on a sidenote, using /dev/urandom is a bad idea. f.e. the standard slackware install and other distros as well have the following code (or something similar) in /etc/rc.d/rc.S: # Carry an entropy pool between reboots to improve randomness. if [ -f /etc/random-seed ]; then echo "Using /etc/random-seed to initialize /dev/urandom." cat /etc/random-seed > /dev/urandom fi # Use the pool size from /proc, or 512 bytes: if [ -r /proc/sys/kernel/random/poolsize ]; then dd if=/dev/urandom of=/etc/random-seed count=1 bs=$(cat /proc/sys/kernel/random/poolsize) 2> /dev/null else dd if=/dev/urandom of=/etc/random-seed count=1 bs=512 2> /dev/null fi chmod 600 /etc/random-seed Guess where's the rub... --
