Problem with openvp is solved too. I chose ovpn file which contains my settings, but still i do not know why but it was using some other conf file.
I edited and selected my own conf file and it worked.

If you choose ovpn file you must not need to select conf file too. They are the same just with different extension. I used to use ovpn file on windows when used windows On linux conf extension.


That wifi tethering script which is in first post does not work for me on 2.1.3.7. It complains about tether parameter and says device not found.
