Hi, Error -13 is EACCESS (permission denied). Can you check the permissions, probably /home/hylee is not readable + executable by 'other'. I think the r+x permission is needed for the NFS server to be able to offer the underlying directory as a share. If changing the permission is unaccaptable you can always move the root filesystem. We tend to put in under /tftpboot/remote_fs/<target_name> and modify the exports file to export /tftpboot. As /tftpboot is 'public' from the TFTP server it is not much of a security risk.
