Important Note

After the ~Jan 2018 migration of Papio to a new VM at Duke with new security measures in place, all of the below information is no longer true. We are now using the Duke VPN.

(The below information kept for archival purposes only)

The VPN (Virtual Private Network) running on the Babase server uses the OpenVPN implementation.

Babase VPN on Mac OS X

You always have the option of installing the application using the instructions on the OpenVPN web site, but the easier way, if you've Mac OS X 10.3 or higher, is to use the pre-packaged OpenVPN called Tunnelblick that includes a management GUI. Babase supplies a pre-packaged version of Tunnelblick with configuation files built-in, but there may be newer Tunnelblick versions available on the Tunnelblick web site.

To install the Babase-supplied Tunnelblick version (obvious interactions omitted):

Tunnelblick is installed in your Applications folder. Double click on it to start the Babase VPN. Control Tunnelblick with the little tunnel icon at the top right of the screen. When it asks for your name and password, use your Papio name and password (in case these are different from your babase name and password).

See below regards using the Babase VPN.

Note: The OpenVPN configuration supplied with the Babase packaged version of Tunnelblick differs from the configuration linked below. The packaged configuration file does not drop root permissions since this seems to cause problems with packaged Tunnelblick version 3.3beta54.

If installing a newer Tunnelblick version you will need the following configuration files:

A Tunnelblick un-installer is avaialble on the Tunnelblick website.

Babase VPN on Windows XP

As Administrator, install OpenVPN GUI for Windows. Unless you already have OpenVPN (without GUI) installed on your computer, it is easiest to download and install the installation package with both OpenVPN and OpenVPN GUI. Once installation completes, you should notice a new OpenVPN GUI icon in your system tray (at the lower-right corner of your desktop). The icon should be lit red at this point, because you have not made a VPN connection yet.

Download the following two files, and place them in the C:\Program Files\OpenVPN\config\ directory on your computer:

Now, to connect, right click on the OpenVPN GUI icon in your system tray, and choose "Connect". You will be prompted for your Duke Biology Unix user name and password. If the connection is successful, the icon will turn green. To disconnect, simply right lick on the icon and choose "Disconnect".

Optional Tweaks to Configuration

By default, OpenVPN GUI will start in your system tray whenever your computer starts up. If you do not want this behavior, you can use AutoRuns for Windows to tweak it.

If you normally use your Windows XP computer as a non-Administrator user, you should create a shortcut to C:\Program Files\OpenVPN\bin\openvpn-gui.exe, right-click on the shortcut, select "Properties", click "Advanced..." and select "Run with different credentials". Now, when you double-click this shortcut, you should choose to run it as Administrator (VPN will not function correctly if you do not run it as Administrator). The How-To section of the OpenVPN GUI website has more information on how to run VPN as a non-admin user.

Notes on Using the Babase VPN

When you start the VPN you will be asked for your Duke Biology Unix user name and password.

Testing A Connection to Papio

To test the VPN use the "ping" program to ping (aka If you get a response the VPN is working.
