The NFS Utilities package contains the userspace server and client tools necessary to use the kernel's NFS abilities. NFS is a protocol that allows sharing file systems over the network.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/nfs-utils
Enable the following options in the kernel configuration and recompile the kernel if necessary:
File systems:
Network File Systems:
NFS File System Support: M or Y
NFS Server Support: M or Y
Select the appropriate sub-options that appear when the above options are selected.
Before you compile the program, ensure that the nobody user and nogroup group have been created. You can add them by running the following commands as the root user:
groupadd -g 99 nogroup &&
useradd -c "Unprivileged Nobody" -d /dev/null -g nogroup \
-s /bin/false -u 99 nobody
![[Note]](../images/note.png)
The classic uid and gid values are 65534 which is also -2 when interpreted as a signed 16-bit number. These values impact other files on some filesystems that do not have support for sparse files. The nobody and nogroup values are relatively arbitrary. The impact on a server is nil if the exports file is configured correctly. If it is misconfigured, an ls -l or ps listing will show a uid or gid number of 65534 instead of a name. The client uses nobody only as the user running rpc.statd.
Install NFS Utilities by running the following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--disable-nfsv4 \
--disable-gss &&
make
This package does not come with a test suite.
Now, as the root user:
If your /usr directory is NFS mounted, you should install the executables in /sbin by passing an additional parameter --sbindir=/sbin to the above ./configure command.
make install
--disable-nfsv4: Disables support for NFS version 4.
--disable-gss: Disables support for RPCSEC GSS (RPC Security).
--with-tcp-wrappers: Use this option to enable tcpwrappers support.
/etc/exports contains the exported directories on NFS servers. Refer to the exports.5 manual page for the syntax of this file. Also refer to the "NFS HowTo" available at http://nfs.sourceforge.net/nfs-howto/ for information on how to configure the servers and clients in a secure manner. For example, for sharing the /home directory over the local network, the following line may be added:
/home <192.168.0.0/255.255.255.0>(rw,subtree_check,anonuid=99,anongid=99)
Install the /etc/rc.d/init.d/nfs-server init script included in the blfs-bootscripts-20060910 package to start the server at boot.
make install-nfs-server
Now create the /etc/sysconfig/nfs-server configuration file:
cat > /etc/sysconfig/nfs-server << "EOF" PORT="2049" PROCESSES="8" QUOTAS="no" KILLDELAY="10" EOF
/etc/fstab contains the directories that are to be mounted on the client. Alternately the partitions can be mounted by using the mount command with the proper options. To mount the /home and /usr partitions, add the following to the /etc/fstab:
<server-name>:/home /home nfs rw,_netdev,rsize=8192,wsize=8192 0 0 <server-name>:/usr /usr nfs ro,_netdev,rsize=8192 0 0
Install the /etc/rc.d/init.d/nfs-client init script included in the blfs-bootscripts-20060910 package to start the client services at boot.
make install-nfs-client
To automatically mount nfs filesystems, clients will also need to install the netfs bootscript as described in Configuring for Network Filesystems.
