*** CALL FOR GLUTTONS FOR PUNISHMENT
===============================================================================
The Happy Hacker project to teacher basics has
become *too*
successful. Lots of our 2000 readers are complaining
that we are
overloading them with information.
Is there anyone who would be willing to moderate
an intermediate
hacker education list? That way the newbies won't
have to put up
with baffling Unix wizard details, and the more
advanced hackers
don't have to read about IRC wars and Win95 tricks.
Advantages: lots of media attention, and a chance
to build your
reputation. This could lead to a career as
a computer security
consultant, journalist or narc! (Just kidding! The
FBI is too cheap
to hire more narcs.)
Disadvantages: lots of media attention, work
for no pay, have to
put up with flames and rumors that you are a narc,
get hit by email
bombs and people cracking into your Internet hosts
and wiping
system files.
I would also like to hand over moderation of
the Happy Hacker list
to someone who would agree to our policies on flame
control, no
boasting about breaking the law, no naughty words,
and spelling and
grammar control.
If anyone would be kind enough to take on all
this moderator work,
I would have time to turn out a bunch more Guides
to (mostly)
Harmless Hacking.
Never fear, if no one comes forward, I'm keeping
up this work. But
it would sure be fun to have time to finish up all
those
half-written Guides to (mostly) Harmless Hacking!

First, I would check out: http://www.feist.com/~tqdb/texts/hacknov.html
for a very good Novell Netware security reference.
I don't think any
Novell admin should be without a copy.
Second, unless you are able
to brute force hack the password of an
account with administrative privileges you'll probably
just have to
physically power down your server. The main
problem with this whole
situation is your lack of a keyboard right now.
If I understood
correctly rebooting the server should re-enable
the keyboard so you can
get back to work. Just try to make sure that
all users are logged off
and files are closed before shutting the server
down.
Third, basically look through
the Hacking Novell Netware FAQ and pay
particularly close attention to the sections on
how to recover the
administrator password. This should be the
final step in gaining
supervisory control over the server again.
Then tell your company to
file suit against the former admin..
If all else fails, pay for
some real support.

*** LINUX HELP
===============================================================================
From: Timothy Ward <tbw@ruined.all-net.net>
I don't know why, but there is a bit of a mystification
around PPP
and Linux. It really is an easy task. I would suggest
reading the
PPP-HOWTO. Or, if the person who cannot figure
it, could email me
directly I'd be glad to walk him/her thru it. Thanks,
and have a
wonderful day.

From: "Stephen James" <sjamesflorida-wellington@worldnet.att.net>
I *am* a newbie, but Linux loads well on my system.
In other
words: USE AT YOUR OWN RISK. I don't want
flames and bombings
because somebody's system won't work. If you
read this and find
that you have no idea what I'm saying, DON'T try
this.
The "setup" command on my Slackware Linux
system makes it somewhat
difficult to setup LILO (LInux LOader) because of
the extensive
prompts and menus, even though it is more secure.
Keep in mind
that I'm assuming you already have Linux installed.
Don't try this
if you know nothing about Linux. If you don't
mind hand hacking,
edit your /etc/lilo.conf file to look something
like this. Change
*only* the portions of my file that I list:
_________________________________________________________________
boot = /dev/(drive Linux is on; *not* the partition)
_________________________________________________________________
image = /vmlinuz
root = (*now* enter the partition, or the drive)
label = your choice (Linux?)
_________________________________________________________________
other = (partition of win95)
label = (your choice)

*** LOOKING FOR SAN DIEGO HACKERS
===============================================================================
From: Matt Ooi <coder@electriciti.com>
I've seen a lot of people posting requests for
hackers in their
area... any San Diego hackers out there?
Well, I do have a legitimate question. Under
Linux, is there any
way to shell out of procmail or sendmail, short
of ^Z (Suspend)? If
not, how about sasteroids? The reason I ask is because
on my system
I noticed they have suid/gid permissions and are
a potential
security hole: should someone be able to shell out
of them, they
would effectively be root.

hullo there, jay!
cookies are tiny bits of information on yourself
that are saved on
to your hard disk by a web server. I'm sure you've
encountered
websites which greet you when you log on to them
and allow you to
customize what u want to see. or those shopping
mall sites where
you surf around and put your purchases in a shopping
cart.
all the info used in these systems are saved
in your local computer
via a cookie. each web site saves its own cookie
in your hard disk.
cookies are annoying and controversial. but some
think they're
better saved on your HD than on the web servers

Uh...I read the hacker Crackdown, too, but I
recall that it was the
phone company that busted the MOD, not LOD. I believe
Chris was
arrested also. Then Chris & Co. set up
the Security firm. MOD
messed with them and they started complaining to
the FBI. The
business went under, MOD went to jail, got out of
jail, got jobs.
It has been a while since I read the book.
Moderator:
You can get details of the role LOD played in busting
MOD in the
book _Information Warfare_ by Winn Schwartau, chapter
11. Since
Winn has worked closely with Goggans (sorry, I mispelled
his name
earlier), I am inclined to believe Winn's version
of the story.
===============================================================================
*** X WINDOWS TRICK
===============================================================================
Anonymous:
I've noticed a little feature in the network
of our school that
could be interested for "happy hackers,"
since I'm talking of
"internal hacking" (this thing won't work
outside your network, I
think) and it won't damage anything.
We are running a network on AIX version 4 with
IBM (NCD) X
Terminals ; the X Window version running on this
network is release 5
Now to the interesting part : when a X workstation
closes its
current session, there are two seconds before the
magic cookie is
installed ; so you can open a display to any workstation
if you
connect to it in these two seconds.
But why is it useful ? Simple ! When you have
a display attached to
a workstation, you keep it until the current X session
is over ;
that means you just have to wait for someone to
log on this
station, and after he's connected just send a XDisableAccessControl
to the display you have created This will cause
the workstation to
disable its magic cookie (as if the user typed xhost
+)
And then you can do everything you want on this
workstation ... If
someone is interested, my next post could be how
to have fun with a
workstation in xhost + : how to kill processes,
log keys, send
unremoveable windows, make the station beep and
a lot of other
harmless things :)
Now to be clearer a simple program that could
do this:
------------------------------------------------------------------------------
/* When you include all there are never problems :) */
#include <stdio.h>
#include <stdlib.h>
#include <X11/X.h>
#include <X11/Xlib.h>
#include <X11/Intrinsic.h>
#include <X11/StringDefs.h>
#include <X11/Xutil.h>
#include <X11/Shell.h>
main ()
{ Display *d;
char c;
d=XOpenDisplay("funny_station");
if (d==NULL) { printf("Error,access denied\n");
exit(0); }
fflush(stdin);
c=getchar();
/* Now just wait for someone to log on */
XDisableAccessControl(d);
/* And the workstation is in xhost + */ }
------------------------------------------------------------------------------
You compile this with gcc -lX11
Simple and short no ?
Now the questions :
* What systems are subject to this "bug"
; I checked another AIX in another
school and you could "connect"
this way on every "unlogged"
station, there wasn't any two seconds
limit (and so was our
network before I told our admin ...
so perhaps all AIX systems
have the session manager configured
this way on default) ; I
think that it doesn't work with HP terminals
?
So please if you want to do something useful,
stop pinging on IRC
and email bombing and check if this works on your
nearest
workstation :)
* I don't think that this will work "outside"
since the
XDisableAccessControl only works if
the station that sends this command
is on the same domain that the one which
started the session ? Or does it ?
* Could it work with X11 release 6 ?
* It is safe because you can't get passwords easily
on the "login session"
(xlogin on AIX) : the login window doesn't
accept changing its
attributes to KeyPressEvent or KeyReleaseEvent
; you just have to
wait for a telnet :)
So I think that a good idea would be to begin
a list of funny things to do
on X Window like this one ... I am just a beginner
in C and I think this
system has a lot of potential for a hacker :)
In conclusion, if this is published, PLEASE TEST
IT ON YOUR WORKSTATIONS and
let's make a summary of harmless weaknesses in different
X-Window systems !

*** WIN95 TRICKS

Make this anonymous....
I have a Compaq Presario 9660 and it came with
this little fun
program called "Presario Vault". What
this program does is hide any
selected folders and/or files and keeps them locked
with a master
password and a password for the individual file.
So I, being the
smart-ass that I am, decided to hide some useless
files and put in
some worthless passwords that I would forget. Now
I am trying to find
a way to get to the files without a password. I
have torn the
registry apart and looked in every INI file.. Would
anyone know about
this program and how to break it??

To edit the windows help screen (the one that
comes up when you
boot up windows), click the start button on the
task bar, click
run, and type in REGEDIT. that will take you
to the registry
editor. Once there, go into the dir:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\EXPLORER\TIPS
Double click on the line that you want to edit
(on the right frame)
and go for it.
Also, to make the start button go quicker without
the delays, go
into the regedit program like you did above --^
and then go into
the dir:HKEY_CURRENT_USER\control panel\desktop
in this dir look
for a value called menushowdelay and hit enter twice.
Then, set
the value to 100. Its probably set at 400 right
now. You'll have
to reboot to see any change.

In fact how do you know I don't work for the

In fact, come to mention it how do I know that

This idea is terrible, and I'll tell you why.
Firstly, a spam is
something that in Usenet usually refers to something
that is
completely off topic, and most likely an ad.
If you would post the
GTMHH every time someone spammed, you would have
become a spammer.
You would have posted something which has no relevance
to the
Newsgroup, and if, as you said, you would post it
EVERY time
someone spammed, you would fill the newsgroups with
GTMHHs, and
therefore be a particularly annoying spammer.
To stop spammers,
follow the GTMHH or mailbomb their a**, I find no
ethical problem
with mailbombing a spammer AS LONG AS you do not
damage the ISP in
the process, and my respect for US computer legislation
only goes
so far (so far being two inches from my nose).
But the "fight fire
with fire" concept won't work here. You
wanna get back at a
spammer, you do so, but don't make other people
read more spams.
If they want to do something they'll do it, there
is info on
fighting spam widely available on the net.

From: "Robert RIVIERE" <robert@mail.pf>
;-) every
body!!
Just one thing : Stop talking about email bomb :-@
Email bombing is not hacking for me. Hacking can
be noble.
Hacking is gaining information.
It's more interesting for me to discover new tricks
or new bugs
than get bored with email bomb.
Every body have lost the meaning of the word "Hacking".
Here in France Hackers are very vulnerable (DST,
DGSE) because they
have done rubbish like e bomb, or cracking Transpac
connections to
have free phone connections.
I respect people
who respect the other. What do you think about that?
--------------------------------------------------------------------------
From: plowsky@juno.com (plowsky d phreak)
I couldn't agree more, email bombing and destructive
hacking is
exactly what gives the word 'hackers' a bad meaning
in the public
eye. I've been mail bombed many times, and I guarantee
that it took
longer for them to send the bombs than it did for
me to clean them
up. This kind of childish behavior shouldn't be
considered hacking
by anyone...

From: bbuster@succeed.net (Bronc Buster)
You know, this is really getting sad. This mailing
list is made for
the Newbie who has gotten up the nerve, courage,
and/or guts to
dive into this vast and never ending world of "hacking".
Some of
the self professed "hackers" who write
to this list are totally see
through, and fake. You are trying to Bulls**t your
way through...
Stop wasting my/our time. If a someone asks a question,
try to
answer it. If you don't know the answer, read they
reply and learn
it, don't start shooting off your mouth. 99% (dare
I say 100%) of
the information you need to know if on the Internet...
Ask a question about something, someone will
answer it and then
once you have a lead, pursue it. Real simple. If
the Moderator
would be a little more responsible and post e-mail
that had some
value to this list, this mailing list would lose
the "tarnished"
image it is quickly gained around the net.
This list has turned
into a 30% flame war, 30% Moderators personal problems
and
opinions, and 40% about what this list is really
about. This 40% is
why most of you subscribed (I hope).
Every time I read one of the Happy Hackers, I
learn something, or
remember something I had forgotten (well 40% of
the time I
do).......
PS. do you think I can have my .sig NOT cut off
this as usual?

We've posted Bronc's loooong sig plenty of times.
