Can not perform ChatServer and ChatClient, help me!

dxw00d:
What are you actually trying to achieve?

You can upload either of the sketches to the Arduino/Ethernet shield. If you upload one, then the other, the second will overwrite the first.

What I am trying to achieve is I can chat between this two of my netbook and notebook using ChatServer and ChatClient.

Hmm, how I can upload the sketch to Ethernet Shield since I use only LAN cable to connect it to my netbook?

Both the ChatServer and ChatClient have to run on an Arduino/Ethernet shield

How you do this?Can you tell me the steps?
