Hi,
Can somebody tell me how is created this device?
When I'm connecting my webcam, nothing happends but in messages.log:

And always no /dev/video0
I create it ("mknod /dev/video0 c 81 0; chmod go+wr /dev/video0"), verify

The kernel module is responsible for doing a bunch of things that eventually results in the creation of a device node.
If you don't get a device node, it usually means that your hardware device is not supported by the Linux kernel.

The device is automatically created if the driver recognize the device. If i do dmesg | grep gspca : gspca: no version for "struct_module" found: kernel tainted. /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: USB SPCA5XX camera found.(ZC3XX) /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: [spca5xx_probe:3885] Camera type JPEG /var/tmp/bach-build/BUILD/gspcav1-20060925/Vimicro/zc3xx.h: [zc3xx_config:515] Sensor ID:10 /var/tmp/bach-build/BUILD/gspcav1-20060925/Vimicro/zc3xx.h: [zc3xx_config:587] Find Sensor PAS106 /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: [spca5xx_getcapability:1163] maxw 352 maxh 288 minw 176 minh 144 usbcore: registered new driver gspca /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: gspca driver 01.00.04 registered
Perhaps also the device created is not /dev/vodeo0 but /dev/videoX. For me the device change at every reboot because i have also a tv card and the first one get /dev/video0, the second /dev/video1 and so on...
Hope this will help you.

Hmm - and does opening ekiga or kopete from a terminal not give any messages?

Did you start it from a terminal? That usually gives you messages while it is working.

You are going to have to run something to use with the webcam, and whatever you choose you will need to run some setup or config option, or how will it find your camera? When I had problems I did find that running the various video apps from a terminal brought me some clues.

Well, I don't know what "supported" means here. That page does not specify the kernel version what kernel version it uses as a reference. It also indicates that this hardware is supported by the "spca5xx" kernel driver.
I find no kernel module of that name on my FC 6 box. I took a quick grep through the kernel 2.6.18 source, and I find no evidence of the existence of this kernel module. Granted, this wasn't an exhaustive search, but I couldn't find anything.
Furthermore, if you actually bothered to click the "Download" link at the top of that page, you would've discovered that the driver for this hardware is not part of the Linux kernel, but is a separate kernel driver module that needs to be downloaded, and built. That is, normally, a rather delicate task, but you got lucky here. That page contains a broken link to an alleged prebuilt kernel module package for FC4. But, it's fairly easy to figure out that the contents of http://atrpms.net/dist/fc6/gspca/ look to be rather promising for you.
However, rather than randomly downloading some of these rpms, why don't you go to http://atrpms.net, and follow the instructions for adding the atrpms repository to yum, then you should be able to get everything going simply by running "yum install foo", with your only remaining hurdle is to figure out what "foo" should be.
Looks like, at the bare minimum, you should install the "gspcav1" rpm, and the correct "gspcav1-kmdl-<kver>" rpm, that exactly matches the kernel version you're running.

rpms kernel version matches.
I send a mail to the gspca maintener who told me that this module isn't for my cam and that I have to take the uvcvideo driver (http://linux-uvc.berlios.de/)
Unfortunaly, after successful compile and install, when I want to load it :

Looks like you compiled the kernel module against a version of the kernel that's different than the running kernel's version.
You need to be very careful when doing this, by hand. You're much better off searching for a pre-built rpm that does this for you.

Hi evrybody, I have 2 machines under FC5. I'm trying to configure NFS (Network File System) between these 2 machines (client=pc006, server=pc005). So, I have added this in /etc/fstab and in /etc/exports: /etc/fstab: #pc005:/home/rep-export /home/rep-import nfs defaults 0 0 192.168.1.5:/home/rep-export /home/rep-import nfs defaults 0 0
/etc/exports: /home/rep-export *(rw,no_root_squash)
==> When I use in the client the "IP address" of the server, it works very fine, but when I put the "name" of the server at the place of this IP address it generate this error: mount -a mount to NFS server "pc005" failled
There is no error is added to the /var/log/messages file. Apparently, the problem is that my PC does'nt recognize the name of the server (pc005). (but ping pc005 works fine!). I have added in /etc/hosts this line: 192.168.1.5 pc005 but the problem persists.
Do you know what must I do to resolve this problem.
Thnx. Lil

Thnx. Lil

You've mentioned adding to your hosts file, but have you tried adding both machine names to your hosts files, on both PCs?
I've not tried using machine names with numbers in them. I wonder if there's an issue related to that?

I believe that for the hostname to work it must resolve either by being in the hosts file or by DNS.
So the client would at least need the servers host name in /etc/hosts with proper IP mapping.

Hi,
I want to install MS-Word under my laptop by using "Wine", but I have encountered this error "unknown error". Do you have solutions to my problem, or an other suggestion?
Best bet is to use Crossover Office over Wine, though you'll get hit by that annoying Genuine Software crap thing which means you can't get any updates or fixes.
Me, I'd use OpenOffice - way much more reliable!

Two real options if you don't want to pay:
1> Use OpenOffice instead. There's a reason MS Office won't run under Linux very well - it wasn't designed for it. I wouldn't hold your breath waiting for Microsoft to make a "Microsoft Office for Linux".
2> Get a virtual machine emulator for Linux, and install Windows and Office under that.

Exactly my point. If you want to present a professional appearance, do not rely on the grammar-checking in MS Office to get you there. Nothing replaces checking with a Harbrace (or a native speaker) when you need to make sure that what you are sending is grammatically correct. A good idea is to contract with a local college student who speaks both languages to check your most important emails. The low-priority ones do not have to be perfect. But if you are trying to project a professional appearance, nothing beats having the language in your email (or letters) verified by a native speaker.

Very much so - especially as English is descriptive (That is there are no rules, the language is described by studing its usage).
Incidentally if you like grammar, pedantry and language then pulling the translation files for fedora tools (and Gnome, KDE etc) and checking them is a very useful non-programming way to improve free software. Many of the applications do not use good clear language.

I've never heard of it before, but just doing a Google search on it suggests that they're a publisher that publishes writing guides.

A Harbrace is short for the "Harbrace Handbook". It is a reference guide and textbook for student writers and teachers. Each chapter deals with a certain aspect of the English language and its correct usage. The chapters are labeled with a number (and within them each section with a letter) corresponding to what aspect it addresses. When you write a paper and the teacher grades it, they will mark the grammatical mistakes with the number and letter which points to where you can find the correct usage (many times I received papers back with lots of red markings on it).
There are other handbooks out there detailing proper English grammar but the Harbrace was one with which quite a few of us grew up. I think with the internationalization of business (brought on in large part by the Internet), most people understand that not everyone speaks English and the majority will give grammatical mistakes a pass when it is directly from a non-native speaker.

I think you have unreasonable expectations. Back when computers first started to be used to process things other than projectile trajectories, people thought we'd be using them in 20 yrs or so to do real language processing. That was in about 1950 or so. It hasn't ever happened, because the problem is extremely difficult. We perceive language processing to be easy, because we have unperceived hardware assist in our brains. Consider:
"Fruit flies like a banana."
Is "flies" a verb, or a noun?

I think that there is a grammer checker for OOo that you can install in development. Check the OOo mail list archive for more info or join the OOo mail list and ask there.
I used to use a grammer checker in WordPerfect and found that is was more of a pain and took more time than it was worth.

I don't agree. I don't really expect them to be able to do any better than they do. Human language is a rather complex thing, with some quite large regional variations. But computer programmers like to try and reduce things down to the lowest common denominator. The two are opposite goals.

Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
I have some experience in translating complex data, which is somewhat related to the issue of grammar checking. What occurs is event sequence and context related, along with the baggage that we humans carry, called memories. Thus two people conversing often have differing ideas about the topic, based upon their own experience and memories, which is then modified by the event sequence that lead to the statement/paragraph/topic under discussion. This in turn is further refined by the event sequence of the particular conversation and topic, queried and rectified by questions and answers or statements by the party(ies) involved. This also occurs in complex programs, where the programmer has prior experience (or art as some like to call it), along with personal coding styles, experience in fixing problems (or working around them) which is particular to the view of the program and the familiarity the programmer has with the hardware, software libraries and tools at his disposal. Thus if five different programmers are asked to create a table ot data encoded by color and location, you would get 5 different programs to accomplish that task. They could all be equivalent in input and output, but the internalization of the data, the procedures followed and the methods used to achieve that result would be different. Also the appearance of the initial result from each programmer would likely be different as well, in things like table representation, dividers, lines or no lines, labels or no lables etc. etc. Further it is unlikely that any of the outputs would match your exact expectations on the first pass.
Thus even though the topic was understood, the concepts clear and the desired output known, the output was somewhat non-deterministic. This is true of Grammar as well.
If, for instance one were to make a speach about Gettysburg in modern language, one might say: Eighty seven years ago, people established America to grant liberty and justice to everyone equally.
Does that say the same thing as: Hey man, my great grandpa started this country so I could say this stuff.
Or: Four score and seven years ago, our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal. Abrahm Lincoln.
Perhpas each has the same feeling to the speaker, and even is correct for the audience, yet the choice of words would be very hard to justify in a programming context without a lot of background information that simply is not part of the words being spoken. The historical context, the nature of the speaker, the nature and background of the audience, and the requirements of settling an issue divisive to the nation. A great task for a man, but one that cannot come (yet) within the capability of a computer.
Grammar checkers can do some interesting things, and they can improve clarity, but they do not make one accomplished in language. However, their value for a non-native speaker is considerable. I have an ex-wife who is Korean. It would have been wonderful to have had some better tools to help us in our relationship.
Expectations are simple. getting something to meet those expectations is much like correcting grammar, however, Tim, you can certainly add your skill and knowledge to those attempting this very difficult and challenging task. Dr. Kurzweil and others have been working on this for decades. Check out the history of Dragon systems.

To jump back into the thread; grammar checkers should not be relied upon by non-native speakers for important messages. As has been noted, they have questionable value when writing something which is being used to promote a professional image. If you are writing emails to a mailing list, then they are fine and incorrect language is usually excused. If you are writing to a business prospect, then there is no substitute for a native speaker checking over your work before sending it out. If our company does a presentation utilizing references to another language, I always hire one of the local college students who is from that area to double-check our work. Being American and dealing mostly with businesspeople who speak English, I do not have too much of a problem. But if I was in another country trying to woo an English-speaking company, you can be sure that relying on Microsoft to correct my correspondence is way too much of a gamble for me.

Hi, Patrick, There are several levels of communications, among them are publicity, professional promotion, professional intercourse, professional interaction, personal interaction, personal, urgent requests for assistance.
The order I have listed them is also IMHO the order of priority for context and grammar correctness, and should also be tied to cost/effect relationships. I believe that the use of grammar checkers satisfies from personal interaction thorugh urgent requests for assistance. From the personal level up, you have to make a tradeoff of the cost in time/money/effort/reward as you move upward in this chain, from using local and personal friends reviewing the work to hiring professional copywriters. And you are right that from professional interaction up, the grammar checker should not be relied on as the sole check of grammar and context. However as input to the professional checker, using a grammar checker to help clean up the content can be helpful. I used my rough input, one checked by either a grammar checker or a local friend to input my desires to a professional copy writer, and gave the professional copywriter both copies along with copious personal interaction in some cases.
Note that I did not say that the grammar checker should be the exclusive process, but only that it had great value. As to the level of communications, the very best communications is always written in sixth or eighth grade level grammar and context. This is common in the US. In some communications lowering this to fourth or fifth grade level will further ensure good comprehension by a larger audience. However when doing professional communications you should always employ language relative to the age and sophistication of the audience. And remember that communications is always two ways in person, simplex in letters and email, and unidirectional in presentations or advertising copy, thus lowering the bar on technical levels as you go into this last list of communications. These things make specifying grammar in the US difficult, but in some countries, such as Korea (one I am personally familiar with) there are also issues of gender, generational and professional status that are an important part of the communications forms of address and grammar selection.

There really isn't a difference between desktop and server in Fedora. It rather depends on what you install.
My question relates mainly these 2 points: 1) Security, 2) The capacity of the machine to answer several web requests.
If you don't install the desktop stuff (X, Gnome, KDE, etc.) and install the various server components, then you've got a server instead of a desktop. You could install everything, of course. If you change the initdefault line in /etc/inittab from:
id:5:initdefault:
to
id:3:initdefault:
then the system will boot up to command line mode (NOT GUI mode) and it'll behave like 90% of the servers out there, but you have the ability to go to full GUI mode when you want by doing:

then the system will boot up to command line mode (NOT GUI mode) and it'll behave like 90% of the servers out there, but you have the ability to go to full GUI mode when you want by doing:
telinit 5
as the root user.
Or as a normal user -
startx
Then you don't have to switch run levels - which you probably don't want to do on a server (except to switch to run level 1 for maintenance, but that usually done rarely and only in emergency - and often done by rebooting the machine into run level 1)
When you use startx - logging out of your desktop/window manager returns you to the cli.

I want to know if when we upgrade the desktop (client) version of some distribution (like fedora) to its server version is equivalent to install directly this server version? My question relates mainly these 2 points: 1) Security, 2) The capacity of the machine to answer several web requests.
Well, up to FC6 (current release), there isn't two different versions. Those choices just preselect what packages are installed by default. If you install the Apache webserver, you get the same Apache webserver, whether you're starting off with a desktop or server default set of packages. Likewise for other choices, you get the same things.
The choices just preselect what some people considered were good defaults for a server (file serving, web serving, mail, and whatever), versus what was probabaly good defaults for a desktop box (office software, mail clients, web browsers, etc.).
