Hi This is what I did in Linux (gentoo with kernel 2.6.10) 2> inet:getiflist(). {ok,["lo","eth0"]} And this what I did in Windows XP 5> inet:getiflist(). {ok,["240.802.170.641","100.0.0.721"]} Both of them running R10B-6. Is this work as designed or not? The function is public but documented. regards,
