title: linux openvpn route add command failed
body: <p>I am trying to access my office vpn through their provided opvn file with my linux (ubuntu 14.04 LTS) laptop, but it is failing with following error:</p>
  
  <pre><code>Wed May  6 22:36:55 2015 /sbin/ip route add xxx.xxx.xxx.xxx/16 via yyy.yyy.yyy.yyy (actual ips hidden here)
  RTNETLINK answers: Invalid argument
  Wed May  6 22:36:55 2015 ERROR: Linux route add command failed: external program exited with error status: 2
  </code></pre>
  
  <p>The error repeats for many different ips.</p>
  
  <p>It does work through our windows 7 computer so it must be some configuration issue on the linux machine. And I would like some help to fix this.
  I am running openvpn through the terminal with a script doing the following:</p>
  
  <pre><code>1) change nameserver to company nameserver (sudo sed -i "s:127.0.0.1:xx.xx.xx.xx:g"  /etc/resolv.conf
  2) sudo openvpn --config /etc/openvpn/my_vpn_file.ovpn
  </code></pre>
  
  <p>I have been able to figure out that there probably somehow are multiple connections to the vpn..? So I guess the start would be to find and remove that/those other ones, but how?
  (I am not a complete novice in the linux world, but in the network/routing world - and stackoverflow!) </p>
  
  <p>Thanks in advance!</p>
