Hi,
I've just acquired an Ethernet shield for the Arduino and I want to do development with it connected to the LAN adapter on the laptop.
So - a point of information for anyone doing the same thing - when you connect the Arduino to the LAN adapter, you need to make sure that DCHP is switched off for the adapter and assign it an IP address, otherwise it will get stuck in 'acquiring network address'.
Otherwise, works fine.
PS: what I really want to do is connect it to my Centos box - but getting the Arduino s/w to run under Centos :o
