When you try use NFS on /var/log/messages you get:
svc: failed to register lockdv1 RPC service (errno 97).
This problem happen because NFS don’t deal with IPV6 stack.
To fix it with need to disable IPV6 on Kernel.
The better way to do that is on GRUB.
Edit /etc/default/grub
Put the line:
GRUB_CMDLINE_LINUX=”ipv6.disable=1″
Update GRUB:
sudo update-grub2
Cheers!
