VPN Client Setup

Linux

To connect to Access Server from a Linux client computer, you need to follow these steps:

   1. Install an OpenVPN client for Linux

   2. Login to the Access Server's Client Web Server and download the desired client config file (typically called "client.ovpn"

   3. Run the OpenVPN client with the downloaded client config file

Installing an OpenVPN client:

Usually, the easiest way to install an OpenVPN client is to use the package management system for your particular Linux distribution. Run one of the following commands (as root):

apt-get install openvpn

Usually, the easiest way to install an OpenVPN client is to use the --config argument to specify the location of the downloaded client config file:

openvpn --config client.ovpn

Windows

Then install that client s/w after the successful installation it will ask username and password.

Save the username and password with OpenVPN Windows

I have followed some steps found in Internet, But not suceeded. Here I am giving one trick for save the username and password.

1)Install the windows client configuration file

2)Find out the config directory using log file

3)Copy the .ovpn file and move to another folder

4) Then un install the client

5)Download and instalhttp://s6n.org/dl/openvpn-2.1_rc19-passwordsave-install.exe . The official releases from openvpn.net will refuse to save passwords.

6)Then open the OpenVPN configuration directory (Start -> Programs -> OpenVPN -> Shortcuts -> OpenVPN configuration file directory) and create a new text file named "password_pass.txt" .

Open this file with Notepad. Enter your username on the first line and your password on the second line. Save and close the file.

7)Open the config file ".ovpn" file we have already copies with Notepad and look for the line "auth-user-pass" near the end.
Add arethusa_pass.txt at the end of this line, so that it looks like:
auth-user-pass password_pass.txt

Save and close the config file.

Then moved it into the config directory

Next time you connect to the VPN, you won't be asked any username or password.

Be sure that nobody else than you can use this computer.

Note: You have surely noticed that the Windows version of OpenVPN doesn't offer you the possibility to save your username and password. Not saving passwords is best for security, but quite annoying.
