Sun-Managers' Frequently Asked Questions
$Id: faq,v 3.48 1994/06/29 19:46:01 jdd Exp $
This is collection of common questions posted to the sun-managers mailing
list twice a month. It is intended to benefit Sun System Managers and
reduce traffic to the list by providing quick answers to common problems.
Keeping with the style of a similar FAQ for comp.windows.x, questions
marked with a '+' indicate questions new to this issue; those with
significant changes of content since the last issue are marked by '*'
The current FAQ maintainer is John DiMarco (jdd@cdf.toronto.edu). However,
all corrections/submissions should be sent to "sun-managers-faq@eecs.nwu.edu".
Note: I've reorganized the faq to add "subject" to each question,
for the benefit of list undigestifiers, and I've added (unofficial) sections
to make it easier to navigate the FAQ. -jdd, November 1993

1. The Sun-Manager's Mailing list
-----------------------------------------------------------------------------
Subject: 1.1) How do I read, join, post to, or remove myself from the
sun-managers mailing list?
To have your mailing address added to or removed from the mailing list,
send a request to "sun-managers-request@eecs.nwu.edu". The request should
contain simply one line which says either "add" or "remove". You can
specify the particular e-mail address to be added after the word "add".
If you wish to send a message to the sun-managers list, it is strongly
recommended that you first read the list's policy statement. This
statement is sent to the entire list on the first and 16th of every
month. It is also sent out to every new subscriber and is available via
anonymous FTP (see question 4) from "ra.mcs.anl.gov" in the file
"/sun-managers/policy". The policy statement includes instructions for
sending a message to the entire list.
The latest version of the FAQ list (this file) is also available on
"ra.mcs.anl.gov" in the file "/sun-managers/faq".
-----------------------------------------------------------------------------
Subject: 1.2) Are there any archives for the sun-managers list?
The site "aurora.latech.edu" archives every summary sent to
the list. Questions are not archived. This site provides access to its
archives via the WAIS and gopher protocols. It does NOT provide any
anonymous FTP access.
WAIS is the Wide Area Information Server, an experimental system that
provides for automatic search and retrieval of many types of electronic
information. Source for Unix WAIS clients can be obtained via anonymous
FTP from think.com in the directory "/wais". A WAIS "source" entry for
the sun-managers WAIS information server is available via anonymous FTP
from "ra.mcs.anl.gov" in the file "/sun-managers/sun-managers.src".
Gopher is a distributed document delivery service which allows even a
neophyte user access to a wide variety of information. If your system
already has a gopher client installed, you can access the sun-managers
gopher by simply typing "gopher aurora.latech.edu". Source for Unix
gopher clients can be obtained via anonymous FTP from
"boombox.micro.umn.edu" in the directory "/pub/gopher/Unix".
Even if you do not have full access to the Internet, you can still take
advantage of aurora.latech.edu archives and WAIS via the WAIS mail
server. While this is a primitive tool compared to interactive usage,
it does work. To get information on using the WAIS mail server, send a
message to waismail@quake.think.com with a body containing the single
word "help". If you wish to search the SUMMARY messages from
sun-managers, you can use the "sun-managers-summary.src" source.
-----------------------------------------------------------------------------
2. Getting Help Over the Net
-----------------------------------------------------------------------------
Subject: 2.1) How do I find out what patches are available from Sun?
If you have a software service agreement with Sun, you can use Sun's
"SunSolve ONLINE" service to obtain patches. Check your service
agreement for details.
Many anonymous ftp sites have partial collections of patches. The archie
service can be consulted.
WARNING: if you ftp patches from an ftp site, you are trusting whomever
put them there. To be absolutely safe, get your patches from a
trusted source.
Sun makes available certain security patches for anonymous ftp on
ftp.uu.net, in the directory /systems/sun/sun-dist. CERT and Sun often
publishes the checksums of security patches. You can use the UNIX "sum"
command to verify the identity of patches retrieved from ftp sites.
Rik Harris maintains a WAIS archive
(sun-fixes.src) of most available patch READMEs.
The Sun User Group (SUG) CD ROM also has a collection of Sun patches.
There is a special patch tape (U1) available from sun for Sun3's running
4.1.1 which fixes many of the bugs that were fixed for Sparcs in 4.1.2
and 4.1.3. Note that sun3's don't run anything later than 4.1.1.
-----------------------------------------------------------------------------
Subject: 2.2) What is "anonymous ftp" and how do I use it?
Anonymous ftp is a way to provide restricted file transfer access to a
host for the Internet community at large. You typically use ftp to
connect to a host and enter "anonymous" (possibly "ftp" or "guest") for
the user name and your "real" user name for the password. Do not type
your real password at any time, as it is common to log all anonymous
transactions and your password would be visible on the remote system.
When transferring files, make sure you have "binary" or "image" mode set
for transferring binary (non-ascii) files. This is true in the most
common cases, such as compressed files or tar archives. In some rare
cases, you might need "tenex" mode.
Read the manual page for 'ftp'.
-----------------------------------------------------------------------------
Subject: 2.3) How do I find anonymous ftp sites?
There are a number of well known ftp sites, such as "ftp.uu.net"
(137.39.1.2) and "gatekeeper.dec.com" (16.1.0.2). You usually find out
about these from newsgroups, mailing lists or word of mouth.
There is an internet service that allows you to search for ftp sites
that might have some file you're looking for. Telnet to one of the
following machines, using the login "archie":
archie.rutgers.edu 128.6.18.15 (Rutgers University)
archie.unl.edu 129.93.1.14 (University of Nebraska in Lincoln)
archie.sura.net 128.167.254.179 (SURAnet archie server)
archie.ans.net 147.225.1.2 (ANS archie server)
archie.au 139.130.4.6 (Australian server)
archie.funet.fi 128.214.6.100 (European server in Finland)
archie.doc.ic.ac.uk 146.169.11.3 (UK/England server)
archie.cs.huji.ac.il 132.65.6.15 (Israel server)
archie.wide.ad.jp 133.4.3.6 (Japanese server)
archie.luth.se 130.240.18.4 (Scandinavian server)
-----------------------------------------------------------------------------
Subject: 2.4) How do I get help upgrading to Solaris 2.x?
Start by reading the Solaris FAQ, maintained and posted periodically to
comp.unix.solaris by Casper Dik . It can be obtained
by anonymous ftp to ftp.fwi.uva.nl, in /pub/solaris.
-----------------------------------------------------------------------------
3. NIS, NIS+, DNS, and NFS
-----------------------------------------------------------------------------
Subject: 3.1) How do I set up NIS/YP to use DNS?
Under SunOS 4.1.x, there is a "#B=" at the top of /var/yp/Makefile,
uncomment and change this to "B=-b" and setup NIS in the usual
fashion. Under 4.0.x, edit the Makefile or apply the following
"diff":
*** Makefile.orig Wed Jan 10 13:22:11 1990
--- Makefile Wed Jan 10 13:22:01 1990
***************
*** 63 ****
! | $(MAKEDBM) - $(YPDBDIR)/$(DOM)/hosts.byname; \
--- 63 ----
! | $(MAKEDBM) -b - $(YPDBDIR)/$(DOM)/hosts.byname; \
***************
*** 66 ****
! | $(MAKEDBM) - $(YPDBDIR)/$(DOM)/hosts.byaddr; \
--- 66 ----
! | $(MAKEDBM) -b - $(YPDBDIR)/$(DOM)/hosts.byaddr; \
-----------------------------------------------------------------------------
Subject: 3.2) How do I use DNS instead of NIS for hostname resolution?
The "normal" behavior of a hostname lookup under NIS is to consult the
NIS hosts map and then DNS (if configured). You can change this so all
hostname lookups go directly to DNS. The SunOS shared library mechanism
allows you change the behavior of any command that is dynamically linked
to the shared library. In SunOS 4.1 and greater releases, there is an
optional package called "shlib custom" that contains a kit for
rebuilding shared libraries. You can select this in suninstall or load
it later. It will put the files in /usr/lib/shlib.etc. Note that
machines that come with pre-installed SunOS don't include this. It
contains both a "normal" and System V version of libc and some tools to
build shared libraries. The Sun-supplied README file gives some help,
but doesn't detail how to change the hostname lookup functions. The
complete procedure for this is spelled out in "bindon41.shar", which is
available for anonymous ftp from "ra.mcs.anl.gov" in "/pub" - it goes
one step further and replaces the Sun resolver routines with BIND 4.8.3
(or later) versions. Note that you can still use NIS for other things in
environment, such as passwd, group info, etc - the NIS hosts map is just
ignored. There are several important statically linked binaries that
will break if you replace the Sun routines. "/etc/mount" is probably
where you will first notice that it doesn't know about any host that is
not present in /etc/hosts. The same goes for "rcp". My solution was to
recompile mount and rcp with the new resolver routines, but you need
source code to do this. Sun apparently will give you a dynamically-
linked version of mount if you have software maintenance. You can
compile your own version of rcp from the Berkeley 4.3 source that is
available on various ftp site. Otherwise, you might just have to have
all hosts (and aliases) in /etc/hosts that you want to mount or use
Internet addresses (yuck). Another "feature" of a DNS-only environment
is that hostnames will sometimes be returned all in uppercase and these
will not match the lower-case entries you typically have in
/etc/exports, /etc/bootparams, etc. There are some patches to BIND 4.8.3
called "resolv+" that allow you to specify hostname lookups to
/etc/hosts only, DNS only or both.
bind 4.8.3 is on ucbarpa.berkeley.edu (128.32.130.11) in /4.3. resolv+ is
on osl.csc.ncsu.edu (152.1.58.11) in pub/SUNOS/resolv+-2.1.tar.Z
-----------------------------------------------------------------------------
Subject: 3.3) What does the "nres_gethostbyaddr !=" error mean?
This message is from "ypserv" and has been determined to be "harmless"
(bug #1039839). Get Sun patch 100482-02 or later which fixes this and
other bugs in NIS.
-----------------------------------------------------------------------------
Subject: 3.4) How come yppasswdd does not automatically update the yp maps?
There is a bug in 4.1 rpc.yppasswdd that causes it misinterpret the
command line arguments. A work-around is to add the "-nosingle" flag
(which is the default), this shifts the arguments over one, so "passwd"
is read instead of "-m".
For example:
rpc.yppasswdd /var/yp/passwd -nosingle -m passwd DIR=/var/yp
If you are running the C2 security package, you should apply patch
100201-04, as it fixes several problems with rpc.yppasswdd.
-----------------------------------------------------------------------------
Subject: 3.5) What does "NFS write error X" mean?
You can lookup the error codes in /usr/include/sys/errno.h. Two common
ones are 13, which is "permission denied" and 70 "stale file handle". 13
is probably coming from an incorrect /etc/exports entry. 70 will occur
when a fileserver goes down for some reason. You can usually get rid of
the error by unmounting and remounting the filesystem in question. Under
SunOS 4.1, you can run "showfhd" to translate the NFS "file handle"
given in the error message into a Unix pathname. Beware that showfhd
does a "find" on your server to get the filename. "man 2 intro" will
give you some more general information on what error codes could mean.
-----------------------------------------------------------------------------
Subject: 3.6) What does NFS getattr failed/RPC: Authentication error mean?
You are probably running a pre-4.0 version of NFS, or using another
vendor's system, and your username is in more than 8 groups. There is a
limit on the number of groups that could be represented in the rpc service
(called NGRPS). On pre-4.0 systems this was 8, now it is 16. Since many
vendors other than Sun are still running old versions of NFS, you might
see this error even if your SunOS is recent. Authentication errors are
also caused by having secure RPC enabled on the client but not on the
server, or by having a misconfigured secure RPC configuration for the user
name generating the errors. Beware of this problem when you are using the
automounter, as programs (such as Sendmail) may silently fail when when
they try to mount a directory and get this error.
-----------------------------------------------------------------------------
Subject: 3.7) How do I change NIS+ credentials for the root master server?
Use the passwd command on the root master server to change the root
password. But DO NOT follow this with a chkey -f to update the credentials
for the root master server, because this will disable the entire NIS+
domain. The only way to recover from this is to rebuild the domain from
scratch!
It is possible to change the credentials of the root master server, but
it is not easy. The procedure follows:
To change the keys for the root master server do as follows:
1. use these commands in this order:
nisupdkeys -CH master.server.name. groups dir.domain.name.
nisupdkeys -CH master.server.name. org dir.domain.name.
nisupdkeys -CH master.server.name. domain.name.
(This CLEARS the key for the HOST "master.server.name" in this
directory.)
2. Kill rpc.nisd and restart it at security level O then run this command:
nistbladm -R cname=master.server.name. cred.org dir.domain.name.
nisaddcred des
3. Shutdown and restart any replicas of org dir.domain.name. at run level O
nisping org dir.domain.name.
nisdupdkeys domain.name.
nisupddkeys org dir.domain.name.
nisupdkeys groupa dir.domain.name.
3. Kill and restart all rpc.nisd servers at level O to security level 2.
Note that changing a server's key affects all directory objects containing
the key.
Thanks to Rogerio Rocha and Sun INFODOC ID 1241 for this
information.

4. Window Systems
-----------------------------------------------------------------------------
Subject: 4.1) Can I run both OpenWindows and MIT X11?
The shared libraries for OpenWindows have different version numbers than
the MIT versions. MIT executables will try to use the OpenWindows
libraries and OpenWindows executables will complain about version
mismatches. You can toggle between the two environments by setting your
$path and LD_LIBRARY_PATH variables. Assuming you installed the MIT
executables in /usr/bin/X11, the MIT libraries in /usr/lib and the
OpenWindows libraries are in /usr/openwin/lib, set the following before
you start the windowing system:
MIT X11R4/R5 environment
set path = (/usr/bin/X11 $path)
setenv LD_LIBRARY_PATH /usr/lib
(Actually, for libraries in /usr/lib, /usr/5lib, or /usr/local/lib, the
LD_LIBRARY_PATH is not strictly necessary.)
Sun OpenWindows
set path = (/usr/openwin/bin /usr/openwin/demo $path)
setenv LD_LIBRARY_PATH /usr/openwin/lib
You can also run clients from one environment under a different server
on a one command at a time basis. This example runs a OpenWindows
client under the MIT server:
(setenv LD_LIBRARY_PATH /usr/openwin/lib; x_soundtool)
It is possible to run OpenWindows 3.0 and MIT X11 simultaneously
without having to toggle LD_LIBRARY_PATH as above, by putting the X11
libraries before the openwindows libraries in LD_LIBRARY_PATH, and the
X11 binaries before the openwindows binaries in PATH, as follows:
setenv LD_LIBRARY_PATH /usr/lib/X11:$OPENWINHOME/lib setenv path
(/usr/bin/X11 $OPENWINHOME/bin $path)
Setting LD_LIBRARY_PATH can be avoided altogether if the superuser links
all the openwin 3.0 and X11 libraries into /usr/local/lib as follows:
ln -s $OPENWINHOME/lib/lib*.s[oa]* /usr/local/lib ln -s
/usr/lib/X11/lib*.s[oa]* /usr/local/lib /etc/ldconfig
To use the X11 xdm with the openwin 3.0 Xnews server, modify the
Xservers file (eg. /usr/lib/X11/xdm/Xservers) to say something like the
following:
:0 local $OPENWINHOME/lib/xdm/StartOW -nosunview \ -fp
/usr/lib/X11/fonts/misc,$OPENWINHOME/lib/fonts,/usr/lib/X11/fonts/75dpi
Change the options or font path if necesary. Note that sun patch
100452-25 or later should be installed, to prevent the Xnews server from
consuming more and more memory as time passes.
(Thanks to Margarita Suarez for the last
three suggestions)
OpenWindows 3.x includes most of the MIT X11 libraries and header files.
Most MIT X11 Applications can be compiled and run under OpenWindows 3.0
without change.
The OpenWindows server has the ability to display PostScript that
several of the OpenWindows applications require to run. Sun's AnswerBook
is an example that requires PostScript. These clients will not run under
the MIT server. You can get a limited PostScript preview capability
under either server with GNU Ghostscript, a GNU "copyleft" package
available from various ftp sites. Two enhanced versions of Ghostscript
are also available, GSPreview and Ghostview, they both offer fancier
preview capabilities. These programs are currently available via
anonymous ftp:
Ghostscript and Ghostview are on prep.ai.mit.edu (18.71.0.38) in
/pub/gnu. GSPreview is on ftp.x.org (198.112.44.100) in /contrib
-----------------------------------------------------------------------------
Subject: 4.2) How do I run X11R5 on Solaris 2.x?
Note: in Solaris 2.3 and later, OpenWindows is X11R5-based, so you may
not necessarily need to run stock MIT X11R5. Note also that Mit X11R6
supports Solaris 2.x.
If you still wish to run Mit X11R5, start with a stock Mit X11R5
distribution, and apply all the outstanding X11R5 fixes. Grab
R5.SunOS5.patch.tar.Z from ftp.x.org:/contrib and apply it. Configure and
compile as per the patch instructions.
-----------------------------------------------------------------------------
5. Disks, Tapes and SCSI
-----------------------------------------------------------------------------
Subject: 5.1) What is the format.dat entry for drive X?
The answer can vary according to what OS you are running, the
architecture of your machine or the type of SCSI/SMD/IPI controller you
are using. Opinions also vary on how to format once you have all the
information you need. If you are buying a Sun supported drive, you will
likely find an entry for it in "/etc/format.dat". On third party
drives, you should inquire with the vendor you bought it from. If you
are on your own, contact the manufacturer, or try to get hold of the
manufacturer's OEM manual for your drive model. You might be able to
derive enough information from the manual to make up your own entry.
Some drive manufacturers run "bulletin boards" with drive information on
them:

A format.dat file containing entries submitted by various people is
available for anonymous ftp from ra.mcs.anl.gov in
/sun-managers/format.dat. It is currently maintained by John DiMarco
(jdd@cdf.toronto.edu). New entries (especially vendor-suggested ones)
are welcome; mail them to sun-managers-format@eecs.nwu.edu
Note: do not post a format.dat request to the list or to the
comp.sys.sun.admin newsgroup unless you have exhausted all these avenues.
If you have a SCSI disk on a sun4c, sun4m, sun4e, or sun4d running
SunOS 4.1.1 or later, grab John DiMarco's scsiinfo program from
ftp.cdf.toronto.edu:/pub/scsiinfo. It will query the disk directly,
and generate an appropriate format.dat entry
Tips for rolling your own format.dat:
- For SCSI disks, any combination of cylinders, heads, and sectors that
does not add up to more than the rated formatted capacity of the drive
will normally work. A grossly different geometry may result in some
slight performance degradation, but it should still work. The SCSI protocol
hides most of the drive details from the host, and hence the host need not
know much about the drive to format or use it.
-----------------------------------------------------------------------------
Subject: 5.2) Can I use a disk greater than 700meg?
Yes, Sun has 1.3 gigabyte drives and larger, or you can choose from a
variety of third party drives.
However, the SPARCstation SCSI drivers in SunOS 4.1.1 or earlier use
SCSI group 0 commands. This command set only has 21 bits of storage for
the block number. This means you can have 2^21-1 or 2097151 as the
largest block number understood by the SCSI driver. The fix is to use
SCSI group 1 commands, where you have 31 bits for block numbers. The
newer Sun SCSI drivers (SCSA) use group 1 commands, but require a patch
to work properly. The patch for a Sun4c running SunOS 4.1.1 is 100343-04
or later. This includes a new format.dat for the Sun 1.3 gig drive. The
patch will come with the drive if you order it from Sun or you can get
it from the Sun patch database mentioned in question 3. You can use 1.2
gigabyte drives with the current driver, but you "waste" several
megabytes (i.e. no big deal). The Fujitsu M2266SA, CDC/Imprimis/Seagate
Wren 7, HP 97549T and Micropolis 1598 are known to work.
This patch is only required for Sun4c's (Sparcstations) running SunOS
4.1.1 or earlier. Sun3's, Sun4m's (600 series, SS10), and Sun4's
(100,200,300,400 series) do not require it, and the patch is included in
SunOS 4.1.2 and later.
Note: Older Fujitsu M2266SA drives have a firmware bug in the use of the
on-drive read-ahead cache that causes random read errors. You can
disable the cache by removing the jumper on pins 5-6 on CN9. Fujitsu
recently has made new PROMs available that fix the cache problem. You
should be able to obtain these from your drive vendor at no cost. The
PROM is marked "81202" followed by a revision letter. Revision "C" and
earlier should be replaced by a "D" or later version.
Note: Older Wren 7's may not boot on IPX's, ELC's and later machines,
due to a bug in the Wren 7's firmware. Here is a patch to the NVRAM
which must be made from the monitor.
WARNING : It is important that you type this correctly. Check this
several times! Remember all the question marks, dashes and spaces
and yes, sstart should be with two "s"'s. Note: Syntax errors in
your NVRAMRC can make your machine unbootable. In Prom version
2.x, hitting L1-N after the selftest at bootup will reset the NVRAM.
If you have prom revision 2.0 to 2.5, inclusive:
(from monitor level)
> n
ok nvedit
0: true to fcode-debug?
1: probe-all install-console banner
2: cd /sd [ or whatever drive you want to boot from ]
3: patch 0 1 sstart
4: device-end
5: [ press c to exit nvedit at this point ]
ok nvstore
ok setenv use-nvramrc? true
ok reset
For prom revision 2.6 or greater, use:
(from monitor level)
> n
ok nvedit
0: probe-all install-console banner
1: cd /esp
2: ' 0 ' 1 ' timed-spin >body 7 /token * + token@ (patch
3: device-end
4: [ press c to exit nvedit at this point ]
ok nvstore
ok setenv use-nvramrc? true
ok reset
If you have a prom revision earlier than 2.0, or you don't wish
to use the nvramrc, a Wren VII can be made to boot by making
the "a" partition start at cylinder two, instead of cylinder zero.

Subject: 5.3) How do I move disks from xy451 to xy753/7053 controllers?
You have to reformat the drives for them to be recognized by the new
controller. Save the bad block list on drives while they are still on
the old controller and load this back on the disk when you are
formatting the disk on the new controller. The "dump" command in
"defect" menu of "format" will write out a defect list to a file, the
"load" command in the same menu will read the defect list from a file.
-----------------------------------------------------------------------------
Subject: 5.4) Why does my internal 105 megabyte hard disk stop working?
There is a problem in the Quantum 105S 3.5" disk with the drive
lubricant. It prevents the platter from rotating if it cools down
enough, which will happen if the drive is powered down. Before you call
Sun in for replacement, try removing the drive, holding it around waist
height, and give it a couple of quick twists in the plane of the disk
surface. This should loosen the lubricant. (Thanks to Dan Razzell
for this suggestion.) Tapping the disk lightly may
also work, but this is understandably risky.
-----------------------------------------------------------------------------
Subject: 5.5) Can I replace the 105 megabyte internal drive in a SS1/1+
with a higher capacity model?
The higher capacity drives sometimes create more heat and draw more
power than the 105S. The case cooling ability and power supply in the
SS-1 and SS-1+ is not adequate for drives significantly hotter than the
Quantum 105S. The Quantum 105S pulls 10W, so any disk much more than
this might be a problem.
Since the SS1/1+ supports two drives, if only one drive is installed,
it should be possible to relax this constraint somewhat.
-----------------------------------------------------------------------------
Subject: 5.6) How do I enable synchronous SCSI?
It depends on the type of SCSI controller and the SunOS release.
The SCSI device must be able to support it. Most modern SCSI drives
do, check the drive manual to see if there is a jumper or switch
to enable or disable it on the drive itself.
If you have a VME-based system with the Sun SCSI controller on a
separate card (a 4/470 for example), you are out of luck unless you go
with a third-party SCSI controller. The Sun VME SCSI "si" and "sc"
controllers are old products that were developed for the Sun3 line and
do not support many newer SCSI features. VME systems with the "sm"
controller on the cpu board, (such as the 4/370) are capable of sync
SCSI, along with desktop systems with the "esp" controller (SS-1, SS-1+,
SS2, etc). You can see what type of controller you have by watching the
boot process or running /etc/dmesg.
There were some problems with sync SCSI on the SS-1 that prompted Sun to
disable it by default in 4.0.3 and 4.1. You can enable it manually by
tweaking the kernel:
echo 'scsi_options?W 0x38' | adb -w /vmunix reboot system
or a better method:
uncomment the 'SCSI_OPTIONS_SYNC' line in /sys/scsi/conf/scsi_confdata.c
rebuild kernel reboot system
Under 4.1.x, sync SCSI is negotiated at boot time by checking each
device to see if it supports it. 4.1.x (except for 4.1.3) will print a
message if it is successful:
esp0: Target 3 now Synchronous at 4.0 mb/s max transmit rate
To turn on this message for SunOS 4.1.3, you can modify the kernel or
/sys/sun[4c|4m]/OBJ/esp.o using adb to set espdebug to 0x1 as above.
This can cause problems with some SCSI peripherals, however (eg. some
8mm drives).
Better still, grab John DiMarco (jdd@cdf.toronto.edu)'s "scsiinfo"
program which provides this information and more about SCSI peripherals
attached to ESP SCSI host adapters. scsiinfo is available for anonymous
ftp from ftp.cdf.toronto.edu in /pub/scsiinfo.
Note: SCSI cable length can affect drive performance, especially for
fast synchronous SCSI devices and controllers. Cable length should be
kept at a minimum.
-----------------------------------------------------------------------------
Subject: 5.7) Is it okay to disconnect or connect SCSI devices
while powered on?
On older machines (without onboard SCSI controllers), it is never a good
idea to do this. You risk blowing a fuse on the CPU board, or part of
the SCSI hardware. On newer machines (sparcstations and later), many
people have done this regularly without problems. Halt the machine
(sync;L1-A), remove or add the device, then continue. However, it is
possible to blow the SCSI termination power fuse on the motherboard. If
your machine hangs immediately on powerup unless the SCSI bus is
externally terminated, this fuse may need to be replaced. Caveat Emptor.
-----------------------------------------------------------------------------
Subject: 5.8) How do I configure a sun to use its local disk(s) for
swap but not for root?
It's necessary to configure the kernel to use a designated swap
partition. You can do this by replacing the line in the kernel config
file (/sys/`arch -k`/conf/KERNEL-NAME) that says
config vmunix swap generic
with
config vmunix root on type nfs swap on type spec
Replace '' with the name of the disk block device you want
to use, eg. 'sd0b'.
Thanks to Nick Sayer .
-----------------------------------------------------------------------------
Subject: 5.9) My HP DAT drive is running very slowly on my sun running
4.1.x. How do I fix this?
You'll need to add some configuration data for the HP DAT drive to your
Sun 4.1.x kernel as follows:
In /sys/scsi/targets/stdef.h, add the line:
#define ST_TYPE_HP1 0x2a /* HP C1533A DDS2 DAT drive */
In /sys/scsi/targets/st_conf.c, add the following:
/* added DAPM 5-feb-94
* HP C1533A DDS2 DAT tape drive */
{
"HP C1533A 4mm DDS DAT", 2, "HP",
ST_TYPE_HP1, 10240,
(ST_VARIABLE|ST_BSF|ST_BSR|ST_LONG_ERASE|ST_AUTODEN_OVERRIDE),
6000,6000,
{0x00, 0x00, 0x00, 0x00},
{0,0,0,0}
},
Recompile your kernel, and reboot with the new kernel.
Thanks to Dave Mitchell and
sjf@mod.dsto.gov.au (Stephen Fitzgerald).

6. Resource Management and Performance Tuning
-----------------------------------------------------------------------------
Subject: 6.1) How do I tell what caused my machine to crash?
The crash messages will usually be displayed on the console or kept
around after reboot long enough for you to run /etc/dmesg. Syslog can
sometimes record the crash message. If your system repeatedly crashes
with similar looking errors, try searching through the patch list on the
Sun patch database for a description that matches your machine. Read
chapter 22 of the SunOS 4.1 system administration manual on how to
gather more information for reporting a crash and making crash dumps.
To enable a crash dump, uncomment the "savecore" lines in /etc/rc.local.
To report a crash dump, you need a symbolic traceback for it
to be useful to the person looking at it. Type the following:
cd /var/crash/`hostname`
echo '$c' | adb -k vmunix.0 vmcore.0
-----------------------------------------------------------------------------
Subject: 6.2) What can I do if my machine slows to a crawl or just hangs?
Try running "ps" to look for large numbers of the duplicate programs or
processes with a huge size field. Some system daemons occasionally can
get into a state where they fork repeatedly and eventually swamp the
system. Killing off the child processes doesn't do any good, so you have
to find the "master" process. It will usually have the lowest pid.
Another useful approach is to run vmstat to pin down what resource(s)
your machine is running out of. You can tell vmstat to give ongoing
reports by specifying a report interval as its first argument.
The programs "top" and "sps" are good for finding processes that are
loading your system. They can be found a most anonymous ftp sites (try
gatekeeper.dec.com:pub/sysadm). "Top" will give you the processes that
are consuming the most cpu time. "Sps" is a better version of "ps" that
runs much faster and displays processes in an intuitive manner.
Sometimes you run out of memory and you won't be able to run enough
commands to even find out what is wrong. You will get messages of the
type "out of memory" or "no more processes". Note that "out of memory"
refers to virtual memory, not physical memory. On a 4.x system (or
earlier), the size of a machine's virtual memory is equal to the amount
of swap space it has. On a 5.x system, it is generally equal to the sum
of the swap space and the amount of physical memory (less a roughly
constant amount for the kernel) on the machine.
You can sync the disks to minimize filesystem corruption if you have to
crash the system:
Use the L1-A sequence to crash the system. If you are on an older system,
type "g0" and you will get the message "panic: ... syncing file systems".
When you see the word "done", hit L1-A again and reboot. On systems
with the "new" prom, type "n" to get into the new command mode and type
"sync".
Sometimes a system hang or similar slowdown can be caused by an OS bug.
In particular, patch 100330-03 or later fixes some OS bugs in SunOS
4.1.1 that can cause system hangs in certain circumstances.
-----------------------------------------------------------------------------
Subject: 6.3) How do I find out how much physical memory a machine has?
For machines running SunOS 5.x, use /usr/sbin/prtconf. If the machine is
running an earlier version of SunOS, one of the following techniques can
be used:
Try "/etc/dmesg | grep mem". This takes advantage of the fact that the
kernel writes the amount of physical memory on the machine to the
console on reboot. /etc/dmesg reports the most recent messages written
to the console.
If many messages have been written to the console since the machine was
rebooted, the message reporting the amount of physical memory may no
longer be in the buffer. If you save console messages to
/var/adm/messages (usually true by default), you can try "grep mem
/var/adm/messages*". If the message is no longer in the buffer, it still
may be in the messages log file.
The banner message on reboot (or type "banner" in the monitor on machines
with Openboot proms) will usually report the amount of physical memory.
Alternatively, you can poke around in /dev/mem and /vmunix (or
equivalent), or open up the case and count SIMMS and/or memory boards.
To make poking around in /dev/mem and /vmunix a little easier, a little
C program that uses /dev/mem and /vmunix to report the amount of
physical memory is available for anonymous ftp on "ra.mcs.anl.gov" in
the file "/sun-managers/mem.shar". Or even better, grab Michael Cooper
(mcooper@usc.edu)'s "sysinfo" program, which provides all sorts of
information about a given system, including how much physical memory it
has. sysinfo is available for anonymous ftp from usc.edu in
/pub/sysinfo.
-----------------------------------------------------------------------------
Subject: 6.4) How do I find out what my machine's memory is being used for?
How can I tell if I need more memory?
To discover how much virtual memory (i.e. swap) is free, for SunOS 3.x
and 4.x, run "pstat -s", and for SunOS 5.x, run "swap -s" or "vmstat".
If you're using tmpfs for /tmp, "df /tmp" will also work.
Discovering how physical memory is being used can be more difficult,
however. For SunOS 3.x, vmstat will tell you how much physical memory is
free. This doesn't work under SunOS 4.x and 5.x, since the kernel's
memory subsystem is completely different. Memory pages that are not
being used by processes are used as a sort of extended cache, storing
pages of memory-mapped files for possible later use. The kernel keeps
only a small set of pages free for short-term use, and frees up more on
demand. Hence the free memory reported by vmstat is not an accurate
reflection, for example, of the amount of memory available for user
processes.
For SunOS 4.x, a small C program is available which indicates how the
system has allocated memory pages. Its output looks like the following:
vmpage: all results in decimal pages
physmem 16298, startup 839, maxmem 15459, pageable 14853
scanned 15469, locked 4, kept 612, cached 8124, free 6729
vmpage is availabe for anonymous ftp from ra.mcs.anl.gov as
/sun-managers/vmpage.tar.Z
An easy way to determine whether or not your machine needs more memory
is to run vmstat and examine the po (page out) column and the sr (scan
rate) column. If these columns consistently show large numbers, this
suggests that your machine does not have enough memory to support its
current workload, and frequently needs to write pages belonging to
active processes to disk in order to free up enough memory to run the
current job.
-----------------------------------------------------------------------------
7. Anonymous FTP Service
-----------------------------------------------------------------------------
Subject: 7.1) How do I set up anonymous ftp on my machine?
Read the man page ftpd(8) in the SunOS 4.x documentation, as the
procedure differs from vanilla BSD and most examples in system
administration books. The "ls" binary is dynamically linked, requiring
you to duplicate ld.so, libc.so.* and /dev/zero in the ftp area. The
permissions and ownership of the files within the ftp area are critical
to having a secure configuration.
-----------------------------------------------------------------------------
Subject: 7.2) Where can I get a version of ftp that does logging?
These are 4 versions that have enhanced logging or can be modified
to enable logging:
wuarchive.wustl.edu (128.252.135.4) /packages/ftpd.wuarchive.shar
isy.liu.se (130.236.1.3) /pub/ftpd.tar.Z
ftp.adelaide.edu.au (129.127.40.3) /pub/4.3/ftpd-sirius.tar.Z
ftp.cs.widener.edu (147.31.254.132) /pub/src/widener/ftpd-wid.tar.Z
The stock Sun ftpd will log some information if you add the "-l"
flag in /etc/inetd.conf:
ftp stream tcp nowait root /usr/etc/in.ftpd in.ftpd -l
Also enable syslogd by adding:
daemon.info /var/adm/syslog
to "/etc/syslog.conf".
-----------------------------------------------------------------------------
8. Consoles, Keyboards and Key Remapping
-----------------------------------------------------------------------------
Subject: 8.1) How do I make the numeric keypad on a type 5 keyboard
work with xterm?
You need to patch the /usr/lib/X11/app-defaults/XTerm and
$OPENWINHOME/lib/app-defaults/XTerm files as described in sun patch
100713-01 or later.
-----------------------------------------------------------------------------
Subject: 8.2) How do I swap the CAPS LOCK and CONTROL keys on a
type 5 keyboard under Openwindows 3.0?
Don't do it with xmodmap, since that won't change the locking behaviour
of CAPS LOCK. Edit $OPENWINHOME/etc/keytables/US5.kt. There are two
places where keys 119 (CapsLock) and 76 (Control) should be swapped: the
MODMAP section and the KEYSYMMAP section. The latter is most important,
because that's where the "Pseudo-Lock" function (which controls the
locking behaviour of the key) is defined.
Thanks to Margarita Suarez for the
answers to this and the previous question.
-----------------------------------------------------------------------------
Subject: 8.3) How do I use the keyboard and display when the console
is on ttya?
/dev/mouse and /dev/kbd are disabled when you use ttya or ttyb for
a console. You need to make new ones, which you can use with xdm
to support the keyboard and display while the console is on the
serial port. Here's how:
1. Make new special files corresponding to the "raw" kbd and mouse:
mknod /dev/zs2 c 12 2 # The keyboard
mknod /dev/zs3 c 12 3 # The mouse
These are just serial ports and will need some "special treatment"
in order to behave as /dev/kbd and /dev/mouse.
2. Shutdown your machine and tell the monitor to use ttya (or ttyb)
setenv input-device ttya
setenv output-device ttya
(or use the eeprom command to do this)
3. Reset and reboot. /dev/fb, /dev/kbd and /dev/mouse are now useless.
/dev/bwtwo0 (or whatever your framebuffer device is) works as a
substitute for /dev/fb. Also /dev/ttya (or ttyb) is useless - if you
have an entry in ttytab for it, comment it out.
4. Modify the StartOW file in the xdm directory
($OPENWINHOME/lib/xdm) and add the following lines:
KEYBOARD=/dev/zs2
MOUSE=/dev/zs3
FRAMEBUFFER=/dev/bwtwo0 # or whatever your framebuffer is
export MOUSE KEYBOARD FRAMEBUFFER
This file is only used by xdm to control the local display (see
the Xservers file). So setting these variables will not affect
xdm running on any other foreign display (i.e. xterminal).
5. Set the OPENWINHOME environment variable, then start xdm with the
config option, for example in /etc/rc:
OPENWINHOME=/usr/openwin; export OPENWINHOME
if [ -f $OPENWINHOME/lib/xdm/xdm-config ]; then
$OPENWINHOME/bin/xdm -config $OPENWINHOME/lib/xdm/xdm-config &
echo "Starting XDM..."
fi
Thanks to "John D. Barlow" and
David Moline for these instructions.
-----------------------------------------------------------------------------
9. Sun models and OS Versions
-----------------------------------------------------------------------------
Subject: 9.1) Which Sun models run which versions of SunOS?
Will SunOS 4.x work on a SPARCclassic or LX?
On a multiprocessor SS10?
Sun-supported configurations:
Sun2: SunOS 4.0.3 or earlier.
Sun386i: SunOS 4.0, 4.0.1, 4.0.2 only.
Sun3: SunOS 4.1.1 or earlier.
4/100, 4/200 series: SunOS 3.2, SunOS 4.0 or later.
4/300 series: SunOS 4.0.3 or later.
4/400 series: SunOS 4.1PSR_A or later.
600 models 120, 140: SunOS 4.1.2 or later.
600 model 41, 51: SunOS 4.1.3 or later.
600 models 412, 512: SunOS 5.1 or later.
600 model 514: SunOS 5.3 or later.
SPARCstation 1, 1+, SLC, IPC: SunOS 4.0.3 or later.
SPARCstation 2, ELC, IPX: SunOS 4.1.1 or later.
SPARCstation 10 models 20, 30, 40, 41, 51: SunOS 4.1.3 or later.
SPARCstation 10 models 412, 512: SunOS 5.1 or later.
SPARCstation 10 model 402: SunOS 5.2 or later.
SPARCstation 10 model 514: SunOS 5.3 or later.
SPARCstation 20 models 50, 51, 61: SunOS 4.1.3 or later.
SPARCstation 20 models 512, 514, 612: SunOS 5.3 or later.
SPARCclassic, SPARCstation LX: SunOS 4.1.3C or later.
SPARCstation Voyager, SPARCstation 5: Solaris 1.1.1B or Solaris 2.3
edition II or later.
Sun sells an unbundled version of 4.1.3 for the Classic and LX,
called Solaris 1.1 version C. Note that Classic and LX systems do not
come with a right-to-use licence for 4.1.3; this needs to be purchased
separately from sun. Similarly, Voyager and SS5 systems do not come with
a right-to-use licence for Solaris 1.1.1B; this needs to be purchased
separately.
SunOS 4.1.3 has been reported to run on the SPARCstation 10 model
412/512 and the 600 model 412/512, but this configuration is not
supported by Sun. Anyone who tries this is on their own. The
(unofficial) word from inside Sun about whether or not it actually works
is as follows:
Little testing of the SuperSPARC MP configurations under 4.1.3
have been done by Sun. What little was done showed that under
heavy loads the system was prone to crash (What it really did was
hang, so badly that even an L1-A would not work).
...
We suspect, but do not know, that as the SuperSPARC chips get
faster that the problems will manifest themselves more quickly.
Caveat Emptor.
SunOS 5.0 runs only on SS1,1+,2,SLC,IPC,ELC,IPX.
SunOS 5.1 and later runs on all Sun4s and SPARCstations, but the FPU's on
the 4/100 and 4/200 series machines are disabled.
Not all peripherals supported under SunOS 4.x are supported under SunOS
5.x. Check with Sun or the peripheral manufacturer.
Explanatory note:
In general, Solaris = SunOS + Open Windows.
Solaris 1.0 = SunOS 4.1.1 + Open Windows 2.0
Solaris 1.0.1 = SunOS 4.1.2 + Open Windows 2.0
Solaris 1.1 = SunOS 4.1.3 + Open Windows 3.0
Solaris 1.1.1 = SunOS 4.1.3_U1 + Open Windows 3.0_U1
Solaris 2.0 = SunOS 5.0 + Open Windows 3.0.1
Solaris 2.1 = SunOS 5.1 + Open Windows 3.1
Solaris 2.2 = SunOS 5.2 + Open Windows 3.2
Solaris 2.3 = SunOS 5.3 + Open Windows 3.3
-----------------------------------------------------------------------------
Subject: 9.2) How can my program tell what model Sun it is running on?
On older suns, the model type is encoded in the hostid. For
suns with the "Openboot" prom (All sparcstations and the 600 series),
/usr/etc/devinfo (SunOS 4.x) or /usr/sbin/prtconf (Solaris 2.x) will
reveal the model type.
"Suntype", written by John DiMarco (jdd@cdf.toronto.edu) is a shell
script which does the appropriate thing on all suns. It is available
for anonymous ftp from ra.mcs.anl.gov in /sun-managers/suntype
-----------------------------------------------------------------------------
Subject: 9.3) What sorts of MBUS CPU modules are there? How can I tell
what module is in what model of SS10/SS600?
Two sun models, the SS10 and the SparcServer 600 series, support Sun's
MBUS. Both the SS10 and the 600 series have two MBUS slots. Both modules
must be of the same type.
Module #CPUS Processor Clck Ex.Cache Comments
------- ------ ---------- ---- -------- ----------------------------------
RT601 2 RT601/CY601 40 64k Rev 8 required for SunOS 5.x
SM20 1 SuperSPARC 33 -
SM21 1 SuperSPARC 33 1M Not sold by Sun
SM30 1 SuperSPARC 36 -
SM40 1 SuperSPARC 40 -
SM41 1 SuperSPARC 40 1M
SM50 1 SuperSPARC 50 - SS20 only
SM51 1 SuperSPARC 50 1M

RTQ66dual 2 HyperSPARC 66 256k Not available from sun
SM512(?) 2 SuperSPARC 50 1M Double-width: 1 SBUS + 1 MBUS slot
The particular module(s) in use can be determined from the model number
in a straightforward way. If the module number is of the form "AB" (eg. 51),
"A" indicates the clock rate of the module being used, and "B" is a flag
indicating whether or not there is an external cache. If the module number
is 120 (140), the system contains one (two) RT601 module(s). Finally,
if the module number is of the form "ABC" (eg. 514), "A" indicates the
processor clock rate, "B" is a flag indicating whether or not there is
an external cache, and "C" indicates the number of processors in the system.
For example, a model "514" has four 50 MHz SuperSPARC processors, hence
contains two of the double-width SM512 modules.
-----------------------------------------------------------------------------
10. Miscellaneous Software
-----------------------------------------------------------------------------
Subject: 10.1) My rdump is failing with a "Protocol botched" message.
What do I do?
The problem produces output like the following:
DUMP: Date of this level 0 dump: Wed Jan 6 08:50:01 1993
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rsd0a (/) to /dev/nrst8 on host foo
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 8232 blocks (4.02MB) on 0.00 tape(s).
DUMP: Protocol to remote tape server botched (in rmtgets).
rdump: Lost connection to remote host.
DUMP: Bad return code from dump: 1
This occurs when something in .cshrc on the remote machine prints
something to stdout or stderr (eg. stty, echo). The rdump command
doesn't expect this, and chokes. Other commands which use the rsh
protocol (eg. rdist, rtar) may also be affected.
The way to get around this is to add the following line near the
beginning of .cshrc, before any command that might send something
to stdout or stderr:
if ( ! $?prompt ) exit
This causes .cshrc to exit when prompt isn't set, which distinguishes
between remote commands (eg. rdump, rsh) where these variables are not
set, and interactive sessions (eg. rlogin) where they are.
-----------------------------------------------------------------------------
Subject: 10.2) My rpc.etherd keeps reporting "bad lnth" messages. Why?
There is a bug in the ethernet driver for SunOS 4.x which causes short
requests (eg arp, ICMP, loopback) sent by the host to be forwarded to
rpc.etherd with incorrect padding. The message is harmless, and can be
safely ignored.

11. Miscellaneous Hardware

Subject: 11.1) How come my mouse occasionally doesn't work?
You may have one of the bad mice that came with early SS-1 shipments.
The LED on the underside of the mouse can fail. Request a replacement
from Sun.

Subject: 11.2) How can I turn my Sun3 into an X-Terminal?
You can simply replace the getty command for the console in /etc/ttytab
with a command that starts up an X server. Alternatively, you can use
Seth Robertson's Xkernel package. This is available via anonymous ftp
from sol.ctr.columbia.edu (128.59.64.40) in /Xkernel. The package
describes how to configure a minimal kernel that runs the X server and
offloads all the clients onto another, hopefully more powerful host on
the network. This is attractive to some sites that have a large
investment in sun3 platforms, as moving most of the processing off the
sun3 cpu makes it tolerable to use. The price of a used 3/50 is
competitive with low-end X Terminals and you get a 19" monitor with an
optical mouse. Some disadvantages are that 4.1.1 is supposed to be the
last SunOS release on the sun3, and maintenance costs may be higher for
sun3 hardware.

Subject: 11.3) How do I do hardware flow control on an ALM-2?
Hardware flow control is only supported on the first four ports
(0-3) of the ALM-2. The other ports do not support hardware flow
control. So just use one of ports 0-3.

Subject: 11.4) + Is there a third-party source for SPARCprinter consumables?
Yes, there is. The SPARCprinter is OEM'ed by Xerox, and uses the same
consumables as the Xerox 4030 laserprinter. The appropriate part
numbers are:
Toner cartridge: 365-1124-01 Sun
6R281 Xerox
Drum cartridge: 365-1125-01 Sun
13R32 Xerox
Fuser Lubricant/oil: 370-1371-01 Sun
94E95090 Xerox
Fuser wick: 811-1687 Sun (Sun Express)
Xerox may be contacted in the US by calling 800-822-2200, or their tech
support number: 800-822-2979.

12. Networking
-----------------------------------------------------------------------------
Subject: 12.1) Why do both my interfaces have the same ethernet address?
The Ethernet version 2.0 specification (November 1982) states:
The physical address of each station is set by network
management to a unique value associated with the station,
and distinct from the address of any other station on any
Ethernet. The setting of the station's physical address
by network management allows multiple multiple data link
controllers connected to a single station to respond to
the same physical address.
This doesn't normally constitute a problem because each interface will
typically be on a different subnet. If, for some reason, different
ethernet addresses are required on different interfaces (for example, to
attach two interfaces to the same subnet), a new one may be assigned
using the ifconfig command.
