PROBLEM:  I am receiving a trap, interrupt or exception message and don't
           know what it means.

PROBLEM:  Commands such as who(C), finger(C), and ps(C) may show established
          telnet sessions when the client end of the TCP connection no longer
          exists, as, for example, when the client computer crashes, or is
          powered off or reset without first closing the telnet session.
          Established sessions may also be shown when network connectivity
          to the client has failed.

PROBLEM:  The maximum file length supported by VXFS filesystems on UnixWare 7
          systems is 1 terabyte. How do I enable this support on a VXFS
          filesystem?

PROBLEM:  I am experiencing one or more of these network printing problems on
          UnixWare 7:

          1. Spooling a job using the lp command to a remote bsd printer can
             return the following message:

                UX:lp: ERROR: No space to allocate temp files.
                UX:lp: TO FIX: Clean up disk, or try again later.

          2. Under heavy load, lpsched can core dump (lpNet remains).

          3. lpsched can core dump when executing the lp command to print
             many files with very long filenames.

          4. 'lpsched' in ptf7438a fails to link on u701 and u700.

          5. 'lpsched' suddenly stops printing the remote printer requests.

          6. If a user cancels a job, lpsched sees the lpNet as busy and
             never sends the cancel job. The job will be shown as canceled
             (lpstat), but will not be removed.

PROBLEM:  PCI devices of class 'bridge' are not handled correctly and are not
          recognized.  The device may appear in the DCU but without entries for
          IOADDR or MEMADDR.

          The device class 'bridge' was recognized properly in UnixWare 7.1.0.

          A panic occurs related to use of hot plug features.

          SCO OpenServer 5.0.4 media, you may get this error when trying
          to access SCOadmin utilities.

          before performing kmem_free() on the vx_bignode.

PROBLEM:  The FTP daemon, /usr/sbin/ftpd (based on WU-FTPD), has a security
          vulnerability that can allow unprivileged users to obtain root
          access through use of the "site exec" command. This vulnerability
          is described in CERT advisory CA-2000-13 (see http://www.cert.org).

PROBLEM:  I am experiencing the following problems with the UnixWare 7.1.1
          Network Install Server:

          1. When disabling the Network Install Server from the command line
          using:

              # /usr/sbin/installsrv -d

          the following error message appears:

PROBLEM:  When I select the:

              Actions -> Disable

          option in the Install_Server GUI on UnixWare 7.1.1, the Network
          Install service is not disabled. The script attempts to load the
          UnixWare package instead.

          Does this SSE address the security problems described in CERT

PROBLEM:  I am installing UnixWare 7.1.1 and my Support representative has
          asked me if I am installing from the updated 7.1.1 Media Kit (which
          was released in September 2000) or the previous 7.1.1 Media Kit.
          Which one do I have?

PROBLEM:  A network card has suffered a connection failure on one of the nodes
          in a NonStop Cluster; new network connections have successfully
          been accepted, as the surviving network cards in the nodes across
          the cluster continue to service the Cluster Virtual IP (CVIP)
          address.

          However, the failed NIC connection issue has now been resolved
          (NIC cable was pulled out and has now been reconnected) but the NIC
          still fails to accept new connections and service the CVIP.

PROBLEM:  UnixWare 7 NonStop Clusters (NSC) Release 7.1.1+IP has been
          installed and a dependent node is being set up.

          If the NSC license is entered after installation of the NSC software
          then the license may be reported in the license manager as:

             0 additional CPUs

          instead of recognizing the license as "NonStop Clusters 3-6 node
          bump" or "NonStop Clusters Extensible two-node license". The license
          manager also prompts for the node number to add the license to, when
          in fact the license should be clusterwide and no node number prompted
          for.

          If the license is entered during the dependent node installation
          process, then the following message may be seen:

    NSCinstall: WARNING: No NonStop Clusters (NSC) licenses have been installed.
    A 2-Node NSC License must be added before this node can join the cluster.
    Do you want to use a 2-node NSC Trial License (default:y) [yes,no,?]

          And subsequently:

    nsclicense: WARNING: NSC Clustering is installed but no NSC licenses have
    been added.  A two-node NSC license must be added before other nodes can
    join the cluster.
    Do you want to use a 2-node NSC Trial License (default:y) [yes,no,?]

          If the trial license is not used, then on boot the message above
          may be seen, followed by this message:

    UX: init: INFO: Cluster formed: 1 2
    UX: init: ERROR: The NSC cluster boot is being aborted because it involves
    more clusternodes (2) than there are NSC licenses (1).  Please bring up a
    single node and check/correct the status of the NSC licenses.

          And both nodes will be shut down.

          While this problem is in effect it will only be possible to boot
          the root node.
