...We were told that the rack would need a 110-volt 30 amp circuit...Lo
and behold, what appeared was a rack which requires a 220-volt, 30 amp
circuit!
I suspect someone screwed up in Sun's configuration department. You
should have gotten a power supply that only needed 115 volts. We've got a
Sun 4/280 with one Hitachi and tape drive which has the reportedly correct
power supply (115V, single phase, 60Hz, 24amp). However, another Sun
4/280 with two Hitachis and tape drive here has the 230V supply. The
February 3, 1988 price sheet only says that if you have *more* than two
drives you need the 230V, perhaps the addition of the tape drive bounces
the power requirements into that territory? From all I've heard, though,
you shouldn't need the 230V power supply in your case.
I wonder if you can bill Sun for headaches.... :-)

No and yes. Write yourself the simplest, stupidest program you can
imagine.
For each line of C code, extend it to 80 characters, blank filled. Write
a record. Repeat until done. Write an EOF.
If you want to be smarter and put more than one file on a tape, precede
each file with a record containing its filename, also 80 chars. At the end
of all files write another EOF so you have two in a row.
If the IBM insists on tape labels, label the tape on the mainframe and
skip the first record on UNIX by reading it.
All this assumes that you have raw interface to the magtape on the IBM.
If that fails, write a tape on the mainframe in standard format with known
contents, dissect it on the sun, and replace the contents of the mainframe
file with the Sun file. Then reread it on the mainframe.

Subject: fork/exec of some programs on Sun 3 with SunOS 4.0
The following program fails on a Sun3 with SunOS 4.0 but not SunOS 3.2.
It is not sensitive to the system on which the program is compiled and
linked (ie, not a dynamic loading problem).
#include <sys/time.h>
#include <sys/resource.h>
main()
{
struct rlimit rlp;
getrlimit(RLIMIT_STACK,&rlp);
rlp.rlim_cur -= 5*7*1024;
setrlimit(RLIMIT_STACK,&rlp);
system("ls");
}
gives this error when run:
% cc bug.c
1.1u 1.6s 0:10 28% 0+152k 28+21io 73pf+0w
% ./a.out
ld.so: map heap error (22) for /dev/zero
Just another reason to beware of SunOS 4.0, especially if you are
interested in using Common Lisp. Allegro CL uses `setrlimit' to set a
soft stack limit, thus allowing graceful handling of stack overflow.

Subject: fun with "limit"
csh fans, running 4.0, try this:
limit stacksize unlimited
now type ls. I get:
crt0: /usr/lib/ld.so mapping failure
Use limit to put your stacksize back to 2048k. If you are feeling
adventurous, try setting it to 2049k. Then when you try to ls you will
get
ld.so: map heap error (22) for /dev/zero
Maybe I am too uptight, but somehow I think that something is not right.
Shouldn't specifying "unlimited" give you the largest legal value that
actually works? Shouldn't setrlimit return an error if it can't tolerate
page-misaligned stack sizes? (maybe it does, I didn't check, but then
neither did csh!) Maybe it should truncate to valid offsets. Similarly
for ld.so: maybe the loader should be more clever about what it tries to
do. Anyway, I don't know enough about this newfangled 4.0 stuff to offer
a real solution. Am I correct in assuming there is a problem?

Subject: To qualify or not to qualify, that is the hostname
People seem to be having problems with using domain qualified hosts names
in various places, so I thought I would give an example of what can happen
if you don't.
We use Sun Unify/Simplify here for "distributed" data bases (data base
access over the network). Accessing the database is accomplished in part
by NFS and part by daemons fired up by inetd.
When we upgraded from SunOS 3.4 to SunOS 3.5, we switched over to using
domain qualified hostnames. Unfortunately, Sun Unify/Simplify broke. We
could access data remotely, but not update it, reconfigure, or reload. So
much for distributed databases.
We called the problem into Sun but after a few weeks we were convinced
that they weren't going to find an answer. On a wild guess, I changed the
mount entry in /etc/fstab to use the qualified hostname instead of an
alias. Lo and behold, things started working again.
The moral of the story is, there is a lot of broken software out there
that depends on exact matches or some kind of relation between what a host
sets its hostname to, what the official hostname in the host tables is,
and what hostname you ask for.

[[ Sad but true. Anyone out there tried to get remote lpr queueing to
work completely? Did you get "lprm" to work? Know why it's so hard?
"gethostname" has to return the *primary* host name and not a nic-name.
The name for the queued file is generated by the sending end using (in
part) "gethostname", but for an lprm the receiving end gets the
originating host name with a "gethostbyaddr" and tries to find a queue
file that matches exactly. --wnl ]]

Subject: Single User Default
One of our suns, when rebooted, always comes up in single user mode. To
get it to come up in multiuser mode you then have to hit ctl-d. When the
machine first starts to boot it prints: "b vmunix(0,0,0)" but does not
specify the -s option. I heard that there is a prom setting that will
bring the system up in single user mode even though the -s option is not
specified. Can anybody tell me what this flag is so I can change it? And
if there is something else going on entirely could somebody let me know
how to get the system to come up in multi-user mode without the ctl-d?

Subject: Mail to programs only works sometimes??
We are having strange problems here with mail to programs.
We have one alias 'paper' that sends the message to lpr. We have an
internal mailing list 'engine' that goes to a number of people and also
via recnews into a newsgroup. We are also on some outside mailing lists
with aliases that send the messages via recnews into newsgroups.
Now for the weird part: Sometimes this works and sometimes it does not.
The mail always gets to the people on the lists (or postmaster, if
postmaster is on the list), but will sometimes die when it gets to the
program. Sometimes everything works & sometimes everything does not. It
seems to depend on the phase of the moon. Also, I can not always stop
error messages from going back to the sender of the message. The error
message is always "Unknown user:" with no user given. There is no more
info in syslog either.
The switch between working & not working comes when we rebuild our alias
database (when we change it). We always rebuild both the YP database and
the 'normal' alias database (which is only on our master YP server).
There does not seem to be any rhyme or reason between it working or not
working.
Relevant lines in our /usr/lib/aliases file are:
# This sometimes works & sometimes does not.
paper: "|lpr -J'Paper copies of Mail'"
# This sometimes works, but usually does not.
isode-list: postmaster,cos-isode at cos.com
owner-isode-list: postmaster

We are using Sun OS 3.5 with Yellow Pages. "cos" (aka "cos.com") is our
YP Master server. There are 3 slave YP servers. There are a whole pile
of clients. The server (and its diskless clients) are the only things
running Sun OS 3.5, everything else is still running Sun OS 3.4.
We have asked Sun for help on this, but have gotten none yet (it seems
that all of their people are on vacation now).
If anyone has any clue as to what might be going on, please lets us know.
