I'd like to chime in that I recently installed haveged myself and have seen a massive increase in available entropy. Haveged, as I understand it basically runs a fairly complex calculation (with lots of branches and things) in a loop. Because almost all CPUs these days are complex beasts, the time to perform the calculation varies with each loop (sometimes because of cache misses, or maybe a branch was optimized differently). Haveged monitors the differences in these times and populates a random pool based on it. This is then fed in to the kernel as another source of entropy. Haveged is amazingly useful on headless or virtual or appliance machines. > > -- > Pazns: U don't know about the drawer method? > Pazns: U take your schoolbag, empty it in a drawer, close it, > hop! clean up done! > Zeeln: Yeah but my drawers are all full… > Pazns: U don't know about the trash method?
