Is there any #define to enable it or must I modify some sources file to do this?

if setenv nc 'setenv stdout nc;setenv stdin nc have succed, with run
nc, it is switched
But, i've seen with ethereal that no packets where transmited through
my eth interface
It might be the first step to solve this problem
