On some machines I completely removed IPv6 by commenting "options INET6" in the kernel. I've recently upgraded one of these from 13.2 to 13.3 and now ping is behaving differently from before. > % host www.google.it > www.google.it has address 216.58.204.227 > www.google.it has IPv6 address 2a00:1450:4002:415::2003 > % ping www.google.it > ping: socket ssend: Address family not supported by protocol family > % ping -4 www.google.it > PING www.google.it (216.58.204.227): 56 data bytes > 64 bytes from 216.58.204.227: icmp_seq=0 ttl=117 time=13.422 ms > 64 bytes from 216.58.204.227: icmp_seq=1 ttl=117 time=15.746 ms > ^C On 13.2 and 14.0 (and every previous version I ever used), the first ping ("ping www.google.it") behaves exactly as if "-4" was given. I din't read anything about this change in release notes (unless I'm failing to understand something) and the ping man pages are identical. Is this some regression? Do I need to set something? Are others seeing this? Shall I report this as a bug? bye & Thanks av.
