I was told by a Sun instructor in a 4.0 administration seminar that if you
were going to mix 4.0 and 3.x machines in a YP domain, you better make
sure that the slave and master servers and 4.0 machines.

Subject: Re: VME Bus Errors on the Sun4
We were having a number of problems porting support for our array
processor products from the Sun3 to the Sun4. The problems all centered
around moving floating point data to/from VME bus memory. The symptoms
when moving single precision data varied from storing incorrect data to
Bus Error messages. This is all to/from a 32d32 device.
Sun has produced an ECO #4314 which brings the Sun4 cpu board to rev 13.
This took several iterations, but appears to fix all the problems moving
single precision data that we know about.
However, there remain problems with moving double precision data. The
symptom is Bus Error. The problem happens only when moving 8 byte aligned
data because the compilers generate ldd/std instructions.
Sun has stated that they don't plan to change the hardware to fix this.
Instead they will produce a software fix - they won't generate ldd/std
instructions from C or Fortran unless they are references to the stack, or
the user has specified a switch saying 64 bit accesses are ok. They will
also recompile all math libraries in this mode, so they never generate
ldd/std instructions. This will be released at some as yet unnanounced
date in the future (SunOS v4.1, Fortran 2.0).
This means that all Sun4 customers will see a performance hit, whether
they have vme memory devices or not. I don't know what the actual
performance difference will be, however.

Subject: Re: .cshrc vs .login
I disagree with the advice given here that setenv variables go into your
.login. This will cause the following alias to work incorrectly.
alias rxterm 'rsh \!* -n "xterm -display `hostname | sed s/\.clarkson\.edu//`:0.0" &'
This is used to start another Xwindow on a remote host. If I put my
setenv's into my .login this would fail. The only thing that I use my
.login for is to do a few stty's set my terminal if I am on a dialup line
(I do not use tset, it is cursed) and print a few things of interest such
as the process load of the machine.

Subject: Mail Notification: "plug-compatile" biff
We had a similar problem on our network of Suns. Our solution was to
provide a plug-compatible 'biff' which basically sat around watching the
mailbox.
People who now use X11 (a rapidly growing community here) just use xbiff
instead.

This is probably because root has a normal shell but the user has some
shell that is not /bin/sh or /bin/csh. The 4.0 ftpd is based on 4.3BSD
and it expects the file /etc/shells to have a list of the valid normal
login shells if the system has alternates. These days, common alternates
are ksh and tcsh. See the man page on getusershell(3) for details. By
the way, /etc/shells was long overdue.

Subject: SUN INR 5.0 Weirdness
Users of SUN INR 5.0 router code under OS 3.5, have you seen this totally
bizarre problem ? We have a fairly complicated internal network here, one
of the solutions we implemented for connection of remote sites to the
internal backbone nets was to use SUN's INR with 9600 baud sync modems
attached to 3/50's for use as routers. This provided remote nets with
access to the internal nets, Internet etc. However, some TCP connections
were being reset due to timeouts with the remote host when using an INR
route. Analysis revealed that the INR will not send an IP packet of
exactly 108 bytes through from one side to the other. When a IP packet
arrives that is 108 bytes in length from the Ethernet side, it is digested
by the SUN. The remote router never sees this packet, as first the router
never sent it along over the serial line. For TCP connections, this meanes
that the sender never has this packet ack'ed, retransmits n times, sees no
ack's as the remote has never seen anything to ack and then resets the
connection, assuming that the remote host has died. Cute, eh ? Some
peripheral information, changing the MTU on these lines to prohibit/force
fragmentation, netmasks, trailers etc has no effect. The same problems
occur on a subnetted Class B net as on a Class C or Class A. We have also
run up an down in packet size, no other sized packets fail to get through.
SUN has no idea, says that they are unable to reproduce this weirdness;
anyone else seen this ?
Thanks in advance

Organization: Computer Science Department, The Pennsylvania State University
333 Whitmore Laboratory, University Park, PA 16802
Phone Number: +1 814 865 9723
Description:
Netstat appears to not understand sub-netting correctly. At Penn State we
are using the Class B network number 128.118 with sub-nets. If 'netstat
-r' is run on a Sun4 running SunOS4.0 all sub-nets of 128.118 are reported
to be 128.118. This works correctly on a VAX 11/750 running 4.3 BSD UNIX.
(Sigh... will Sun ever get these things right?)
The ethernet interface on the Sun4 is configured thusly:
SUN4% ifconfig ie0
ie0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
inet 128.118.6.4 netmask ffffff00 broadcast 128.118.6.0
Running 'netstat -r' one gets:

This is a first time sending a request for information, so please bear
with me. We have a Sun 3/160 C-4 with a 71 mb SCSI drive. We would like
to add an SMD drive to avail ourselves of the larger disks. Can anyone
tell me what we need in terms of hardware for connecting one and what one
has to do to get the XYLOGICS controller to be known to the system. Also,
where would we obtain a formatter tape for such a disk. This is
information needed should we choose to purchase from other than our Sun
dealer. We are currently running 3.2 on this system. Any information
will be greatly appreciated. Thanks.
