I am trying to get use a western digital board on my 386i in dos.

I am running PC-NFS 4.0 in my dos window (crazy uh) and am not able to
get any network activity going.  

I ran nfsconf:
	device		wd8003e
	interupt	3
	address		280
	shared mem	d000 h

Then I uncommented this entry in /etc/dos/defaults.pc:

WD8003E 280 288 290 298 irq 3       mem d000 8

Then I uncommented BOARDS in setup.pc and made it like this:

BOARDS	WD8003e


When I run pc-nfs I get the following sequence:

ksh:

Is there a ksh for the Sun?  I'd certainly like to find out
where I could get one?  I tried to build the public domain
ksh and it seemed like a real mess.

getty:

Is there a way to get getty to present a nicely organized
greeting screen (showing applications and hostname etc.)?  I
noticed that our HPucks (HP-UX) systems seemd to have this
capability.

Thanks in advance:

Subject: Can I limit the number of concurrent processes *per user*?
Organization: Eastman Kodak Co., Rochester, NY
Date: Tue, 28 Jul 92 17:14:54 GMT

I have a user who is writing a program that uses the fork system call.
I'm not familiar myself with the ins and outs of this call, but those
of you who are can probably guess what problems he is creating.  He
ends up with a gazillion copies of his program running at once.  The
only thing that limits him is the maximum number of total processes
that the system as a whole can run.

What I'd like to do (besides the obvious) is to limit the number of
processes this particular user (or any user for that matter) can have
at any one time.  Can it be done? I know maxusers can limit the size of
the systems process table, but is is possible to limit individual
users?

Thanks for any help.

Look at the man pages for cm_insert, cm_delete, and cm_lookup.
They're in there.  I've never used them, but I assume they work.
They're simply tty interface programs to the cm

Hm.  I'm pretty sure we did -lresolv also; did you maybe replace yours

A friend is about to connect a Seagate Wren VII (ST41200N) to his system
(running SUNOS 4.1.1), and we are wondering what parameters are best to
use when formatting the drive.  The data sheet for the drive mentions that
the drive has an unformatted capacity of 1.2GB, a block size of 512 bytes,
1931 cylinders, and 15 heads.


So what opinions do you, the people of the NET, have?

A format.dat entry would be fine.

|Your dump parameters are fine.  RTFM the sections on st:  under 4.1.2,

I just got off the phone to our Exabyte drive suppliers technical
department, according to them using /dev/rstn+8 for 5GB density is fine,
as long as the tape is new. If your tape has been used on an Exabyte
8200 unit the new 8500 drive will continue to use the tape as a 2.3 GB
tape.

I disagree. The idle time should be adjusted by SunPro to ensure that the
number of licenses you buy accurately reflects the number of users. It is
impossible to do this perfectly (some will have to buy more than is 'fair'
and some will be able to get by with fewer) and you can often get around
it (by setting up a 'make' daemon) but basically you should expect to have
to buy a number of licences that reflects the number of compiler users.

Personally I think this is one of the few sensible things Sun have done
concerning the new compiler.

|> I believe we will be looking for other vendors to supply out compiler needs.

Fine. Try gcc, then you get a debugger that doesn't hang when you start it,
doesn't take a SEGV when your program takes a Bus Error and (last but not
least) can be relied upon to find the source files for your code instead of
forcing you to learn SPARC assembler :-) I *HATE* dbx. Neil.

That's the default route for IP multicasting.  Note that it's a Class D network
number.  IP multicasting is described in RFC1112:

1112  Deering, S.E.  Host extensions for IP multicasting.  1989 August; 17 p.
      (Format: TXT=39904 bytes)  (Obsoletes RFC 988, RFC 1054)

It should make for some interesting applications, once enough vendors pick it
up (I've heard Ultrix has it as well, but don't know for sure).

There is a Wren VII entry in the distributed FORMAT.DAT
file with SunOS.  You just need to uncomment it.

HOWEVER - I have found that some RECENT VII's won't work with
Sun's distributed file.  Apparently SEAGATE made a couple
of firmware changes and the number of available sectors is 
slightly smaller.  If you have trouble with it just take a
couple of tracks off and you should be fine.

Also -
	You may find you have some trouble with this depending on
how you're using the disk.  Early VII's don't work as boot
disks on machines with the new OPEN BOOT PROM (typically ELC,
IPX, and SPARC 2 machines, etc.).  You get some nonsense
about not being able to read the partition table, etc.
There is an ugly fix for this.  If you end up needing it let me know.

Ignore it.  Newfs just tries to use sectors in groupings and one sector was

According to the EXB-8500 Users Manual the 8500, when positioned at
PBOT will write at whichever density you tell it to.  Under SunOS
4.1.2 the tape devices /dev/{r,nr}st[0-7] are 8200 format and
/dev/{r,nr}st[8-15] are 8500 format.  More information is available
from 'man st'.  If you write to an EXB-8500 anywhere but the beginning
it will ignore the density setting you tell it and will write at the
same density the rest of the tape has been written at.

Under SunOS 4.1.1 and below there is no support for 8500 drives which
is why it will write 8200 format if the tape was already written.  I
believe that if you don't tell the drive what to do it assumes that
you want to use the format that is already on the tape.

|I've been having very simlar problems, last nights dump failed with-
|  DUMP: dumping (Pass IV) [regular files]
|  DUMP: Tape write error 10 feet into tape 1
|  DUMP: fopen on /dev/tty fails
|  DUMP: The ENTIRE dump is aborted.
|
|I've had this happen before (oddly enough its usually 10 feet into the
|tape) so I usually redo the dump by hand when I arrive in the morning
|and it works! I've tried cleaning the drive but it doesn't seem to do
|anything.
|I'm about to rewrite the dump scripts so that they reposition the tape
|and have another go if they fail.
|I also see occasional errors logged to the console:
|
|Jul 24 03:05:42 orion vmunix: st1:  I/O request timeout
|Jul 24 03:05:42 orion vmunix: sm0:  target 5 reverting to async operation
|Jul 24 03:05:42 orion vmunix: sm0:  resetting scsi bus
|.......
|
|although this last one is the first to actually coincide with a tape
|error.

Well I just got off the phone, the answer from our suppliers technical
department is that the Exabyte 8500 are not supported fully under SunOS
4.1.1 (and yes he knows about the hack to stdef.h to enable us to use
different densities). It seems that the Exabyte uses a SCSI-2 interface
which, in certain circumstance, does a SCSI disconnect when its busy, so
it frees up the SCSI bus for other devices. As SunOS 4.1.1 doesn't
understand this disconnect it sometimes causes a SCSI reset, it seems
that at other times its just causing a tape error. It seems that if you
don't want problems upgrade to 4.1.2, unfortunately I don't think that
we can.
