Summary of problem:
For a few months now our PCs have been slow to initialize and I just found
out that they have also not been able to mount file systems using the
/mustshare option. All was fine before I installed all recommended SunOS
4.1.3 security patches on the servers. We are using PC-NFS versions 5.0
and 5.1. As a consequence we have had several cases where PC based
databases have trashed their db files located on our Sun file servers.
The pcnfsd and NIS server is a SPARC10 Model 51 running SunOS 4.1.3, again
with all Sun Security patches installed. I also tried installing the lockd
patch from Sun but this didn't help. When I try to mount a file system
with /ms I get the error:
NFS152F: Cannot contact the Network Lock Manager on the server.
The answer came from chris@speckle.ncsl.nist.gov (Chris Schanzle):
Chris said the problem is with the libc jumbo patch and that Sun had a
'patched' NET.EXE for pcnfs version 5.0. I contacted Sun, received the
patched NET.EXE and the option /mustshare works fine now. The Sun tech
support guy said that PCNFS version 5.1 will be fixed with the release of
5.1a which if it isn't out already it will hit the streets any day now.
Chris had to back out the patches on the Sun server himself to
determine what broke PCNFS ... Sun tech support apparently didn't
believe that there was a problem with pcnfs.
