#1 Re: Installation » Haveged is or is not recomended? » 2019-12-30 00:50:14

Posted this to  freenode #devuan:
I thought haveged was installed by default with the system (ASCII 2.1) but I was wrong.
It seems to me that it should be, but maybe there is a reason that it is not. I have looked
around a little and I have not found any guidance.  Should I install it? This is on a
personal computer. If there are some parameters or considerations – what are they?
I am new to chat so please excuse my startup clumseyness.

Someone named debdog sent me to https://issihosts.com/haveged/
Then I looked at https://unix.stackexchange.com/question … py-quality
Then I did this in    /proc/sys/kernel/random

# for fname in $(ls)         do      print  $($fname) = $(cat $fname)       done

boot_id = a0317a59-6850-4792-988c-edccc4257942
entropy_avail = 3512
poolsize = 4096
read_wakeup_threshold = 64
urandom_min_reseed_secs = 60
uuid = aca2695e-d69a-4fbf-99fd-ed2b3401f7f1
write_wakeup_threshold = 1024

Then ran it again
# for fname in $(ls)^Jdo^Jprint  $fname = $(cat $fname) ^Jdone
boot_id = a0317a59-6850-4792-988c-edccc4257942
entropy_avail = 3269
poolsize = 4096
read_wakeup_threshold = 64
urandom_min_reseed_secs = 60
uuid = e632e645-8255-4c09-a558-4943102393f4
write_wakeup_threshold = 1024

Then read the man page for uuid.  Now I know how much I dont know (again).
I hope this saves someone some time.

I am on: Devuan
Linux 4cpu 4.9.0-11-amd64 #1 SMP Debian 4.9.189-3+deb9u2 (2019-11-11) x86_64 GNU/Linux
I thought I read somewhere that haveged was no longer needed because that function was in the kernel now.
