I naively > assume you have some contacts or a mailinglist you could use for that. Not sure what you are asking, but... The only other client I am familiar with is the Linux one. It does NFSv4, then NFSv3 (I think they have dropped NFSv2 support). Linux also does handle NFSv4 root file systems. The other clients I know of (VMware and Windows) do not paticipate in the IETF Working group's interoperability testing, unfortunately. (And I have no contact with either of these groups.) rick Bye, Alexander. -- http://www.Leidinger.net Alexander@Leidinger.net: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org netchild@FreeBSD.org : PGP 0x8F31830F9F2772BFhome | help
