In-Depth Information
5. Your Wi-Fi adapter will associate immediately with the access point
and should receive an IP address, as listed under the
Current Status
tab.
6.
From the
File
drop-down menu, select
Save Configuration.
.
7.
Exit the application and log out of the desktop environment.
To find out about the leased IP address of your Wi-Fi adapter (
wlan0
), without
having to enter the graphical desktop, use the following command:
pi@raspberrypi ~ $ ip addr show wlan0
You should see a line similar to the following output:
inet 192.168.1.15/24 brd 192.168.1.255 scope global wlan0
The digits between
inet
and the
/
character is your Pi's IP address,
192.168.1.15
in this case.
To obtain information about the associated access point and signal quality, use the
iwconfig
command.
Connecting to the Pi from Windows
We will be using an application called
PuTTY
to connect to the SSH service on the Pi.
The steps to be followed are:
1. To download the application, visit this address
http://www.chiark.
2. Download the all-inclusive windows installer called
putty-0.63-
installer.exe
, since the file copy utilities will come in handy in
later chapters.
3. Install the application by running the installer.
4. Start
PuTTY
from the shortcut in your Start menu.
5. In the
Host name (or IP address)
field, input the IP address of your Pi, which
we found out previously. If your network provides a convenient local
DNS
service, you might be able to type
raspberrypi.
(with the trailing dot)
instead of the IP address; try it and see whether it works.
6. Click on
Open
to initiate the connection to the Pi.
7. The first time you connect to the Pi or any foreign system over SSH, you'll
be prompted with a warning and a chance to verify the remote system's
RSA key fingerprint
before continuing. This is a security feature designed
to ensure the authenticity of the remote system. Since we know that our Pi is
indeed
our
Pi, select
Yes
to trust this key and continue the connection.
