random number generator

Yewen Tang — Wed, 12 Jul 2000 19:38:07 GMT

I'm working on HP-UX 11.00 (visulize workstation 785). It seems to be lack of a random number source like /dev/random on other UNIX. I installed a EGD. Some applications work with it. Some don't. Can I install something like /dev/random as a default random number source for other application? What software should I install?

HP-UX does not have a /dev/random but does have random(3M) that will generate random numbers using a different method.

HP-UX does not have an equivalent of /dev/random, but you could take a look at the command
random(3m)

DESCRIPTION
The random() and srandom() functions are random-number generators that
have virtually the same calling sequence and initialization properties
as the rand() and srand() functions,

To generate a random number between 1 & 10

((num=RANDOM %10 + 1)) ; print $num

For cryptographical use, random is of course worthless. IMHO HP has totally forgotten to offer a decent source for random number generation -- thus EGD is your only chance.

I believe awk also offers random number generation via rand().
