I have a SS2 with two SCSI adapters (esp0 & esp1).

esp0
 |
400MB internal disk
 |
8500 Sun exabyte drive
 |
1G external disk.

esp1
 |
8500 Sun exabyte drive
 |
1G external disk.

The problem is when I try to do ``copytape'', ``dd'' or ``tcopy'' from
one exabyte to the other I get the following messages on my console and
in the /var/adm/message file:


Aug 18 15:37:54 quantum vmunix: esp0:	Target 4 now Synchronous at 4.0 mb/s max transmit rate
Aug 18 15:38:59 quantum vmunix: esp1:	Target 4 now Synchronous at 3.572 mb/s max transmit rate
Aug 18 15:40:59 quantum vmunix: esp0:	Target 4 now Synchronous at 4.0 mb/s max transmit rate
Aug 18 15:42:53 quantum last message repeated 28 times
Aug 18 15:46:23 quantum vmunix: esp1:	Target 4 now Synchronous at 3.572 mb/s max transmit rate
Aug 18 15:46:31 quantum last message repeated 17 times


The above is repeated over and over until the ``command'' is finished.
The copy to tape seems to be ok but the system comes to it knees during
the copy.

The problem happens no matter which direction I am copying. 

I have no problems if I am writing to both tape drives from differend
programs.

Any answers to this problems.

Thanks

Here is the inetd.conf entry for tfs I use:
tfsd/1-2        dgram   rpc/udp wait    root    /usr/etc/tfsd   tfsd

Example:
   mount_tfs /usr/opt/URANIUM /src/uranium

To overlay /src/uranium (the existing, r/o filesystem) with /usr/opt/URANIUM (r/w).
This will create file .tfsinfo in /usr/opt/URANIUM (if it does not already exist)
and will  create two loopback mounts and one tfs mount thus:

   / on /tmp_mnt/Tfs_native type lo (rw)
   /tmp_mnt/Tfs_empty on /src/uranium type lo (rw)
   /usr/opt/URANIUM on /src/uranium type tfs (rw,timeo=50,intr)

Which 'top-directory' are you doing your 'cd' to?   In the example above, 
you would 'cd' to /src/uranium as usual, not to /usr/opt/URANIUM, which
will remain empty (except for .tfsinfo) until you attempt to add or modify a file
in /src/uranium or until you access a directory under /src/uranium.

Your users and your applications are not supposed to be concerned that
a tfs mount exists.  You access the files as you would if the tfs mount
were not there.  The difference is, if you modify or add any files, the newer
files are written into /usr/opt/URANIUM, and they 'overlay' any existing r/o files
under /src/uranium until you do a umount_tfs.

>I fear the problem has to do with the automounter which isn't enabled at our site.

Automounter is not required.

I've noticed this behavior on several Suns which were using "swapon" to
split swap space among several disk partitions. Unfortunately, I don't
know if there is a fix and if so, if it's one of the fixes you've already
applied. (Maybe someone else could help?)

Might this be the problem you're seeing?

Yes, we are. Heterogeneous Sun/HP configuration, Sun NIS master, only Suns

We had some problems when we started using 100482-02, but it's working
fine now. The problems were only caused by misunderstanding the format
of the /var/yp/securenets file, and we found these by inspecting the
log files (/var/adm/messages) on our loghost.

I don't have any good idea of what might be causing your problems. It
works for us...

If you set it up badly, it isn't restricted at all. Take the following
precautions:

set the path to a separate directory containing only those commands
needed. In your example 'more' was in the path. More isn't unsafe, it
exec'ed the program via the shell, hence '/bin/csh' was restricted,
but 'csh' wasn't. You probably put '/bin' in the PATH, which means you
could just have typed 'csh' as well. Don't give the user unsafe
commands, like a real shell, vi or cc, for example.

Make the user's home directory owned by root, and unwritable. Also
do the same for the .profile.

In general, /usr/lib/rsh isn't that restricted. There are lots of tricks
to break out of it. It's a seventies idea that has long been outdated.
Try a custom-written C program as shell that doesn't allow exec's or
shell escapes.

When trying to print to a SparcPrinter from a Macintosh using a commercial PAP spooler, you need to backoff your laserwriter driver to 7.0. 7.1 and 7.1.1 do indeed fill up tmp.

Summary: How to configure two NC400 onto one Ethernet
Keywords: NC400 Ethernet TCP/IP 
Organization: Ascom Autelca AG, Guemligen, Switzerland
Date: Fri, 21 Aug 1992 07:23:52 GMT

Hi there,

I have a question regarding two NC400 in a SPARCserver 4/690 (Solaris 1.0.1 or
SunOS 4.1.2).

Is it possible to configure the two NC400 and the Sun, if both NC400
ethernet boards are accessing the same physical wire (10Base2)?

As I know, both boards will have the same ethernet MAC address (downloaded by
software, not fron an EPROM), but will have different hostnames or IP
addresses. I assume that this will produce some arp/rarp conflicts because
two IP addresses will have the same ethernet MAC address.

The installation guide to the NC400 only shows a multihomed server with an
ethernet segment per NC400 board.

Our ethernet is not designed to split it up into segments (in fact it's
poorly designed but don't flame me...)  :-(
There is just one way we could use two segments, but there is a little
problem. At the moment this two segments are bridged. Some PC's are
accessing an IBM AS/400 over LU6.2 encapsulated into raw ethernet frames
through this bridge. In addition there is some EtherTalk and IBX/SPX traffic 
through the bridge. 

If I would replace this bridge by the Sun (including the two NC400), would
this connections (EtherTalk, encapsulated LU6.2, IPX/SPX) still work over
this Sun? I assume no, since there would have to be some bridging
capabilities between the NC400's...

Who could me tell more?
Has anybody some installation hints for us?

Thanks for any hints in advance...

Daniel

A question on setting up a LaserWriter II for use on a Sun ...

My Problem:
I'm trying to set up a LW IIf for shared use between Macs
(all running Sys 7) and our Sun (running 4.1.2). When I
try to print a PostScript doc from the Sun to the LW, the
'busy' light flashes but no output is produced (the
same doc prints ok from a Mac). My /etc/printcap seems
ok - when I view the output sent by lpr on a terminal attached
to the printer line nothing looks amiss. For now, I'm only interested
in printing PostScript files on the Sun, plain text can wait.

My Question:
Does the LW require some sort of set-up job like LaserPrep
(which is automatically downloaded on a Mac) before a print job?
If so, can someone give me some pointers on where to find this
info?

Has anyone run across Newsprint2.0 Rev B's latest bug?  Don't install
it on a Sparc2 unless your cache chips are manufactured by LSI, as AT&T
chips will cause the kernel to Data fault the lpd process.  We haven't
been able to determine what the manufacturing dates are of Sparc2 CPU's
that fail, but they appear to be in the middle of the manufacturing run.

I've been in touch with numerous people at Sun and it seems this bug
will not be addressed in future Newsprint releases.  Instead, we are
encouraged to purchase a CPU board upgrade (at $430 a pop), or downgrade
our version of Newsprint to 1.0.

For those of us with third party maintenance, due to ever increasing Sun
maintenance prices,  this could get expensive!

We have nine Sparc printers on our network, eight of them are served by
Sparc2s.  And, unfortunately, Newsprint 2.0 Rev A has a really tedious
bug that manifests itself when Macintosh's try to print.  Newsprint's
eehelper process creates a file that grows and grows until /tmp is full.

What's happened to the Sun I knew and loved?  It appears they have grown
up to be yet another 3-letter computer company...

	I'm wondering if anybody has a suggestion on a problem I have with
the way my network of Suns is currently configured.  We have a central
machine which receives most mail and stores it in a mail spool directory
which is NFS mounted from about 35 other Suns.  This allows people to access
their mail from any machine on the network.  Likewise their home directory,
(just about all of those 35 machines) is (auto) NFS mounted on the server
and other machines on the network.  My problem is that whenever mail for a
user comes in; the server machine has to automount their home directory in
order to determine if they have a .forward file.  This is particularily
annoying when a mass mailing occurs, because then the server goes off and
automounts all the home directories of everybody in the department.
Eventually the automounts go away, but it seems to me to be a waste.  Any
ideas on how to avoid this while still retaining a central mail spool
directory?

This is SunOS 4.1.2, in earlier versions it is there but commented out (look for .\" at the beginning of the line).

While netgroups may be specified in access, it is regrettably not possible
to specify them after root=.
Have a look at exports(5): ``client'' means that either a hostname or
netgroup may be specified, ``hostname'' means hostnames only are valid.
IMHO, exportfs should be rewritten to allow netgroups also be specified
in root and rw.

Basicly, you don't.  The no rewind device is what this job calls for, and if
you aren't willing to use it then there is no solution.

Consider this:  After you dump the first file to the tape (and it rewinds
since you aren't using the no-rewind device), then *something* will have to
skip to the end of file mark.  Does it matter if a program does it or if you
write some shell script that uses mt to do it?  

As long as you always back the machines up in the same order, you shouldn't 
have to worry too much about keeping the dumps straight.
