All In One FREE Data Recovery Suite

What's On My PC

Recently I featured an article, titled A Successful Data Recovery Story Using Some Desperation Moves where the hero of the day was a software application called MiniTool Power Data Recovery.

MiniTool Power Data Recovery

I realize there are numerous undelete recovery apps out there, but for some reason I always go to this app to get the job done. I have found it seems to dig a little deeper than most when recovering deleted data.

In addition, MiniTool Power Data Recovery is a “data recovery suite” which means it does more than the standard apps that are available.

For example, MiniTool Power Data Recovery has the ability to:

Recover formatted disks or partitions
Recover damaged partitions
Recover lost partitions
Recover CD & DVD disks
Recover Photos & Flash Memory cards

Home users can use MiniTool Power Data Recovery software to recover their lost data in any condition for…

Your Wireless Printer may be giving away your documents

When installing any device such as home routers and printers, you should always password protect these devices.  During our studies in Network Security in the past, we studied perimeter security and how it was at the firewall.  Today because of wireless, perimeters are extended well beyond most property lines.

What does that mean?  Someone can drive by and gain access or go across the internet if a public ip address is given to the printer.  With simple Google searches anyone can find these printers.  No, we aren’t going to give you the answer on how to Google these unsecure printers but you do need to secure your printer(s) if they are unsecure.  (During the setup, set a login other than the default for any device you put on your network).   There is code on the web to gain access to your network and computers through some of the printers.   Script Kiddies and hackers that can get access can connect to the printer and print hundreds of test pages or change settings just to be malicious.

Note: Mobile computing also extends your perimeters globally…security is one of the most important areas that all IT personnel and employees need to be trained in.

One in four wireless networks are still unsecure

Annually our class studies wireless technology and its implementation into homes and industry.   Surveys are conducted to analyze security used, transmit power and geographic location of wireless technology.

According to Wigle.net, Security has improved over past years.  Home users are still setting up their wireless wrong by not providing a WPA2 (AES) form of encryption.

Approximately 23% of home users still have open internet that neighbors or anyone passing by can use.    Vendors have tried to make setting up wireless easy and secure by providing WPS and/or a setup utility disk that walks the user through step by step.  Once you have secure wireless, you should change the password periodically to prevent users from learning what your passphrase is.

Wigle provides a map of wireless throughout the globe.  As users find wireless, they upload their data to Wigle and the database is free to the public.

With GPS technology today, anyone including malicious wardrivers can map out coordinates of unsecured wifi.  Make sure you secure your wifi.

Note:  During a survey we do not use packet analyzers or methods to see data on the wireless networks.

Network troubleshooting with Netsh

Every have that laptop or netbook that connects to your computer but won’t go online at another location? You can quickly rebuild the IP stack and force the computer to get online at another location by typing the following command:

netsh int ip reset C:iplog.txt

Of course if you have a computer that won’t get online even if it has an ip address, do several things –

  • Click Start Menu, type cmd in the search box or run box ( Hold down Ctrl + Shift and hit Enter)Type the following commands, each followed by pressing enter.
  • ipconfig /flushdns
  • nbtstat -R
  • nbtstat -RR
  • netsh int reset all
  • netsh int ipv4 reset
  • netsh winsock reset catalog
This will rebuild the tcp/ip protocol stack (fully)

After rebooting, run a command prompt as an administrator and type:

  • netsh interface tcp set global autotuninglevel=disabled

Reboot


How about tweaking your network for a little more speed?

Here’s a set of quick tweaks to adjust Windows 7 networking.  Always backup your computer before performing any tweak.

Open a command prompt as an administrator and type the following –

netsh int tcp set global congestionprovider=ctcp
netsh int tcp set global ecncapability=default
netsh int tcp set global chimney=enabled
netsh int tcp set global dca=enabled
netsh int tcp set global netdma=enabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set heuristics disabled

CTCP or Compound TCP – Improves throughput
ECN-provides routers with an alternate method of communicating network congestion
TCP Chimney Offload – Offloads all TCP processing for a connection to your network adapter
Direct Cache Access (DCA) – or direct cache access allows a network controller to deliever data directly to your cpu cache
NetDMA – enables support for advanced direct memory access.
TCP Autotuning – RWIN auto tuning behavior
Heuristics – Windows 7 has the ability to automatically change its own TCP Window auto-tuning behavior

To return to your default settings, go to a command prompt as an administrator and type –

netsh int tcp set heuristics default
netsh int tcp set global chimney=default
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=default
netsh int tcp set global ecncapability=default
netsh int tcp set global netdma=disable
netsh int tcp set global dca=auto

If you have trouble navigating to sites and time out to Facebook or Microsoft for example, or you want to improve your download speeds -you may need to set your MTU settings –

So what do you set your MTU to?  Normally your MTU is set to 1500.   Every connection is different.  First log into your router if you have one and set it to 1492.  Retry the sites that are timing out.  If this did not work, you may need to set the MTU on your network card.

Use TCPOptimizer for Windows XP, Vista or Windows 7 (easy) –

or you can go to a command prompt (as an administrator with elevated privileges) and type –

netsh interface ipv4 show subinterface

(to see the name of your network Interface – it is important to write down the MTU settings and network interface name at this time)

To set the MTU value to 1472 (you can also try 1492, type the following command at a a command prompt (Note: You MUST substitute the name of your network connection  –

netsh interface ipv4 set subinterface “The Name of Your Connection” mtu=1472 store=persistent

Many users have reported an increase in download and internet speeds after adjusting their MTU to 1472.  This setting may not be the optimal setting everyone.

Modify LLMNR by doing the following:

Modify Group Policy – Go to Search – Type GPEdit.msc – Enter – Navigate to the following and make sure Enabled is checked – Computer Configuration\Administrative Templates\Network\DNS Client
\Turn off Multicast Name Resolution = Enabled


How is your network card and computer routing?

Use the following command to see the routing table – from the command prompt type –

netsh interface  ipv4 show route

Publish  Type      Met  Prefix                    Idx  Gateway/Interface Name

Change network adapter priorities in Windows 10 – PowerShell

First thing –

  • disable network adapters you don’t use
  • If you use Ethernet, disable everything but flow control
  • Disable LLMNR
  • Adjust NTLM
  • Perform test with Totusoft’s network speed test

Next, avoid latency of your network card by adjusting the network adapter priorities.

Open PowerShell as an Administrator – Type Get-NetIPInterface

netipinterface

You will see the Interfacemetric numbers that vary from 11 to 90.

If you want a higher priority, set the interface to a lower number – I use wi-fi – therefore I can type the command –

Set-NetIPInterface -InterfaceIndex “11” -InterfaceMetric “11”

adjusted

Our old article on using the GUI 

If you use more than one network card for mutliple LANS or connections, you can set the metric of each card to send IP packets through the fastest card first or the desired card.

For instance if you have a network card that connects to other servers and computers on one LAN and a network card that connects to a separate LAN that has security cameras; metrics can be used to compute the routing algorithm.

The one card would be set to a lower metric in order to go to the web and the security camera system would be set to a higher metric thus giving priority to the lower number.

Here’s an example of my home LAN which uses a printer and cameras on a separate network and my wireless which connects to the Internet.

So how do you change it?  Open the Network and Sharing Center – Click on Adapters – Right click the desired adapter – Select Properties – Double click TCP/IP – Click Advanced – Uncheck the Automatic Metric – Change to the desired number

Wireless

Above the wireless is set to 1.  Below the LAN which has a static IP address and no Gateway is configured with a 20.

Valid values are 1 to 9999.

Don’t forget to set the binding order of the network cards.   Go to the Adapter.  Hit the ‘Alt’ key once for the menu.  Click on Advanced and then Advanced Settings.

Move the network card with a higher priority to the top.

Link aggregation – Use Multiple NIC Cards

There is truly an advantage to adding multiple NIC cards to a computer.   It won’t speed up a single internet connection but it can help with loss of signal, detecting access points, transferring information to and  from computers.

When adding a second NIC card to a computer, you can highlight both by holding down the CTRL key and clicking on them and then right clicking to bridge the connections so they act as one…this can allow you to bridge a wireless network to a wired network.

Internet or network application slow? You may need to temporarily disable Nagle’s Algorithm

With the Nagle-Algorithm, Windows takes small packets and packages them in to more manageable and efficient sizes.   If you have poor latency, you might try to disable the Nagle-Algorithm.  Nagle’s algorithm helps to control congestion when small packets are sent continuously by TCP.   When enabled, this helps to prevent a flood of these packets.

More information – http://en.wikipedia.org/wiki/Nagle’s_algorithm

How to disable Nagle’s algorithm-

Open regedit.exe.  Navigate to HKey_Local_Machine\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\

Find the interface that has your current IP address (see example below)

Find IP address

Add the following values and make sure they are set to 1.

TcpAckFrequency and TCPNoDelay

Add values

This is only a temporary fix for the reduction of some applications on the internet.  Once your project or need is fulfilled, you should re-enable the algorithm by deleting the keys and rebooting or changing the values.

Is your AHCI Link Power Management viewable from the Power Options Console?

If you can’t see your AHCI Link Power Management from the Power Options, there is a way to add it.  Always backup your computer before modifying the registry.

ahci-link-power-management

You can add the GUID to the registry by going opening the registry (regedit) and creating  a key under the following key -0012ee47-9041-4b5d-9b77-535fba8b1442

The easiest way is to copy the information in italics to notepad or notepad++ and save as AHCI.reg.

After saving this, double click on the .reg file and reboot.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60]
“Attributes”=dword:00000002

So what are the settings used for? Using DIPM can add 7% to 8% more battery time according to some articles.

ahci-link-power-management

Index Name Description
0 Active Link power management is not used.
1 HIPM Host-Initiated Power Management (HIPM) is used.
2 HIPM and DIPM HIPM and Device-Initiated Power Management (DIPM) are used.

NetSpot Review – Wi-Fi survey app for Windows

In this three part series we review NetSpot a Wi-Fi survey app for Mac and Windows.

In this part, we look at the Microsoft Windows version of NetSpot.  NetSpot performs accurate Wi-Fi surveys that allows you to use a map of your business, industry or home with dozens of other features.

NetSpot’s Discover Mode collects details about surrounding Wi-Fi networks and returns the data in a detailed table that provides information about the SSID, MAC address, Channel, Security, Vendor, Signal Information (including Average, Max and Min.).  This app also gives you Noise levels for wireless professionals to calculate an exact signal strength.  The real-time charts gives accurate information about 2.4 and 5Ghz frequencies.  NetSpot allows you to download historical information in a CSV file for accurate record keeping.  (More information on Discover Mode will follow in this series.)

The application can be downloaded from here.   The download is a tiny 1.2mb download.  The installation and operation is easy.

Operating the software in Survey Mode is easy.  Simply open the application, upload your map (selecting your approximate measurement) and start your survey by standing near your AP after selecting it, wait a few seconds and then click your mouse.   An accurate signal and information about the AP will give you a heatmap of the immediate area overlaying the information on the map.

To insure an accurate signal is measured it is import to stand in the area for a few seconds then click your mouse.   During our survey, we took several screenshots to show the accuracy of the application as we performed a very basic survey.

Given more time, and more mouse clicks, the accuracy of the survey will of course go up.

During the review, we used two identical laptops with identical drivers and operating systems (Windows 10).  With two individuals using NetSpot, you’ll find the accuracy of the initial survey between the screenshots below is very similar.

The individuals walked side by side to compare readings throughout the survey.

Laptop 1 (Titled Laptop Four 1 of 4 laptops assigned to the  area)

As you can see, this application is a critical application in today’s world because of wireless connectivity growth and complexity.  This application helps to show coverage area and is an important tool for IT professionals when verifying and troubleshooting your wireless connectivity.

Look for parts two and three in the upcoming weeks.  We will update this post and link each post as time permits.

Windows Cleanup shows 3.99TB? Is my math wrong?

Apparently there is a bug that shows 3.99TB of Windows Update Cleanup when you run the disk cleanup application in Windows 10.  With the plethora of updates that Microsoft has thrown at everyone, this would seem about right, however, you can’t clean 3.99TB from a 1TB disk.

Although I’m sure my disk is OK since the entire internet is reporting this.  It’s a good time to run a chkdsk just to be sure if you receive this.  The odds are that the app is reporting the 3.99TB falsely.

OWASP Zed Attack Proxy (ZAP)- Using on your home network

OWASP -The Open Web Application Security Project is an online community which creates freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security. (Wikipedia)

If you have wanted to learn how to test your network and the devices, you can begin with OWASP Zed Attack Proxy (ZAP).  Remember, when you get ready to attack, you must own the network and the devices on the network.

You can download OWASP Zed Attack Proxy from the link above.

Once you install the program, you may want to make exceptions in your anti-virus or anti-malware software. Plug-ins may be detected as viruses, however, this is common with security software.

no-worriesno-worries-2no-worries-3

Once you have installed OWASP Zed Active Proxy, you may want to update and add some components.  If you are new at scanning and testing security, be sure to look at the tutorials and OWASP videos below.  Again, make sure you own the network and devices on the network.
