• Max. Temp. on Intel Burn Test for Stock Dell Precision T3500

  - by HK1

  I'm troubleshooting an issue on a Dell Precision T3500. As part of my troubleshooting I've decided to try running a stress test using Intel Burn Test software. This machine is a stock configuration with 12GB of RAM and a Xeon W3670 processor (nothing overclocked). When I run IBT using the standard mode, SpeedFan reports a processor temperature in excess of 80C. I've seen numbers as high as 90C but even at that temperature the machine does not become unstable or crash. However, it seems way too high. This processor has a TCase of 67.9C according to Intel's website. I'm guessing that means I'm in the danger zone any time I go over that temperature. I've checked the cooling system and everything looks fine. I've even took out the heat sink and reinstalled it with new thermal compound. This did not appear to make the problem better or worse. Is there a discrepancy somewhere here in the way temperatures are measured or displayed? I've also tried using HWMonitor from CPUID and it reports the same temperatures. Should I just let the Standard Test go and disregard the temperature outputs?

• How to verify system using right GPU, after system reset [duplicate]

  - by Antoros

  This question already has an answer here: Is my mobile AMD card being used? 2 answers OS: Windows 8 CPU: Intel® Core™ i7 Processor 3635QM GPU 1 : Intel HD Graphics 4000 GPU 2 : AMD Radeon™ HD 8870M other info: System Spects Problem: im unsure that CCC is using AMD card instead of Intel's, i have encountered several issues since updating to 8.1 and i don't know what to do What happened: Installed 8.1 patch first day After 1 minute of use, BBSOD, windows never loaded again System restore wouldnt recognize 8.0 restore points i did a system reset to windows 8 since the laptop was only 3 weeks old System Broke, it did restore to factory BUT kept the registry almost intact, i had to install almost everything again, since the factory drivers where working with the updated one's registry and several problems CCC Broke too <- What i've already done Installing new drivers on top of old ones didnt work, so i used AMD uninstaller first Uninstalled and Re-installed Intel's HD Graphics Driver Tried to install mobile center, but AMD told me that it wasnt compatible (even if thats the only driver that they provide via their page as seen Here) Tried to use Auto-Detect, couldnt install driver because card was disabled because it didnt have the drivers... (see what they did here?) Had to use a workaround with Samsung Update, the driver didnt appear as download so had to use search and downloaded the driver manually. Now the graphic card appears on device manager and catalyst but as 8800 series (not exact model), and cant check the card with neither dxdiag/GPU-z/HWMonitor when right-clicking on CCC only Intel card appears launching a game and using as "high performance" would speed it up a little but i cant be sure How to verify its working properly? HWMonitor wont show AMD card even when set to high performance Latest GPU-Z wont work because a problem with Intel's, and legacy ones wont either what can I do now? I don't even know if I fixed my problem or not, and i also want to to use Adobe Premier with it, and its locked (the option to run it with the amd card not intels) Edit: now it seems to work, but cant change the setting for adobe Premiere and other programs that i Need to

• Why do moving lines become fuzzy on my monitor?

  - by CodeInChaos

  I recently got a new notebook. With moving images there are some graphical issues, and I'd like to know what causes them. None of my earlier monitors exhibited similar issues. Moving high contrast lines become jagged, similar to interleaved videos. When moving a horizontal line vertically those artifacts are colored, when moving a vertical line horizontally they aren't colored. The effect isn't observable in static images. And when moving faster the zone in which it occurs becomes wider. The effect is very visible if I move a window around on the borders of the window and wherever high contrast lines appear. But it appears when watching videos too. The vertical line in that image moves to the right, the horizontal line upwards. The effect is most likely related to the fact that each real pixel consists of different sub-pixels for the different color channels. But how are these causing the observed effect? Is the change at which the different colors change to the destination brightness different? The optical impression is that every second pixel in a chess board like arrangement is adapting slower than it's neighbors. But that doesn't make much sense.

• VMWare use of Gratuitous ARP REPLY

  - by trs80

  I have an ESXi cluster that hosts several Windows Server VMs and around 30 Windows workstation VMs. Packet captures show a high number of ARP replies of the form: -sender_ip: VM IP -sender_mac: VM virtual MAC -target_ip: 0.0.0.0 -target_mac: Switch interface MAC The specific addresses aren't really a concern -- they're all legitimate and we're not having any problems with communications (most of the questions surrounding GARP and VMWare have to do with ping issues, a problem we don't have). I'm looking for an explanation of the traffic pattern in an environment that functions as expected. So the question is why would I see a high number of unsolicited ARP replies? Is this a mechanism VMWare uses for some purpose? What is it? Is there an alternative? EDIT: Quick diagram: [esxi]--[switch vlan]--[inline IDS]--[fw]--(rest of network) The IDS is complaining about these unsolicited ARPs. Several IDS vendors trigger on ARP replies without a prior request, or for ARP replies that have a target IP of 0.0.0.0. The target MAC in these replies is the VLAN interface on the switch. Capture points: -The IDS grabs the offending packets -The FW can see the same ones -A VM on the ESXi host does not see these, although there is an ARP request for a specific IP on the ESXi host that has source_ip=0.0.0.0 and source_mac=[switch vlan interface]. I can't share the captures, unfortunately. Really I'm interested in finding out if this is normal for an ESXi deployment.

• Serious 64-bit laptop

  - by Daniel Gehriger

  For the past couple of years, I have been using an IBM Thinkpad T60p for daily work (software development, desktop & embedded). I am extremely satisfied with this machine, due to its robustness. It also has a few features I depend on: a high resolution display: 15.0" TFT FlexView display with 1600x1200 (UXGA); excellent keyboard; decent graphics and CPU performance. Some of the software I develop benefits from larger amounts of RAM, and 3GB (Windows 7 32-bit) or 4GB (Windows 7 64-bit on T60p) are no longer sufficient. My customers run desktop computers with 20GB and more, and I need to have at least 8GB to at least be able to run reasonable test cases. So I'm shopping around for a new laptop, but I'm struggling to find anything that matches my requirements: must run Windows 7 64-bit Pro or higher; must support at least 8GB of RAM (more is better) high screen resolution! While I prefer 4:3 I can live with wide screen. But I really hope to find something with a vertical screen resolution similar to what I have now... portable, so < 16" but = 14" I realize that FlexView isn't available anymore, but I'd like to avoid a glossy screen if possible. decent (not more) graphics performance, ideally hybrid (I'm doing a lot of CAD, never games). good keyboard reasonable CPU -- but I'm still fine with my current Core 2 Duo, so that shouldn't be too complicated. The T60p fits all those requirements, except the 8GB of RAM. Can you help me find a current notebook that would match most of them? I don't mind changing brand. Thanks!

• How can I stop SipVicious ('friendly-scanner') from flooding my SIP server?

  - by a1kmm

  I run an SIP server which listens on UDP port 5060, and needs to accept authenticated requests from the public Internet. The problem is that occasionally it gets picked up by people scanning for SIP servers to exploit, who then sit there all day trying to brute force the server. I use credentials that are long enough that this attack will never feasibly work, but it is annoying because it uses up a lot of bandwidth. I have tried setting up fail2ban to read the Asterisk log and ban IPs that do this with iptables, which stops Asterisk from seeing the incoming SIP REGISTER attempts after 10 failed attempts (which happens in well under a second at the rate of attacks I'm seeing). However, SipVicious derived scripts do not immediately stop sending after getting an ICMP Destination Host Unreachable - they keep hammering the connection with packets. The time until they stop is configurable, but unfortunately it seems that the attackers doing these types of brute force attacks generally set the timeout to be very high (attacks continue at a high rate for hours after fail2ban has stopped them from getting any SIP response back once they have seen initial confirmation of an SIP server). Is there a way to make it stop sending packets at my connection?

• Is there an application to log component temperatures to file?

  - by MrVimes

  I purchased a computer a month or two ago (core i7, 24gb ram, geforce gtx 590, windows 7 ultimate). Within the last week it began to bluescreen regularly. I tried lots of things (check hds, check memory, reinstall windows etc..) but it still bluescreened. At the time my temps were as follows... CPU - aprox 40/50c. GPU - arpox 60 idle, aprox 90 during heavy use. HDDs - aprox 55c after the PC had been on a while. I thought the 55c was ok, but I have since realized it was probably too high and may have been the direct cause of the bluescreening. I've installed a spare fan I had in the front of the PC blowing air in, (so there's airflow from front to back) Since then, obviously, all my temps are down. Especially the HDDs - three of them reach 30c and one has been up to 47c (it is some distance away from the airflow, in one of the 5.25inch drive bays) I haven't had the PC on for as long as it would normally take to bluescreen yet, but If it does I want to know what all the temps were right before the bluescreen. I have tried Everest but it only shows me realtime temps or gives me the ability to create one-off reports. I want something that can record all the temps to a file at 30 seconds intervals. If the computer bluescreens I can load it up again and check the last entry in the file. Side question: Am I right in thinking 55c was far too hot for a HDD? (It might have got higher than that before the bluescreens.. I don't know) Another side question: Is 47c too high? This is actually why I am asking the main question - I am concerned that this one drive that isn't getting the benefit of the extra fan may still cause the computer to bluescreen.

• Why does apache httpd tell me that my name-based virtualhosts only works with SNI enabled browers (RFC 4366)

  - by Arlukin

  Why does apache give me this error message in my logs? Is it a false positive? [warn] Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366) I have recently upgraded from Centos 5.7 to 6.3, and by that to a newer httpd version. I have always made my ssl virtualhost configurations like below. Where all domains that share the same certificate (mostly/always wildcard certs) share the same ip. But never got this error message before (or have I, maybe I haven't looked to enough in my logs?) From what I have learned this should work without SNI (Server Name Indication) Here is relevant parts of my httpd.conf file. Without this VirtualHost I don't get the error message.

• HP/IBM alternative to Buffalo iSCSI TerraStation?

  - by Robin Day

  I'm looking at virtualising some of our infrastructure in order to allow for more resiliance and future expandability. We have successfully virtualised on single servers with Direct Attached Storage and are now looking for a more future proof solution using a high powered host (or two) and a SAN (or two). I'm thinking that the host machine will probably be an HP ProLiant DL360 G7 (all of our exisiting infrastructure is HP). Unfortunately, I am new to the world of SANs. From what I can see, the Buffalo Terrastation III is all I would need in order to setup an iSCSI SAN for VMWare to use. However, I'm a little reticent to go that way as it's a bit too "entry level" for my liking. In particular I would be very keen for more redundancy, power, networking, etc. I'm also very aware that you "get what you pay for". Therefore, can anyone reccommend equivalents from the big boys? HP/IBM? I have searched high and low on the HP site and seen many options but am struggling to work out if it is all the hardware I will need. Some options appear to need separate controllers from disk enclosures, etc.

• Extend Linux Desktop to another X Windows Display

  - by unknown (google)

  Hello, I am a long time Linux user of the Xinerama and other technologies for extending a desktop to multiple monitors. However when I travel with my laptop I miss the multi-monitor support I enjoy at home. Recently I acquired a second laptop for a low price. Both laptops are running Fedora (versions 10 and 11 respectively). I use Gnome as my primary desktop environment. I know about synergy. I use synergy all the time to control the screen of other Windows / Linux systems I use. I would like to know, can I sit both my primary and secondary laptops together and achieve a Xinerama-like extended desktop environment? Ideally I would like to start a GNOME session on my primary laptop. And then start a X-Windows Desktop on my secondary laptop and extend my primary laptop's desktop onto it. I would like to be able to move Windows from the primary desktop to the secondary laptop desktop. Would I need to use synergy to do this with some other bit of X-Windows technology? Or is there X-Windows technology that will do all this for me? I am familiar with X Windows ability to display applications remotely. I am also familiar with Nomachine's NoX.

• What is a suitable simple, open web server for Windows?

  - by alficles

  I'm looking for a dead simple web server for Windows. Load will not be high as it will be primarily serving binaries for a WPKG update service. It needs to serve the entire contents of a single folder over HTTP on a configurable (high) port. No CGI or other scripting is required, but it might be nice for future features. I started with Mongoose, since it doesn't even have an installation requirement (a very nice perk), but it fails to start when run as a service. (Technically, it acts as it's own installer.) I've investigated LighTPD as well, but it appears to be minimally (at best) tested on Windows. And naturally, I'm looking for something free. As in beer is good, but speech is better, as always. Edit: I didn't mention this initially, but non-tech people will be doing the install. They'll have whatever script I write for the install, but the goal is a simple system that is easy to troubleshoot. (I almost worded this question "What is the best...", but Serverfault rightly observed that that is a subjective question. And it's really not an optimization problem, any suitable solution will work. I just can't seem to find one for Windows.)

• Network topology for both direct and routed traffic between two nodes

  - by IndigoFire

  Despite it's small size, this is the most difficult network design problem I've faced. There are three nodes in this network: PC running Windows XP with an internal WiFi adapter.Base station with both WiFi and a Wireless Modem (WiModem)Mobile device with both WiFi and WiModem The modem is a low-bandwidth but high-reliability connection. We'd like to use WiFi for high-bandwidth stuff like file transfers when the mobile is nearby, and the modem for control information. Here's the tricky part: we'd like the wifi traffic to go directly from the mobile to the PC, as rebroadcasting packets on the same WiFi channel takes up double the bandwidth. We can do that with a manual configuration by giving the both the PC and the base station two IP addresses for their WiFi interfaces: one on a subnet shared with the mobile, and one on their own subnet. The routes on the PC are set up so that any traffic going to the mobile via WiModem goes through the secondary IP address so that return traffic from the mobile also goes through the WiModem. Here's what that looks like: PC WiFi 1: 192.168.2.10/24 WiFi 2: 192.168.3.10/24 Default route: 192.168.2.1 Base Station WiFi 1: 192.168.2.1/24 WiFi 2: 192.168.3.1/24 WiModem: 192.168.4.1/24 Mobile WiFi: 192.168.3.20/24 WiModem: 192.168.4.20/24 We'd like to move to having the base station automatically configure the mobile and PC, as the manual setup is problematic when you start having multiple mobiles and PCs. This means that the PC can only have 1 IP address and needs to be treated as being pretty simple. Is it possible to have a setup driven by DHCP on the base station that is efficient with bandwidth?

• At what point does the performance gap between GPU & CPU become so great that the CPU is holding back a system?

  - by Matthew Galloway

  I know that generally speaking for gaming performance the GPU is the primary factor which holds back performance, with everything else such as RAM/motherboard/PSU/CPU being secondary in importance to the graphics card. But at some point the other components ARE going to be significant in holding back the whole system! For instance nobody would be silly enough to play modern games with 512MB RAM and the very latest graphics cards (such as an HD7970) as I bet the performance increase over such a system with only 512MB but a mid range card would be non-existent! Thus it would be a "waste" for such a person to buy any high end graphics card without resolving first the system's other problems. The same point applies to other components, such as if it only had a Pentium II a current high end graphics card would be wasted on it! So my core question is how do you determine at what point for your system is spending on extra GPU power be completely "wasted"? (also, a slightly more nuanced question is trying work out at what point might the extra graphics power not be "wasted" but would be "sub optimal" value for money, when the expenditure should then be split around graphics card and other components. As obviously a gamer shouldn't always just spend on upgrading the graphics card! But needs to balance it out)

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by user53575

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 16000x12800 pixels. My laptop's screen has a native resolution of 1280x800. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work? Here was an answer: http://superuser.com/questions/120266/how-can-i-take-browser-screenshots-at-a-higher-resolution-than-my-browser-support But it doesn't work. Firefox remains in the resolution of the physical screen. The window blinks and shrinks back to normal resolution. Please Help!!

• AMD processors witn graphics card bundled [closed]

  - by shybovycha

  Sorry for posting this question here - just don't know to which StackExchange website i should be writing. I've heard AMD created processors with video card bundled. So now these processors should work as fast as just usual processors with discrete video card but AMD's ones should use less power and spread less warm. Some googling around gave me the result like "AMD processors of A-series". They were mentioned to be build using that technology i described above. But on the other hand, we have a small rate of publishing and not-very-good quality of AMD drivers. I am a game-developer and web-developer so i need a powerful processor and graphics card and a lot of RAM on board (to make it possible to create a sample Grails application, for example or to create some 3D models in Maya/Cinema4D, for instance). Still i want my battery to be a long-living one, so power usage is a bit critical for me. So, my questions are: are there any processor building technology like i've described and which series they are (if they exist)? which processor shall fit the laptop the best: AMD one or i5/i7 on with nVidia graphics card for the purposes mentioned above?

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• [SOLVED} How do I restore my audio after uninstalling Ventrilo?

  - by Marcx

  Hi, I've a Dell studio 1555 bought on september with Windows 7 64bit Professional on it. The audio device works proprerly, while listening to audio contents (from disk or internet) When I use Ventrilo, the audio from other people sounds good and I hear their voices clearly When I use any other VOIP programs like Teamspeak 3, MSN or Skype, I hear a disturbed voice, and it's impossible to comprehend something... Anyway everything worked fine until I installed Ventrilo, but removing it didn´t solve my problem. Update: Here's a sample of how I hear others people voices.. Audio Sample After some tests, also the desktop has the same problem. (I tried TeamSpeak3) Here are some details on my laptop and desktop Laptop Dell Studio 1555 Core 2 Duo P8600 2.4Ghz 4Gb Ram Dual Channel Ati HD 4570 512Mb dedicated (up to 2048) IDT High Definition Audio Desktop Motherboard Asus P5KPL-AM Dual Core CPU E5200 2.50Ghz 2x2GB PC6400 Dual Channel Ati Radeon HD 4650 512MB VIA High Definition Audio Both computers have Windows 7 Professional 64Bit. So how do I restore my audio? SOLVED The problem was in router firmware, there was a bug that recognized VoIP traffic as a DOS attack and the router grambled every packet... I've installed the newest firmware and everything is fine :)

• Which components should I invest in.. for a backup machine.

  - by Senthil

  I am a freelance developer. I have a PC, a laptop and an old testing and file server machine. I might add one or two in future. I want to have an on-site backup machine that can handle backups of ALL these machines - file backups, MySQL backups, backup of subversion repository, etc.. When building the machine, which components should I invest more in? Examples: The cabinet should have lots of room for expansion. Hard disk size should be large. But I guess hard disk speed need not be high (?) But other components like, RAM, PSU, Processor, Network card, Cooling, etc.. how much relative importance do these have in a backup machine? Which of these components should be high-end or large, and which ones need not be? Some Idea of the load: There will TBs of data. File backups and subversion repository backups will at least be done daily. MySQL backups done weekly. assume 3 machines at the moment and somewhere around 10 machines in the future.

• disable specific PCI device at boot

  - by Rhymoid

  I've just reinstalled Debian on my Sony VAIO laptop, and my dmesg and virtual consoles all get spammed with the same messages over and over again. [ 59.662381] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 59.901732] usb 1-1.2: new high-speed USB device number 91 using ehci_hcd [ 59.917940] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 60.157256] usb 1-1.2: new high-speed USB device number 92 using ehci_hcd I believe these messages are coming from an internally connected USB device, most likely the webcam (since that's the only thing that doesn't work). The only way I can seem to have it shut up (without killing my actually useful USB ports) is to disable one of the USB host controllers: # echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci_hcd/unbind This also takes down my Bluetooth interface, but I'm fine with that. I would like this setting to persist, so that I can painlessly use my virtual console again in case I need it. I want my operating system (Debian amd64) to never wake it up, but I don't know how to do this. I've tried to blacklist the module alias for the PCI device, but it seems to be ignored: $ cat /sys/bus/pci/devices/0000\:00\:1a.0/modalias pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 $ cat /etc/modprobe.d/blacklist blacklist pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 How do I ensure that this specific PCI device is never automatically activated, without disabling its driver altogether? -edit- The module was renamed recently, now the following works from userland: echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci-pci/unbind Still, I'm looking for a way to stop the kernel from binding that device in the first place.

• How can I get DVDs playing after a Vista to XP change?

  I replaced my vista install on a Dell Inspiron 1525 with XP and have managed to get most things up and running again however I'm having trouble with playing DVDs. When I try and play a DVD I get the following message: Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card. I have ensured that my drive is configured to play Region 2 discs (I'm in the UK), I've installed the most up to date XP codec pack which makes me think it's a driver issue. In device manager I have got my DVD drivers up to date however under "Other Devices" I'm missing several which sound key: Audio Device on High Definition Audio Bus Modem Device on High Definition Audio Bus Video Controller Video Controller (VGA Compatible) However I've installed all the relevant drivers I can find on the Dell website.

• ec2 spot instance for daily processing task

  - by chaft

  I don't have much experience as a sysadmin or with amazon aws, so I hope someone can explain in simple terms or refer me to a good guide on how to achieve the below. I have a system running on ec2 and amazon rds getting data in and saving it to the db. I need to run a script once a day (at the end of the day) to process all that data and prepare a daily report. This process will take approximately an hour to run. It needs to run on a high memory instance.. From what i've read so far, I guess the best way to do it is to have a high memory spot instance run every day, set it up to execute the script on startup and and shut down when done. Is that the right way to do it? If so, how to do it? how to tell the spot instance to run every day? through a cron job on the other server or is there a better way? How to set it up to run the script on startup? through cloudinit? Any help would be appreciated. One last thing, the job is not very time sensitive as long as it runs every day.. thanks

The drive itself is working - I've run software from the drive. I'm afraid I am far from a sys-admin so I'm struggling on this one. How can I get my DVDs playing again?

• Building a small server farm

  - by RayQuang

  Hi, I am planning to set up a Tech startup company that will provide web application solutions. Eventually we hope to diversify into different areas such as possibly social media or other services. For now we plan on running a high demand (from 1000 to 10,000 users in the first year) website running the application. This includes a MySQL database backend, email, and development servers. My question is then, what type of server arrangement will work best, that is ti say should i have a small cluster of ultra high power machines (E.G. Top of the range Xeons, with 12GB RAM) or will it be better to have more less powerful servers load balanced? Should I go for 1 - 2 u servers rack mounted ot would it be beter for it just to be tower servers for maintainability? Finally I would also like to know what kind of Internet and router i would need, I currently have 10mbit down and barely 1 mbit up, but soon our area will have a fiber optic connection with international speeds of up to 25 mbit / sec. Thanks in advance, RayQuang UPDATE: sorry I forgot to mention it, the platform that I will be using is PHP with the APC code cache, Probably running Debian.

• Network using only switches

  - by mschultz

  So I'm not a network guy - but here's what I want to do - I have an existing network using wifi, which I like, and which is used to connect several computers to the internet. It is headed up by a router, which is in another part of the building. Three of those computers are in my office. All three have gigabit wired ethernet. I have a gigabit switch. Here's what I want to do: Build a 2nd network, out of just that switch, which allows all 3 computers to connect to each other (just to each other is fine, for this purpose, they need no internet). I have a distributed computing task (rendering high-quality fractal artwork, as it were), that requires the best connection speed to all 3 computers. I want them to be able to "talk to each other" as quickly as possible, with the fewest dropped packets (the dataflow over this network will be quite high). So how do I do this. I'm not a networking guy at all - I tried connecting them all, and nobody got an IP address (which I assume is because nobody is running a DNS server?). What all do I need to do to make this work? PS - two are running windows, one is running ubuntu.

• Perfmon % Processor Time vs. task manager's CPU usage

  - by nat

  I'm new to using Perfmon and performance monitoring in general (so go easy on me please ;) I know that Perfmon doesn't have anything exactly like Task Manager's CPU usage display, but I'm trying to figure out how to monitor user's CPU usage via Perfmon in a similar way, and trying to understand the measurements (or how to convert the numbers to get a similar understanding) For example, if in Task Manager, a particular user is consistently using more than 5% CPU, I would want to contact the user about it. I learn best by example, so here is exactly what I'm trying to do, with a specific example: This is for a 32-bit Dual Quad Core Windows 2003 web server (8 CPUs), there are many web sites on the server, each running within their own application pool/worker process ID. Through other research here I learned of a registry change that I made so that the PID shows up with the w3wp process so I can easily identify the site later by cross-referencing it. I set up a counter with the following settings: Process -> % Processor Time -> all instances Here is an example. Say I'm interested in "black line" user in this graph below, as his process is spiking quite high compared to all the other users: (I wasn't allowed to post the image as I'm a new user on this site.. I've uploaded the image to:) http://i35.tinypic.com/106yn8k.jpg So... using this as an example, I see that they have an AVERAGE % PROCESSOR TIME of 23.264 , and have spiked as high as 103.124 So what exactly does this 23.264 number mean to me? Is it similar to an average of Task Manager's CPU reading for this user? Or, since this server has 8 CPUs, should I divide this number by 8? (23.264/8 = 2.9% AVERAGE CPU LOAD?) Thanks in advance.
