    <p>I am tring to connect a remote server via openvpn using C#. I am able to connect it successfully. but disconneecting seems to not work properly. Once I close my app, I am not able to access the internet. I got to manually disable the TAP Adapter and then enable to execute the app again. I checked my "route print" and yes Tap is coming ahead of internet and hence couldn't access net.</p> <p>I connect using : openvpn --config client.ovpn --ca certificate.cer --auth-user-pass user.txt</p> <p>My disconnecting code is :</p> <pre><code> public void DisconnectServer() { // Write the logs if (sb != null) IOUtility.WriteToFile(sb.ToString(), "ConnectionLogs.log"); processInfo = null; if (process != null) { //process.Close(); if (!process.HasExited) { process.CancelOutputRead(); ProcessThreadCollection ptc = process.Threads; Console.WriteLine("////// PROCESSED THREAD = " + ptc.Count); for (int i = 0; i &gt; ptc.Count; i++) { ProcessThread pt = ptc[i]; pt.Dispose(); ptc.Remove(pt); Console.WriteLine("REmoed Thread @ " + i); } process.CloseMainWindow(); process.Kill(); } } sb = null; connected = false; } </code></pre> <p>On searching net for this issue, I found to use management to exit the openvpn safely. But I cannot make how to run the managemetn code. While start I added : openvpn --config ca.ovpn --ca cert.cer --management 127.0.0.1 12345 Then how to give SIGTERM signal to close the openvpn. In new cmd, I tried : openvpn --management-signal SIGTERM but things doesn't work.</p> <p>OpenVpn will not be installed as a Service, so I guess can't use --service attribute.</p> <p>Can anyone guide me where am I going wrong in disconnecting. How to handle the managemetn-signal code. Which is the best way to disconnet from openvpn server. Can I also exit the openvpn itself ?</p> <p>Kindly help me. Have searched a lot on internet and found some help but no sucess yet. Stuck on this issue.</p> <p>Thanks</p>

    3. COOh yes, I had found that first only i guess. And from their only I got to know about SIGTERM of management. But I am not able to execute that command so have asked for that also above. Maybe I am doing something wrong or incorrect, what I can't make out. I have put all possible solutions I found and can or cannot implement. Regarding exiting service I found from http://stackoverflow.com/questions/1195210/c-close-openvpn-cleanly .
