I recently was asked by some guys on my team if it was possible to get email notifications for every commit to svn with a description of what was removed, what was committed and a diff if possible. Now it seems like this would be easy and maybe even built into subversion so I checked into that first. There was a ruby script which can be made as a hook-script which is supposed to send email notifications. I spent quite some time trying to get it to work and didn’t have much luck so I decided to research some other options. I ran across a python program which was written specifically for this task called svnmailer.

Below I will detail the steps needed to get svnmailer working on your system:

Before getting into the details of Dmitry please see this article relating to a Segmentation Fault that can occur with Dmitry on Backtrack 4.

We have been working on a bunch of Backtrack 4 articles recently and one that I started writing awhile back but never finished was on Dmitry or the Deepmagic Information Gathering Tool. When using the TCP Portscan module combined with the output to a file switch, which is done using the -p switch for the TCP Portscan and -o + filename for the output to a file, you will receive a Segmentation Fault. Below is an example when running Dmitry from within Backtrack 4.

Last night I was working on a project for a customer where the application was going to reference external images after the changes I made. One of the custom parts of the project included modifying the thousands of rows that currently existed in the MySQL database. I needed away to modify one of the columns in a MySQL database table by adding data to the front of that column in each row.
