hello, I've installed a DNS IPv6 and it works fine when I use the tools nslookup and dig : #nslookup ... set q=AAAA "hostname" give me the IPv6 address and other informations, the reverse request works fine too. #dig "hostname".domaine give me too good informations. But when I try to make request with ping : ping -s -A inet6 "hostname", it gives me the follow ligne : ping: host unknown "hostname" In /etc, I 've configured the files hosts, nsswitch.conf, resolv.conf ...and I've also edit the file hostname6.eri0 as follow : # touch /etc/hostname6.eri0 (eri0 is the current interface which support IPv6). This is contains : addif "address IPv6" up I've fixed this address, because I only want to make tests IPv6 of DNS, and I don't have any IPv6 router with autoconfigration for have a global address IPv6. So my question, is to know if someone knew how to configure the hostname6.eri0 for introduce a hostname and ping with this hostname ? I've tried to edit hostname6.eri0 in writing in this file the name which i would to configure my interface "hostname" but it doesn't works... hope that someone can help me. Thanks . Lionel David
