sendmail is running as root when it looks for a .forward file. The NFS
server code maps userid 0 to -2 on incoming requests unless you patch the
kernel to change that feature. Thus sendmail running on a client does not
really have root access to files on the server. Hence it can't find
.forward in a protected directory.
If all clients are administered together, and you trust anyone who is root
on any client to be root on the server (remember, a user can become root
by aborting the machine and booting it single user!) then you can patch
the kernel variable "_nobody" to be 0 instead of -2.

I don't know if later versions have it corrected, but in SunOS 3.4, if you
"exec suntools" on a color 3/110, the next time you login you get some
sort of selection_svc error and weird behavior on the cgfour (i.e., Prism)
frame buffer.
We asked Sun s/w support about it and they said to avoid doing "exec
suntools" on a color 3/110. I don't know if the same applies to color
3/60s (they also use the Prism frame buffer).

I found this bug when compiling my PostScript(-like) interpreter to the
Sun 4 quite recently. A work-around is to use:
cc -Dfloat=double
to make everything double. It doesn't significantly increase memory usage
or CPU time. You may also have to put the VARARGS fixes in that were
posted sometime ago.
Everytime I port my interpreter to a new machine, I find at least one
compiler bug. A number of machines have compilers that are so badly broken
that it would take a major effort to make PS work on them. Oddly, RISC
chips seem to have been more prone to these problems. Floating point and
structure passing tend to be the major offenders.

For various techno-religious reasons, GNU Emacs is not in the public
domain, but it is free. You can get it via anonymous FTP from
prep.ai.mit.edu, or via anonymous UUCP from osu-cis. Write me for
instructions if you're interested in the latter.

Subject: SRI-NIC now supports rfc access via mail.
[[ Mr. Campbell sent this in: it is an automatic response from the NIC
describing how without ARPANet access can obtain RFCs. My thanks to
others who have also sent in the text of this message. --wnl ]]
RFCs are available via electronic mail from the NIC. To get RFC 877 from the
NIC send a message to SERVICE at SRI-NIC.ARPA with the command RFC 877 in the
subject line of your message. Here is some information about using SERVICE.
NIC Mail Services June 1988
This is an automated service provided by the DDN Network Information
Center. It allows access to NIC documents and information via ordinary
electronic mail. This is especially useful for people who do not have
access to the NIC via a direct Internet link, such as BITNET, CSNET
and UUCP sites.
To use the mail service, send a mail message to SERVICE at SRI-NIC.ARPA.
In the SUBJECT field, request the type of service you wish followed by
any needed arguments. The message body is normally ignored. Large files
will be broken into smaller separate messages. The information you
request will be sent back to you as soon as possible.
The following services are currently available:
HELP This message; a list of current services.
RFC nnn nnn is the RFC number or the word INDEX.
IEN nnn nnn is the IEN number or the word INDEX.
NETINFO xxx xxx is a file name or the word INDEX.
SEND xxx xxx is a fully specified file name.
HOST xxx Returns information about host xxx.
WHOIS xxx Returns information about xxx from the WHOIS service.
Use "WHOIS HELP" for information on how to use WHOIS.
Example SUBJECT lines:
HELP
RFC 822
RFC INDEX
NETINFO DOMAIN-TEMPLATE.TXT
SEND IDEA:IDEA0002-00.TXT
HOST SRI-NIC.ARPA
WHOIS LOTTOR, MARK

Subject: SCSI drivers
Netfolk,
This question comes up often enough that I thought it appropriate to
respond to Sun-Spots. Sun Consulting Services (a part of Sun Customer
Service) sells a generic SCSI driver called CONSULT-SIP, and the
documentation needed to modify it. We are also available to do the
modifications for you on a time and materials basis. In addition to the
generic SCSI driver, we sell drivers for various floppy, WORM and CDROM
drives. Consult Lisa Ventresca at 415-336-2438, or lisav at sun.com for
information and datasheets. (We have other specials and services available
too...)
Now, for some generic comments on SCSI - Sun supports what it sells, but
many drives are known to work. For devices other than tape or disk, you
will probably require SIP to get started. Sun hasn't documented the lower
level driver interface for SCSI host adaptors as it has been subject to
change as we adapt to new drives and host adaptors - hence the CONSULT-SIP
driver as a by-product of Consulting Services' porting effort.
Considering that it requires no source license, and has 90% of what you
need for most devices already done, it is quite a deal.
l & h,
kev

Subject: Large kernel boot problems + fix
In sun-spots of July 22, Joe Angelo talks about a problem with booting
large kernels. I thought I would elaborate on the underlying problem,
since we encountered and solved it ourselves.
The problem is when (text+bss) > 0xA0000 (= 640K). This is the start
address of the boot program as speicified in its a.out->a_entry field. If
you have source, go into the directory /src/sun/sys/sunstand and change
the BRELOC macro definition in Makefile.sun3 and rebuild boot. We use
0xB0000, which gives an extra 64K of space. This has been sufficient for
our needs. If you do not have source, I suspect that a simple patch to the
executable with adb would be enough. The BRELOC is only used to determine
the entry point in the "ld" statement during build.
BTW, there is supposed to be some checking for this during the boot
procedure, but that checking seems to be broken. Probably an off-by-one
error counting the required pages.
This fix *WILL* allow use of GENERIC kernels, as it doesn't really change
anything except what address the booter gets loaded at. I don't know what
SUN did for their fix to affect this. This fix has been running here for
some months now, without incident, but does not come with any sort of
warranty.

I am coordinating my research group's purchase of a SUN4 (two, hopefully).
Right now I am looking at buying a system from Artecon, principally for
their lower prices on disk storage. Has any one dealt with them and what
were your experinces like (good, bad, indifferent)?
Also, does any one have experience with the new 8mm catridge tape drives.
Do they really work? Certainly back-ups are a lot easier (not having to
change tapes) but can you reliably restore from the tapes?
Please reply to the address below.

If you have read my previous message, I think I said that I like to know
