filesystem. The decision of sharing directories by an NFS server is driven by the
applications running on NFS clients that require access to those directories.
2. Specify access restrictions and security modes for the shared directories. For
example, you can use Kerberos (a security product) that is already configured on
your system to specify access restrictions and security modes for the NFS shared
directories.
NFS Configuration Files and Daemons
This section describes the NFS configuration files and daemons.
Configuration Files
Table 2-1 describes the NFS configuration files and their functions.
Table 2-1 NFS Server Configuration Files
FunctionFile Name
Contains the variables read by the start-up scripts of the NFS
subsystem.
/etc/rc.config.d/nfsconf
Contains the PC NFS configuration information.
/etc/pcnfsd.conf
Contains the parameters to set the default behavior of various
NFS commands and daemons.
/etc/default/nfs
Contains the share commands that are executed when the NFS
server subsystem starts.
/etc/dfs/dfstab
Contains the distributed filesystem types. The default filesystem
is NFS.
/etc/dfs/fstypes
Contains the valid and supported NFS security modes.
/etc/nfssec.conf
Contains the system record of shared filesystems.
/etc/dfs/sharetab
Contains all the entries for hosts that have mounted filesystems
from any system.
/etc/rmtab
Daemons
Table 2-2 describes the NFS server daemons.
Table 2-2 NFS Server Daemons
FunctionDaemon Name
Answers requests for NFS access information and filesystem mount requests.
The rpc.mountd daemon reads the /etc/dfs/sharetab file to determine
which filesystems are available for mounting and by which remote systems.
rpc.mountd
Handles client filesystem requests. By default, nfsd starts over TCP, TCP6,
UDP, and UDP6 transports.
