Expressvpn setup under linux thru openvpn is possible under porteus or slackware:
1.0 Install openvpn see above in this thread
Which VPN provider do you recommend located in Europe?
2.0 Download expressvpn server location or locations addresses:
https://www.expressvpn.com/setup#manual
for example for montreal :my_expressvpn_canada_-_montreal_udp.ovpn
Open terminal, but do not enter command yet:
root@porteus:/home/guest/Downloads# openvpn --config
Copy-paste the downloaded expressvpn server address or simply drag it to the terminal window. Remove the quotes character at each end of the address.
Now hit the enter button. You will be requested user name and password.
3.0 Enter user name and password.
Find your email confirmation of service for expressvpn. Select setup expressvpn, manual config, openvpn config.
Go to step 2 , as we already done step one by downloading an expressvpn server location address. Both username and password are there.
4.0 Install expressvpn google chrome app:
https://www.expressvpn.com/fr/get-brows ... ion/chrome
The problem is that you have to have the openvpn active with username and password to have the expressvpn google chrome app to work. This is not the case under the debian application which seems to be in synch with the chromium app.

Prendre son temps, profiter de celui qui passe.
