I need a utility (preferably free) that will allow me to monitor all the traffic on my network ie. sites that client machines are visiting, bandwidth i/o. I don't have the ability to install any software on the client machines themselves.
Suggestions?
Thanks in advance.

Earlier I posted this:
The response was that I should get an updated version of flash player. Implausible from where I'm sitting, but I did so, with no effect at all. Why this happens with such frequency with videos I've recently watched and so seldom with older videos isn't explained. But here's a new data point: A blogger posted a link to a youtube video. I watched it while looking at the blogger's web page. When I clicked on "watch on youtube", bringing up a separate browser window, I got the same blank white screen that I'd seen before. Then I went back to the blogger's page and I could still view the video. Michael Hardy ( talk) 04:38, 22 February 2011 (UTC)
I've tried three different browsers, with identical results: internet explorer, firefox, and google chrome. Michael Hardy ( talk) 16:32, 23 February 2011 (UTC)
How do supercomputers use multiple motherboards? Would the same technique be practical for home use, so it would be possible to have multiple graphics cards, more RAM, multiple CPUs, etc.? -- T H F S W ( T · C · E) 05:16, 22 February 2011 (UTC)
To answer the original question, take a look at Beowulf (computing). This is the most straightforward way that you, as a home-user, can construct a "multi-motherboard supercomputer." If you start applying your compute resources to a particular problem with special needs, you might find that beowulf clusters have unsuitable performance - but for many types of computer problems, a cluster is faster than a single machine. Nimur ( talk) 16:15, 22 February 2011 (UTC)
If you want to construct a Beowulf cluster at home, all you need are multiple identical PCs connected to an Ethernet switch, and a Networked-Attached Storage device. (I'm presuming that the PCs will boot locally, as otherwise you will a Storage Area Network, which gets more complicated). And you'll need a console switch to manage all the nodes from a single console. Rocketshiporion ♫ 08:37, 23 February 2011 (UTC)
Is it possiblt to extend Microsoft Update in Windows 7 by adding non-MS update sources? (like Firefox, for example) -- 91.4.234.221 ( talk) 10:50, 22 February 2011 (UTC)
Currently my several-years-old WinXP SP3 computer has a DVD RW drive and a CD RW drive, both internal. I would like to replace the CD RW drive by a DVD ROM drive, so that I can make spare copies of my backup data disks.
What do I need to do regarding changing the jumper settings on the drives so that there will not be any conflict? Thanks 92.15.8.100 ( talk) 13:25, 22 February 2011 (UTC)
Thay are the older PATA type, also called IDE I think, taken from another old computer, and there is no sticker to be seen.
Are jumper settings standardised? The drives have the same three possible jumper settings. Is there any standardisation over what the three positions mean? Thanks 92.15.2.21 ( talk) 21:40, 22 February 2011 (UTC)
Is there any easy standard way of making DVD data disks used for backup secure, in other words they need a password to be supplied?
Past experience has taught me that wrapping everything up in a huge multi-GB password protected zip file is not the way to go. Is there any other way? Thanks 92.15.8.100 ( talk) 13:33, 22 February 2011 (UTC)
Are there any standard ways of creating files that have extra fault-tolerant redundancy built in, so that they are still readable even if they were, for example, copied to a writeable DVD disc with errors? Thanks 92.15.8.100 ( talk) 13:37, 22 February 2011 (UTC)
So the short answer is "No". Pity. Thanks 92.15.2.21 ( talk) 21:41, 22 February 2011 (UTC)
Thanks, although from reading the link and its links, it looks like it needs to mature some more before it becomes reliable and trustworthy. 92.29.115.56 ( talk) 10:46, 23 February 2011 (UTC)
Thanks, DVDisaster looks interesting. The achille's heel of discs would I suppose be the directory structure, since there is only one copy of it. Unless no directory structure is required for a simple file at the root of the disc? That file could be a zip file with a directory structure within it. 92.24.188.45 ( talk) 18:08, 25 February 2011 (UTC)
Is it possible to make a .bat file run all .bat files in another folder one by one? The idea would be to have a folder of .bat files which do various things, and only need to start one .bat to make them all run, and if I add or remove any of the .bat files the script won't need editing 82.43.92.41 ( talk) 15:55, 22 February 2011 (UTC)
I urgently need to copy a DVD someone recorded with their camcorder. It is not a commercial recording and has no copy protection. I cannot find any DVD copying capability in the various programs on my PC which seem related to media. Googling "DVD copying" just leads to discussions of how to defeat copy protection by buying some expensive program. What program I already have, or what reputable freeware program, would allow me to make a copy of a DVD? I have Express Burn, Windows Movie Maker, Windows Media Center, Windows Media Player, RealPlayer SP, Itunes, Replay AV 8, and Quicktime. Thanks. Edison ( talk) 16:25, 22 February 2011 (UTC)
Hello everyone!
I need help of you people,i have a very strange problem in firefox 3.613,when i am browsing the net it stop working for a few seconds and

plugins also installed.Any help will be appreciated.Thank You! —Preceding unsigned comment added by 119.154.116.124 ( talk) 18:41, 22 February 2011 (UTC)
This is a question about using Wikipedia, moving to the help desk. The question is now available at Wikipedia:Help desk#Upload Image to replace old one. JIP | Talk 19:50, 22 February 2011 (UTC)
... that only returns a single result when it is searched with Google or another search engine? I dimly remember that searches for this kind of (real-life?) words is a kind of contest and that those words even got a specific name that has possibly an entry on Wikipedia, but I do not recall any more details... Does my description say anything to anyone? regards, Grand-Duc ( talk) 20:35, 22 February 2011 (UTC)
when i first got my iPad a month ago all of the wikipedia pages came up in mobile format. I noticed within the last couple of days it changed to full page format. If I prefer the mobile, how can I get pages to display that way? Lastly, do you know why it changed to full version without asking me? By the way I tried your help desks live chat and they recommended I ask the question here. Thanks for helping me! 98.255.194.166 ( talk) —Preceding undated comment added 21:34, 22 February 2011 (UTC).
Would I have to do that every time I open a wikipedia page or is there a way to make the iPad default to mobile pages? When I first got the iPad it was doing that automatically 98.255.194.166 ( talk) —Preceding undated comment added 15:51, 24 February 2011 (UTC).
Do the date and time functions in greasemonkeys javascript on firefox conform to the timezone of the computer it's run on, or does it use something else like UTC so it's standard across any computer? For example;
String((new Date()).getTime()).replace(/\D/gi,'')
