HP-UX Secure Shell A.04.70.021, A.04.70.022, and A.04.70.023 Release Notes

HP-UX Secure Shell and the Strong Random Number Generator
HP-UX Secure Shell requires that a random number generator be located on the system. It searches
for /dev/urandom and /dev/random (in that sequence) on the system and uses the first device
it finds. If it fails to locate these two devices, HP-UX Secure Shell uses its own internal random
number generator program. The /dev/urandom and /dev/random devices are available by
default on HP-UX 11i v2 and HP-UX 11i v3 systems. These devices can also be obtained for
HP-UX 11i v1 by downloading and installing the HP-UX Strong Random Number Generator
from http://software.hp.com. If you are using HP-UX Secure Shell on HP-UX 11i v1, HP
recommends that you install the Strong Random Number Generator product as it significantly
speeds up program initialization and execution time for some commands.
