Is this needed on OS6 6.1.5?

I don't have an OS6 box, so I can't tell. (And, of course, the addon I built for OS4 won't work on OS6 anyway; if you wanted to install haveged, you'd have to do so manually or by building an OS6 addon.)

Running cat on entropy_avail I´m getting pretty high values compared to what I had on OS4 before. # cat /proc/sys/kernel/random/entropy_avail 2005 # cat /proc/sys/kernel/random/entropy_avail 2560

Let this run for a minute or two and see whether the entropy_avail value stays up in that high range:

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

or run this and see whether the stream of random hex values scrolls continuously up the screen:

hexdump /dev/random

If the number displayed by the first test falls to a low number and stays down in a low range, or if the stream in the second test pauses for a second or more after every line, your machine's entropy pool is easily depleted and might benefit from the installation of haveged.
