OpenVPN is basically the defacto standard for open source VPN software. You are able to both connect to other VPN servers OR make your own, private VPN service.
sudo apt-get install openvpn unzip
PIA OpenVPN Files¶
PIA is Private Internet Access, a widely used and referenced VPN service for the fact that they advertise themselves as one of the more secure and anonymous VPN services on the internet. This page is a good jump-off point for explaining their services and why you need a VPN.
The OpenVPN files are configuration files tailored to be used with OpenVPN for PIA, making that ENTIRE setup SO much easier!
Download and uncompress the PIA OpenVPN profiles:
wget https://www.privateinternetaccess.com/openvpn/openvpn.zip unzip openvpn.zip -d openvpn
Make sure you include the
-d flag, as it’ll just uncompress into the current directory, flinging files all over it.
Copy the Files¶
Copy the PIA OpenVPN certificates and profile to the OpenVPN configuration location.
I’m using Japan.ovpn as an example location. You can/should change that to whichever location you want to use.
sudo cp openvpn/ca.rsa.2048.crt openvpn/crl.rsa.2048.pem /etc/openvpn/ sudo cp openvpn/Japan.ovpn /etc/openvpn/Japan.conf
You’ll notice I changed the file extension from
.conf. OpenVPN likes
Create the Login File¶
/etc/openvpn/login containing only your username and password, one per line. Of which, PIA randomly creates your username and password, which is extra-awesome for both security and anonymity
Change the permissions on this file so only the root user can read it, keeping anyone else from snooping.
sudo chmod 600 /etc/openvpn/login
Edit the Config File¶
Setup OpenVPN to use your stored username and password by editing the the config file for the VPN location, as well as our
sudo nano /etc/openvpn/Japan.conf
Change the following lines:
|From This||To This|
|ca ca.crt||ca /etc/openvpn/ca.rsa.2048.crt|
|crl-verify crl.pem||crl-verify /etc/openvpn/crl.rsa.2048.pem|
At this point you should be able to test that the VPN actually works.
Running it this way outputs the program info, as its running, into the terminal prompt. This way, you see up front without hunting in the logs for if/when/where there is any issues.
sudo openvpn --config /etc/openvpn/Japan.conf
If all is well, you’ll see something like:
sudo openvpn --config /etc/openvpn/Japan.conf Sat Oct 24 12:10:54 2015 OpenVPN 2.3.4 arm-unknown-linux-gnueabihf [SSL (OpenSSL)] [LZO] [EPOLL] [PKCS11] [MH] [IPv6] built on Dec 5 2014 Sat Oct 24 12:10:54 2015 library versions: OpenSSL 1.0.1k 8 Jan 2015, LZO 2.08 Sat Oct 24 12:10:54 2015 UDPv4 link local: [undef] Sat Oct 24 12:10:54 2015 UDPv4 link remote: [AF_INET]18.104.22.168:1194 Sat Oct 24 12:10:54 2015 WARNING: this configuration may cache passwords in memory -- use the auth-nocache option to prevent this Sat Oct 24 12:10:56 2015 [Private Internet Access] Peer Connection Initiated with [AF_INET]22.214.171.124:1194 Sat Oct 24 12:10:58 2015 TUN/TAP device tun0 opened Sat Oct 24 12:10:58 2015 do_ifconfig, tt->ipv6=0, tt->did_ifconfig_ipv6_setup=0 Sat Oct 24 12:10:58 2015 /sbin/ip link set dev tun0 up mtu 1500 Sat Oct 24 12:10:58 2015 /sbin/ip addr add dev tun0 local 10.10.10.6 peer 10.10.10.5 Sat Oct 24 12:10:59 2015 Initialization Sequence Completed

Setup OpenVPN’s Autostart Configuration¶
sudo nano /etc/default/openvpn
Next, since I use only the one
.conf file, I uncomment the
AUTOSTART-"all" line. If you have a different setup, go through and make those changes.
Then, to start the service:
sudo service openvpn start
Then, to check that my public-facing IP address has changed - since I usually am running this on a headless machine as a downloader - I have an alias assigned in one of my dotfiles. Of which, my breakdown of dotfiles is:
.aliases file is, well, my aliases that I use. So, for checking my public-facing IP address:
alias pubip="dig +short myip.opendns.com @resolver1.opendns.com"
Add that to either your
.bashrc file, whichever you are currenty using, and source the file. It adds the alias entry to the active session.
pubIP and hit enter. You should get your public IP address.
