LAN Interface ping problem
-
you shouldn't be getting a /128 on your pi… The smallest prefix with ipv6 is /64.. And its not just linux that works that way its every OS there is that can work with IPv6..
anything other /64 is going to break all kinds of shit from working correctly..
I dusted off my raspberry pi over the weekend, and installed latest NOOBS + raspbian, sure enough it comes up with /128 in addition to /64.
The /128 is the address assigned by the DHCP server; the /64, I guess it is deciding thru SLAAC on its own because of RA. I have some android clients on the network, so need SLAAC too.
radvd on pfsense 2.2.4 is set to Assisted, with the RA Subnet set to WWWW:XXXX:YYYY:ZZZZ::/64
Win2K8 DHCP server is handing out IPs in WWWW:XXXX:YYYY:ZZZZ::/64
Resolv.conf on PI ends up with Domain Controller IPv4+IPv6 IP as well as pfSense IPv6 IP, not ideal since it doesn't have any knowledge of the domain. Strange that it ended up with the pfSense IPv6 IP because the DNS Servers entry is blank in the RA config tab.eth0 Link encap:Ethernet HWaddr b8:27:eb:35:53:31 inet addr:10.2.95.18 Bcast:10.2.95.255 Mask:255.255.254.0 inet6 addr: WWWW:XXXX:YYYY:ZZZZ:fcef:f7d6:12c3:f393/64 Scope:Global inet6 addr: fe80::bd6c:2ed5:a452:1eff/64 Scope:Link inet6 addr: WWWW:XXXX:YYYY:ZZZZ:c439:ca13:15f5:31a9/128 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:80378 errors:0 dropped:5856 overruns:0 frame:0 TX packets:4106 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6121679 (5.8 MiB) TX bytes:662612 (647.0 KiB) wlan0 Link encap:Ethernet HWaddr 34:08:04:a0:5d:3d inet addr:10.2.95.20 Bcast:10.2.95.255 Mask:255.255.254.0 inet6 addr: WWWW:XXXX:YYYY:ZZZZ:927a:28a4:a3e3:73f8/128 Scope:Global inet6 addr: fe80::b69e:3850:a1d0:6935/64 Scope:Link inet6 addr: WWWW:XXXX:YYYY:ZZZZ:d9d4:1377:f075:8c05/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:315611 errors:0 dropped:17236 overruns:0 frame:0 TX packets:325 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:121355585 (115.7 MiB) TX bytes:63491 (62.0 KiB)
