• No Cure for a Slow Computer?

  - by Marv

  I have a laptop with the following specs: 2.2gHz dual-core processor. 4gb of DDR2 Ram. 180gb HDD space. I have tried everything. I have reinstalled the OS. Installed Ubuntu with Lubuntu, LXDE, Gnome Classic, Unity 2D desktop. I have even tried downgrading to XP with all non-critical processes and services turned off. Even with the most stripped down version of Ubuntu it heats up and the fan starts churning. I'm out of ideas. I have tried everything. If you have any tips, please help. :'(

• Getting the keyboard working on a MacBook under Windows XP x64

  - by Theran

  Despite Windows XP Professional x64's unsupported status on MacBooks (model A1181), I've managed to get most of the hardware working by manually installing either the drivers on the OS X Snow Leopard CD, or finding the appropriate drivers online. However, even after installing the Apple keyboard driver from the CD, I can't get Windows to actually use the special driver. Instead, the keyboard just shows up as a generic USB keyboard, with non-functioning Fn and other special keys. Being unable to generate a right-click or Ctrl-Alt-Del makes Windows a bit of a challenge to use. I've tried: uninstalling and reinstalling the keyboard driver removing the keyboard under device manager and letting Windows re-detect it using device manager to manually update the driver How do I get the special functions of the MacBook keyboard working under XP x64?

• difference between success and failed event in auditd/aureport

  - by user112358132134

  The aureport command has two options that limit the list of displayed events to those that were successful and those that failed. Per the man page: --failed Only select failed events for processing in the reports. The default is both success and failed events. --success Only select successful events for processing in the reports. The default is both success and failed events. What does this mean? Is the failure/success with regard to the actual event (e.g., a syscall that returned non-zero) or does the failure/success apply to auditd and whether or not there was an issue in processing the event?

• Using Excel Lookup Function and Handling Case Where No Matches Exist

  - by Dave

  I'm using Excel to enter data for an event where people register. A high percentage of the registrants will have registered for previous events, so we can their name and ID number. I'm trying to use the LOOKUP function in Excel to lookup the name and then populate the ID field with their ID number. This works well unless the value that is looked up is a new user that we don't already have details for. However, if the LOOKUP function can not find an exact match, it chooses the largest value in the lookup_range that is less than or equal to the value. This causes a problem since you can't tell if the match was exact (and the data is correct) or not exact and the match is incorrect. How do I catch non-matches and handle separately?

• Moving a File While It's In Use -- How Does it work?

  - by Zaz

  I've noticed that on non-windows OS.... ie linux/mac i can do things like: - Send a zip to a friend over aim - Delete the file while it's in transfer And the transfer does not fail. Or, I can do operations like.. - start a movie - erase the file - the movie still plays to completion (read from disk, not just buffered in memory) Although the files are being "deleted", as i mentioned, they are actually being moved to a different location on the file system... ie a Trash directory or something. So it seems to me like the OS uses a pointer @ the file that is updated when it moves rather than accessing the files directly. Can anyone shed some light on how this AWESOME capability is actually implemented? I'm not even sure what to google to learn more about it. thank you.

• How can I boot a vm on Hyper-V 2012 when it has a virtual hard-drive missing?

  - by Zone12

  We have a Hyper-V 2012 server with 8 VM's on. We have attached extra virtual hard-drives to each of the computers to store backups on. These drives are stored on a NAS. After a power failure, we tried to boot the VM's and found that they couldn't be booted without the attached backup drives. We couldn't boot the NAS at that point and so we had to remove all the extra drives manually, boot the VM's and re-attach the drives at a later date when we got the NAS back up and running. These backup drives are non-essential to the running of the system. I would like to know if there is a way to boot a VM on Hyper-V 2012 with some of the hard-drives (scsi) missing so that we can recover automatically from a power failure.

• Excluding four IP's from a /32 static route

  - by Justin

  I have a Cisco ASA routing a /32 of public addresses (non RFC-1812) through a private link. When the device sees the destination address it selects the private route instead of going out over the public network. This works great but I am now trying to exclude 4 IP's from the private route. Traffic to these addresses should go over the public internet instead of being routed over the private network. Can I just add anothe route for these four IP's or do I have to modify the existing route for the /32?

• Solaris NFS: user permissions

  - by cjavapro

  I am very new to NFS. I would like to make sure I am clear. If the NFS server shares a directory rw,, and all the files in the directory are permissions 700 and user/group for those files is root/root,,, On the client you would have to log in as root to see it. Is this correct? I am aware that a non root user on the client could make a direct connection to override this. (as in don't use the mount, just use an NFS client hack.) It really seems like anyone who has access to the client machine should have access to the files and that the client machine should be ignoring permissions. Only the server should handle permissions. Am I correct in my understanding? Is it normal to have this type of layout? Is there a way to ignore the permissions on the client side?

• Windows/global setting to allow only SSL when on public Wifi?

  - by hungry

  Rather than going through each of my apps and modifying settings, or tweaking individual browser settings (I use three different browsers) or just being careful not to type non-SSL URLs into the web address bar, is there a solution at the Windows level that will prevent anything from connecting to the web from my laptop unless it's using SSL? I also have mini apps installed like Gmail checker, etc that connect to the web of their own volition using my usernames, passwords and such, so it goes beyond just web browsers. The reason I'm asking is I want to work securely on the general Internet when on public Wifi (e.g. coffee shops) without a lot of hassle or having to remember everything that needs to be locked down. When I'm back home I want to go back to full access mode using any kind of protocol on the web. If a website doesn't support SSL when I'm out in public then I just don't surf it - that's not a worry to me.

• How do I prevent users from entering a blank value in an Excel sheet?

  - by Tola Odejayi

  I want to restrict users to entering either just 0 or 1 in an Excel 2007 sheet. I use the Data Data Validation dialog to do this, but I'm finding that it doesn't stop them from entering blanks. What I would like is for there to be a prompt when they enter blanks, just like the one that appears when they enter any other non-blank data that is not 0 or 1. I plan to fill the sheet with 0s before applying the validation, so there should not be a problem with erroneous data. Also, I'm open to using VBA to fix this problem.

• How to prefer ipv6 over ipv4 only for specific websites?

  - by kria

  I only have ipv6 connectivity via a HE tunnel on my router, so normally I want to prefer ipv4 over ipv6. For some websites however, I would like to prefer ipv6. Right now I have just set DisabledComponents to 0x20 and hard coded the ipv6 resolution into my hosts file for the sites i want to access over ipv6. Since these ip addresses change at times, this is not a good solution. Any ideas on how to handle this in a non-clunky way? Some kind of Chrome/Firefox add-on might do the trick, but I couldn't find one for this purpose.

• Linux Permissions

  - by Tres

  I am running Fedora 12 and I've setup a partition separate from my root partition to keep shared files and home directories. Now, I've been having permission issues where it says the user cannot chdir into their home directory (/files/home/*). Now, I fixed this originally by chmodding / to 0755 and the home directories also to 0755. And yes, the user is the owner:group of their home directory. Now get this, I didn't change a thing, rebooted, everything still works. Great, right? I boot the server up a day later, and now same ol issue. This is a home server that wasn't on at all at any point in between the working state and non-working state. Also, nothing else was modified. Any ideas? Thanks!

• Tricking Linux apps about current time with environment variables

  - by geek

  Sometimes it is possible to trick a Linux app by calling it like this: HOME=/tmp/foo myapp This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~. A similar trick can be done like this: LANG=foo LC_ALL=bar myapp This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile. Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.

• HAproxy to web host sub directory?

  - by daemonza

  Hi for reasons outside my control, I need to load balance two servers, that run a non-virtual host enabled app on IIS. Normally in HAProxy I would load balance servers(apache, tomcat, etc) like this : acl is_www_example_com hdr_end(host) -i www.example.com use_backend www_example_com if is_www_example_com backend www_example_com balance roundrobin cookie SERVERID insert nocache indirect option httpchk HEAD / HTTP/1.0 option httpclose option forwardfor server node1 192.168.1.1:80 cookie node1 server node1 192.168.1.2:80 cookie node1 Which will route to the node 1 and node 2 server and serve up the virtual host site. if I need to route to www.example.com/application/data How would I be able to do it, with the above example, if at all even possible?

• Hyper-V R2: Need help with disk structure

  - by MojoDK

  Hi all, I'm going to use the free (non gui) version of Hyper-V R2. In my new server I have 8 disks in total (for Hyper-V R2 installation and virtual machine). Atm I'm going to run a single virtual machine, with following tasks: Windows Server 2008 R2 x64 File/Print SQL Server My question is ... with my 8 disks in the server, which disks should contain wich data? Should I install "Hyper-V R2" and VM's drive c on same physical disks? Should I use raid 1 or 5? With the above tasks, how would you structure the disks? Hope you know what I mean (I'm not english, so it's difficult to explain). Thanks!!! Mojo

• Windows 7: How to stop/start service from commandline (like services.msc does it)?

  - by john

  I have developed a program in Java that uses on a local SQL Server instance to store its data. On some installations the SQL Server instance is not running sometimes. Users can fix this problem by manually starting the SQL Server instance (via services.msc). I am thinking about automating this task: the software would check if the database server is reachable, if not try to (re)start it. The problem is that on the same user account the Services can be stopped /started via services.msc (without any UAC prompt), but not via (non-elevated) command line. The operating system seems to treat services.msc differently: c:\>sc start mssql$db1 [SC] StartService: OpenService FEHLER 5: Zugriff verweigert (Access denied) c:\>net start mssql$db1 Systemfehler 5 aufgetreten. Zugriff verweigert (Access denied) So the question is: how can I stop/start the service from a java-program/command line without having my users to use services.msc (preferrably via on-board-tools)

• Third monitor randomly defaults to 640 x 480 on startup

  - by ajbdev

  I purchased a PowerColor HD 5770 video card so I could get a third monitor working. I have two widescreen monitors, one attached via HDMI and the other attached via DVI. My third monitor is attached from DisplayPort to VGA (using a passive connector like this one) The third monitor is a 19" Hyundai L90D. I was unable to find any Windows 7 (or Vista for that matter) drivers for the monitor, so it's stuck with "Generic Non-PNP Monitor". It's native resolution is 1280 x 1024. Randomly Windows will boot up in the correct native res, but sometimes it boots up in 640 x 480 res. When it does boot up into 640 x 480 res, the screen resolution slider is stuck and I cannot slide it back to 1280 x 1024. I cannot find a pattern for when or why it will do this, I've tried rebooting five or six times in a row at times to get it to boot into native res, but this doesn't always work.

  I have been asked to help a small non profit organasation with some IT problems. They currently have a mailing list of around 200 people saved on a mac inside adres book.

I know that there are programs that can be used to send email to a larger number of people however these usually require a database and I'm not sure how to use those. Anybody got any tips?

• cygwin: ~ != $HOME

  - by user443854

  When I start cygwin, my ~ dir is the same as $HOME. After some time, ~ dir changs, while $HOME stays the same. I am puzzled by this, not sure where to look. Maybe someone experienced this, or has some clue what's going on? When I start: winuser@mybox ~ $ echo $HOME /cygdrive/c/cyguser winuser@mybox ~ $ echo ~ /cygdrive/c/cyguser Later, ~ changes to /cygdrive/c/winuser, which is non-existent. When I restart cygwin, everything is back to normal. What could be causing this?

• Windows XP clients do not update server 2008 DNS forward lookup zone.

  - by whatsisname

  I have a Cisco 5505 working as a DHCP server, and a server 2008 DNS server running an AD domain. I am having problems with all XP computers not updating the forward lookup zone. The reverse lookup zone updates are working. Windows vista and 7 computers update just fine. Additionally the DNS server accepts both secure and non-secure updates. When people are connected through the Cisco's VPN, they cannot resolve to any machines that have reverse lookup zones, but they can resolve entries in the forward lookup zone. I have tried ipconfig /registerdns, but the forward lookup zone entries for the XP clients are not being populated. How can I get the XP Dynamic DNS client to make the updates, or what can I do to debug what's going on? Thanks

• Best Practice for upgrading PHP On Production Systems

  - by Demic

  We Have two load balanced web servers running php 5.3. I've been asked by our dev team to upgrade php to 5.4 because they need certain functionality it will bring. The main issue is that 5.3 is the latest thats been built into the distros repository, so to upgrade using the package manager, Ill need to add another 3rd party repo. I dont have a problem with this per se, but Im concerned about using a package from a "non official" source. The other option is to compile php from source, but I guess this will prevent me from using the package manager to upgrade at any stage in the future? So I guess Im just looking for some guidance on which way to go. Compile from source or install from any old repo that purports to supply php 5.4? Or perhaps theres a third option I havent considered? Thanks in advance Demic

• how to recover data from my disk - I accidentally copied with dd an iso on it

  - by sijoune

  I wanted to create a bootable usb from an iso image and i accidentally put as the output of the dd, instead of my usb drive, one of my hard disks. The iso was 3,3 GB and my disk is 1TB! And it was almost full. Can i at least restore the data that has not been overwritten? Right now i can't even mount it. I get this error: Error mounting /dev/sdd1 at /media/main/UDF Volume: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sdd1" "/media/main/UDF Volume"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdd1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Also since i know which filesystem my disk used if i reformat it to this filesystem is there any chance i can mount it and retrieve the rest of the files?

• How can I forward Mailer Daemon notifications in Outlook 2000?

  - by Elvith

  I have a rule in Outlook 2000 which states that any incoming message should be forwarded to another adress (The mailaccount is only used to send automatic alerts and notifications of an application, answers to this adress should be forwarded to the admin of this application). When the application tries to send an eMail to a non existent adress, the resulting Mailer Daemon notification won't be forwarded and the admin of the server will notice this problem very late (if ever). Is there a way to forward such messages to another adress? The problem seems to be, that Exchange delivers such notifications as "Report" but the rules will only apply to "Messages". Thanks in advance!
