Raids and LVM  are very vital to a Linux server, but then again it’s one hell of a complex step recovering data from a crashed linux system. In this tutorial, I’ll try to help you recover your data on a RAID partition.

But first, let me discuss the tool I’ll be using, for this tutorial, I will use SystemRescueCD, a gentoo-based system recovery distro which for me is the far easiest tool in recovering crashed system. So back to our topic, here’s how:

1. After a clean boot on your SystemRescueCD liveCD, create your /etc/mdadm.conf

mdadm --examine --scan /dev/sda1 >> /etc/mdadm/mdadm.conf

2. Check your /etc/mdadm/mdadm.conf , it must contains something like this:

ARRAY /dev/md0 level=raid1 num-devices=2 UUID=a28090aa:6893be8b:c4024dfc:29cdb07a

3. On the last part of that line, add the following:

ARRAY /dev/md0 level=raid1 num-devices=2 UUID=a28090aa:6893be8b:c4024dfc:29cdb07a devices=/dev/sda1,missing

The string /dev/sda1 is the hardware device and missing means that the second disk in this RAID array is not present at the moment.

4. Now, start your raid setup

/etc/init.d/mdadm start
/etc/init.d/mdadm-raid start
 

5. Check if the device is properly configured.

cat /proc/mdstat

It should contain something like this:

md0 : active raid1 sda1[1]

6. If from the raid setup, then the inner filesystem is ext3, then you just need to mount it to a temporary directory

mount /dev/md0 /mnt/recover

7. Done.

Linux is often used for network routing because it is cheap to set up, it is efficient, and it runs on old computer hardware. However, if you are not already familiar with Linux, the set-up can be daunting. If you only have simple routing requirements then a Windows box can be used as the IP router.

By default, for security reasons, Microsoft turns off routing between the Ethernet cards. However, if you need to route, the option can be turned back on.

To set up a Windows box as an IP router do the following:

1. Take a spare PC with Windows XP or Vista on it to use as the PC router.
2. Ensure that there are two or more Ethernet cards installed in the PC.
3. For each of the installed Ethernet cards, assign an IP address from a different subnet.
4. Enable routing between the Ethernet cards:
   • regedit
   • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
     • Change IPEnableRouter from 0 to 1
   • Reboot
5. Connect a second PC to a network that is attached to one of the Ethernet cards in the PC router. Using the second PC, attempt to ping each of the Ethernet cards in the PC router. You should be able to ping devices on other subnets through the PC router.
6. Note: If your second PC’s default gateway is not the PC router then you may need to add additional static routes using the route add command.

There are innumerable reasons why Word may crash.  In my case Word crashed because of a printer driver problem.

Apparently when Word first opens a document, it queries the printer driver settings for your default printer.  In my case something conflicted between the settings within some documents and my default printer driver settings.  Tested in both Word 2003 and Word 2007, Word would simply crash a few seconds after opening the document.

Deleting the default printer from the Printer applet in the Windows Control Panel and re-adding the printer solved the problem.

Need to change the order that network adapters show up in Windows?

Vista:

• Start -> Control Panel -> Network and Sharing Center
• Manage Network Connections
• Alt-N
• Advanced Settings
• Adapters and Bindings Tab
• In the Connections box, click on a connection and press up or down to modify its binding order.

XP:

• Start -> Control Panel -> Network Connections
• Alt-N or Menu -> Advanced
• Advanced Settings
• Adapters and Bindings Tab
• In the Connections box, click on a connection and press up or down to modify its binding order.

Windows often remembers hardware bindings for devices that are no longer connected to your computer. Sometimes these old bindings cause problems.

To view the bindings for non-present hardware you need to do the following:

• Start -> Run -> cmd
• At the cmd prompt type:
  • set DEVMGR_SHOW_NONPRESENT_DEVICES=1
  • devmgmt.msc
• When the Device Manager console starts select the menu item View -> Show hidden devices

Non-present devices will now show up greyed out in the device manager tree. Remove the troublesome device by selecting it and pressing the “Delete” key or Right-clicking and selecting Uninstall.

Warning! Don’t delete any devices that are required to boot your computer. Plug-and-Play devices are generally safe to remove (ie. USB, PCI, etc…)

By default, XP mode virtual machines in Windows 7 are configured to use an internal Virtual PC NAT device.  In order to connect your XP mode virtual machine (VM) directly to your local network you’ll need to change the VM’s network settings to bridge to your local Ethernet card.

In Windows 7:

• Start -> All Programs -> Windows Virtual PC -> Virtual Machines
• Right click on your virtual machine configuration file.  e.g. Virtual Windows XP.vmcx
• Select Settings from the right-click menu
• In the Virtual PC Settings dialog, select Networking on the left.
• Change the Adapter drop down box on the right from Shared Network (NAT) to the name of your Ethernet card.
• Press OK
• Start/Restart the XP VM image.

The Process Explorer utility in the Windows Sysinternal Suite allows you to search for the  processes that currently have open handles to a particular file or DLL:

1. Launch Process Explorer
2. Menu: Find –> Find Handle or DLL…
3. Enter the filename that is locked.
4. Press Search

Reference:

• http://windowsxp.mvps.org/processlock.htm

Note:

• In Windows XP development environments, where Visual Studio is running,  I have run into an error condition where no process is listed as holding a file lock; however, the file can’t be deleted because the OS still thinks that the file is locked.  This issue occurs most often when Windows XP is running in a VMware session; however, I have also seen the problem occur on a plain XP host.  The only solution to releasing the lock is to reboot and attempt to delete the file again.  Interestingly enough, I have not seen this issue occur in Vista.

Ran across this little gem in a discussion on firewall configuration and packet filtering:

    The Pledge of the Network Admin

    This is my network.

    It is mine 
    or technically my employer's, 
    it is my responsibility 
    and I care for it with all my heart

    there are many other networks a lot like mine,
    but none are just like it.

    I solemnly swear
    that I will not mindlessly paste from HOWTOs.

Custom made wooden Tux cufflinks. Perfect cufflinks for the IT man!

Who is Tux?

Tux is a penguin character, the official mascot of the Linux operating system. Originally created as an entry to a Linux logo competition, the image of the mascot is the most commonly used icon for Linux, used in many flavors showing Tux in one way or another. He is also used in many Linux games, which are usually look-alikes from other mainstream games.

I’ve been an openSuSE user for almost 3 years, and just recently shifted to Ubuntu not for feature wise but for “just work” advantage, and upgrade management is a breeze. Now, back to the topic. Configuring SANE in openSuSE is somewhat much easier than in Ubuntu because of YAST (Yet Another Setup Tool). Installing and sharing a scanner to network is easy as 123. But in Ubuntu, you have to do it manually on SANE configurations. Few kicks more and you will learn it with this HOWTO:

1. Install necessary packages to share SANE over the network. You need to run it in xinetd, to install it run the usually apt-get
command.

         sudo apt-get install xinetd

2.  Then create a sane xinetd service

sudo vi /etc/xinetd.d/sane

3.  Enter the following code as ease. Note the you have to use root in the user and group option

service sane
{
   socket_type = stream
   server = /usr/sbin/saned
   protocol = tcp
   user = root
   group = root
   wait = no
   disable = no
}

4. Then restart the xinetd service.

sudo /etc/init.d/xinetd restart

5.  To access the shared scanner over the network, modify the client’s /etc/sane.d/net.conf and add the IP address of the SANE
server/host.

6. Done.

sudo apt-get install xinetd
