[gentoo-hardened] Running short of entropy...

[Ed W]

Hi, running an up to date hardened+grsec+pax on x86_64bit system (quad 
core2) and I think I may be running short of entropy, presumed due to SSP?

Essentially I have two or three digit numbers from 
/proc/sys/kernel/random/entropy_avail
The grsec "larger entropy pools" option is enabled

The LFS notes suggest that erandom is a possible solution.  Does anyone 
have any notes on dropping SSP into a lower quality/faster random number 
source?

I don't have physical access to all machines, so any interesting cheap 
random number generator dongles would be interesting to know about, but 
will not be a full solution in this case. If I'm missing some obvious 
option which is available on recent Intel/AMD hardware which might give 
me larger amounts of entropy then please shout?

Thanks for any advice

Ed W
