Metasploit Development Environment
The Metasploit Framework is a pretty complex hunk of software, at least according to Ohloh. So, getting started with development can be daunting even for veteran exploit developers. This page attempts to demystify the process of getting your Metasploit development environment set up through submitting a "pull request" to get your exploit into the standard distribution.
This documentation assumes you're on some recent version of Ubuntu Linux. If not, then you're going to be on your own on how to get all your dependencies lined up. If you've successfully set up a development environment on something non-Ubuntu, and you'd like to share, let us know and we'll link to your tutorial from here.
Throughout this documentation, we'll be using the example user of "Fakey McFakepants," who has the e-mail address of "mcfakepants@packetfu.com" and a login username of "fakey."
Apt-Get Install
The bare minimum for working on Metasploit effectively is:
apt-get -y install \
build-essential zlib1g zlib1g-dev \
libxml2 libxml2-dev libxslt-dev locate \
libcurl4-openssl-dev git-core \
libssl-dev openssl autoconf bison curl wget \
postgresql postgresql-contrib libpq-dev
Note that this does not include an appropriate text editor or IDE, nor does it include the Ruby interpreter itself. We'll get to that in a second.
RVM
Most (all?) standard distributions of Ruby are lacking in one regard or another. Lucky for all of us, Wayne Seguin's RVM has been getting steadily more excellent in providing several proven Ruby interpreters. Visit https://rvm.io/ to read up on it, or just trust that it'll all work out with a simple:
$ curl -L get.rvm.io | bash -s stable
Followed by
$ source ~/.rvm/scripts/rvm
And finally:
$ rvm install 1.9.3-p125
What this all does is fetch RVM, which performs a bunch of shell voodoo, and finally installs Ruby version 1.9.3 patchlevel 125 (there are lots of other Rubies to choose from, but we like this one the most right now). Assuming all goes as planned, you should end up with something like this in your shell.
Editor / IDE
Once that's all done, you can move on to setting up your preferred editor. Far be it from us to tell you what editor you use -- people get really attached to these things for some reason. Once we have some docs put together for sensible defaults for a couple of the more popular editors out there, we'll list that here.
Create a GitHub Account
The entire Metasploit code base is hosted here on GitHub. If you have an old Redmine account over at dev.metasploit.com, that's not going to do much for you since the switch-over. The process for creating an account is pretty simple.
