Which will come to 32 printable characters. The result will be a 24-byte (192-bit) string, expressed in base 64 notation, Generate a password for Xor obfuscation: openssl rand -base64 24 In preparation for download to the client, make the client files readable by a non-root user: chmod +r ca.crtĮxit root session: exit Create OpenVPN Server Configuration FileĬhange into the OpenVPN server directory: cd /etc/openvpn easyrsa init-pkiĬopy the certificates and keys into the OpenVPN directories: cp pki/ca.crt /etc/openvpnĬp pki/issued/34.34.34.34.crt /etc/openvpn/serverĬp pki/issued/adminpc.crt /etc/openvpn/clientĬp pki/private/34.34.34.34.key /etc/openvpn/serverĬp pki/private/adminpc.key /etc/openvpn/client Switch to root: su - cd /usr/share/easy-rsa/3Ĭreate the public key infrastructure (PKI).

Open your firewall for udp traffic on port `443` (in our example). ![]() Make these changes effective: sudo sysctl -p Uncomment the line: _forward=1Īdd at the bottom of the file the lines: .disable_ipv6 = 1 ![]() Start by making sure your server is up to date: sudo apt-get updateĮdit the system configuration file: sudo vi /etc/nf To prepare the server to run OpenVPN with the Xor patch, we will allow packet forwarding, disable IPv6, open the firewall, and masquerade the source IP address of outgoing packets. We communicate between client and server via `udp` on port `443`, which you may need to change, depending on what restrictions apply on your network. ![]() The server public IP address is 34.34.34.34, which you will need to change to correspond to your actual server public IP address.The client runs Ubuntu Linux version 18.04.The server runs Ubuntu Linux version 18.04.The example given here makes these assumptions: In this article, we build OpenVPN with the Xor obfuscation patch. The Tunnelblick project then split it into five components. The Xor patch provides a modification that may allow OpenVPN to work in restrictive environmemts.
