I suspect this is an issue with the resolver, but it could also be in =
host. I have the following in /etc/resolv.conf:
# Generated by resolvconf
nameserver fe80::213:72ff:fec3:180f%bge0
nameserver fe80::120c:6bff:fee9:cdf7%bge0
There is a DNS server running at the first address that supplies IPv6 =
addresses. When I ping the first address, it succeeds:
test# ping fe80::213:72ff:fec3:180f%bge0
PING6(56=3D40+8+8 bytes) fe80::6a5b:35ff:fed3:4eda%bge0 --> =
fe80::213:72ff:fec3:180f%bge0
16 bytes from fe80::213:72ff:fec3:180f%bge0, icmp_seq=3D0 hlim=3D64 =
time=3D0.321 ms
16 bytes from fe80::213:72ff:fec3:180f%bge0, icmp_seq=3D1 hlim=3D64 =
time=3D0.553 ms
16 bytes from fe80::213:72ff:fec3:180f%bge0, icmp_seq=3D2 hlim=3D64 =
time=3D0.544 ms
16 bytes from fe80::213:72ff:fec3:180f%bge0, icmp_seq=3D3 hlim=3D64 =
time=3D0.424 ms
However, host client.global.example return an error:
test# host client.global.example
;; connection timed out; no servers could be reached
ktrace of host shows that either host or the resolver is trying to use =
the address without the %bge0 which is why that error occurs:
2027 host STRU struct sockaddr { AF_INET6, =
[fe80::213:72ff:fec3:180f]:53 }
2027 host RET sendto -1 errno 51 Network is unreachable
Is this a bug or is there some configuration item I have missed:
