OK. In that case I'd recommend to use Ethereal. I do
not believe that "no one did not do anything".
Someone, either the PC or the Ethernut closes the
connection and Ethereal will show the FIN segments.

Btw., can you post the part of the code that calls
NutTcpReceive, including the declaration of the
buffer variable (and optionally the malloc, if one
is used)?
