Or replace your shared libc with one that has the resolver routines enabled.

Hi Everyone.

The previous has been said very often before, but there are still many
SUN-system-administrators, who are unaware of this fact. I myself replied
many times on similar questions on the net (comp.sys.sun and alt.sys.sun).
I think it is time to post my digest of this subject here and I think that
it should be part of the FAQ-list (if there is any...).
Here it goes. Thanks to all who contributed to this digest.

Hello,

This is a mail to a few people who asked me for more info about the SunOS
shared libc with DNS-resolver. I apologize for not sending personal mail,
but this saves me time.

0. You *only* need to change your shared libc when you want to make use of
   DNS and when you are *not* running NIS.

1. The ready-made shared libcs for SunOS4.1 (*not* 4.1.1, sorry) are
   available via ftp: user=anonymous  passwd=<your_email_address>
   at host dutrde1.tudelft.nl (130.161.180.13)
   in the dir /pub/library
   If you want the libcs for SunOS4.1.1 and you don't want to build them
   yourself, try finding out where they are by making use of the "archie"
   facility: rlogin quiche.cs.mcgill.ca -l archie

2. I include a few articles which describe how to build the shared
   libc.so.* yourself.

3. I add a few other articles which describe how to adjust libc.sa.*
   and how to make some extra modifications to customize the shared libcs.

Good luck.
Regards, John-Paul

Ah, something I just enabled on my Sun.  Here's a previous posting
that may be helpful.  "It worked for me."

Newsgroups: osu.sys.sun.managers
Subject: Revised posting on how to create libc_resolv.so under SunOS 4.1
Date: 19 May 90 03:59:57 GMT
Distribution: osu
Organization: Sun-Managers

Evan Wetstone's posting to Sun-Spots about libc+resolv under 4.1 has reminded
me to repost a slightly revised version of the instructions.  This is prompted
by 3 things:
(1) The original, virgin /usr/lib/shlib.etc/README file has an oversight in it;
    The original mentions that 2 files in the archive library need to be
    renamed after they are extracted, because the names are truncated at 16
    characters.  This is true for the Sun-3 and Sun-3x, but on Sun-4's and
    Sun-4c's (SPARCstation-1's, 1+'s, and presumably SLC's), there is an
    additional library module whose name is also truncated.  This is corrected.

(2) Several people complained to me that my instructions, being placed as an
    addendum rather than in line with the rest of the instructions, were thus
    unneccessarily confusing, and could even (if misinterpreted) cause someone
    to build a libc that would not work.

(3) I accidentally included my .signature file at the end of the posting,
    and then told everyone to append the rest of my message to their README
    files, thus immortalizing my .signature in everybody's README (^:  I
    humbly apologize ...

So, without further ado, here is the revised version of the file
/usr/lib/shlib.etc/README.  I recommend backing up the original, nuke my
previous version (the one that Evan re-posted), and insert this in its place.

	  Sun Microsystems, Inc.	|  This is Stouffer's.  It uses red.

	  sun!poseur!earle		| Pretty damn convincing argument, eh?

This is a procedure you can use to substitute or add 
a module in your shared libc C library. 

Note! If you are interested in a System V libc, please substitute
	libc_pic.a for libcs5_pic.a in step 3, 
	libc.so.x.y.z for libcs5.so.x.y.z in step 8.
