Random number generation in POSIX

As already announced, the POSIX prngd daemon is no longer provided. POSIX programs can address the BS2000 PRNGD either directly via the GPRBYTE interface or can use the device file /dev/urandom, which also obtains the random numbers from BS2000 PRNGD.

/dev/urandom is particularly suitable for scripts, which can access it using the dd command, for example.
