The default reference design shipped on the Nios development board
implements a web server, among other functions. The Ethernet port
provides a very fast and easy method to download hardware and
software images to the board via a web browser on your host computer.
The software reference design implements a web server on the Ethernet
port as soon as the board powers up and configures with the factory-
programmed safe configuration. The web server responds to any HTTP
requests, regardless of origin, that arrive on its Ethernet connection.
This section assumes that you are familiar with the Nios SDK shell, the
nios-run utility for serial communication with the Nios development
board, and the GERMS monitor.

Connecting the Ethernet Cable
The Nios Development Kit includes an Ethernet (RJ45) cable and a
male/female RJ45 crossover adapter. Before you connect these
components, you must decide how you want to use the network features
of your board. Select one of the two following connection methods:
1. Point-to-Point Connection — To use your Nios Development Board
connected directly to a host computer point-to-point (not on a LAN),
do the following:
a. Connect one end of your RJ45 cable to the female socket in the
crossover adapter.
b. Insert the male end of the crossover adapter into RJ1 on the Nios
Development Board.
c. Connect the other end of the RJ45 connector directly to the
network (Ethernet) port on your host computer (see Figure 25).
