Ethernet
how do we connect two computer using only an ethernet cable .both computer use win xp pro sp2.i need to transfer big files.--Utkarshkukreti 06:17, 16 October 2006 (UTC)

You will need a crossover ethernet cable. You can tell the difference between crossover and straight-through ethernet cabling by looking at the pinout at the ends of the cable. If you already have a cable, though, it is very likely a straight through cable, which won't work computer-to-computer. I've seen adapters before but it would probably make more sense to just get another cable and a switch which allows for network expandibility.


 * Aren't modern network cards able to automatically cross the wires if you are using the wrong kind of cable, or does that only go for switches and other such external boxes? —Bromskloss 08:37, 16 October 2006 (UTC)


 * Crossover_cable. I gather that it's most common in 1000BASE-T cards or better. Last time I attempted to do this it didn't work with a straight-through, but both cards were older 100 Mbit/s dealies. -- Consumed Crustacean (talk) 09:23, 16 October 2006 (UTC)

Javascript Ticker
Ow wise wikipedians! I need your wise advise. i want to make a javascript ticker like the one on []. I would like picture in it and would like for it to be really easy to update. Do you know any good sites? can you help me? Oh and i use dreamweaver...is this ny help to me for projraming the ticker?


 * Place the text area in a div and give it a unique name ("ticker" for example). use document.getElementById("ticker") to acess the object. for example document.getElementById("ticker").innerHTML="Javascript rules" will change the text of the ticker to "javascript rules".  Use a setTimeout function (or setInterval) to change the text every few seconds.  The site you showed also had a nice fading out affect.  I imagine that they change the color of the text a few times before they change the text (docment.getElementById("ticker").style.color=some lighter color).  The javascript has to change every time the page load so the server has to write the part of the javascript that contains the headlines.  This would probally be in an array of some sort.  If you didn't understand any of that pay someone else to write it.  Jon513 16:51, 16 October 2006 (UTC)


 * It doesn't necessarily have to be updated only on page load. News is like the perfect use of XML (and they probably have an RSS feed already so chances are XML files are already being built for each news story) so you just have to collabarate all the files together and use AJAX to download them in realtime! --⁪froth T C  20:02, 16 October 2006 (UTC)

New computer help
I'm kind of new at this so bear with me. I recently purchased parts so i can build my own gaming computer and ran into a little trouble. My motherboard (gigabyte k89f-9) does not have a DVI or VGA input. Now i never thought this would be an issue because my video card (7900gt) had the input. Until today that was, i realised that in order to use my PCI-E for monitor display i needed to configure it through the bios. Which i can't do because of the lack of VGA/DVI inputs.

I'm really confused and can't think of one possible way to fix this. Can someone please help with detailed instruction? : D Thanks in advance


 * You sound pretty screwed. Are you sure it has to be "configured" through the bios? What could there possibly be to configure? --⁪froth T C  19:58, 16 October 2006 (UTC)

Hey mate you sure you got the right model? I don't think gigabyte k89f-9 is real...which is why you can't get it working...lol...more info and i will help you.


 * Your confusion is caused by believing there is something wrong. The motherboard came with a manual. Read it. Now read it again. If you now know the difference between input and output go to step 1 Install processor and heatsink+fan on motherboard, attach fan power lead to mother board, step 2 install memory, step 3 install m/b in case, step 4 connect up all the correct powerleads making sure they are the right way round step 4 install video card. At this stage we should have a working computer - no boot device yet but if we were to connect a keyboard and monitor to their output ports then power up we would be able to enter the bios (Press DEL key for setup). Note that the video works! It may not be 1024x768 but it works nothing special required. Now we can power off, connect the cdrom (set as boot device in bios, but don't bother with the cd-in lead. I never use it. YMMV) and hd. Power up, insert OS cd, install and go. Once you have built one the rest are easy! Best of luck --87.74.59.28 12:52, 17 October 2006 (UTC)

Looking for forum host which offers Google Groups-like integration.
I have recently left Google Groups (I wrote the article) after someone forged e-mail headers and posted insulting messages to my group, and Google suspended my posting privileges, thinking I posted those messages. I have written to Google, but have not received a response.

I realised that the mailing list functionality of Google Groups is inherently insecure, and am looking for another website to host my group/forum. Nevertheless, I am attracted to the integration features of Google Groups, and I hope to find a new host that has similar integration features without the inherent insecurity of mailing lists.

These are my criteria for a new forum host:


 * The forum must be hosted on their website, with URL http://forumname.forumhost.com or http://forumhost.com/forumname or something similar. I don't want to host a forum on my own domain; I don't have my own website.
 * The forum should not be a mailing list. It should not be possible to post messages to the forum through e-mail. Posting through e-mail is the "inherent security risk" I mentioned, as anyone can forge e-mail headers and post to the group under an established member's name.
 * The account I create with them should allow me to join/create multiple forums hosted on their website, unlike most forum hosts, where an account only grants me access to one forum. This will allow me to use the forum hosting website to meet like-minded people by joining/creating many forums based on my interests. They should have a searchable directory of forums for me to easily find those pertaining to my interests.
 * The forum host should be compatible with Opera.

Please recommend me a forum host that meets my requirements. The more sites you recommend, the better; I enjoy trying out new sites and choosing which one I like best.

Computing /IT
I have Microsoft windows xp / vista service pack 2,when i give command/cmd in the run from the START menu,the computer restarted every time when i give this commnds. Any one pls clear this problem. THANK YOU.


 * XP and Vista at the same time...? Is the command "shutdown -s"? ;) Benbread 18:42, 16 October 2006 (UTC)

Online reading list (del.icio.us for books)
Is there a web 2.0-style reading list website anywhere? I want to be able to add books that I want to read to the list, and perhaps tag them and compare them to what other people are reading. Basically, a del.icio.us or rememberthemilk for books. Looking around, I haven't been able to find anything like it. Anyone know anything like this? Thanks! --Mary


 * Actually, I've now found one. LibraryThing seems to be what I want. If anyone else has good suggestions, though, I'd love to hear them. --Mary

ARPANET
what "language" did ARPANET "speak" in? -- 64.12.116.130 17:52, 16 October 2006 (UTC)

permanent CPU usage in Quicklaunch bar
When I open up the Task Manager, the CPU usage icon will appear in my quick launch bar. Unfortunately, when I exit the Task Manager, it goes away too. Is there any way to keep that CPU usage icon in my quick launch bar for easy viewing? Hyenaste (tell) 19:10, 16 October 2006 (UTC)


 * (For WinXP) Open task manager, click the 'options' menu and check 'hide when minimised'. Then minimise task manager. It's sort of cheating, because task manager will still be running. CaptainVindaloo t c e 19:29, 16 October 2006 (UTC)


 * And it's crappily designed, taking up 5MB of memory and consuming 2% of my cpu cycles --⁪froth T C  19:56, 16 October 2006 (UTC)


 * Any solution to that issue, frothy? Hyenaste (tell) 19:51, 18 October 2006 (UTC)

windows preboot
Is there some list of programs that will be run in the next windows "preboot" (like the HKCU/Software/Microsoft/CurrentVersion/Run key for standard startup items)? By preboot I mean some kind of pre-windows-startup, not actually during the bootstrap process. If there's no centralized location then how do programs put themselves in preboot? Do they register themselves through some DLL? Ad-aware for example sometimes asks you to restart so that it can intervene before explorer starts to prevent malware from loading. Also I've seen a couple of products that supplement the windows login for security. How do they start before explorer? --⁪froth T C  19:53, 16 October 2006 (UTC)


 * I'm going to recommend the same program I always recommend when it comes to windows startup, sysinternals Autoruns. It will list every exe, dll, or whatever that launches when windows does. It doesn't add stuff to it, but it gives all the locations where stuff is started automatically. You should be able to figure out how to do it from there. Oskar 20:02, 16 October 2006 (UTC)


 * Have you tried typing msconfig into your run command? I think it has what you are looking for. Vespine 05:32, 19 October 2006 (UTC)

ipmi_si
I am trying to install Dell OpenManage under a  RedHat EL4 MP  with a kernel of 2.6.11., but the OpenIPMI modules fail to build. We try to Google around, but it took as nowhere. I run the script:

srvadmin/linux/supportscripts/srvadmin-install.sh

The following output displays the chosen installation steps:

Server Administrator Custom Install Utility Selected Options - All Dependencies - Server Administrator CLI - Server Administrator Web Server - Diagnostic Service - Storage Management - Remote Access Core - Remote Access SA Plugins Components for Server Administrator Managed Node Software: [x] 1. Server Administrator CLI [x] 2. Server Administrator Web Server [x] 3. Diagnostic Service [x] 4. Storage Management [x] 5. Remote Access Core [x] 6. Remote Access SA Plugins [x] 7. All Enter the number to select a component from the above list. Enter c to copy selected components to destination folder. Enter i to install the selected components. Enter r to reset selection and start over. Enter q to quit. Enter : i Default install location is: /opt/dell/srvadmin Do you want to change it? Press ('y' for yes | 'Enter' for default):

After pressing Enter, we obtain the following installation error:

However, a "sufficient" version of the OpenIPMI driver RPM is currently installed on the system. The OpenIPMI driver modules for the running kernel will be upgraded by building and installing OpenIPMI driver modules using DKMS. - DKMS build module: Building "openipmi" module version 33.13.RHEL4.

Did you even try googling? second result (direct link and a suggestion and a possible solution. In other words it may be trying to make the driver for an older kernel. Beats me why IPMI would be required for installation though.... at most it should be an addon --⁪froth T C  21:39, 16 October 2006 (UTC)
