un proxy, puis mise en place, puis activÃ©e en dÃ©bloquant le proxy, permettant ainsi une Ã©volution du code et des classes du programme sans interruption. De plus, bien que fortement typÃ©, ce langage pourra Ãªtre exÃ©cutÃ© par du javascript, du fait de son niveau d'abstraction : les objets, les classes, les attributs et les mÃ©thodes sont tous des objets manipulables. Actuellement, je dispose d'un prototype faisant fonctionner les 5 distributions ensemble. J'ai presque terminÃ© le compilateur pour les mÃ©thodes du langage en Java 1.5. Il faut dÃ©velopper l'ensemble du langage Pmal, le module du noyau pour router les appels systÃ¨me et aussi un gestionnaire de paquets pour l'ensemble du systÃ¨me avec les 5 distributions. Il s'agit d'un travail Ã©norme, mais le proverbe dit: "La foi dÃ©place des montagnes". Contactez-moi si vous dÃ©sirez participer: chris21.roux(a)free.fr subject "J'ai l'inux".

sucessfull grml 2013.09-rc1 keyboard pt-br abnt / abnt2
by gilberto dos santos alves 16 Sep '13

16 Sep '13

I made tests using grml 2013.09-rc1 32bits and 64bits versions using boot options for work with brazilian portuguese keyboard layouts abnt and abnt2. at grml boot press (key tab) and add following options: xkeyboard=br lang=br tz=America/Sao_Paulo After this quick boot if you choose q (you go to terminal session with correct keyboard layout for computers sold here in Brazil that use abnt/abnt2 layout. If you choose x (for graphics options) xkeyboard brings rigth keyboard map for work with iceweasel (firefox) browser, (like chars /, :, ", '). And about not less import time zone tz=America/Sao_Paulo or tz=America/Brasilia (all very important for disk, file timestamps not in utc time but in brazil localtime utc -3). thanks. -- gilberto dos santos alves +55.11.98646-5049 sao paulo - sp - brasil

Need to unmap an alias in /etc/zsh/zshrc without modifying that file
by John 07 Sep '13

07 Sep '13

I'm using the grml-zsh-config package for Arch Linux. It places /etc/zsh/zshrc from grml upstream which contains an offending line: alias j='jobs -l' The strategy as I understand it is NOT to modify /etc/zsh/zshrc but rather to modify ~/.zshrc.local which I do have. My question is how can I unmap that alias in my ~/.zshrc.local leaving /etc/zsh/zshrc untouched? Btw, there is a great piece of software called autojump that works when users invoke the 'j' key which is why I want to unmap this. Thank you.

Remastering GRML for blind users
by Tony Sales 22 Jul '13

22 Jul '13

I have figured out how to remaster the GRML live cd so that it speaks automatically on boot :) Assuming you already know how to boot the live CD and mount a USB pendrive: Type: mkdir /tmp/cd && mkdir /tmp/cd/scripts Type: cd /tmp/cd/scripts Type: nano grml.sh Enter: #!/bin/bash modprobe speakup_soft espeakup loadkeys uk # optional exit 0 Press: Ctrl + x, then y to save and close script Type: chmod 777 grml.sh Type: cd Type: grml2iso -b scripts -c /tmp/cd -o grml_vi.iso /lib/live/mount/medium # wait for this to finish Then copy the iso to usb drive and burn to cd :) drbongo This message is private and confidential.

scripts boot option
by Tony Sales 19 Jul '13

19 Jul '13

Not clear about what the following line means: scripts => run script DCSDIR/scripts/grml.sh - does this mean that the /scripts/grml.sh must be in the root directory of the cd iso or usb flashdrive - not clear from the documentation where the DCSDIR is by default???

grml2usb
by Tony Sales 12 Jul '13

12 Jul '13

Hi, I want to make a custom version of grml for some blind students I am teaching programming to - I only want to make speakup active by default (commands: modprobe speakup_soft, espeakup) and change the default keyboard layout to en_uk (command: loadkeys uk). I had considered using grml-live but a flash drive install might do the trick so it possible to do this using a single line grml2usb command by adding these as boot options? If so what would the specific options be? drbongo This message is private and confidential. If you have received this message in error, please notify us and remove it from your system.

grml-live question
by Tony Sales 12 Jul '13

Hi, I want to make a custom version of grml for some blind students I am teaching programming to - I only want to make speakup active by default (commands: modprobe speakup_soft, espeakup), change the default keyboard layout to en_uk (command: loadkeys uk) and add a few example scripts. Is it possible to do this in a single line grml-live command? If not which config files would I have to add the commands to in order to make these relatively simple changes. drbongo This message is private and confidential.

Facing issues in setting up persistency. Using the grml-rescueboot option
by Sawbones Surio 18 Mai '13

18 Mai '13

Hello, This is my third attempt at getting grml to run persistently. Previous attempts used grml2usb to install it in tandem with other OSs, first using the grub, and subsequently syslinux. Both attempts ended badly. So, the third time, it was decided to opt for the option, grml-rescueboot to get things going. 0. Get a working Linux Mint system (extended partition sdX5). fdisk -l output is provided below. 1. Copied the grml64.iso into /boot/grml 2. Set up a separate partition called grml-home ( ---"--"--- sdX10) for persistence. 3. Created persistence.conf in the / of grml-home and added all the paths as prescribed in the wiki. 4. Having already installed the grml-rescueboot package, running update-grub added the iso into the menu. 5. Reboot, and choose grml64.iso 6. In the subsequent menu, chose the persistence option 7. Was provided with the following (approximately): > BOOT_IMAGE=/boot/grml64full/vmlinuz apm=power-off boot=live > live-media-path=/live/grml64-full/ bootid=grml64full201302 nomce > findiso=/boot/grml/grml64-full_2013.02.iso "${loopback}" "$kernelopts" > persistence > 8. After persistence, appended the following: persistence-label=grml-home 9. Continue boot. During the boot, the messages scroll too quickly to make out if the persistence system is mounted or not. 10. mount on the command line gives: > grml@grml ~ % mount > tmpfs on /run type tmpfs > (rw,noexec,nosuid,size=10%,mode=755,size=10%,mode=755) > tmpfs on /run/lock type tmpfs > (rw,noexec,nosuid,nodev,size=5242880,mode=1777,size=5242880,mode=1777) > proc on /proc type proc (rw,noexec,nosuid,nodev) > sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) > udev on /dev type tmpfs (rw,mode=0755) > rootfs on / type rootfs (rw) > /dev/loop0 on /lib/live/mount/medium type iso9660 (ro,noatime) > /dev/loop1 on /lib/live/mount/rootfs/grml64-full.squashfs type squashfs > (ro,noatime) > tmpfs on /lib/live/mount/overlay type tmpfs (rw,noatime,mode=755) > rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) > configfs on /sys/kernel/config type configfs (rw) > fusectl on /sys/fs/fuse/connections type fusectl (rw) > grml@grml ~ % > So, grml-home is not mounted or being used at all. And cat /proc/cmdline gives: > BOOT_IMAGE=/boot/grml64full/vmlinuz apm=power-off boot=live > live-media-path=/live/grml64-full/ bootid=grml64full201302 nomce > findiso=/boot/grml/grml64-full_2013.02.iso " " persistence > persistence-label=grml-home > Basically, no persistence partition was mounted. Despite the label added as a boot time. :-/ I would also like to bring your attention to the empty quotes in the above cmdline screen output. Last but not the least, here is the output of fdisk, to let you know my disk configuration: > grml@grml ~ % fdisk -l > > Disk /dev/sdb: 60.0 GB, 60011642880 bytes > 64 heads, 32 sectors/track, 57231 cylinders, total 117210240 sectors > Units = sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes > Disk identifier: 0x000a9f2a > > Device Boot Start End Blocks Id System > /dev/sdb1 * 2048 200703 99328 83 Linux > /dev/sdb2 200704 6492159 3145728 82 Linux swap / > Solaris > /dev/sdb3 6492160 48435199 20971520 83 Linux > /dev/sdb4 48435200 117209087 34386944 5 Extended > /dev/sdb5 48437248 69408767 10485760 83 Linux ## Linux > Mint > /dev/sdb6 69410816 86188031 8388608 83 Linux > /dev/sdb7 86190080 92049407 2929664 83 Linux > /dev/sdb8 92051456 95956991 1952768 83 Linux > /dev/sdb9 95959040 97535999 788480 83 Linux # contains > failed grml2usb --grub install > /dev/sdb10 97538048 98887679 674816 83 Linux ## grml-home > /dev/sdb11 98889728 101818367 1464320 83 Linux > /dev/sdb12 101820416 109631487 3905536 83 Linux > /dev/sdb13 109633536 117209087 3787776 83 Linux > > Disk /dev/sdc: 4089 MB, 4089446400 bytes > 61 heads, 60 sectors/track, 2182 cylinders, total 7987200 sectors > Units = sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes > Disk identifier: 0x00000000 > > Device Boot Start End Blocks Id System > /dev/sdc1 8192 7987199 3989504 7 HPFS/NTFS/exFAT > grml@grml ~ % > So, my questions, a) is there something extra that needs doing? b) why is persistence.conf or persistence-label not being picked up and honoured ? b) why those spaces in quotes in the commandline in the final output? d) .................................. ? I would greatly appreciate any insight from your end that I might be missing here. I would like to get this thing going forward, and recognising the grml-home partition and storing all my settings for the next session would be just fantastic. Many thanks in advance. Surio.
