![]() OpenVPN asks Tunnelblick for these items as needed. OpenVPN setups often use the -auth-user-pass option in client configurations to specify that a username and password are required to connect the VPN, and a passphrase may be required to unlock a private key. Tunnelblick and Usernames, Passwords, and Passphrases When combined with the "old" method of updating configurations (see below), this allows a single update to contain updates for all configurations. "EnclosingConfiguration.tblk" is used as a container for the folder structure that contains the actual VPN configurations. For details, see Nested Configurations.įor example,the following single Tunnelblick VPN Configuration sets up six configurations contained in three folders: Tunnelblick can include one level of configurations within a configuration, and configurations can be contained in folders and subfolders to any depth. Nested Configurations and Configurations in Folders However, configurations or changes which are not security sensitive may be installed by a standard user (without authorization by a computer administrator) if a computer administrator has previously un-checked the "Require computer administrator authorization to install all configurations" checkbox on the "Preferences" panel of Tunnelblick's "VPN Details" window.įor details, see Standard Users Installing or Replacing Configurations. Non-administrator Installations and Updates of VPN Configurationsįor security reasons, by default Tunnelblick requires a computer administrator's authorization to install or update VPN configurations. For details, see Automatically Install Configurations and Forced Preferences. Tunnelblick can install "forced" preferences (settings that cannot be modified by a standard user) at the same time that Tunnelblick itself is installed, using the same computer administrator authorization. Automatic Installation of Forced Preferences when Tunnelblick is Installed ![]() Tunnelblick can install Tunnelblick VPN configurations at the same time that Tunnelblick itself is installed, using the same computer administrator authorization. Preferences Related to Usernames, Passwords, and Passphrases Non-administrator Installations and Updates of VPN Configurations Viscosity has a version for Windows, too.Automatic Installation of Configurations when Tunnelblick is InstalledĪutomatic Installation of Forced Preferences when Tunnelblick is Installed Viscosity also includes the necessary kexts and I believe it also imbeds an OpenSSL library in its OpenVPN binary. If you want to "do it yourself", you'll need OpenVPN and either a tun or a tap kext (or both, depending on your configurations), and you may want a newer version of OpenVPN. If you use Tunnelblick, that's all you need - it contains everything you need. That is almost always an old version and will not include some high-key-length ciphers, which means they wiil be unavailable. If you use a version of OpenVPN that does not imbed OpenSSL, OpenVPN will use the command-line version of OpenSSL included in your version of OS X. Tunnelblick also includes binaries of two versions of OpenVPN with the latest version of the OpenSSL library imbedded in each. Tunnelblick includes several versions of each of the tun and tap kexts (one for OS X 10.4 and 10.5, one for 10.6 - 10.8, and one for 10.9) and loads/unloads the appropriate version dynamically as the VPN is created/destroyed. The kexts used by Tunnelblick are from the tuntaposx project. ![]() The kernel extension (kext) that is needed is either a "tun" or a "tap" kext, depending on which type of VPN you are creating (it is something specified in the OpenVPN configuration file, and must be the same on the server and the client).
