Thanks chrism01 for your help.
Best solution I found for the fastest scripted / generated entropy was:
Code:
while /bin/true; do dd if=/dev/urandom of=/tmp/100 bs=1024 count=100000; for i in {1..10}; do cp /tmp/100 /tmp/tmp_$i_$RANDOM; done; rm -f /tmp/tmp_* /tmp/100; done & /usr/sbin/corosync-keygen
Understood jpollard about good entropy, this was just needed as a scripted example. Thanks for your input.
