DEFAULT Program
different security. For more information about changing the default values and
about disk file security, see the Guardian User’s Guide.
•
Any new logon default values you set with the DEFAULT program do not take
effect until the next time you log on or until you enter the VOLUME command with
no parameters.
•
The current default settings are often different from your saved logon default
settings. When you log on, your logon default settings are in effect for system (if
you are on a network), volume, subvolume, and file security. After you log on, you
can change the current default volume or system with the VOLUME or SYSTEM
command. Neither of these commands, however, affects your logon default
settings. Every time you log on or enter a VOLUME or SYSTEM command with no
parameters, your logon default settings are restored. If you have changed these
settings with the DEFAULT program, the new values are in effect. For more
information, see the descriptions of the VOLUME Command on page 8-259, and
SYSTEM Command on page 8-224.
•
The TACL process creates a root segment, even if the default volume doesn't
exist. Users can logon even if the default volume doesn't exist.
•
Avoid specifying your current local system as the default system: Doing so is
unnecessary, and can in fact cause problems with some programs.
•
You cannot use the security specifier “-” (allow access to local super ID only) with
the DEFAULT program.
•
When a new user is added, the logon defaults are:
°
Volume $SYSTEM
°
Subvolume NOSUBVOL
°
Security “AAAA”
Example
Assume that you want your logon default volume to be $BIG, and your logon default
subvolume to be BAD. You also want your logon default disk file security to:
•
Allow any user on any system to read and execute a file with your default security
•
Allow only you, the owner of a file, to write to and purge a file with the default
security. (In addition, you must be logged onto the system where the file resides to
be able to write to such a file or to purge it.)
To set these defaults, enter:
14> DEFAULT $BIG.BAD, "NONO"
THE DEFAULT sys-vol-svol HAS BEEN CHANGED TO $BIG.BAD
THE DEFAULT file-security HAS BEEN CHANGED TO "NONO".
To put these new logon defaults into effect, you must either log on again or enter:
15> VOLUME
