NetBackup™ Security and Encryption Guide

Specify entropy randomness in NetBackup

In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data.

This requirement is only for Linux platforms and with Java programs or processes.

You need to specify which randomness to use with JVM arguments. If not specified, it uses dev/random by default.

The following is specified as JVM arguments to the Java program: -DjavaDjava.security.egd=file:/dev/./random

Enable the use_urandom configuration option to make use of dev/urandom and restart the services or re-launch the NetBackup Administration Console.

See USE_URANDOM for NetBackup servers and clients.
