Fixing MySQL Gem Errors in BT4

8 01 2011

Armitage is a new GUI for Metasploit, which is very interactive and makes hacking or like white-hats call it pen-testing real easy.

To install Armitage, all you have to do is download it and run it on Linux using the following command:

The reason I’m writing this blog is that while trying to run it with Metasploit and MySQL, I came across two errors and it took me a while to find the answers.

I was trying to install Armitage on Backtrack4, not 4r2 version for which the instructions are available here.

So the first error i was getting was when installing the gem mysql. The gem is required if you want to use MySQL database. When I tried installing the gem in Metasploit itself or in shell I was getting the following error:

ERROR: could not find gem mysql locally or in a repository

So I need to update the gem repository and I tried:
gem update --system

This returned an error:
ERROR: While executing gem ... (RuntimeError)
gem update --system is disabled on Debian. RubyGems can be updated using the
official Debian repositories by aptitude or apt-get.

Wandered on the Interwebs for a while and found no solution. So I tried updating the ruby gems by doing:

apt-get install rubygems

And this updated the package and the following command now worked:

gem install mysql

But wait, I’m still not able to connect to the MySQL database in Metasploit or Armitage, when I run the following command:

msf > db_connect root:toor@

The error I get is:

[-] Error while running command db_connect: Failed to connect to the database: uninitialized constant MysqlCompat::MysqlRes

Call stack:
/opt/metasploit3/msf3/lib/msf/ui/console/command_dispatcher/db.rb:1702:in `db_connect_mysql'
/opt/metasploit3/msf3/lib/msf/ui/console/command_dispatcher/db.rb:1548:in `cmd_db_connect'

/opt/metasploit3/msf3/lib/rex/ui/text/shell.rb:143:in `run'
/opt/metasploit3/msf3/msfconsole:128:in `'

Searched for the error on Google and found an article on how to resolve this error on Mac OS X. Unix Linux same shit. Knew it will work. So ran the following command:

sudo gem install --no-rdoc --no-ri -v=2.7 mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/bin/mysql_config

It worked and Armitage now successfully connected to the Metaploit db in MySQL.

Happy Hacking!


Backtrack4 VM Image Slow

8 04 2010

After running the Backtrack 4 image, I found the image to be running really very slow on my Vista box with Workstation 6.5. After digging around, I found that this is because of the aRtsd daemon using 80% of the CPU. Rtsd is the sound server daemon. So to fix this problem, you can either kill the daemon or turn it off. See below on how-to-do:

To kill the process
kill -9

To turn of the service
KDE -> System->Settings->Sound & Multimedia -> Sound System -> Uncheck [Enable the sound system]
