- What's New
-
- This file contains a brief listing of new features and other
- changes from PC-Vault 4.4w. If you are not already familiar with
- version 4.4w, please skip this file and read your Administrator's
- manual.
-
-
- New In PC-Vault and PC-Vault Plus Version 4.5
-
- The implementation of Maximum Floppy Boot Protection is
- completely new and uses totally different techniques from those
- used in prior versions. It will be much more secure against a
- hacker who is trying to break in. In addition, we expect it will
- be more compatible with today's variety of disks, controllers,
- and software.
-
- Substantially improved compatibility with OnTrack's Disk Manager.
-
- The number of days that passwords remain valid and the number
- different passwords required before an old password can be set to
- different values for each user. Except on XTs, use of Password
- Ageing no longer requires that PC-VAULT.EXE be resident on the
- hard drive, nor does it require the PC-VAULT/A statement in
- AUTOEXEC.BAT.
-
- You can choose what is displayed during password definition.
- Choices include the actual characters, asterisks, or nothing at
- all.
-
- All writes to the master boot record are prohibited.
-
- The administrator can prohibit users from changing the system
- date and time. Note: It is always possible for a program to
- write CMOS memory directly, but we do not know of any that do.
- In any event, the clock regression rules will cause all passwords
- to expire if the clock has regressed by more than four hours.
- (See menu item T in Select Options.)
-
- When selecting password ageing, the administrator can choose
- whether or not the administrator password will expire.
-
- HelpUser can now be used to grant either Administrator, or User 1
- access to a PC.
-
- WHO /L will display the name of the current user.
-
- WHO /E will cause an environment variable to be defined:
- PCVU=username. This is very useful in batch files. Example:
- CD \%PCVU%
-
- The number of users in addition to the administrator has been
- increased to 12.
-
-
- The LOGOFF utility has been added. Running LOGOFF will log you
- off of the computer, and give another user the opportunity to
- logon without rebooting. Simply type LOGOFF at the DOS prompt.
- After the new user logs on, the DOS prompt will re-appear. The
- default drive will be the one from which DOS was booted. The
- default directory will be the root directory.
-
- It is no longer necessary to use the special display blanking
- option with Windows and VGA.
-
- The Windows 32 bit disk driver (also known as FastDisk and
- WDCTRL) will now load and work correctly.
-
- If one of the following comments is placed in the CONFIG.SYS file
- prior to installing PC-Vault, PC-Vault will place its DEVICE
- statement on the line following the comment.
-
- REM CLEANDSK.DRV HERE
- REM CLEANDSK.DRV HERE (HIGH)
- REM CLEANDSK.DRV HERE (SPECIAL,TEXT)
-
- The second comment line will cause PC-Vault to use a DOS 5.0
- DEVICEHIGH statement. This feature makes removal and
- reinstallation of PC-Vault easier in those situations where the
- device statement should not be first, or where a special device
- statement is required by a memory manager such as QEMM. Please
- see the administrator's manual for additional information.
-
- If a virus invades your master boot record (boot sector) or it is
- otherwise trashed, PC-Vault will recognize the condition and ask
- if you would like for PC-Vault to rebuild it for you.
-
- VIOLS /L will now display the date and time of the user's last
- logon. This will alert a user that someone else knows his/her
- password and uses the computer at times when the legal user is
- away.
-
- If the administrator states that the person installing PC-Vault
- is to be the administrator (See PC-Vault /P in your manual), he
- may also require that the administrator password be entered
- before PC-Vault will install. This will prevent unauthorized
- persons from installing PC-Vault, and ensure that the installer
- knows the administrator password.
-
- See also the "New in the EXEC Program" below.
-
-
- New In PC-Vault Plus Version 4.5
-
- A new line on the Directory Access Control screen allows the
- administrator to control each user's permissions to newly created
- level 1 sub-directories between their creation and the time when
- he actually assigns permissions to them. Users may create level
-
-
-
- 1 sub-directories if and only if they have been granted write
- permission to new level 1 sub-directories.
-
- Execute access is both necessary and sufficient to execute
- programs under Windows (this is a bug fix).
-
- The log file, ACCESS.SYS, is now locked and encrypted. FLUSHLOG
- now has a /U switch which unlocks the log file. If you delete or
- rename the log file a new locked log file will be created when
- new entries need to be added. The LOG utility (LOG.EXE) will
- automatically decrypt the log.
-
- The global .EXE/.COM access control has been replaced with
- control for each root & 1st level directory. (See the PC-Vault
- Plus main menu's D option.)
-
- Directory permissions will be remembered across removal and
- subsequent re-installation. They are stored in the file
- FPERMF.INF which is not deleted when PC-Vault Plus is removed.
-
- Directory permissions changes are effective immediately. No
- re-boot is required unless total number of root and first level
- sub-directories has been increased since the last boot. In this
- case, an informative message will be displayed.
-
- Changes in file accesses to be logged are effective immediately.
-
-
-
- New in the EXEC Program
-
- Two new parameters have been added to the EXEC program. Their
- use is somewhat technical, and most users can skip the following
- description. The EXEC command line now has the form:
-
- EXEC [/R] [/Ln] [/Tn] drive:\full_path_name\prog.ext param-list
-
- The new parameters, /L and /T allow the program started by EXEC
- to execute other programs. /Tn allows a total of n programs to
- be executed, additional execution attempts will fail. The n may
- be any number from 0 (the default) through 9. This parameter is
- necessary to start Windows 3.1, for example, because it asks DOS
- to execute 2 or 3 programs (Standard or 386 modes) during its
- startup. Once started windows could execute any number of
- Windows programs, but no DOS programs since that would exceed the
- selected value of a properly chosen n.
-
- The /Ln parameter allows the program started by EXEC to execute
- another program, which may execute another program, etc. to a
- depth of n levels. Thus if EXEC /L1 started a menu program (level
- 0), the menu program could execute any number of other programs
- (all at level 1). The level 1 programs started by the menu
- program could not execute any other programs because a depth of
-
-
-
- level 2 would not be allowed. The n may be any number from 0
- (the default) through 9.
-
- You may not use both the /L and /T parameters.
-
- New in the SET-TIME Program
-
- The command SET-TIME D will return the auto LunchBreak time
- to the time selected from the PC-Vault main menu. For example,
- if you do not want automatic LunchBreak to be operative while you
- are in WordPerfect, the commands:
-
- SET-TIME 61
- WP
- SET-TIME D
-
- will disable LunchBreak, execute WordPerfect, and then return the
- auto LunchBreak time to the current default value.
