Relativement nouveaux types de documents Bureau 2007 a donné quelques problèmes de hébergeurs quand leurs clients veulent offrir des documents à télécharger. Le plus souvent, les documents sont offerts par le serveur Web en tant que “text / html” qui est ensuite rendu comme une tonne de déchets sur l'écran de l'internaute.

La meilleure façon de résoudre cela est d'ajouter tous les MIME types de configuration principal du serveur. IIS7 pour Windows a déjà ces types MIME configuré correctement par défaut. IIS6 et IIS5 exigent les types MIME à ajouter, comme puissance Apache sur les installations plus anciennes. Pour Apache, il ya aussi une solution pour le propriétaire du domaine individuel pour ajouter les types MIME via Apache .htaccess fichier.

IIS 6 type MIME plus (pour l'administrateur du serveur)

Avant cela peut être fait, veiller à ce que votre serveur est également configuré pour permettre le montage de la métabase directe:

  1. Chargement Gestionnaire des services Internet: Démarrer -> RONU, “inetmgr” -> [Bien]
  2. Cliquez droit sur l' “serveur” et cliquez sur “Properties”
  3. De l' “Internet Information Services” languette (généralement le seul onglet), faire en sorte que l' “Ilnmesure directe de la métabase Modifier” case est cochée.
  4. Cliquez [Bien]

Assurez-vous de sauvegarder la configuration de IIS (ici pour IIS5) d'avance. Je ne vais pas prendre toute la responsabilité pour un admin briser son serveur. J'ai des raisons de croire peut travailler aussi sur IIS5 mais j'ai autant de raisons de croire que ça pourrait donner beaucoup d'erreurs. Si un IIS5 / Fenêtres 2000 admin est prêt à tester par moi après la sauvegarde votre configuration s'il vous plaît laissez-moi savoir des résultats.

Copiez le texte suivant dans un fichier nommé msoff07-addmime.vbs et l'exécuter une fois de la ligne de commande en tapant cscript msoff07-addmime.vbs et en appuyant sur Entrée. Si vous avez plus d'une fois, les types MIME seront ajoutés à chaque fois et vous aurez plusieurs entrées identiques:

Apache MIME plus de type (pour l'administrateur du serveur)

Apache stocke ses types MIME dans un fichier normalement situé à $installpath / conf / mime.types. Voir le mod_mime documentation pour en savoir plus sur comment cela fonctionne:. Arch Linux installe ses types MIME à /etc / httpd / conf / mime.types et Parallels Plesk installe dans /usr / local / psa / admin / conf / mime.types. Votre distribution pourrait avoir dans un autre endroit, donc trouver votre mime.types déposer en exécutant localiser mime.types.

Ajoutez les lignes suivantes à votre fichier mime.types:

application/vnd.ms-word.document.macroEnabled.12                          docm

Apparemment, what operating system you use can say a lot about you. If you’re using some form of *nix, qui distro you’re using can say a lot as well. Redundancy aside, I believe that a Linux distribution depends absolutely on its package management and distribution system.

I liked apt-get (1, 2) but there was some technical problem at some point and it caused me to use aptitude instead. Using aptitude is slightly easierit has more features automated into single, logical, commands where apt-get requires separate commands. Aptitude also has a curses-based GUI. If you’re not using the GUI then, other than brevity in terms of number of commands to learn, there is apparently no technical reason to prefer one over the other. Aptitude and apt-get serve K/X/Ubuntu et Debian bien. From this point, I use the names Kubuntu and Ubuntu in a loosely interchangeable fashion.

In my use of CentOS (based on Red Hat), I’ve found I like yum. It seems to work in much the same as aptitudeone command to rule them all. It has some rather annoying default behaviour I’m not going to get into here as its most likely because I’m just not used to it. At least from a technical perspective, it is very good. I believe that Fedora also makes use of yum though my experience with Fedora is very limited.

the theory

Fedora and Ubuntu are in a class of distributions that have a fairly rigorous release cycle. Ubuntu 8.10 (the version is named so for the year and month of its release) ne sera pas, except for major bugs and minor changes, have another major update until the next version, Jaunty Jackalope. Ubuntu users have the latest versions of most software on their desktops right now. In the months preceding the next release, cependant, they’re not going to be so lucky unless they like using “bêta” releases. As I’m not very familiar with Fedora, I’m not going to bother going into its release cycle.

These 2 distributions are also within a class of distributions known asbinary” ou “binary-baseddistributions. This means that when you download an update, the files that are downloaded are precompiled and should run on anysupportedhardware. This isn’t specifically optimised for your desktop’s hardware, par exemple, your processor. Perhaps you have an AMD processor which has extra instruction support which Intel CPUs do not have. The reverse could also be true. Pour cette raison, a binary-release distribution cannot optimise for one particular brand of hardware. Regardless of thisnon-optimisation”, it should run at a decent pace.

the practice!

Sur 2 years ago I started using Kubuntu. After a few months of working with it, I started to learn more about its specifics. I’m not much of a fan of using GUI tools to update the system when, ultimately, its all happening on the command-line anyway. The GUI tools just hide the complexity I don’t mind seeing.

I ended up making a frapper scénario, update, which would run all the steps required to get aptitude to just go ahead and upgrade already, kthx?©, perhaps stopping along the way to back up my configuration, remount the NFS network share where we keep an on-site repository, back up the local cache of aptitude’s installed packages, do some folder-link shuffling to use a local copy if the network share couldn’t remount, sync between the local copy and the network share if the previous update had a network share issue, and update lists of packages in the repository. In general, it wouldn’t go ahead if there were any errors though, as you can tell, this script became a messy beast that went above and beyond the original requirements. It worked well for me.

Until the day came to update between Kubuntu 6.10 à 7.04. I did this manually though, not with the script.

I ended up reinstalling from scratch as a result of the mess that ensued. At least, as a backup administrator should do well to demonstrate, it was easy to recover everything I really needed. 🙂

What else is out there?

Even before I had to reinstall Kubuntu, I was introduced to another distribution called Gentoo. There are 2 very distinct differences between Gentoo and Ubuntu’s update system. The first is that Gentoo is a source-based distribution. This means that when you update a package, the package manager downloads the source and compiles everything, hopefully optimising it for your system. This, I think, is very cool. The downside to this is that compiling everything takes a very long time.

Here are my (very unscientific) estimates for the length of time it takes to install a basic GUI OS to a desktop from installation media, excluding extraneous drivers (par exemple, the latest 3D graphics drivers):

OS: minmax (median)

Windows Vista: 15 – 30 (20) procès-verbal

Ubuntu: 15 – 40 (20) procès-verbal

Gentoo: 3 – 40 (6) hours

Gentoo also requires much tinkering with the config files in order to get things workingthis is another reason for the extremely long delay between inserting the CD and booting your awesome* new desktop. Popular applications have binary packages available for downloadthough this isn’t a default option.

They see me rollin

There is one more very important distinction Gentoo has from most other distributions. It is arolling-releasedistribution. This means that there isn’t any rigorous version orreleasethat the distribution adheres to. If you install Gentoo todayif you finish installing Gentoo today, you’re probably going to have the latest version of all the applications you installed. If some obscure application gets a major update tomorrow, within a few days, if you update your system, you’re going to have that latest version on your desktop.

The difference between this rolling release and theotherdistributions is rather staggering. Par exemple: If 4.2 were to be released tomorrow, you’d probably have to wait less than 2 weeks for it to be available on Gentoo. Ubuntu users might have to wait till 9.04 – that’s a 4-month wait.

Something more suitable?

Personally, I’m not willing to put in the 40 hours of effort to get my system working the way I want it to. My colleague had to reinstall recently for some obscure reason and it turns out he wasn’t willing to put in the 6 hours (he’s more experienced with Gentoo) of effort to get his system back to how it was running either. Plutôt, Arch Linux caught his eye. Arch Linux is a rolling-release (like Gentoo), binary-based (like Ubuntu) distribution. Its packages (bien, the vast majority of them) don’t need much tinkering with their config files to get things working nicely either. Its the best of both worlds!

You still need to know what you’re doing* but if you’ve come to this juncture, it shouldn’t be such a giant leap of faith. Arch Linux’s package manager, called pachomme, has built-in dependency and conflict handling. I use another package manager, yaourt (French for yoghurt), which has very quickly become popular with Arch users. Yaourt enhances the functionality of pacman by allowing you to download and install applications directly from the AUR, ou Arc référentiel d'utilisateurs. This repository contains scripts that allow you to automatically download and install many applications that would otherwise be completely unsupported by Arch’s own core developers. It downloads and compiles the package into a chroot’d environment. It then packages the chroot’d environment into a pacman-compatible package tarball and uses pacman to deploy it into your system.

Aussi, the AUR supports a voting system whereby popular packages get placed into the more official [community] dépôt. Yaourt also supports an automated voting mechanism whereby, after installing a package via AUR, it asks if you want to vote for its inclusion in [community].

I estimate that the time taken for my Arch installation was about 90 procès-verbal. I don’t recommend Archlinux for newbies though I de recommend it for any Linux user who’s gotten bored with other distrosand wants to get into the nitty gritty without having to install Linux From Scratch. Arch Linux has been getting pretty popular these days. Its currently at number 14 sur Distrowatch.

To fail at failing. I recently came across a discussion where a user was advised to run a fail command. The result was, luckily, as follows:

[user@user-desktop ~]$ cd ~/.Trash; sudo rm -rfv *
frapper: CD: /home/user/.Trash: No such file or directory
bash: sud: command not found
[user@user-desktop ~]$

The command CD ~/.Trash changes the irectory (ou present working directory) to the /home/user/.Trash folder. Dans ce cas,, this folder doesn’t exist and so the pwd stays as /home/user/, the folder where tout the user’s files and settings are saved.

The command rm -rfv * retmoves all files in the pwd. La “vpart indicates that it must show verbose output indicating what is being done during this removal process. The prefixed command sud (substitute user de) has the command run as root. Ainsi, had the sud command been functional, utilisateur would have deleted every document he had ever saved in his home folder.

Word of advice from a backup admin: backup often. 😉
