  • kill process but fail

    - by Tim
    Hi, I am running a bash script as a background job. The bash script calls a time-consuming executable. If I am not wrong, the running of the bash script is the parent process and the running of the executable is the child process. I now want to stop the whole running by killing the parent process which is the background job kill -9 $(jobs -p) The terminal shows that the running of the bash script is killed. But the running of the executable still hangs on the output of top. I just wonder how to also kill the child process? Thanks and regards!

  • Excel: Edit the XML inside an XLSX file

    - by Andomar
    An Excel XLSX file is a zip archive containing several XML files. I tried to extract all the XML files, and edit xl\connections.xml using an XML editor. That's because I have to change 20+ connections to point to a different server. When I open the edited archive in Excel, it refuses the changes and repairs the file. Is there a way to edit the XML files inside an XML archive?

  • Blocking internet poker applications

    - by Matthew Savage
    I 'look after' the wireless internet for a cafe where I live, and we've noticed that there's quite a substantial slow down of internet speeds when certain users are playing internet poker. I've put in filters to block any HTTP traffic referencing gambling and poker etc, however I want to be able to block any applications (i.e. poker clients) which don't use HTTP. I've tried searching around for a list of poker clients and perhaps their ports, but have had no real luck. Does anyone know what these might be?

  • What is the command to check if a command's results mention OK?

    - by Manuel
    Alright, so I was playing around with changing MTU size and wanted to make a batch file to automatically lower it and then raise it later. This is probably simple, but I just can't figure it out. Point is, is there a way to run a command, which would normally echo out "ok" but check to see if it does say ok? And if it doesn't say ok then, to end the rest of the file from running and exit out. The command I'm using is netsh interface ipv4 set subinterface "Local Area Connection" mtu=386 store=persistent which, as I mentioned above prints out an OK. I just want to check if it did run correctly, and if not, then do __

  • Format (remove) HDD volume that is visible in Windows 7 Disk Management but not diskpart.exe

    - by EntropyWins
    I'm trying to get iRST working on a SSD I installed in my lenovo u410. As part of that process, I created a hibernation partition and was fiddling around with RAID/AHCI settings. I managed to make my computer unbootable. No sweat, I just restored it with Lenovo's 1 key system. Now, however, I can't do anything with that hybernation partition! I can see it: (It's the 7.81 GB partition). But when I try to delete it in Diskpart.exe to reclaim the space and try the formatting again I only see this: I can't do anything with the partition in Disk Management either. Right clicking only shows the 'help' option. Can anyone suggest a way to edit these partitions with windows or, at least, reccomend a program that might help me fix this? Note, I'd rather not delete the 16 GB OEM partition that I believe holds the backup for this computer.

  • Linux Mint 13 is not booting on dual boot computer

    - by Brian
    thanks in advance for your time. I have 2 hard drives in my computer a 300 GB drive which is my primary drive for windows 7 and a 1.5 TB drive that I'd used for storage. When I got it I partitioned 500 GB for use in Linux. So, I created a bootable USB and clicked the "Install by Current Operating System" option from Mint. It installed it to the free 500 GB like I'd hoped it would. Now, I can't get it to boot though. I've tried using EasyBCD to create the boot entry and it hangs on a black screen. Thanks. EDIT @ Ryhuk It presents a menu with two options 1) Windows and 2) Mint. This was a menu I created with easyBCD. When I select option 1 it boots to windows fine. When I select option 2 it hangs on a black screen with just a white bar flashing (Can't remember what its called, it marks the current cursor location on a text field) and won't respond to any key presses but alt ctrl del.

  • New graphics card (GTX 760) slowing down entire PC

    - by Cayetano Gonçalves
    My new graphics card is making my PC totally unusable. It boots up really slowly, and when the windows screen comes on, the mouse lags really far behind. Nothing opens at a normal speed. However, when I put in my 5-year old graphics card, it all works fine. I'm currently using a Foxconn Renaissance LGA 1366 Intel X58 ATX Motherboard, Intel Motherboard Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Processor, and a EVGA SuperNOVA 850G2 80PLUS Gold Certified ATX12V/EPS12V 850W Power Supply . I know it can't be the power supply, because I just bought it today to try to fix the problem. I've also installed the newest version of BIOS available for my motherboard. I've also seen extreme variations in CPU while the new graphics card is in, and when the old graphics card is installed, it is much calmer. Any thoughts?

  • Cannot activate windows 7

    - by Charlie
    I can't activate Windows 7, I get an error saying DNS name does not exist. Is something configured incorrectly somewhere? PS: I need the answer within 13 days ;) UPDATE: I had upgraded from my company's Windows Vista build, and when I connect to the company VPN and activate I get a different error: The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information. The Application Event Log contains this (I took out the server name, it's one of the company servers): The client has sent an activation request to the key management service machine.

  • Raid HDD Boot up

    - by user234695
    My server is Power Edge 1950 running server 2008 32Bit, using 3 Physical SAS HDD as a Virtual 2 Disk configured for RAID5, with partition of C drive as OS and D drive as Data. Planning to format and install Server 2008 R2 64Bit so I insert a New Physical disk and configured as RAID5 and clone the C drive and D drive to the new hard disk. Now I need to test that the new hard disk is able to boot windows and work as expected. How do I test, I am not able to boot the windows by choosing the new harddisk, the bios show only the existing HDD, not the new one. Also, if I remove the old three hard disk, and leave the new harddisk and then am I able to boot the device, if I do this does my existing RAID5 configuration and data on the hard disk still remain.

  • Sharing Windows 7 Hard drive with Windows XP Hard drive

    - by Ginzo Milani
    I wish to share my hard drives between my two computers but I seem to be running along some sort of error... my windows XP Computer is picking up my "XGaming" hard drive but when clicked it says access is denied, despite there is no password set up(I followed this: http://www.howtogeek.com/howto/windows-7/share-files-and-printers-between-windows-7-and-xp/) I also tried to share my C and J drives on my windows XP computer but my windows 7 computer doesn't seem to even detect them!

  • DNS Resolution doesn't work after uninstalling Cisco VPN & Deterministic Network Enhancer in Win 7

    - by Craig M
    I just upgraded my home PC to Windows 7 Ultimate 32 bit. After trying various methods to get the Cisco VPN client to work, I gave up and decided to just run it in XP mode. The last steps I tried were in this article ( http://social.technet.microsoft.com/Forums/en-US/w7itproappcompat/thread/d880dfe5-7f44-4955-8620-2a9355d8ea8b/ ) After that, I uninstalled the Cisco client and rebooted. I uninstalled the Deterministic Network Enhancer and rebooted again. Both uninstalled successfully, but now I'm not able to resolve any DNS. The only way I can resolve DNS is to reinstall the DNE, reboot, and uninstall the DNE. Then I am able to resolve DNS lookups until I reboot again. Once it's rebooted, no more DNS. Any ideas? Edit: I completely forgot I'd asked this question until harrymc posted his answer. I've since found out that to fix this problem, I need to disable my Local Area Connection and re-enable it. Once I do that I have no trouble making network connections until the next time I reboot at which point I repeat the process. It's annoying, but manageable since I reboot very infrequently.

  • Windows Security Center Service is missing

    - by TheTub
    I am trying to fix a Windows 7 machine here that has been infected with all kinds of Malware. I have removed all of them as far as I can see but I am stumped by one last task. One little bugger managed to remove the Windows Security Center service from the list of Windows services. So I cannot start it or set to automatically start. At the moment I cannot get the Windows firewall to turn on or any anti-virus software. The security center shows the following image when I try: Does anyone know how to add this back to the list of services so I may set it to start. I don't have a backup of the registry for this computer (it's not mine). Many thanks TT

  • Streaming video from a point-and-shoot camera that doesn't support it

    - by egasimus
    I have a Canon IXUS 120is (PowerShot SD940) - a nice digital camera that's a couple of years old. It does record fairly decent video, but, alas, can't function as a webcam - and I need to stream video over the Web. I've installed CHDK on it, and while it's quite flexible, doesn't seem to provide a solution to my problem. I suppose that the video footage is written to the SD card in real time - is there a hack that allows me to monitor the file as it is written, and broadcast its contents over the Internet? Perhaps connecting its the camera's slot to my laptop's card reader via SDIO? I'm running Windows, but I'm roughly familiar with Linux; another question has suggested a file-to-/dev/video driver - do such tools exist?

    My whole drive data is lost because I installed ubuntu. After that, I formatted my Laptop and make new drives. in which, one partition is cant accessible because its a raw partition.

My problem is that I want to recover my data which is deleted because of ubuntu.. I can recover the most recent data from iCare Recovery, but i cannot recover previous data.. Please, help me for that. I am trying this from many days. Thanks

  • Is my Windows partition too far down on the disk?

    - by Trevor Alexander
    I have /boot/ on /dev/sda1 (1GB), followed by my Linux root LVM on /dev/sda2 (1.3GB). Finally, I installed Windows 7 on /dev/sda3 in the remaining 700GB of space. When I select Windows 7 in the grub menu, I get something like the following error and am thrown to grub4dos: find --set-root --ignore-floppies --ignore-cd /bootmgr Error 15: file not found Unable to locate necessary tables for adjustment. None of the options in grub4dos return anything but the above error. I heard that 1TB is the upper limit for locating Windows 7 partitions; is this true? How can I fix the above?

  • Can I put a laptop Core i7 CPU in a desktop?

    - by Weezy
    One of the most important thing to me for a CPU is a good mix between speed and heat. For example five years ago I bought a Core 2 Duo 6300 (max TDP 65W): I put a big heatsink on the CPU, no fans (I do hate moving parts and noise) and it worked like a charm and very silently for five years (and it still work but five years later I wouldn't mind a faster CPU and a faster memory controller and more memory). I consider a max TDP of 130W unacceptable (like some high-end Core i7 have), for several reasons. So I was wondering: can I build a desktop and put a Core i7 CPU meant to be used in laptop in it? For example I was thinking about the Core i7 740QM (max TDP 45W [!]). Are these compatible with desktop Core i7 motherboards? (for example on NewEgg it says that the "CPU socket type" for the Core i7 740QM is PGA988, I've not too sure about what this is)

  • Ubuntu 12.04 boot degraded raid

    - by beacon_bonanza
    I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails. I've tried to copy the MBR from disk 1 to 2: dd if=/dev/sda of=/dev/sdb bs=512 count=1 but this didn't make a difference. Any ideas how to get it to boot from just the second disk? fdisk -l Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sda1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sda2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sdb1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sdb2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00035b05 Device Boot Start End Blocks Id System /dev/sdd1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c73aa Device Boot Start End Blocks Id System /dev/sdc1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/md1: 1984.3 GB, 1984264208384 bytes 2 heads, 4 sectors/track, 484439504 cylinders, total 3875516032 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md2: 2000.3 GB, 2000263380992 bytes 2 heads, 4 sectors/track, 488345552 cylinders, total 3906764416 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md0: 16.0 GB, 15990652928 bytes 2 heads, 4 sectors/track, 3903968 cylinders, total 31231744 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000

  • Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

    - by jonathanconway
    I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?
