• How To Cancel Pending Windows 7 Updates

  - by Itai

  How To Cancel Pending Windows 7 Updates? The key is pending. The shutdown button has the windows update symbol meaning that there are updates that were selected to be installed which were download and will be installed upon shutdown. The only thing is that my machine will no longer boot if I let it install those updates! They are incompatible with a driver needed in the system and I did not found out until too late. The system admin used a recovery disk to get back to the previous restore point, only the updates are now pending, so I need to cancel those before the machine shutdowns next.

• SQL Server store procedure encrypt is safe?

  - by George2

  I am using SQL Server 2008 Enterprise on Windows Server 2003 Enterprise. I developed some store procedure for SQL Server and the machine installed with SQL Server may not be fully under my control (may be used by un-trusted 3rd party). I want to protect my store procedure T-SQL source code (i.e. not viewable by some other party) by using encrypt store procedure function provided by SQL Server. I am not sure whether encrypt store procedure is 100% safe and whether the administrator of the machine (installed with SQL Server) still have ways to view store procedure's source codes? thanks in advance, George

• How to disable 3G USB Modem internal storage from being loaded by linux kernel?

  - by Krystian

  Hi, I've got a problem with my 3G modem [Huawei E122]. It has internal storage and kernel assigns a device [/dev/sdX] to it. Because of that, every second time my machine will not boot - kernel panic - as my usb hdd gets assigned /dev/sdb instead of /dev/sda. I cannot use LABEL nor UUID in root= kernel parameter, as it is only available when using initrd, and I can't use it - I am using Debian on my router - mips architecture machine. I have to prevent this from happening, as my router has to start everyday and I have to be sure it works ok. I don't have physical access to restart it when something goes wrong. I don't use my modem internal storage, there's no SD card inserted. However kernel detects the reader and loads it. I can not prevent loading od usb drivers since my hdd is on USB as well. I will appreciate any ideas.

• Java JRE: Setting default heap size

  - by AndiDog

  I'm having trouble with Java on a virtual server, it always gives me the following error: # java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I first solved this by using the CACAO virtual machine (of OpenJDK, by putting it first in jvm.cfg), but then I run into problems with my web application (Play! framework based, gives me nasty LinkageErrors). So I cannot use that VM. Instead I'd like to just use the normal server VM and set -Xmx128M by default. How can I do that? Related: this question

• Multiple users writing to one Samba mount point in OSX

  - by Sam

  I have an OSX box containing a script which writes a unique file to a Samba share. The first part of the script mounts the share. On the machine are 2 users- UserA and UserB. Each requires to run this script at any given time however only the user who mounted the share is able to write to it. I really need both users to have rwx access. Here is what I have tried: Mounting then chmod'ing the mountpoint (no effect- overruled by Samba server?) chmod'ing the mountpoint then mounting (same as above) sudo mount_smbfs Both users have admin privileges. Ideally a solution would be executable by one of the users (contained in the script) and not rely on mounting at machine boot time. Any ideas appreciated, thanks!

• Installing VMWare Tools in Windows Server 2008 fails system startup

  - by Hoghweed

  I recently created a vmware virtual machine with windows server 2008 enterprise as Guest. My host is Ubuntu 10.04 on my Lenovo laptop. I fall into a big trouble which makes my created VM unusable after I've installed VMWare Tools. After installing tools I'm able to run the system only in safe mode. After some event manager analysis I found the issue is with drivers installed by vnmware tools. Any one has got the same issue? Is there any good practice for doing that? The configuration of vm machine is the following CPU : 1 RAM : 1020 HD : 40GB Splitted files, SCSI CD : IDE Thanks in advance

• Xen P2V for large physical hosts with much free space

  - by Sirex

  I need to P2V a rhel5 machine to xen under rhel5. I know I can use dd if=/dev/sda then using virt-install --import on the host, but the downside of this is the original machine has 80% free space on its drive. Does anyone know of (or can document) a quick and easy method which works reliably, to produce a bootable xen image which can run under a hvm in such cases ? I tried clonezilla to make the image, to avoid the free space problem, but it failed to do the clone with "something went wrong" (useless info, i know). At the moment im looking at doing a dd of each partition, and a file level copy of the partition which is mostly empty, then creating a new virtual disk, copying the partitions over to it by mounting both the new image and the virtual drive on a second vm, then copying the boot sectors over, then copying the file level backup..... there must be an easier way ? Oh, and budget is $0. :)

• How do I debug xorg/fglrx related system freezes on Ubuntu 12.10?

  - by racerror

  My brand new system is randomly freezing and I don't know how to debug the issue. System: AMD A10-5800k Asus F2A85-M motherboard Integrated Radeon HD 7660D 8gb Samsung ddr3 1600 Ubuntu 12.10 Gnome shell / Unity (issue exists in both) xorg.conf (relevant parts): Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:0:1:0" Option "TexturedVideoSync" "on" Option "UseFastTLS" "2" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "Monitor0" DefaultDepth 24 Option "UseEDID" "False" Option "ExactModeTimingsDVI" "True" Option "NoBandWidthTest" "true" Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, NoEDIDModes" Option "UseEDIDDPI" "False" Option "UseEDIDFreqs" "0" Option "NoLogo" "True" Option "Coolbits" "1" Option "metamodes" "DFP-0: 2560x1440_60 +0+0" SubSection "Display" Depth 24 Modes "2560x1440" EndSubSection I ran memtest on my ram and it checks out fine. I have tried using the latest fglrx and fglrx-beta. I have loaded 3.6.x kernel. I do not see anything relevant in dmesg, kern.log, syslog, .xsession-errors or Xorg.log. I cannot ssh into the machine when frozen from another machine. I know that system resources not being stressed when the crashes happen. It seems that video and any gaming (very simple graphics games) contribute to the freezes most frequently. However, I have experienced the crash before when just using Chrome. I suspect the crashes are xorg/fglrx related, but I have no evidence to back that up. Where should I look? What should I grep for? What should I try next?

• External TV only allows 640x480 using VGA cable

  - by EdC

  I have Ubuntu precise installed on a MacBook Pro. When connecting to an external television using a VGA style cable the highest resolution available seems to be 640x480. I'm using the proprietary NVIDEA Accelerated Graphics Driver (version current) and attempting to setup the TV using the nvidea-settings tool. I know all the equipment supports higher resolutions because of the following: Prior to rebuilding my machine with precise, the same TV, cabel & adapter gave higher resolutions The same machine & TV when used with a HDMI cable allows higher resolutions Windows laptops with the same cable & TV are able to achieve higher resolutions I'm not sure what to look for next, there are some similar FAQ questions but I'm not sufficiently familiar with the areas involved to know if these are my issue or are safe to try. Specifically: colord problem & my monitor resolution 640*480 with no other options! - is the closest, but as I'm having no problems with the main laptop monitor I'm not sure the described symptoms apply. I can't work out from the answer or Bumblebee site how to determine if nvidia optimus applies to my laptop. Why isn't my monitor's native resolution appearing as an option? - suggests configuring X by hand, but doesn't entirely match the symptoms I'm seeing

• I shrunk the Windows partition, now it says grub rescue on boot

  - by user1009013

  I have got a machine with dual-boot Windows 7 and Ubuntu 11.10, and I wanted to add another OS to that (Jolicloud), so I started the partition manager in Windows and shrunk the Windows partition by about 10 GB (so now I have:Windows;currently empty 10GB;Ubuntu). I shutted down the computer because I was finished. Now when I started my machine again it says error:no such partition. grub rescue> and I can type commands. ls gives (hd0) (hd0,msdos5) (hd0,msdos4) (hd0,msdos2) (hd0,msdos1) (fd0) if that helps

• Linux Mint on VirtualBox has no internet connection

  - by Martin

  Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

• Creating an app shortcut in Windows 7 XP Mode

  - by MT_Head

  I have a VERY old legacy app that I've managed to move from machine to machine; the installer for it doesn't actually work under newer versions of Windows, but I was able to track down the registry changes and DLL registrations necessary to make it work. I'm able to create a desktop icon in my XP mode environment, and the program works... but I'd like to add an icon to the Windows 7 menu, and run the program in semi-native mode. For example, the icon for Microsoft Security Essentials in XP mode has the following target: %SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\VMCPropertyHandler.dll,LaunchVMSal "Windows XP Mode" "||232f633" "Microsoft Security Essentials" Now, the only part of that that seems to be "magic" is "||232f633" - does anyone have any idea where that comes from, or how to identify the correct equivalent for an arbitrary program? I gather that, had the program been installed normally through a .msi file (or WISE, or NSIS, or what have you), this id would have been generated automagically... Thanks for any insights!

• How can I change the lock screen in Windows 8 that appears for the default user?

  - by Mark Allen

  This is about Windows 8 RTM. How can I change the lock screen in Windows 8 that appears after connecting to the machine via RDP? You can change your lock screen for your user account like so: Hit the Windows key. Right click your user name in the upper right hand corner, choose Change Account Picture. Click Lock Screen, choose a new picture. However, if you then connect to the computer where you've done this from another computer via RDP, using the same account, the physical machine you've connected to will display the "default" user lock screen - a stylized Space Needle / Seattle picture. It's not a bad picture, but I'd like to change it.

• Get the "source network address" in Event ID 529 audit entries on Windows XP

  - by Make it useful Keep it simple

  In windows server 2003 when an Event 529 (logon failure) occures with a logon type of 10 (remote logon), the source network IP address is recorded in the event log. On a windows XP machine, this (and some other details) are omitted. If a bot is trying a brute force over RDP (some of my XP machines are (and need to be) exposed with a public IP address), i cannot see the originating IP address so i don't know what to block (with a script i run every few minutes). The DC does not log this detail either when the logon attempt is to the client xp machine and the DC is only asked to authenticate the credentials. Any help getting this detail in the log would be appreciated.

• MMS gets hostname from uname and can't connect to it

  - by Adam Monsen

  I'm trying to get 10gen's MongoDB Monitoring Service monitoring my 3-node replica set. The replica set running in an AWS VPC. Each node runs on a different [virtual] machine. Assume their IPs are 192.168.1.1 (primary or secondary), 192.168.1.2 (primary or secondary), 192.168.1.3 (arbiter). From a quick look at the source, MMS appears to get the hostname of the machine it is running on like so: platform.uname()[1] For my VPC EC2 instance, this returns something like ip-192-168-1-1 MMS then tries to connect to this hostname, which does not resolve. I'd rather just use IP addresses (since they're always static), but it seems like the hardcoded use of platform.uname()[1] in mmsAgent.py precludes that. So, what's an elegant way out of this? Hack /etc/hosts? I'm not setting up a DNS server just for this. Maybe I'm just misunderstanding how to configure MMS.

• nmap reports host up when it isn't

  - by martianway

  On an Ubuntu VM I ran: sudo nmap -sP 192.168.0.* This returned: Starting Nmap 5.00 ( http://nmap.org ) at 2010-12-28 22:46 PST Host 192.168.0.0 is up (0.00064s latency). Host 192.168.0.1 is up (0.00078s latency). Host 192.168.0.2 is up (0.00011s latency). . . . Host 192.168.0.254 is up (0.00068s latency). Host 192.168.0.255 is up (0.00066s latency). The problem is I only have 4 live machines on 192.168.0.* so why did nmap report every ip in the subnet has a live host? The ip address of the Ubuntu machine is 192.168.28.131 From this VM I can ping the live systems on my internal subnet 192.168.0.* and get the expected response. And if I ping a machine that doesn't exist I can get no response as expected.

• How to create a VPN between a Host and VMWare VMs?

  - by Anindya Chatterjee

  I have a set of machines as follows My home laptop running Win7 Ultimate with internet connection. A vmware workstation vm running Windows Server 2003 Standard edition server in my laptop w/o internet connectivity Some of my peers' machines connected to internet I want to create a VPN with these machines, provided the VM will not have any direct internet connection and my peers should able to connect to the SVN server application running on this Win2003 server VM. Can anybody please suggest me how to setup this network, what software I need to install in both physical machine and vm, what kind of network connectivity should be there between vmware guest and host machine? EDIT: I deliberately don't want to connect the VM with internet. The host will work more of a gateway of the VPN connection for the VM.

• Install Linux with two hard drives

  - by rdecourt

  I've a machine with two hard drives. The first one has 80 GB and the second has 120 GB. I'm about to format this machine and install Linux, and I want to install all the main partitions (/, /boot, /usr/, etc.) on the first hard disk drive (sda) and mount the /home and /var partition on second disk (sdb). Is this possible, and do I have to do something after the instalation? Or is the second hard disk drive automatically mounted? How can I do it? I won't do it, but is there any problem to mount /boot on the second hard disk drive? I'm using Ubuntu 12.04.

• How can I disrupt my roommate's BitTorrent?

  - by bob

  We're on a 50 mb/s Comcast connection and our connection right now is coming in under 1.5 mb/s. Our roommate left for a week with BitTorrent running (Azureus client, we think). Our latency is approaching 300 ms. His door is locked up tight, and both his machine and the router for the house are located inside. I've even flipped the power breaker in the house and that barely works for 2 minutes. His laptop keeps on running, and once the cable modem and router come back up and the machine reconnects, the torrents resume in earnest. I've been running nmap and identified his IP on our LAN. Is there anything I can do over the LAN to make his torrents start to fail or slow down?

• Remote access to a KVM Ubuntu virtual server

  - by Lee

  I've just setup an ubuntu virtual server and everything seems to be working fine. I used KVM to get it working with a bridged network. I've given the virtual server a static ip address on my network. I don't seem to be able to connect to the virtual machine though from outside my network. If I'm on my own network it all works fine, I can ping the ip and connect to it. The virtual server can ping other machines and sites on the internet. I changed the port forwarding rules on my router to forward any connections on a specific port to the virtual server ip address thinking that was the problem, but it was still the same. Is there something I'm missing here which is blocking outside connections to the virtual machine? Thanks.

• Blank screen after grub menu

  - by Tim

  I just rebooted an Ubuntu Server 10.04. After choosing boot options in the grub menu, though, it just displays a black screen with the blinking white underscore in the upper-left corner. The machine has had (hardware) trouble with networking before, but the problem remains after 10 minutes, so I don't think it's the problem now. Booting into recovery mode or using earlier kernels yields the same problem. This also happens if I boot from another hard-drive. I haven't yet tried to boot from CD as the machine lacks a CD reader. How should I diagnose the problem? Update: My boot options are: recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 567[redacted] linux /boot/vmlinuz-2.6.32-29-generic root=UUID=567[redacted] ro quiet splash initrd /boot/initrd.img-2.6.32-29-generic Update: Also, I cannot access the virtual terminals (ctrl+alt+Fn).

• Can ping/nmap server, nothing else

  - by lowgain

  I was SSHed into our ubuntu LAMP server , and was just doing a svn update, which hung. I disconnected, and since then, I have not been able to SSH in or view any of our websites (neither from my network or through a remote machine). I would have just assumed the server went down, but I can ping the machine and get really quick responses. Using nmap on the box shows all the normal ports open, so I am confused This server is hosted remotely in a datacenter, do I have any remaining options except contacting them for support? Thanks!

• 32bit ODBC Postgres driver on Windows 2008 R2 x64

  - by uaise

  I'm trying to install the Postgres ODBC 32bit driver on a Windows 2008 R2 64bit machine. After installing it, with no errors, I go to the ODBC panel, the 32bit version under the /syswow64 folder and try to add the driver, select the Postgres driver from the list but I get an error 126, saying he can't find the driver at the specified path. The problem is that the path he shows me, is the exact path the driver is in, I double checked on the registery (on the HKLM\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI\ location) and it's fine there too. A couple more people on technet have the same issue too. Did anyone ever run into this? Any ideas would be greatly appreciated. edit: the driver works fine on my win7 x64 test machine, this behaviour only happens on the server.
