Broadcast Multiple SSIDs From One Computer

NetworkList

 

MDK3 is a Linux program that will allow you to do all sorts of things with wireless beacon frames.  One of the things you can do is broadcast a list of fake access points from a single wireless card. Good for illustrating that users shouldn't just connect to any open AP that they come across.

SSH Tunneling

SSH tunneling has been my favorite way to quickly tunnel to my home network over the years. The setup is incredibly simple, and if you have a Linux machine at your home or office, and use Linux on your travel computer, then you have very little to do to make this work.

The Linux machine on your home network needs openssh server installed. (Server distros usually ask if you want openssh installed initially or have it installed by default)

Forward the SSH port on your router/NAT device to the Linux box at home. (port 22 by default)

Now on the Linux notebook you only have to open a terminal and run your normal SSH command with the -D option.

Example:

ssh john@server -D 8080

This allocates a socket to listen to the local port you specify (in this example port 8080).

Then configure whatever application you want to use the tunnel, to a socks proxy pointing to the localhost at port 8080 (or whatever port you specified).

For example, you would setup Firefox to use the tunnel by going to Preferences>Advance>Networking>Conection Settings, and select Select SOCKS Host with 127.0.0.1 and port 8080 as the setting.

Find the Right Channel for Your Wireless AP

If you're setting up a new wireless router (or just curious about the wireless networks in the area) check out inSSIDer. InSSIDer makes it easy to see what channels the other access points use, as well as what encryption is in use (if any), and the brand of the AP. This is very helpful for choosing a less used channel for your router, and if you're a tech it can help with enumerating a client's setup.

InSSIDer is available for Linux and Windows. It has deb and rpm packages making the Linux install easy.
