Answers 1) How to get DNS working when not running NIS ? The "normal" behavior of a hostname lookup under NIS is to consult the NIS hosts map and then DNS (if configured). If you are not running NIS the system will only look in the /etc/hosts file. You have two options to correct this situation: A) Re-build shared libraries by installing the shlib custom option and one of the many "bind" resolver library packages available for SunOS. You can only do this if you are running SunOS version 4.1 or greater. If you want to do it under 4.0.3 you need to get the patches available from ftp.uu.net in /systems/sun/sun-fixes. The files you will need are as follows: 1) lib.msg 2) libc_pic.a.sun3 or libc_pic.a.sun4 3) libc_resolv.so.sun3 or libc_resolv.so.sun4 There should be a README in the same directory explaining what these files are. B) Run NIS with the "hosts" maps only. Option A is the "hardest" to implement. It requires that you change all the shared libcs on the all machines that you want name resolving on. Also, it "breaks" several statically linked commands such as mount and rcp. If you are under Software maintenance you may be able to get a "dynamically" linked "mount". Complete directions for installing DNS without NIS can be found in the bindon4.1.shar file or the resolv+ tar file. Here is a list of the software one can use to modify your shared libraries to use DNS without NIS. bindon41.shar is on qiclab.scn.rain.com in the file /pub/network/bindon41.shar.Z bind 4.8.3 is on okeeffe.cs.berkeley.edu in the file /4.3/bind.4.8.3.tar.Z resolv+ is on liasun3.epfl.ch in file /pub/net/dns/resolv+-2.1-beta.tar.Z Note: that you can still use NIS for other things in environment, such as passwd, and group maps. Option B is the "easiest" of the two to implement. It just requires you to run NIS and change the "all" line /var/yp/Makefile to "all: hosts". Also, it does not require any change to the shared libraries. It does not "break" anything. You can install operating system patches that require updating the shared libraries without having to remake the shared libraries. 2) How to get DNS to be used when running NIS ? First setup the appropriate /etc/resolv.conf file. Something like this should do the "trick". ; ; Data file for a client. ; domain local domain nameserver address of primary domain nameserver nameserver address of secondary domain nameserver where: "local domain" is the domain part of the hostnames. For example, if your hostname is "thor.ece.uc.edu" your "local domain" is "ece.uc.edu". You will need to put a copy of this resolv.conf on all NIS(YP) servers including slaves. Under SunOS 4.1 and greater, change the "B=" at the top of the /var/yp/Makefile 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; \ 3) How to properly setup NFS mounting of /var/spool/mail ? On the Client machines: A) mount /var/spool/mail with the no attribute caching option. An example, fstab line would be the following: mailhost:/var/spool/mail /var/spool/mail nfs rw,noac 0 0 B) Use a sendmail.cf that forces all mail to be delivered by the mailhost. One such file is available via anonymous ftp to thor.ece.uc.edu. Get the file /pub/sun-faq/sendmail.client.cf Do not use the OR option that Sun provides. It is broken in many ways. On the server machine: A) Setup MX records pointing to the mailhost for all client machines. B) Edit the /etc/exports file to export /var/spool/mail to the mail client machines. You may want to use a netgroup for this purpose. C) Setup the /etc/sendmail.cf on the server recognize that mail to/from a client is "local". One such file is available via anonymous ftp to thor.ece.uc.edu. Get the file /pub/sun-faq/sendmail.server.cf Note: You may want to install IDA sendmail instead of Suns stock sendmail. 4) Can I use AnswerBook under X11R5? AnswerBook in its current form requires the Openwindows server. It uses the NeWS extensions(Postscript) extensions to this server to display the Answerbook files. To use AnswerBook under X11R5 you will need to replace the docviewer program with xdocviewer. Xdocviewer does not support all the options that the "real" docviewer supports such as "hypertext" links. To install "xdocviewer" you will need the following programs. Perl-4 patchlevel 35 Ghostscript 2.4 or above GSpreview 2.1 or above or Ghostview 1.3 or above All of these are available from prep.ai.mit.edu. They are located in the /pub/gnu directory. Finally, You need xdocviewer. It is available from the /contrib directory on host export.ai.mit.edu. 5) What does "NFS write error X" mean? You can lookup the error codes in /usr/include/sys/errno.h. Two common NFS error codes are 13 - "permission denied" and 70 - "stale file handle". Error code 13 can occur from incorrect /etc/exports entry. Also, it can occur because someone has changed the /etc/exports entry to disallow the client after the client has already been granted permission to perform this operation. Error code 70 occurs when a fileserver gets rebooted and the server NFS "file handle" for a particular filesystem changes. The "file handle" can be changed under the following circumstances. A) Installing a new drive in place of an old. B) Moving a filesystem from one devices to another. C) Performing a format, newfs, dump, and restore cycle. Even if to the same device. You can usually get rid of the error by unmounting and remounting the filesystem in question. Also, error code 70 can occur when someone removes a file that a process is actively writing from a NFS client machine. Under SunOS 4.1, you can run "showfh" 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. You will need a patch to get "showfh" to work correctly. The patch id is 100371 and this patch is required for 4.1, 4.1.1, and 4.1.2. Sun claims that its been integrated into 4.1.3. 6) How do I find the amount of memory installed or other system configuration information? You can use the "devinfo" command to find out general information about the hardware attached to your Sun. The "devinfo" command is only available on desktop SPARCsystems, SPARCengine 1E(although not in the version used in Auspex Systems), or 600MP series server only. The "best" command for the job is "sysinfo". Sysinfo is public domain utility available via "anonymous" ftp on usc.edu in directory /pub/sysinfo. Sysinfo works on all Sun architectures(inculding Sun-3s) as well as many other UNIX boxes such as Ultrix, and Next. Sysinfo does not run on SunOS 5.0. For SunOS 5.0 you can use sysdef. Note: "wc -l /dev/mem" and "dd if=/dev/mem of=/dev/null" and the like will *not* give the correct answer on machines where physical memory is not contiguous, such as many Suns. 7) Where can I get a version of ftp that does logging? There are at least 2 versions that have enhanced logging or can be modified to enable logging: wuarchive.wustl.edu (128.252.135.4) /packages/ftpd.wuarchive.shar pprg.unm.edu (129.24.24.10) /pub/misc/unm-ftpd.tar.Z The most widely used is the "wuarchive" version. The stock Sun ftpd will log some information if you add the "-l" flag in /etc/inetd.conf: ftp stream tcp nowait root /usr/etc/in.ftpd in.ftpd -l Also enable syslogd by adding: daemon.info /var/adm/syslog to "/etc/syslog.conf". 8) Where can one get SunOS patches? Where can I get patch 100xxx-xx? Many anonymous ftp sites have partial collections of patches. These sites include the following: princeton.edu:/pub/sun-fixes qiclab.scn.rain.com:/pub/sunos-patches iskut.ucs.ubc.ca:/pub/ubc/sun-patches/ ftp.uu.net:/systems/sun/sun-dist/ princeton.edu has patches for SunOS, AnswerBook, Openwindows, lang, and PC-NFS. qiclab.scn.rain.com has several hundred patches available for SunOS only. iskut.ucs.ubc.ca has several of the newer patches. ftp.uu.net is the "official" distribution point for SunOS security patches. Also, you should use "archie" to look for specific patches. Finally, the Sun User Group (SUG) CD ROM has a collection of Sun patches. 9) How to setup Opewindows Calendar Manager in a distributed environment? Sun's original assumption that each user has a permanent machine allocated to them is not applicable in most environments. Just as users send mail to 'user' rather than 'user@machine', users want to browse others user's calendars and do not care or want to know where the calendar is actually stored. Here is procedure to accomplish our goal. All calendars will be stored on a central server. The initial setup must be down on the server. A) Have the user login to the calendar host(calhost) machine. B) Change everyone's .cm.rc file so that Calendar.DefaultCal points to user@calhost calhost can be an hostname alias or an actual hostname. You may want to use the alias just in case you change the "calhost" later. C) Change their Access List and Permissions (under Edit/Properties) to show user@client with BID (browse, insert, delete) permissions for any client machine the user wanted to access their calendar from. Notes: If you use the scheme you should not NFS mount /var/spool/calendar on the client machines. 10) Why does the talk command fail between SunOS and any other manufacturers equipment(like DEC)? SunOS has the old BSD 4.2 version of talk. The old talk uses "machine dependent" byte ordering. Since DEC has different byte order the two talks can not communicate(even if you use "otalk" on the DEC machines). Also, most vendors have the newer version of talk from BSD-4.3 and this version is not compatible with the Sun Version(which is BSD-4.2). The solution is to get and install the new version of talk because it uses "network" byte ordering and it is compatible with most Vendors current talk implementations. "New Talk" is available via anonymous ftp from several sites including thor.ece.uc.edu(Get the file /pub/sun-faq/ntalk.tar.Z). 11) How do I setup "anonymous" ftp? 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. Note: For SunOS versions 4.1.2 and 4.1.3 you will need to copy /usr/lib/libld.so.* to the ftp area as well. You can use a "statically" linked binary from the GNU fileutils instead of the "dynamically" linked SunOS version. You can get the GNU fileutils from prep.ai.mit.edu in the directory /pub/gnu A complete procedure to setup anonymous under SunOS is available via anonymous ftp to thor.ece.uc.edu. Get the file /pub/sun-faq/anon-ftp.how-to. 12) 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". Also, you should use the complete path to rpc.yppasswdd For example: /usr/etc/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. 13) What does NFS getattr failed/RPC: Authentication error mean? You are probably running a pre-4.0 version of NFS 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. 14) Why did my Quantum 105 megabyte hard disk stop working? This the now infamous Quantum drive "stickation" problem. If the drive is allowed to cool down(even for a short period of time) the drive lubricant will congeal and prevent the disks platters from rotating. Before you get a replacement, try lightly tapping the drive to loosen the lubricant. If this does not work try shaking and twisting the drive at the same time. One last thing to try is to lift the system up a couple of inches and drop it. 15) Can I replace the 105 megabyte internal drive with a higher capacity model? The higher capacity drives create more heat and draw more power than the 105S. The case cooling ability and power supply in the SS-1 and SS-1+ are not adequate for the 210 megabyte or higher capacity drives possible in the SS-2. 16) How can I turn my Sun3 into an X-Terminal? You can use Seth Robertson's Xkernel package. It 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. If you are in hurry get the 4LAZY.sun3.tar.Z file. It contains all the necessary software to get Xkernel up and running. Xkernel 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. Finally, a used 3/50 is competitive with low-end X Terminal 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 might be higher for sun3 hardware. 17) Why is my console login prompt garbled or in some strange alphabet after upgrading to 4.1.3? The problem is /etc/ttytab, with 4.1.3, the console is now able to display 8 bits characters and getty must take this into account. The solution is easy, replace your console entry in /etc/ttytab by the following, the important part is 'cons8': console "/usr/etc/getty cons8" sun on local secure Also, if you did an upgrade(instead of a full install) you may need to add the following to your /etc/gettytab. # This is a new entry to internationalize the console. It needs to be # 8 bit clean so that ISO 8859 characters can be displayed without # the window system. # cons8:\ :p8:lm=\r\n%h login\72 :sp#9600: 18) Why are there "random" missing services at boot time(even though the services are in the /etc/services file or NIS map)? The two primary causes for "random" missing services are as follows: A) "Blank" lines in /etc/services. This is the primary cause. B) NIS/YP server not responding quickly enough to the "getservbyname" call. The only fix is to replace the systems version of inetd with a version that re-tries a "unknown" service. I have "hacked" a version of munetd(public domain replacement for inetd) to do this. It is available from thor.ece.uc.edu. Get the file /pub/sun-faq/munetd.tar.Z Another suggestion that has worked for some people is to add the following to your rc.local(right after ypbind is started): ypwhich > /dev/null 2>&1 This will force ypbind to bind. 19) Where can I get Data Certified tapes for 8-mm tape drives(at reasonable price)? Here is an incomplete list of vendors how have "data certified" tapes for the exabyte. Misco 800-876-1726 $12 - 15 each. TecBridge 800-972-7405 $12 - 15 each. R-Squared 800-777-3478 Sony 112m 120@8.00 Each K and K Systems 612-475-1527 $10 Each SCR 314-739-0808 $10.95 for Memorex 20) What is "archie"? Archie is a database of what is on several thousand anonymous ftp sites. To use archie get one of the three archie clients which are as follows: xarchie - For use under X11 c-archie - Curses version of Archie archie - Perl Version of Archie Theses are available from archie.ans.net in the directory /pub/archie. List of other publicly available archie servers: archie.rutgers.edu 128.6.18.15 (Rutgers University) archie.unl.edu 129.93.1.14 (University of Nebraska in Lincoln) 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) archiecs.huji.ac.il 132.65.6.15 (Israel server) 21) How do I synchronize time on my Sun Network? You should use xntp version 3 to synchronize your time. Xntp synchronizes to "atomic" and/or Radio Frequency clocks. Using xntp time should always be within a few "milliseconds" of the actual time. xntp is available from udel.edu. Get the file /pub/ntp/xntp3.tar.Z 22) What is the phone number for Sun Express or other important Sun phone numbers? Sun Express: 1-800-USE-SUNX (1-800-873-7869) Main Sun Helpline: 1-800-USA-4SUN (1-800-872-4786) 23) How do I join sun related mailing lists? Mailing Lists: Sun Managers: Used for "emergency" information only. The users of this list are "very" knowledgable. sun-managers-request@eecs.nwu.edu add requests sun-managers@eecs.nwu.edu submissions Sun-386i: discussion about the Sun 386i product sun-386i-request@mailhost.acq.osd.mil add requests sun-386i@mailhost.acq.osd.mil submissions Suns-at-home: discussion about maintaining Sun2/3/4/4c systems at home suns-at-home-request@orchestra.ecn.purdue.edu add requests suns-at-home@orchestra.ecn.purdue.edu submissions Auspex: managers of Auspex NFS file servers auspex-request@princeton.edu add requests auspex@princeton.edu submissions Epoch: managers of Epoch NFS file servers EPoch Users Forum (EPUF) epuf-request@mcs.anl.gov add requests epuf@mcs.anl.gov submissions sun-flash: Provides articles about Sun products and services. Subscription request should be sent to sunflash-request@sunvice.East.Sun.COM NOTE!!! if you wish to be added to one of the above mailing lists, send mail to the REQUEST address! Do not send add requests to the main address! 24) How do I use Mac floppies in a SUN drive? The easiest way is to use suntar on the Macintosh to copy files to a "high density" floppy. Then you can use "tar" on the Sun to get the files off the floppy. It is available from sumex-aim.stanford.edu. Get the file /info-mac/util/suntar-131.hqx Also, you could use the Apple File Exchanger to translate the files to MS-DOS format. Then use one of the methods for transferring MS-DOS disks to Sun. Note: There are several commercial packages available for this purpose. Also, low density Mac floppies are not comparable with low density Sun floppies. 25) How can transfer floppies back and forth between MS-DOS and Sparc? There are two packages which allow you to do this(mtools and mntdsk) Mtools writes directly to the floppy device and it does not require special privileges. It is faster than mntdsk but it requires the user to learn a new set of commands. mntdisk "mounts" the floppy using the "pcfs" filesystem type. Once mounted you can use regular UNIX commands(cp,mv,and rm) to access it. A copy of mtools can be found on thor.ece.uc.edu. Get the file /pub/sun-faq/mtools-2.0.7.tar.Z Mntdisk is available in your local comp.sources.misc, Volume 22, Issue 31. Mntdsk can be used to mount CD-ROMS and even UFS floppies. Note: You should not use "setuid" shell scripts for mounting floppies. 26) Why is my biff not "biffing" when using biff in a networked environment? In its current form comsat/biff are only usable on the mail server. You need to replace them network capable programs. A shar file containing network capable versions of comsat and biff is available from thor.ece.uc.edu. Get the file /pub/sun-faq/biff-comsat. 27) How do I disable L1-A(STOP-A) or re-map it? You need to get one of the many re-mapping programs. Two of these are available from thor.ece.uc.edu. Get the file disable-L1-A.tar.Z 28) Why are all the local users "unknown" when using sendmail under 4.1.2? There is a known problem with sendmail and frozen config files under 4.1.2. The fix is to remove /etc/sendmail.fc or consider replacing it with IDA sendmail. You could also try moving it to the end of /etc/rc.local. 29) What is the dump parameters for an exabyte 8200 or 8500? 8200 -- dump 0budfs 126 54000 /dev/rst0 6000 8500 -- dump 0budfs 126 54000 /dev/rst0 12000 30) What are the guidelines for setting up swap space ? This question under construction. 31) What are the general guidelines for maxusers to be set to on machine X? This question under construction. 32) What does "zsN: silo overflow" mean? The CPU serial ports - both ordinary serial ports A and B, and the port for the keyboard and mouse - use the Zilog Z8530 SCC chip. That chip has a 3-character on-board buffer called the "silo". If a character arrives in the silo, the chip interrupts the CPU at a high priority, and the interrupt service routine reads the character out of the silo. If the interrupt isn't serviced in time, more than 3 characters can be placed in the silo by the chip; if so, the chip notes that the silo "overflowed", and the interrupt service routine, when called, will note that a "silo overflow" occurred. If the machine is printing a message from the kernel, interrupts from the chip will be held off; if the message takes long enough to print, and characters are coming in quickly enough on the serial port, more than 3 can arrive, and a "silo overflow" will occur. It is possible that a machine that's sufficiently busy in other code that runs with interrupts held off could get a silo overflow as well. 33) What does the "N" in "zsN: silo overflow", and other "zsN" messages, signify? The name "zsN" is ambiguous. In kernel "config" files, and in the boot-time autoconfig messages, "zs0" is the first on-board Z8530 chip, the two channels of which handle "ttya" and "ttyb", respectively, and "zs1" is the second on-board Z8530 chip, the two channels of which handle the keyboard and mouse ports, respectively. In "zsN: silo overflow" messages and the like: "zs0" is the A channel on the first on-board Z8530, handling "ttya"; "zs1" is the B channel on the first on-board Z8530, handling "ttyb"; "zs2" is the A channel on the second on-board Z8530, handling the keyboard; "zs3" is the B channel on the second on-board Z8530, handling the mouse. So a "zs0: silo overflow" error is for "ttya", and a "zs1: silo overflow" error is for "ttyb", not for the keyboard or mouse. Keyboard silo overflows are "zs2: silo overflow"; mouse silo overflows are "zs3: silo overflow". 34) How do I set up a Sun serial port both for dial-in and dial-out? You need to read Chapter 11 in the "Systems and Network Administration" manual. 35) I can't get my Sun, running SunOS 4.1[.x], to establish a UUCP connection to some non-Sun machine; it won't log in. What's wrong? The 4.1[.x] UUCP normally runs in even-parity mode when logging into another machine. If the other machine is running in 8 bits, no parity, mode, the fact that the 8th bit is set on some of the characters the Sun is sending to it will confuse it. The Sun can be made to turn the 8th bit off by putting P_ZERO in the appropriate place in the appropriate UUCP configuration file [I may have been the one to put P_ZERO there, but I forget the details; it's in the send-expect sequence in the Systems file entry for the machine, and I think you have an "expect" string of "" - i.e., "expect nothing" - and a "send" string of P_ZERO - i.e., make the parity bit zero. Check the UUCP stuff in the "Systems and Network Administration" document to make sure.] 36) Do the Sun serial ports support RTS/CTS flow control? The serial port hardware can do CTS-based control of the flow of data *from* the Sun *out* the serial port automatically. The tty driver option for that is the CRTSCTS option; it can be specified in: the "printcap" "ms" capability for a printer; in the "gettytab" "ms", "m0", "m1", or "m2" capabilities for a dial-in port; the "STTY=" option for a dial-out line for UUCP or "cu" [check the UUCP documentation for details]; and can be specified with the "hf" capability in "/etc/remote" for "tip". The hardware cannot directly do RTS-based control of the flow of data *into* the Sun, and the software does not currently support controlling the flow of data into the Sun with RTS. NOTE: the EEPROM options in newer Suns do not affect the flow control performed by the OS; in fact, the OS ignores the "ttya-mode", "ttyb-mode", "ttya-rts-dtr-off", and "ttyb-rts-dtr-off" EEPROM options entirely. You don't need to set them to change the way the OS handles the tty, and even if you do set them, it won't change the way the OS handles the tty. 37) How do I specify that a serial port should, or should not, ignore the state of the Carrier Detect line? Prior to SunOS 4.1, you do so either by: changing the "flags" field for the serial port device in the kernel "config" file, re-running "config", rebuilding the kernel, and rebooting with the new kernel; or, on the Sun-4c machines: changing the setting of the "ttya-ignore-cd" or "ttyb-ignore-cd" EEPROM settings if the port is one of the CPU serial ports. In SunOS 4.1 (and, I think, some SunOS 4.0[.x] releases for the Sun386i), you do so by changing the "/etc/ttytab" line for the port in question to have the "local" attribute if CD is to be ignored, or not to have it if CD is not to be ignored, and running the "ttysoftcar" command to tell the kernel that the status of the "ignore CD" flag should be changed. In 4.1, there's no need to change the EEPROM setting to change SunOS's behavior; it may affect the PROM's behavior, but that's the only reason why it'd be necessary. 38) I put in a new "termcap" entry, or updated an existing "termcap" entry, for a terminal, but "vi" doesn't seem to know about my change. Why? The "vi" in SunOS 4.1[.x] is based on the System V Release 3.1 "vi", because that version of "vi" supports 8-bit character sets. That version of "vi" uses "terminfo", not "termcap"; you have to change the "terminfo" entry for the terminal. You may first have to convert the compiled "terminfo" entry to a text entry; "/usr/5bin/infocmp -I <terminal-type>" will write the text of the "terminfo" entry for the terminal <terminal-type> to its standard output. If you already have a "termcap" entry, you can convert it to a "terminfo" entry with "/usr/5bin/captoinfo". A text "terminfo" entry must be recompiled in order for programs using "terminfo" to use it; "/usr/5bin/tic" will recompile it. 39) I have a Type 5 keyboard, and find its placement of the Caps Lock, Control, and Esc keys inconvenient. How do I remedy this? Well, one remedy may be to buy the "UNIX layout" version of the Type 5; this option seems, unfortunately, to be little-known to Sun customers, and Sun may not be promoting it as they should. That keyboard has a layout much more friendly to the traditional UNIX user than do the normal PC-style layouts for the Type 5. If you don't have that option, you can use the appropriate program to reprogram the keys; see the next question. 40) How can I move keys around on a Sun keyboard, for example exchanging the Caps Lock and Control keys on a Type 5 keyboard? It depends on which window system you're running, if any. If you're not using any window system, or you're using a window system such as SunView that uses the OS's keyboard event translation mechanism, you can dump the tables used by the OS's keyboard event translation mechanism with the "dumpkeys" command, and load changes to that table with the "loadkeys" command; see LOADKEYS(1). If you're using X11 - either in its MIT incarnation, or Sun's Open Windows incarnation - or some other window system that shuts off the OS's keyboard event translation mechanism, you need to use the window system's commands, if any, for that function. In X11, the command for that is "xmodmap"; its translation tables can be printed with "xmodmap -pk", and changes to that table can be loaded with "xmodmap" as well. NOTE: in the particular case of the Control and Caps Lock keys, while MIT X appears to handle interchanging those two keys correctly, so that the new Caps Lock key is a toggle and the new Control key is not, some versions of Open Windows do not - even though the keys have had their mappings exchanged, the window system server still thinks that the *old* Caps Lock key, which is now the Control key, should be a toggle, and that the *old* Control key, which is now the Caps Lock key, should not be a toggle. 41) My Sun doesn't have an ANSI C compiler. How can I get one? SunOS releases prior to 5.0 come with a C compiler; however, it's an old compiler, and doesn't support ANSI C syntax or such ANSI C features as function prototypes. Many vendors offer ANSI C compilers for SunOS. Sun sells Sun C 1.1 for SPARC, which includes an ANSI C compiler (although not a full ANSI C environment, i.e. it doesn't necessarily include all the ANSI C include files or library routines); various other vendors (Lucid? Others?) sell ANSI C compilers as well. The Free Software Foundation's GCC also supports ANSI C syntax and ANSI C features; it can be FTP'ed in source form from many sites, and in binary form from some sites. [Sorry, I don't have details.] SunOS 5.0 - the OS component of Solaris 2.0 - doesn't come with a C compiler of any sort (NOTE: it isn't necessary for kernel configuration). If you want a C compiler for it, you'll have to buy or otherwise obtain one; Sun has or will have one for SunOS 5.0, and a version of GCC for Solaris 2.0 is also available. The include files and libraries in SunOS 5.0 should (modulo bugs) fully support ANSI C. A compiled version of GCC for SunOS 5.0 is avaliable from ftp.uu.net in the /systems/sun/gnu-solaris directory. 42) How do I change the time zone setting on my machine? In releases prior to SunOS 4.0, you will have to reconfigure your kernel, recompile it, install the new kernel, and reboot. See the documentation on kernel configuration. In SunOS 4.0 and later releases, you will need to run the "zic" command with the "-l" flag, with the appropriate time zone setting as the argument. For example, to set the time zone to US Eastern Time, do: zic -l US/Eastern to set it to the proper setting for Great Britain and Eire, do: zic -l GB-Eire and so on. You will then probably want to reboot your machine, in order to: 1) cause any daemons started before the time zone was changed to restart, and pick up the new time zone; 2) run "tzsetup" for the benefit of old pre-SunOS 4.0 binaries, old programs not converted to use the new routines to convert local time to UNIX time, and Calendar Manager. You can also manually link "/usr/share/lib/zoneinfo/localtime" to the appropriate time zone file, but there's really no point in doing so when "zic -l" will do that for you. 43) I'm getting messages that say (one of): proc: table is full file: table is full dquot: table is full inode: table is full What does this mean, and how do I fix the situation? In SunOS releases prior to 5.0, many tables in the system are allocated once at system startup time, with a fixed size, and do not grow in size. If the system needs more entries than are present in that table to perform some operation, it can't perform the operation, and it will log a message and return a failure indication. The sizes of the tables in question are based on the "maxusers" value in the configuration file for your kernel; to increase the size of the table, change the configuration file for your kernel to have a larger "maxusers" value, re-run "config" on that file, rebuild the kernel, install the new kernel, and reboot. SunOS 4.1 and later shouldn't get "inode: table is full", as that table is dynamically allocated; SunOS 5.0 should dynamically allocate entries in most if not all of those tables. I did that, and I'm still getting that message. What do I do now? Presumably, then, either: 1) you didn't increase "maxusers" enough or 2) some process is consuming resources from the table in question without bound. Note: SunOS kernels(up to 4.1.3) by default allow the user to use all available process slots(except for the last 5). If you are running out of process slots you may want to change the kernel parameter that controls the maximum number of per user processes. You can change this in the param.c in /sys/conf.common. You will need to change the following define: #define MAXUPRC (NPROC - 5) to something more reansable like #define MAXUPRC (NPROC - 5)/2 After making this change you should re-config and re-build your kernel. The "proc" table has one entry for every process on the system; if it's overflowing, some process on the system may be creating new processes over and over again. If you can, do a "ps -ax" to see what processes are on the system, and see if that gives any clues as to what process, if any, is spawning those other processes. The "file" table has one entry for every "active file descriptor" on the system; each time an "open", "dup", "socket", etc. call is made, a new "active file descriptor" is required. There's no way of finding out what process or processes are consuming file descriptors that's as convenient as "ps" can be for finding out what process or processes are spawning additional processes; "/usr/etc/pstat -f" will print the "open file table" of "active file descriptors", but it's tricky for the novice user, programmer, or administrator to interpret the output of "pstat -f", and that output doesn't indicate which processes are using a given "active file descriptor". 44) How do I run both OpenWindows and MIT X11R5? To get X11R5(or R4) applications to run under Openwindows you will need to set the appropriate LD_LIBRARY_PATH. Assuming you installed 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 environment set path = (/usr/bin/X11 $path) setenv LD_LIBRARY_PATH /usr/lib OpenWindows set path = (/usr/openwin/bin /usr/openwin/demo $path) setenv LD_LIBRARY_PATH /usr/openwin/lib You can also run clients from one environment under a different server on a one command at a time basis. This example runs a OpenWindows client under the MIT server: (setenv LD_LIBRARY_PATH /usr/openwin/lib; x_soundtool) A better way to handle this(in the long run) is to re-compile the X server clients to include a "hard" coded shared library search path. You will need to link the clients with -L option. For example, if your X11 libraries are installed in /usr/local/lib/X11 you will link your application by cc -o app app.c -L/usr/local/lib/X11 -lX11 -lXext By doing this to all applications you can eliminate the need to set the LD_LIBRARY_PATH. For applications that you do not have source for you should write a shell script wrapper similar to the following: #!/bin/sh LD_LIBRARY_PATH=/usr/local/lib/X11; export LD_LIBRARY_PATH /usr/local/bin/X11/xterm.bin $* Note: Source code for the Xview toolkit and MIT X11R5 are available from prep.ai.mit.edu. 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, CSPreview and Ghostview, they both offer fancier preview capabilities. These programs are currently available via anonymous ftp: Ghostscript is on prep.ai.mit.edu (18.71.0.38) in /pub/gnu GSPreview is on export.lcs.mit.edu (18.24.0.12) in /contrib Ghostview is on prep.ai.mit.edu (128.105.2.196) in /pub/gnu 45) Where do I find a "restricted" shell for SunOS? /usr/lib/rsh is a "restricted" Bourne shell. 46) Will SunOS 4.1.x binaries run under Solaris 2.0? This question under construction. 47) When I try to compile MITs X11R4 applications under Openwindows 3.0, I get the following "undefined" symbols(_get_wmShellWidgetClass, and _get_applicationShellWidgetClass). What is the Problem? There are problems with the Xmu shared library as shipped from Sun. There are two "fixes". One is to get the Openwindows patches that apply to this problem and the other is to "statically" link the Xmu library into the executable. The patches you will need are as follows: Patch i.d. Bug i.d.'s O/S Description ---------- ------------------------------------------------------- 100512-02 1086793 1086912 4.1.x OpenWindows 3.0 libXt 1074766 Jumbo patch 100573-03 1087332 4.1.x OpenWindows 3.0 undefined symbols when using shared libXmu. To "statically" link your executable with libXmu modify the compile line as follows: -Bstatic -lXmu -lBdynamic 48) What is Solaris? Solaris consists of the following facilities: 1) SunOS 2) Openwindows 3) Openwindows deskset tools 4) ONC networking products and services(which includes NFS and NIS) Solaris is not an operating system but a "complete" user environment. 49) What does the "nres_gethostbyaddr !=" error mean? This message is from "ypserv" and has been determined to be "harmless" (bug #1039839). Sun supplied a patch 100141-01 to quiet it, but the patched version appears to die silently at random times, so Sun now has a new patch, 100141-02. This message can be generated because the Domain Name Server lacks a reverse map entry for that particular host. 50) How come my mouse only works in the vertical(or horizontal) direction, how do I repair it? One of the LEDs on the under side of the mouse has probably "burnt" out. You can probably repair it yourself(if you can get a replacement LED and you know how to use a Soldiering Iron) by following a set of directions available from thor.ece.uc.edu. Get the file /pub/sun-faq/mouse.fix. Finally, you should try turning your mouse pad 90 degrees and see if that corrects the problem. Note: Also, 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. 51) What do the following undefined symbols mean(dlopen, and dlclose)? If you have just installed a new shared library under 4.1.2 or greater you need to modify the Makefile for the shared libraries and re-install. You will need to change the following line ld -assert pure-text `${OBJSORT} lorder-sparc tmp` to read ld -assert pure-text `${OBJSORT} lorder-sparc tmp` -ldl Note: You should change both such lines. If you are trying to run a 4.1.2 or greater executable on machine running 4.1.1 or earlier you will need to copy /usr/lib/libdl.so.1.0 off a 4.1.2 machine and install in /usr/lib on the 4.1.1 machine. Note: These symbols can be found in libdl.so.1.0 under 4.1.2 or greater machines. 52) What does "No network locking on host" mean after upgrading to Solaris 2.0? Your SunOS 4.x(or above) machines are running an old version of rpc.lockd. You need to get and install patch number 100075-09 to correct this problem. 53) Does Password Aging work with NIS(YP) ? Password aging will only work under SunOS 5.0 with NIS+. Sun does not support password aging under NIS(OS version to 4.1.3). The rpc.yppasswdd needs to modified to make password aging work. 54) What does "rpc.lockd: Cannot contact status monitor!" mean? For some reason rpc.lockd can not talk to rpc.statd. Check to see if rpc.statd is running. If rpc.statd is not running re-start it. If rpc.statd is running, kill it and restart it. To get rpc.statd to re-start you may need to remove the /etc/sm and /etc/sm.bak directories. 55) How do I join the Sun User Group(SUG)? Here is the information on joining SUG. Sun User Group, Inc. 1330 Beacon Street, Suite 315 Brookline, MA 02146 USA voice: +1 617 232-0514 fax: +1 617 232-1347 office@sug.org With your membership you get the following: * Vendor Discounts * Technical Conferences * Software Distribution * README Newsletter * Annual Exhibits * Local User Group Support * Newsgroup comp.org.sug 56) How do I increase the number of "pseudo" terminals(ptys) ? To add more ptys you must install a new kernel. The default number of "ptys" is 48. To get more "ptys" change the kernel config line "pseudo-device pty" to "pseudo-device pty#" where '#" is the number of "ptys" you want. Be warned the maximum number you can have is 255(don't use 256, this wraps to 0) -- Rob Montjoy - Rob.Montjoy@UC.Edu Computer Engineer - montjoy@ucbeh.BITNET University of Cincinnati - montjoy@babbage.ece.uc.edu Electrical and Computer Engineering - uunet!uceng!rmontjoy -- To Save the Earth.
