export invalid option

[1putt]

Im trying to install redhat from a cdrom on my mandrake box.
my exports file has the following /dev/cdrom <redhat ip#>(ro).
but when i run exportfs i get an error message invalid option.

any suggestions
Thanks

Did you try mounting the CDROM on the Mandrake machine first, then exporting it with NFS? In otherwords, as root, do:

mount /dev/cdrom /mnt/cdrom

Change your exports file line to:

/mnt/cdrom <rh ip#>(ro)

Then do the exportfs -a
