Tool to make graphs out of psad CSV output together with psad and the GraphViz package
psad --CSV -CSV-fields "src dst dp" -m /var/log/iptables | fluo.py | neato -Tgif -o output.gif
There is no way to filter data, nor do I plan on adding one. You can simply harness the power of grep to do so, like this.
psad --CSV -CSV-fields "src dst dp proto" -m /var/log/iptables | grep -v icmp | fluo.py | neato -Tgif -o output.gif
This excludes ICMP traffic
