22 | The Linux kernel supplies a random number generator which is accessed
|
---|
23 | through <filename class="devicefile">/dev/random</filename> and
|
---|
24 | <filename class="devicefile">/dev/urandom</filename>. Programs that utilize
|
---|
25 | the random and urandom devices, such as <application>OpenSSH</application>,
|
---|
26 | will benefit from these instructions.

30 | When a Linux system starts up without much operator interaction, the
|
---|
31 | entropy pool (data used to compute a random number) may be in a fairly
|
---|
32 | predictable state. This creates the real possibility that the number
|
---|
33 | generated at startup may always be the same. In order to counteract
|
---|
34 | this effect, you should carry the entropy pool information across your
|
---|
35 | shut-downs and start-ups.
