c. Install the appropriate file.
These files can be installed on an active system.
However, there will be a delay to clients attempting
to mount NFS filesystems from this server.
Stop the rpc.mountd process
# ps -ef|grep rpc.mountd
# kill <PID>
-or-
Stop the NFS server
# /sbin/init.d/nfs.server stop
cd to the directory containing the new rpc.mountd.
HP-UX B.11.00
=============
chown bin:bin rpc.mountd.11.00
chmod 544 rpc.mountd.11.00
mv /usr/sbin/rpc.mountd /usr/sbin/rpc.mountd.orig
mv rpc.mountd.11.00 /usr/sbin/rpc.mountd
HP-UX B.11.11

To -gain access- to the Security Patch Matrix, select
the link for "The Security Bulletins Archive". (near the
bottom of the page) Once in the archive the third link is
to the current Security Patch Matrix. Updated daily, this
matrix categorizes security patches by platform/OS release,
and by bulletin topic. Security Patch Check completely
automates the process of reviewing the patch matrix for
11.XX systems. Please note that installing the patches
listed in the Security Patch Matrix will completely
implement a security bulletin _only_ if the MANUAL ACTIONS
field specifies "No."
The Security Patch Check tool can verify that a security
bulletin has been implemented on HP-UX 11.XX systems providing
that the fix is completely implemented in a patch with no
manual actions required. The Security Patch Check tool cannot
verify fixes implemented via a product upgrade.
