NAME

       hostvar - A dcecp task object that manages the security binary compatibility attributes

SYNOPSIS

       hostvar help [operation | -verbose]

       hostvar operations

       hostvar set -secbinarycompat {on | off}

       hostvar show {-all |  [-cellname] [-hostname] [-secbinarycompat]}

ARGUMENTS

       The name of the hostvar operation for which to display help information.

DESCRIPTION

       The  hostvar  object  allows  you  to easily set the security binary compatibility attributes for the current host and to display the local
       host's cellname, hostname, and security binary compatibility attributes that are stored by the dced in the hostdata/dce_cf.db object.

       The cell's security server uses these compatibility attributes to determine the mode and state in which the local machine is operating.

ATTRIBUTES

       The name of the cell in which the local host is registered.  The name of the local host.  The security binary compatibility attribute  that
       enables (on) and disables (off) binary compatibility for statically linked versions of DCE.

OPERATIONS

   hostvar help
       Returns help information about the hostvar task object and its operations.  The syntax is as follows: hostvar help [operation | -verbose]

       Options Displays information about the hostvar task object.

       Used  without  an argument or option, the hostvar help command returns brief information about each hostvar operation.  The optional opera-
       tion argument is the name of an operation about which you want detailed information.  Alternatively, you can use  the  -verbose	option	to
       display detailed information about the hostvar task object itself.

       Privileges Required

       No special privileges are needed to use the hostvar help command.

       Examples

       dcecp> hostvar help set		       Sets the value of the specified host variable.  show		   Returns the value of the speci-
       fied host variable.  help		Prints a summary of command-line options.  operations	       Returns a list of the valid  opera-
       tions for this command.	dcecp>

   hostvar operations
       Returns a list of the operations supported by the hostvar task object.  The syntax is as follows: hostvar operations

       The list of available operations is in alphabetical order except for help and operations, which are listed last.

       Privileges Required

       No special privileges are needed to use the hostvar operations command.

       Examples

       dcecp> hostvar operations set show help operations dcecp>

   hostvar set
       Sets the security binary compatibility value attribute for the local host.  The syntax is as follows:
	hostvar set -secbinarycompat {on | off}

       Options Sets the security binary compatibility attribute on or off.

       Under  normal circumstances, secbinarycompat is set to on when DCE is configured, which allows binary compatibility between Version 1.2 and
       Versions 1.0.3 and 1.1. Binary compatibility allows applications linked with an archived libdce to share  login	contexts  and  credentials
       without loss of data.

       To  prepare  a  host for the set operation, a number of steps need to be performed first: Verify that the dced process is running in remote
       access mode (-r), then put the DCE daemon into partial service mode by sending the  dced  process  the  correct	signal:  #  kill  -SIGUSR1
       pid_of_dced  # Invoke dcecp with the -local option: # dcecp -local dcecp> As the machine principal (usually root), modify ACLs on the local
       hostdata object to allow the self user access by using the following dcecp  acl	operations:  dcecp>  acl  modify  hostdata  -change  {user
       hosts/hostname/self  criI}  -local dcecp> acl modify hostdata -change {user hosts/hostname/self cdprw} -io -local dcecp> Put the DCE daemon
       back into full service mode with the following command: # kill -SIGUSR1 pid_of_dced #

       Now, as the machine principal, you can set the hosts security binary compatibility value.

       You can disable binary compatibility on a per-host basis to achieve minor performance gains and slightly smaller credentials files by  set-
       ting secbinarycompat to off.  If you enable binary compatibility after it has been disabled, you must stop and start all DCE daemons and if
       you are using integrated login, log out and in.	See Planning and Configuring HP DCE for more information.  This operation returns an empty
       string on success.

       Privileges Required

       No special privileges are needed to use the hostvar set command.

       Examples

       dcecp> hostvar set -secbinarycompat on dcecp>

   hostvar show
       Returns	the  values  of  the  host  attributes on the local host.  The syntax is as follows: hostvar show {-all |  [-cellname] [-hostname]
       [-secbinarycompat]}

       Options Returns the values of all attributes.  Returns the value of the cellname attribute.  Returns the value of the  hostname	attribute.
       Returns the value of the secbinarycompat attribute.

       The show operation makes it easy to view the attributes stored in the dced hostdata/dce_cf.db object.  All the values returned by this com-
       mand are from that object.  Use the -all option to display all attributes; use individual options to display individual attributes.

       Privileges Required

       No special privileges are needed to use the hostvar show command.

       Examples

       dcecp> hostvar show -all {cellname /.../gumby1} {hostname hosts/blech} {secbinarycompat on} dcecp>
