Server is netbsd-3, client is -current. UDP also works.
The following are commands on the client:
# mount_nfs -T 2002:XXXX:XX6f:2:2a0:24XX:fe4e:ea84:/srv/nfs /mnt
% netstat -a -f inet6 | grep nfs =
[~]
tcp6 0 0 proton.1018 quanta.nfs ESTABLIS=
HED
% rpcinfo 2002:XXXX:XX6f:2:2a0:24XX:fe4e:ea84 | grep nfs =
[~]
100003 2 udp 0.0.0.0.8.1 nfs superuser
100003 3 udp 0.0.0.0.8.1 nfs superuser
100003 2 udp6 ::.8.1 nfs superuser
100003 3 udp6 ::.8.1 nfs superuser
100003 2 tcp 0.0.0.0.8.1 nfs superuser
100003 3 tcp 0.0.0.0.8.1 nfs superuser
100003 2 tcp6 ::.8.1 nfs superuser
100003 3 tcp6 ::.8.1 nfs superuser
% showmount -e 2002:XXXX:XX6f:2:2a0:24XX:fe4e:ea84
showmount: Can't do Exports rpc: RPC: Unknown host
The only thing that seems to be broken is showmount, both in netbsd-3
and -current.
