Introduction to NFS Utilities
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.
Project Homepage: Unknown
Dependencies
Required
Optional for NFSv4 Support
Optional for GSS (RPC Security) Support
- Pkg-config
- libgssapi
- librpcsecgss
- MIT krb5
- SPKM-3 for Additional SPKM-3 Support
Creating the nobody/nogroup User/Group
groupadd -g 65533 nogroup &&
groupadd -g 65534 nobody &&
useradd -c "Nobody" -d /dev/null \
-u 65534 -g nobody -s /bin/false nobody
Non-Multilib
Compile the package:
./configure --prefix=/usr --sysconfdir=/etc \
--disable-nfsv4 --disable-gss &&
make
Install the package
make install
Multilib
This package does not install any libraries so only one installation is needed.
32Bit
Compile the package:
CC="gcc ${BUILD32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH32}" USE_ARCH=32 \
./configure --prefix=/usr --sysconfdir=/etc \
--disable-nfsv4 --disable-gss &&
make
Install the package
make install
N32
Compile the package:
CC="gcc ${BUILDN32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATHN32}" USE_ARCH=n32 \
./configure --prefix=/usr --sysconfdir=/etc \
--disable-nfsv4 --disable-gss &&
make
Install the package
make install
64Bit
Compile the package:
CC="gcc ${BUILD64}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH64}" USE_ARCH=64 \
./configure --prefix=/usr --sysconfdir=/etc \
--disable-nfsv4 --disable-gss &&
make
Install the package
make install
Configuring
Note
Make sure that your clocks are in sync. If the time differers by more then 5 minutes, you will not authenticate even with the correct password / key.
You must also have a working DNS & Reverse DNS Zones. If your FQDN for your host resolves to 127.0.0.1 Kerberos will not work properly either.Client
NFSv4
Make sure that you have your Kerberos KDC setup then add a client key, then export it to a temporary keytab:
kadmin.local -q "addprinc <fqdn of client>@<REALMNAME.COM>" kadmin.local -q "ktadd -e des-cbc-crc:normal -k temp.keytab nfs/<fqdn of client>@<REALMNAME.COM>"
Now securely move temp.keytab to /etc/nfs4.keytab on the client.
Bootscript
Install the init script from the bootscripts package:
make install-nfs-client
/etc/fstab
Below are 2 example entries in /etc/fstab for a nfs mounted /home and /usr.
<server-name>:/home /home nfs rw,_netdev,rsize=8192,wsize=8192 0 0 <server-name>:/usr /usr nfs ro,_netdev,rsize=8192 0 0
<server-name> in the above example is an ip address or a hostname.
Server
NFSv4
Make sure that you have your Kerberos KDC setup then add a client key, then export it to a temporary keytab:
kadmin.local -q "addprinc <fqdn of client>@<REALMNAME.COM>" kadmin.local -q "ktadd -e des-cbc-crc:normal -k temp.keytab nfs/<fqdn of client>@<REALMNAME.COM>"
Now securely move temp.keytab to /etc/nfs4.keytab on the server.
Bootscript
Install the init script from the bootscripts package:
make install-nfs-server
And configure it:
cat > /etc/sysconfig/nfs-server << "EOF" PORT="2049" PROCESSES="8" QUOTAS="no" KILLDELAY="10" EOF
Server Configuration
/etc/exports contains the exported directories on NFS servers. The "NFS HowTo", http://nfs.sourceforge.net/nfs-howto/. contains information on how to configure the servers and clients. 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)
