user36969: I'm beginner here at arduino stuff. i just started learning arduino and i have this small homework where i NEEDED to connect 2 arduino using ethernet shield or module ONLY over a distance of 20 meters.
I don't have my modules yet but i want to atleast study it now while i'm waiting for it. I can't seem to see any tutorials about it nor anyone tried it. How can i do this? i hope you can help me and give some insights, links, etc reference. Thanks :)
EDIT:
I had in mind where these arduino will have their own identity, 1st arduino will be receiving only some data coming from 2nd arduino. The 2nd arduino will have sensors and read them then sends them to 1st arduino. Now, i like my 2nd arduino to have a power source coming from the 1st arduino to save power supply installation and since it'll be like a remote arduino. Thus has anyone has experience applying PoE on arduino?

user37622: You will need a crossover cable to connect two Ethernet shields peer to peer.
Then you configure the Ethernet library to use static IP address. Use 192.168.1.1 and .2 address. (Or other 192.168.x.x address). Set subnet 255.255.255.0. Gateway should be the IP address of the other Arduino.
