Answers ----------------------------------------------------------------------------- 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@ra.mcs.anl.gov". 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". Messages can be posted to the list by mailing them to the address "sun-managers@ra.mcs.anl.gov". Do not do this until you have read the charter (question 1.2). 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) 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 (with a few small exceptions). 2: Requests to have addresses added or removed from the list should NOT be sent to the entire list. Instead, they should be mailed to: sun-managers-request@ra.mcs.anl.gov as described in the previous question. 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: Answers to questions are to be mailed back to the questioner and are NOT to be sent to the entire list. 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, it should contain the word "SUMMARY" as 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: COMMERICAL ADVERTISING of any sort on the list IS STRICTLY PROHIBITED. ABUSERS of this rule MAY BE BANNED from the list without notice. 8: Requests for software (free or otherwise) should be limited to software that is directly related to Sun SYSTEM MANAGEMENT ONLY. 9: Read the appropriate manuals BEFORE posting, including the "Read This First" documents. Often times the manuals contain answers for common problems. 10: 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 totally useless. Read eg. chapter 22 of the SunOS 4.1 system administration manual to learn how to produce a symbolic traceback. 11: 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 mentioned in answer 1.5. Perhaps your message would be more appropriate there. If after reading all the guidelines you decide that you still want to send your message to the entire sun-managers readership, then mail it to the address "sun-managers@ra.mcs.anl.gov". Failure to adhere to these guidelines may result in severe chastisement by the list maintainer and other 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 stupidity, you may end up damaging your professional reputation. ----------------------------------------------------------------------------- Subject: 1.3) Are there any archives for the sun-managers list? The site "www.LaTech.edu" archives every summary sent to the list. Questions are not archived. This site provides access to its archives via the HTTP (WWW), WAIS, and gopher protocols. It does not provide any anonymous FTP access. You can access the archives over the World Wide Web by referencing the URL "http://www.latech.edu/sunman.html" from any web browser. This is the preferred way to access the archives. 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 access to a wide variety of textual information. If your system already has a gopher client installed, you can access the sun-managers gopher by simply typing "gopher info.latech.edu". The sun-manager archives are accessible under the "archives" menu. 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 www.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. Nexial Systems in the Netherlands maintains a "fuzzy" full-text index of the Sun-managers mailing list at: http://www.nexial.nl/cgi-bin/sunmanagers ----------------------------------------------------------------------------- Subject: 1.4) What should I keep in mind when posting to sun-managers? o VERY IMPORTANT! Before you post, read the sun-manager's policy, which is available for anonymous ftp from ra.mcs.anl.gov in /sun-managers/policy. o 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 get 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. o 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. o 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. o 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. o 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. ----------------------------------------------------------------------------- Subject: 1.5) What other forums are there for Suns? Other forums that relate to Suns (please mail me corrections and additions): Newsgroups (accessible via "rn", "readnews", "nn", etc.): There is now an entire heirarchy devoted to Sun equipment: comp.sys.sun.admin Sun system administration comp.sys.sun.announce Announcements pertaining to Sun equipment comp.sys.sun.apps Applications that run on Suns comp.sys.sun.hardware Sun hardware (and clones too, I think) comp.sys.sun.misc Miscellaneous comp.sys.sun.wanted Sun stuff to buy or sell Other newsgroups that may also be of interest: comp.unix.solaris Solaris 2.x on all platforms alt.sys.sun may not be available everywhere comp.sys.sun newsgroup equivalent of sun-spots comp.sources.sun Sun-specific sources (not very active) Mailing lists: Sun Flash (Sun Product Announcements/news releases) sunflash-request@sunvice.East.Sun.COM add/remove requests Sunergy (Sun Commercial Newsletter) sunergy_information@Sun.COM add/remove requests Suns-at-home (Home use of Sun Workstations) Suns-at-Home-Request@net-kitchen.com add/remove requests Suns-at-Home@net-kitchen.com submissions Suns-at-Home-Archives@net-kitchen.com archive requests CIAC notes (US.

Do not send add requests to the main address! ----------------------------------------------------------------------------- 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. Sun recommended patches can be obtained from sun via anonymous ftp to sunsolve1.sun.com. 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 later releases. 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) archie.ncu.edu.tw 192.83.166.12 (Taiwan server) archie.nz 130.195.9.4 (New Zealand server) archie.th-darmstadt.de 130.83.22.1 (Germany server) archie.switch.ch 130.59.10.40 (Switzerland server) archie.unipi.it 131.114.21.10 (Italy server) archie.ac.il 132.65.16.8 (Israel 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. An HTML version can be obtained at ftp://ftp.fwi.uva.nl/pub/solaris/solaris2.html. ----------------------------------------------------------------------------- 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 can be found on gatekeeper.dec.com (16.1.0.2) in /pub/BSD/UCB/bind.4.8.3.tar.Z. resolv+ is on osl.csc.ncsu.edu (152.1.58.11) in pub/unix/sun/resolv+-2.1.tar.Z. A later version is available at emx.cc.utexas.edu:/pub/mnt/source/tcp-ip/resolv+2.1.1/resolv+2.1.1.tar.Z The latest version of bind is available from gatekeeper.dec.com (16.1.0.2) in /pub/misc/vixie. ----------------------------------------------------------------------------- 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? 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 steps: 1) Login as root for the system and change the root password in the /etc/shadow file: {root}3% passwd passwd: Changing password for root New password: Re-enter new password: {root}4% 2) Change the system's private key in the cred table: {root}4% chkey -p Updating nisplus publickey database. Reencrypting key for 'unix.ramayan@bharat.i n'. Please enter the Secure-RPC password for root: Please enter the login password for root: {root}5% 3) If running replica server(s) then wait until the changes to the credential object table has been propagated to its replicas. This could be up to 2 minutes. 4) Change the system's /etc/.rootkey: {root}5% keylogin -r Password: Wrote secret key into /etc/.rootkey {root}6% The procedure above will work for any system -- root server, root replica, non-root servers, and all clients. The steps above change only the system's root password and private keys, not the public keys for the system. Thanks to Ronald W. Henderson . However, if you want to change all the root credentials, including the public key, follow these steps: 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 public 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. 4. 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 2213 for this information. ----------------------------------------------------------------------------- Subject: 3.8) When I compile something, errors occur saying _dlopen and the other _dl routines can't be found. Why? If your system is running SunOS 4.x, your System Administrator has modified the C library (/usr/lib/libc.a), usually to add hooks for hostname resolution (DNS). This modification is usually made using packages like "bind 4.8.3" or "resolv+ 2.1". Unfortunately there is a bug in that process which is documented but frequently missed by the person doing the installation. There are two ways around this: (i) Specify -ldl when compiling any and all package that complains. (ii) Get the sys-admin to reinstall the libc properly, ensuring that the Makefile used in that process specifies -ldl, so that the dl routines are included. Thanks to markus@octavia.anu.edu.au (Markus Buchhorn) for this answer. Sometimes other routines are also noted as not being found. There are three .o files in the shared library (rpc_commondata.o, rpc_dtablesize.o, and xccs.multibyte.o) that have names longer than 14 characters. These are unpacked during the shared library customization procedure as files without the trailing 'o', and need to be renamed so that the trailing 'o' is present. Ask the sysadmin to fix this. If you are running Solaris 2.x, you are probably trying to compile something statically. You must either include stub routines for the _dl routines, or you must link the C library (or -ldl) dynamically. ----------------------------------------------------------------------------- 4. Window Systems ----------------------------------------------------------------------------- Subject: 4.1) Can I run both OpenWindows and MIT X11? In Solaris 2.x, they both work without conflict. In SunOS 4.x, things are a bit more complicated: 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 necessary.) Sun OpenWindows set path = (/usr/openwin/bin /usr/openwin/demo $path) setenv LD_LIBRARY_PATH /usr/openwin/lib (Actually, for most OpenWindows clients, it's sufficient to set OPENWINHOME to /usr/openwin instead of setting LD_LIBRARY_PATH. Setting LD_LIBRARY_PATH to /usr/openwin/lib may cause MIT clients to fail.) You can also run clients from one environment under a different server on a one command at a time basis. This example runs a OpenWindows client under the MIT server: (setenv LD_LIBRARY_PATH /usr/openwin/lib; x_soundtool) It is possible to run OpenWindows 3.0 and MIT X11 simultaneously without having to toggle LD_LIBRARY_PATH as above, by putting the X11 libraries before the openwindows libraries in LD_LIBRARY_PATH, and the X11 binaries before the openwindows binaries in PATH, as follows: setenv LD_LIBRARY_PATH /usr/lib/X11:$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 X11R4 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 Unfortunately, not all OpenWindows 3.0 applications will work with X11R5 libraries. 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 necessary. 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 /R5contrib ----------------------------------------------------------------------------- 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:/R5contrib and apply it. Configure and compile as per the patch instructions. ----------------------------------------------------------------------------- Subject: 4.3) Why does my OpenWindows File Manager abort with a "mknod: permission denied"? Under Solaris 2.3, the first time filemgr is launched, it created a /tmp/.removable directory owned by the user who launched it. If a different user later starts up filemgr, it will try to create /tmp/.removable, but that directory will already exist from the last time, owned by the previous user, so the attempt will fail. Fix by installing patch 101514-02. ----------------------------------------------------------------------------- 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: Fujitsu America BBS 408 944 9899 Seagate BBS USA/Can 408 438 8771 Seagate BBS England 44 62 847 8011 Seagate BBS Germany 49 89 140 9331 Seagate BBS Singapore 65 292 6973 Seagate BBS Australia 61 2 756 2359 Maxtor BBS 303 678 2222 Micropolis BBS 818 709 3310 Quantum BBS 408 894 3214 Conner BBS 408 456 4415 / 408 456 3200 It is also possible to contact drive manufacturers by telephone.

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@ra.mcs.anl.gov 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 sells drives significantly larger than 700MB, and 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.

Kuhn). ----------------------------------------------------------------------------- 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. Stan Hoffman adds: I also found a lot of bad connectors where the power cable connects to the motherboard. The connector coming from the drive have horseshoe-shaped clips that straddle the wire and cut into it to make contact. I have often had to reseat these clips by pressing them down a little further before the drive would power up. ----------------------------------------------------------------------------- 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 and later) 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 and later, 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? For Solaris 2.x, this is trivial. For SunOS 4.x: 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). ----------------------------------------------------------------------------- Subject: 5.10) How do I configure my sun to use Exabyte 4mm DAT tape drives? According to Exabyte's customer service center (913-492-6002), for SunOS 4.1.x, for an EXB-4200 and 4200c, add the following entries to /sys/scsi/targets/st_conf.c: /* Exabyte 4mm 2GB cartridge */ { "Exabyte EXB-4200 4mm Helical Scan", 16, "EXABYTE EXB-4200", ST_TYPE_DEFAULT, 1024, (ST_VARIABLE | ST_BSF | ST_BSR), 5000, 5000, { 0, 0, 0, 0 }, { 0, 0, 0, 0 } }, /* Exabyte 4mm 4GB w/compression cartridge */ { "Exabyte EXB4200c 4mm Helical Scan", 17, "EXABYTE EXB-4200c", ST_TYPE_DEFAULT, 1024, (ST_VARIABLE | ST_BSF | ST_BSR), 5000, 5000, { 0x63, 0x43, 0x0c, 0x0c }, { 0, 0, 0, 0 } }, For Solaris 2.x, 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 . ----------------------------------------------------------------------------- Subject: 5.11) Why is tagged queueing a problem on my third-party SCSI disk under Solaris 2.x? 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.cdf.toronto.edu/pub/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. ----------------------------------------------------------------------------- Subject: 5.12) 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. For more information about third-party CD-ROMS on Suns, consult the CD-ROM FAQ, which is posted periodically to comp.sys.sun.hardware. Thanks to Kevin Sheehan ----------------------------------------------------------------------------- Subject: 5.13) How do I support Exabyte 8505C 8mm tape drives on SunOS 4.x? Modify /usr/sys/scsi/targets/st_conf.c to add the following entry: /* Exabyte 8mm 5GB 1/2-height cartridge, with compression */ { "Exabyte EXB-8505 8mm Helical Scan", 16, "EXABYTE EXB-8505", ST_TYPE_EXB8500, 1024, (ST_VARIABLE | ST_BSF | ST_BSR | ST_LONG_ERASE), 5000, 5000, { 0x14, 0x90, 0x15, 0x00 }, { 0, 0, 0, 0 } }, Create a new kernel and boot using it. The devices corresponding to the different modes supported by the drive are as follows: Device Capacity Emulation st0,st1 2.3GB Exabyte 8200 st8,st9 2.3GB with compression Exabyte 8200C st16,st17 5GB Exabyte 8500/8505 st24,st25 5GB with compression Exabyte 8505C Thanks to Paul Roland Note: Exabyte 8505C 8mm support is included in SunOS 5.x a.k.a. Solaris 2.x, so no special modifications are required for OS versions later than 4.x. ----------------------------------------------------------------------------- Subject: 5.14) + What size and density parameters should I use for dump with a high-capacity tape drive? The only purpose of the dump (ufsdump in Solaris 2.x) size and density parameters is to let dump calculate the capacity of each tape and then decide for itself when it needs a new tape. If the filesystem you are dumping is larger than the tape, you will need to use more than one tape. In SunOS 4.x and earlier, dump uses the size and density parameters to decide when to stop writing to a particular tape and prompt for a new one. Since SunOS 4.x has a filesystem limit of 2GB, it is most often the case, for modern high-capacity tape drives, that the filesystem will fit on one tape. If, as is the case with SunOS and high capacity drives, you are dumping multiple filesystems one after another to the non-rewinding tape device, each successive dump has no way of knowing how much of the tape has been already used, so there's no recourse but human intervention. In other words, you have to figure out manually how many of your filesystems will fit on one tape. All that the dump size and density parameters do is tell dump that it has lots of space left. Since it hardly matters what these parameters are, so long as they convince dump that the (remainder of the) tape is bigger than your filesystem so that it doesn't decide to ask you for a new tape part-way through, you can tell it the tape is big enough for a 2GB filesystem, by using 16000 for both the size and density parameters. This will be large enough for all standard SunOS 4.x filesystems. If you're using Online Disk Suite or something similar to overcome the 2GB SunOS filesystem size limit, these parameters will need adjusting. For example, if you need to dump a 4 Gbyte filesystem, simply double the tape size. In Solaris 2.x, ufsdump can detect the end of media for all modern tape drives, and will automatically prompt for new tapes when needed. Thanks to Niall O Broin ----------------------------------------------------------------------------- 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. "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. Top is available for anonymous ftp at eecs.nwu.edu in /pub/top. A version of Sps that runs on Solaris 2.x is available at ftp.csv.warwick.ac.uk in /pub/solaris2/sps-sol2.tar.gz. 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. The commands "pstat -s" (for 4.x) or "swap -s" (for Solaris 2.x) will tell you how much virtual memory is available. 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. "/usr/etc/devinfo -v" is informative on some machines. 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 available 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. ----------------------------------------------------------------------------- Subject: 6.5) * Why do some files take up more disk space after being copied? Why are the sizes reported by ls -l and du different? Some files -- core files being one common example -- contain "holes", areas which were seeked over without being written. These files are called "sparse". When read back, these areas appear to contain zeros; however they do not occupy disk space. The "length" of such a file (as reported by "ls -l") will exceed its "size" (as reported by "ls -s" and reflected in the results of du or df). cp, cpio, and tar do not detect holes; they read and copy the zeros, and the resulting files will contain all-zero blocks (which occupy space) where the input files contained holes (which do not). dump will detect holes in the dumped files, and restore will reproduce them. GNU tar has an "-S" option which preserves holes. Thanks to Perry Hutchison ----------------------------------------------------------------------------- 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. For Solaris 2.x, see the ftpd(1m) man page, and follow its instructions. You will also need to set up nsswitch.conf in etc. ----------------------------------------------------------------------------- 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 Warning: it will log passwords of ordinary users. 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.x? Don't do it with xmodmap, since that won't change the locking behaviour of CAPS LOCK. Edit $OPENWINHOME/etc/keytables/US5.kt. There are two places where keys 119 (CapsLock) and 76 (Control) should be swapped: the MODMAP section and the KEYSYMMAP section. The latter is most important, because that's where the "Pseudo-Lock" function (which controls the locking behaviour of the key) is defined. Thanks to Margarita Suarez for the answers to this and the previous question. ----------------------------------------------------------------------------- Subject: 8.3) How do I use the keyboard and display when the console is on ttya? This technique is usable only on SunOS 4.x: /dev/mouse and /dev/kbd are disabled when you use ttya or ttyb for a console. You need to make new ones, which you can use with xdm to support the keyboard and display while the console is on the serial port. Here's how: 1. Make new special files corresponding to the "raw" kbd and mouse: mknod /dev/zs2 c 12 2 # The keyboard mknod /dev/zs3 c 12 3 # The mouse These are just serial ports and will need some "special treatment" in order to behave as /dev/kbd and /dev/mouse. 2. Shutdown your machine and tell the monitor to use ttya (or ttyb) setenv input-device ttya setenv output-device ttya (or use the eeprom command to do this) 3. Reset and reboot. /dev/fb, /dev/kbd and /dev/mouse are now useless. /dev/bwtwo0 (or whatever your framebuffer device is) works as a substitute for /dev/fb. Also /dev/ttya (or ttyb) is useless - if you have an entry in ttytab for it, comment it out. 4. Modify the StartOW file in the xdm directory ($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? SunOS 5.x = Solaris 2.x 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 through 5.4 4/300 series: SunOS 4.0.3 through 5.4 4/400 series: SunOS 4.1PSR_A through 5.4 600 models 120, 140: SunOS 4.1.2 or later. 600 model 41, 51: SunOS 4.1.3 or later. SPARCstation 1, 1+, SLC, IPC: SunOS 4.0.3 or later. SPARCstation 2, ELC, IPX: SunOS 4.1.1 or later. SPARCstation 4: SunOS 4.1.4 or later. SPARCstation 5: SunOS 4.1.3_U1B or later. SPARCstation 10 models 20, 30, 40, 41, 51, 61, 71: SunOS 4.1.3 or later. SPARCstation 20 models 50, 51, 61, 71: SunOS 4.1.3_U1B or later. SPARCstation 20 model HS11, HS21, 151: SunOS 4.1.4 or later. SPARCclassic, SPARCstation LX: SunOS 4.1.3C or later. SPARCstation Voyager: Solaris 2.3 edition II or later. Ultra 1 model 140, 170: Solaris 2.5 or later. Ultra 1 model 170E: Solaris 2.5.1 or later. The following machines only run Solaris 2.x: SPARCserver 1000, 1000E, SPARCcenter 2000, 2000E, Voyager, all Ultra systems. The SX framebuffer on the SS10 and 20 is only supported under Solaris 2.x. SunOS 4.1.3 and later has been reported to run on multiprocessor SuperSPARC configurations of the SS10, SS20, and 600, 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. Note that SS20, Classic, LX, Voyager and later systems do not come with a right-to-use license for 4.1.x; this needs to be purchased separately. SunOS 5.0 runs only on SS1,1+,2,SLC,IPC,ELC,IPX. While SunOS 5.x does run on the 4/100 and 4/200 systems, the FPU (if present) is disabled, and floating point is emulated in software. The latest version of SunOS 5.x (Solaris 2.x) that runs on the 4/100, 4/200, 4/300, and 4/400 systems is 5.4 (Solaris 2.4). SunOS 5.3 (aka Solaris 2.3) is said to run on the SS5, but without support for the audio device. Solaris 2.3 Edition II, Solaris 2.3 Hardware 5/94, and later versions include audio support. Not all peripherals supported under SunOS 4.x are supported under SunOS 5.x and vice versa. 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 1.1C = SunOS 4.1.3C + Open Windows 3.0 (Classic/LX only) Solaris 1.1.1 = SunOS 4.1.3_U1 + Open Windows 3.0_U1 Solaris 1.1.1revB = SunOS 4.1.3_U1revB + Open Windows 3.0_U1revB Solaris 1.1.2 = SunOS 4.1.4 + Open Windows 3.0 (?) 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 Solaris 2.4 = SunOS 5.4 + Open Windows 3.4 Solaris 2.5 = SunOS 5.5 + Open Windows 3.5 ----------------------------------------------------------------------------- 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 Alternatively, grab Michael Cooper (mcooper@usc.edu)'s "sysinfo" program, which provides all sorts of information about a given system, including how much machine type. sysinfo is available for anonymous ftp from usc.edu in /pub/sysinfo. ----------------------------------------------------------------------------- Subject: 9.3) What MBUS CPU modules are available? How can I tell what module(s) is/are in what model of SS10/SS20/SS600? Three sun models, the SS10, SS20 and the SparcServer 600 series, support Sun's MBUS. All these machines have two MBUS slots. Both modules must be of the same type. SuperSPARC/w cache modules of different speeds are said to work, as are three-processor systems (by combining a single and a dual module of the same type), but such configurations are not supported by Sun. Modules without external cache are not separately clocked, and run at the clock rate of the MBUS. Modules with external cache are separately clocked, and must run at a clock rate higher than that of the MBUS. The SS20 has a switchable 40/50MHz MBUS, the SS600 has a 40MHz mbus, and the SS10 has a switchable 33/36/40MHz MBUS. Warning: different module revisions may or may not work in different systems. Check the Sun part number. Further, newer modules may require that the machine have a sufficiently recent PROM revision to work.

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. ----------------------------------------------------------------------------- Subject: 10.3) Various daemons report "unknown service" messages. Why? In SunOS 4.x, this is usually caused by a blank line in /etc/services or in the services map on the NIS server. Remove all blank lines from /etc/services, and the problem should be resolved. ----------------------------------------------------------------------------- Subject: 10.4) Solaris 2.x does not have a C compiler. Where can I get one? You can buy one from Sun and various third-party vendors. A very old version of GCC is available on the Sun Catalyst CD-WARE #3 CD-ROM under Cygnus. This version should only be used to compile a more recent version of GCC. Recent GCC binaries can be retrieved from the following FTP sites: 0) ftp://prep.ai.mit.edu/pub/gnu/sparc-sun-solaris2/ 1) ftp://ftp.lanet.lv/pub/unix/solaris2/ 2) ftp://nic.switch.ch/mirror/gnu-sparc-solaris/ This site is said to contain several programs/libraries for Solaris2.X. (i.e. gcc, emacs, gdb, libg++, gawk, diff, make, sed) 3) ftp://sunsite.unc.edu/pub/gnu/solaris-pkgs/ 4) ftp.quintus.com/pub/GNU/sparc/ Thanks to Kevin Inscoe ----------------------------------------------------------------------------- 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. Alternatively, you may have an old mouse. martin@gea.hsr.it (Martin Achilli) writes: Sun optical mice P/N 370-1170-01 have two LEDs on the underside. One is a normal red LED, the other is an infrared LED. Old mice (4+ years) can have trouble tracking horizontal motion. Cleaning the mouse pad with a solvent may improve things slightly but not completely. I have replaced the red LED on the mouse PCB for eight of my twelve optical mice and the problem has gone. All you need to do is purchase a red LED of the type than focus the beam, NOT the unfocused type that are normally found as indicator lights on equipment. Open the mouse and remove the PCB by unplugging the small black connector. Be careful with the two small spherical lenses which can fall out and easily be lost. Mark the PCB and one of the LED's leads to note the orientation, then desolder the LED marked L1. Pull out the leads from above and pull the LED out of the black plastic mounting. Be careful since the mounting is only glued to the PCB. Check for polarity before inserting the new LED, I noticed that for all the LEDs that I installed, the longer lead must go into the PCB hole close to the letters L1. First fold the LED leads like the ones of the one you are replacing, and then insert it into the mounting, solder the leads and close the mouse. After this, horizontal motion should be much smoother. Disclaimer: I will not take any responsibility for any failure or damage arising from the above procedure Thanks to Martin Achilli . ----------------------------------------------------------------------------- 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) These parts are available from various resellers. ----------------------------------------------------------------------------- 12. Networking ----------------------------------------------------------------------------- Subject: 12.1) Why do both my net 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. ----------------------------------------------------------------------------- 13. Electronic Mail ----------------------------------------------------------------------------- Subject: 13.1) Where can I get a POP or IMAP server for my sun? The PINE email package comes with both a POP and an IMAP server. PINE can be found at ftp://ftp.cac.washington.edu/pine/. An old, unmaintained Berkeley popd can be found at ftp://ftp.cc.berkeley.edu/pub/pop (not recommended), and Casper Dik's enhanced version for Solaris is found at ftp://ftp.fwi.uva.nl/pub/solaris/. A POP server can also be found as part of the Eudora ftp repository, at ftp://ftp.qualcomm.com/quest/unix/servers/ Finally, the CMU Cyrus IMAP server can be used. It can be found at ftp://ftp.andrew.cmu.edu/pub/cyrus-mail.
