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.
