USE_URANDOM for NetBackup servers and clients

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

Enable the USE_URANDOM option to specify /dev/urandom as the character device to provide cryptographically secure random output in your NetBackup environment.

Table: USE_URANDOM information

Usage

Description

Where to use

On NetBackup servers or clients.

How to use

Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option.

For information about these commands, see the NetBackup Commands Reference Guide.

The default value of the USE_URANDOM option is 0. When the USE_URANDOM option is set to default, the character device to be used is based on the value of the NB_FIPS_MODE option. If NB_FIPS_MODE is enabled, dev/random is used. If NB_FIPS_MODE is disabled, dev/urandom is used.

See NB_FIPS_MODE option for NetBackup servers and clients.

To enable the USE_URANDOM option, use the following format:

USE_URANDOM = 1

If USE_URANDOM is set to 2 (or is disabled), the dev/random character device is used to provide cryptographically secure random output.
