the kernel also collects entropy from disk/network timing, and in many cases this provides more than enough entropy. however I do think using rngd to do a feedback input definetly has a place (/me recalls too many people reporting the blocking for input bugs...) in cvs now. Just as an addition. IMHO This topic should also be raised in the Installation Handbook of gentoo linux as configurating/using the RNG tools correctly is a very important part of the installation as this could lead to many different problems if one doesn't know that /dev/random is the cause for all his/her hangs. And please explain what you exactly changed in the cvs now concerning the rng-tools? As I really think they should be included in each default installation. Believe me, I have 2 servers here which ran out of entropy because they have heaps of memory so lots of disk access is anyway cached. It is really easy to reproduce that /dev/random blocks, so using a hardware random generator or the rng daemon on gentoo is a mandatory thing. |
