TITLE:  NFS Gateway for NW60 file corruption fix
TID #:  2970820
README FOR:  nfsgy60c.exe

NOVELL PRODUCTS and VERSIONS:

ABSTRACT:

The enclosed update corrects a file corruption problem encountered when writing
files through NFS Gateway to a remote NFS Server (usually Unix or Linux), while
using NFS protocol 2.  This download is only for NFS Gateway for NetWare 6.0. 
In order to use this update, NFS Gateway must already be updated to Support
Pack 1.  NetWare 6.0 must already be updated to Support Pack 5.

The ONLY change between NFSGY60B.EXE and NFSGY60C.exe is that C provides an
additional, alternate copy of NFSGY.NLM that can be used with NSS update
NW6NSS5B.EXE or NW6NSS5C.EXE.  The code in each NLM is the same other than the
header files used in compiling the NLMs.

Due to other NFS Gateway write problems that can occur, it is also recommended
to use updates PKER151W.EXE and TCP610JB.EXE (or newer).

This download was rebuilt on June 23, 2005, to change its status from Beta to
Full Release, and to make minor updates to this readme.  Only the readme was
changed.

INSTALLATION INSTRUCTIONS:

1.  Insure NetWare 6.0 SP5 is installed, as well as NFS Gateway SP1 for NetWare
6.0.

2.  To prevent other file corruption issues, install PKER151W.WXE and
TCP610JB.EXE (or newer).

3.  If the server was not been rebooted after the last OS support pack or NSS
update, reboot now.  (If the instructions for the updates in step 2 were
followed, the server will have been rebooted after TCP610JB.EXE was installed. 
The reboot during step 2 or step 3 should be the only reboot needed while
following these instructions.)

4.  Rename SYS:SYSTEM\NFSGY.NLM to SYS:SYSTEM\NFSGY.SP1 (or any desired name).

5.  Conditional:  At the console prompt, give the command "NSS MODULES".  If
the "Snap Date" for NSS is 04510, copy the NFSGY.NLM provided in
nfsgy60c\nss5or5a to SYS:SYSTEM.  If the "Snap Date" is 04A08, copy the
NFSGY.NLM provided in nfsgy60c\nss5BorC to SYS:SYSTEM.

If any other NSS snap date is shown, neither of these NLMs will not load with
that version of NSS.  You can find the expected NSS files in NW 6.0 SP5,
NW6NSS5A.EXE, NW6NSS5B.EXE, or NW6NSS5C.EXE.

6.  At the server console, execute GYSTOP and GYSTART.

ISSUE: 

While writing files through NFS Gateway to a remote NFS Server (usually Unix or
Linux) using NFS protocol 2, small blocks of data may not get sent.  The blocks
are less than or equal to 4096 bytes in size, and once the first missing block
occurs, another will occur every 64K later in the file.  This problem does not
occur when using NFS protocol 3.

The other updates (PKER151W.EXE and TCP610J.EXE) are recommended to solve
packet fragmentation issues which can effect whether files are successfully
written to the remote NFS Server.  Those fragmentation issues effect both NFS
protovol v2 and v3.
