i try to create a free vpn client of raspberry pi 3 to hide my ip address when i connect to the internet.to do that i install an openvpn from vpnbook.com on my rasbian stretch OS. this is what i do:

sudo apt-get update
sudo apt-get install openvpn
cd /etc/openvpn/
sudo wget https://certificate-vpnbook
sudo unzip certificate
sudo nano password.txt

i run this command:

sudo openvpn vpnbook-pl226-udp53.ovpn and get this error:

i also change the DNS address in this file: /etc/openvpn/server.conf from google dns server:

push "dhcp-option DNS"
push "dhcp-option DNS"

to push "dhcp-option DNS" push "dhcp-option DNS"

i search the warning and the result are about vpn server and mine is vpn client. i don't know how to solve my problem. i appreciate your help.

  • The first error shows that the password file is readable by other than the user running openvpn, You need to make it root readable only (chmod 600) – Charemer Jan 3 at 12:37
  • If you're looking for anonymity (instead of encryption security), you may wish to consider using your RPi as a Tor router. There was a good Q&A on that subject posted only recently... here's a link to make your RPi a Tor router – Seamus Jan 3 at 13:14
  • thank you but i think vpn could be more helpful. – ali Jan 3 at 19:17
