SYNOPSIS:    NFS exported file systems won't mount

OS RELEASE:  2.x

PRODUCT:     Solaris 

KEYWORDS:    mount NFS permissions


SYMPTOMS: 

Exported files systems from older Unix systems won't mount   


DESCRIPTION:

NFS exported file system won't mount.  "Snoop" is untilized to trace the
protocol transaction messages between the Solaris system and the foreign
NFS host.  The messages show all the correct information flowing between
the machines.  A "permission denied" message indicates the mountd is
unhappy.  The NFS file permissions are wide open and root is not
involved so no special permissions are required. 


SOLUTION:

One of the more obscure requirements of NFS is the all host IP addresses
must be "known" by the NFS host.  This is accomplished by a simple entry
defining the host in the /etc/hosts file.  Some systems have options to
relax mountd known host requirements.  Sunsoft IUS has the "-u" option.
