[VU+ Duo4K SE] Remote Access to box

[smp8]

Hi all

I've been trying to set up remote access to my VuDuo4k SE using an old 2014 post by Finbarr (https://www.world-of-satellite.com/showthread.php?36336-Guide-to-setting-up-an-OpenVPN-server-on-Vix), but can't get past building the CA certificate. It comes up with 'can't load /home/root/.rnd into RNG'

I did manage to get it up and running a few years back on my old VuDuo2. I just wondered if anyone had an updated version.

Many thanks
