  echo This script only works on AIX 3.2.

You can't change the protocol stack on a tty unless something is connected
and active. Log into the RS/6000 via the modem, then run:

	stty add rts

directly on the tty. That should add RTS/CTS to the protocol stack for you.


Also, AIX tunes (by default) the serial ports for interactive input, which
means the processor only gets an interrupt every 14 characters (if
memory serves from an IBM class on tuning), or on a timeout. The
latest version of the tuning guide has a script (allegedly, my copy is
still on order) that can be used to change this. Dunno if this really
will help, but the guys from the IBM class suggest it for file
transfers.

Hello AIXLand,

	Does anyone have a RS/6000 Model 320 or 320H that they would like to
sell or trade for a new Sun SparcStation or SCSI devices (Disk, 8mm/4mm tape
etc...)?

	I am looking for a gently used 320 or 320H with the following:

	8MB, 16MB or No Memory (I have some if you want to keep it)
	SCSI controller
	Ethernet Controller
	Keyboard/Mouse
	Monochrome or Color Monitor
	Internal SCSI boot disk or *diskless*
	(If diskless must include AIX 3.2.X distribution on 1/4, 8mm or CD)
	AIX OS Distribution on 1/4",8mm or CD-ROM (No License needed will buy
      	locally)
	Manuals and Documentation (either Paper or CD-ROM if you want to part
				   with them)

	If you cant tell I'm flexible and will listen to about any offer. I'm
looking to pick up a nice-condition used system to use for SCSI peripheral
(Disk,tape,optical) testing and compatibility verifacation. 

	Purchasing a system for cash is fine, but in case your interested I
have some hardware I could trade too. New SparcStation 1, 1+ or 2 systems
as well as *new* Seagate, Micropolis and DEC SCSI disk drives, Exabyte 8mm tape 
drives or Hewlett-Packard 4mm DAT tape drives (HP 4mm is IBM's new 4mm drive).

	So... If you are in the "Get rid of that 320/320H" frame of mind
please respond via Email to the below address and let's talk. Its no good
filling up this newsgroup with sale negotiations! :-)

Subject: Printer Accounting...
Date: 14 Dec 92 13:59:20 GMT
Organization: Visual Edge Software Ltd.

Hi all,  having a few problems with setting up the printer accounting.

1. Essentially, I have specified my acctfile in /etc/qconfig, made sure
the file was "digested", made sure my acctfile existed and was writable,
made sure accounting was on, and STILL have had none of my printed
files showing up in the log.  All my users print via "lp"...none use
enq...is this the problem?

2. Another oddity I have noticed is that I consistently get headers printed
for remote jobs to my printer, but local ones don't have them.  I have
made sure that I have a header = never line in the qconfig file, but
short of physically moving the "burst" header page from /usr/lib/lpd/pio/
burst I have not been able to turn it off....

Any hints/ideas?  I am running AIX 3.2 on an RS6000, and my accounting
system is 3.2 with PTF U404902/U405566 committed.

All help is appreciated...

Use the command 'lsvirprt'.  Don't use any parameters and it will
run in an interactive mode that will give you a menu of all virtual

Alternately you could just add -DHAS_UTMP_UT_HOST to MAIN_DEFINES in the

The only good way is to use the scsi pass-through ioctl() calls, and you
have to be root and open the device in diagnostics mode(!!).
The code looks like this:

do_status(char *pcTape)
{
        int i;
        int nTapeDiag;
        static char buf[SIZE];
        static struct sc_iocmd  scInquiry = {
                0x38, buf, 5, 0, 0, 0, 0, 0, 0, 0, B_READ, 0, 0, 0,
                6, { 0x12, 0, 0, 0, 0x38, 0  }
        };
        static struct sc_iocmd  scMode = {
                80, buf, 5, 0, 0, 0, 0, 0, 0, 0, B_READ, 0, 0, 0,
                6, { 0x1a, 0, 0, 0, 80, }
        };


        if (debug)
                fprintf(stderr,"do_status\n");

        if (0 > (nTapeDiag = openx(pcTape,O_RDONLY,0,SC_DIAGNOSTIC))) {
                perror("openx\n");
                return 1;
        }
        printf("Drive %s", pcTape);
        if (0 > ioctl(nTapeDiag,STIOCMD,&scMode) &&
                 0 > ioctl(nTapeDiag,STIOCMD,&scMode)) {
                perror("ioctl IOCMD {1a, 0, 0, 0, 0xff, 0}");
                return 1;
        }
        if (buf[1] == 0) {
                printf(" is off line");
        } else {
                printf(" is on line");

                if (buf[2]&0x80)
                        printf(", write-protected");
                else
                        printf(", read/write");
                printf("\n");
        }
        close(nTapeDiag);
        printf("\n");
        return 0;
}

There's lots of other good status bits in there you can check; look in
the EXABYTE manual for details on the hex 1A Mode Sense command.

We have similar memory requirements.  We work around the data memory
limits by using shared memory.  Assuming you are writing C programs,
you can use the shmget() system call to get more than 256MB of dynamic
memory.

compiling, and debugging.  I don't know jack about RS/6000's or AIX,
so I would appreciate any thoughts people have on the following
questions.

* Do you like AIX for development and administration?  Compared to
SunOS or HP/UX does it have any glaring strengths or weaknesses.

* Are Emacs, GCC, and GDB available for RS/6000?

* Is Centerline-C available?

* Is the 350 a good database server?

* Is AIX a Sys5 or a BSD environment?

* Is it generally easy or difficult to get publicly available software
(i.e. tcsh, new X clients, etc) to build?

* Is AIX stable?  (I hope this is a stupid question, but given Solaris

Article-I.D.: ecnet.9212111949.AA12276
Reply-To: jhidalgo@ecnet.ec (Javier Hidalgo E.)


I4m still working on solving my CNAME problem, which I asked about in a 
previous message to this newsgroup.  We4ve been able to isolate the
problem down to a few sendmail configuration questions.

We4ve defined a nameservice CNAME for c.ecnet.ec to ecnet.ec .
That seems to be working correctly; nslookup tests show the proper:

     c.ecnet.ec	canonical name = ECNET.ec

However, when we try to send mail from ecnet.ec to "c.ecnet.ec", mail fails 
with the following message:

Subject: Cc: jhidalgo... setsender: uid/gid = 211/206
jhidalgo@c.ecnet.ec... Connecting to ecnet.ec.tcp...
jhidalgo@c.ecnet.ec... Connecting to ecnet.ec (tcp)...
220 ecnet.ec Sendmail AIX 3.2/UCB 5.64/4.03 ready at Fri, 11 Dec 1992 14:17:44 -0500
>>> HELO ecnet.ec
553 There is a local configuration error.  The hostname is not recognized as local.
>>> QUIT
221 ecnet.ec: closing the connection.
jhidalgo@c.ecnet.ec... Service unavailable

The problem appears to be the fact that sendmail doesn4t do the CNAME
lookup before decided whether or not to send via ".local", and therefore
tries to send mail to back to the local machine using SMTP rather than 
".local" as it should.

Two questions: 1) is there a way to get sendmail to recognize that a
CNAME points to its own host machine? 2) What does "local" mean in the 
above error message?  It seems to us that the problem is, in fact, 
that ecnet.ec IS recognizing "ecnet.ec" as its own name....

Another point of interest:  mail for most other machines to this c.ecnet.ec
address does arrive successfully.  However, from a few machines, the 
message fails.  It does arrive in the sendmail queue, but for some reason
sendmail here tries to send the message to itself another time, with the
same results as above.  It would seem that to remote machine does a
CNAME lookup when establishing the SMTP connection, but doesn4t 
change the destination address in RCTP TO command.... 

Any ideas as to what4s going on?

You need to run xterm with the '+ut' flag or 'xterm*utmpInhibit: false'

Gee.  When I mentioned this problem a year or two ago I got nary a peep in
reply.  I concluded that I was the only one on the face of the earth who
really cares about my users' data.

As far as I know, the only place to get what you want is from Convex Computer
Corp. which has a "-V" option on their version of "restore".  This checks
the tape for readability and data consistancy.  For example, if you are
using "dump" on an active filesystem, "restore -V" will let you know whenever
there is an inconsistancy between the index and the actual data on the tape.
"restore -V" DOES NOT check the tape data against the disk data.  Thus,
the behavior of "restore -V" is the behaviour which you and I (and apparently
nobody else except other Convex customers) want.

When I suggested to Defect Support that it would be a good idea to
have this kind of option on AIX "restore" (and not difficult to
implement either), I was sent in search of a non-existant form.  I
gave up.

I would like to clarify a small detail.  If you use "backup by name"
("backup -i") instead of "backup by inode", then a "restore -T" WILL
actually verify the integrity of the data on the tape, since "backup
by name" does not generate an index the way "backup by inode" does.

However, this also means that you can't use "interactive restore" with
backups done "by name" - a major pain.
