Version: 2.19-20
Severity: normal
Tags: upstream fixed-upstream patch
Hello,
without nscd:
$ ping6 -n kamino
PING kamino(2001:db8:210::20) 56 data bytes
64 bytes from 2001:db8:210::20: icmp_seq=1 ttl=64 time=0.303 ms
with nscd:
$ ping6 -n kamino
PING kamino(a00:d214:2001:db8:210::) 56 data bytes
(0x0a.0x00.0xd2.0x14 happens to be the IPv4 of kamino)
This is due to a missing commit backport for Bug#798515. I have pushed
the missing commit in the upstream 2.19 branch (8dc9751 cherry-picked as
b0f0937). We can either upload a 2.19-23 to get it fixed, or just wait
for 2.21 (which already has the fix) to get uploaded.
