I try to follow the HowTo:
https://openvpn.net/index.php/open-source/documentation/howto.html
I renamed the default vars.example file to vars and edited it:
Now edit the vars file (called vars.bat on Windows) and set the KEY_COUNTRY, KEY_PROVINCE, KEY_CITY, KEY_ORG, and KEY_EMAIL parameters. Don't leave any of these parameters blank.
Next, initialize the PKI. On Linux/BSD/Unix:
. ./vars
I do this and get this message:
~/EasyRSA-3.0.1# . ./vars
You appear to be sourcing an Easy-RSA 'vars' file.
This is no longer necessary and is disallowed. See the section called
'How to use this file' near the top comments for more details.
How do I proceed?
