我們經(jīng)常為客戶做大量的密碼破解工作。有時候是由于我們破解了一個系統(tǒng)，尋找有無密碼重復使用的情況；有時候是由于我們在獲取密碼復雜性方面的統(tǒng)計數(shù)字，以證明某個觀點；有時候我們只是試圖破解WPA-PSK。不過，你有一套很安全的系統(tǒng)很要緊。我們最近改建了自己的一臺密碼破解服務器，下面介紹了關于其規(guī)格和配置的一些信息。

硬件規(guī)格

主板：EVGA Z68 FTW 160-SB-E689-KR Extended ATX英特爾主板
 
處理器：英特爾酷睿i7-2600K 3.4GHz LGA 1155 95W四核臺式機處理器

 
海盜船（CORSAIR）CAFA50 120mm CPU散熱器 

 
電源：海盜船專業(yè)系列Gold AX1200（CMPSU-1200AX）1200W ATX12V v2.31 / EPS12V v2.92 SLI Certified 80 PLUS GOLD認證模塊化主動功率因數(shù)校正（PFC）電源 

 
機箱：酷冷至尊HAF 932 Advanced RC-932-KKN5-GP黑鋼ATX全塔式偉訊機箱，帶USB 3.0 

 
存儲設備：2只日立Deskstar 3TB 3.5英寸SATA 6.0Gb/s內(nèi)置硬盤——裸盤 

 
內(nèi)存：海盜船XMS3 16GB（4 x 4GB）240針DDR3 SDRAM DDR3 1333臺式機處理器 

GPU：4塊藍寶Radeon HD 6950 Dirt3 Edition 100312-3SR 視頻卡，帶Eyefinity技術

共計：2629.78美元

#p# 安裝
硬件改裝
雖然主板上有一個插槽可以使用，但是第四塊視頻卡其實與其他的視頻卡合不來（視頻卡相互排擠），于是我們決定采用一種“獨特”的方式來安裝它。我確信氣流/散熱方面的專家對這個決定不高興，但這又是唯一的辦法。使用靈活的PCIe擴展槽，我們總算裝上了該視頻卡。 

 
靈活的PCI Express擴展槽

如右圖所示，我們在機箱背面上鉆了幾個空眼，為視頻卡上的連接器留出地方，并提供一定的穩(wěn)定性。

 
 
硬盤/RAID配置

3TB硬盤要求我們利用Grub2和GPT。盡可能妥善地備份這個系統(tǒng)也很重要，以防出現(xiàn)硬件故障，所以我們想要使用RAID 1來確保簡單。

通過BIOS的英特爾FakeRAID——失敗

最初我們想通過主板內(nèi)置的英特爾RAID功能來使用RAID 1，但是它似乎無法完全得到dmraid或Ubuntu Server 10.04.3的支持。不知什么原因，它在parted中出現(xiàn)的只是801GB硬盤；安裝不允許在該801GB中創(chuàng)建任何分區(qū)。于是我們放棄了它。

想了解更多信息，請訪問：http://ubuntuforums.org/showthread.php?p=11477517

整個磁盤的軟件RAID（mdraid/mdadm）——失敗
我們希望硬盤完全冗余，于是試圖創(chuàng)建一個很大的根分區(qū)和一個交換分區(qū)，分區(qū)設置為linux_raid類型。若使用這個方法，Ubuntu安裝很正常，但是grub安裝失敗。折騰了一番后，我們還是無法成功地將grub安裝上去。于是，我們采用了一種比較傳統(tǒng)的分區(qū)方法。

想了解更多信息，請訪問：http://ubuntuforums.org/showthread.php?p=11477507

根分區(qū)的軟件RAID（mdraid/mdadm）——成功了！

下面介紹了我們最后如何對這兩個（/dev/sda, /dev/sdb）硬驅進行分區(qū)。我們是在安裝之前，通過啟動到自生系統(tǒng)（LiveCD）完成這一步的。

root@ubuntu:~# parted /dev/sda mklabel gpt  
root@ubuntu:~# parted -a cyl /dev/sda unit s mkpart grub 34 4130  
root@ubuntu:~# parted -a cyl /dev/sdb set 1 bios_grub on  
root@ubuntu:~# parted -a cyl /dev/sda unit s mkpart boot 4131 1052706  
root@ubuntu:~# parted -a cyl /dev/sda unit s mkpart primary 1052707 5852144526  
root@ubuntu:~# parted -a cyl /dev/sdb set 3 raid on  
root@ubuntu:~# parted -a cyl /dev/sda unit s mkpart swap 5852144527s 5860533134s  
root@ubuntu:~# parted /dev/sda unit compact print free  

Model: ATA Hitachi HDS72303 (scsi)  
Disk /dev/sda: 3001GB  
Sector size (logical/physical): 512B/512B  
Partition Table: gpt  
Number Start  End   Size  File system   Name   Flags  
1   17.4kB 2115kB 2098kB         grub   bios_grub  
2   2115kB 539MB  537MB  ext2      boot  
3   539MB  2996GB 2996GB xfs       primary raid  
4   2996GB 3001GB 4295MB linux-swap(v1) swap 

#p# 然后在安裝過程中，我們通過mdraid為第三個分區(qū)配置了RAID1。下面是安裝完成后mdadm.conf看起來的樣子。

root@ubuntu:~# cat /etc/mdadm/mdadm.conf | grep ARRAY 
ARRAY /dev/md0 level=raid1 metadata=1.0 num-devices=2 UUID=43dd56be:498abe6a:4421ece1:0659a71e name=0 

我們在安裝過程中為GDM選擇了“Ubuntu Desktop”程序包。這點很重要，因為之后在GPU上，要是沒有X.org服務器在運行，就無法進行破解。我們起初有一個啟動腳本，就為了在后臺執(zhí)行xinit命令，但這使得可以實際訪問系統(tǒng)的任何人都能訪問根外殼。這是個壞主意。

一旦安裝完成，grub2還是沒有立即啟動，于是我們再次從自生系統(tǒng)（LiveCD）啟動，用手動方式來安裝：

root@ubuntu:~# mount -t xfs /dev/sda3 /mnt  
root@ubuntu:~# cp /mnt/etc/mdadm/mdadm.conf /etc/mdadm/mdadm.conf  
root@ubuntu:~# mdadm --assemble /dev/md0  
mdadm: /dev/md0 has been started with 1 drive (out of 2).  
root@ubuntu:~# umount /mnt  
root@ubuntu:~# mount /dev/md0 /mnt  
root@ubuntu:~# mount /dev/sda2 /mnt/boot  
root@ubuntu:~# for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done  
root@ubuntu:~# chroot /mnt  
root@ubuntu:/# grub-mkdevicemap  
root@ubuntu:/# grub-mkconfig -o /boot/grub/grub.cfg  
Generating grub.cfg ...  
Found linux image: /boot/vmlinuz-2.6.32-35-generic  
Found initrd image: /boot/initrd.img-2.6.32-35-generic  
Found memtest86+ image: /boot/memtest86+.bin  
root@ubuntu:/# grub-install --no-floppy --recheck --modules='biosdisk ext2' /dev/sda  
Installation finished. No error reported.  
root@ubuntu:/# grub-install --no-floppy --recheck --modules='biosdisk ext2' /dev/sdb  
Installation finished. No error reported. 

然后重啟動，現(xiàn)在我們看到了Ubuntu Gnome登錄提示符！

#p# 安裝OpenCL和AMD驅動程序

接下來我們需要安裝所有那些圖形卡。由于這些是AMD卡，我們將安裝AMD OpenCL軟件開發(fā)工具包（SDK）和AMD驅動程序。

user@ubuntu:~$ mkdir AMD-APP-SDK-v2.5-lnx64
user@ubuntu:~$ cd AMD-APP-SDK-v2.5-lnx64/
user@ubuntu:~$ wget http://developer.amd.com/Downloads/AMD-APP-SDK-v2.5-lnx64.tgz
user@ubuntu:~$ tar -zxvf AMD-APP-SDK-v2.5-lnx64.tgz
user@ubuntu:~$ sudo ./Install-AMD-APP.sh

作為一種檢查機制，我們可以使用HelloCL測試來確保一切工作正常：

user@ubuntu:~$ cd /opt/AMDAPP/samples/opencl/bin/x86_64
user@ubuntu:/opt/AMDAPP/samples/opencl/bin/x86_64$ ./HelloCL
HelloCL!
Getting Platform Information
No protocol specified
Creating a context AMD platform
Getting device info
Loading and compiling CL source
Running CL program
Done
Passed!

看起來很好，現(xiàn)在不妨安裝驅動程序：

user@ubuntu:/opt/AMDAPP/samples/opencl/bin/x86_64$ cd ~/
user@ubuntu:~$ sudo apt-get install libssl-dev build-essential python-dev libpcap-dev
user@ubuntu:~$ export AMDAPPSDKROOT="/opt/AMDAPP"
user@ubuntu:~$export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/opt/AMDAPP/lib/x86_64":"/opt/AMDAPP/lib/x86"
user@ubuntu:~$ export ATISTREAMSDKROOT=$AMDAPPSDKROOT
user@ubuntu:~$ chmod +x ati-driver-installer-11-11-x86.x86_64.run
user@ubuntu:~$ sudo ./ati-driver-installer-11-11-x86.x86_64.run

#p# 安裝支持OpenCL的Pyrit

Pyrit很出色，但是它并沒有考慮到最新的AMD SDK。如果你到目前為止一直按要求來安裝，應該沒問題。不過，你會發(fā)現(xiàn)我們不得不作幾處更改，以便讓一切運行起來正常。

user@ubuntu:~$ wget http://pyrit.googlecode.com/files/cpyrit-opencl-0.4.0.tar.gz
user@ubuntu:~$ tar -zxvf cpyrit-opencl-0.4.0.tar.gz
user@ubuntu:~$ cd cpyrit-opencl-0.4.0/
user@ubuntu:~/cpyrit-opencl-0.4.0$ vi setup.py

編輯setup.py，在第55行后面新建一行，添加：

'/opt/AMDAPP/include', \

一旦pyrit有了所有正確的include指令，就可以開始編譯/安裝了。

user@ubuntu:~/cpyrit-opencl-0.4.0$ python setup.py build
user@ubuntu:~/cpyrit-opencl-0.4.0$ sudo python setup.py install
user@ubuntu:~/cpyrit-opencl-0.4.0$ cd ..
user@ubuntu:~$ wget http://pyrit.googlecode.com/files/pyrit-0.4.0.tar.gz
user@ubuntu:~$ tar -zxvf pyrit-0.4.0.tar.gz
user@ubuntu:~$ cd pyrit-0.4.0
user@ubuntu:~/pyrit-0.4.0$ python setup.py build
user@ubuntu:~/pyrit-0.4.0$ sudo python setup.py install
user@ubuntu:~/pyrit-0.4.0$ sudo pyrit list_cores

如果你使用一塊視頻卡，應該沒問題；不過由于我們有四塊，只好使用aticonfig實用工具來全部啟用它們：

user@ubuntu:~$ sudo service gdm stop
user@ubuntu:~$ sudo aticonfig --adapter=all --initial
user@ubuntu:~$ sudo service gdm start

我們運行了一些快速的pyrit基準測試，情況看起來很好：

user@ubuntu:~$ sudo pyrit benchmark
Pyrit 0.4.0 (C) 2008-2011 Lukas Lueg http://pyrit.googlecode.com
This code is distributed under the GNU General Public License v3+
Running benchmark (151933.5 PMKs/s)... /
Computed 151933.49 PMKs/s total.

#7: 'CPU-Core (SSE2)': 879.4 PMKs/s (RTT 2.8)
#8: 'CPU-Core (SSE2)': 961.1 PMKs/s (RTT 2.8)

#p# 安裝帶CAL++支持的pyrit

雖然151933.5 PMKs/s很好，但是我們知道這不是其應有的速度。所以我們決定采用使用CAL++的SVN版pyrit（0.4.1-dev），而不是使用帶OpenCL的穩(wěn)定版pyrit（0.4.0）。

我們要做的第一件事就是卸載pyrit（請相信我，這么做是值得的）：

user@ubuntu:~$ cd pyrit-0.4.0/
user@ubuntu:~/pyrit-0.4.0$ sudo python setup.py install --record files.txt; sudo rm $(cat files.txt)
user@ubuntu:~pyrit-0.4.0$ cd ../cpyrit-opencl-0.4.0/
user@ubuntu:~/cpyrit-opencl-0.4.0$ sudo python setup.py install --record files.txt; sudo rm $(cat files.txt)

現(xiàn)在下載CAL++（http://sourceforge.net/projects/calpp/），并安裝它：

user@ubuntu:~$ sudo apt-get install libboost-all-dev cmake
user@ubuntu:~$ tar -zxvf calpp-0.90.tar.gz
user@ubuntu:~$ cd calpp-0.90

CAL++需要作幾個變更，以便順利找到AMD SDK庫，所以編輯CMakeLists.txt，注釋掉這些行（即在每行開頭添加“#”）：

FIND_LIBRARY( LIB_ATICALCL aticalcl PATHS "$ENV{ATISTREAMSDKROOT}/lib" )
FIND_LIBRARY( LIB_ATICALRT aticalrt PATHS "$ENV{ATISTREAMSDKROOT}/lib" )
FIND_PATH( LIB_ATICAL_INCLUDE NAMES cal.h calcl.h PATHS "$ENV{ATISTREAMSDKROOT}/include" )

添加這些：

FIND_LIBRARY( LIB_ATICALCL aticalcl PATHS "/opt/AMDAPP/lib" )
FIND_LIBRARY( LIB_ATICALRT aticalrt PATHS "/opt/AMDAPP/lib" )
FIND_PATH( LIB_ATICAL_INCLUDE NAMES cal.h calcl.h PATHS "/opt/AMDAPP/include/CAL" )

現(xiàn)在我們編譯，然后安裝：

user@ubuntu:~/calpp-0.90$ sudo make install

由于CAL++已安裝，你可以下載pyrit的開發(fā)分支，完成安裝的其余步驟。

user@ubuntu:~$ sudo apt-get install subversion
user@ubuntu:~$ svn checkout http://pyrit.googlecode.com/svn/trunk/ pyrit_svn
user@ubuntu:~$ cd pyrit_svn/cpyrit_calpp/

我有沒有提到這是開發(fā)版本？這意味著你得作幾個變更：

編輯setup.py第28行，應該是：
VERSION = '0.4.1-dev'

編輯setup.py第35行，應該是：
CALPP_INC_DIR = '/opt/AMDAPP'

編輯setup.py第41行，應該是：
CALPP_INC_DIRS.append(os.path.join(CALPP_INC_DIR, 'include/CAL'))

好了，我們已準備好了編譯和安裝：

user@ubuntu:~/pyrit_svn/cpyrit_calpp$ python setup.py build
user@ubuntu:~/pyrit_svn/cpyrit_calpp$ sudo python setup.py install
user@ubuntu:~/pyrit_svn/cpyrit_calpp$ cd ../pyrit/
user@ubuntu:~/pyrit_svn/pyrit$ python setup.py build
user@ubuntu:~/pyrit_svn/pyritsudo python setup.py install

#p# 向下滾動，即可看到基準測試部分下面的結果。我們得到了額外的20,000 PMK/s！

oclHashcat
oclHashcat的安裝極其容易。只要解壓縮即可。

user@ubuntu:~$ sudo apt-get install p7zip
user@ubuntu:~$ p7zip -d oclHashcat-0.26.7z

john

user@ubuntu:~$ wget http://www.openwall.com/john/g/john-1.7.8-jumbo-8.tar.bz2
user@ubuntu:~$ tar -jxvf john-1.7.8-jumbo-8.tar.bz2
user@ubuntu:~$ cd john-1.7.8-jumbo-8/src/
user@ubuntu:~/john-1.7.8-jumbo-8/src$ make linux-x86-64

接下來，我們下載了KoreLogic的Defcon 10規(guī)則集，并將它們添加到我們的john.conf

user@ubuntu:~/john-1.7.8-jumbo-8/src$ cd ../run
user@ubuntu:~/john-1.7.8-jumbo-8/run$ wget http://contest-2010.korelogic.com/rules.txt
user@ubuntu:~/john-1.7.8-jumbo-8/run$ cat rules.txt >> john.conf

rcracki

較新的彩虹表（Rainbow Table）是.RTI文件，這意味著它們是索引彩虹表，運行速度應該比普通彩虹表要快。由于我們有幾個這樣的彩虹表，所以需要安裝rcracki。
user@ubuntu:~$ wget http://www.freerainbowtables.com/download/rcracki_mt_0.6.6_src.7z
user@ubuntu:~$ p7zip -d rcracki_mt_0.6.6_src.7z
user@ubuntu:~$ cd rcracki_mt_0.6.6_src/

編輯Makefile，更改OPTIMIZATION變量，應該是：
OPTIMIZATION = -O3 -mtune=native
現(xiàn)在我們可以編譯了。

user@ubuntu:~/rcracki_mt_0.6.6_src$ make
user@ubuntu:~/rcracki_mt_0.6.6_src$ sudo make install
user@ubuntu:~/rcracki_mt_0.6.6_src$ cd ..
user@ubuntu:~$ sudo mv rcracki_mt_0.6.6_src /cracking/bin/
user@ubuntu:~$ cd /cracking/bin/rcracki_mt_0.6.6_src
user@ubuntu:~/rcracki_mt_0.6.6_src$ sudo mkdir src

user@ubuntu:~/rcracki_mt_0.6.6_src$ sudo chmod o+w rcracki.*

rcrack

為了支持比較舊的.RT彩虹表，我們可以使用標準的rcrack。版本1.5是預先編譯的，所以安裝其實只是下載和解壓縮的過程。
user@ubuntu:~$ wget http://project-rainbowcrack.com/rainbowcrack-1.5-linux64.zip
user@ubuntu:~$ unzip rainbowcrack-1.5-linux64.zip

#p# 下載
彩虹表

設想一下：沒有大量彩虹表的密碼破解服務器會怎樣？幸好我們有一大批技術高手，所以沒必要把時間花在下載上。我們拷貝了以下的彩虹表：

fastlm_alpha-numeric#1-7_0
lm_all-space_1-7
lm_alpha_1-7
lm_alpha-numeric_1-7
lm_alpha-numeric-symbol32-space_1-7

字列表

字列表（Wordlist）是你似乎從來不嫌多的東西之一。我們匯集了一些流行的字列表；我確信，一旦服務器進入生產(chǎn)環(huán)境，我們會獲得其他字列表方面的許多建議。

#p# 一般訪問

由于rcrack、 rcracki和john某種程度上需要從各自的程序目錄下運行，于是我創(chuàng)建了幾個別名，讓用戶可以輕松進入到合適的位置。另外，我們把大多數(shù)這些安裝放到了一個集中位置（/cracking/bin），那樣我們就能輕松維護（沒有這些工具的實際程序包）。
