PaulS:
You want to establish a telnet session with Google? Does that really make sense?You appear to be mixing code for a telnet server with code for a web server. Why?
What are you really trying to do?
What is the given TelnetClient example trying to do? I just want to run the example with the least changes, such as providing my mac address, ip, and server ip. Maybe there is something more that needs to be added after EthernetClient client; ??
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,177);
// Enter the IP address of the server you're connecting to:
IPAddress server(1,1,1,1);
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 23 is default for telnet;
// if you're using Processing's ChatServer, use port 10002):
EthernetClient client;
Given Example Provided by Arduino 1.0.1
/*
Telnet client
This sketch connects to a a telnet server (http://www.google.com)
using an Arduino Wiznet Ethernet shield. You'll need a telnet server
to test this with.
Processing's ChatServer example (part of the network library) works well,
running on port 10002. It can be found as part of the examples
in the Processing application, available at
http://processing.org/
