      Has anyone used OpenVPN on Android?

      I have to add the connection to a client device, but I don't have any (found) documentation on the process.

        OpenVPN has many variables. First step is getting the app, which I've never seen and don't know if there are one or many different ones.

        The second is getting the documentation on the OpenVPN implementation at the site. There is no generic OpenVPN setup.

              Did you get the details from the existing OpenVPN infrastructure?

                I have. Basically, you have to import prepared configuration file (profile) into OpenVPN client. I transfer it to Android either via email or via web site. Sometimes, if you copy file from Windows to SD card it gets converted into dos format which causes problems for Android client.
                Also, consider using the unified format for OpenVPN profiles which allows all certs and keys to be embedded into the .ovpn file.

                  Okay - totally not sure about what all that is talking about - BUT - BUT - I think I understand...

                  I don't have any ovpn files,.. I do have I believe text which could BE the ovpn file. And this information needs to be sent to the tablet and imported to the OpenVPN application - which appears to be pretty straight forward.

                      sample unified ovpn profile:

                      client
dev tun
proto udp
remote vpnserver.something.com 1194
resolv-retry infinite
nobind
persist-key
persist-tun
verb 1
cipher AES-256-CBC
auth SHA1
dhcp-option DNS 8.8.8.8

# SMB WINS name server if you have one
#dhcp-option WINS 192.168.1.1

# route to multiple networks
route 10.0.0.0 255.255.0.0


# CA cert
<ca>
-----BEGIN CERTIFICATE-----
.... CA content
-----END CERTIFICATE-----
</ca>

# VPN Client Certificate
<cert>
-----BEGIN CERTIFICATE-----
.... client cert
-----END CERTIFICATE-----
</cert>

# key
<key>
-----BEGIN RSA PRIVATE KEY-----
.......key
-----END RSA PRIVATE KEY-----
</key>

                      it depends on your server setup. Put your CA cert, client cert and private key at appropriate positions. Save it as client.ovpn and import into OpenVPN client.

                        so it should not be a separate file

                          @gjacobse it can be, but it is much easier using unified format. Otherwise you need all files in same place and you have to pay attention if paths are correct.

                            Cool - Great. Imported.

                            just one more hurdle to pass..

                              Doing a bit of reverse name matching... I may have it now.
