Projects: NFS Version 4 Open Source Reference Implementation
|
|
|
Introduction
From rfc3530:
The Network File System (NFS) version 4 is a distributed filesystem
protocol which owes heritage to NFS protocol version 2, RFC 1094, and
version 3, RFC 1813. Unlike earlier versions, the NFS version 4
protocol supports traditional file access while integrating support
for file locking and the mount protocol. In addition, support for
strong security (and its negotiation), compound operations, client
caching, and internationalization have been added. Of course,
attention has been applied to making NFS version 4 operate well in an
Internet environment.
We are developing an implementation of NFSv4 and NFSv4.1 for Linux.

We have released the combined BSD client.
This client currently runs on Darwin (Mac OS X) and FreeBSD.
It includes gss support.
It is in a very preliminary condition and we are unable to offer any support for it.

As of the 5.2 release our NFSV4 client is part of the FreeBSD source tree. See the
FreeBSD web site
for information on obtaining kernel source.

New FreeBSD and Linux code is available (see below). Future development on
Linux will be on 2.6, not 2.4.

- IETF comments for draft-adamson-rfc2847-bis-01 These are the comments we received from IETF after are two submissions of the draft. In our first submission, the wrong document was reviewed. However, most of the comments were useful. We have updated the draft based on the received comments. We also commented each of the points in the review as to how we address it (or not yet).
