How about Haveged ( Linux entropy source using the HAVEGE algorithm.)?
Code:
apt-get install -y haveged
The entropy pool size in Linux is viewable through the file and should generally be at least 2000 bytes (out of a maximum of 4096).
Check your entropy pool by running:
Code:
cat /proc/sys/kernel/random/entropy_avail
This command shows you how much entropy your server has collected. If it is rather low (<1500), we should probably start haveged. Otherwise cryptographic applications will block until there is enough entropy available.
