Uhhh. That doesn't look remotely DNS-related. To be absolutely sure,
though, try using the -n flag, which disables (reverse) DNS lookups.
# ping6 -n ::1
That looks like firewalling is preventing the packets from being sent,
to be honest. I'd be looking more at something like:
# ip6tables -L -n
Which is totally outside the scope of this mailing list, but I try to
be helpful...oh, here:
# ping6 -n ::1
PING ::1(::1) 56 data bytes
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.043 ms
^C
# ip6tables -A OUTPUT -j REJECT
# ping6 -n ::1
PING ::1(::1) 56 data bytes
ping: sendmsg: Operation not permitted
^C
That's my theory.
Good theory - I hadn't realised that there is ip6tables. IPv6 is a big blind
spot for me - in all my playing around with iptables and searching for a
solution, I never once registered that I need ip6tables - although I see it now
under the iptables man page SEE ALSO.
And I see my machine has all chains set to DROP, so you're right.
Thanks alot.
