dnssec-keygen & /dev/random

[Vinson Armstead - PA]

Trying to use dnssec-keygen to generate key for zone xfers and this is the
message 

"You must use the keyboard to create entropy, since your system is lacking
/dev/random (or equivalent)"

I tried using the keyboard as input but after an hour of typing I still had
not key!

I am running Solaris 8....

How do I get /dev/random on my system or some automated way of generating
random keys

Thanks in advanced
