This is bunk.  The SCSI bus is driven by open-collector devices.  A 
properly behaved SCSI peripheral may be left in the powered down state without
any ill effects.

SCSI signals are not passed through a SCSI device.  Rather the bus is
tapped by each device on the bus.  This is why it is called a "bus".
Quite often the terminator power comes from the host, not the drive.  This
is true of *both* the near and far terminators.

This is good advice if for no other reason than you may choose to power 
up a device at the same time then NeXT decides to swap or something and
who knows how well behaved a device going through power up is.

Hi,

I would like to write  a script that will ftp files from a machine here on my  
campus.  The files are generated on a weekly basis and also on a monthly basis.   
I would like to have the script run from cron and then take care of the  
login,password, work it's way through the directories,"get" each of the files  
and then send me a mail message with the results.

DO any of you have a similar script that I could have so that I don't have to  
write it from scratch?

Please drop me a line if you do.

Thanks,

Since I've had a few requests, I will be compiling the mtools and put them
on sonata and cs.orst. There will be the sources and binaries or those who
don't have the extended system. The binaries will be for the internal drive
only.

	I will probably do that late tonight, Pacific time.

	The mtools are a series of programs to read, write, copy and generally
access files on DOS formatted disquettes in Unix workstations. The command  
syntax is more or less equivalent to their DOS counterpart, like
copy foo a:bar
They are much faster than the workspace, or, from what I've seen from this
thread, equivalent capabilities on Suns.

Hope it helps,

Lga.

Date: Thu, 23 Jul 1992 04:01:52 GMT

I pass news to a NeXT system via a 9600 baud v.32 dialup modem connection.
Typically, I expect to get ~850 bytes/sec throughput using uucico.  However,
on systems which insist on using the old uucico default of 3 for a window
size, this throughput drops to about 700 bytes/sec.  This is what I
see when talking to the NeXT.

I know very little about this machine and operating system.  However,
I would like to minimize the modem connect time.  Various patches have
been released for different versions of uucico to increase the window
size to 7, and thereby increase the 9600 baud thruput.  Newer uucicos
even allow specifying the window size in the Systems file.  I am not
familiar with the NeXT, and none of the mechanisms I have suggested
appear to work with its uucico.  I would be grateful if someone could
tell me how this can be done.

Please respond directly to me, as I neither own a NeXT, nor read this
newsgroup on any kind of a regular basis.  Thanks in advance.

In the passwd file, you must have lines like:

It is supposed to be in HIER(7), but all that is there is a terse note from
NeXT saying to "see the NeXT Operating System Software manual".

However, the NeXT Operating System Software manual has no such information, and
it appears to refer the reader to "the on-line UNIX manual pages" for this sort
of information.

How's that for RTFM?

I recently started having a similar problem.  I attached a Bernoulli  
Transportable 90 drive to my NeXT and used it for a couple days without  
any trouble.  The trouble started when I tried to eject the disk.  The  
manual says to drag the disk icon to the Recycler and only to press the  
drive's eject button when the disk disappears from the File Viewer.  Mine  
wouldn't.  I couldn't figure if the manual was wrong or what but, being  
impatient, I finally pressed the button.  The disk icon stayed... it  
stayed when I logged out and back in even.  It only went away when I  
turned the NeXT off and then on.  I put the Bernoulli disk back in and  
everything seemed fine.

Then next day I found the hard disk was full.  I had 100MB free the day  
before.  I poked around a little looking for what had grown so huge but  
then thought of the Bernoulli disk.  I ejected it (same problem as before)  
and then turned the machine off and on.  And there was now 100MB free.  I  
put the disk back in and there was a sudden drop to 65MB.  It seemed to  
stay there so I didn't worry too much.  I came in the next day and again  
no space on the hard drive.  Again, I ejected the disk (it worked right  
this time!) and restarted the computer and the 100MB was back.  I put the  
disk back in for a short time but the HD space dropped to about 80MB so I  
ejected it.  All day the space on the HD has steadily dropped.  Now its  
45MB and dropping.

The above posting sounded strangely familiar and so I checked my  
/private/vm/swapfile.  It is 58MB and seems to have grown since the last  
time I checked.  Maybe something else is going on but there seems to be a  
connection between this device and the HD space.  I'm stilling waiting to  
hear from Bernoulli but thought someone else might have a suggestion...

Anyone that is going to steal a next probably already knows how to remove the  
rom password.  You do not even have to take the battery out for an hour or so.   
You could wipe out the password in a matter of seconds.

I like your meaning of NFS (No File Security) Its not just NFS that has some  
major holes. I know someone (not me) that has found a way to gain root on almost  
any NeXT, even without an account on the machine.  It was submitted to NeXT  
(because it is actually pretty simple) I hope that they fix it before 3.0 ships.

I've followed all the directions that came with the SLIP 920506
package and I'm running 2.1 extended and using Mamakos' SLIP package
(nice package by the way).  When I get the proper IP address and
complete host name (all four parts of the name, not just the first) in
NetManager and reboot, SLIP comes up and connects with the SLIP
server.  But then the windowserver says it's sleeping and then it says
it can't find a port.  SLIP, meanwhile, seems to be connected fine and
doing some data transfer (I can see both send and receive lights
flashing) of some kind.  I don't know what it's trying to do.  I just
get continuous messages saying windowserver is sleeping or it cannot
find some port.  I never get a login window.

Also, before any of this happens, the machine puts up the 'can't find
parent NetInfo server, press 'c' to continue without parent server'
prompt, even though i configured the machine (in NetMgr) to be a
non-netinfo machine.  If I hit 'c' it continues up to the point I
describe above.

Could someone help me to get SLIP running?  Any help you could provide
will be most appeciated.

Thanks.

Then, after 3 hours (I don't know if someone ever changed it), the mouse

Is it possible that because I didn't protect something properly (say, chmod

	Well, the DOS filesystem on the NeXT *is* slow. So slow that you 
shouldn't use the workspace to transfer files on DOS disks. You should grab 
the mtools from the net. They are infinitely faster. 

	I've heard that the problem is fixed in 3.0, although I may be
dreaming.

Yes, that was the problem (although my wife and I could have sworn
that I hit non-netinfo network).  And thanks for the response.

I'd also like to thank two other people, they know who they are, I'm
not sure broadcasting their addresses is a wise idea (I never received
explicit mail from them saying I can do so and I wouldn't want them
having to fend off tons of other people seeking advice).
