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":

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
