Cipher /w:C securely erasing unused space

The Cipher program can be used to remove any erased data from unused disk space.  The command, Ciper /w:C is used to perform this action and can securely erase data that you once had on your computer.  While this command is relatively safe, you should always have a backup of your critical data.

If you want to do this to make sure files are deleted properly you have to remember a couple of things.  Only do this when the computer can set idle for several hours.   Another thing you have to remember is that if you interrupt this process, the Ciper command can fill up your hard drive with temporary files.   If you have to interrupt this process, you may see you have a lot of space that is suddenly missing.  Use Space Sniffer to find where the temp files were written so that you can erase them.

You can securely erase other drives by replacing the C in the command above with the drive letter of your choice.

Configuring WDS to extend your wireless network

Want to extend your network and make it more reliable and robust?   

Here’s what you will need -

  • Two routers with the same firmware
    • Preferably Tomato or DD-WRT

Login to the first router.  

In this example, the static number 192.168.1.1 is the Main router.

  • Enable the WAN to match your ISP  
  • Enable DHCP
  • Enable Access Point + WDS  (Picture two below)
    • You must have the same wireless configuration on both routers
      • Enter the MAC address of router two under WDS Link with.

Router 1 no 1

Router 1 no 2

Login to the second router

  • Disable the WAN
  • Disable DHCP
  • Assign the router a static IP address (Below we have given the router .250)
  • Enter Router One’s IP Address for the Gateway
  • Enter a DNS of your choice
  • Make the wireless configuration the same as the first router.  Under WDS, change the drop down to automatic.

Router 2 no 1

Router 2 no 2

With the same settings, you can now extend your network several hundred feet under the right conditions.  Because the SSIDs are the same, once you join one of the routers with a smartphone or laptop, it will seamlessly change to the stronger signal.

With Tomato, you can chain together approximately 12 devices.

Note; The IP addresses and MAC addresses are in a lab environment.

How does it look on a network map?  The two routers are actually connected together.  The switch is the four ports on the back of the router closest to the internet.
