Editor's Comments******************************************************************
Opening CommentsOkay, I've been busy at work, so all of the submissions really help a
lot. I don't have time to test everything...but I put most of what is
sent to me into the HHD b/c peer review is a cornerstone of the Open
Source project...having someone put another set of eyes on some code and
suggesting ways to improve it is how Linux came to be, after all. If
you have submitted something that hasn't made it into the HHD, check
your email...I may have sent it back asking you to be more clear about
something, or explain something a little better. I'm just looking for
quality submissions...and remember, the long stuff is best submitted as
a URL...thanks.******************************************************************

Subj: even more weird out urlsHi again all you happy hackerz. Thought Id share something I discovered
a while back after i saw my first dotless ip url and tried some
experiments. you can also create dotted and dotless ip's with hex
numerals ;) lets take the ficticious lan ip 192.168.1.222 . converteach 8-bit address section into hex => 192 = C0 , 168 = A8, 1=01, 222 =
DE. Hex numerals are represented with an 0x in the front. so, if there
is a web server at http://192.168.1.222 , you can also access it via
http://0xC0.0xA8.0x01.0xDE .Now this is the really cool part. you can do a dotless hex ip as well.
try the same address above with only one leading 0x and no dots.
http://0xC0A801DEWhats cool about this is, theoretically you could get numerical
addresses that spell out stuff using the hexadecimal letter-digits A
through F. I have a famous one in mind im going to investigate ;)This may not work in all browsers, but it did in ie4 and ns 4.5 for me.
Hmm, maybe octal will work too? binary?Remember where you saw it first ;) ;)

Subj: reader Submission (Win98)I've got two things to submit. First, Win98 stores startup and shutdown
splash screens just like w95, as logo.sys(for startup) logow.sys(
shutting down, and logos.sys (for "ok to turn off") Simply save a bmp
as one of these names in the dir they came from, copying them first
somewhere else for backup of course, and you're done.THe only trouble I have had with this is on some installs, not being
able to find logo.sys, but I HAVE done it to other W98 boxes, in fact
the W98 logo.sys works with w95! Makes a good trick on somebody!Second, for those with w98 and Personal WEb Server, if you want to use
the premade asp layouts, but dont like that IE4 logo ad a the bottom,
Get the gif you want, and save it to the dir c:\iissamples\default\as ie.gif, saaving the old somewhere else as backup of course. The
code in the layout.css, with the help of other files, create the logo
with ie.gif. I chose netscape's animated gif for my page! Also, if
you want to add java, or just regular html, you can open
c:\wwwroot\default.asp in notepad, and make all the additions you want.Thanks,
Artilect[Editor: I can't test and verify the Win98 startup screen stuff...but
please...NO MORE EMAIL ABOUT THE WIN98 STARTUP SCREEN!!! If you have a
method of changing, it fine...post it on a web page and send me the URL.

above, I have just one word for you..."attributes".]From: "Katt ph®eak" <kattphreak@hotmail.com>

>Would you please help me with my queries?
>Thank you for your time and support.Okay this idea may not work but you should give it a whirl... What you
need to do is set the system to boot a floppy before it boots the hard
drive. To do this before entering the OS you have to get into the
system bios. On my desktop, I have to hit the F1 key when the Gateway
2000 logo pops up as all the nifty little numbers and techno-lingo fly
by on the screen. On my laptop I have to hit the delete key when the
Compaq logo appears. If you don't know how to get into the bios I wouldtry all the F-Keys(F1, F2...), delete, and all the other nifty buttons
like that. Eventually, if you're lucky, the bios will open. Here is
where all the system configurations are located. Things like timezone,
and what boots first. I'm assuming that those security programs have
switched your system to boot the hard drive before the floppy. There
should directions on how to navigate the bios at the bottom or top of
the screen. Follow those directions until you find the boot options.
Switch the bios to boot the floppy drive before the hard drive. Exit
the bios, saving your changes as you do. Then shut down your machine,
pop in your floppy, cross your fingers, and reboot. I hope this helps
you out, so let me know how it goes.Hope I helped,

Subj: A neat batch fileHi all you happy hackers!
I saw the last guide [or the one before, i dunno] and saw that batch
file that clears your documents list. I thought it was quite smart and
so decided to write on that clears your RUN list [i know i always need
it cleared, and its just a principle]Now first you need to export the registry file that keeps the names.
Open up the regedit GUI and export the key :
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Explorer\RunMRU]to c:\windows\runlist.reg
OR
from dos [c:\] type regedit /e c:\windows\runlist.reg
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Explorer\RunMRUnow edit this reg entry and where it says "a"="explorer.exe" [or
whatever] change it to "a"="" for all the letters [b,c,d etc.] and save
it.Now for the batch file:
------CUT HERE--------
@ECHO OFF
echo Clearing your run history...
cd\windows
regedit runlist.reg
cd\
------CUT HERE--------Easy huh? now just save it as clearrun.bat [in c:\windows] and call it
from autoexec.bat by adding the line c:\windows\clearrun.bat to the end
of autoexec. I know its kinda a simple but i like the idea of how it
imports a registry entry...Thanx and keep on hacking!!

Hi there, i see that you have been getting lots og E-mail about how to
change the bootup screens for Win 9x, well I have one for you canchange the NT bootup screen.
Well, ltes get started, the old boring bootupscreen
for server id the "lanma256.BMP" file that is located in the Winnt
directory. Well, to change it just open the "lanma256.BMP" file in
paint and change it to whatever you want it.Ok, Lock off and log in again, see, there is your pic that you wanted,
but now you have to old boring blue type of screen. Well, to chage that
all that you have to do is open a new file in paint and chage the
setting of the page (Open paint, goto Image, attributes ) and set it to
whatever your screen size is (eg 800 x 600, etc), now open the image
that you want to have on you bootup screen with paint, goto "edit" and
select the "select all" option. Right click on it and copy it. Goto the
first paint program that you have open and select "edit", next click on
"Paste". The pic will be in the left hand corner, Move it to the center
of the page. Select the "fill with color" chose you color (eg. black)
and fill the background with it. and save it as "lanma256.BMP" in your
Winnt directory. Log off and log on again, ahhh, the blue is gone and
it's black. Say you have a pic that is 800 x 600 and your screen is set
to 800 x 600 then you just save it as "lanma256.BMP" in your winnt
directory and it will be full screen. I'm not sure, but the Workstation
has the same file, if it doesn't then just look for the *256.BMP file,
it will be thereRegards

More Netcat tricksFrom: lazerus001@juno.com
Hi, I don't know if this will get printed, but its worth a shot. I have
two more NetCat tricks. First is how to use it as an E-Mail sender.
First create a DOS batch file containing this:<system>= your smtp daimon
[Editor: Spell it however you like, but I think the author
meant "daemon".]begin mail.bat
-----------------------
nc -v <system> 25 < mail.txt
-----------------------
end mail.batand mail.txt should contain smtp commands and your message.
example mail.txt
----------
HELO smtp system
MAIL FROM:yourmail@domain
RCPT TO:resiever@domain
DATA
Content-Type:text/plain
X-Mailer:NetCat E-Mail Trick by Fatal Error
Subject:NetCatMesage here.
.
QUIT
----------My second trick is to use NetCat as a defence program with help from my
NCA program. (NetCat Attack, an ASCII flooder I wrote in QuickBASIC.)
By simply using the anti-portscanner/sniffer trick along with NCA you
have a simple BOOBY-TRAP! Using the following batch file:trap.bat
-------------
nc -v -L -d localhost -p 12345 > intrudres.txt
nc -L -d localhost -p 12345 -t -e nca.exe
nc -v -L -d localhost -p 31337 > intrudres.txt
nc -L -d localhost -p 31337 -t -e nca.exe
-------------you've installed our boobytraps. Now when anyone portscans your computer
they'll both get logged and find two "possible" backdoors ;). Now if
they were to telnet to those ports they will be logged again and
they'er telnet screen will be flooded with ascii chars. Also you have
enough to get them kicked off their isp :). I'm not 100% sure, but if
they connect to either port with NetBus or BO their clients should
crash. I highly doubt they were coded to handle a sudden flood of ASCII
code. If you can test that let me know the results. I bet they'll be
interesting.[Editor: Now, this is what I like to see. I guess we'll all have to
email lazerus for a copy of his NCA.exe...or write our own. I like how
lazerus has brought together several concepts...using netcat, defense
of your system, etc. Great job, lazerus!!]******************************************************************
Foolproof ChallengeRecently I received a couple of emails regarding how to get around or
shut down the Foolproof program; most notably, those emails were from
"Freefall" <frfalljd@swbell.net> and jerry kulinger <raz_e_r@yahoo.com>.Interesting approaches, to say the least, neither of which I could test
out.However, here's a challenge for all of you who have been frustrated by
Foolproof, and found a way around it. Come up with a way to make
Foolproof...well...foolproof. Make it as close to impossible, or at
least exceedingly difficult, to get around or shut down FoolProof.Here's my reasoning for the challenge. Obviously, if someone takes the
time and effort to purchase and install the product, it's there for a
reason. So some really bright users feel restricted by it, and devise
methods to get around it.
But is that what 'hacking' is all about? No...so let's take it a step
further. After all, you're not just 'crackers' are you? Let's tell the
sysadmin what you did and how you were able to do so, and then offer to
set things up so that it won't happen again.You'll probably need the user manuals that came with the program as well
as a test system on the network to work with. These shouldn't be a
problem.The goals of this challenge are to secure the box in such a way that
it's exceedingly difficult (ie, a "non-trivial exercise") to circumvent
Foolproof again, AND at the same time, leave the system in a usable
state...users should still be able to access the system and use it for
it's original intent.There are no limitations to this challenge. Given the above stated
goals, 'securing' the box in a block of concrete and sinking it to the
bottom of the ocean is definitely out! The system must still be usable.
Use whatever you like...another, additional product (something that will
require market research), System Policies from the login server (if one
is used), etc.Now for the Open Source part of the challenge...you must post your
method, documented in detail, on a web page, and send me the URL. I
will add the URLs to the HHD, and other readers taking part in the
challenge can verify that your system works, or find a way to
circumvent it. Remember, gentle readers, this is how Unix was
developed over the years...open source and peer review...So...want to take the challenge?

Coming Out Of Your Shell"Have you ever had a dream, Neo, that you were so sure was real, that
you were unable to wake from that dream, how would you be able to tell
the real world from the dream worl......"
Oops.
Good movie, see it anyway.
Hello Happy Hacker!
(You were right, my sysadmin had my netstat "turned off").
Ever want an open source shell, but the functioality *coughGamescough*
in Windows? :)
http://www.litestep.net/builds/ls-0_24_4src.zip
There is your source....
http://www.litestep.net
And there is your new Windows Shell! =)
http://members.xoom.com/tiberianson/mybox.htm <-- My computer
And there is what it looks like! =)
LiteStep is based on XWindows, and is perfect for those of us who like
the way Windows runs our applications, but hate the jludge interface or
just feel like getting in there and beating out some code once and
awhile. It's also a helluva lot easier to set up than X, and never
traps youin 4 colour "pseudocolour" mode (*CoughHelpMeCough*). And
doesn't require SuperProbe(which also hard locks my linux box). I
generally like it, it's fairly stable (fairly, when you crash with this
thing, you crash hard, but it's more stable than windows seems to be,
IMOHO), and turns heads at school on my laptop. ;)
Everything is programmable from a STEP.RC file (XF86Config, anyone?),
including the look and icons inside the wharf there on the side. For
those who are courious, yes, it supports transparancy effects al la
eterm (or Enlightenment, for those who wonder.....), and also supports
Linux themes (though they seem to be a bit unstable in my experiance,
and require some re-writing before they want to work).
If your REALLY into customizing this stuff, grab a copy of
WindowsBlinds or eFX, and get the nifty rollup bars like I have. (Therollup bars in the screenshot are NOT a result of LiteStep, they are a
result of WindowsBlinds).
I like www.annoyances.org/win98/ but they missed one little thing. How
to change your computer from saying, "Starting Windows 98" to "Starting
TiberianSons 31337 Box " (or whatever, mine never actually displays
this). What you do here is make a boot disk (because if you do this on
your hard drive or assume that my words are infallable your going to
regret this really quick), make the boot disk bootable (it is a boot
disk, after all). Set IO.SYS off of READ ONLY (you can leave it
hidden), then use DOS EDIT on IO.SYS. About 25% down (line 394), it
will give you the generic windows 9* blah blah blah. Looks like this:
<<snip>>
$ Starting Windows 98...
$ Windows 98 is now starting your MS-DOS-based program.
$ Windows 98 is now restarting...
$ Press Esc not to cancel MS-DOS mode and restart Windows 98...
<<snip>>
Bingo. That's what we want to see. Now you can change all that stuff
and make it look fairly cool. DO NOT use control codes ("'leet
script"). If you wanna play with punctuation, do so on your boot disk.
In fact, do the whole project on your boot disk until the boot disk
boots! Then copy the boot disks IO.SYS over your own IO.SYS. Most of
the time IO.SYS is located in C:\ (I sure hope it is! <grin>).
Anyhow, I've been doing this for months, I never knew anyone had any
interest in making Windows look cool or recompiling their windows
shells. :) Oh well, any questions ya can just e-mail me. :)
Thank you RavenBlack for showing www.annoyances.org to us. :) The
last thing you want to tweak out is your startup-shutdown screens, so
that can be done here:
http://www.annoyances.org/cgi-bin/ce-showtopic/004_011(notice the annoyances.org).
Anyhow, I hope ya all enjoy this, and remember that replacing your
windows shell and editing IO.SYS carries heavy "You Can Shoot Your Self
In The Foot" warnings. The windows shell might make some things crash
unexpectedly (or, my main complain, FIND seems to not work at all in
Win98 with LiteStep, and neither does AOLIM'er, accoring to my younger
brother). It's also a bit of work to get those icons into the wharf.
As for IO.SYS, PLEASE remember to practice this on a boot disk, OK? :)
Laters,
TiberianSon
2611542
Tiberian@ICDC.COM*APPENDATION*
*APPENDATION*
*APPENDATION*

attrib.<<End>>

Perl CornerFrom: grind@pacbell.net
Well just thought I'd contribute and send in a fairly simple perl
script, after months of getting free scripts, I decided to write my own
and this was my first one. Took me a while to figuring out how to parse
it right, so anywho, here it is:
-----------------------------------------------------------------#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hey man! Just logging your ip address,
$ENV{'REMOTE_ADDR'}
connecting on port $ENV{'SERVER_PORT'}, this info will
come in handy
*evil grin*<br>";
print "Oh I see your using $ENV{'HTTP_USER_AGENT'} for
net surfing,
not bad<br>";
$s = $ENV{'HTTP_USER_AGENT'};
($m) = ($s =~ /W(.*)n/);
if ($m eq 'i'){
print "You should use Unix instead of windows, don't you know
anything? *L*";
}
$h = $ENV{'REMOTE_ADDR'};
($i) = ($h =~ /127(.*)1/);
if ($i eq '.0.0.'){
print "<br>Hey Jeff!";
}
------------------------------------------------------------------(Note that when I say prints out, I mean it'll put the words on the
screen *L*, didn't want to confuse anyone) So here is how it works, it
calls perl from /usr/bin/perl to run the script (which of course isneeded), than says it will use html to print out the info. Next it
prints the nifty little text "Hey man! Just logging your ip address,
$ENV{'REMOTE_ADDR'} connecting on port
$ENV{'SERVER_PORT'}, this info will come in handy *evil grin*<br>" this
prints out your ip address (where it says $ENV{'REMOTE_ADDR'}, it'll
put your ip address ) and the port on the server you used to connect on
(where it says $ENV{'SERVER_PORT'}, it'll put the port number), and of
course, it really doesn't log your ip. BTW, $ENV stands for enviroment
variable, you can do some pretty cool stuff with this guy, at the end,
I'll give you all a url which lists all of them Now the next part is a
little bit more complicated, but its easy to get. So lets look at the
next couple of lines:
-----
print "Oh I see your using $ENV{'HTTP_USER_AGENT'} for
net surfing,
not bad<br>";
$s = $ENV{'HTTP_USER_AGENT'};
($m) = ($s =~ /W(.*)n/);
if ($m eq 'i'){
print "You should use Unix instead of windows, don't you know
anything? *L*";
-----
This prints out "Oh I see your using $ENV{'HTTP_USER_AGENT'} for net
surfing, not bad <br>" pretty simple, and the $ENV{'HTTP_USER_AGENT'}
prints out your browser and system. The next line is what took me a bit
to get, it's saying:
The variable, $s, equals $ENV{'HTTP_USER_AGENT'}
The variable, $m, looks at the variable $s to see if the operating
system has a "W" at the beginning and a "n" at the end now if $m equals
i (the letter in between) it will print out "You should use Unix instead
of windows, don't you know anything? *L*"
-----
$h = $ENV{'REMOTE_ADDR'};
($i) = ($h =~ /127(.*)1/);
if ($i eq '.0.0.'){
print "<br>Hey Jeff!";
----
Now the next part works the same way, so here is how it works: When I
access localhost (my webpage) and go to main.html (where the script is
implemented) it sees if my ip address equals 127 at the beginning and
1 at the end now it sees that if my ip address has a .0.0. in the
middle, print out "<br>Hey Jeff!" (which is my name)Well thetas my contribution to the list, if you want to learn perl go
to, http://www.cgi-resources.com and download some scripts and split
them apart (as I've done here) and see to understand them. Its a simple
concept, just hard to know how to put the "verbs" in there. To learn
the environment variables, go to, http://www.cgi-
resources.com/Documentation/Environment_Variables/, and if you have some
spare time, go to my site, http://degrind.dhs.org (has a link to the
happyhacker *L*)Jeff
[Editor: Thanks, Jeff, for the CGI submission. You can write CGI in
Perl, or Python, VB, etc. To learn more about writing CGI, check out
the site Jeff mentioned at http://www.cgi- resources.com. ]Note: If you are interested in more info about CGI programming, look at
the CGI.pm file in your ActivePerl install. Books are available online
from http://www.mcp.com (create your own personal bookshelf) and
http://www.ora.com. If you have access to an NT web server, and would
rather use ASP, there is a Win32::ASP module available (I haven't played
with it yet...)...Okay, now here's some Perl stuff you all might be interested in...
From: "dave andrews" <dave31_5@hotmail.com>
Subj: PerlHere is a little script that the administrators reading may like. It
allows you to use perl in an interactive format. Just type in the perl
command, press enter and it will be done. Then when you have finished
type exit to end the program.do {
print("> ");
chop($_ = <>);
eval($_);
warn() if $@;
} while ($_ ne "exit");Why would you want to do this? Say for example you have lots of batch
files which you use to perform lots of different tasks, with a little
extra work to this script you can create your own perl command line
interface, which could include all of the tasks you normally handle but
in perl form. Then just add them to this template program with a
command name and you can then just type in that name and it will bedone for you. Just keep adding tasks in separate subs and you can
gradually create your own administrative command line interface for
perl.This example interface includes one task that dose some backing up when
the do#backup command is entered. All custom commands should have do#
as the first part of the command, this separates these commands from
proper perl commands.sub backItUp {
`backup /user/*`;
`delete /user/*.bak`
}sub help {
print("do#backup will perform the nightly
backup\n");
print("help will display this message.\n\n");
}do {
print("> ");
chop($_ = <>);
if (/^do#/) {
backItUp() if /backup/;
}
elsif (/^\s*help/) {
help();
}
else {
eval($_);
warn() if $@;
}
} while ($_ ne "exit");
Just enter help to see instructions on use and exit to leave the
program. Of course any users would need to insert commands that they
