I ran into a problem using the tools for z/OS MVSNFS. IBM NFS support
apparently does not considered Linux a supported platform for the z/OS NFS
tools. However, I was able to get IBM to document the fix in apar II13061
as follows:
.
.
.
The instructions appear to not work on the S390 LINUX platform,
but the provided examples are from two customers with different
LINUX products being applied as Linux clients on the z-series.
.
This customer made the following changes for altering the
NFSTARB code using Red Hat 7.2 which allowed the 'make'
process to work in their case.
.
Making the following changes to gfsawlin.c and gfsawlou.c
allowed the 'make' to work :
.
CHANGING :
.
#ifdef MVS /[EMAIL PROTECTED]
#pragma comment(copyright,"GFSCWLOUHDZ11TC ")
#pragma options(RENT)
#pragma strings(readonly)
#pragma csect(CODE,"GFSCWLOU")
.
#include
#include
#include "gfscwmnt.h"
#else
#include
#include "gfsawmnt.h"
#endif
.
TO :
.
#include <<<<<<<
/*#include */ <<<<<< <<<<<<<
/*#include */ <<<<<<
#include "gfsawmnt.h"
#endif
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Then in gfsawlin.c Change the following lines in the
scramble(p) routine (about line#534) to compile with out
errors.
.
#ifdef MVS
.
*p = (*p ^ zchar); //<<<< SUBMITTER: TO MESSAGE CIRCUMVENTION:
CODES: RTN SRLS: MACROS: MODULES x COMMENTS: FIX: TEMPORARY CONCLUSION:
PROBLEM SUMMARY: LOCAL #endif character XOR ?^? <<<
I have created an RPM for the z/OS NFS tools if anyone is interested (use
at own risk). It was built from z/OS Version 1.5 NFS sources under SLES 8,
SP03.

The z/OS NFS server uses the security system you've configured on z/OS
to authenticate userid/pwd info passed by mvslogin, same as any other
z/OS app.

The source is included with the z/OS NFS feature. See the NFS server
configuration documentation for the location. When you compile it on
Linux, follow the process for AIX (since you don't say which version of
z/OS you're running, some of the older versions didn't have a Linux
build target in the makefile. The AIX one works for both.).
Before you do this, make certain that the UIDs (the numeric uid values;
don't care about the userid) you use on Linux and the POSIX UIDs you use
on z/OS match. Even with the additional identification mvslogin
provides, you want this as a general rule whenever NFS is involved.
