The filesystem on the internal hard drive on our NeXTstation has been
corrupted. The dump program attempted to dump the drive onto itself.
Although the dump was aborted quickly, it was apparently not aborted
before the process had begun to write on the hard drive. This drive was
our boot device and, short of devine intervention, will have to be
rebuilt. At least I cann't see an alternative to rebuilding it.

Unfortunately, this dump would have been the first back-up of
the drive. We would like to back-up all of the files on the drive that
are still intact (which should be almost everything). I have two
questions:

	1) What are the chances of repairing the filesystem
	sufficiently to mount the drive? For example, would 'fsck -b'
	be a reasonable thing to try? I assume that the primary
	superblock was at least partially overwritten. On the other
	hand, this could do more damage.

	2) If the filesystem cann't be repaired sufficiently to be
	mounted (which is likely), are there any utilities that would
	allow us to copy files from the disk?


Any advice would be appreciated. If anyone knows of a worse disaster I
wouldn't mind knowing about it. Misery loves company!

Hello there,

Is there a way of using an AFGA ARCUS scanner with the NeXT ?

Does a driver (or someone developing one at this very moment) exist ?

Or maybe there's another solution to the problem ?

I use /usr/lib/transcript/psrev in a shell script as the output filter in the

and places the output on its stdout.

--------------------------------------------------------------

Here's an example that I used to test this method, and it works (thanks Colin):
First I used the Preview option in the print panel to create a .ps file.  For  
the example it created the file /tmp/.preview760088.ps.  Then in a shell, I  
used the psrev command

% psrev /tmp/.preview760088.ps | lpr -P zwicker_printer

zwicker_printer is the name of the printer used to print the stuff out.  See  
the man pages for more info. and capabilities regarding psrev.

Now for the good news.  I looked around the documentation for printing in 3.0  
(beta release) and it turns out that things CAN be printed in reverse order (in  
3.0).  The print panel is very similar to that in 2.1, but to print stuff in  
reverse order, you just use the "From" option in Pages and enter "last" in the  
"From" field and enter "first" in the "To" field.  It worked with a document I  
printed from a machine with 3.0 on it, but it doesn't work in 2.1.  So if you  
can wait for 3.0, everything should be much easier.

1.	Don't run programs that need lots of VM.
2.	Reboot.

Subject: Mounting external drives (slight clarification)
Organization: University of Victoria
Date: 15 Sep 92 13:24:59 GMT

	If you've read my "what's the scoop" post, then I should
clarify one point...

	If I telnet to the NeXT when it's at the login screen, I can't
"see" the external drives after logging in. This is typically the
situation in the evening when I'm dialing in from home to one of the
computing centre's Suns and then telnetting to the NeXT.

	But if I'm already logged in at the keyboard (and see the
external drive icons on the browser shelf), then I _can_ "see" the
external drives when I telnet to the NeXT.

	So it's like there's something different about the way the
system mounts drives when logging in at the keyboard versus logging in
via telnet...

	Thanks again for any suggestions. (Sorry for being so
long-winded. I'm sort of thinking this through as I write, which is
perhaps not the best approach...!)

	Michael.

You were using:

saying something like

This should make the sun simply copy bits to tape, rather than place
any particular religious interpretation on them (:_)).  Thus then may
make the tape readable by a similar incantation involving the NeXT restore.
If that doesn't work, something bizzare is happening, and you need to try

I thought that I flicked the non-netinfo button on the Net-info manager, and rebooted.  However, when the system comes back to life, it still gets all of this hosts info and other information from the net-info files.  When I doubled ckecked net-info manager, it was still set for non-Net-info network.  Am I missing something?

Could somebody please help me I'm going nuts!

I reviewed the man pages but didn't find an easy way to manage these files, but  
in poking around in /private/tmp I found the "monthly" and "weekly" shell  
scripts.  I ran these manually and they seemed to pare down the nasty files (my  
machine is not networked, so I don't need all the otherwise neat history in

We use a CD-ROM database that, because of its data format (weirdly
compressed, and I'm not a cryptographer) can only be used with the
DOS software it comes with.  (SoftPC won't handle this situation.)
In the past, we'd kept a PC in a corner of the office just for this
database, but we wanted to change things so users could access the
data from their own NeXTs at their desks.

Our solution -- which worked, hence this posting -- was to get OS/2
and its NFS-TCP/IP add-on and a ethernet card for the PC.  Since
IBM's OS/2 can emulate both DOS and Windows, as well as running in
normal mode as a real operating system, this had turned out to be
an inexpensive and robust solution to our problem.  I suspect it
may be a reasonable way of dealing with lots of other situations as
well, and most of us have a suitable machine sitting around or can
acquire one at little cost.

You needn't terminate the BNC connector in any way.

The NeXT will switch between 10BaseT and thinnet automatically.
One of the problems you might be having is if the site has old
10BaseT, such as an AT&T Starlan 10, that came out before 10BaseT
was standardized.

The NeXT requires Link Integrity to be on, so you'll have to check
the AT&T hub. Newer ones have DIP switches on the front that toggle
LI; turn it on for the NeXT's port. If all you've got there is old
hubs, you'll need a new one.

It's the NeXT that has standard 10BaseT; the hub is "wrong."

Reboot.
Mma is notorious for expanding the swapfile.    The only

Color me clueless if you like, but hearing this two times in
quick succession prompts me to ask what is so all-fired
awful about rebooting a computer?  Sure, with a large lab, a
complex network, or many users all engaged in important
mission-critical tasks :-), there are obvious reasons why it
could inconvenience people.  (Try waiting out the four hours
it takes to bring up a large Vax cluster from backup tapes.)

Neither above poster reveals their standaloneness, but
perhaps having lived through literally many thousand
computer crashes in which rebooting was the only option that
made any sense, I have something like a reflex that's always
telling me, "This thing could stop dead in its tracks at any
second, without warning.  Am I in the best possible position
for this unhappy event right now?  If not, get right with
the Lord of Silicon!"

An orderly shutdown and restart is certainly less of a
threat to one's future than a power failure or a panic stop.
To be sure, I watch the console like a hawk when I reboot,
half-sure that something's about to go wrong.  In a couple
years of NeXTing, fsck has run during the boot only a couple
times, and that always was the result of running some
cockamamie alpha or pre-alpha brainchild of the would-be
wannabes out there.  Like, whaddaya expect?

But booting, especially in the standalone or tiny network
case, takes a couple minutes at most and is a whole lot
better than sitting and listening to your disk seek its fool

We're supposed to be the masters of it all, eating disasters
for a light lunch and all that.

Of course, if you don't agree, well you go right ahead and

yowling you may hear.
