From your statment below, I take it you are running Linux. You should download the util 'ip' from the ip-routing package at ftp.inr.ac.ru. It contains a handy interface to v4/v6 configuration of your devices.

| > question : | > the device name of ethernet card for ipv6 is sit0 sit1 sit2 etc etc??? No. The names sit* are for tunnels. Your ethernet NICs are eth* in Linux, and you can configure eth0 devices just the same as in IPv4: ip -4 addr add 10.0.0.1/24 dev eth0 ip -6 addr add 3ffe:8110::1/64 dev eth0 | > if not, how can i set ipv6 address for every interface that i have? Use ip (check out its syntax first). Also check out various webpages which handle these things. Google for 'bieringer ipv6' for an excellent start. Check out my FAQ on www.sixxs.net if you want an alternative. groet, Pim -- ---------- - - - - -+- - - - - ---------- Pim van Pelt Email: pim@ipng.nl http://www.ipng.nl/ IPv6 Deployment -----------------------------------------------
