The great PC rebuild

2008-12-31T04:45:00.000-08:00

Its that time of year when its after Christmas and I still have a week before classes start. This is the time when I start to break things and then rebuild them. This year I got some new cooling stuff for my PC and instead of just adding it I decided to tear down the whole system and start from scratch. I have tried to document the process a little bit but pictures cant describe how much work went into this. I am proud of the job I have done.
Here are the parts I will be using.

COOLER MASTER COSMOS 1010 Full Tower Computer Case
EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX Intel Motherboard
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 Dual Channel Kit Desktop Memory
Intel Q6600 quadcore cpu
Asus cd/dvd drive
Western Digital 300 gig Raptor drive
2 Nvidia 8800 gt cards
2 swifttech obsidian waterblocks with the Mosfet heatsinks
H20-220 Apex Ultima CPU liquid cooling kit
800w power supply
Lots of red LED Antek 3 speed fans.

Here is what I started out with. As you can see I completely stripped the box because I had to remove some pieces of the hard drive enclosure in order to allow all the things to fit. The goal I was going for was to create two independent loops of watercooling. One loop for the cpu and one loop for the two nvidia 8800gt's I have. What I planned to do was use the swifttech dual radiator for the gpus and the new quad Blackice GTX480 radiator for the cpus. Here is a pic of the swifttech radiator.

Here is a picture of the monster Blackice 480GTX

The first order of business was to rebuild the case. As you can see I removed the whole hard drive area. I will be moving the hard drive up to the 5 1/2 inch bay area in order to get some more space. I will be mounting the blackice rad on top of the box however I was hard pressed to find a location for the swifttech one but I finally decided on the bottom where the fans used to be and there was already holes for two fans to flow outward. You cant see it in this picture but there are some bars the box sits on to allow airflow underneath. I also decided to paint the box black at the same time. I never really liked the silver much anyway. Here is the modded and painted box with the radiators installed.

Next I installed my swifttech pump and my evga 780i mother board. I also started adding the tubing and planning out my waterflow pattern as I was installing the parts.

Next I added the power supply, the cd/dvd drive and my 300 gig raptor hardrive.

Next I started on the gpu waterblocks. I have two nvidia 880gt's. I run a 4 monitor system so I need the cards running independent and not in SLI. Aircooled my cards ran in the 50c to 70c range depending on the fan speed so I am hoping to knock 10 degrees or so off of that with watercooling. I selected the swifttech obsidian waterblock with the add on mosfet heatsink which is pictured here all put together.

Here is another close up

My work area...

Here I have added the second videocard and all the little odds and ends I forgot. I have filled the entire system with water and turned it on. Everything seems to be working pretty well so far.
My GPU cards are now running at about 29-30 degrees Celcius which is a vast improvement over the 50-60 they were running before.
At the moment I'm still running at a stock 2.4 GHz but I'm going to be going back up to at least 3.6, and maybe more. Here is my sensors output.

Scripts...

2008-12-23T10:28:00.000-08:00

I use some scripts in my rc.lua file which I guess I need to post in order for some of the widgets to work. These are not my original work, I got them from various sources on the inturwub. I cant remember where so I cant give the credit where it is due.

The first one tells you the current or last emerged package.

#!/bin/bash
#emerge-current.sh
tac /var/log/emerge.log |\
grep 'Compiling' |\
head |\
sed -e 's/.*(//' |\
sed -e 's/::.*)//' |\
head -n 1 |\
cut -d \) -f 1

The next one tells the progress in percentage.

#!/bin/bash
# This script will report the progress of the last emerge command run.
tail -n 50 /var/log/emerge.log |\
tac |\
grep -v "Starting retry" |\
grep -iE '([0-9]* of [0-9]*)' -o -m 1 |\
sed -e 's/$.*$ of $.*$/\1 \2/' |\
awk '{print 100.0*$1/$2}'

The next one tells us the status of the current package being emerged.

#!/bin/bash

STATUS=`tail -n 15 /var/log/emerge.log |\
grep -iE "Compiling|Cleaning|AUTOCLEAN|completed|search|terminating|rsync" |\
cut -d ' ' -f "2-" |\
grep -Ev 'Finished\.|Cleaning up\.\.\.' |\
tail -n 1`

#echo "$STATUS"

if [ "`echo "$STATUS" | grep -i compiling`" != "" ]; then echo Compiling
elif [ "`echo "$STATUS" | grep -i cleaning`" != "" ]; then echo Cleaning
elif [ "`echo "$STATUS" | grep -i autoclean`" != "" ]; then echo Autoclean
elif [ "`echo "$STATUS" | grep -i sync`" != "" ]; then echo Syncing
elif [ "`echo "$STATUS" | grep -i search`" != "" ]; then echo Searching
elif [ "`echo "$STATUS" | grep -i completed`" != "" ]; then echo Completed
elif [ "`echo "$STATUS" | grep -i terminating`" != "" ]; then echo Completed
else echo Script Error!
fi

And the final one will show us when the last-sync was. (This one requires the Date::Manip perl module)

#!/usr/bin/perl
use Date::Manip;

$date = `grep "Sync completed" /var/log/emerge.log | tail -n1 | cut -c-10`;
$date = &DateCalc("Jan 1, 1970 00:00:00 GMT",$date);
$date = UnixDate("$date","%A %H:%M");
print "$date";

I also use a little script to show my current ip.

#!/bin/bash
wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//'

And finally I use a script to download a image of the world with the current state of darkness and use it as my desktop. You will have to edit this one to suit your resolution. I have this set as a cron job which executes once a hour to get me the latest desktop picture.

#!/bin/bash
#
# Save this script to somewhere like "/home/(user)", "chmod a+x" it,
# edit it to change the correct IMAGEFILE for your screen size,
# then run "crontab -e" and add a line like this:
#
# 0 * * * * DISPLAY:0 /home/(user)/xplanetdisplay.sh

Awesome Window Manager

I have recently discovered the awesome window manager. It is a tiling window manager which is very light and easy to use. Theres is some documentation at their website http://awesome.naquadah.org/ and they also have a excellent wiki.

Fischer Price "My First FireWall"

2008-04-09T04:18:00.000-07:00

We had an assignment in class this week to write our own personal firewall for a personal PC. We had to use variables and have a least a few outside services running. I thought I may as a well post it here since by default Backtrack does not have a firewall or even IPtables running when it starts up. In the past I'll be honest I've always cheated with a GUI firewall program like Guard Dog or Firestarter but now I am slowly learning to write one from scratch. If you would like to use it just copy and paste it in a file called firewall.sh. Give it exec permissions and start it with ./firewall.sh and stop it with ./firewall.sh stop. Special thanks to linuxchuck for his help with iptable'fu.

Project Evil AP

2008-02-24T15:32:00.000-08:00

My new project these days is wireless routers and all the mods that can be done to them. I know some of this stuff is a little old and has "been done" however it is new to me and I am having quite a bit of fun with it.

I started with a linksys WRT54GL wireless router which is the newest Linux version of their router. ost of the info on the web is for modding the older routers but I did find some for the L including this book.

I highly recommend the book if you are planning on hacking up your router. I will be slowly adding to the blog as I go with pictures.

The first thing I did was upgrade to the latest dd-wrt release. Later on I may switch to open-wrt but at this time dd-wrt had some features I liked. The next thing I did was order a couple of 9db antennas from fab-corp to amp up the my signal a little. At this point I decide to preform the SD card mod which I found in the book I mentioned above. I'm not going to go into the actuall install because there is plenty of info in the book and on the web. This gave me a extra 1.9 gigs of memory.

Now for the software. I configured the router to be a wireless repeater which would repeat the strongest wi-fi signal it could find. I then found a script called Auto AP which takes it one step further. It actively searches out the strongest signal by itself at boot and continues to re scan and stay connected to the strongest open signal. The script can be modified to accept wep keys and preffered essid's.

Since the start of the project I have switched the router to use open-wrt firmware. It is a much smaller app and suites my needs alot better. dd-wrt is great firmware however I felp it was a little boloated with apps I didn't need (kinda like Vista). Anyway I am in the process of getting it built back up into a fully functional MITM type machine.

De-ICE pentest disc 1.100 & 1.110

2007-12-04T12:42:00.000-08:00

I have decided to release videos of the first disc in the de-ice series of pentest challenges. If you do not want to see the solutions DO NOT watch these videos. Special thanks to grendal at http://de-ice.net for providing a safe way to pentest. To complete the challenges you will also need the Backtrack live cd from http://www.remote-exploit.org. All the instructions for setting up the challenge can be found on the De-Ice site. Special thanks to PrarieFire who provided the transcript of the video and had the original idea to document them in a video series.
