[tlug] Permissions on NFS share

[Dave M G <dave@example.com>]

TLUG,

I had to reinstall Ubuntu on a machine in my home network, and so I'm 
trying to re-establish it's network connection to my one other machine.

I've been through this before, so I thought I knew what I was doing. In 
any case, I used this web page as a reference to make sure I was on the 
right track.

In the server /etc/exports file, I've got:
/home/media media-centre(rw,no_root_squash)

On the client /etc/fstab, I've got:
192.168.0.4:/home/media /home/dave/media nfs rw 0 0

On the client, when I try to mount the network drive, I get the 
following error.
$ sudo mount -a
mount.nfs: access denied by server while mounting 192.168.0.4:/home/media

I set /home/media to be 777 permissions to be sure it wasn't a 
permissions error. And I turned off the firewall. But it's still 
returning the exact same error.

What other permission could be involved?

Thanks for any advice.
