1. The Sun-Manager's Mailing list
_________________________________________________________________
1.1) How do I read, join, post to, or remove myself from the
sunmanagers mailing list?
Point your web browser to http://www.sunmanagers.org
Persons without web access should send a mail message to
"sunmanagers-request@sunmanagers.org" containing the single word
"help".
Messages can be posted to the list by mailing them to the address
"sunmanagers@sunmanagers.org". Do not do this until you have read the
charter/policy (question 1.2) and the "how to post" document at
http://www.sunmanagers.org.
The policy and the "how to post" document is sent to the entire list
twice a month. It is also sent out to every new subscriber and is
available at http://www.sunmanagers.org.
The latest version of the FAQ (this file) is available at
http://www.sunmanagers.org
_________________________________________________________________
1.2) What is the Sun-Manager's Charter? What are the rules?
1: This list is NOT moderated! Every message that is sent to the list
will be passed on to every member of the list.
2: Requests to have addresses added or removed from the list should
NOT be sent to the entire list. Instead, addresses should be added or
removed via the web page at http://www.sunmanagers.org Similarly, test
messages of any sort should not be sent to the list.
3: This list is intended to be a quick-turnaround trouble shooting aid
for those who administer and manage Sun systems. Its primary purpose
is to provide the Sun manager with a quick source of information for
system management problems that are of a time-critical nature.
4: All responses are to be mailed back to the questioner and are NOT
to be sent to the entire list. Any response to a list message sent to
the list, rather than to the person asking the question, will be
deleted without notice. The person who originally asked the question
has the responsibility of summarizing the answers and sending the
entire summary back to the list. When a summary is sent back to the
list, the word "SUMMARY" should be the first word of the "Subject"
line.
5: Discussions on ANY topic are not allowed and will not be tolerated.
If you want to discuss something, take it to the appropriate Sun
newsgroup.
6: If it is not specifically related to Sun system management, then it
does NOT belong on this list. Requests for vendor recommendations are
tolerated, provided that the hardware in question is something that
system managers normally purchase.
7: Commercial Advertising of any sort on the list is strictly
prohibited.
8: Postings about employment, either employment sought or offered, are
not permitted on this list. Please use a more appropriate forum, e.g.
one of the newsgroups in the misc.jobs USENET hierarchy.
9: Requests for software (free or otherwise) should be limited to
software that is directly related to Sun SYSTEM MANAGEMENT ONLY.
10: Read the appropriate manuals BEFORE posting, including the "Read
This First" documents. Oftentimes the manuals contain answers for
common problems.
11: When including a traceback from a system panic, make sure that it
is a symbolic traceback. Numeric tracebacks (the ones included as part
of the panic message) are not helpful; don't bother sending them to
the list.
12: A posting to sunmanagers is not a general invitation to email the
poster -- if you wish to send email to a sunmanagers poster, the email
you send should be related to the posting, else it will be unsolicited
email and may be treated like any other unsolicited email (e.g. spam).
Sunmanagers is not to be used to collect email addresses of people who
manage Sun systems. Those who do this not only violate the list's
policy, but risk seriously offending the very people they are
attempting to reach.
13: PLEASE PLEASE PLEASE...Think before you send a message! Ask
yourself "is this really appropriate?" There are enough other
newsgroups and mailing lists around to cover the marginal topics.
Perhaps there is another forum that is more appropriate? Check the
list of Sun specific newsgroups included in the FAQ. Perhaps your
message would be more appropriate there? Remember that Sunmanagers is
very public: we have thousands of subscribers, all postings are
archived for posterity on various archive sites, and these sites are
in turn searchable via various web engines. Submitting a posting is
irreversible -- once it goes out, it cannot be taken back!
Failure to adhere to these guidelines may result in severe
chastisement by the list participants. Not only will you succeed in
looking like a careless fool, and in making Sun Systems Managers all
over the world annoyed at your incompetence, you may end up damaging
your professional reputation.
_________________________________________________________________
1.3) Are there any public archives for the sunmanagers list?
Sunmanagers' official archive is accessible at
http://www.sunmanagers.org All postings are automatically archived. It
is our policy not to accommodate requests to modify the archives, so
if you are uncomfortable with your submissions in their entirety being
public, do not submit them.
Also, various members also keep their own archives on their own
initiative. Some of these are public. Here are some we know about:
http://aa11.cjb.net/sun_managers/index.htm
Hank Leininger <hlein at progressive-comp dot com> maintains a
searchable archive site of messages (both questions and summaries) in
Florida. It can be accessed at:
http://marc.theaimsgroup.com/?l=sun-managers
Dataman Benelux in the Netherlands hosts a "fuzzy" full-text index of
the Sun Managers mailing list at:
http://www.dataman.nl/cgi-bin/sunmanagers
Manfred Liebchen <liebchen at rrz dot Uni-Koeln dot DE> maintains an
archive site in Germany. It can be accessed at:
http://www.uni-koeln.de/RRZK/Abt-Systeme/sun/infos/SUN-MANAGERS/sunman
.html
Older summaries (up to mid-1999) are available at
http://www.latech.edu/sunman.html
_________________________________________________________________
1.4) What should I keep in mind when posting to sunmanagers?
* VERY IMPORTANT! Before you post, read the sunmanager's list
policy, which is available at http://www.sunmanagers.org
* Sun Managers is a huge unmoderated mailing list. Every message you
send will be passed on to every member of the list. This means you
have access to a much larger audience when you need help, but it
also means you can embarrass yourself in front of a huge number of
people, most of them professionals in your field, including
colleagues, peers, and possible future employers. Further, your
posting will be archived in various places, some public, some
private -- we have no way of knowing all the archive locations.
Some of these archives, including the official one at
http://www.sunmanagers.org, are web-searchable. It is our policy
not to accommodate requests to remove or modify postings as
archived on http://www.sunmanagers.org. Once you submit your
message, it will be irretrievably accessible to a large number of
people. There is no "taking it back".
* Sun Managers is completely voluntary. Nobody is required to help
you. We are all cooperating by sharing our knowledge. Accept with
grace whatever responses you get, and don't hound people if they
are helpful or they won't be the next time.
* Sun Managers is not the list to use when you run out of other
places to post. Job postings, PC questions, X questions all have
their own lists and newsgroups. Use only the appropriate list or
newsgroup for such things, not Sun Managers. Inappropriate
postings will only make people annoyed at you.
* The more information you give about a problem, the easier it is
for others to help you. This doesn't mean you should uuencode the
kernel and post it, but you should include your OS version, your
hardware, and all relevant symptoms of your problem. Unless the
request is of a general nature, the output of "uname -a" is almost
certainly helpful.
* When making a summary, please summarize as much as possible all
the answers you received, even the ones you didn't decide to
follow: if you receive several different suggestions, and decided
on one, remember that somebody else reading the summary may not
find the suggestion you followed to be the best one in his or her
situation, and may benefit from one of the suggestions you didn't
choose.
* Be generous. If you have the information requested (especially if
it is obscure) then please respond. You may be the person
requesting help next time.
_________________________________________________________________
1.5) What other forums are there for Suns?
Other forums that relate to Suns: USENET Newsgroups (accessible via
"rn", "readnews", "nn", netscape, etc.): There is an entire USENET

_________________________________________________________________
1.6) Where are the answers to questions about old Suns and old
versions of Solaris?
Those questions and answers used to be in this FAQ, but since they're
no longer frequently asked, they've been moved elsewhere.
The FAQ as of late 2005 contained information about pre-UltraSPARC
suns and versions of Solaris before Solaris 8, and is available at
ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq-2005.
The FAQ as of late 2000 contained information about pre-SPARC suns,
early SPARCstations, and SunOS 4.x, and is available at
ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq-2000.
_________________________________________________________________
1.7) What fields can I use to filter Sun Managers email?

2. Getting Help Over the Net
_________________________________________________________________
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.
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.
Rik Harris <rik.harris at vifp dot monash dot edu dot au> 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.
_________________________________________________________________
2.2) * How do I get help migrating to Solaris?
Start by reading the Solaris FAQ, maintained and posted periodically
to comp.unix.solaris by Casper Dik <Casper dot Dik at Holland dot Sun
dot COM>. It can be obtained at
http://www.science.uva.nl/pub/solaris/solaris2 Then go to the Solaris
Security FAQ, maintained by John Pancharian and hosted by IT World at
http://www.itworld.com/Comp/2377/security-faq/
Sun has a programme for developers/companies to migrate to Solaris.
It's documented at http://advantage.sun.com/partners/10moves/.
_________________________________________________________________
2.3) How do I access Sun's documentation over the net?
Sun has a web site devoted to documentation, at http://docs.sun.com
_________________________________________________________________
2.4) To which web sites can I go for help?
This is not a complete list, but:
First, see the answer to question 2.2.
Sun's documentation is available at http://docs.sun.com You can search
the Sun newsgroups at http://www.dejanews.com Sun-Managers Archives
are described in the answer to question 1.3 above.
Some sites suggested by Jeffrey Meltzer <meltzer at villagenet dot
com> are:
* SolarisGuide - http://www.solarisguide.com
* SunHelp - http://www.sunhelp.org
* SolarisCentral - http://www.solariscentral.org
* SunGuru - http://www.sunguru.com
* SunFreeware - http://www.sunfreeware.com
TechTarget has a search engine at
http://searchenterpriselinux.techtarget.com that also covers Solaris.
Eric De Mund <ead at ixian dot com> suggests the BigAdmin site run by
Sun, at http://www.sun.com/bigadmin
Alan Pae <alanpae at ilkda dot com> suggests Sun Country, at
http://www.ilkda.com
_________________________________________________________________
3. Network Directory and Files Services
_________________________________________________________________
3.1) How do I use DNS for hostname resolution?
In Solaris 2.x, this is easy: simply edit /etc/nsswitch.conf and put
"dns" before (or instead of) nis or nisplus on the line that begins
with "hosts:". For example, to look up hostnames first in the host
file and then in the DNS, use "hosts: files dns"
_________________________________________________________________
3.2) How do I change NIS+ credentials for the root master server?
If an NIS+ system is functioning correctly and only the root password
and root private keys for the system need to be changed, follow these
CSI 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.
_________________________________________________________________
5.4) How do I configure my sun to use Exabyte 4mm DAT tape drives?
Add the following to /kernel/drv/st.conf:
tape-config-list =
"EXABYTE EXB-4200", "Exabyte 4mm EXB-4200", "EXBT-4200",
"EXABYTE EXB-4200c", "Exabyte 4mm EXB-4200c", "EXBT-4200c"
EXBT-4200 = 1,0x34,1024,0x0029,4,0x63,0,0,0,3;
EXBT-4200c = 1,0x34,1024,0x0029,4,0x63,0,0x13,0,3;
Exabyte also recommends that their 4mm tape drives have firmware
revision levels of at least the following when used on suns:
* EXB-4200 No restriction, but revision 148 or higher is recommended
* EXB-4200c Level 149 minimum (mode select for compression)
Thanks to Dave Hightower <hightowr at afwc dot af dot mil>.
_________________________________________________________________
5.5) Why is tagged queueing a problem on my third-party disk?
Tagged Command Queueing (TCQ) is an optional part of the SCSI-2
specification. It permits a drive to accept multiple I/O requests for
execution later. These requests are "tagged" by a reusable id so that
the drive and the OS can keep track of them. The drive can reorder
these requests to optimize seeks. For more details, see the SCSI-2
specifications. A draft version is available at
ftp://ftp.cs.toronto.edu/pub/jdd/scsi-doc/scsi2.10b.gz
SunOS 4.x and earlier never uses tagged queueing. However, Solaris 2.x
will make use of tagged queuing if the drive claims to support it.
Unfortunately, some drive manufacturers have found it hard to design
their drives to do tagged queueing properly, and this particular area
has been a common source of bugs in drive firmware.
If it is not possible to turn off tagged queueing in the drive that is
causing the problem, Solaris 2.x can be told not to use tagged
queueing at all, by putting the following line in /etc/system:
set scsi_options & ~0x80
The "scsi_options" kernel variable contains a number of bit flags
which are defined in /usr/include/sys/scsi/conf/autoconf.h. 0x80
corresponds to tagged queueing.
However, this turns off tagged queueing for the entire machine, not
just the problematic drive. Because tagged queueing can provide a
significant performance enhancement for busy drives, this may not
always be desirable. In Solaris 2.4 and later, it is possible to
disable tagged queueing and set or clear other scsi options on a
per-controller or per-drive basis. The appropriate technique is
described in the esp(7) and isp(7) man pages.
_________________________________________________________________
5.6) Why don't third-party CD-ROMS work on my sun?
When Sun first decided to add CD-ROM support, there were already a
great number of systems in the field, all of which contained boot
proms that expected to boot from disks with 512 byte sectors. Sun had
to decide between replacing a whole lot of boot proms or finding a way
to make a CDROM act like a disk with 512 byte sectors in order to
support it as a boot device. They chose the latter approach.
Many third party CD-ROM drives use 1024 or 2048-byte sectors, which
causes the SCSI driver to see a "data overrun". When the driver asks
for N "blocks" (which it thinks are 512 bytes each ) it gets more data
back than it expected.
Some CD-ROM drives can be told to use 512 byte sectors by setting a
jumper, cutting a trace, or using a software command (mode select).
Details vary widely, but if you are seeing a data overrun on a third
party CD-ROM, then it is most likely doing 1K or 2K transfers and will
need some work to be a boot device for a Sun.
Thanks to Kevin Sheehan <Kevin dot Sheehan at uniq dot com dot au>
For more information about third-party CD-ROMS on Suns, consult the
CD-ROM FAQ, maintained by Mike Frisch <mfrisch at saturn dot tlug dot
org> and Martin Hargreaves <martin at datamodl dot demon dot co dot
uk>. It can be found on the World Wide Web at
""http://saturn.tlug.org/suncdfaq". A UK mirror is available at
""http://www.datamodl.demon.co.uk/suncd/".

5.7) What size and density parameters should I use for ufsdump with a
high-capacity tape drive?
The only purpose of the ufsdump size and density parameters is to let
char *dlerror()
{ return(NULL); }
int dlclose(handle)
void *handle;
{ return(0); }
_________________________________________________________________
4. Window Systems
_________________________________________________________________
4.1) + What Window system GUIs are supported by Sun?
Sun's default window system for Solaris is CDE; Gnome is also
supported. Sun's Java Desktop System and the Sunray software for Linux
uses Gnome.
_________________________________________________________________
5. Disks, Tapes and SCSI
_________________________________________________________________
5.1) * What sector/head/cylinders parameters should be used for a hard
disk?
The format program can almost always figure this out on its own by
querying the drive, but if you wish, you can specify your own in
/etc/format.dat.
A format.dat file containing entries submitted by various people is
available for anonymous ftp at
ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/format.dat It is
currently maintained by John DiMarco (jdd@cs.toronto.edu). New entries
are welcome; mail them to sunmanagers-format@sunmanagers.org
For SCSI disks on modern suns, a format.dat entry can be
auto-generated using John DiMarco's scsiinfo program, available at
ftp://ftp.cs.toronto.edu/pub/jdd/scsiinfo/. It will query the disk
directly, and has an option to generate an appropriate format.dat
entry.
Finally, you can compute your own entry. 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.
_________________________________________________________________
5.2) * Can I replace an internal drive in a Sun with a higher capacity
model?
Yes, usually. If you purchase it from someone other than Sun, it is
wisest to make sure that it is either a model of drive that is
supported by Sun for that machine, or that it at least does not
dissipate more heat than the hottest of the drives supported by Sun.
The Sun Systems Handbook lists various drives supported on various
models; you can query it on the web for modern Suns at
http://sunsolve.sun.com/handbook_pub/Systems. For systems which are
not maximally configured (e.g. there are empty internal drive bays),
it might be safe to exceed this limit a bit, but caveat emptor.
Disk drive heat dissipation/power figures are available on the drive's
datasheet, available on the drive vendor's web site. The most relevant
figure is the wattage indicated for "Read/Write" or "Seek".
Unfortunately, different vendors report this in different ways; read
the vendor's documentation to see what this figure indicates. This
figure is sometimes indicated in amps at 5V and 12V; convert to watts
by multiplying the voltage by the amperage in each case, and adding
the two together.

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.
Another possible cause of df & du disagreeing is if the files are
being 'hidden' under a mount. I ran into this recently where I
had a large number of files in /tmp (from adding patches in single
user mode) that were on the root partition. Thus when I was
looking for them in multiuser mode, I couldn't find them because
of the tmpfs overlay. I exported the root partition via NFS and
upon mounting it found the hidden files and deleted them.

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. Alternatively, for all modern Sun

will change to FIN_WAIT_1, side b) will change to CLOSE_WAIT, and
acknowledge the FIN packet. The acknowledgement causes side a) to
change to FIN_WAIT_2. A socket will rarely be in FIN_WAIT_1 for more
than a couple of seconds unless there is a problem with
communications. In this state, data may still be sent from side b) to
side a), but not vice versa. When side b) receives a close from the
associated application, or the FIN_WAIT_2_FLUSH_INTERVAL is reached
without data being sent, it will send a FIN and change to LAST_ACK.
Side a) moves to TIME_WAIT upon receiving this FIN and acknowledges
the packet, causing any references to this connection on side b) to
disappear. The socket in TIME_WAIT will remain for twice the maximum
segment lifetime (normally a total of four minutes) before dropping,
in case dropped data packets are resent and misinterpreted by a new
application on this port.

the basic principles of Solaris printing, documented at
http://developers.sun.com/solaris/articles/basicprinting.html, and the
Solaris printing FAQ, at
http://www.freelab.net/unix/sun/solarisfaq/printfaq.html. More
information about printing in Solaris is available at

(http://www.linuxprinting.org/database.html) to find out if a
ghostscript driver is available for your non-PS printer. Then you can
use ghostscript to translate postscript to something the printer can
understand. There are various "any2ps" scripts and packages around
(apsfilter, cups, foomatic, magicfilter). Ghostscript and foomatic are
bundled in Solaris 10.
the most recent version can be found at http://www.apsfilter.org. For
Solaris 2.x or later, you will need to add a BSD-style printing
package such as LPRng (http://www.lprng/org): the system-V-style "lp"
printing package that comes with Solaris will not easily work with
apsfilter. Thanks to Andreas Klemm <andreas at apsfilter dot org> for
this information.

2. Hit STOP-A or L1-A (or, on an ASCII terminal or emulator, send a
<BREAK>) to halt the operating system, if it's running.
3. Boot single-user from CD-ROM (boot cdrom -s) or network
install/jumpstart server (boot net -s) (NB: if it asks you for a
prom password, see below.)
4. Mount the root partition (e.g. /dev/dsk/c0t3d0s0) on "/a". "/a" is
an empty mount point that exists at this stage of the installation
procedure. (mount /dev/dsk/c0t3d0s0 /a)
5. Set your terminal type so you can use a full-screen editor, e.g.
vi. (you can skip this step if you know how to use "ex" or "vi"
from open mode). If you're on a sun console, type "TERM=sun;
export TERM"; if you're using an ascii terminal (or terminal
emulator on a PC) for your console, set TERM to the terminal type
(e.g. TERM=vt100; export TERM).
6. Edit the passwd file (/a/etc/passwd for SunOS 4.x,
/a/etc/passwd.adjunct for SunOS 4.x with shadow passwords/C2
security), /a/etc/shadow for Solaris 2.x and remove the encrypted
password entry for root
7. cd to /; Type "umount /a"
8. reboot as normal in single-user mode ("boot -s"). The root account
will not have a password. Give it a new one using the passwd
command.

security password mechanism in the PROM which can be set (this is
turned off by default). The man page for the eeprom command describes
this feature.
without the prom password from the default device (i.e. booting from
CD-ROM or install server will require the prom password). Changing the
root password in this case requires moving the default device (e.g.
the boot disk) to a different SCSI target (or equivalent), and
replacing it with a similarly bootable device for which the root
password is known. If security-mode is set to full, the machine cannot
be booted without the prom password, even from the default device;
defeating this requires replacing the NVRAM on the motherboard. "Full"
security has its drawbacks -- if, during normal operations, the
machine is power-cycled (e.g. by a power outage) or halted (e.g. by
STOP-A), it cannot reboot without the intervention of someone who
knows the prom password.
