The following problems are addressed in Technical Articles that appeared on
SCO's site on 960320.

Some of these TAs are new, others are revisions of prior versions.

PROBLEM:  What is the SCO DCE Development System for SCO OpenServer 5,
          Maintenance Supplement 107, and how do I install it?

PROBLEM:  I configured a system to use NIS, but I don't want to run it
          anymore.  Now, I can't change the password for a local user.  
          If I stop nis and try to change the user's password, I get these
          error messages:

             yppasswd: can't get master for passwd file

             Password request denied.
             Reason: Remote password change request denied.

          Similar problems occur when trying to add a new user to the system.

PROBLEM:  Are the 3Com EtherLink III PCI cards supported?

PROBLEM:  When my system boots, I get the error:

 dynamic linker: /etc/devnm:  Cannot open /dev/zero for file /lib/  

          I may also see the error:

              su: 23 Killed


              su: /dev/null: cannot create  

          This message also appears when users try to log in and they
          are returned to the login prompt.  The user 'root' is able to
          log in without a problem.  The bourne shell may work, while
          C shell and Korn shell do not.

PROBLEM:  When I run:

            # fontserv start

          I get the error message:

            TCP/IP must be running before starting the font server.

PROBLEM:  What is the support status of Tricord machines?

PROBLEM:  I have configured a number of SCSI tapes using the mkdev(ADM)
          command.  When I relink the kernel, this message is displayed:

                idmkreg : error updating space.c for Stp

          I have tried removing all of the tape devices, again using
          mkdev(ADM).  When I viewed the current SCSI tape configuration
          using this utility, it indicated that there were no longer any
          SCSI tape devices configured.  However, this did not prevent
          the error message from being reported when I once again tried
          to relink the kernel.

PROBLEM:  When I run:

            # timedc clockdiff sunbox

          where "sunbox" is a SUN Solaris 2.3 or SUN Solaris 2.4 system,
          I get this error message:

            sunbox is down

          I am sure sunbox is running, as it responds to other requests
          from the net.

PROBLEM:  I am trying to install SCO OpenServer Release 5.0.0 on my system
          and I am using the "Interactive fdisk/divvy" option of the
          Installation Query Manager (IQM).  From within fdisk(ADM) I have
          set up an active Unix partition, but when I exit from fdisk(ADM)
          using the 'q' option, I get the error message:

                Can't read bad track table: No such device or address

                Please repartition your disk, creating the active
                Unix partition after the bad area on the disk.

                The hard disk installation program will now invoke /etc/fdisk
                Entering 'q' at the following menu will exit /etc/fdisk
                and the hard disk installation will continue.

                If you wish to exit press the <DEL> key.

          I am returned back to the fdisk(ADM) menu.  Pressing the <Del>
          key does not help.

PROBLEM:  What Adaptec 1510 or 1520 chipsets work with the "spad" driver ?

PROBLEM:  I have attached an HP JetDirect printer to one of my networks
          and configured it on my UnixWare box as remote BSD Unix printer.
          When I print to it, there is often a delay of two minutes before
          the job gets printed.  If I have more than one file to print,
          there is always a delay of two minutes between print jobs.

PROBLEM:  The SCO UnixWare product is based on SCO UNIX System V/386
          Release 3.2 Operating System Version 4.2, the design and
          implementation of which differs in some respects to other
          SCO UNIX products.

          Are there books available which cover the particular implementation
          used for the UnixWare product?

          Is there an equivalent to the 'Bach' book, "The design of the UNIX
          Operating System" for SCO UnixWare?

PROBLEM:  By default, UnixWare does not allow ftp(TC) login as
          the 'root' user.

          If I attempt to use the 'ftp' utility to transfer files to
          or from my UnixWare system, I can't log in as the root user.
          For example, when I invoke the 'ftp' command on the UnixWare
          host 'aberavon' to another UnixWare system with a hostname
          of 'bangor', I get this message:

                $ftp bangor
                Connected to bangor
                220 BANGOR FTP server (UnixWare 2.01) ready.
                Name (bangor:owner): root
                530 User root access denied
                UX:ftp Error: Login failed

PROBLEM:  How can I find out what release version of UnixWare I am

PROBLEM:  I have set up my system to allow specific devices to be
          allocated using the assign(C) command.

          If I run the command without arguments, I get this output:

                fd0  FREE

          If I run the command a second time, I get the error:

                Memory fault - core dumped

PROBLEM:  Can the manufacturer and model of SCSI devices be determined using
          software, for example, to assist in a hardware audit?

PROBLEM:  When I attempt to use removepkg(ADM) to remove a product
          that was installed using installpkg, the following occurs:

          1. The correct product is recognized as one that can be removed
             using removepkg(ADM).

          2. I can select the product for removal.

          3. I am requested to insert the removable media.

          4. After inserting the removable media, I get an error
             message notifying me that the media type of the install
             media cannot be determined.

           5. I am then cycled back to the prompt to insert the
              install media.  

          The product I am attempting to remove is not removed.

PROBLEM:  I have had a system crash and I need to reinstall my root filesystem
          from backup.  I am following the instructions in the Troubleshooting
          Reference Chapter of the System Administrator's Guide, but the
          instructions do not produce the expected results.

PROBLEM:  What industry standards does SCO UnixWare support?

PROBLEM:  I am running SCO OpenServer Release 5.0.0 with SCO SMP (Symmetrical
          Multiprocessing) Release 5.0.0 on a Corollary Architecture machine
          and the following message is displayed on the console:

                WARNING: IP:spinning on PCB:<address>

          This only happens on systems where networking is in use.

PROBLEM:  Just after the filesystem has been made, my installation of SCO
          OpenServer Release 5.0.0 fails with the error:

                "Exit value 1, Status value 256".

PROBLEM:  After choosing the boot option from the Virtual Disk Manager Menu
          bar, choosing either 'Mirror Root...' or 'Mirror Swap...' causes
          this error message to occur:              

            Cannot determine the physical device vdisk15 resides on

          The operation is terminated.

PROBLEM:  I want to set up and use all three ports of an HP JetDirect
          EX Plus3 print server and I can only get the first port to work.

PROBLEM:  I installed UnixWare on my computer but I didn't have any COM ports.
          I have now installed COM ports, and used sysadm to configure them,
          but the UnixWare operating system still doesn't see the ports.

PROBLEM:  I installed UnixWare on my computer but I didn't have any COM ports.
          I have now installed COM ports and used sysadm to configure them but
          the UnixWare operating system still doesn't see the ports.

PROBLEM:  In previous releases of SCO operating systems, you could print
          and then modify or remove the original file and still get the
          printout of the original file.  In SCO OpenServer 5.0, if you
          modify the original file, the printout may be of the modified file.
          If you remove the original file, you may get a printout of this

          cat: cannot open /path/filename: No such file or directory (error 2)

PROBLEM:  When DOS formats a disk, it puts a DOS filesystem on it
          using 33 512-byte blocks and leaving 1,457,664 bytes total
          disk space.  Some of the disk images on SCO's Online Support
          (SOS) system are a full 2880 512 -yte blocks, or 1,474,560 bytes.
          I can't copy these to a DOS diskette to move it to my UNIX

PROBLEM:  How do I configure a RAID 5 array using the Virtual Disk Manager?

          RAID 5 is based on data striping (as in RAID 0) and parity
          (as in RAID 4).  Data striping distributes data blocks across
          pieces stored on multiple disks.  The difference between
          RAID 5 and RAID 4 is that parity is striped across all disks.
          Because parity information is distributed, no one disk bears an
          excessive I/O load.  Thus, RAID 5 is preferred to RAID 4. Parity
          is defined as redundancy (or error-correction) information
          generated during writes.  If a disk in the array fails, the
          parity information and the partial data on the remaining disks
          are used to reconstruct the data.  It requires a minimum of three
          pieces on separate disks. You should not create three pieces on
          one disk, as disk failure would disallow any method to rebuild
          it with RAID 5.  

          The following example assumes three 540 megabyte SCSI disks
          are attached to one SCSI host adapter.  None are part of the root
          or bootable hard drive, and the entire disk space for each of
          the drives will be used in the RAID 5 array.

PROBLEM:  While using "mkdev tape" to configure the system for a SCSI tape
          attached to a Compaq SCSI Integrated SCSI-2 Options port host
          adapter (which is supported by the CUCCS driver), I get this
          error when doing the kernel relink:

undefined                       first referenced
 symbol                             in file
PROBLEM:  When trying to telnet into a UnixWare system as root,
          I get this message:

                  UX:in.login: ERROR: Not on system console
                  telnetd: Unable to invoke login scheme.
                  Connection closed by foreign host.

PROBLEM:  My machine was successfully installed and I can bring the desktop
          up, but I am unable to launch clients from it.  Clicking on an
          icon causes the clock cursor to replace the arrow cursor. The
          process then either hangs, or comes back to an arrow cursor, without
          starting the client program. I am using a monochrome display.

PROBLEM:  After typing <Ctrl>D to enter multiuser mode, the system hangs
          on the way up to multiuser mode.

PROBLEM:  After typing "shutdown -g0 -y" my system hangs and I never
          see the safe to power off prompt.

PROBLEM:  I've installed my machine successfully and now I need to know
          about configuring the machine.

PROBLEM:  By default, ftpd writes to /var/adm/log/osmlog. I want to redirect
          the output of ftpd to a file of my choosing.

PROBLEM:  I did something wrong in configuring my console, and when the system
          boots, the desktop isn't readable.  I can't get into the system to
          change the configuration.

PROBLEM:  I get the following message on my screen:

          "WARNING: NLM: RPC call failed: RPC error: xxxxxx, errno 0"

          where 'xxxxxx' could be one of the following:

                  rpc_mount failed

          Note: This is not a fatal error, but only a warning.  The
          message is generated when nfs is started and the "lockd"
          command is invoked, which occurs in the startup or shutdown
          rc scripts, or if nfs is started manually.

PROBLEM:  I have an Adaptec 3940 Dual Channel SCSI PCI controller and want
          to use it for SCO OpenServer Release 5.

          I have attempted to configure this adapter to use the "alad" driver.
          When SCO OpenServer 5 is booted up, these driver messages are seen
          on the hardware screen:

                device    address       vector  dma     comment
                %adapter  0xXXXX-0xXXXX 11      -   type=alad ha=0 id=7 fts=st
                %adapter  0xXXXX-0xXXXX 11      -   type=alad ha=1 id=7 fts=st

          Although the devices on channel A work fine, I cannot access any of
          the devices on channel B.

          I have tried three different alad drivers:

              - the one supplied in the basic SCO OpenServer 5 product
              - the one from the Advanced Hardware Supplement 5.1
              - the one supplied in the Adaptec package ("alad325")

          The symptoms of this problem are, however, the same when using each
          of these drivers.

PROBLEM:  I have an existing CGI application which runs without any problem
          on SCO UNIX System V/386 Release 3.2 Operating System Version 4.2.
          However, when I attempt to run this same program on SCO OpenServer
          Release 5 (with Release Supplement 5.0.0d applied), this same
          application hangs.

PROBLEM:  I get the following message when I boot my SCO OpenServer 5.0.0
          system into multiuser mode:

             Calendar server is executing...
             Error: Incorrect SCO ISAM Runtime System installed: 0
             Error: Incorrect SCO ISAM Runtime System installed: 0

PROBLEM:  Has the Compaq 5100 notebook computer been certified for use
          with SCO OpenServer Release 5.0.0?

PROBLEM:  In UnixWare 1.x, I could position the mouse over the DOS icon,
          press the right mouse button, and select Options from the pop
          up window.  In Options, I could select LPT PORT and attach my
          DOS printer to a Unix device and not use the Unix spooler.  
          I can't do this in UnixWare 2.x.

PROBLEM:  I am developing software, which by means of using inetd(ADMN),
          waits for an incoming connection from an X.25 network (for example)
          and creates a login session on SCO OpenServer 5.

          My software worked fine on previous SCO operating system releases
          (Version 4.2-based and earlier). However, on SCO OpenServer
          Release 5, although the login is successfully performed and a
          shell is started, the logname(C) utility fails with this error

                could not find entry in /etc/utmp

          However, if I use the SCO UNIX Operating System Version 4.2 version
          of logname(C) on this SCO OpenServer 5 system, this older utility
          does work correctly.

          Has logname(C) changed in SCO OpenServer Release 5?

PROBLEM:  I logged into SCO OpenServer Release 5 as the user "user1" and
          then executed su(C) to another user, "user2".  However, when I
          execute the command "who am i" or "who -m" (see who(C)), this
          command returns no value.  In previous versions of SCO UNIX,
          "who am i" returned the original login user name, for example:

          (Note that "sco_OSr5" refers to an SCO OpenServer 5 system and
          "sco_OSr3" refers to an SCO Open Desktop 3.0 system.)

          Log in as "user1" on the system "sco_OSr5":

                sco_OSr5# who am i
                user1      ttyp0        Feb 28 07:02
                sco_OSr5# su - user2
                sco_OSr5# who am i

          Log in as "user1" on the system "sco_OSr3":

                sco_OSr3# who am i
                user1      ttyp0        Feb 28 07:10
                sco_OSr3# su - user2
                sco_OSr3# who am i
                user1      ttyp0        Feb 28 07:10

PROBLEM:  I want to install some software from a non-standard tape or CD-ROM
          device using the Software Manager (custom(ADM)) but I cannot find
          a way to get the Software Manager to see my device.

PROBLEM:  I want to enter single user mode (init state s) from a cold boot,
          but when I turn on the computer, it never prompts me with this

PROBLEM:  How do I get information about licensing for an SCO UnixWare

          I am used to accessing this information via the uname(C) command,
          but the relevant fields returned by "uname -X" are all blank.

          Specifically, how do I get the serial numbers and activation key
          numbers that have been installed on a system?

          How do I get information for the number of CPUs and users
          licensed for a system?

PROBLEM:  I am trying to install a new package with the "pkgadd" utility.
          The installation fails with a message similar to:

                      bad entry read from contents file
                      -pathname /usr/include?sac.h
                      -problem: unable to read class token
                      ux: error unable to merge package and system information

PROBLEM:  After installing UnixWare on my computer, my mouse has stopped
          working and I can't use the desktop.

PROBLEM:  Supplemental groups do not work when I use ftp(TC).

          For example, consider a user who ftp's to a system where the
          login used is "guest".

          "guest"'s login group is "groovy", and is also in a supplemental
          group "grunge".

          This example shows an ftp(TC) session with attempts at changing
          directories with read and execute permissions for "grunge" and

             ftp> ls
             200 PORT command successful.
             150 Opening ASCII mode data connection for /bin/ls (0 bytes).
             total 4
             drwxr-x---   2 root     grunge      32 Jan 12 15:04 denied
             drwxr-x---   2 root     groovy      32 Jan 12 15:02 ok
             226 Transfer complete.
             ftp> cd denied
             550 denied: Permission denied.
             ftp> cd ok
             250 CWD command successful.

PROBLEM:  I want to change the default time TCP/IP waits before dropping
          a connection on my SCO OpenServer 5.0.0 system.


1. New or Revised TAs on websco, 970218

The following problems are addressed in Technical Articles that appeared on
SCO's site on 970218.

Some of these TAs are new, others are revisions of prior versions.

PROBLEM:  When doing large file transfers using rcp(C) or ftp(TC), this
          error message sporadically occurs:

            Warning SMPW (iobase 0x0000fc00) possible cable fault

          (where the iobase value will depend on where the NIC is configured),
          and the networking subsystem on the server may lock up.  In some
          cases, a reboot may be necessary to clear the hang.

PROBLEM:  The Merge documentation has examples of starting DOS with cron.
          When that is attempted with DOS applications that require a
          graphical screen, or if a MicroSoft Windows application is run
          with cron, this error occurs:              

            INIT_FAIL:dos:ERROR:Could not initialize device 'stdin/stdout'
