Highlighted Articles Discussion Group | On This Page The Tunnelblick ApplicationThe Tunnelblick application, Tunnelblick.app, must be stored directly in /Applications on the startup volume for security reasons. Thus it cannot be used from network drives or internal or external drives including thumb or flash drives, CD/DVD drives, etc. unless they are being used as the startup volume. Running Tunnelblick from from anywhere except /Applications on the startup volume will result in an offer to install Tunnelblick in /Applications on the startup volume. OpenVPN, Drivers, and Standard ScriptsThe OpenVPN program, openvpn-down-root.so, the 'tun' and 'tap' kext driver files, and standard client up/down scripts are included with, and contained within, Tunnelblick.app. Log FilesLog files are stored in /Library/Application Support/Tunnelblick/Logs. (Early versions of Tunnelblick stored them in /tmp/tunnelblick). The log files for a configuration are created or deleted and recreated each time the connection is made. There are two log files for each configuration, an OpenVPN log file and a scripts log file. The contents of the files are merged in the display in Tunnelblick's 'VPN Details' window. Key and Certificate FilesThese may be stored anywhere, but typically they are stored in the same folder as the configuration (.ovpn or .conf) file. Key and certificate files associated with a Tunnelblick VPN Configuration (.tblk) are stored inside the configuration itself. Key and certificate files usually have an extension of .cer, .crt, .der, .key, .p12, .p7b, .p7c, .pem, or .pfx. Configuration FilesThere are two types of configuration files:

Custom ScriptsThere are two types of custom scripts that can be run at certain points in the connect/disconnect process:
These scripts should be located in a Tunnelblick VPN Configurations without any folder structure, and references to them should not contain any path information.

The daemon has a .plist file named net.tunnelblick.tunnelblick.tunnelblickd.plist in /Library/LaunchDaemons. If a configuration is set to connect when the computer starts, it has a .plist file located in /Library/LaunchDaemons. These .plist files are all named starting with 'net.tunnelblick.startup.' PreferencesA user's Tunnelblick preferences are contained in Note: In Tunnelblick 3.2beta10 and earlier, preferences are stored in Deployed versions of Tunnelblick may contain a 'forced-preferences.plist' file within the Tunnelblick application itself. They are used to override the user's normal preferences; see Deploying Tunnelblick for details. Tunnelblick VPN Configurations may also include preference defaults, which are used to initialize the user's preferences (which may then be changed by the user).
