setting up VPN on Ubuntu 16.04 build-ca error message

VPN Ubuntu 16.04

Running Ubuntu 16.04 on a HP Pavilion laptop
In following your tutorial "How to set Up an OpenVPN server on Ububtu 16.04" I got to step 4 "Build the Certificate Authority" and when I ran the ./build-ca command I got the following output:

Generating a 2048 bit RSA private key
unable to write 'random state'

writing new private key to 'ca.key'

As you can see it is telling me it can not write the random state. I want to know if I can ignore this message and continue or what I might try to fix it.

Any and all help is appreciated.

  • sorry I tried to bold the line "unable to write 'random state'" but it did it to the following line. I am new to this site.

  • While I wait for an answer I decided to try to continue.
    Upon running the ./build-key-server server I go the same message on the last line of the output:

    1 out of 1 certificate requests certified, commit? [y/n]y
    Write out database with 1 new entries
    Data Base Updated
    unable to write 'random state'

    Any and all help is appreciated.

Hi @raygolost

It's usually because your .rnd is not owned by the user. You can remove it:

sudo rm ~/.rnd
