Subject: 6.06: Some acronyms
APAR - Authorized Program Analysis Report
Created internaly by a systems programmer to solve a code bug.
BOS - Base Operating System
DCR - design change request
Someone asked to change something.
LPP - Licensed Program Product
ODM - Object Data Manager
Don't touch until you grok it.
PRPQ - programming request for price quotation
Essentialy, a program that is not available off-the-shelf.
(e.g. HACMP started as a PRPQ, you could not order HACMP, but
you could ask IBM for a highly-available solution)
PTF - Program Temporary Fix
Temporary ? Yes! Read "The Tao of Computing".
SMIT - System Management Interface Tool
SMITTY - SMIT, tty interface, no bells, no whistles. "alias smit=smitty"
Y2K - Done. Total non-event.

Subject: 6.07: How do I get this by mailserver or ftp?
Since the articles are crossposted to news.answers, any archive
carrying that newsgroup will also have these articles. In particular,
try ftp'ing to rtfm.mit.edu and checking the directory
pub/usenet/news.answers. This FAQ is archived as "aix-faq/part[12345]".
The FAQ is also availible via email using the address
mail-server@rtfm.MIT.edu two examples of how you might use this from a
UNIX prompt follow:
echo help | mail mail-server@rtfm.MIT.edu
echo send usenet/news.answers/aix-faq/part1 | mail mail-server@rtfm.MIT.edu

Subject: 6.10: Comp.unix.aix archive availible on the WWW
Michael Staats & Fred Hucht have informed me that a searchable archive of
comp.unix.aix is availible at:
<http://www.thp.Uni-Duisburg.DE/cuaix/cuaix.html>.
------------------------------
Subject: 6.11: How can I access the comp.unix.aix newsgroup
via email (or Web)?
From: Ciaran Deignan <C.Deignan@frec.bull.fr>
It is possible to get "digests" of the AIX newsgroup by email. Each
digest contains a summary (just the subject lines from each post)
plus the contents of a series of news articles posted to the newsgroup.
Each digest is about 800 lines long, and the newsgroup typically generates
5 digest mails per day.
To get these digests, you have to subscribe to a mailing list. Send
an email to the address majordomo@dmshome.youngstown.oh.us, and put
the text "subscribe aix-digest" in the body of the message.
[Editor's note: The above address does not appear to work any longer, if
anyone knows of a functional equivalent please drop me a note.]
It is equally possible to post articles to the newsgroup via email.
Any mail sent to the address aixnews@cc.ysu.edu will be forwarded to
the comp.unix.aix newsgroup.
These services are provided by Doug Sewell <doug@cc.ysu.edu>.
Comp.unix.aix can be accessed from the web via http://www.deja.com/

Subject: 8.03: How do I set up postscript accounting?
[ formerly in section 1.118 ]
/* pswrap.c
compile with: cc pswrap.c -o pswrap -lqb
(for doc on the qb library see "understanding backend routines in libqb")
BTW: The log_charge() function doesn't seem to do anything,
but log_pages() updates the accounting info.
Ephraim Vider, original author
--
Feb 10, 1993
You can set pswrap up to use either the accounting file specified in
/etc/qconfig (which means that you need to get your data from 'pac') or
you can comment out the #define WANT_PAC line and then the accounting
data will only go into the ACCTFILE.
Also modified the logging to the ASCII acctfile so that it looks more
readable.

# rmksysb #
#######################################################################
# #
# Description: #
# creates a bootable mksysb backup of a remote system running #
# AIX 3.x or lists the Table of Contents of the current tape #
# #
# Usage: #
# ./rmksysb $1 [$2] #
# $1 - remote host to be backed up #
# $2 - optional: local tape device (default: rmt0) #
# or: #
# ./rmksysb -l [$2] #
# to list Table of Contents saveset on tape in $2 #
# (only useful on tapes created by rmksysb) #
# #
# Output: #
# a bootable mksysb of the remote system #
# or a listing of the TOC saveset on the current tape #
# #
# Remarks: #
# . rmksysb can only be used by root #
# . this script will use tapedevice .1, so if #
# a >2.3GB drive is used: check density_set_1 #
# . the remote host needs /.rhosts to include the local host #
# for root access (+ shell enabled in /etc/inetd.conf) #
# . you will need some room (>1.5MB) on /tmp on the remote host #
# for standard mksysb .archive.list.* etc. #
# . remote standard output & standard error (except dd/chdev) #
# will go to local stdout & stderr #
# . redirecting stdout can create quite large log-files (2MB) #
# . AIX versions should not be too far apart as the boot-saveset#
# comes from the local system & the rest from the remote #
# (tested on AIX 3.2.5, AIX 4+ definitely won't work!!!) #
# . most likely this script will fail with multi-tape mksysb's: #
# another incentive to keep rootvg as small as possible! #

Subject: 8.08: Disabling software flow control; using RTS/CTS.
[ formerly in section 1.613 ]
/* This program is an adaptation of a program provided by IBM Defect Support.
It is provided without warrantee, or support.
The syntax of the command is:
setrts tty [tty [tty [...]]]
The program will loop through each tty provided on the command line, and
turn on the 'rts' line discipline. The program does not require that
the Carrier Detect signal be held high to keep the serial device from
blocking on the attempt to open it. The program works for all valid ttys.
BUGS: None that are known; however, using the program to set 'ptys' may
cause the 'pty' to become unusable.
This program was written by Robin D. Wilson, Pencom Software (with the
specific 'ioctl()' call provided by the IBM Defect Support Center.
I call it: "setrts"
To compile:
cc -O -o setrts setrts.c
strip setrts
(Funny, but if you strip with the compiler (i.e., cc -s), you end up with
120 extra bytes in the executable...)

Subject: 8.09: How can I hack libc.a to alter how hostnames are resolved?
[ formerly in section 1.618 ]
[ Editor's note: You might want to see Question 2.07 for advice on
recovering from a deleted or corrupted libc.a before attempting this
hack. Note that this procedure is for AIX 3.2 ONLY --- AIX 4.x already
has a supported method of controling name resolution. See question 1.800.]
1. get the resolv+ source (I see a copy on ftp.uu.net in networking/ip/dns
and there are likely copies elsewhere). We are using version 2.1.1,
which appears to be the latest available. gethostnamadr.c needs a couple
of additions:
23a24,26
> #ifdef _AIX
> #include <sys/time.h>
> #endif
35a39,41
> #ifdef _AIX
> #include <sys/ioctl.h> /* for SIOCGIFCONF */
> #else
36a43
> #endif
2. Use the following instead of the supplied shlib/Makefile:
LIBP= gethostnamadr.o herror.o res_data.o res_query.o res_mkquery.o \
sethostent.o res_send.o res_debug.o res_comp.o res_init.o
CFLAGS= -O -D_BSD=43 -D_NO_PROTO -DNIS -DDEBUG -U__STR__
all: shr.o
shr.o: $(LIBP) setup
ld -o $@ /lib/syscalls.exp $(LIBP) tmp.o -bM:SRE -bE:shr.exp -bE:/lib/syscalls.exp -bI:crypt.imp -H512 -T512 -bh:4 -lc
setup:
rm -f libc.a crypt.imp
cp /lib/libc.a .
chmod 755 libc.a
ar xv libc.a shr.o
/bin/dump -nv shr.o | grep EXP | awk '{print $$NF}' > shr.exp
ld -o tmp.o -bnso shr.o -r
@ echo '#!' > crypt.imp
@ echo __crypt >> crypt.imp
@ echo __setkey >> crypt.imp
@ echo __encrypt >> crypt.imp
clean:
rm -f shr.o tmp.o crypt.imp shr.exp $(LIBP) libc.a
install_libc: install_libc.c
cc -o $@ install_libc.c -bnso -bI:/lib/syscalls.exp
herror.o: ../herror.c
$(CC) $(CFLAGS) -c ../herror.c
res_comp.o: ../res_comp.c
$(CC) $(CFLAGS) -c ../res_comp.c
res_debug.o: ../res_debug.c
$(CC) $(CFLAGS) -c ../res_debug.c
res_data.o: ../res_data.c
$(CC) $(CFLAGS) -c ../res_data.c
res_init.o: ../res_init.c
$(CC) $(CFLAGS) -c ../res_init.c
res_mkquery.o: ../res_mkquery.c
$(CC) $(CFLAGS) -c ../res_mkquery.c
res_query.o: ../res_query.c
$(CC) $(CFLAGS) -c ../res_query.c
res_send.o: ../res_send.c
$(CC) $(CFLAGS) -c ../res_send.c
gethostnamadr.o: ../gethostnamadr.c
$(CC) $(CFLAGS) -c ../gethostnamadr.c
sethostent.o: ../sethostent.c
$(CC) $(CFLAGS) -c ../sethostent.c
strpbrk.o: ../strpbrk.c
$(CC) $(CFLAGS) -c ../strpbrk.c
strerror.o: ../strerror.c
$(CC) $(CFLAGS) -c ../strerror.c
3. As shipped, IBM's /lib/syscalls.exp contains an entry for fork(). This
needs to be removed as it will cause the new shr.o to use the system call
entry point rather than the library wrapper and this can cause some rather
odd behavior. For example, I ran across one using the '!' command in vi
where the error/informational messages were corrupted.
4. You can use "ar r libc.a shr.o" but that will leave a big hole in libc.a,
since the new shr.o is slightly bigger than the original. I always extract
all the .o's from libc.a and build a brand new one - suit yourself.
5. Before the next step, you'll want to set up the two configuration files.
The first is /etc/resolv.conf and it is basically the same as before
except for the new keyword "search" - intended to replace the "domain". See
the resolver.5 manual page for details (included with the resolv+ source).
The other file is /etc/host.conf, which is where you set the order of
search. See resolv+.8 for information on this.
6. Now, the only tricky part left is to get the new libc.a installed. You'll
note the Makefile has a target for install_libc. Just put the following
in install_lib.c and run "make install_libc" to build.
------------------------------- begin install_libc.c -------------------------
#include <stdio.h>
static char *nodns[] = { "/usr/ccs/lib/libc.a" , "/usr/ccs/lib/libc.a.ORIG" };
static char *hasdns[] = { "/usr/ccs/lib/libc.a.NEW" , "/usr/ccs/lib/libc.a" };
#define OLD (0)
#define NEW (1)
main()
{
if(link(nodns[OLD],nodns[NEW])) {
perror("link");
exit(1);
}
if(unlink(nodns[OLD])) {
perror("unlink");
exit(1);
}
if(link(hasdns[OLD],hasdns[NEW])) {
perror("link");
exit(1);
}
if(unlink(hasdns[OLD])) {
perror("unlink");
exit(1);
}
exit(0);
}
------------------------------- end install_libc.c ---------------------------
7. You'll want to do this on a quiet machine. Move the new libc.a to
/usr/ccs/lib/libc.a.NEW, then run install_libc. It is probably a good
idea to reboot afterwords (though not strictly required). We have a similar
program called restore_libc (exercise for the reader) for backing out the
change.
Rather than do this on every machine (we have 170+ RS/6000's), I simply
put this new libc.a into my network-installable image, which I blasted
out over the year-end holiday break (I created a method for loading a new
image onto machines without having to boot off of floppies and turn keys).
Of course, for the really cautious, you can always make the change after
booting off of the maintenance floppies...

Subject: 8.10: How do I make an export list from a library archive?
[ formerly in section 2.17 ]
This script will only extract the "export"able names and should be
useful in starting the shared library creation process. The user must
determine which names should be included in the import and export lists.
It's only been tested on a few library archives.
#!/bin/ksh
#
# mkexps - make export list
# This program creates an export list by combining all the "." and normal names
# into one list.
#
if [[ "$#" -ne 1 ]]
then
print "Usage: mkexps ArchiveFile"
exit -2
fi
if [[ ! -f $1 ]]
then
print "mkexps: Cannot open file \"$1\""
exit -1
fi
dump -g $1 | awk '
BEGIN {
top = 1
}
/^[ ]*[0-9][0-9]*/ {
if ( (n = index( $2, "." )) > 0 ) {
export_array[ top++ ] = substr( $2, n+1, length( $2 ))
}
else {
export_array[ top++ ] = $2
}
}
END {
for ( i = 1; i < top; i++ )
{
print export_array[ i ]
}
}' | sort | uniq
