On rapsberry pi you need to manually activate loading module bcm2708-rng, or so I have read, to enable the HW-support. I have not actually verified the current state or tested it on my relays. The nodes are headless and normally outside my firewall so it's a bit of work to do the maintenance. But I wanted to get some confirmation that it is useful to do it.
It could be fun to make some benchmarking to see if I can increase performance on the same hardware. How do I examine the output of 'openssl' that too is a bit of unknown territory for me? 2015-03-13 21:39 GMT+01:00 Libertas <[email protected]>: > On Thu, Mar 12, 2015 at 07:01:58PM +0100, Imse Vimse wrote: > > Would enabling the hardware random number generator on a relay node be > > usefull in terms of increased performance? > > If so, is it enough to activate /dev/hwrnd or is some configuration > > and/or recompilation required? > > I suspect that your OS already does this by mixing it into its entropy > store, but that Tor using the device directly would be dangerous. > > I'm not sure how relevant the HardareAccel config option is, but you > might want to look into that.
