Thanks for the other warnings and hints...
The system really is not that insecure, as there was
and is the
issue of how secure a software system can be without the
encryption that is integrated into laptops today, if you have
physical access to the machine. And the only place the
exploit you pulled can happen is on the console, so if you
secured the console and the connection and the machine,
you were okay. and it was not feasible to be more secure
as in encyrpting everything back then.
Agreed - now that I'm in to it, I've found a "whole bunch" of
accounts which have no passwords and can get to a shell.
Several of them with "high privilege.... But if these acounts
were either removed or properly password protected, they
would not present the gaping hole in security that I
exploited.
Btw, Why could this exploit not happen on another port or
the dial-in line ... Are the various system accounts (BACKUP
etc.) not accessable from all the ports (I tried from PORT-1
and it worked) - Does the BREAK interrupt not work from
a dial-up line? -- Just curious as to why this "hole" would
not be accessable from a more remote terminal.
when you get a Dave account try the following Hello
world program
CREATE-FILE MYBP
ED MYBP HELLO
if the above works, you are cooking.
Well... I used CREATE-ACCOUNT to create a DAVE
account - It asked me 4-5 rather terse/cryptic questions to
which I accepted the defaults. This created an account
which I could log in to, however
CREATE-FILE advises me that I do not have sufficent
privilege to use this command!
So I decided to try from the GAMES account since it lets
me get to a TCL prompt, and does not appear to be a
privileged account.
'CREATE-FILE MYBP' results in this error message:
CREATE-FILE MYBP
[416] RANGE ERROR IN MODULO PARAMETER.
Looks like it wants a parameter of some kind - tried
'CREATE-FILE MYBP 10' and got the same result, and
don't want to try too much else without knowing what
I'm actually doing - going to see if I can pickup a PICK
book or docs .... But if you can suggest resolutions to
the above (ie: How to create an account where you can
make files, and how to actually create the file)... that
would be helpful, as I agree that a "safe" account for
experimentation would be a good idea.
On the more positive side, I believe I have successfully
created two SYSGEN tapes - they can be booted (and it
works), but I have not tried performing an actual restore
from them ...
I am glad all of you seem to be okay with this, I was
offering to shut up
if not. Sounds like we need to get a pick machine up somewhere for all
to play on :-)
We are supposed to be getting high-speed wireless access in my
area within the next month or two ... If it works reliably (big if), I am
hoping to get a server set up here eventually which I can use to
make various classic systems available for on-line demos.. The
Mentor would be a good candidate - but given your warnings about
three-character death incantations, I don't know that I would make
the privileged users generally available...
