netstat -ntu | tail -n +3 | awk '{print $5}' | sed 's/:[0-9]*$//' | sort | uniq -c | sort -rn Do not use this in production! This is a true hardware random number generator using your system as the entropy source. It models flipping a coin by pitting a fast clock (the CPU) against a slow clock (the RTC). The CPU models the coin flipping head over tails during flight and the RTC models the duration
