I'm running: "HP-UX glade B.11.11 U 9000/800 unknown"
I can look up IPv6 names with getaddrinfo(), but getnameinfo() is
failing. This C++ test program:
#include <stdio.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <netdb.h>
int main (int argc, char**argv) {
sockaddr_in6 sin6;
int err = inet_pton (AF_INET6,
"2001:470:1f00:1056:202:b3ff:fe1d:b515",
&sin6.sin6_addr);
printf ("inet_pton() returned %d\n", err);
sin6.sin6_family = AF_INET6;
sin6.sin6_port = htons(0);
sin6.sin6_flowinfo = 0;
sin6.sin6_scope_id = 0;
char hostbuf[NI_MAXHOST];
int flags = NI_NAMEREQD;
err = getnameinfo (reinterpret_cast<sockaddr *>(&sin6),
sizeof (sin6),
hostbuf,
sizeof (hostbuf),
0,
0,
flags);
printf ("getnameinfo() returned %d (%s)\n", err, gai_strerror
(err));
}
prints:
inet_pton() returned 1
getnameinfo() returned 8 (host nor service provided, or not known)
The address translates fine from the command line:
glade:test$ nslookup -type=ptr 5.1.5.b.d.1.e.f.f.f.3.b.
2.0.2.0.6.5.0.1.0.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa.
Using /etc/hosts on: glade
looking up FILES
Trying DNS
Non-authoritative answer:
5.1.5.b.d.1.e.f.f.f.3.b.2.0.2.0.6.5.0.1.0.0.f.
1.0.7.4.0.1.0.0.2.ip6.arpa name = kohaku.sarna.org
so I know it's a good address, and I know IPv6 is enabled on the
box. This works on my linux and solaris systems. Does anybody have
any idea what might be going wrong?
