• Windows 7 DHCP Default Gateway not Overridden by manual Default Gateway

  - by dgwilson

  We have recently installed Windows 7 for student computers. All student computers must be routed through our content filter which is located at 192.168.0.63. This was done in WinXP by adding a Default Gateway in the network adapter settings TCP/IP Properties Advanced Default Gateway. All teacher computers are routed through the DHCP assigned Default Gateway of 192.168.0.1. In WinXP the dhcp default gateway was correctly overridden by this manual setting. In Win7 it appears that the dhcp default gateway is retained and the manual one is added to the list so that there are two with the dhcp one having the primary metric. I have tried several ways to remove the dhcp default gateway such as, running the "route delete 0.0.0.0 192.168.0.1" command. Doing this from an administrator command prompt works but it just resets upon reboot. I've tried adding this command to the registry's Run section but it seems to run as a non-administrator and therefore will not complete successfully. Is there any way to prevent this and force the manual default gateway to override the dhcp one? Or to remove the dhcp assigned one automatically on boot/login? HELP! We CANNOT allow student computers to connect to the internet without going through the content filter.

• Adding network share as the system account breaks Win7 backup to network

  - by ChrisBenn

  (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

• Linux: Force fsck of a read-only mounted filesystem?

  - by Timothy Miller

  I'm developing for a headless embedded appliance, running CentOS 6.2. The user can connect a keyboard, but not a monitor, and a serial console would require opening the case, something we don't want the user to have to do. This all pretty much obviates the possibility of using a recovery USB drive to boot from, unless all it does is blindly reimage the harddrive. I would like to provide some recovery facilities, and I have written a tool that comes up on /dev/tty1 in place of getty to provide these functions. One such function is fsck. I have found out how to remount the root and other file systems read-only. Now that they are read-only, it should be safe to fsck them and then reboot. Unfortunately, fsck complains to me that the filesystems are mounted and refuses to do anything. How can I force fsck to run on a read-only mounted partition? Based on my research, this is going to have to be something obscure. "-f" just means to force repair of a clean (but unmounted) partition. I need to repair a clean or unclean mounted partition. From what I read, this is something "only experts" should do, but no one has bothered to explain how the experts do it. I'm hoping someone can reveal this to me. BTW, I've noticed that e2fsck 1.42.4 on Gentoo will let you fsck a mounted partition, even mounted read-write, but it seems only to do so if fsck is run from a terminal, so it can ask the user if they're sure they want to do something so dangerous. I'm not sure if the CentOS version does the same thing, but it appears that fsck CAN repair a mounted partition, but it flatly refuses to when not run from a terminal. One last-resort option is for me to compile my own hacked fsck. But I'm afraid I'll mess it up in some unexpected way. Thanks! Note: Originally posted here.

• Microsoft Security Essentials & MsMpEng.exe hogging resources

  - by Mike

  I've been using MSE for a couple months now, never had a single problem. All of a sudden the process "MsMpEng.exe" will randomly go crazy and hog all my system resources so I can't do anything unless I kill it in the task manager. (I've quit the program for now and my comp is running smooth). When I restart the program, reboot, whatever, it goes off and hogs all the resources again after a couple minutes. If I kill the process it will go away and then come back a couple minutes later and do the same thing. I've scanned with MSE, another antivirus and malware with no probs. Any ideas? Should I uninstall and find something else? The thing is I've liked it so far. I'm running Win7 64-bit. Also, I'm not running any other conflicting security programs. This is the only one on my PC right now. Windows Defender is also off.

• Package upgrade on Ubuntu raid server and grub setup issue

  - by RecNes

  I have remote Ubuntu 10.10 server running on raid system. I did package upgrade yesterday night for security reasons. During the upgrade, grub installation screen appeared and asked me which partition I wanted to install grub. Options are sda,sdb,md1 and md2. I decide to install them on both sda and sdb partitions. I wondering, was I make true decision? If machine get reboot is it can be boot up safely?

• Communicating via Command Mode with IBM HS22 IMM via AMM

  - by MikeyB

  On previous model blades that contained a BMC, I was able to communicate from our external management station via pass-through commands to the BMC to do things such as power blades on/off, set VPD parameters, reboot the BMC, etc. Now on the HS22, a bunch of things happen differently. For example, we can no longer use the same pass-through commands to write VPD information pages and have them persist across reboots of the IMM - it looks as though those VPD pages are populated from information contained in the IMM. How do we use the Advanced Settings Utility from an external host to communicate with HS22 IMMs? Alternatively, what TCP Command Mode commands do we need to send to the AMM to communicate with the IMM? For our purposes, we specifically cannot communicate with the IMM from the blade itself. Specific example: When I send a pass-thru IPMI command via the AMM to the blade BMC to write information (such as MTM, Serial) into VPD page 0x10, it persists on blades with a BMC (HS21 for example). I can send the same IPMI command to write data to the VPD page on the HS22, however it does not persist across reboots of the IMM. What IPMI commands do I need to send to the IMM? What IPMI commands are asu sending when it sets the MTM & Serial?

• Setup of high-end web server and DB server cluster on Amazon EC2: Is this how it's done?

  - by user1086584

  Amazon is so technical, I want to confirm that my understanding is correct. We have a large 500 GB database. (OrientDB.) We will have it mirrored to one another in the same Availability Zone. We believe the database size will grow rapidly. The plan is: Get 4 large instances that are compatible types with Placement Groups (as well as ideally, Enhanced Networking) (2 for web, 2 for DB.) We use an EBS-backed instances to store our operating system. Discussion here: http://alestic.com/2012/01/ec2-ebs-boot-recommended We can set up ephemeral SSD instance storage as swap space. (But it is lost after even a reboot. I hear its hard to add ephemeral storage if booting from EBS, but possible.) For offsite backup, we will take periodic snapshots and store them on S3. Obviously we need to ensure the database is in a safe state when that snapshot happens to avoid corruption. (Any hints here, aside from shutting down the DB?) If the database gets too big, we need to create a EBS volume that's larger. We can use RAID to break the 1 TB limit: http://alestic.com/2009/06/ec2-ebs-raid Static assets on web servers will be stored on S3. Is that correct? Or am I missing something?

• Safe mode boot with no change on screen but ongoing hard disk activity - why?

  - by omatai

  I have a machine with a dying hard drive - bad sectors are starting to multiply :-( The first sign (24 hours ago) was that it had an unmountable boot volume. At this time, I tried booting to safe mode with command prompt, which worked, after which I rebooted normally and ran a chkdsk. It has since been working as well as I could expect, but slowly getting less reliable. So I scheduled another chkdsk on both partitions (C: - boot, D: - data), having freed up a lot of space on both partitions to give Windows a little more scope for repairs (hopefully?). I then rebooted. On reboot, it protested about the unmountable boot volume again, so I booted to safe mode. I got the same list of drivers loaded as yesterday, and then no change to the screen for the past 2 hours. However, I see a flickering hard drive indicator light - not always on, but seldom ever off. What is happening? Is the chkdsk that runs in safe mode one which produces nothing on the screen and so chkdsk could be doing its thing... or is Windows still trying (but failing) to boot into Safe Mode?

• Redundant Microsoft server solution for small company

  - by MadBoy

  I'm planning to change one server Microsoft SBS 2003 with SharePoint, Exchange and SQL database into something that will provide me with some redundancy and won't be single point of failure. I was thinking to buy 2x exactly the same physical servers and put 2 virtualized servers on HyperV or VMWare on each. Then i would put SharePoint, Exchange and SQL on that 1 physical server (shared onto 2x VM's). I would like 2nd physical server to be exact duplicate of the first one so that when 1st server goes down (for reboot or hw failure), 2nd takes care of everything so that users don't even see anything changed (in terms all their emails, sharepoint stuff is available). My questions are: Will I have to pay for licenses for both servers even thou only one instance of SharePoint, Exchange, SQL will be used at same time? What are proposed solutions to do that? Any additional hardware I would need, any complicated software configuration to be expected to configure such redundancy so that when one physical server goes down 2nd one is taking care of rest? What problems should I expect? This solution is for 60 people. Later on it may or may expand.

• Accidentally deleting all OSX users using dscl

  - by gutch

  OK, so I just did something really stupid and deleted all the user accounts on an OSX 10.6.6 machine by running this: sudo dscl . -delete /users What I actually wanted to do was delete a single, troublesome account using a command like this: sudo dscl . -delete /users/localadmin ...but I absent-mindedly pressed return too early and deleted the lot. I've tried using -list and can confirm that I have indeed wiped all the accounts. The machine is currently running fine, but I'm sure that once I log out / reboot then it will be completely broken. I don't mind that I've deleted the normal user accounts (there was only one I wanted anyway). But it's surely going to be a big problem that system accounts like _installer and _jabber and _lda and _windowserver etc etc are gone. So my question is, how can I restore the standard set of system accounts? Do I have to reinstall OSX from scratch? Or can I either: undelete those system accounts, or run some command to recreate the system accounts?

• Fixing corrupt files or corrupt file table on a USB drive?

  - by Kelsey

  I was doing a virus scan on an external USB drive while copying data over to it. While AVG was scanning my system got locked up I think due to the USB drive running out of space and it required a reboot. Since that time all data on the external drive is no longer accessible. I can see all the files in the root and directories but I cannot browse into any of them as Windows 7 gives an error stating they are corrupt. I think the file table or whatever it uses to store the index of what exists on the drive has been corrupted since it still shows the the drive as being almost full but everything I do a properties check on says it is 0 bytes. Does anyone know how to 'unlock' or recover this data? Is there a way to rebuild the file table somehow? Luckily I can recover this data from other sources as a last resort but I would like to fix this if possible. Any help would be appreciated. Thanks.

• Umount stale glusterfs partition

  - by Khaled

  I am using glusterfs on several Ubuntu servers: two of them are running glusterfs servers in replication mode. Without any clear error, the glusterfs partition became stale and the system shows this error when I try to access the stale partition: Transport endpoint is not connected Also, when running ls -l on the parent folder I get: d????????? ? ? ? ? ? myfolder I tried all types of commands that I can find to umount this partition, but I could not get it done: umount -l /path/to/mount/point umount -f /path/to/mount/point Also, using fuser command to show processes accessing this folder did not work. Unload the fuse kernel module can not be done as it is clear from the kernel config that fuse is built into the kernel and not a loadable module. I found this line in /boot/config-2.6.32-24-server CONFIG_FUSE_FS=y I have been left with two options: Reboot the system. Create another mount point like myfolder2 and mount this again using sudo glusterfs -f /etc/glustefs/glusterfs.vol /path/to/folder2. Of course, I have chosen to go with option 2. Anyone faced such an issue before? Anyone has a better solution for such a case?

• Why Is Web Sharing Broken on My Mac?

  - by Sam Murray-Sutton

  Background: I use my Mac for web development, running copies of web sites locally. I recently installed the Snow Leopard update, which to all intents and purposes seems to have gone fine, except... What's not working? Web-sharing; more specifically I can't turn it on via preferences. The preference pane just hangs when I try to. So Apache doesn't start on reboot. I can start Apache by hand, but I don't know enough to either setup apache to start with the computer, or to properly fix web sharing. Further details My Apache error log shows nothing on when the system boots up (as I would expect). This is the error message when I try to start web sharing from the sharing preference pane. 28/09/2009 10:58:05 System Preferences[834] setInetDServiceEnabled failed with 1 for org.apache.httpd Here's the messages given when I start apache from the command line.

Any help would be greatly appreciated. UPDATE I have added an answer of my own below - I was able to solve it thanks to being pointed in the right direction by the comments below, so thanks very much. But I'm still not totally clear as to what caused the problem or how my solution addressed it, so I'm leaving the question open for now.

• Give back full control to a user on a disk from another computer

  - by Foghorn

  I have my friend's hard drive mounted externally. After messing with the permissions with TAKEOWN so I could fix some viruses, I have full control over their drive. The problem is, now it's stuck in a "autochk not found" reboot sequence. I think the problem is that the boot sector is invisible to the drive now. So my question is, How can I use icacls to give back the full ownership, when the user I am giving it to is not on my machine? I ran the TAKEOWN command from my windows 7 laptop, their machine is a windows xp Professional with three partitions, I only altered the one that has the boot sector. Here is the permissions that icacls shows: (Where my computer is %System% my username is ME, and the drive is E:\ C:\Users\ME icacls E:\* E:\$RECYCLE.BIN %System%\ME:(OI)(CI)(F) Mandatory Label\Low Mandatory Level:(OI)(CI)(IO)(NW) E:\ALLDATAW %System%\ME:(I)(OI)(CI)(F) E:\alrt_200.data %System%\ME:(OI)(CI)(F) E:\AUTOEXEC.BAT %System%\ME:(OI)(CI)(F) E:\AZ Commercial %System%\ME:(I)(OI)(CI)(F) E:\boot.ini %System%\ME:(OI)(CI)(F) E:\Config.Msi %System%\ME:(I)(OI)(CI)(F) E:\CONFIG.SYS %System%\ME:(OI)(CI)(F) E:\Documents and Settings %System%\ME:(I)(OI)(CI)(F) E:\IO.SYS %System%\ME:(OI)(CI)(F) E:\Mitchell1 %System%\ME:(I)(OI)(CI)(F) E:\MSDOS.SYS %System%\ME:(OI)(CI)(F) E:\MSOCache %System%\ME:(I)(OI)(CI)(F) E:\NTDClient.log %System%\ME:(OI)(CI)(F) E:\NTDETECT.COM %System%\ME:(OI)(CI)(F) E:\ntldr %System%\ME:(OI)(CI)(F) E:\pagefile.sys %System%\ME:(OI)(CI)(F) E:\Program Files %System%\ME:(I)(OI)(CI)(F) E:\RECYCLER %System%\ME:(I)(OI)(CI)(F) E:\RHDSetup.log %System%\ME:(OI)(CI)(F) E:\System Volume Information %System%\ME:(I)(OI)(CI)(F) E:\WINDOWS %System%\ME:(I)(OI)(CI)(F) Successfully processed 22 files; Failed processing 0 files C:\Users\ME

• Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

  - by knda

  I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly.

• On dual boot system, Is it possible to use VirtualBox to boot other installed OS?

  - by Derek Ziemba

  I currently run Windows 7 from a 256GB SSD as my Operating System. Lately, for school, I've been using openSUSE linux inside a VirtualBox PC and I'm really liking it. I'm starting to hate even working in Windows. But I can't just abandon Windows. I've been considering dual booting openSUSE and will likely purchase another SSD for openSUSE. Once I have the dual boot set-up, there is going to be times I need to do something quick in the operating system that I'm not currently in. It would be a pain to have to reboot the computer each time I need to switch the OS for a simple task, especially from Windows since it doesn't let you save it's state. From openSUSE, I want to be able to start a VirtualBox Machine using my Windows Drive. And in Windows, I want to be able to start a VirtualBox Machine of my openSUSE Drive. Would this be possible? The issue I'm worried about is drivers. For instance, the OS will be installed on native hardware and have the native hardware's drivers configured. When I try to boot the OS in a VirtualMachine, I feel like the OS is not going to know what to do, and have to reconfigure itself or just not work.

• Ubuntu 10.04 Keyboard and Mouse Freezing Problem

  - by nitbuntu

  I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

• Error loading operating system: format Windows 7 to Windows XP Service Pack 3

  - by Blerta

  I saw that there are other questions like mine here. But O also saw that some problems where solved with fixmbr from a Windows 7 recovery console, but that didn't work for me. I bought my laptop with Vista installed and later reformated and used Windows 7. During formatting with Windows 7 I had some problems with my hard drive and found out it was dead so I bought a new one. I wanted to reformat with Windows XP,because Windows 7 is consuming more RAM that it is able handle and I wanted to use it for other programs. So I formatted with Windows XP Service Pack 3 but after first reboot a message appeared: "Error loading operating system" Reading here, I assumed that maybe I had installed it on the wrong partition and maybe having two OS now, so I used fixmbr but it is still not starting up. Anyway I am sure that is not the case of two operating systems. Is there any chance that when the computer designed to work with Vista you would face problems with Windows XP? Like not recognizing a hard drive?

• Upgrade Debian to unstable on VirtualBox: udev problem

  - by Ken

  I'm running Debian stable on VirtualBox on Windows Vista 64-bit Ultimate. It's been running great, but I needed some newer packages, so I put sid in my sources.list to upgrade to unstable (as I've done a dozen times on various Linux boxes over the years). When I upgraded, something went screwy and it asked me to run apt-get -f install to fix them, which gave this: (Reading database ... 77846 files and directories currently installed.) Preparing to replace udev 0.125-7+lenny3 (using .../archives/udev_151-3_amd64.deb) ... Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED feature is disabled in the running kernel. Please upgrade your kernel before or while upgrading udev. AT YOUR OWN RISK, you can force the installation of this version of udev WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file. There is always a safer way to upgrade, do not try this unless you understand what you are doing! dpkg: error processing /var/cache/apt/archives/udev_151-3_amd64.deb (--unpack): subprocess new pre-installation script returned error exit status 1 insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). Errors were encountered while processing: /var/cache/apt/archives/udev_151-3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I have the VirtualBox extensions installed, and it looks like the udev install doesn't know what to make of them. But I don't know exactly where/how they're installed (I just ran the VBoxLinuxAdditions-amd64.run script, basically), so I don't know how to disable them. Any ideas? Thanks!

• How to "swap in" again memory from page file to physical memory in Windows at once (like linux swap-off)

  - by Arnout

  Is there a way to swap back in (to put back all the memory data that was put into the page file (or swap, whatever you prefer)) memory on a windows PC? On linux, one can easily do this with the swapoff /dev/sdaX, where X is the swap partition. On windows, it seems to ask me to reboot each time.. The reason I'd like to do this, is that, even though swapping out the data to the swap file allows me to play a resource-hungry game fully in physical ram, when I stop the game, all the rest of my programs run slow. This is or course normal; all the programs were pushed into the page file because my RAM was too small, and all memory access to those programs after gaming bumps into hard page faults, with major delays and some frustration as a consequence. However, that frustration could easily be avoided, by simply allowing the PC to copy all data back into the physical memory for a minute or so, and then resume working on a fast working PC! (rather than having to endure the slowness -while- working) Thanks in advance for any advice on this! Kind regards

• Acronis Disk Director AFTER Clone Disk error: PXE-E61: Media test failure, check cable

  - by Kairan

  Used Acronis Disk Director on my desktop, plugged in the laptop drive 240GB SSD (USB) and the new hard drive 500GB SSD (usb) and the copy seemed to be fine. I didnt see any error messages but I didnt stare at it for 3 hours either. The clone disk of course the Toshiba hidden restore partition, the primary partition C drive and the active (boot?) partition and yes, did check box for copy NT signature. The computer boots up fine most of the time, but it seems that when the computer goes to sleep (i believe its sleep, hard to do much testing during school) or hibernate or reboot it will sometimes display this message: Intel(R) Boot Agent GE v1.3.52 Copyright (C) 1997-2010, Intel Corporation PXE-E61: Media test failure, check cable PXE-M0F: Exiting Intel Boot Agent Insert system disk in drive. Press any key when ready... Of course any key does nothing but repeat a similar method. However, if I press the power button on the laptop (Toshiba Portege R705, Win 7 Pro 64-bit) it puts computer into hibernate. After hibernating I press power button again and it comes out of hibernation without any odd messages or problems described above... so apparently that is my TEMP fix. Another recent issue I noticed is on occasion when creating a new folder or modifying something in the system variables, other random areas I will get a message: "The Stub received bad data" and simply retry the task and it works. Perhaps these two issues are linked.
