• Strange sound from Laptop, Microphone, Speakers or Soundcard?

  - by David Schilling

  I have recently purchased a second hand computer. There didn't seem to be anything wrong with it on purchasing, however recently I have noticed a small issue. Any time I play sound or listen through my headphones, I can hear what seems to be the CPU working (ie when beginning a new task, there is a small crackling). Also if I tap my laptop I can hear the sound louder, as if it is being picked up by the mic and then playing that sound in real time through the speakers or headphones. I have tried reading other topics but cannot find an answer to this question. These are the specs I am running on; Windows 7 Home Premium 32bit Pentium Dual Core CPU T4300 @ 2.10Ghz 2.10Ghz I hope someone can help me with this issue, it would be much appreciated.

• Gnome - windows always open top left

  - by BobTodd

  I find this a highly annoying "feature" on a wide screen monitor that my mostly used apps - terminal and gedit always open directly under the top-left corner of my screen and I have to drag them to my eye position each and every-time. I have tried installing the CompizConfig Settings Manager and using the feature to position windows centre, but this has had no effect - the force feature here isn't working for me either. I can use e.g. gnome-terminal --geometry=140x50+50+50 for the terminal but this doesn't work for gedit. Any ideas? Thanks

• Why is idle windows VM using so much CPU?

  - by Jeff Shattock

  I have 2 VMs running as guests on a KVM virtualization platform running on Ubuntu 10.04. One VM is an Ubuntu 10.04 system, the other is a Windows 7 system. When both machines are completely logged out, the Linux machine uses 1% CPU, the Windows one 45-50%, according to top. The graphs in virt-manager seem to back this up. Theres nothing installed on the Win7 image that would be running in the background; its as fresh as can be. Why is the Windows VM using so much more than the Linux VM, when both are logged out and idling?

• bluetooth doesn't recognize mouse (and other devices)... sometimes

  - by Angelo

  I have a problem with bluetooth with Vista, running on my MacBook. It often doesn't recognize my wireless Magic Mouse. And I saw that it even doesn't seem to start as the pictogram in the task-bar isn't there most of the time I run Vista. But I'm only an Apple-nerd, so I don't know to much about this issue on Vista. When reinstalling Boothcamp or other updates, then once in a while bluetooth recognizes my own mouse (and other devices from some neighbours... so that implicates that the problem must be the bluetooth function in the first place, not my mouse.) Is there some update for the bluetooth application? Angelo

• information about /proc/pid/sched

  - by redeye

  Not sure this is the right place for this question, but here goes: I'm trying to make some sense of the /proc/pid/sched and /proc/pid/task/tid/sched files for a highly threaded server process, however I was not able to find a good explanation of how to interpret this file ( just a few bits here: http://knol.google.com/k/linux-performance-tuning-and-measurement# ) . I assume this entry in procfs is related to newer versions of the kernel that run with the CFS scheduler? CentOS distro running on a 2.6.24.7-149.el5rt kernel version with preempt rt patch. Any thoughts?

• How do I kill a process that keeps respawning?

  - by terabytest

  I got infected by a virus. It looks like I removed it, but it somehow injected a few more processes (I can see them in the task manager) that respawn when I kill them (somehow). Is there a way to destroy those process to stop them from respawning, or in the case something else is respawning them, to kill that "something"? I really don't want to format my pc for this. The data in it is very important for me (personal value) so I'd really want to know a way to do this without reinstalling my OS. I'm on Windows Vista 32 bits.

• Why am I seeing excessive disk activity when installing applications?

  - by Kev

  I'm running Windows 7 Ultimate 64 bit on a Dell Vostro 1720 with 8GB of RAM, 7200RPM Disk, 2.53 GHz Core2Duo (Windows 7 64 bit is a supported option and the laptop came with the OS pre-installed). I'm noticing some fairly excessive disk activity when running installers. For example the Visual Studio 2010 RC installer constantly accessed the disk for ~10 minutes. It was so excessive that I was unable to use the machine until this ceased. Today I installed Trillian Astra 4.1 for Windows (latest build from the website). Again when I ran the installer I was pretty much locked out of the machine until the disk activity calmed down. In both cases when I eventually managed to launch task manager I could see that the CPU was sitting at around 5% to 7% utilisation whilst this was going on. All other disk related activity is fine, the machine is snappy and applications launch without delay. It's just when I run an installer I see this odd behaviour. Why would this be?

• Booting a GPT USB key on older BIOS laptop

  - by fonix232

  I have an old HP EliteBook 8530p, which does not support booting from GPT USB (GPT HDDs are fine though). Lately I had the wish to have a fast-to-start OS for browsing, smaller web tasks, etc., so I grabbed a ChromeOS build (latest one by ArnoldTheBat), flashed it on an 8GB flash drive, and popped it in. It did not boot, so I dug deeper and discovered that it actually is GPT, and cannot be converted to MBR. As my laptop does not support UEFI booting from USB (there's a really-really beta UEFI support in the BIOS, but as I said, it only supports GPT hard drives, not USB devices), I'm stuck. Is there any way of booting it, say, another flash drive with a specific boot loader/manager (e.g. Plop)?

• Is there a free tool/package that can monitor web traffic and display URLS accessed? [closed]

  - by Anthony

  I couldn't find a similar question but then maybe I am searching for the wrong terms. A few years ago I used a router like device, I'm pretty sure it was a SonicWall, that did this on a clients site. Basically all traffic would be routed through this device and it allowed the manager/administrator to inspect web usage of the workers, determine how often certain resources were accessed and block them if necessary (much like content filter). It showed reports based on domain name reached etc. Facebbok.com, Bebo.com and so on. It also displayed the usual IP traffic information etc. it was a UTM also. I have tried Endian firewall, with it's NTOP install, but I don't think that will show URLs browsed. Maybe I just haven't found it in NTOP yet? I need this to troubleshoot connection and traffic issue at my home, with about twenty devices/users so didn't want to buy a dedicated solution and have spare hardware to use a community product.

• How to mount a cdrom to a kvm/qemu domain?

  - by ??O?????

  I have set up a virtual machine running Windows XP on my Ubuntu laptop. Using the virt-manager GUI application, I can insert a CD in my drive and go to Details?IDE CDROM 1 and click on the Connect button. Then the CD becomes available in my virtual machine. How can I do the same through the command line? Obviously, I'd like to be able to disconnect from the command line too. Note: I can start the VM from the command line using virsh start testbed (testbed being the name of the domain/VM).

• SCSI driver installation trouble

  - by Vicky

  I tried to install the driver of Adaptec 39320A-Ultra 320 SCSI card in Win2003 Server R2 SP2 in a DELL PowerEdge 2950 Server. I selected the driver from the list of drivers present in windows. But it says that the device could not be started(Code 10). I tried to put the card in a system that already had the driver installed. It worked fine. So there is no problem with the hardware. I even tried downloading the driver from the manufacturer website. When I try to select install from path and install that driver, it tell no matching driver found. When I install the default driver from windows, it shows the card in SCSI group of device manager, but with an ! symbol. Also the device ID in driver details was different from that of the one present in other system where it insalled fine. Any suggessions to solve it?

• How to debug high memory usage by registry?

  - by bkr

  I have a windows 2008 r2 server running ADFS2 and some web apps that is having issues with low memory. Digging around I found that the 5.5 GB were being used under Kernel Memory (paged). Further digging with Poolmon, I discovered that the majority of that (5GB+) was being used by CM - configuration manager. Also known as the registry. I'm really now sure how to tell why the registry is using so much memory however, or how to release it? Looking at the physical registry files they don't appear that large. EDIT #1 Using the powershell script @ http://jdhitsolutions.com/blog/2011/05/get-registry-size-and-age/ confirms what I saw looking at the physical registry files, that they're relatively small Computername : (removed) Status : OK CurrentSize : 67 MaximumSize : 2048 FreeSize : 1981 PercentFree : 96.728515625 Created : 4/1/2011 11:38:02 AM Age : 454.23:41:28.2540682

• bridge to share WiFi internet connection over eth0

  - by rubo77

  In this script there is implemented that you create a mesh network and connect other machines to your device to serve an internet connection with dhcp: echo "starting bridge to share internet connection over eth0" ifconfig eth0 up promisc brctl addbr br-freifunk brctl addif br-freifunk bat0 brctl addif br-freifunk eth0 echo "internet starting, this may take some minutes due to latency..." echo "(use" echo "tail -f /var/log/syslog" echo "in another window for debugging)" echo echo dhclient br-freifunk echo "The error 'Rather than invoking init scripts through /etc/init.d...' can be ignored:" dhclient br-freifunk # without bridge: dhclient bat0 This works fine with the freifunk-mesh network. But how can I serve internet in a normal case? I would like to connect to any open Wifi I find with my network-manager or wicd (yes, with the graphical GUI) and then start a small script that creates a bridge to my network-out on my laptop I use Ubuntu and my networkcards are eth0 and wlan0

• How to install Windows 8 in a system which has Ubuntu 12.04 and Windows 7 installed already?

  - by Vignesh Palani

  I have a system in which I have installed Windows 7 first. I then installed Ubuntu 12.04 to the system. Now, the boot manager is GRUB Loader and everything works fine as Ubuntu detected that Windows 7 has been installed already. Now, I would like to install Windows 8 too. I plan to install using a bootable USB stick(doesn't matter which medium I prefer though. Does it? ). I have done some research and all the materials I can get state that I cannot practically install Windows 8 after Ubuntu and get all the three OSs to run. Can you help? I want all the three Operating systems to work perfectly.

• How to archive Exchange mailboxes remotely?

  - by amyassin

  We have an environment that is based on an Active Directory domain (running Windows Server 2003 SP2), an internal email system using Exchange Server 2003 (internal mailbox, nothing online), and the clients run a mixture of MS Outlook 2007&2010, with the majority running 2007. Recently we noticed that Exchange server is taking so much space for mailboxes. We are examining some solutions to reduce space, and it seems that we could make use of the archiving feature to archive older messages. I can set the auto-archive option manually for every individual user, but is there any other easier way to automate that task? Is there any feature in exchange server or active directory domain that enables setting that as a kind of policy or something similar, or a script to be scheduled to run by all users?

• How to make fonts smooth and readable in Debian/Ubuntu?

  - by jmdeldin

  What is the best, most foolproof way of getting nice font rendering in Linux? Currently, I am experiencing thin, ugly fonts (shown below). I have wasted too much time tweaking fonts.conf, and I have yet to find a decent combination. I am running Debian 6.0 with no desktop environment (just Openbox for a window manager) in a VM on a Macbook Pro (OS X 10.7.4). Screenshots The following screenshots were taken without fonts.conf and .Xdefaults tweaks. running in "native" Openbox environment: http://i.imgur.com/10bnH.png running over X11, which looks a little worse than Openbox: http://i.imgur.com/sq8jk.png Thank you!

• ping alternative to measure routing distance (on Windows)

  - by Marco Demaio

  Hello, in order to measure aprroximately the rouitng distance (to see if a server is close to my country or too far away) I usually use ping command. I'm in Italy, when I ping Italian servers I get 36ms when I ping US EAST servers I get an average of 120ms when I ping US WEST servers I get an average of 200ms etc. Unfortunately some web hosters turn off the ping reply on their servers, so my question is how do I detect the routing distance, is there another easy to use command in Windows to accomplish the same task? Thanks!

• Problems with webcam

  - by Murtaza

  My friend is using Windows 8.1, and he has a webcam. He says it is working very well even without installing drivers. Webcam is A4tech - PK-331F. I asked for this webcam for use. I plugged in the webcam, and Windows detected it and installed drivers automatically. Then I opened Skype to check the webcam. I got a message from Skype that said, "Your webcam has microphone." When I clicked over it, it directed me to sound settings where it showed that the webcam microphone was working. I went to video settings, but the webcam wasn't listed there. As you can see in the image, the webcam is not listed. It is listed in Device Manager but isn't listed in Skype. I am using Windows 7 Professional. Any idea why this is happening?

• Rebuild an existing Rackspace server from scratch?

  - by Mojo

  In the process of working out kinks in a server build, is it possible to re-bootstrap a server from scratch, image and all? (Same flavor, say.) By that I mean without recreating the server, keeping its IP address if nothing else. I can't find a way to do this. It would have some advantages, I should think: It wouldn't decrement the 'server create' quota. The existing server would keep its IP address. One machine of a cluster could be rebuilt to a new image without having to change the IP address. (Maybe load balancers make IP addresses a moot point, but it still seems like a worthwhile task.)

• Are VLANs necessary for my environment?

  - by kleefaj

  Greetings. I'm the new network manager for a school. I've inherited an environment made up of several Windows servers, about 100 Windows clients, ten printers, one Cisco router, six Cisco switches, and 1 HP switch. Also, we're using VoIP. There are four floors in our building. The hosts on each floor are assigned to a separate VLAN. An office on the first floor has its own VLAN. All the switches are on their own VLAN. The IP phones are on their own VLAN. And the servers are on their own VLAN. For the number of hosts on the network, are all these VLANs really buying me anything? I'm new to the VLAN concept but it seems overly complicated for this environment. Or it's genius and I just don't get it. Any thoughts? Thanks, Jeff

• Automatically cycle numerous or large files to the trash

  - by minameismud

  I've been tasked with fixing a vendor's program that, under certain conditions, dumps gigs of junk files into a log directory. It ends up filling users' machines. My task is to figure out how to make it stop without any source code or additional running processes, and without making the program kasplode. In other words, I'm looking to use a feature of the file system to control the growth. One idea I had was to make a hard link from that folder to NUL, as you might with /dev/null in the linux world. However, my attempts to use the mklink program to create a junction result in a message that says Local volumes are required to complete the operation. Any ideas on how to complete the junction, or other ideas to solve the problem?

• How can I copy the output from a remote command into the local clipboard?

  - by cwd

  I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.
