writing to MAC files from a Linux VM

I'm trying to copy files from a Linux directory to a MAC directory.

I read nfs was the way to go, I downloaded the nfs manager for MAC, and did not choose to
make the exported directory readonly (did not check the box).

And on the Linux side, in my /etc/fstab I have the following:
192.168.x.x:/macdirectory /mnt/apple nfs defaults 0 0

I can read the files in the macdirectory fine, but can not write to it.

Is there another way to access the files other than nfs? (prefer not use ftp - but if I have to.....)
