WEKA Tool, Learning Algorithms, KDD CUP 1999 Dataset, SNORT Rules

The idea is to induce SNORT rule using machine learning. WEKA tool shall process the dataset and generate rules in certain format. Then we can convert the output of WEKA into SNORT rules.

I need a support in using WEKA tool and choosing the right algorithm to induce SNORT rules.

Any one has the full experience in using WEKA tool, learning algorithms, KDD CUP 1999 dataset?
