Wired Networking
To get your Raspberry Pi on the network, you'll need to connect an
RJ45 Ethernet patch cable
between the Pi and a switch, router or hub. If you don't have a router or hub, you can get your
desktop or laptop talking to the Pi by connecting the two directly together with a patch cable.
Usually, connecting two network clients together in this way requires a special cable, known
as a
crossover cable
. In a crossover cable, the receive and transmit pairs are swapped so that
the two devices are prevented from talking over each other—a task usually handled by a
network switch or hub.
he Raspberry Pi is cleverer than that, however. he RJ45 port on the side of the Pi (see
Figure 1-7) includes a feature known as
auto-MDI
, which allows it to reconigure itself auto-
matically. As a result, you can use any RJ45 cable—crossover or not—to connect the Pi to
the network, and it will adjust its coniguration accordingly.

Ethernet port
If you do connect the Pi directly to a PC or laptop, you won't be able to connect out onto the
Internet by default. To do so, you'll need to conigure your PC to
bridge
