NFS public filehandes?

Can HPUX 11.23 NFSv3 use Public filehandles?

Hi Mark,

11.23 has NFS version 3 and Public file handles are supported only in NFS4. Check this for more information : http://www.zvon.org/tmRFC/RFC3530/Output/chapter4.html

This suggests that NFS versions 2 and 3 had public filehandle support?
Is it just HPUX's version that won't support Public filehandles until version 4?

"Since NFS version 2 and version 3 have different filehandle formats, the public filehandle is defined differently for each.

The public filehandle is a zero filehandle. For NFS version 2 this is a filehandle with 32 zero octets. A version 3 public filehandle
has zero length."

"5.2 NFS Version 3 Public Filehandle

A version 3 filehandle is defined in RFC 1813 as a variable length
opaque value occupying up to 64 octets. The length of the filehandle
is indicated by an integer value contained in a 4 octet value which
describes the number of valid octets that follow. A version 3 public
filehandle has a length of zero."

Hi Mark,

I believe the public filehandles you're referring to were added as part of the WebNFS product that Sun launched a few years ago. Most of that functionality has been added into the NFS V4 protocol.

As of 11.23, HP-UX does not support WebNFS, nor do we support the concept of a public filehandle. We are planning on adding support for WebNFS public filehandles and NFS V4 on HP-UX 11.31 (aka 11i v3).

Hope this helps,

Dave
