Hi there,

I apologize if this's an FAQ :)

I'm porting a PD software to our hp9000/720 running HP-UX 8.07.  During
the ld stage of the make process, some of the symbols are unresolved,
which includes htonl and htons (about the byte ordering of host names).
I would like to know which library to use in the -l link flags.

Any response will be much appreciated.

Thanks in advance.

Regards,

Keywords: Wren9 Wren Seagate

We've just gotten hold of an HP-9000 (model 870 ??), and we're trying to
connect a Seagate Wren 9 1.9 GB disk.  I certainly can't configure it through
'sam', there is no entry for it in /etc/disktab, and there are no disks in
/etc/disktab that have specs close enough to allow an acceptable alias.

So, has anyone out there attached one of these, or any other non-HP disk ?
And how the hell do you do it.  I'm in the process of placing an entry in
/etc/disktab for the Wren, but I'm not sure what number the disk is recognised
as.  I presume it's something like  ST42100N or some similar model number-like
string.  Where is this string recognised from?  Does it come from the id-string
sent back from the disk ??  I was speaking to HP and they were implying that
if I couldn't get an accurate alias for the drive, then it WOULDN'T WORK.

Any help would be appreciated.

Thanks,

Stuart

How about the 4xxt->715t upgrade program ? 

The HP-IB interface on 4xxt series is no more available after
an upgrade to series 715! The HP-IB is suported only on 715s series
(through the EISA card) and there's no way to upgrade from a 4xxt to 715s!

We have lots of hp4xxt, used for HP-IB connected test&measurement 
peripherals. How can we take advantage of the new, great, blasting
(open list, you may add your own here...) machines and preserve
our investments (didn't you say so, HP?) ?

Is our case unique? 

Any proposal from HP?

No.  Lots of people need that fast HPIB interface.  I was told last week
about a new model, 745i, which has a non-EISA HPIB interface.  I don't
have any more information on it, yet.

Ok, who what where when and why.  The questions all reporters put in

My last and only DART CD, which had no instructions or clues on how
to use it, ended up corrupting my operating system.  I wrapped it in
lots of packing tape and put environmental hazard warning stickers
all over it and locked it in a Mosler safe... :-)

Periodic upgrades are a good idea.  But (and this is a BIG but! :-)
a once a year update should have start-from-the-beginning
instructions in it, since users can't be expected to remember how to
do an update after a year or two...

 This is WRONG.
 I boot my 700/RX from a Supermax without any problems.
 (You never heard of a Supermax computer ?
  It's a R3000/R4000 based multi cpu machine.)
 The only difficulty was is getting the software, as the local HP office

The XMaskEvent function only works with core events.  You cannot use it to get extension events.  You should be able to use XCheckTypedEvent instead.

You may also want to consider using the standard X input device extension, rather than the HP-proprietary input device extension.  The functionality is basically equivalent.

Try <shift-cntrl-reset> as a triple key sequence.
This should abruptly terminate the X server.
After that you can log out of the console.

We have noted a problem with utilizing 8mm tapes on HP 9000/720 and HP 9000/375
systems.  No matter how we set the minor device number, we cannot get the
device to rewind on close.  This does not seem to depend on the tape
manufacturer , although those we tried are all based on Exabyte 8200, I think. 
(We have RSquared and some other brand that HP recommended, even though HP
doesn't really support 8mm, it seems.)

We have had no such problem with our 4mm drives, so we feel we have a good grip
on how the SCSI tape driver interprets the bits in the minor number.

For now we have only left the special device file on the system who's name
implies no-rewind, but I am interested in knowing if there is a solution for
this.

This is what we have:
  /dev/rmt/0m    54  0x201402		4mm with rewind on close, SCSI id 4
  /dev/rmt/0mn   54  0x201403		4mm with no rewind on close, SCSI id 4
  /dev/rmt/1mn   54  0x201503		8mm with no rewind on close, SCSI id 5

trying /dev/rmt/1m 54 0x201502  does not give us rewind on close for the 8mm

Subject: Questions on "localy mounted file systems"
Date: 26 Jan 93 16:26:48 GMT
Organization: University of Utrecht, 3D Computer Vision Research Group
Originator: bartm@mind.cv.ruu.nl

Hello,

We've a 9000/710 work station which is used to run a specialized
image-processing application. For this application, both lots of swap space
and lots of space to store images is needed.

The 710 is served bij a 9000/750 with a 1.3Gb internal SCSI disk. Since this
disk is almost full (yes, believe it or not :-\) we're thinking of a solution
for the swapspace/diskspace problem.

One of the things that came to mind is "localy mounted file systems". We're
not sure how this works. Can we put a, let's say' 400Mb disk in the 710 and
use it for both swapping and data-storage? If yes, are any specialties needed
or can we just mount the disk on the 710 and access it transparantly?

I've been reading the release notes for 8.0 and if I read it correctly:
1. A disk can be *physically* attached to any cnode in a cluster, but
2. can only be mounted on the rootserver???
Or am I wrong on this?

And what about 9.0? Will it have this "localy mounted file systems" too? Will
it add anything to it??

Any pointers on what we could do are greatly appreciated. I'll summarize in
this group.

Many thanks in advance,

If you have a file called Vuehello in your login directory you can get rid
of the white copyright notice on a blue background. The contents of my
Vuehello file at the moment are :-

Vuehello*Background: Black
Vuehello*Foreground: Wheat2
Vuehello*Timeout: 30
Vuehello*File: /users/daniel/.welcome
Vuehello*String: Good afternoon\n\n

Then in my .vueprofile I do the following

fortune > $HOME/.welcome

Which gives me a vaguely entertaining login screen. Of course I guess you could 
set the timeout to 0. The string is generated by a cron job to give various 
different values depending on the time of the day, etc..
