Just a note about some info I found out from AUX support. Seems A/UX 2.0
uses NFS version 2.0. SunOS 4.0.3 uses NFS 3.0. There have been several
reports of compatibility problems between the two from users. I have
seen problems with the DeskTop Manager of NFS mounted file systems on
a Sun/4 110. At this time, Apple does not have a work around.
P.S. I found the AUX support group to be very helpful and friendly.
I hope that this level of support continues...

I had some problems with NFS. The symptom was that ld was creating bad file and known good source code did not work. After some time, this is the responce I got from Apple. You asked about the problem where the loader can write a block of zeroes to your output file when you are linking across NFS. Apparently, the problem is caused by race conditions between the multiple processes you get to do the file I/O. We are currently looking at a fix for this. A short term solution would be to run without biod daemons, which are the asynchronous block I/O daemons. Without these, you will get serial I/O, thus eliminating the race condition. And sure enough, that took care of my problems.

At this time, Apple does not have a work around. More details, please. I don't know what you mean by "NFS 2.0" and "NFS 3.0". Both A/UX (all releases) and SunOS 4 (4.0,4.1) use version 2 of the NFS protocol as reported by rpcinfo. The include files under A/UX 2.0 have lines saying /* NFSSRC @(#)vnode.h 2.1 86/04/11 */ On my SunOS 4.1 machine the corresponding comment is /* @(#)vnode.h 2.43 89/05/16 SMI */ On my VAX machine, for which we bought the NFS 3.0 source licence, having upgraded from the NFS 2.0 source, it says /* NFSSRC @(#)vnode.h 2.1 86/04/11 */ /* @(#)vnode.h 1.1 86/02/03 SMI */ The VAX source matches the NFS implementation in SunOS 3.0, which lacked facilities such as the kernel routine wakeup_one which appeared in SunOS 3.2 and is definitely present in A/UX 1.0 onwards. Looking at the SCCS ident in the nfsd program (as another clue), we see A/UX 2.0: Copyright (c) 1983-87 Sun Microsystems Inc., All Rights Reserved. {Apple version 1.4 89/10/09 21:00:37} SunOS 4.1: nfsd.c 1.10 88/08/04 Copyr 1985 Sun Micro VAX (NFS 3.0): nfsd.c 1.1 86/02/03 Copyr 1985 Sun Micro From all this evidence (plus trying to get an up-to-date NFS source licence) I conclude that A/UX is using what I would refer to as NFS 3.2, and that SunOS 4.1 is using what Sun now call ONC/NFS 4.0. I would be interested to know what the "compatibility problems" are supposed to be, especially since there is no mention of an such problems in the Sun customer distributed buglist. -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)
