12<para>The Linux kernel supplies a random number generator which is accessed
13through <filename class="devicefile">/dev/random</filename> and
14<filename class="devicefile">/dev/urandom</filename>. Programs that utilize
15the random and urandom devices, such as <application>OpenSSH</application>,
16will benefit from these instructions.</para>
18<para>When a Linux system starts up without much operator interaction, the
19entropy pool, data used to compute a random number, may be in a fairly
20predictable state. This creates the real possibility that the number generated
21at startup may always be the same. In order to counteract this effect,
22you should carry the entropy pool information across your shut-downs and
