By default F27 uses NFSv4. The access is far more restrictive. If you're
NFS mounting a filesystem as a normal user on the client, then you have
to make sure that user has the same UID and GID on the server and has
access to that exported directory.

If you're mounting it as root on the client (as seems to be true by the
"#" in the example command), make sure you add "no_root_squash" to the
export at the server:

        /home/public    192.168.1.0/24(rw,no_root_squash)

Otherwise the server will try to demote the root user down to the
anonymous user, who probably doesn't have R/W access to /home/public
(or whatever export you've specified).

Make sense?
