Copy OpenVPN settings from Tunnelblick on Mac OS X to Windows 7

I forgot the charger for my job laptop in the office today. So I spent the last few minutes of battery copying the configuration files to the pc at home.

Below is what I ended up doing:

1. Install OpenVPN software. You can find it on the official OpenVPN site.
2. Copy all the config files from the job laptop to C:\Program Files (x86)\OpenVPN\config. The job laptop uses tunnelblick, so the files was located under
   ~/Library/Application Support/Tunnelblick/Configurations
3. Added .opvpn to the file name for the main configuration file (the one that is not .crt, .csr or .key)
4. Change to Windows style line endings. I did this by opening the files in WordPad, copying the contents to a Notepad window and saving.
5. Starting the client software.

Of course: There was a lot of trial and error. I guess I ended up using 30 minutes tinkering and 30 minutes blogging.

Gotchas:

• Make sure all line endings are corrrect. You can see this easily by opening the files in Notepad.
• Make sure you run the OpenVPN program as administrator.
