Following the written documentation for using NFS in RH 6-1 doesn't work. Any attempt to mount an exported file system returns the error message mount: RPC: Program not registered Other programs, such as showmount -e, return similar messages. Cannot do anything with /etc/rc.d/init.d/nfs because there is no file named nfs in that directory. Is there some package I need to install to use nfs? This happens on machines where I've installed Linux as a Gnome Workstation as well as a KDE workstation.
The file /etc/rc.d/init.d/nfs is in the knfsd package. Make sure that you have that (and the knfsd-clients) package(s) installed. You will also have to make sure that the daemons are started in the correct order (a reboot will insure that).
