We have a poorly documented card-cage in our 4/370. We notice that we
have an si0 SCSI controller in addition to our sm0. The sm0 has been
used for disks as well as for the two 8mm tape units we have on it.
To make a long story short, we want to move the Exabyte tapes to si0
and free up sm0 for disks for hopefully better bandwidth.

There are two seemingly connected "D" ports on the back suggesting
that we can use the si0 interface for more than just the internal 1/4"
tape (which by the way won't boot the machine currently). But how?

Configuring a kernel for the si0 port to handle tapes gets strange
results: the kernel tries to write to them, but just can't.  Any
ideas? I think we have a strapping issue here, and I'm almost afraid
of the answer...

Thanks!

This is one of my old favorite bugs in the 4.1.x rpc.yppasswd. What happens
is that all strings to be entered in the password file (gecos/shell/password)
are checked to enforce a maximum field length and to disallow
certain characters. When a password is entered in the password file
with the yppasswd protocol, it is transmited in an RPC request containing
the old password (in cleartext) and the new password (in crypt(3)) encrypted
form.

What yppasswdd should do is check the old password with the password
in the password file and allow or disallows the the change.

What yppasswd does, is check the oldpassword with the string checkroutine
(this is a routine that takes two parameters: a string and the max length)
If the password contains a ':' or certain other characters, the string
decode routine will refuse to decode that string and the RPC request will
fail. I was luck enough to find a version of the yppasswdd jumbo patch that
wasn't stripped and nopped out the calls to that routine (when called
for the password).

As you see, yppasswd never sees the new password in cleartext and allows
passwords to be entered in the passwd file that it will refuse afterwards.

In /etc/ttytab, you should specify ``on remote'' for the modem lines,
rather than ``off local''.  (Actually, any string except ``local'' will
do it.)  Then, the ttysoftcar command in /etc/rc will set those lines
to respond to the DCD signal from the modem.  You also need two hardware
signals, DTR and DCD, in the wiring to the modem, and the modem must
be configured to use those signals.  When a user logs out, the ALM-2
will drop the DTR signal, and the modem should then drop the connection.
When a user disconnects, the modem will drop DCD, and the login shell
should receive an end-of-file and terminate, so that init starts
another getty on the line.

Subject: How to manage backups in a multi-vendor network
Date: 5 Oct 92 17:09:02 GMT
Organization: SEKAS, Munich, Germany


I have recently become administrator for all UNIX machines at our
company. Up until now, there was no coherent system management
for these machines. Each user was more or less responsible for
making backups of his work himself.

I would like to change this and start a regular backup scheme and
would appreciate some help from people who have similar setups.

So far we have one Sparc Station 2, an HP machine with HPUX 8.0 and
several Interactive PCs. The only medium for doing large scale
backups we have, is an Exabyte tape, which is connected to the
Sparc Station running SunOS 4.1.2.

The first problem I encountered is, that appearantly the SunOS dump
command can only be used to back up ONE file system on one tape. Is
this realy true? If so, the dump command is out already, since there
are four file systems on the Sparc alone, and I don't want to stay in
the company every night to switch tapes.

Otherwise, the dump command would be at least a partial solution, since
one can use the remote tape interface. I say partial, since Interactive
UNIX appearantly doesn't feature the remote tape interface.

Now for a completely different approach I thougth of: mount all the
file systems in our company over NFS on the Sparc (all our UNIX boxes
have NFS) and do a

	tar c /

Is this workable? Does tar do the right things with special files,
hard links, symbolic links, ...? Does it work on NFS mounted disks?

Any answers to the above questions or all together different solutions
would be most welcome!

Hi there,
I need some help getting my 4/110 to use the mono frame buffer for
text mode (like when you reboot or startup the machine, the initial
character mode that the display is in.)

Right now it is using the color framebuffer (I have the combined mono/color
framebuffer board...)
It works fine, but it is VERY slow at scrolling text.
My 3/160 was faster at scrolling than this 4/110 is because it only
used the mono framebuffer.

I have the eeprom field for console set to  b&w  but it is still using 
the color framebuffer...

PLEASE any help would be appreciated, the current scrolling rate is insanely
slow!

I have a question. I am trying to track VM usage on a SS2. I don't think

are 0. However, there is an entry in vmstat called "fre" that shows the
VM free size list. What exactly does this mean. It seems that when the

when none is being used?

Also, no flames about this being elementary CS stuff... I have never had

I need correct syntax info on how to boot from tape for Sun-3/160.
Unfortunately My experience lies within the Sparc 4 family, and about
as kinky as i've had to get was when booting from a Sparc 1+.  Which
always booted from sd(0,6,2) via cdrom.

Pertinent Info:     --Sun OS 3.0B (*trying to upgrade to 4.1.1*)
                    --Sun 3/160
                    --Using the Internal Tape Drive to Boot
                    --No External Drives of any kind.

Equiped with what little rusty knowledge I possess, I have tried the
following.

------b sd(0,4,X)XXXXX  Makes assumption that Drive is Target 4.
                        Not Certain about Part # but have tried
                        the following Combinations ---b sd(0,4,2)

                        Attempted 32 since Slave device was listed
                        As such.

Am I wrong to assume that the Drive is Target 4 ???  I have tried various
Combinations assuming other target numbers but to no avail ...

HELP!!!!!!!!!!!!!!!!  Any Assistance is GREATLY appreciated.

Also Curious about how to make a boot tape for this machine.  Can I get
away with merely using dd to copy vmunix over to tape, or do I need to
dd boot out to tape in such a manner that it precedes vmunix?  Or is there
anything else I'm missing ...

This happened to us once, when we called the supplier they told
us that this is a "return to service center" problem.  After convincing
them that I knew what a screwdriver was, I got the following information:

	1) remove cover from drive (ours is in its own shoebox)
	2) one the left hand side (looking from the front), there is a
	   little white lever/catch - gently press it forward until the
	   tape releases.
	
At this point they suggested trying the tape again and seeing what
happened...  we threw the tape away instead.

SunOS 4.1.2 (and 4.1.3) get you to 256. By default, this is reduced to
64 by the resource limits; in csh, type "limit" to view the limits,
and "limit des unl" to raise the descriptor limit to its maximum value
of 256.

Subject: Configuring an ALM-2 for autobaud and disconnect
Organization: Acadia University
Date: Mon, 28 Sep 1992 22:19:02 GMT

We have a 16-port alm-2 terminal board for our Sun-670 and want
to set it up so that it can be used both for direct connections
from dumb terminals at 9600 baud as well as dial in connections at 
1200, 2400, and 9600 baud. Additionally, we want to configure it
so that when a user logs out, the line disconnects, and when
a user hangs up without logging, the user's session should be
terminated. As it is now, if a user disconnects in the middle
of a session, the next person that gets the same line enters
in the middle of the previous session assigned to that line.

From what I can gather, the file /etc/gettytab has to be
modified to achieve the behaviour we want, along with the
file /etc/ttytab. I've defined the lines as Auto-baud in
/etc/ttytab, and have no problem connecting at 9600 baud.
Lower baud rates do not appear to set up properly. Also,
the lines do not disconnect on a hang up as we want.

Does anyone have any suggestions what needs to be done
to achieve what I've described here? Thanks in advance.

In typical Sun fashion, I believe that Sun Consulting has a fix called

we had to acquire it for use with our Sparcstations driving USR Courier

The "segkmap" patch only applies to the Sun-4M kernels. It *could* have
