Read inputs from an instrument connected with ethernet using arduino sheild

Hello all,
I have a question,

I know how we can read data from an analog pin and flash it to a website using arduino.

But I want to connect a device (which is only capable to send data through Ethernet) with arduino and take the input.

In fine, please give a solution / code of how to get data as an input from the ethernet port to the arduino sheild/arduino-which there after I can see from the serial port.

Thanks and regards,
Jayanta

You probably want to open a TCP socket between a Server and Client, look at the Ethernet Library
