Failed to start rng-tools.service

Support Installation and Configuration

Briefly describe your issue below:

Hi - relative newbie here so please be (relatively) gentle…

I’ve created a Parrot USB with persistence and all works fine with the exception of two error messages on start up. The first being that it has failed to start rng-tools.service.

I’ve tested it as follows and all seems to be working fine?

┌─[user@parrot]─[~]
└──╼ $dd if=/dev/random of=/dev/null bs=1024 count=1 iflag=fullblock
1+0 records in
1+0 records out
1024 bytes (1.0 kB, 1.0 KiB) copied, 0.00152654 s, 671 kB/s
┌─[user@parrot]─[~]
└──╼ $

Does this indicate that the error message is wrong? Do I need to worry about this?

Cheers, James

Check it with systemctl status rng-tools.service
This will show the status of rng-tools, if you see any please copy here

I dont think rng-tools is even installed.
At least it isnt for me, that might explain why it failed to start.

Nevertheless its used to improve entropy in the kernel, so i dont think is essential.

4

Are you using Home or Sec?
In the Sec it is preinstalled for me

5

I’m also using Sec and it says FAILED during the boot sequence and when I run the status command I get:

rng-tools.service
Loaded: loaded (/etc/init.d/rng-tools; generated)
Active: failed (Result: exit-code) since Sun 2018-10-14 06:10:22 CDT; 1 day 6
Docs: man:systemd-sysv-generator(8)
Process: 800 ExecStart=/etc/init.d/rng-tools start (code=exited, status=1/FAIL

Is there a way to fix?

6

What does this command show?
sudo journalctl -u rng-tools

hm, i found nothing :frowning:
what did you do before this issue?
Is this a fresh install ?

9

I had downloaded and verified the ParrotSec image, used dd with bs=512k to install to a USB drive, used shred to clean my drive then did a fresh install. I think it always gave me that error. I am going to load up my live USB and see if the problem was there from the beginning. Maybe it somehow got corrupted.

10

Try purging it and then re-installing maybe.

11

Will try and report the outcome

12

Okay I purged and attempted to install again:

Still seems broken

Did you reconfigure/install anything dealing with xserver,X11,nvidia, or the desktop environment? That is the only (albeit brief, obviously fixing rng for me needed to have the root issue fixed) time ive had that error myself.
