Another way may be using iptables accounting..for example: iptables -N udp-out iptables -A udp-out -j accept iptables -N udp-in iptables -A udp-in -j accept iptables -A input -p udp -j udp-in iptables -A output -p udp -j udp-out you can see this with: iptables -L -n -v -x ..i have some perl scripts to show that in graphs (rrdtool, gnuplot, etc)... saludos Esteban.
