Patch Name:  PHNE_3690

Patch Description: s300_400 9.X nsswitch supplement patch for nslookup(1)

        Provides DNS fallback -- configurable order of hostname/address
        lookup.

This patch MUST HAVE PHCO_3875 in order for it to work.

Otherwise, without the new library, the nslookup program
will fail to function. As well as a new nslookup this patch
provides documentation and configuration files for using
the new name service switch feature. This patch and
PHCO_3875 allows an administrator to configure the order
of name services and the criteria under which they will be
tried.

For more information see the man pages switch(4),
nslookup(1) and gethostent(3N). A postscript copy
of the switch documentation is located in /usr/doc.

At this time, the following commands will not use the nsswitch
functionality in this patch:  /etc/route, /etc/ifconfig,
/etc/mount, /etc/update and /etc/updist.  These commands are
statically linked which means they use the archive library from
compile time.  Therefore, these commands (or any statically linked
program) will not use the nsswitch functionality unless recompiled
with the new library.  (Other dynamically linked commands use
libc.sl, therefore they will use the new nsswitch functionality.)"

---------------------------------------------------------------------------
After getting the patch onto your machine, unshar the patch (sh PHNE_3690).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: /tmp/PHNE_3690.updt"
   (this assumes that you are in the /tmp directory where PHNE_3690.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".
6) From here on follow the standard directions for update.

The customized script that update runs will move the original software
to /system/PHNE_3690/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHNE_3690.text file to /system/PHNE_3690 to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example the
following will create a copy of the patch that update can read:
dd if=PHNE_3690.updt of=/dev/rmt/0m bs=2048
