URGENT.DOC - important information!
It is VERY important that certain files are never found by the users.
For instance, DOSGATE.EXE if executed would attempt to come up in terminal
emulation mode. This would bypass the operating system and crash the system
as far as the user was concerned! Keep this file in a place where the user
WILL NOT STUMBLE across it and DO NOT keep it in a directory specified by
'PATH'.
One simple way to protect the system is to use a third party tool call 'CED'.
It allows one to make "synonyms" to replace any command. Use it to
map all of the following commands to the supplied program 'SORRY':
DOSGATE = sorry
DEL = sorry
ERASE = sorry
SET = sorry
FORMAT = sorry
PROMPT = sorry
The following synonyms may also be created for packet radio operations:
BYE = DISC
B = DISC
QUIT = DISC
D = DISC
Some other synonyms to help the novice DOS user out:
ROOT = CD \
UP = CD ..
Some synonyms to help with other DOSGATE/DOSMAIL commands:
R = READ
L = LIST
S = SEND
H = HELP
INFO = HELP
A *SIMPLE* way to keep users from accessing drives that may not be
available:
A: = SORRY
B: = SORRY
NOTE: CED is a public domain tool that has been included here for your
convenience. There is NO CHARGE for CED. The documentation for
CED is in the file CED.DOC.
Also, it would be a good idea to set the hidden attibute on files such as
AUTOEXEC.BAT
CONFIG.SYS
and on some directories such as
MAILSYS
DOSSYS
This helps to keep users from snooping around in areas that they shouldn't.
It is not foolproof, and any user who is very familiar with DOS can get
around these mechanisms. But most users don't know DOS all that well.
You may use other names for the various directories for further protection
as long as you change all references to those directories in the appropriate
files.
