...it's not so easy than it's look like...
hello!
yesterday i bought an arduino mage2650 and an ethernet shield.
after solving a few problems with my distro i was able to established a connection to the board.
first i tested some analog-examples --> worked fine!
now i try to setup one of the examples for the ethernet-library but no one seems to run correctly.
if i upload the webserver-example to the board, i can't access them from my browser. (mac and ip are configured).
so i tried the chatserver-example which should replay any incoming character. i established connections with two pc's to the board but no massages where served from the board.
for the telnet-connections i used putty on both systems.
i can ping the arduino-board and nmap shows open ports correctly
has anyone a suggestion to solve this?
thank you!
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
