How to create entropy?

[Christian Baer <christian.baer%uni-dortmund.de@localhost>]

Hi there people!

I'm kinda stuck, creating a cgd. The problem is that it hangs while 
creating the config file. The guide says that this is because there 
isn't enough entropy. Somehow I find that hard to believe especially 
since I *did* wipe the device as recommended earlier in the guide. There 
should be plenty of entropy to graze from. :-)

Moving the mouse or hitting keys on the console is a bit of a problem as 
the machine has none. I only access it via ssh. I do have a serial 
console but I went on hammering the keyboard for several minutes without 
cgdconfig finishing it's job.

What can I do? How do I create a lot of randomness?

Regards,
Chris
