Automated Pattern Discovery From Network Traffic (2)

Last time, I described a way to find pattern strings in network traffic using machine-learning tools and techniques and it is the goal of this post to describe the method and results of applying these techniques to real network traffic. As an experiment or proof-of-concept, I looked for patterns in Bit-torrent traffic. The results look very promising....

Automated Pattern Discovery From Network Traffic

From time to time I browse the projects listed on freshmeat.net. I came accross Sally, a tool for mapping strings into vector spaces. This mapping allows one to apply machine learning techniques and data mining to the analysis of string data. I looked at two of the examples given; Sally can be used to map documents to a vector space and build...

Test Code Coverage with Objdump and Valgrind

I was working on a C++ project recently where gcov inexplicitly failed to report correct results, especially for template files. Some templated code was incorrectly being reported as not-covered by my tests. Instead of doing the right thing by finding out why gcov was not working with my source code, I decided to write a python script that combined...
