Hi everyone,

I am not very familiar with the UNIX market and would like to ask
a couple of questions.

1) are there any companies which teach UNIX topics such as system
   management, networking, etc? addresses? prices?

2) what are the most popular magazines in the UNIX area?

    Thanks a lot. Please reply directly to:   [e-mail]

It should have read as follows (I apologize for the error):

3. Is there a way to prepend or append characters to BUFFERS without
   (a) introducing newlines between additions (yanking to an uppercase
   buffer appends to text already in the buffer, but on a new line) &/or
   (b) writing to the file and deleting to the named buffer (in other
   words, are there ways to put characters in named buffers other than
   yanking/deleting text)?

If you're concerned about advanced Unix security, Posix-conforming
systems, or moving from Unix programming to Unix system
administration, plan to be at the Sun User Group Conference (San Jose
Convention Center) on Monday, December 7, 1992 for one of the full day
tutorials.  The Conference and Exhibition extends through Thursday.

All-day tutorials will focus on these topics and others of interest to
novice and experienced Unix users as well as Unix programmers who want
to expand their theoretical and practical knowledge.

Special offer: 5 full conference registrations (each includes a day of
tutorial) for the price of 4 when preregistering with a single payment.

Full-day tutorials currently scheduled include:
- Advanced Unix Security (Matt Bishop, Dartmouth College)
- Preparing for Disaster (a.m. - Brent Chapman, Great Circle Associates),
  plus, Why have Computer Security? (p.m. Bob Baldwin, Tandem Computers)
- Sun Network Debugging (Smoot Carl-Mitchell, Texas Internet Consulting)
- Topics in Perl (Tom Christiansen, Convex Computer Corporation)
- Programming in POSIX (Jeffrey S. Haemer, Canary Software)
- UNIX Programming Tools (Kenneth Ingham, consultant)
- The Internet and its Protocols (William LeFebvre, Northwestern University)
- Introduction to UNIX System Administration (Dinah McNutt, Tivoli Systems)
- Integrating C Code and Xt Widgets (Craig Rudlin, MD, Medical Software and Computer Systems)

If you just want to go to the exhibits, ask for a free show-only pass.

Hello,

I'm looking for a tcsh like input routine which would be callable from a C or
FORTRAN program. I just want to be able to read a line of text from the user
with tcsh-like (or emacs-like!) command line editing/recall features.

I'm working on a SPARC with SUNOS 4.1.3 but obviously the more general and
portable the solution the better!

As a bonus there would also be another routine which could modify the recall
list, but this is not essential as I could probably hack this myself given
the first subroutine.

Thanks for any help,

Karl Glazebrook.

I think GNU Ghostscript has an ASCII output option that will generate
text positioned approximately where it is supposed to be on a page
with anything else omitted.

It's non-trivial in the general case because you have to be able to handle
the entire postscript language to interpret the positioning and scaling
effects.  Plus you'll miss things where fonts have been converted to
curves and manipulated for artistic but still readable effects.  A
quick and dirty approach is to just extract the strings in parens
from the postscript and try to assemble them into text.  A more ambitious
project would be to modify the Ghostscript ascii output to maintain
some font size and type info that could be used by the speech synthesizer
to vary the output effects.

The leading program for time series analysis is probably RATS, which runs
under DOS, the Macintosh, Unix and perhaps some other operating systems
as well.

The company that writes this is located in Evanston, IL.  Their name used
to be VAR econometrics, but they might well have changed it about a year ago
(perhaps to "Estima", but I could have them confused with another company).

RATS stands for something like "regression analysis for time series" and
contains a broad array of time series analysis functions including specral
analysis.

If you cant track this down yourself, contact me by email and I will send
you the phone number.

You don't say in this post whether you're running Xenix or UNIX
and there are different tools to determine problems with streams
in each.  Xenix comes with a program 'sw', UNIX comes with crash, and
there are some freely distributed monitor programs such as u386mon
available from various ftp sites.

Xenix sw displays:

Subject: Unlocking named pipes
Keywords: named pipe
Date: 17 Nov 92 06:11:16 GMT
Followup-To: [e-mail]
To:       [e-mail]

I'm having a bit of trouble figuring out what's wrong with the
following usage of named pipes. I have 12 large compressed files which
I would like to merge/sort (they are sorted) without having to
decompress all of them before merging. So, I've written a simple script
to create 12 named pipes with mknod, say pipe1..pipe12. I begin
background processes to zcat each of the 12 files to one of the pipes
in sequence. I then start 'sort <switches> -m pipe1 .. pipe12 | <stuff> >
outputfile'.

Things go fine for a while, then the entire process freezes. The
output stream stops, and all processes go into IW wait, as if waiting
for something to happen. While in deadlock, if I try to read any of
the pipes, they each have data waiting, so all seems to be fine. So
who stopped everything and why?

Sort is able to merge at most 16 files at once, so I don't think
there's anything wrong there. Is there another anomoly in sort that
might cause this failure?

As best I can tell, sort found a depleted pipe that zcat couldn't keep
up with (perhaps sort is reading large buffers?), but no EOF, and
started sleeping. However, this isn't logical since the sort process
is followed by 3 other heavyweight processes in the pipe before the
output is written, so I would think that zcat could feed the pipes
fast enough. Besides, I thought processes would handle FIFO's normally
and sleep for at most a few seconds if it found and empty one before
hitting EOF.

By the way, in case it proves significant: I'm using SunOS 4.1.2 on a
SPARC. Standard sort, zcat, etc. Named pipes are created with mknod
-p. I've also tried sleeping for a few seconds before starting things,
with no results.

Can someone clear up the confusion, or at least add postulations to
the heap?

Please e-mail to [e-mail] or post here.

Better go all the way and get emacs, with tree-dired.  You not only get all
funtions most file managers execute, but you can add some of your own.  And
then, this would be just the beginning of using emacs for almost everything,
instead of hundreds of little frozen utilities.

Subject: lib77 "flush" call. Where is it in UNIX?
Date: 17 Nov 92 12:23:03 GMT
To:       [e-mail]

Dear fellow UNIX and HP-UX folks,

   I am trying to bring up the graphics package MONGO on our HP-720 machine
   and I have encountered a problem.  It seems that MONGO uses a "flush"
   call deep in its IO guts.  Looking through all the HP-UX libraries I
   find no such routine.  Rather, I find "pflushli", "flushinp", "intrflush",
   "__cflush", "fflush", and "fflush_p."  Some of these are clearly not
   what I want, but others are less certainly wrong.  I find no documentation
   for any of these readily available.  How do I proceed?  Has anybody out
   there installed MONGO under HP-UX?

Cheers,

Lowell Tacconi-Garman

This is a UNIX question, not a C question.  Consequently, I'm
cross-posting to comp.unix.questions and directing followups there.

There are multiple ways.  You can have the child send some signal to
the parent.  You can create a pipe (or other stream connection) and
have the child write and the parent read.  You can use semaphores, if
your system provides them.  There are probably other ways that don't
come to mind at the moment.

Which one is best?  That depends on many factors, such as the required
response time, how much information needs to be passed (besides the
bare fact of the wakeup), how widely portable the code needs to be,
what if anything the parent is doing while waiting....

This is a UNIX question, not a C question, and I'm therefore
crossposting to comp.unix.questions and redirecting followups there.

In general, you can't.  The file descriptor may not be connected to a
file (it may be a pipe or (other) socket or TLI stream or a device or
maybe something else).  Even if it is a file, the file may have no
names any longer, or it may have multiple names.  Even if it has at
least one name, there may be no name by which it is accessible to your
process or possibly even other processes.  And even if you assume it
has a name that you could use to refer to it by, there is no way to
find any such name short of a full scan of all filesystems, which can
take a *long* time.

You're usually best off writing wrappers for open/close (or
fopen/fclose if you're using stdio) that remember filenames.  The major
case where this doesn't work is when you're dealing with redirection to
or from files, in which case you're pretty much out of luck.

This means simply that talkd on the remote machine did a
gethostbyaddr() on your machine's address and got a failure indication.

Either the remote machine is broken somehow or whatever nameserver is
responsible for the relevant .in-addr.arpa zone is misbehaving, or
(worst case) hasn't been set up.

> If so, how can this situation be circumvented?

The right way to fix it is to fix whatever's wrong.  A workable
substitute is to fix talkd so that if gethostbyaddr() fails, it prints
the numeric address instead (and in parallel, fix talk to accept
numeric addresses).  This is what I've done, and sometimes when the net
is flaking out (and thereby breaking the DNS) it's proven useful.

Thanks to all who responded.  I was surprised at the number of different
responses I received, (most involving setuid()) which led me to realize my
wording must've been real vague.

What I was looking for was something along the lines of how to change the
effective user id of a process who's source I may not be able to modify, by
some other means, e.g. from another process.  Many suggested writing a device
driver or system call to do this.  Here is one answer along those lines.
---

This is one of those dirty tricks I've always wanted to get around to
figuring out a way to do... (without kernel source, that is)

I believe it could be done by writing a device driver. Open the device
driver and write commands to it, and it does the dirty work. For
instance, send it 8 bytes containing the process to change and the uid
to change it to.

The uid, in every version of Unix I've seen, is stored in the proc
structure in the kernel. You should be able to fiddle with this at
will in a device driver, and since it's in the proc structure and not
the u area, it'll always be there even if the process is swapped out.
It *should* be just a matter of searching for the entry and changing
it.

This technique should also serve to implement something like renice()
under Xenix, which doesn't have it. (The nice value also being stored
in the proc structure.)

The original marketing niche for MS-DOS was as a stepping stone from the
8-bit CP/M world to the multiuser 16-bit world of Xenix.  Microsoft, in
the early 80's, fully intended to make Xenix their high-end OS.  However,
the market chose otherwise.

You can write a "flush" that calls "fflush" (which is a standard C
routine, and you should have a man page for it). You will need to use the
HP-UX 'fstream' routine to map the FORTRAN unit number to a C stream number.

I can't send you source for flush since it is licensed, but you can
have these routines I used to make it work:

      function igetfstream (lunit)
c
c     Purpose:
c        Return the FILE pointer corresponding to unit 'lunit',
c        or 0 if unit 'lunit' is not open.
c
      logical opened
c
c
c     write (6,*) 'igetfstream called for unit ', lunit
      inquire (unit=lunit, opened=opened)
      if (opened) then
         igetfstream = fstream (lunit)
         if (igetfstream .eq. 0) then
            if (lunit .eq. 5) then
               igetfstream = igetstdin ()
            else if (lunit .eq. 6) then
               igetfstream = igetstdout ()
            else if (lunit .eq. 7) then
               igetfstream = igetstderr ()
            end if
         end if
      else
         igetfstream = 0
      end if
c     write (6,'(1x,a,z9.8)') 'igetfstream returning ', igetfstream
      return
      end

To get the stream number for stdin/stdout/stderr, try:

/*
 * Return the FILE pointer to stdin.
 */

#include <stdio.h>

    FILE *
igetstdin_ ()
{
    return (stdin);
}


/*
 * Return the FILE pointer to stdout.
 */

#include <stdio.h>

    FILE *
igetstdout_ ()
{
    return (stdout);
}


/*
 * Return the FILE pointer to stderr.
 */

#include <stdio.h>

    FILE *
igetstderr_ ()
{
    return (stderr);
}


Note that always use "+ppu" for f77 compilations; you will need
to remove the trailing '_' on the C routines if you don't.

I have (cross-)posted this to comp.sys.hp.

Hi:

This is a (shortened) repost of an article for which I got no responses. Writing
to a memory region allocated with mmap call using MAP_FILE and
MAP_SHARED causes a segmentation fault (RS6000 under AIX 3.2) when
it is done over NFS. Mapping to the same file locally works fine.
Documentation, as far as I can tell, does not mention
NFS as a limitation. Is mmap supposed to work over NFS and this is an AIX
bug, or is it not supposed to work and it is a documentation problem ?

There is no need to write another device driver for this.  /dev/kmem will
suffice.

Hello, net!

I need to build some docs, and some of the stuff needs pic. I know
it isn't public domain (or am I wrong?), so what I would like was
to find something that does the work, but available in the public domain.

Is there any such thing.

Thanks in advance for any info.

BTW, are theese the right groups to ask this kind of questions. Please

The agrep package (approximate pattern matching) has many of the grep functions

You can do it by poking about in /dev/kmem, but it's not safe.  Consider:

Process A                     Process B               Process C
Open /dev/kmem                <runs>
Find B proc table entry       <runs>
Update proc table entry       <exits>                 <starts up>

Between the time when Process A locates the proc table entry for Process B
and the time that it updates the entry, Process B exits and Process C is
started -- and given Process B's old table entry.  You end up updating
the wrong process.

Am I to understand that unix file management is in the "kernel" and can
not be intercepted before and after kernel operations?  Even DOS seperates
the file system and kernel enough that you can use stacker or something
between the files system and the kernel.

Subject: rexec does not search for ~/.netrc file
Keywords: rexec, netrc
Date: 17 Nov 92 22:29:42 GMT
NNTP-Posting-Host: boogie.cs.utexas.edu
To:       [e-mail]

I am trying to use rexec(3N) on a Sun SparcStation to start a server
on a remote host (also a Sun SparcStation). The synopsis of the call
(as given in the man page) is:

SYNOPSIS
     rem = rexec(ahost, inport, user, passwd, cmd, fd2p);
     char **ahost;
     u_short inport;
     char *user, *passwd, *cmd;
     int *fd2p;

Here's the relevant portion of the description from the man page:

DESCRIPTION
    ...
     If  a  username  and password are both specified, then these
     are used to authenticate to the foreign host; otherwise  the
     environment  and  then  the  user's  .netrc file in his home
     directory are searched for appropriate information.  If  all
     this fails, the user is prompted for the information.
    ...

Now, I have a .netrc file in my home directory which has lines of the
following form, one line for each foreign host:

machine machinename login mylogin password mypassword

Here's how I call rexec in my program (I have also shown some other
relevant variables used in the call):

int port;    /* set using getservent ("exec", "tcp") call */
char *rhost;    /* set to the foreign host name */
char *srvr;    /* set to full path name of my server */

s = rexec (&rhost, port, (char *) NULL, (char *) NULL,
       srvr, (char *) NULL);

Even though I have the .netrc file set up in my home directory, the
call still prompts me for the username and password.

My question is: Am I doing something wrong here, or is this a commonly
known bug? Any pointers will be appreciated.

My machine is a SparcStation ELC running SunOS 4.1.2. All the remote
hosts (where I am trying to start up my server) are SparcStation 1's
also running SunOS 4.1.2.

Thanks in advance,

No, no, no, no, no....OS/2, Windows, DOS etc. have PROVED that you don't
have to be a system administrator to install an OS.  Why do you insist on
this dogma "if you aren't computer literate enough to install Unix, you
should pay someone to do it."  Why not make unix easy enough to install
that you don't have to do either?  Why force the problem onto the user
instead of just FIXING it?  Why defend a flaw?

I won't defend Dos, or windows' or OS/2s' flaws.  I will highlight their
strong points.  Highlight unixes' strong points, but FIX IT'S FLAWS.

Overly complex installation is a flaw.

All of these are considerably easier to use then a text editor.  Many cars
will (rightly) make a sound if you leave your keys in.  They will also
(rightly) make a sound if you leave your lights on when the engine is
off.  It would be (and perhaps is, in some cars) nice if you could turn
these off.  But for my, girlfriend, who is very intelligent, but occasionally
forgets her lights and keys, the buzzers are a Godsend.  And for me,
who can forget and type qw instead of wq, a prompt "haven't saved yet"
would be nice.  BTW, this is not asking for superflurous time wasting
prompting.  VI will NOT LET YOU QUIT with a Q.  It must be wq or Q!.  So
if I type Q, why not ask me if I meant WQ?  Easier for the user, easeir
for the power user that forgets.

Or compile it?  write can write ascii as well as VI!

process interruption is different from exit.  Exit implies "update setup
files etc., and perhaps prompt me if I want to save"  Process interruption
implies "quit unconditionally."

That's fine...your keyboard doesn't have an F1 key and you don't want help.
My keyboard DOES have an F1 key, and unix doesn't have a standard F1 key.
If I want to bind F1 on my computer, having help on it doesn't matter.  Think
about it...it would be intercepted before it gets sent, and translated,
wouldn't it?  And for those of us that don't know how to bind keys yet,
it would go through to help.

Yes...I keep saying right because I'm thinking about what hand I use to
type it.

Non standard QWERTY-incompliant keyboards are certainly not my problem.
99.9% of qwerty keyboards (and every one I have seen) has a semicolon beside
the l.  The other .1% are so nonstandard that perhaps their hjkl aren't
in a row either.

Thus the beauty of the (till now) unused F1 key.  Besides, one would
assume that VI would be configurable enough that you could change the
key mappings of the keys!  Or at least turn off help if you wanted to.

Well, in the PC world (blaspheme!!!!) you tell programs what editor you
want to use and what command line options to send to them.  And guess what
if you want to change that information, you don't have to edit some
invisible file that the computer has (annoyingly) placed in your work
directory.  The program updates it's OWN config file.  (although you could
do it manually if you're into that kind of thing)

I see.  For other people it is a benefit?  Can you explain how it is to
their benefit to have help do nothing?

yes programs DO decay.  See that crap above this line?  That's what
happens when I try to use my arrow keys.  Let's see what happens when
I try to use my f1 key?  Beep.  Where is built in help?  It's not there.

VI is decaying.  It is not keeping up with the hardware.  It is not keeping
up with competing software.  Anyone in their right mind given a choice
would not use vi unless they are already familiar with it (or the only
choice is emacs).

Let's not let this decay happen to unix.

Relinking the kernal and installing the new unix automatically creates
/unix.old.  This is fine unless you screw up the kernel twice in a row
and have nothing to boot.  This is where the /unix.good can save the day.
I always create a /unix.good from a known, working, kernel.  It, however,
does not have to always be the latest one, just one that will boot.

Single user mode is important because 'ps' may not run with the new
kernel (without '-n /unix.old'), which may, in turn, cause shutdown to
hang or not shut everything down.  Many applications (ingres...) use
ps to find their daemons and servers and so may not terminate properly.
