Ruby script1. Editing OpenVPN configs by hand
It is necessary to edit OpenVPN config file to be authorized without username and password entering. Open selected config file (.ovpn) through text editor, replace line auth-user-pass by auth-user-pass auth.txt and save it.... auth-user-pass auth.txt ...OpenVPN client will get username and password from the file auth.txt which should be placed in the same directory as edited config file. The auth.txt must have 2 lines only: username on the first line and password on the second.
username password
The username and password are the same as the username and password of the DeepWebVPN Cabinet.
DON'T use the Notepad to edit a config file in the Windows, use WordPad, it shows UNIX like line breaks correctly.
2. Modified OpenVPN configs to auth without username and password entering
DeepWebVPN provides already modified OpenVPN configs to auth without username and password entering. There are available to download: archive of all OpenVPN configs, archive of the Single chains only and archive of the Double chains only.After unpacking downloaded archive don't forget to create file auth.txt like it is described in the Editing OpenVPN configs by hand subsection.
.
3. Scripts to modify OpenVPN configs
The described below scripts must have execute permission and be run in a appropriate interpreter.
The user who runs the script must have permission to modify config files.
