NFS Utilities-1.0.6

Introduction to nfs-utils

The nfs-utils 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.

Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel if neccessary: 

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.

Installation of nfs-utils

Before you compile the program, you need to be sure the "nobody" user and "nogroup" group are available. You can add these with the following commands: 

groupadd -g 65534 nogroup &&
useradd -c nobody -d /home -g nogroup -s /bin/bash -u 65534 nobody

Install nfs-utils by running the following commands: 

./configure --prefix=/usr --sysconfdir=/etc &&
make &&
make install
[Note]

Note

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.

Configuring nfs-utils

Server Configutation

/etc/exports contains the exported directories on NFS servers. Refer to the exports manual page for the syntax of this file. Also refer to the NFS HowTo available at http://nfs.sourceforge.net/nfs-howto/ 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 192.168.0.0/255.255.0.0(rw)

Install the /etc/rc.d/init.d/nfs-server init script included in the blfs-bootscripts-5.1 package to start the server at boot. 

make install-nfs-server

Client Configutation

/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 partition, add the following to the /etc/fstab: 

<server-name>:/home /home nfs rw 0 0

Install the /etc/rc.d/init.d/nfs-client init script included in the blfs-bootscripts-5.1 package to start the client services at boot. 

make install-nfs-client
