I relativamente nuovi tipi di documenti Ufficio 2007 ha dato alcuni problemi di host web quando i loro clienti vogliono offrire i documenti per il download. Il più delle volte, i documenti vengono offerti dal server web come “text / html” che viene poi reso come una tonnellata di spazzatura sullo schermo dell'utente web.

Il modo migliore per risolvere il problema è quello di aggiungere tutte le MIME tipi di configurazione principale del server. IIS7 per Windows ha già questi tipi MIME impostati correttamente per default. IIS6 e IIS5 richiedono i tipi MIME da aggiungere, come potrebbe Apache su vecchi impianti. Per Apache, vi è anche una soluzione per il proprietario del dominio individuale per aggiungere i tipi MIME tramite Apache .htaccess File.

IIS 6 MIME tipo di aggiunta (per l'Amministratore del server)

Prima che questo può essere fatto, assicurarsi che il server sia impostato anche per consentire la modifica diretta della metabase:

  1. Carico Gestione IIS: Inizio -> RONU, “inetmgr” -> [Bene]
  2. Fare clic destro il “server” e fare clic su “Properties”
  3. All'interno “Internet Information Services” linguetta (di solito l'unica scheda), assicurare che la “Engrado modifiche dirette della metabase” casella è selezionata.
  4. Fare clic [Bene]

Assicurarsi di eseguire il backup della configurazione di IIS (qui per IIS5) in anticipo. Non prenderò alcuna responsabilità per un amministratore rompersi il server di. Ho ragione di credere che questo può lavorare anche su IIS5 però ho tanto motivo di credere che potrebbe solo dare un sacco di errori. Se un IIS5 / Finestre 2000 admin è disposto a provare questo per me dopo il backup la configurazione per favore fatemelo sapere dei risultati.

Copiare il testo riportato di seguito in un file denominato msoff07-addmime.vbs ed eseguirlo una volta dalla riga di comando digitando cscript msoff07-addmime.vbs e premendo Invio. Se si esegue più di una volta, i tipi MIME saranno aggiunti ogni tempo e avrete più voci identiche:

'Questo script aggiunge l'Ufficio necessaria 2007 Tipi MIME per un IIS 6 Server.
'Per utilizzare questo script, basta fare doppio-clic o eseguirlo dalla riga di comando.

Apache MIME tipo di aggiunta (per l'Amministratore del server)

Apache memorizza i suoi tipi MIME in un file normalmente si trova in $InstallPath / conf / mime.types. Vedere il mod_mime documentazione per maggiori informazioni su come funziona. Arch Linux installa i suoi tipi MIME in /etc / httpd / conf / mime.types e Parallels Plesk lo installa in /usr / / psa / admin / conf / mime.types locali. La vostra distribuzione potrebbe avere in un altro luogo, in modo da trovare la vostra mime.types file eseguendo individuare mime.types.

Aggiungere le seguenti righe al file mime.types:

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

Apparentemente, what operating system you use can say a lot about you. If you’re using some form of *nix, che 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 attitudine 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 e Debian bene. 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) non sarà, 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, tuttavia, they’re not going to be so lucky unless they like using “beta” 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” o “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, per esempio, 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. For this reason, 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!

Circa 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 bash copione, 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 a 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 (per esempio, the latest 3D graphics drivers):

OS: minmax (median)

Windows Vista: 15 – 30 (20) minutes

Ubuntu: 15 – 40 (20) minutes

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. Per esempio: If KDE 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. Instead, Arch Linux caught his eye. Arch Linux is a rolling-release (like Gentoo), binary-based (like Ubuntu) distribution. Its packages (bene, 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 pacuomo, has built-in dependency and conflict handling. I use another package manager, yogurt (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, o Arch User Repository. 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.

Anche, the AUR supports a voting system whereby popular packages get placed into the more official [community] deposito. 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 minutes. I don’t recommend Archlinux for newbies though I fare 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 su 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 *
bash: CD: /home/user/.Trash: No such file or directory
bash: sud: command not found
[user@user-desktop ~]$

The command CD ~/.Trash changes the directory (o present working directory) to the /home/user/.Trash folder. In questo caso, this folder doesn’t exist and so the pwd stays as /home/user/, the folder where tutto the user’s files and settings are saved.

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

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