NFSv4
NFSv4 is a new generation of network filesystems. It is designed to be run over internet, and it has these capabilities :
Features
Security
NFSv4 is can be secured via one of three types of security "flavors":
- Kerberos
- SPKM
- LIPKEY
For each flavor, there may be multiple implementations. For instance, with Kerberos there are both "MIT Kerberos", and "Heimdal Kerberos".
Kerberos and NFSv4
Setup instructions for kerberos/NFSv4 are here
Network optimisations
Interoperability
IPv6 support for the client
Here is a short description to explain how to have an IPv6 ready client for NFSv2,v3 and v4. For further information about the IPv6 support design, please look here
TI-RPC library
The ti-rpc library is designed to replace sunrpc library. It is necessary to do Remote Procedures Calls regardless of the transport used.
Download the tirpc tarball: libtirpc-0.1.7.tar.bz2
Build and install:
> ./configure > make > make install
Kernel patches
Dowload the cumulative patch: linux-2.6.11-ALL.patch
In the kernel source directory:
> patch -p1 < linux-2.6.11-NFS-IPv6-client.patch
User part patches
Download nfs-utils tarball with IPv6 support included: util-linux-2.12-3-IPv6.tar.bz2
or
Download the util-linux-2.12 tarball: util-linux-2.12.tar.gz
Download and apply the util-linux-2.12-CITI_NFS4_ALL-3 patchset util-linux-2.12-CITI_NFS4_ALL-3.dif
In util-linux-2.12 directory:
> patch -p1 < util-linux-2.12-CITI_NFS4_ALL-3.dif
Download and apply cumulative patch for util-linux-2.12 : util-linux-2.12-IPv6.patch
In util-linux-2.12 directory:
> patch -p1 < util-linux-2.12-IPv6.patch
