Hi,
could someone please point me to a ftp site for PHRACK... thanks..
Now for the OB-hack:
Project:
build an analog to digital converter that outputs the average
of 100 samples on LEDS. use an 8032 controller.
Problem:
The only 8-bit port on the controller has it's high bit busted.
Not on the outside, but somewhere between the outside world and
the chip itself. [ dont ask how long it took to determine this !! ].
The other ports are used for RAM ( the averaging area), the
ROM ( program storage ), and the input from the AD converter.
Coming from a small state university money is scarce, and working
chips even more so, I decided to do a little hack,
besides it was 2 AM on a friday night and the
alternative was to give up and wait to get a new chip on monday.
Solution:
Since I was only using 100 bytes in RAM, I had all those
address lines free, and I was already latching them, so the idea:
Test to see if the high bit needed to be set when writing to the LEDS,
if it did, write to a high enough address in memory, then just take
the high bit input for the LED from the memory address latch. simple.
Moral:
The only thing worse than a programmer with a soldering iron is
a hardware person with software patch.
Footnote:
My lab partner nearly killed me for pulling this one off and the
LAB assistant nearly refused to sign the lab off because of
my hack. ( She is currently a glorified type-setter at GE. Life is
it's own revenge. Hi Lynn! :-))

PS - I hope you didn't become so distracted reading this marvelous
little tidbit that you forgot that you were going to
e-mail me that FTP address.

Thanks! > >___Red Devil___ >)_Dennis_( Well.. since that time, I have had at LEAST 10 people asking me to relay the information on to them. I applaud them for not posting the "usual" "ME-TOO...", since I already wasted enough bandwidth doing that in the hopes that I could re-establish my former hacking connections. WELL.. That was not the case. Not ONE person responded publically, or privately to that request. This is both a public "APOLOGY" for not replying to all the mail messages since I've been swamped lately (and being that today's my birthday! YEA!) and another request for information (an FTP site!) Well... that's about the size of things. I wish I had good news to post.. but, since I've been basically ignored by the keepers of knowledge.. I don't know what else to do. If anyone has a copy of it/ could help me out with an FTP site, either E-MAIL me at V119L94U@UBVMS.CC.BUFFALO, or DGCRAWFO@SUNRISE.ACS.SYR.EDU. (DGCRAWF@UMASS.)

If anyone has a copy of it/ could help me Well, I am one of the Cumputer Underground, and I know where such an FTP site is. The question is....... are you a hacker enough to get the files? So to make this interesting......... I'll give you the site number and tell you the files (Phrack, ATI, AnE, LoD, Narc, PH/un, and papers) are 'hidden' on the site. Another hint: Can you say 'unreadable directory'? Knew you could. The number is: 128.95.138.2 Now, if enough people deluge me with letters, I will post. a capture session of the FTP to PROVE my point. Otherwise, I leave it to the hackers. Now go forth, and collect!

Obl. hack: When sun came out with PTRACE_SYSCALL I wrote a progam that changed the return value of the gethostid(2) system in the traced process and all it's children. (The program patched an endless loop after calls to fork(2). This enabled the program to PTRACE_ATACH the child after fork() had returned in the parent with the child's process if, before the child did anything else.) -- Casper H.S.
