[En-Nut-Discussion] Problem to connect a tcp socket

[Julien CHAUSSEC]

Hello everybody,
the problem i have is i can't connect a TCP socket to a server (who 
works). I use an example, of the ethernut software manual 2.3, page39 "a 
simple tcp client looks likethis:..." .
The NutTcpConnect() function return -1 and i really don't understand why.
The several printf show correct ip address (local & remote), but the 
local port number is 272 (i don't know why) and the remote port number 
is -28241 nevertheless i set the remote port number to 5010 with the 
NutTcpConnect() function!! The NutTcpError() function returns the value 
10064 --> "host is down".
I don't know what to do. If anyone have an idea?
Thank you.
