Let's encrypt duplicated my log files

I have not been keeping log files for my web server until the beginning of 2016, when I needed to trace access to certain files (I started to use awstats, mostly because I was familiar with it since I had used it years ago when my site was still running on a Red Hat server). In March 2016 I luckily started to use Let's Encrypt. I had used another "free" service before, which got recently into big trouble as they apparently had not control over their own security.

How to start openvpn or ssh server under Ubuntu 16.04 and 18.04

sudo systemctl start openvpn@client
The "client" is derived from the configuration file name (/etc/openvpn/client.conf). If your configuration file is server.conf, the command needs to be
sudo systemctl start openvpn@server
When you want the service to start up automatically during system boot, you issue:
sudo systemctl enable openvpn@server
