MvL Posted April 25, 2019 Posted April 25, 2019 I just noticed today during booting of unRAID server I see loading the "haveged daemon" when I google I came to the following site: http://www.issihosts.com/haveged/ What is the purpose for this daemon? Were is it used for in unRAID? Quote
Marshalleq Posted April 26, 2019 Posted April 26, 2019 I think random number generators are pretty standard in all *nix operating systems. I would guess it's not actually an Unraid specific thing, rather a linux specific thing. Someone else can chime in what they're actually used for, but suspect google will tell you that too. I think crypto stuff like ssh and ssl use it (or similar) for a start but someone may correct me. Quote
mgutt Posted October 16, 2020 Posted October 16, 2020 (edited) haveged is loaded through Unraid in "/etc/rc.d/rc.M": # Start the haveged entropy daemon: if [ -x /etc/rc.d/rc.haveged ]; then /etc/rc.d/rc.haveged start fi If I download a file haveged produces load: I stopped the service as follows: /etc/rc.d/rc.haveged stop Stopping haveged. I found no impact. The server runs as usual. So same question. Why is it needed? EDIT: Regarding this blog post haveged becomes active if the entropy of haveged is stronger than the one of /dev/random (linux default). So it adds a little bit more strength to the smb encryption while transfering the file. Conclusion: Produces load, I don't need it. Will be disabled by default through the Go File: # ------------------------------------------------- # disable haveged as we trust /dev/random # https://forums.unraid.net/topic/79616-haveged-daemon/?tab=comments#comment-903452 # ------------------------------------------------- /etc/rc.d/rc.haveged stop Edited October 16, 2020 by mgutt 1 Quote
vakilando Posted May 22, 2022 Posted May 22, 2022 I know, it's an old thread.... Just for information: I tested the command on my upgraded Unraid (6.9.2 to 6.10.0) and commented out the line in the go file. /etc/rc.d/rc.haveged stop -bash: /etc/rc.d/rc.haveged: No such file or directory 1 Quote
