The nfs server does not allow any client except the local host to mount a nfs share when configured as follows: /etc/exports: /export/hostname1 *.domain.org /mnt/cdrom *.domain.org /etc/nsswitch.conf: hosts: dns nis [NOTFOUND=return] files It should allow mounts from clients that are in the .domain.org DNS domain. It does not allow any mounts. If I remove the restriction on DNS domain all clients may mount the NFS shares.
Dave, can you verify this? I doubt it... Make sure you use knfsd.
I cannot reproduce this problem.
