NAME [Toc] [Back]
hostvar - A dcecp task object that manages the security binary
compatibility attributes
SYNOPSIS [Toc] [Back]
hostvar help [operation | -verbose]
hostvar operations
hostvar set -secbinarycompat {on | off}
hostvar show {-all | [-cellname] [-hostname] [-secbinarycompat]}
ARGUMENTS [Toc] [Back]
The name of the hostvar operation for which to display help
information.
DESCRIPTION [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 operation
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.ft3 set Sets the value of the
specified host variable. show Returns the value of the
specified host variable. help Prints a summary of
command-line options. operations Returns a list of the valid
operations 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.ft3 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.ft3 dcecp> acl modify hostdata
-change {user hosts/hostname/self cdprw} -io -local.ft3 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
setting 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.ft3 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
command 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.ft3 {cellname /.../gumby1} {hostname
hosts/blech} {secbinarycompat on} dcecp>
