Hello,
any tips how to generate entropy in the vm? My usual friend haveged fails.

# cat /proc/sys/kernel/random/entropy_avail

Thanks,
Tomas

i think you generate entropy on the host then import it to the vm.

 

other tips ive seen are to generate the crypto data then import the data to the vm/server in the wild.

 

i've tinkered with fortuna and csprng  https://code.google.com/p/csrng/

 

i haven't posted this info to the wiki because im not done and haven't tested it under useful conditions.

 

which vm software are you using?

Paul: [about Percy] The man is mean and careless and stupid, and that's a bad combination in a place like this.

Hello, I'm using the Funtoo Linux Hosting virtual machine - that is OpenVZ.

 

Entropy can be imported, but it must be generated on demand, because it will eventually drain. Linux itself generates entropy (hw interrupts, keyboard, network), but it's not enough if you have a busy SSL machine.
