Subject: [9fans] bug or feature ?  --- ip/ping -6
Date: Mon, 28 Dec 2015 18:04:34 +0900	[thread overview]
Message-ID: <4AE7714E-C18F-4897-ACC1-4F8D35C858AE@ar.aichi-u.ac.jp> (raw)

hello 9fans,

I have once posted the message below to 9front mailing list.
however looking the origin of the problem, now I think better place is 9fans.

== message posted to 9front mailing list ==

I am feeling weird that ip/ping -6 does not ping to ipv6 address with /lib/ndb/local.

#	sys=io
#		ip=192.168.0.5
#		ip=2402:6b00:22cd:bf80::5
#
hebe% ip/ping -6a io
sending 32 64 byte messages 1000 ms apart to icmpv6!io!1
	2402:6b00:22cd:bf80::6 -> 192.168.0.5
0: 192.168.0.5 -> 192.168.0.6 rtt 104 µs, avg rtt 104 µs, ttl = 255
1: 192.168.0.5 -> 192.168.0.6 rtt 85 µs, avg rtt 94 µs, ttl = 255
2: 192.168.0.5 -> 192.168.0.6 rtt 85 µs, avg rtt 91 µs, ttl = 255
3: 192.168.0.5 -> 192.168.0.6 rtt 85 µs, avg rtt 89 µs, ttl = 255

this weirdness comes from the order of ip attributes.

#	sys=io
#		ip=2402:6b00:22cd:bf80::5
#		ip=192.168.0.5
#
hebe% ip/ping -6a io
sending 32 64 byte messages 1000 ms apart to icmpv6!io!1
	2402:6b00:22cd:bf80::6 -> 2402:6b00:22cd:bf80::5
0: 2402:6b00:22cd:bf80::5 -> 2402:6b00:22cd:bf80::6 rtt 102 µs, avg rtt 102 µs, ttl = 255
1: 2402:6b00:22cd:bf80::5 -> 2402:6b00:22cd:bf80::6 rtt 88 µs, avg rtt 95 µs, ttl = 255
2: 2402:6b00:22cd:bf80::5 -> 2402:6b00:22cd:bf80::6 rtt 84 µs, avg rtt 91 µs, ttl = 255
3: 2402:6b00:22cd:bf80::5 -> 2402:6b00:22cd:bf80::6 rtt 104 µs, avg rtt 94 µs, ttl = 255

is this a feature or a bug?
