re: getting it going on Whonix, I needed to make modifications to the gateway, there wasn’t a smooth path to getting it to load files from other locations, and cut/paste doesn’t work under VirtualBox because the needed extensions are not included. I finally ended up pulling what I needed to the workstation, using python -m SimpleHTTPServer to provide a way to move the files over.
I think wget would be fine in this instance - all we’re talking about is a single text file for OpenVPN, 151 lines total only 67 lines of actual config, easy to verify. The only other things needed are OpenVPN in the 2.3.x series and the OpenSSL to support it.
Some of the friction is that I’m new to Whonix, I’m sure I went the long way round getting it running.
