JUNG – Java Universal Network Graph Framework Looks quite advanced… we will see what it can do.

Trying out a graph framework to implement PageRank and other algorithms. We will see how it will work with PageRank. (more…)

Axel came up an idea to write an on-line Tripwire – checking the checksums of files before they are executed. This seems to be quite easily doable using LSM. however, they are a few issues that need to be understood:

• Execution of scripts/perl programs, etc. – cannot prevent it
• Dynamic library loading – how to do it in LSM
• Policy loading – how to read policies in Kernel mode

Hum…. such thing already exists and is an open source project Digsig

Just a few interesting pointers to tools from a book I read:

• WHArsenal – www.whitesec.com (doesn’t seem to be available anymore)
• HTTPush – on the fly modification of requests (in Perl)
• WEBScarab – http://www.owasp.org/software/webscarab.html
• Spikeproxy – http://packages.debian.org/unstable/net/spikeproxy.html
• PenProxy – http://shh.thathost.com/pub-java/html/PenProxy.html

I found a nice program PQA written in Ruby to show query statistics based on database logs. That sound like almost exactly what I needed, so I tried it on MySQL MT log files and some other data. There were a few bugs that I fixed.

In addition I added a new report printing unique queries and when they occurred. It seems to work fine and with help of awk/make/gnuplot generated a few nice graphs.

Xdoclett seems to be a nice way of generating web.xml descriptor based on the JavaDOC style comments in a source code. From what Chris showed me, it looks it’s quite difficult to run though. (more…)
