You usually get this problem when your interface (ethX) has not been assigned a global IPv6 address. But you seem to already have done this. Try pinging yourself: # ping6 -I eth1 ::1 If you still get this error then something is buggered. Try reloading the ipv6 module. br. -- =============================== Polychronis Ypodimatopoulos MSc Software Engineer Defense Systems Development INTRACOM S.A.
