    * Just type away for a bit, randomly. You can even redirect it to 
/dev/null:

# cat >/dev/null

      Just type stuff away, and when you're done, hit ctrl-d to stop 
the cat'ing to /dev/null. Then re-run passwd.
Result: Not being tested yet, as I don't see a fundamental difference 
compared to typing junks on the keyboard. If the random device is not 
working properly, it still not going to work no matter how you input 
random characters.

    * As Matthew Seaman pointed on on the -questions list, you can just 
run vipw and delete the stuff between the second and third ':', leaving 
a blank password. Then you can reboot normally, login to root 
immediately(!!) and run passwd. The generator will be nice and warmed up.

Result: I've been using blank password thru out all installation, and 
created root password after login root, then reboot, it still have tne 
same error.

    * I guess on FreeBSD 5.x, which I haven't tried to install yet, you 
can run:

# /etc/rc.d/preseedrandom

      Which, in fact, preseeds the random number generator.
Result: this is new to me, I tried it, but does not fix the problem.

Apart from using the entropy way to genenrate host_keys, why can't base 
on user's root password generate host_keys? Is there any other way 
(commandline) of  sshd generate host_keys?
