I am looking for data sets published by researchers or freelancers which can be used for the purpose of IDS/IPS testing and evaluations. The data sets may be for portscans, DoS attacks, Remote to Local attacks, User to root attacks, or all of them. The bigger, the better.

Something on the lines of DARPA Intrusion Detection Evaluation Data set will exactly suit my needs. (<http://www.ll.mit.edu/mission/communications/ist/corpora/ideval/data/index.html>)
