What Wireless Connector do I have?

Many people wonder what connection they have when extending a wireless antenna.  We have used Fab-Corp for years and they have a good site on explaining and showing the different connectors if you want to add an antenna.  Link

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.

Installing Linux Lite – A mini review

Home users that ONLY check email and use very few other programs may consider replacing their OS.   Linux has made an exceptional gain over the past several years with a Programs (Add/Remove) component and with hardware drivers.

To see just how Linux Lite stacked up other OSs, I decided to load it in Oracle’s VirtualBox.  The little over 600+mb download is comparable in size to Windows XP.  The ISO can be burned with an image burner to make a bootable CD/DVD.  Before you decide to switch, remember there are limitations to Windows software even with Wine.  Wine is a software application that allows you to run Windows programs.  Hunting around the internet you’ll find hundreds of Linux programs comparable to Windows programs.  You don’t have to look far considering the Linux repository has hundreds of programs.

After loading Oracle’s VirtualBox, simply walk through the New OS wizard, select Linux, allocate 2 GB of RAM and 8 GB of HDD space if you can.  Once you have completed this step, click on Settings and select bridge on the Network Card and load the ISO under storage.

Once you complete that step, start the OS and follow the on screen prompts.

Checking for updates is easy.  Simply click on the menu and select update.  Provide your login password and Linux Lite does the rest.

Printer setup

If you have a printer that supports IPP Protocol, login to the printer’s web address and Enable IPP.   The printer in our home is the Samsung SCX-3400 wireless.  An inexpensive laser printer that provides for thousands of pages with Samsung’s toner cartridge.  The printer provides hundreds of options for Windows, Apple, Linus or mobile devices.

What programs come with Linux Lite?  Hundreds of items.  Here’s the main categories.

  • Graphics  (Gimp and more)
  • Accessories
  • Internet (email and browsers)
  • Multimedia

  • Settings

If you ONLY use the internet and want to look into an alternate operating system.  Linux Lite may be for you.  It is easy to use, install and offers hundreds of programs.

Protecting your network by pen testing it

This post is for educational purposes and any use of these tools against a network without explicit permission could be illegal.   Metasploit is designed to identify weaknesses in networks and hardware/software on a network.  Do NOT use metasploit for other reasons.

Want to protect your network and the computers in your network?  You can get updates for your operating systems (Linux, Mac, iOS, Android, Windows or whatever) along with updates for third party programs yet you can still be unsecure.    When updating these products, you also have to remember firmware and updates for wireless devices, access points, bridges, firewalls, routers, switches, SCADA devices, robots, mobile devices, printers and any device on your network.

Metasploit

http://www.metasploit.com/download/

Metasploit Community is free and allows for a free scan of your network or server. Although limited (Try Pro for details and Brute Force), Metasploit Community is a first step in finding open services and ports on your operating system, hardware devices such as routers and other devices.   The trick to installing Metasploit is to disable your antivirus or make exceptions to what your antivirus finds.   You should truly install the software inside of a VM (Virtual Machine) so that your computer remains protected.

You can use Metasploit to protect your network by ‘seeing’ what a hacker or malicious person would see.  Truly for network professionals and auditors, this software can help you identify services, ports and weaknesses in your network.

There are several versions of Metasploit – Community, Pro, Express and Framework (Compare Editions)
