Read the documentation files that come with the patch. These
instructions might indicate it is necessary to patch the driver

with the rmmod and
insmod commands:
foo@bar:~$ rmmod orinoco
foo~bar:~$ insmod orinoco
Running Kismet
Kismet is a special tool that can scan for wireless networks and indicate which
ones are available for you to connect to. Kismet is packaged for many Linux
distributions and the source code is available at http://www.kismetwireless.net.
Detailed instructions on how to install and set up Kismet are included with
the software, so I won’t cover that here. The documentation will require you
to make some adjustments to your /etc/kismet.conf file, which controls Kis-
met’s configuration. When you are reading the documentation, you should
pay particular attention to the suiduser and PID parts, as these could cause
problems with Kismet running.
To start Kismet, run the command-line program:
foo@bar:~$ kismet
When the program starts, you see an interface that displays a list of net-
