title: Unable to install openvpn-2.3.6 on Ubuntu 14.04 LTS to work work with TUN/TAP
body: <p>I'm trying to install openvpn-2.3.6 on Ubuntu 14.04 LTS to work with TUN/TAP.</p>
  
  <p>I have downloaded the package from:
  <a href="http://swupdate.openvpn.org/community/releases/openvpn-2.3.6.tar.gz">http://swupdate.openvpn.org/community/releases/openvpn-2.3.6.tar.gz</a></p>
  
  <p>extracted it and try to install it using command line terminal.</p>
  
  <p>but the following error apperared:</p>
  
  <p><strong>"configure: error:  ssl is required but missing</strong>"</p>
  
  <p>How can I solve this problem to complete openvpn-2.3.6 installation?</p>
  
  <p>I'm following the instructions in the following link:
  <a href="http://backreference.org/2010/03/26/tuntap-interface-tutorial/">http://backreference.org/2010/03/26/tuntap-interface-tutorial/</a></p>
  
  <p>which uses the openvpn tool to configure the virtual tun interface.</p>
  
  <p>Can I make tunnels and configure tun interface without the assestance of openvpn or any other tool.</p>
  
  <p>do any one have simple example for using tun on ubuntu?</p>
