First verify that it is shared correctly.
On pc09:
      showmount -e fedoraserver

That command should show you any files systems you can mount.

Next, let the client machine figure it out for himself what the server 
wants:
On pc09:
      mount fedoraserver:/home/mydir /home/jonh/server-mydir

You should not need any other options.

The structure of the source is like a URL, mount knows it is NFS just by 
the format of the source, ie: server:/dir

Good Luck!
