I've installed rdnssd The host has ipv6 enabled in /etc/network/interfaces and it's acquiring an IPv6 address via RA in addition to having a static IPv6 Address
rdnssd is running but nothing is changing in /etc/resolv.conf or /var/run/rdnssd/resolv.conf Any suggestions? root@orangepi-r1:~# cat /etc/network/interfaces source /etc/network/interfaces.d/* auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.1/24 auto enxc0742bffdceb iface enxc0742bffdceb inet dhcp iface enxc0742bffdceb inet6 static address 2403:5800:c101:b700:beef::face/64 # use SLAAC to get global IPv6 address from the router autoconf 1 accept_ra 1 privext 2 cat /var/run/rdnssd/resolv.conf search lan bronzemail.com cat /etc/resolv.conf nameserver 10.31.40.4 nameserver 10.31.40.5 search lan bronzemail.com root@orangepi-r1:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 02:42:7d:73:5a:21 brd ff:ff:ff:ff:ff:ff inet 192.168.0.1/24 brd 192.168.0.255 scope global eth0 valid_lft forever preferred_lft forever 3: enxc0742bffdceb: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether c0:74:2b:ff:dc:eb brd ff:ff:ff:ff:ff:ff inet 10.31.40.242/24 brd 10.31.40.255 scope global dynamic enxc0742bffdceb valid_lft 84677sec preferred_lft 84677sec inet6 2403:5800:c101:b700:b99c:4896:34af:8926/64 scope global temporary dynamic valid_lft 3012sec preferred_lft 2011sec inet6 2403:5800:c101:b700:c274:2bff:feff:dceb/64 scope global dynamic mngtmpaddr valid_lft 3012sec preferred_lft 2011sec inet6 2403:5800:c101:b700:beef::face/64 scope global valid_lft forever preferred_lft forever inet6 fe80::c274:2bff:feff:dceb/64 scope link valid_lft forever preferred_lft forever 4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 44:b2:95:fc:5f:74 brd ff:ff:ff:ff:ff:ff root@orangepi-r1:~# route -n6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2403:5800:c101:b700::/64 :: U 256 2 0 enxc0742bffdceb fe80::/64 :: U 256 1 0 enxc0742bffdceb ::/0 fe80::fca5:6fff:fe75:6129 UGDAe 1024 4 0 enxc0742bffdceb ::1/128 :: Un 0 6 0 lo 2403:5800:c101:b700:b99c:4896:34af:8926/128 :: Un 0 3 0 enxc0742bffdceb 2403:5800:c101:b700:beef::face/128 :: Un 0 5 0 enxc0742bffdceb 2403:5800:c101:b700:c274:2bff:feff:dceb/128 :: Un 0 2 0 enxc0742bffdceb fe80::c274:2bff:feff:dceb/128 :: Un 0 3 0 enxc0742bffdceb ff00::/8 :: U 256 6 0 enxc0742bffdceb ::/0 :: !n -1 1 0 lo root@orangepi-r1:~# lsof | grep rdnssd rdnssd 977 root cwd DIR 179,1 4096 2 / rdnssd 977 root rtd DIR 179,1 4096 2 / rdnssd 977 root txt REG 179,1 17880 1188 /usr/sbin/rdnssd rdnssd 977 root mem REG 179,1 113596 6997 /usr/lib/arm-linux-gnueabihf/libpthread-2.31.so rdnssd 977 root mem REG 179,1 973416 6819 /usr/lib/arm-linux-gnueabihf/libc-2.31.so rdnssd 977 root mem REG 179,1 22488 7004 /usr/lib/arm-linux-gnueabihf/librt-2.31.so rdnssd 977 root mem REG 179,1 110012 6718 /usr/lib/arm-linux-gnueabihf/ld-2.31.so rdnssd 977 root 0r CHR 1,3 0t0 3 /dev/null rdnssd 977 root 1w CHR 1,3 0t0 3 /dev/null rdnssd 977 root 2w CHR 1,3 0t0 3 /dev/null rdnssd 977 root 3wW REG 0,23 3 379 /run/rdnssd.pid rdnssd 977 root 4r FIFO 0,12 0t0 8479 pipe rdnssd 978 rdnssd cwd DIR 179,1 4096 2 / rdnssd 978 rdnssd rtd DIR 179,1 4096 2 / rdnssd 978 rdnssd txt REG 179,1 17880 1188 /usr/sbin/rdnssd rdnssd 978 rdnssd mem REG 179,1 30344 6966 /usr/lib/arm-linux-gnueabihf/libnss_files-2.31.so rdnssd 978 rdnssd mem REG 179,1 113596 6997 /usr/lib/arm-linux-gnueabihf/libpthread-2.31.so rdnssd 978 rdnssd mem REG 179,1 973416 6819 /usr/lib/arm-linux-gnueabihf/libc-2.31.so rdnssd 978 rdnssd mem REG 179,1 22488 7004 /usr/lib/arm-linux-gnueabihf/librt-2.31.so rdnssd 978 rdnssd mem REG 179,1 110012 6718 /usr/lib/arm-linux-gnueabihf/ld-2.31.so rdnssd 978 rdnssd 0r CHR 1,3 0t0 3 /dev/null rdnssd 978 rdnssd 1w CHR 1,3 0t0 3 /dev/null rdnssd 978 rdnssd 2w CHR 1,3 0t0 3 /dev/null rdnssd 978 rdnssd 3w REG 0,23 3 379 /run/rdnssd.pid rdnssd 978 rdnssd 4u netlink 0t0 499 ROUTE rdnssd 978 rdnssd 5w FIFO 0,12 0t0 8479 pipe -- Jeremy
