Hi All, I have an IPV6 server in the pool: http://www.pool.ntp.org/scores/2600:3c00::f03c:91ff:feae:2e76
I am seeing a large number of error messages in my /var/log/messages related to IPV6 networks being unreachable. EG: (dump from logwatch) sendto(2002:a00:2:e472:219:9dff:fe44:2458) (fd=18): Network is unreachable: 216 time(s) sendto(2002:a00:2:1234:219:9dff:fe38:406d) (fd=18): Network is unreachable: 116 time(s) sendto(2002:a00:3:1234:8a25:2cff:fec2:c0ab) (fd=18): Network is unreachable: 4 time(s) sendto(2002:c0a8:f02:1234:219:9dff:fe37:2031) (fd=18): Network is unreachable: 56 time(s) sendto(2002:c0a8:f02:1234:219:9dff:fe5a:4e9d) (fd=18): Network is unreachable: 28 time(s) sendto(2002:c0a8:f02:1234:219:9dff:fe3d:1661) (fd=18): Network is unreachable: 32 time(s) sendto(2002:c0a8:104:1234:219:9dff:fe38:7cf) (fd=18): Network is unreachable: 144 time(s) sendto(2002:c0a8:f02:1234:219:9dff:fe89:8ee8) (fd=18): Network is unreachable: 12 time(s) sendto(2002:c0a8:f04:e472:219:9dff:fe0b:b983) (fd=18): Network is unreachable: 140 time(s) sendto(2002:c0a8:fe01:1234:219:9dff:fe8c:be78) (fd=18): Network is unreachable: 31 time(s) sendto(2002:c0a8:2:1234:219:9dff:fe3c:49a7) (fd=18): Network is unreachable: 88 time(s) sendto(2002:c0a8:3:1234:219:9dff:fe37:2dce) (fd=18): Network is unreachable: 44 time(s) sendto(2002:c0a8:c802:1234:219:9dff:fe0b:4b4c) (fd=18): Network is unreachable: 12 time(s) sendto(2002:c0a8:127:1234:219:9dff:fe0b:c5fb) (fd=18): Network is unreachable: 64 time(s) sendto(2002:c0a8:3:1234:8a25:2cff:fe57:cf5e) (fd=18): Network is unreachable: 4 time(s) sendto(2002:a01:aaf:1234:219:9dff:fe3c:c6fc) (fd=18): Network is unreachable: 82 time(s) sendto(2002:a00:3:1234:7a44:76ff:fe90:fa7d) (fd=18): Network is unreachable: 396 time(s) sendto(2002:c0a8:124:1234:219:9dff:fe41:dc7e) (fd=18): Network is unreachable: 60 time(s) sendto(2002:ac1b:230a:1234:219:9dff:fe3c:90f1) (fd=18): Network is unreachable: 336 time(s) sendto(2002:c0a8:10f:e472:7a44:76ff:fe91:6059) (fd=18): Network is unreachable: 34 time(s) sendto(2002:c0a8:3:e472:219:9dff:fe1d:9fb0) (fd=18): Network is unreachable: 52 time(s) sendto(2002:c0a8:265:1234:219:9dff:fe0b:1a47) (fd=18): Network is unreachable: 8 time(s) sendto(2002:a00:2:1234:7a44:76ff:fe91:54c9) (fd=18): Network is unreachable: 28 time(s) sendto(2002:c0a8:a:1234:7a44:76ff:fe90:e7c3) (fd=18): Network is unreachable: 4 time(s) sendto(2002:c0a8:2c1:1234:219:9dff:fe40:5dbc) (fd=18): Network is unreachable: 64 time(s) sendto(2002:a00:2:1234:219:9dff:fe49:1755) (fd=18): Network is unreachable: 180 time(s) sendto(2002:c0a8:1c:1234:224e:7fff:fed6:23d) (fd=18): Network is unreachable: 12 time(s) sendto(2002:c0a8:6a:1234:219:9dff:fe89:e952) (fd=18): Network is unreachable: 8 time(s) sendto(2002:c0a8:11b:1234:219:9dff:fe5c:3db4) (fd=18): Network is unreachable: 161 time(s) sendto(2002:c0a8:d:1234:219:9dff:fe0b:a2dd) (fd=18): Network is unreachable: 446 time(s) sendto(2002:c0a8:f04:1234:219:9dff:fe8c:a409) (fd=18): Network is unreachable: 92 time(s) sendto(2002:a00:2:1234:224e:7fff:fed5:b0fc) (fd=18): Network is unreachable: 36 time(s) sendto(2002:c0a8:11e:1234:219:9dff:fe37:f9eb) (fd=18): Network is unreachable: 284 time(s) [truncated] I tried a quick ping6 and got network unreachable. I also used a random website with a remote ip6 ping and got the same result. Is this a case of someone spoofing ipv6 UDP NTP packets? Are others seeing this? Thanks for your thoughts...
